Abstract:
Abstract CASE DESCRIPTION A 12-year-old 32-kg neutered female crossbreed dog was treated for a large lumbosacral skin defect. CLINICAL FINDINGS The dog had sustained multiple, penetrating dog bite wounds to the lumbosacral and gluteal regions 5 days earlier. The referring veterinarian had initiated treatment with amoxicillin–clavulanic acid, which was continued at a dosage of 8.75 mg/kg, SC, every 24 hours at the referral hospital. Examination of the skin defect revealed a large subcutaneous abscess in the dorsal lumbosacral region with draining perimeter tracts at the wound margin. The partial-thickness wound measured 24 × 35 cm and had multifocal regions of necrosis extending caudally from the dorsal aspect of the T11 vertebra to the tail base. The skin defect was bounded by discolored and necrotic skin edges. TREATMENT AND OUTCOME The dog underwent extensive soft tissue wound reconstruction. A single, large, meshed full-thickness free skin graft was harvested from the left dorsolateral aspect of the thorax and grafted to the dorsal lumbosacral region, thereby enabling successful closure of the wound defect. Primary healing of the wound eventually occurred, without postoperative complications. CLINICAL RELEVANCE Use of a large, meshed full-thickness free skin graft led to a satisfactory outcome for this dog but required challenging postoperative management. Application of single, large, meshed full-thickness free skin grafts may be an option to manage large skin deficits in the lumbosacral area in dogs.

Abstract:
Neurofibromas are benign tumors of the peripheral nerve sheath. Spinal neurofibroma often asymptomatic. Symptoms may present include sensory changes. Neurofibroma mostly encountered cervical cord, difficult to distinguish from schwannomas. This slow growing tumor remodel the bone resulting pedicle thinning and posterior vertebral body scalloping. MRI shows hyperintense rim. Although this highly suggestive neurofibroma, occasionally also seen in schwannoma and malignant PNST. Treatment choice for symptomatic lesions is surgery. We are reporting a case of neurofibroma in the 5th lumbar and 1st sacral region.

Abstract:
We previously demonstrated that administration of norepinephrine, dopamine, and serotonin into the lumbosacral defecation center caused propulsive contractions of the colorectum. It is known that the monoamines in the spinal cord are released mainly from descending neurons in the brainstem. In fact, stimulation of the medullary raphe nuclei, the origin of descending serotonergic neurons, enhances colorectal motility via the lumbosacral defecation center. Therefore, the purpose of this study was to examine the roles of the noradrenergic nucleus locus coeruleus (LC) and dopaminergic nucleus A11 region in the defecation reflex. Colorectal motility was measured with a balloon in anesthetized rats. Electrical stimulation of the LC and A11 region increased colorectal pressure only when a GABAA receptor antagonist was injected into the lumbosacral spinal cord. The effects of the LC stimulation and A11 region stimulation on colorectal motility were inhibited by antagonists of α1-adrenoceptors and D2-like dopamine receptors injected into the lumbosacral spinal cord, respectively. Spinal injection of a norepinephrine-dopamine reuptake inhibitor augmented the colokinetic effect of LC stimulation. The effect of stimulation of each nucleus was abolished by surgical severing of the parasympathetic pelvic nerves. Our findings demonstrate that activation of descending noradrenergic neurons from the LC and descending dopaminergic neurons from the A11 region causes enhancement of colorectal motility via the lumbosacral defecation center. The present study provides a novel concept that the brainstem monoaminergic nuclei play a role as supraspinal defecation centers. NEW & NOTEWORTHY The present study demonstrates that electrical and chemical stimulations of the locus coeruleus or A11 region augment contractions of the colorectum. The effects of locus coeruleus and A11 stimulations on colorectal motility are due to activation of α1-adrenoceptors and D2-like dopamine receptors in the lumbosacral defecation center, respectively. The present study provides a novel concept that the brainstem monoaminergic nuclei play a role as supraspinal defecation centers.

Abstract:
The burden of non-specific low back pain in the population is substantial. Putative sacroiliac joint pain or 'sacroiliac syndrome' is a significant subset of this condition. Localisable pain over the long posterior sacroiliac ligament (LPSL) is often described as both a clinical sign and symptom of this syndrome. The aim of this qualitative morphological investigation was to investigate a potential basis for a patho-anatomic relationship between the long posterior sacroiliac ligament (LPSL) and the posterior sacrococcygeal plexus (PSP). Twenty-two cadavers were available for study. Three methods were utilised: macro-dissection (n = 22 sides), small wax block histology (n = 3 sides), large wax block histology (n = 1 side), giant wax block histology (n = 4 sides) and a review of E12 sheet plastinated transverse and sagittal sections (n = 4 sides). The LPSL was demonstrated to have a layered structure that was penetrated by the lateral branches of the dorsal sacral rami. A segmental relationship was observed between the lateral branches of the dorsal sacral rami and the LPSL. The posterior layer of the thoracolumbar fascia was not continuous with the superficial layer of the LPSL, deep to the fibres of gluteus maximus. The LPSL was shown to have three morphologically distinct regions, the proximal, mid and distal LPSL. A confluence of three layers was observed at the mid LPSL posterior to the sacroiliac joint (SIJ) namely the erectores spinae aponeurosis (ESA), the gluteal aponeurosis (GA) and the deep fascial layer from the second and third medial dorsal sacral foramina. A region of adipose and loose connective tissue was evident deep to the deep fascial layer in which lateral branches of the dorsal sacral rami were observed. In the region of the mid LPSL between the inferior PSIS and the third sacral transverse tubercle (ST), the attachment of the ESA to sacral bone was absent. This space was occupied by the continuous underlying region of adipose and loose connective tissue. At its greatest extent, this region was observed between the central sacral canal medially and the gluteal aponeurosis laterally. This study suggests that the LPSL may be better described as a retinaculum for the lateral branches of the dorsal sacral rami. These morphological findings provide a basis for the existence of a potential patho-anatomical mechanism that may explain localised pain in the posterior sacroiliac region, usually interpreted as referred pain from the sacroiliac joint. The lateral branches of the dorsal sacral rami may have a potential vulnerability to trauma or ischaemic challenge in this region, which may account for SIJ related 'non-specific' low back pain or for pregnancy related peripartum pelvic pain. Furthermore, a morphological basis for the anatomical confounding of SIJ tests is shown.

Abstract:
The purpose of this study was to investigate the differences in muscle activity of the lumbar and pelvic extensor muscles during the hyperextension and reverse hyperextension exercises. Fifteen healthy and weight-trained volunteers (8 women, 7 men) were recruited from a university setting. Electromyographic (EMG) activity of selected hip and trunk extensor muscles was recorded during the execution of a hyperextension and a reverse hyperextension. Three muscles were analyzed: lumbar erector spinae (ES), biceps femoris (BF) and gluteus maximus (GM). The amount of external load used by each individual was determined by equating the amount of torque produced at the hip joint for both exercises. Participants performed two trials of each exercise, and completed at least three repetitions within the eight-second data collection period. Peak integrated EMG (iEMG) activity was expressed as a percentage of maximal voluntary isometric contraction (%MVC). A two-way repeated measures analysis of variance (ANOVA) failed to demonstrate significant differences in %MVC activity between the two exercises, (p>0.05). A comparison of the hyperextension and reverse hyperextension exercises revealed that under similar loading conditions, there is no significant difference in muscle activity of the lumbar and hip extensor muscles.

Abstract:
Radiography is a common radiologic investigation despite abundant evidence of its limited diagnostic value. On the other hand, computed tomography (CT) has a high diagnostic value and is widely considered to be among the most important advances in medicine. However, CT exposes patients to a higher radiation dose and it might therefore not be acceptable simply to replace radiography with CT, despite the powerful diagnostic value of this technique. At the expense of reduced CT image quality, which could be adjusted to the diagnostic needs, low-dose CT of abdomen and lumbar spine can be performed at similar dose to radiography. The aim of the current thesis project was to evaluate low-dose CT of the abdomen and lumbar spine and to compare it with radiography. The hypothesis was that CT would give better image quality and diagnostic information compared to radiography at similar dose levels. Firstly, the diagnostic accuracy of low-dose CT of the abdomen was evaluated. Results showed that low-dose CT of abdomen has a high sensitivity and specificity compared to radiography, i.e., it has higher diagnostic accuracy. Similar results were obtained from our systematic review. Secondly, in a phantom study, an ovine phantom was scanned at various CT settings. The image quality was evaluated to obtain a protocol for the optimal settings for low-dose CT of lumbar spine at 1 mSv. This new protocol was then used in a clinical study to assess the image quality of low-dose CT of the lumbar spine and compare it to radiography. Results showed that low-dose CT has significantly better image quality than radiography. Finally, the impact of Iterative reconstruction (IR) on image quality of lumbar spine CT was tested. Iterative reconstruction is a recent CT technique aimed to reduce radiation dose and/or improve image quality. The results showed that the use of medium strength IR levels in the reconstruction of CT image improves image quality compared to filtered back projection. In conclusion, low-dose CT of the abdomen and lumbar spine, at about 1 mSv, has better image quality and gives diagnostic information compared to radiography at similar dose levels and it could therefore replace radiography.

Abstract:
Abstract Draw A Cross-Section through the spinal cord; it is ovoid and has a thin fissure on its anterior side. The internal gray matter resembles a butterfly (or a bikini-top). Label the top of the diagram as “posterior” and the bottom as “anterior.” The ratio of gray matter to white matter varies throughout the rostro–caudal length of the spinal cord. In the lumbosacral spinal cord, the gray matter outsizes the white matter, whereas in the thoracic spinal cord, the white matter outsizes the gray matter. Why is this? At the bottom of the spinal cord, the ascending white matter tracts are narrow (they are just beginning to coalesce) and the descending white matter motor fibers have, for the most part, already terminated within the spinal cord gray matter, so they are also narrow. Conversely, in the thoracic cord, a high density of white matter lumbosacral afferent sensory fibers have accumulated and the white matter motor efferent bundles destined for the lumbosacral cord are still dense with fibers. Additionally, there are gray matter enlargements in both the lumbosacral and cervical spinal cord regions because of the high density of sensory and motor neurons required to innervate the distal extremities, which helps enlarge the relative size of the gray matter at those levels. But in the thoracic spinal cord, the gray matter size is small. Thoracic-innervated abdominal musculature requires less eloquent wiring than the lumbosacral-innervated footwork requisite for dancing or the cervical-innervated finger coordination required to play the piano. Thus, in the lumbosacral cord, the gray matter clearly outsizes the white matter and in the thoracic spinal cord, the white matter outsizes the gray matter. In the cervical spinal cord, both the gray and white matter are plump for reasons you can infer from the prior discussion.

Abstract:
Context: Elsberg Syndrome (ES) is a rare syndrome associated with acute or subacute infections, often accompanied by myelitis confined to the lower spinal cord, in addition to paresthesia, weakness in the lower limbs, urinary retention, constipation, among others. It is a self-limiting disease, manifested through primary HSV type 2 infection, especially in immunocompetent patients. Case report: Male patient J.F.C., 58 years old, reports a sudden paresthesia in the lower limbs without other associated clinical conditions for approximately 2 months that progressed to paresis, cramps and loss of sphincter control. Admitted to the General Hospital of Palmas, Tocantins on 02/18/2020 with suspicion of Peripheral Polyneuropathy that was discarded after electroneuromyography. Imaging exams without relevant findings. After a week of hospitalization, multiple lesions appeared in the region of the lower third of the dorsum and buttocks, compatible with lesions by HSV (herpes simplex virus) and the diagnosis of ES was concluded. At the moment, he was undergoing treatment with acyclovir and awaiting the evolution of the condition. Conclusion: ES is an often unrecognized cause of lumbosacral radiculitis, which is why it is important to establish as a diagnosis differential. The analysis of CSF, PCR and MRI confirm the diagnosis in cases of HSV-2 lumbosacral radiculomyelitis. CSF usually reveals a lymphocytic pleocytosis and a slight elevation of proteins.

Abstract:
Spondylitis is a very common back and neck ailment that is reported to account for one-third of social problems causing difficulty at work. It is caused due to the inflammation in vertebral joints. Its condition goes undetected until the symptoms, such as that of severe pain, develops. It causes stinging pain which is focused around cervical region of vertebra, the shoulders and the lumbar region of the spine. Accordingly, it is classified into three types: cervical, thoracic and lumbosacral spondylosis. This is different from spondylitis which causes pain due to inflammation. Many existing devices use electric current to bring relief from pain. Transcutaneous electrical nerve stimulation (TENS) is one of the most commonly used devices in this aspect. However, though this has been able to bring effective results to its patients, there is a whole lot of controversy in conditions it should be used to treat. Studies have shown these devices to bring relief by suppressing the signals from the brain. They are not advised for patients with pacemakers or any kind of electronically powered implantable devices. They are less effective where the skin is numb or in places where there is decreased sensation. It depends entirely on the working of the nerve beneath the surface and may cause irritation on the skin if the current is too high. Moreover, these devices need to be avoided in area where infection is present. High precaution needs to be taken when working with epilepsy patients and pregnant women; the electrical stimulation can interfere with the fetus development. With such a wide range of drawbacks, there is a need for a mechanical solution which can redress these problems and provide an effective and ergonomic solution. Along with overcoming the present barriers, research has been done to demonstrate the positive effects of vibration in increase of bone density, increase of muscle mass, increase of blood circulation, reduced back pain, reduced joint pain and boost in metabolism. The given paper discusses a device wherein vibrational motors have been incorporated, under the control of a microcontroller, to generate the requisite g-force needed for the purpose of pain alleviation and increase of bone density.

Abstract:
In this paper, A new biodynamical model was developed with the objective of analyzing the dynamic responses of the human back during the exertion of symmetric lifting activities. More emphasis was placed on the study of the lumbosacral disc located between the fifth lumbar and first sacral vertebrae (L5/S1). The present model accounts for the sliding components of velocity and acceleration as well as the Coriolis acceleration in the kinematical equations of the human back. The inclusion of those terms has enabled a more accurate computation of the generated sliding effect of the flexible disc as well as the change in its height and width which normally occurs during the gross body rotation of the back. This has turned to have a significant effect on the resulting compressive force applied at the L5/S1 region. A computer model was developed in this study to automate the biodynamical simulation processes for workers of different genders and for a vast range of body postures. Results indicated that the inclusion of the sliding components of velocity and acceleration do actually have a significant effect on the whole range of lifting activities in which an angular velocity exceeding 24 degree/sec is employed. Results obtained in this paper were compared with the experimental and computational (simulated) results of recent relevant publications. The comparison shows that there are good agreements between the results for angular velocities exceeding 24 degree/second, which is known as the normal range of operation in lifting activities. Results obtained in this paper were in good agreement with NIOSH action and maximum limits which make it reliable for use as a guideline to help workers in industry to avoid hostile lifting activities and bring to attention an early warning to avoid engaging industrial labors with postures leading to severe back pain problems.

Abstract:
Context: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease, characterized by progressive muscle weakness. The diagnosis is not always easy, and may have atypical initial manifestations. Case report: O.S.M, female, 62 years old, started in 2016 with bradykinesia and left lower limb tremor, associated with frequent falls. Iniciated research for parkinsonism in 2017, SPECT demonstrated decreased dopamine transporter binding potential density in both striatum. Levodopa was started, with partial improvement of symptoms. In 2018, she developed dysphagia, associated with slight alterations in phonation. In 2019, in addition to the left lower limb tremor and bradykinesia, the patient developed limb paresis, also affecting the right upper limb, with proximal atrophy and fasciculations. Added to the therapeutic regimen pramipexole, without improvement in symptoms. Over the months the case progressed with axial weakness, the need for a wheelchair for walking. Patient hospitalized in April 2020, electroneuromyography performed which showed signs of active disinvervation in the bulbar, cervical, thoracic and lumbosacral segments and signs of chronic disinervation in the cervical and lumbosacral segments, with no signs of sensory or motor polyneuropathy. Such findings suggest impairment of the Lower motor neuron, and can be found in the Diseases of the Motor Neuron. With the diagnosis of ALS, Riluzole was started, with a reduction in the speed of disease progression. Conclusions: the reported case draws attention to the importance of always thinking about differential diagnoses in neurological diseases. We should always look for new symptoms, so that more rare diseases do not go unnoticed.

Abstract:
The vertebral endplates of the lumbosacral spine have various degrees of concavity and/or convexity. Several investigators including Seenivasan G., Goel, V. K., 1994, Liebschner et al, 2003, etc have performed finite element analysis on the vertebral bones, but the endplate curvatures are not included. Therefore, the effect of morphological details of the endplate curvatures on the stress distribution is unknown. Differences in these curvatures will increase stress in some regions and decrease stress elsewhere as the spine is compressed. In our previous study [Kale et al, 2003], lumbar vertebral endplate curvatures in the anterior-posterior and medial-lateral directions on human cadaver lumbar vertebrae were measured. The measurements were carried out using a reverse engineering instrument, built at Rutgers University [Hsieh et al, 2002]. Six sets of measurements (on human male-female L4 lower to S1 upper endplates) were performed. The data was later used in a linear elastic cylindrical model containing cortical shell and trabecular core. The model then was modified to a more accurate model, with more realistic, characteristic kidney shaped cross section (obtained from equation by Mizrahi et al, 1993) and linearly varying height. The endplates were assigned curvatures extracted from our human cadaver data. FEA, done on both the models, showed that the endplate curvatures and their location had significant effect on the stress distribution in the vertebral bone. In the current study we have extended our bone model into a motion segment and have investigated the effects of the curvatures on the stresses in the motion segment.
