Toxoplasmosis in an immunocompetent patient

Toxoplasmosis is an obligate intracellular, food borne parasite disease with variable clinical presentation. Although the neurological presentation of toxoplasmosis in immunocompetent patients is uncommon, broad differential diagnosis should be kept in consideration when attending to similar patients. Twenty years old man with no known co-morbid conditions presented with fever and unilateral limb weakness for three weeks. It increased gradually, associated with altered level of consciousness for the last five days, diagnosed as acute toxoplasmosis. MRI Brain showed multiple ring enhancing lesions in frontal, parietal and temporal lobes. Serology for toxoplasmosis denoted raised IgM levels 36IU/mL [cut off value > 18IU/ mL]. This case report describes the clinical presentation and management of neurological toxoplasmosis in immunocompetent patient. Early diagnosis and prompt management can resolve the symptoms at an earlier stage

Multidisciplinary team [MDT] meeting and Radiologist workload: a prospective review in a tertiary care hospital

Objective: To quantify the increase in workload associated with multidisciplinary team meetings for radiologists in a tertiary care hospital over a period of 15 months

Methods: Data was collected prospectively regarding number of multidisciplinary team meetings, number of clinical cases discussed, number of individual imaging studies reviewed, and preparation time of residents, senior registrar and consultants and the delivery time of meeting

Results: Total 223 meetings were held over 15 months [April 2014 to June 2015] for 12 clinical specialty areas. There were 1120 clinical case discussions and a total of 2759 documented individual imaging studies reviewed. Resident's preparation time was 74.6 hours/month, senior registrar's preparation time was 47.93 hours/month, consultant's preparation time was 18.67 hours/month and the total duration time for meetings was 18 hours/month

Conclusion: Multidisciplinary team meetings now represent a significant workload of radiology and has reduced the time for other academic activities within the department

Magnetic Resonance Imaging in Cervical Facet Dislocation: A Third World Perspective

STUDY DESIGN: Retrospective case series. PURPOSE: The objective of our study was to determine the change in management brought about by magnetic resonance imaging (MRI) of the cervical spine in alert and awake patients with facet dislocation and spinal cord injury presenting within 4 hours after injury. OVERVIEW OF LITERATURE: Spinal cord injury is a common clinical entity. The role of MRI is well established in evaluating spinal trauma. However, the time at which MRI should be used is still controversial. METHODS: Retrospective data from 2002-2010 was evaluated. All of the alert and awake patients with spinal cord injury, based on clinical examination with facet dislocation diagnosed on lateral cervical spine X-rays, were included. A questionnaire was also conducted, the data of which consisted of demographic details including age and sex, the mechanism of injury, clinical examination, X-ray findings, MRI findings, whether or not surgery was performed and the time elapsed since injury. Data was analyzed using SPSS ver. 17.0. Continuous variables such as age were expressed in terms of mean +/- standard deviation. Categorical variables such as change in management, X-ray/MRI findings and neurological motor level were assessed in terms of percentage. RESULTS: Fifty patients participated in our study. All these patients had spinal cord injury with defined motor levels. The mean age was 35.5 +/- 8.95 years (range, 20 to 52 years). Fifty percent showed a motor level at C6 level. None of the patients required any change in management based on the MRI. CONCLUSIONS: MRI of the spine in awake patients within 4 hours after injury does not change the management of patients. However, we can hypothesize that such patients can proceed to traction without waiting for the MRI.

Flexion/extension cervical spine views in blunt cervical trauma / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To examine the contribution of flexion and extension radiographs in the evaluation of ligamentous injury in awake adults with acute blunt cervical spine trauma, who show loss of cervical lordosis and neck pain.</p><p><b>METHODS</b>All patients who presented to our emergency department following blunt trauma were enrolled in this study, except those with schiwora, neurological deficits or fracture demonstrated on cross-table cervical spine X-rays, and those who were either obtunded or presented after cervical spine surgery. Adequacy of flexion and extension views was checked by the neurosurgery and radiology team members. All these patients underwent cross-table cervical spine view followed by flexion/extension views based on the loss of lordosis on cross-table imaging and the presence of neck pain.</p><p><b>RESULTS</b>A total of 200 cases were reviewed, of whom 90 (45%) underwent repeat X-rays because of either inadequate exposure or limited motion. None of the patients with loss of lordosis on cross-table view had positive flexion and extension views of cervical spine for instability.</p><p><b>CONCLUSIONS</b>Our results show that in patients who underwent acute radiographic evaluation of blunt cervical spine trauma, flexion and extension views of the cervical spine are unlikely to yield positive results in the presence of axial neck pain and/or loss of cervical lordosis. We can also hypothesize that performing flexion and extension views will be more useful once the acute neck pain has settled.</p>

Repeat cranial tomography in patients with mild head injury and stable neurological examination ---- a perspective from a developing country / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To determine the frequency of altered findings on repeat cranial tomography (CT) in patients with mild head injury along with stable neurological examination at tertiary care hospital.</p><p><b>METHODS</b>Cross-sectional study was done in the Department of Radiology, Liaquat National Hospital, Karachi from January 2008 to September 2010. All patients with mild head injury in terms of Glasgow Coma Scale (GCS) who underwent repeat scan without clinical or neurological deterioration in the emergency department of a tertiary care centre were included. The collected data were accordingly entered and analyzed by the principal investigator using Statistical Package for Social Sciences (SPSS) version 16.0.</p><p><b>RESULTS</b>In all 275 patients, only 17 (6%) of the patients were found worseing on repeat CT, 120 (43.63%) scans improved, 138 (50.18%) unchanged and 17 (6.18%) worsened. None of these patients showed signs of clinical deterioration.</p><p><b>CONCLUSION</b>Our results suggest that for patients with mild head injury and stable neurological examination, only 6% of them show deterioration on repeat CT, especially when patients'GCS is below 13.</p>

Variations in Practice Patterns among Neurosurgeons and Orthopaedic Surgeons in the Management of Spinal Disorders

STUDY DESIGN: This is a case series. PURPOSE: We wanted to identify variations in the practice patterns among neurosurgeons and orthopedic surgeons for the management of spinal disorders. OVERVIEW OF LITERATURE: Spinal disorders are common in the clinical practice of both neurosurgeons and orthopedic surgeons. It has been observed that despite the availability of various guidelines, there is lack of consensus among surgeons about the management of various disorders. METHODS: A questionnaire was distributed, either directly or via e-mail, to the both the neurosurgeons and orthopedic surgeons who worked at 5 tertiary care centers within a single region of Korea. The surgeons were working either in private practice or in academic institutions. The details of the questionnaire included demographic details and the specialty (orthopedic/neurosurgeon). The surgeons were classified according to the level of experience as up to 5 years, 6-10 years and > 10 years. Questions were asked about the approach to lumbar discectomy (fragmentectomy or aggressive disc removal), using steroids for treating discitis, the fusion preference for spondylolisthesis, the role of an orthosis after fusion, the preferred surgical approach for spinal stenosis, the operative approach for spinal trauma (early within 72 hours or late > 72 hours) and the role of surgery in complete spinal cord injury. The data was analyzed using SPSS ver 16. p-values < 0.05 were considered to be significant. RESULTS: Of the 30 surgeons who completed the questionnaire, 20 were neurosurgeons and 10 were orthopedic surgeons. Statistically significant differences were observed for the management of spinal stenosis, spondylolisthesis, using an orthosis after fusion, the type of lumbar discectomy and the value of surgical intervention after complete spinal cord injury. CONCLUSIONS: Our results suggest that there continues to exist a statistically significant lack of consensus among neurosurgeons and orthopedic spine surgeons when considering using an orthosis after fusion, the type of discectomy and the value of intervention after complete spinal injury.
