Posterior Reversible Encephalopathy Syndrome in the Setting of Uncontrolled Hypertension and Diabetes Mellitus

Truth and Responsibility
“Truth and Responsibility” is a call to reimagine anthropology to meet the demands of the present moment. The imperative to bear witness, take action, and be held accountable to the truths we write and circulate invites us to reflect on our responsibility in reckoning with disciplinary histories, harms, and possibilities. To whom are we giving evidence and toward what ends? For whom are we writing? To whom are we accountable, and in what ways? We are thrilled to announce the theme of the 2021 AAA Annual Meeting to be held in Baltimore, MD: Truth and Responsibility.

Many consider anthropology to be a holistic social science dedicated to cross-cultural understanding as a way to reduce bigotry and more fully comprehend “what it means to be human.” Others push against this readily circulated origin story, arguing that “human” remains a highly contested, political category—evident as the presumed set of rights and protections associated with the “human” continue to be stripped away violently in the communities in which some of us live and work. Which violent histories and epistemologies must anthropologists take responsibility for in telling truth(s) about the discipline’s development? How do the dual histories of settler colonialism and slavery continue to influence anthropological thought and practices? In these political times, how can anthropologists throughout the globe work to secure a capacious, progressive vision of the human? How might movements for anti-racism, decoloniality, queer liberation, and healing such as #BlackLivesMatter, #ProtectMaunaKea, and #MeToo push a future anthropology out of the ashes of the anthropological past? Finally, what are the limits and possibilities of the anthropological imagination?

Across subfields, we find truths in patterns of human behavior, language, evolution, and cultural worlds. Industry-positioned anthropologists do this by extending the boundaries of the discipline not as an administrative solution to job shortages but as a source of intervention and knowledge production. Increasingly, anthropologists who make use of the scientific method question how status and identity help to decide which facts come to represent truth. How might quantitative researchers use our methods to identify patterned truths, and what responsibility do we hold in challenging conventional wisdom about these patterns? What responsibility do we have to both our colleagues and larger publics, to push toward increased transparency and ethical grounding in our data collection, analysis, and presentation?

Pedagogy is a key medium for the communication of anthropological truths. Which (and whose) truths are foregrounded in our curricula? What are the possibilities for a liberatory pedagogy in a precarious, “post-truth” era? Conferences, museums, organizing spaces, and classrooms are sites where pedagogy and various forms of communication can help us interrogate the performativity of truth. How might anthropologists conceive of truth performances? Might visual, aural, and choreographic performances during AAA sessions offer anthropologists alternative genres for truth-telling and truth-making that provoke discussions about responsibility?

In accordance with the urgency of the year’s theme, the questions posed in this call for papers do not have easy answers. The hope is that those who submit proposals will take up these questions and engage in collective thinking and imagining about the truths we hold, the truths we challenge, and the responsibilities we bear in co-creating a free and more equitable world. All panel proposals should have a statement about how the panel has incorporated the goals of equity, diversity, and inclusion, and/or analysis of power.

Executive Session proposals have already been selected and speak directly to the theme “Truth and Responsibility.” To practice the critical reflexivity this call for papers invites, we asked that Executive Session submissions explicitly address the diversity of session participants, such as organizational/institutional affiliation, career stage, race, ethnicity, disability, sexuality, class, religion, national identity, and gender. Proposals for Executive Sessions that demonstrated a commitment to equity and inclusion and/or a clear analysis of power (i.e. anti-imperialist, anti-white supremacist, decolonial, anti-ableist, feminist, anti-transphobic, anti-xenophobic, etc) were given priority. We are excited to be in conversation with residents of the Baltimore region and look forward to the discussions, performances, and actions generated by the dynamic group of anthropologists attending the 2021 AAA Annual Meeting.

Role of Shoulder Injury Related to Vaccine Administration (SIRVA) in the COVID-19 Pandemic

Septic arthritis of the TMJ is a rare bacterial infection of the joint space, with a reported incidence of 2 to 10 cases per 100,000 patients. Its uncommonness in the clinical setting has led to a corresponding scarcity in the literature, and as a result, SATMJ has no definitive management guidelines in place. Owing to dangerous sequelae including abscess formation or total joint destruction, it is all the more essential to provide rapid therapeutic intervention. Here we present a case of a patient with a history of chronic mastoiditis and otitis media as well as skull base osteomyelitis, who presented with symptoms concerning for SATMJ. Our patient was a 62-year-old male who presented from a nursing facility with one week of progressive left-sided facial swelling and pain. Though the patient was afebrile and had a normal white blood cell count, CT imaging of the maxillofacial bones showed erosive changes at the left TMJ, most consistent with septic arthritis, and an adjacent multilocular abscess. The patient was placed on empiric vancomycin and zosyn; drainage of the abscess by ENT yielded 2 mL of purulent fluid, though culture was negative. The patient’s pain and swelling subsequently improved, and he was discharged with a four-week course of daptomycin and cefepime. Common etiologic factors in SATMJ include contiguous spread from nearby infectious sources. Our patient’s triad of oromaxillofacial pathologies appears to be unique in the literature, and further reflects the role that local infection can play in seeding the joint. Staphylococcus aureus is the most common offending organism, with Neisseria and H. flu also isolated on occasion. However, due to the prompt initiation of antibiotics in presenting patients, joint aspirate is often found to be sterile. Owing to the ambiguity of presenting symptoms and laboratory values, imaging via CT or MRI is considered the most accurate method of diagnosis. Treatment of SATMJ is accomplished through dual therapy of proper antibiotic coverage and drainage of the joint space. As seen in our patient, rapid detection and an equally timely treatment of his condition resulted in a positive clinical course and a successful outcome.

Septic Arthritis of the TMJ in the Setting of Mastoiditis, Otitis Media and Skull Base Osteomyelitis

Introduction:
Spinal stenosis is the narrowing of intervertebral foramina most commonly caused by degenerative changes in the vertebral bodies. Other common causes include achondroplasia, ankylosing spondylitis, or Paget disease. We report a case of a 32-year-old male who presented with difficulty walking and was found to have a rare culprit, spinal epidural lipomatosis (SEL).

Case Description:
A 32-year-old obese male presented with an eight-month history of progressive bilateral leg weakness and back pain, with acute worsening in the past two weeks. He also had associated bilateral lower extremity pain, weakness, numbness, and multiple mechanical falls in the past six months. On physical exam, he was afebrile and normotensive with BMI of 38. He was A/A/O x 4, with neurologic exam significant for muscle strength 2/5 in left leg, 3/5 in right leg, and 5/5 in bilateral upper extremities. He had diminished sensation below L3 in both legs, +4 bilateral patellar reflex with clonus, and upgoing bilateral plantar reflexes. Labs showed normal levels of cholesterol, triglycerides, hbA1C, and TSH. MRI thoracic and lumbar spine revealed spinal cord stenosis with cord compression and myelopathy at T5-T6 due to left central disc extrusion, thickening of ligamentum flavum, and diffuse dorsal epidural lipomatosis. Neurosurgery was consulted, and he underwent urgent T5-T6 decompressive laminectomy with partial T4-T7 laminectomies for evacuation of epidural lipomatosis. At the time of discharge to a rehabilitation facility, his weakness improved in lower extremities with 4/5 muscle strength bilaterally. 

Discussion:
Spinal epidural lipomatosis is seen in 2.5% of population and is caused by excessive adipose tissue in the epidural space. The exogenous steroid group represents 55.3% cases, while obesity-associated disease represents 24.5%. In our patient, obesity may be a driving factor for SEL. SEL is most common in patients taking exogenous steroids, such as post-transplant patients. SEL is also seen in people with type 2 diabetes mellitus, increased production of endogenous steroids, HIV on protease inhibitor therapy, Scheuermann's disease, and those on androgen antagonist therapy. 
Management of SEL depends on the presentation. With acute neurologic deficits, the first-line treatment is urgent surgical decompression. Conservative management of inciting features is recommended if there is a slowly progressive disease. It includes cessation of steroids and treatment of endocrinopathies. Weight reduction has been shown to significantly reduce SEL in obese patients, with one report recommending at least 15 kgs of weight loss to help control symptoms. If conservative therapy is not successful, decompressive surgery such as laminectomy with or without removal of fatty tissue can be considered. Removing as much fatty tissue as possible avoids post-surgical complications. Unfortunately, mortality rate within one year after surgical decompression is as high as 22%.

INTRODUCTION:

Gastrointestinal (GI) manifestations are most frequently reported extra-pulmonary symptoms of COVID-19 infection with a prevalence of 10%-50%. Most common are nausea, vomiting, diarrhea, and abdominal pain. GI perforation especially spontaneous colonic perforations are rare in the disease course.


METHODS:

We report a patient with COVID-19 infection, who developed cecal perforation while recovering from COVID pneumonia, necessitating emergent surgical treatment, and the current literature was reviewed.
65-year-old male presented with shortness of breath, myalgias and fever. He was admitted to ICU secondary to acute hypoxemic respiratory failure due to COVID 19 pneumonia. He was treated with steroids, tocilizumab and remdesivir. On day-11, he developed severe abdominal pain with worsening leukocytosis. His imaging showed large pneumoperitoneum, suggestive of a perforated viscus. He underwent emergent laparotomy and was found to have non-obstructive cecal perforation. A colonic de-tension and right colectomy with ileo-transverse anastomosis was performed. The tissue pathology showed distended colon, active colitis, transmural granulocytic inflammation, and ulceration suggesting bowel perforation.


RESULTS:

ACE2 protein, a cell receptor for SARS-CoV-2, is in glandular cells of gastrointestinal epithelia. Direct viral infection, small vessel thrombosis, or nonocclusive mesenteric ischemia can cause spectrum of bowel findings. SARS-CoV-2 can have direct inflammatory effect on vascular endothelium too. Use of steroids, tocilizumab and systemic coagulopathy seen in severe COVID-19 infection also contributes to these manifestations. In our patient, an acute over-distension of colon, without mechanical distal obstruction, in the setting of COVID-19 infection & tocilizumab led to cecal perforation. Our literature review confirmed only 33 case-studies of bowel perforation in the setting of COVID-19 infection have been reported, with combined 28.5% mortality rate. Considering the worldwide incidence of this pandemic, it is a rare complication.


CONCLUSIONS:

GI perforation is a rare but dangerous complication of COVID-19. Treatment with interleukin-6 inhibitors or steroids is often associated in most cases. Our case underlines the need to be vigilant for severe GI symptoms in setting of COVID-19 infection to improve patients’ outcome.


Spontaneous Colonic Perforation as an unusual presentation of COVID-19 infection: Case Report and Review of literature

Background: Familial Mediterranean fever (FMF) is a rare autosomal recessive, autoinflammatory disease that causes recurrent attacks of fever and acute inflammation in the body. Here we have a case of a clinically diagnosed FMF pt who has a monoallelic mutation of the MEFV gene. This case is unique as the specific monoallelic mutation found has not been reported to cause FMF on its own.

Case Presentation: 13 yo male presents with 2-year history of frequent fever occurring 2-4 times per week accompanied with feeling unwell. Fevers range from 100.5-101 F, resolve with Tylenol, and can occur with sore throat and abdominal pain. No chest pain, joint pain, or rashes present. Genetic testing and evaluation revealed pt is a heterozygous carrier of a pathogenic variant in the MEFV gene, c.2177T>C (p.Val726Ala). FHx of Ashkenazi Jewish ancestry and SLE on maternal side. Workup of UA, CRP/ESR, liver + BMP, and CBC were unremarkable. Diagnosed patient with FMF type I and started on colchicine trial of 0.9 mg daily which improved symptoms. Raised to 1.5 mg daily after pt tolerated trial and symptoms significantly improved. Clinical diagnosis for FMF based on Tel Hashomer Criteria and improvement of symptoms with colchicine trial.

Discussion: FMF is the most common of the known autoinflammatory diseases. The recessive gene for FMF, MEFV, is carried by Ashkenazi Jewish, Turkish, Arabian, Mediterranean, and Middle Eastern populations. This gene encodes pyrin, a protein thought to regulate inflammation through the IL-1 signaling pathway. Severe heterozygous mutations can sometimes cause FMF in a monoallelic form, but this patient’s specific mutation has previously not been found to cause FMF. This is a unique case which demonstrates a Val726Ala heterozygous mutation to cause clinically significant FMF. Also, this case provides an opportunity to demonstrate proper treatment for this patient presentation. 


A Unique Monoallelic Presentation of Familial Mediterranean Fever

We present a 48yr old male, who presented with left flank pain
and imaging findings of bladder stone and severe right-sided hydroureteronephrosis, found to have left- sided emphysematous pyelonephritis, with bladder stone and severe rightsided hydroureteronephrosis. He initially received bilateral nephrostomy tubes, left- sided perinephric draining tube, and IV antibiotics: however, symptoms persisted. Ultimately, patient underwent left nephrectomy and open cystolitholapaxy with eventual resolution of symptoms.

Background
Leptomeningeal disease (LMD) is a late stage sequela to a number of malignant cancers including non-small cell lung cancer, melanoma, and breast cancer. Advances in chemotherapy, immunotherapy and targeted therapy have extended overall survival, but have also brought on an increase incidence of LMD. LMD is often associated with communicating hydrocephalus and elevated intracranial pressure due to disruption of cerebrospinal fluid (CSF) absorption. If left untreated, hydrocephalus can be fatal.

Case Presentation
We report an 18-year-old female with a history significant for malignant melanoma presenting with headaches, nausea, and vomiting three months after a craniotomy for metastatic melanoma in the temporal lobe with extension into the lateral ventricle. Ventriculomegaly apparent on brain MRI led to a diagnosis of communicating hydrocephalus, necessitating placement of a ventriculoperitoneal shunt. The shunt was placed without difficulties or complications, and postoperative CT scan demonstrated no ventricular catheter-associated blood. Following a brief
period of improved mental status and alertness, the patient rapidly deteriorated and expired in the six hours following shunt placement due to a diffuse subarachnoid hemorrhage.

Discussion
Communicating hydrocephalus secondary to leptomeningeal disease affects a high percentage of patients with leptomeningeal metastases and is routinely treated with ventriculoperitoneal shunting. Common risks of shunting include intraventricular hemorrhage or intraparenchymal hemorrhage along the catheter tract, as opposed to subarachnoid hemorrhage observed in the present case. Subarachnoid hemorrhage is also an exceedingly rare complication of leptomeningeal disease. The underlying mechanism to the observed subarachnoid hemorrhage is suspected to be related to the diseased state of the vessels within the leptomeninges and the rapid decrease in intracranial pressure from shunt placement. This case brings to light a unique complication that necessitates future consideration to determine incidence, etiology, and risks to patient treatment.

Abstract Title: Idiopathic Spinal Cord Herniation: A Case Report

Background: Idiopathic Spinal Cord Herniation (ISCH) is a rare condition in which the spinal cord protrudes through an opening in the ventral dura mater of the spinal canal. It is most commonly seen in the thoracic spine and presents as a slowly progressive myelopathy and Brown-Sequard syndrome in 65% of patients. Literature on ISCH consists of fewer than 200 cases and misdiagnosis as posterior arachnoid cyst is believed to be common. Fortunately, advances in medical imaging as well as case reports like this one, are expanding our understanding of ISCH presentation and treatment. 

Case Presentation: A 53 y/o male presented with a four-year history of slowly progressive myelopathy and Brown-Sequard syndrome. MRI imaging was performed but was found inconclusive. Due to challenges in establishing a definitive pre-operative diagnosis, exploratory surgery was performed which identified an opening in ventral dura, and herniation of the spinal cord at the level of T7-T8. Laminectomy and durotomy were performed which allowed access to the spinal cord. The cord was relaxed and brought back into proper alignment within the spinal canal. The ventral opening was then successfully closed with a Duraseal patch. Upon follow up, our patient experienced near full relief of motor and sensory symptoms.

Discussion: Idiopathic spinal cord herniation develops most exclusively at the thoracic level and most commonly in middle-aged women. Herniation of the spinal cord through the dura compresses the cord and leads to a wide range of symptoms – varying from mild motor-sensory deficits to Brown-Sequard syndrome. ISCH has previously been misdiagnosed as posterior arachnoid cyst, which causes a similar presentation due to compression of the ventral cord and nerve roots. Therefore, sagittal contrast MRI and CT myelogram is indicated. Multiple mechanisms of ISCH have been proposed, including developmental disorders, thoracic disc herniation, and history of trauma. Relative scarcity of elastic connective tissue in the ventral dura mater is a proposed contributive factor. As awareness grows and imaging technology improves, accurate diagnosis of ISCH is becoming increasingly possible. This diagnosis is crucial for proper surgical treatment and for optimal patient outcomes.

Idiopathic Spinal Cord Herniation: A Case Report

Large Retroperitoneal Paraspinal Schwannoma causing lumbar radiculopathy- a case report.

ABSTRACT

Background
Schwannoma is a benign, slow-growing nerve sheath tumor consisting of Schwann cells. It is generally located in the upper limb, head, trunk, and flexor surface of lower extremities. Retroperitoneal paraspinal schwannoma is relatively rare. Because of its slow-growing nature, it might be years before any symptoms or signs is observed. However, when there’s one, it usually depends on the tumor’s location, size, and mass effect. We present a case of paraspinal retroperitoneal Schwannoma in a 30-year-old male.

Case presentation 
30 years Asian male presented with a 10-year history of on and off, dull, left lower back and gluteal pain radiating to the lower leg. The patient denies any history of falls or trauma. On examination, motor and sensory exam was normal. The straight leg raise test was negative. Reflex was 3+ in all extremities. Denies any bowel, bladder, or sexual dysfunction. MRI lumbar spine showed a retroperitoneal, solitary, paraspinal mass in the left psoas muscle measuring 4.8 cm AP by 8.1 cm SI by 7.0 cm TV. An image-Guided Biopsy of the mass was performed. Histopathology showed specific Antoni A and Antoni B areas with verocay body, and immunochemistry was positive for S-100 and negative for CD 34 confirming the diagnosis of schwannoma.

Discussion
Retroperitoneal paraspinal schwannoma is relatively rare. Clinical features depend on the size, location, and mass effect of the tumor. It should be considered as one of the differentials for lumbar radiculopathy. MRI of the lumbar spine is the initial imaging study of choice. A definitive diagnosis is obtained by biopsy. Microscopically, it shows specific Antoni A and B areas with verocay bodies. Immunochemistry shows positive S-100 and negative CD 34. Surgical resection is the standard treatment, however, it is wise to closely observe young and/or asymptomatic patients with follow-up MRI. The decision to resect the tumor depends on the size, growth rate, mass effect, and symptoms. The rate of recurrence and malignant transformation is relatively low.

Large Retroperitoneal Paraspinal Schwannoma causing lumbar radiculopathy- a case report.

Background: Amyotrophic lateral sclerosis is a chronic neurodegeneration of the upper and lower motor neurons, and it is either spinal-onset or bulbar-onset. Here we present a case of bulbar-onset ALS with its many typical features.

Case Presentation: Patient is a 47-year-old female with a past medical history of diabetes mellitus, anxiety, depression, and GERD came to the ED complaining of increasing weakness in extremities, worsening unsteady gait, blurry vision, and right side of tongue heaviness. She denied headache, nausea, vomiting or diplopia. Physical exam was unremarkable on admission. MRI revealed pituitary adenoma. The patient was discharged to follow up with her ophthalmologist and endocrinologist. Patient came back to the ED three years later, complaining worsening depression symptoms and gait unsteadiness where she couldn’t walk unassisted. She also complained of progressive trouble breathing and speaking. Patient’s son reported that the patient had increasing mood liability for the past four months, with anger outburst and uncontrollable laughing and crying. She also couldn’t perform her ADLs. The brain MRI redemonstrated stable pituitary mass compressing optic chiasm. Physical exam was remarkable for dysarthria, spasticity was noted on bilateral lower extremities, first dorsal interosseous atrophy, positive left Hoffman’s reflex, and positive bilateral pectoralis reflex. Paraneoplastic panel was ordered, which came back negative two weeks later. Nuedexta was prescribed for her pseudobulbar affect (PBA) syndrome, and baclofen was prescribed for spasticity. Furthermore, the patient was diagnosed with bulbar-onset ALS, as EMG/NCS showed evidence of neuropathy. Patient was provided an order of power chair and non-invasive ventilator, and scheduled for a regular EMG/NCS monitoring lower motor neuron function.

Discussion: This case highlighted the typical progression of bulbar-onset ALS, consisting of dysarthria and emotional liability and it’s mostly common in women. Because of the patient’s history of depression, her PBA may be mistaken as related to her mood disorder. Her incidental finding of pituitary adenoma may have confounded the symptoms of blurry vision and muscle weakness. It also highlighted the challenge of ALS diagnosis as many other neurological conditions can mimic ALS, and the importance of physical exam findings which can lead to early suspicion of ALS.
