Emergency department management of acute agitation in the reproductive age female and pregnancy.

BACKGROUND: Agitation is a common presentation within emergent departments (EDs). Agitation during pregnancy should be treated as an obstetric emergency, as the distress may jeopardize both the patient and fetus. The safety of psychotropic medications in the reproductive age female has not been well established. This review aimed to explore a summary of general agitation recommendations with an emphasis on ED management of agitation during pregnancy. METHODS: A literature review was conducted to explore the pathophysiology of acute agitation and devise a preferred treatment plan for ED management of acute agitation in the reproductive age or pregnant female. RESULTS: While nonpharmacological management is preferred, ED visits for agitation often require medical management. Medication should be selected based on the etiology of agitation and the clinical setting to avoid major adverse effects. Adverse effects are common in pregnant females. For mild to moderate agitation in pregnancy, diphenhydramine is an effective sedating agent with minimal adverse effects. In moderate to severe agitation, high-potency typical psychotropics are preferred due to their neutral effects on hemodynamics. Haloperidol has become the most frequently utilized psychotropic for agitation during pregnancy. Second generation psychotropics are often utilized as second-line therapy, including risperidone. Benzodiazepines and ketamine have demonstrated adverse fetal outcomes. CONCLUSION: While randomized control studies cannot be ethically conducted on pregnant patients requiring sedation, animal models and epidemiologic studies have demonstrated the effects of psychotropic medication exposure in utero. As the fetal risk associated with multiple doses of psychotropic medications remains unknown, weighing the risks and benefits of each agent, while utilizing the lowest effective dose remains critical in the treatment of acute agitation within the EDs.

Spontaneous tumor lysis syndrome in a patient with chronic myeloid leukemia treated successfully with allopurinol.

BACKGROUND: Tumor Lysis Syndrome (TLS) is an oncologic emergency that may occur in any patient with a hematologic malignancy, even prior to initiation of chemotherapy. Spontaneous TLS massive tumor cell destruction with intracellular electrolyte release prior to the initiation of chemotherapy. Spontaneous tumor lysis syndrome is a rare presentation, mainly occurring in Acute Leukemia and non-Hodgkin Lymphoma. Chronic Myeloid Leukemia (CML) is a low-risk disease based on TLS risk stratification. To the best of our knowledge, spontaneous TLS in the chronic phase of CML successfully treated with allopurinol and aggressive hydration has yet to be reported in the literature. A case report is described regarding a 67 year old Jamaican female with a history of hypertension who presented to the emergency department with abdominal pain, nausea, and vomiting for 1 day. The patient was found to have leukocytosis to 344,000 with 4% Blasts, hyperuricemia, and acute kidney injury. A peripheral blood smear confirmed the diagnosis of CML. Bone marrow biopsy was performed with evidence of the chronic phase of CML. The patient met clinical criteria for spontaneous tumor lysis syndrome. The patient was started on aggressive intravenous hydration, allopurinol, hydroxyurea and imatinib. Creatinine and uric acid level improved on this regimen within 48 h of initiation.

Mixed connective tissue disease-myositis overlap syndrome presenting as an allergic disease process to the emergency department: A case report.

BACKGROUND: The "allergy epidemic" of the Western World, has led to an overwhelming number of emergency department presentations with allergic rhinitis, allergic conjunctivitis, atopic eczema, and asthma. Careful consideration should be given to screening for the typical signs and symptoms of Mixed connective tissue disease (MCTD) in patients presenting to the ED with what appears to be a simple allergic process. MCTD is a rare systemic rheumatic disease characterized by high levels of anti-U1RNP antibodies and various clinical signs and symptoms. The pathophysiology of MCTD is poorly understood. An association between allergen-mediated processes and MCTD has been reported in recent literature. Our case report involves a 40 year old African American female with initial outpatient presentation suggestive of atopic disease, with progressive worsening of symptoms while receiving allergen immunotherapy. The patient presented to the emergency department with bilateral leg cramping. The patient was found to have a CPK of 7000 unresponsive to fluids. The patient was evaluated by the Allergy and Rheumatology services. The patient was ultimately diagnosed with MCTD-Myositis Overlap Syndrome and started on steroids and IVIG with improvement in symptoms. While MCTD is not a diagnosis readily made in the ED, early identification and treatment of the disease is critical for prevention of long term complications.

Acute Cholecystitis: An Emerging Complication in Spinal Cord Injury Patients in the United States.

BACKGROUND: Spinal cord injury (SCI) is a significant medical condition associated with various secondary complications, including cholelithiasis. Cholelithiasis can cause biliary duct obstruction and result in acute cholecystitis. The development of acute cholecystitis in SCI patients has been well studied in the Taiwanese population, showing an increased risk of acute cholecystitis in patients with SCI. The development of cholecystitis has not been well studied in the United States. MATERIALS AND METHODS: A retrospective review was performed on 3,939 propensity score-matched patients aged 18 to 85 years who had SCI/surgery from 2000 to 2019. Patients were divided based on the development of postoperative complications, specifically cholecystitis with cholecystectomy. RESULTS: SCI consisted of quadriplegia (42%), paraplegia (53%), unspecified lesion of cervical spinal cord (3%), and thoracic spinal cord (2%). All groups were comparable regarding age, gender, body mass index, smoking status, and Charlson comorbidity Index. The incidence of acute cholecystitis with subsequent cholecystectomy among patients with SCI was 43.0 per 10,000 person-years (95% confidence interval: 41.51-44.49). Median follow-up was 36 months. The development of cholecystitis was comparable among females (54.5%) and males (45.5%), and among African Americans (52.5%) and Caucasians (47.5%). CONCLUSION: There is an association between SCI and development of acute cholecystitis among U.S. PATIENTS: As SCI patients do not present with the classic signs of biliary colic, risk assessment for the development of acute cholecystitis will guide patient management and allow neurosurgeons to weigh the risks and benefits of prophylactic treatment for gallbladder complications.

Investigational Therapies for Gunshot Wounds to the Spine: A Narrative Review.

STUDY DESIGN: This was a narrative review. OBJECTIVE: The objective of this study was to review the standards of care and triage protocol for gunshot wounds to the spine, highlighting innovative future treatment options that may be implemented in patients with spinal cord injury (SCI). SUMMARY OF BACKGROUND DATA: With the increased availability of firearms among the United States population, gunshot wounds to the spine are becoming a clinically relevant and devastating issue. Such injuries result in severe and diverse complications. SCIs due to gunshot wounds are the leading cause of morbidity and mortality, as they often result in complete or incomplete paraplegia. Current standards of care focus on preventing further damage rather than total cure or treatment of SCI. METHODS: A literature review was performed on the standards of care, triage protocol, associated conditions, current therapeutic options, and innovative treatment options for patients with gunshot wounds to the spine. RESULTS: The general standards of care for spinal gunshot wounds involve maintaining or renewal of mechanical spinal steadiness and neurological activity while limiting complications of treatment. Current treatment options include management of mean arterial pressure goals, drug therapies consisting of antibiotics, and surgical approaches. With recent innovations in molecular biology and cell transplantation, potentially new and promising treatment options for patients with SCI exist. These options include cell transplantation therapies, platelet-rich plasma administration, exosomal treatments, and mitochondrial-targeted therapeutics. Stem cell transplantation is promising, as several clinical studies have been completed. However, loss-to-follow-up, lack of long-term evaluation, and questionable randomization has limited the use of stem cells in the standard of care practice. Although not studied on human models to a gunshot wound, exosomal and mitochondrial-based treatment options have been studied both in vitro and in animal models with SCI. CONCLUSION: Newly emerging molecular and cellular therapy modalities for SCI contribute to the recovery process and may be utilized in conjunction with the current modalities for better outcomes.

Racial Differences in Iliac Crest Cancellous Bone Composition: Implications for Preoperative Planning in Spinal Fusion Procedures.

STUDY DESIGN: This was a retrospective cohort study. OBJECTIVE: The objective of this study was to determine whether race, specifically American white and American black, correlates with the ratio of cancellous to total bone at the iliac crest. SUMMARY OF BACKGROUND DATA: Studies have demonstrated higher proximal femur bone density in American blacks than American whites. However, whether differences occur at the iliac crest, a common site for autologous graft material in spinal fusion surgery, is not well studied. Understanding such differences could aid orthopedic surgeon decision-making regarding graft options. MATERIALS AND METHODS: A retrospective review was performed on 133 sequential patients ages 18-75 who underwent computed tomography scan of the pelvis, at a single academic medical center from January 1, 2014, to January 1, 2016. The cohort included 46 American white (21 females, 25 males) and 87 American black participants (40 females, 37 males), an average age of 51.8 years. Groups were matched regarding age, sex, body mass index, and Charlson Comorbidity Score. Measurements of cortical and cancellous bone thickness in the right and left iliac crests were performed using bone window protocol on computed tomography scans. Statistical significance was determined using a 2-tailed t test. RESULTS: The interobserver interclass correlation coefficient reliability (N=2) for measurements at the right iliac crest is 0.895 (95% confidence interval, 0.852-0.925), and the interclass correlation coefficient for the left iliac crest is 0.912 (95% confidence interval, 0.877-0.938). A statistically significant difference in the mean cancellous bone ratio was found between American black (0.667±0.065) and American white (0.750±0.051) groups (P<0.001). CONCLUSIONS: At the iliac crest, American black patients had a lower mean ratio of cancellous to the total bone as compared with American white patients. This population may benefit from alternative graft options. While iliac crest autograft remains the first option for fusion surgeries, alternative options should be considered to ensure that each patient receives the best-personalized care.

Sacroiliac joint dysfunction: pathophysiology, diagnosis, and treatment.

PURPOSE: To review the anatomy and function of the sacroiliac joint (SIJ), as well as the pathophysiology, clinical presentation, diagnostic criteria, and treatment options for SIJ dysfunction. METHODS: The SIJ serves an extremely crucial function in mobility, stability, and resistance against shear forces. Joint mobility becomes increasingly limited with age-related cartilaginous changes that begin in puberty and continue throughout life. Pain can also be localized to the SIJ itself, known as SIJ dysfunction. A literature review was performed on the anatomy, etiology, risk factors, diagnostic modalities, and treatment options for SIJ dysfunction. RESULTS: SIJ dysfunction is an under-recognized source of low back pain. Dysfunction can result from various clinical conditions, as well as abnormal motion or malalignment of the joint. Diagnosis and evaluation of SIJ dysfunction are difficult, with use of physical maneuvers and image-guided anesthetic injection. Non-operative treatment options are considered first-line due to high surgical complication rates. Such options include conservative management, radiofrequency treatment, nerve blocks, and articular injections. Surgical management involves open and percutaneous approaches. CONCLUSION: With the aging nature of the population, SIJ dysfunction has emerged as an extremely prevalent issue. Current research into the pathophysiology and risk factors of SIJ dysfunction is extremely important for planning preventative and therapeutic strategies. Various treatment options exist including conservative management, radiofrequency, nerve blocks, intra-articular or peri-articular injections, and surgical fixation. Improved diagnostic methods in clinical practice are thus critical to properly identify patients suffering from SIJ dysfunction, plan early intervention, and hasten return to function. LEVEL OF EVIDENCE I: Diagnostic: individual cross-sectional studies with the consistently applied reference standard and blinding.

Pelvic obliquity associated with neuromuscular scoliosis in cerebral palsy: cause and treatment.

STUDY DESIGN: Literature Review. OBJECTIVE: Review the etiology, clinical manifestations, diagnosis, and treatment of pelvic obliquity in cerebral palsy patients with neuromuscular scoliosis. Neuromuscular scoliosis (NMS) in cerebral palsy (CP) patients is rapidly progressive and often leads to an imbalance in musculoskeletal mechanics that extends to the pelvis. A horizontal misalignment of the pelvis in the frontal plane known as pelvic obliquity (PO) is a common finding in this population. When untreated, PO can exacerbate the back pain, postural strain, and walking difficulties experienced by these patients. Establishing the manifestation and treatment plan for PO in the setting of NMS can provide valuable insight for diagnosis and management. METHODS: A comprehensive literature review was performed on the etiology, clinical manifestations, diagnosis, and treatment of pelvic obliquity in the setting of NMS in CP. The advantages and limitations of measurement and treatment options were evaluated. RESULTS: PO is categorized into suprapelvic, infrapelvic, and intrapelvic causes, each presenting with a unique pattern of pathology. NMS in CP with hip contractures and structural deformities fall into these categories. The Maloney and O'Brien methods of pelvic measurement have demonstrated superior utility and are recommended for clinical diagnosis. The management of PO in NMS patients is focused on the cause of malalignment, with posterior fusion, contracture release, and osteotomy encompassing the mainstay of treatment. CONCLUSION: PO is commonly found in patients with NMS in cerebral palsy. There is currently no standard method for determining the PO angle. Interventions designed to reduce scoliotic curves and release tissue contractures can level the pelvis and restore proper alignment of the spine and sacrum in the coronal plane in these patients. Further understanding of the causes of PO in NMS, as well as the establishment of a standardized measuring technique and diagnostic parameters will allow for more effective treatment options and improve outcomes in patients with CP. LEVEL OF EVIDENCE: N/A.
