Oncologic Emergencies: Palliative Care in the Emergency Department Setting.

BACKGROUND: Palliative care is an essential component of emergency medicine, as many patients with terminal illness will present to the emergency department (ED) for symptomatic management at the end of life (EOL). OBJECTIVE: This narrative review evaluates palliative care in the ED, with a focus on the literature behind management of EOL symptoms, especially dyspnea and cancer-related pain. DISCUSSION: As the population ages, increasing numbers of patients present to the ED with severe EOL symptoms. An understanding of the role of palliative care in the ED is crucial to effectively communicating with these patients to determine their goals and provide medical care in line with their wishes. Beneficence, nonmaleficence, and patient autonomy are essential components of palliative care. Patients without medical decision-making capacity may have an advance directive, do not resuscitate or do not intubate order, or Portable Medical Orders for Life-Sustaining Treatment available to assist clinicians. Effective and empathetic communication with patients and families is vital to EOL care discussions. Two of the most common and distressing symptoms at the EOL are dyspnea and pain. The most effective treatment of EOL dyspnea is opioids, with literature showing little efficacy for other therapies. The most effective treatment for cancer-related pain is opioids, with expeditious pain control achievable with a rapid fentanyl titration. It is also important to address nausea, vomiting, and secretions, as these are common at the EOL. CONCLUSIONS: Emergency clinicians play a vital role in EOL patient care. Clear, empathetic communication and treatment of EOL symptoms are essential.

A 61-year-old Female with Right Upper Abdominal Pain.

CASE PRESENTATION: A 61-year-old female presented to the emergency department with right upper quadrant abdominal pain following a cholecystectomy 18 days prior. Computed tomography (CT) of her abdomen demonstrated a large abscess in her post-hepatic fossa. She was admitted to the general surgery service and received an image-guided percutaneous drain placement with interventional radiology with immediate return of purulent material. She was discharged home after a three-day hospital course with outpatient antibiotics and follow-up. DISCUSSION: Patients may have multiple complications following cholecystectomy, including infection, bleeding, biliary injury, bowel injury, or dropped stone. The emergency clinician must consider cholecystectomy complications including gallbladder fossa abscess in patients presenting with abdominal pain in the days to weeks following cholecystectomy, especially if they present with signs of sepsis. Critical actions include obtaining CT and/or ultrasonography, initiating broad spectrum antibiotics, and obtaining definitive source control by either surgery or interventional radiology.

An emergency medicine-focused review of malignant otitis externa.

INTRODUCTION: Malignant otitis externa (MOE) is a progressive infection of the external auditory canal (EAC). This disease is rare but has severe morbidity and mortality. OBJECTIVE: This narrative review provides an overview of malignant otitis externa for emergency clinicians. DISCUSSION: MOE is an invasive external ear infection that spreads to the temporal bone and can further progress to affect intracranial structures. Complications of advanced MOE include cranial nerve involvement, most commonly the facial nerve, and intracranial infections such as abscess and meningitis. The most common causative agent of MOE is Pseudomonas aeruginosa, but others include methicillin-resistant Staphylococcus aureus and fungi. Major risk factors for MOE include diabetes mellitus, immunosuppression, and advanced age. Red flags for MOE include severe otalgia (pain out of proportion to exam) or severe otorrhea, neurologic deficits (especially facial nerve involvement), previously diagnosed otitis externa not responsive to therapy, and patients with major risk factors for MOE. Examination may show purulent otorrhea or granulation tissue in the EAC, and culture of EAC drainage should be performed. Diagnosis is aided by computed tomography (CT) with intravenous contrast, which may demonstrate bony destruction of the temporal bone or skull base. When suspecting MOE, early consultation with an otolaryngologist is recommended and antibiotics with pseudomonal coverage are needed. Most patients with MOE will require admission to the hospital. CONCLUSIONS: MOE is a rare, yet deadly diagnosis that must be suspected when patients with immunocompromise, diabetes, or advanced age present with severe otalgia. Rapid diagnosis and treatment may prevent complications and improve outcomes.

55 year-old Female with Hematuria.

CASE PRESENTATION: A 55 year-old female presented to the emergency department with left sided abdominal pain and hematuria. Computed tomography scan of her abdomen and pelvis demonstrated a large left renal mass with extension into the left ureter, left renal vein, and inferior vena cava. She was admitted and treated for presumed renal cell carcinoma (RCC). DISCUSSION: RCC may present with abdominal or flank pain and hematuria, but more commonly presents with vague symptoms. RCC should be suspected in a patient presenting with hematuria and abdominal or flank pain, especially if vague symptoms such as fatigue or anorexia are also present.

Prognosis of diffuse axonal injury with traumatic brain injury.

BACKGROUND: Determine the prognostic impact of magnetic resonance imaging (MRI)-defined diffuse axonal injury (DAI) after traumatic brain injury (TBI) on functional outcomes, quality of life, and 3-year mortality. METHODS: This retrospective single center cohort included adult trauma patients (age > 17 years) admitted from 2006 to 2012 with TBI. Inclusion criteria were positive head computed tomography with brain MRI within 2 weeks of admission. Exclusion criteria included penetrating TBI or prior neurologic condition. Separate ordinal logistic models assessed DAI's prognostic value for the following scores: (1) hospital-discharge Functional Independence Measure, (2) long-term Glasgow Outcome Scale-Extended, and (3) long-term Quality of Life after Brain Injury-Overall Scale. Cox proportional hazards modeling assessed DAI's prognostic value for 3-year survival. Covariates included age, sex, race, insurance status, Injury Severity Score, admission Glasgow Coma Scale Score, Marshall Head computed tomography Class, clinical DAI on MRI (Y/N), research-level anatomic DAI Grades I-III (I, cortical; II, corpus callosum; III, brainstem), ventilator days, time to follow commands, and time to long-term follow-up (for logistic models). RESULTS: Eligibility criteria was met by 311 patients, who had a median age of 40 years (interquartile range [IQR], 23-57 years), Injury Severity Score of 29 (IQR, 22-38), intensive care unit stay of 6 days (IQR, 2-11 days), and follow-up of 5 years (IQR, 3-6 years). Clinical DAI was present on 47% of MRIs. Among 300 readable MRIs, 56% of MRIs had anatomic DAI (25% Grade I, 18% Grade II, 13% Grade III). On regression, only clinical (not anatomic) DAI was predictive of a lower Functional Independence Measure score (odds ratio, 2.5; 95% confidence interval, 1.28-4.76], p = 0.007). Neither clinical nor anatomic DAI were related to survival, Glasgow Outcome Scale-Extended, or Quality of Life after Brain Injury-Overall Scale scores. CONCLUSION: In this longitudinal cohort, clinical evidence of DAI on MRI may only be useful for predicting short-term in-hospital functional outcome. Given no association of DAI and long-term TBI outcomes, providers should be cautious in attributing DAI to future neurologic function, quality of life, and/or survival. LEVEL OF EVIDENCE: Epidemiological, level III; Therapeutic, level IV.
