Posterior reversible encephalopathy syndrome (PRES) is an unusual condition typified by acute
visual impairment caused by sudden, marked parieto-occipital vasogenic edema. Thought to be
inflammatory in origin, it has been described in patients undergoing chemotherapy, with autoimmune
disease, and in some infections. We report a case of PRES that occurred one week after an episode
of acute pancreatitis in an otherwise healthy 40-year-old female. There was progressive visual
impairment over a 24-hour period with almost complete visual loss, with characteristic findings on
magnetic resonance imaging. After treatment with steroids, the visual loss recovered. Clinicians
should retain an index of suspicion of this rare condition in patients with visual impairment after acute
pancreatitis.

A 14-year-old African American male presented to the emergency department with worsening left
eye redness, swelling, and vision loss over the preceding three days. History was notable for similar
eye redness and swelling without vision loss four months earlier, which improved following a brief
course of prednisone. He endorsed mild eye irritation and tearing with bright lights. There was
no history of fever, respiratory symptoms or trauma. Mother was medicating patient with leftover
antibiotic eye drops x3 days without improvement. Physical examination on presentation notable
for proptosis of left eye, lid, and periorbital swelling, mild scleral injection, and central vision loss in
affected eye (20/200 OS, 20/25 OD). Extraocular movements and pupillary exam were normal. No
corneal fluorescein uptake, abnormal cell, flare, or siedel sign were seen during slit lamp exam. Eye
pressures were 24 mmHg in both eyes. Bedside ultrasonography was performed (Figure 1 showing
retinal detachment, Ultrasound Video 2 showing detachment in orbital scan).

A 37-year-old male presented to the emergency
department (ED) in police custody for “medical clearance”
before being taken to jail. The patient was approached by
police officers for suspicion of selling illicit drugs. When
approached by police he ran away and was witnessed to
swallow several small plastic baggies suspected to contain
heroin. He was apprehended and brought to the ED.
On arrival, he was asymptomatic with a blood pressure
144/83mmHg, heart rate 67bpm, respiratory rate of 19bpm,
oxygen saturation of 99% on room air and afebrile. A Glasgow
coma score was 15 and he was alert and oriented to person,
place and time. Patient had a negative review of systems.
On physical examination pupils were 4mm and reactive to
light, lungs clear to auscultation and had normal respiratory
rate with normal cardiovascular exam. Abdomen was soft,
non-tender and non-distended with present bowel sounds.
The patient admitted to ingesting approximately 20 packets
of heroin to avoid being charged with possession. The patient
declined activated charcoal and whole bowel irrigation (WBI)
with polyethylene glycol-electrolyte solution (PEG-ELS). The
patient declined a urine toxicology immunoassay screen. A
computed tomography (CT) of his abdomen with contrast was
obtained and read as normal except for a cluster of foreign
bodies within the distal stomach likely contained within a
plastic bag.

A previously healthy 27-year-old man presented to the
emergency department with a three-day history of left lower
quadrant pain. He denied fever, nausea, vomiting, or diarrhea.
Vital signs were unremarkable, and physical examination
revealed tenderness in the left iliac fossa without peritoneal
signs. His leukocyte count and C-reactive protein were slightly
elevated. On abdominal computed tomography (CT) (Figure),
a fatty ovoid mass abutting sigmoid colon demonstrated the
infarcted or inflamed appendix epiploica. A surrounding
hyperdense rim (hyperattenuating ring sign) represented the
inflamed visceral peritoneal covering, and the central linear
hyperdensity corresponded to the thrombosed central vessel.

Introduction: Currently, it is common practice in the emergency department (ED) for pain relief
in hip-fracture patients to administer pain medication, commonly systemic opioids. However, with
these pain medications come a high risk of side effects, especially in elderly patients. This study
investigated the safety profile and success rate of fascia iliaca compartment block (FICB) in a
busy ED. This ED was staffed with emergency physicians (EPs) and residents of varying levels of
experience. This study followed patients’ pain levels at various hourly intervals up to eight hours
post procedure.
Methods: Between September 2012 and July 2013, we performed a prospective pilot study on
hip-fracture patients who were admitted to the ED of a teaching hospital in the Netherlands. These
patients were followed and evaluated post FICB for pain relief. Secondary outcome was the use of
opioids as rescue medication.
Results: Of the 43 patients in this study, patients overall experienced less pain after the FICB
(p=0.04). This reduction in pain was studied in conjunction with the use and non-use of opioids. A
clinically meaningful decrease in pain was achieved after 30 minutes in 62% of patients (54% with
the use of opioids, 8% without opioids); after 240 minutes in 82% of patients (18% with opioids, 64%
without opioids); after 480 minutes in 88% of patients (16% with opioids, 72% without opioids). No
adverse events were reported.
Conclusion: In a busy Dutch ED with rotating residents of varying levels of experience, FICB seems
to be an efficient, safe and practical method for pain reduction in patients with a hip fracture. Even
without the use of opioids, pain reduction was achieved in 64% of patients after four hours and in
72% of patients after eight hours.

A 35-year-old male presented with lower gum
pain associated with fever, chills, and sore throat. His
medical history included intravenous drug use, human
immunodeficiency virus infection, and hepatitis C. Physical
exam revealed tachycardia, a temperature of 38.9°C, anterior
cervical lymphadenopathy, halitosis, an edematous lower lip,
and purulent ulcers anterior and posterior to lower central
incisors with marked tenderness and erythema (Figure).
His laboratory work was notable for a low white blood cell
count (2.6 thousand/µl), neutropenia (0.11 thousand/µl), a
low absolute CD4 lymphocyte count (0.5 thousand/µl), and
elevated C-reactive protein (129mg/L) and sedimentation
rate (23mm/hr). A computed tomography study showed a
0.5×1.3×0.3cm abscess anterior to the mandibular symphysis.

A 41-year-old female presented to the emergency
department with nausea, vomiting and foreign body sensation
in her throat. The patient had multiple co-morbidities including
hypertension, diabetes, cervical cancer and gastroparesis with
gastrojejunostomy (GJ) tube. The patient had stable vitals, was
in no respiratory distress, and her only complaint was mild throat
pain and abdominal pain at the GJ tube insertion site. Physical
exam revealed a foreign object in the oropharynx (Figure 1).
Abdominal exam showed a soft, non-distended, non-tender
abdomen with GJ-tube and colostomy in place. Abdominal series
and upright chest radiograph were obtained (Figure 2).

Often discovered only after an extensive work up for hemoptysis and hematemesis, vallecular varices
are a rare cause of oral bleeding that increase patient morbidity due to delay of diagnosis.
We describe an 89-year-old male who presented with a week of intermittent oral blood production. A
vallecular varix was identified on fiberoptic laryngoscopy after studies for hematemesis and hemoptysis
had been performed, including negative esophagogastroduodenoscopy and bronchoscopy.
Awareness of this pathology and key points in the patient history can direct the clinician toward the
correct diagnosis, expediting treatment and limiting invasive diagnostic procedures for pulmonary or
gastric etiologies of bleeding.

A 42-year-old male was assisted from a car in front
of our inner city stand-alone emergency department (ED)
with a stab wound to the right chest. He was confused and
bleeding; his past medical history was unknown. The patient
was diaphoretic, pale and confused with a large vertical stab
wound over his right chest with no other obvious injuries.
On initial exam in the outlying ED, his back was obscured
by blood. He was transferred to the trauma center where
during a full secondary survey a 2cm wound was located over
the patient’s lumbar spine. The patient was stabilized and
taken for imaging. No focused assessment with sonography
for trauma (FAST) was done at either site; however, the
FAST exam, which emphasizes the search for extraluminal
blood, would not have been expected to find a foreign body

A 68-year-old male with a history of prostate cancer
presented with a two-day history of fever and left flank pain.
Vital signs included a temperature of 39.4 degrees Celsius with
93% oxygen saturation and heart rate of 112 beats per minute. An
upright chest radiograph showed concern for free intraperitoneal
air (Figure) with a white blood cell count of 17.3. A computed
tomography of the abdomen and pelvis revealed a Chilaiditi sign
with pyelonephritis, which was confirmed on urinalysis. He was
admitted for intravenous antibiotics.

An 81-year-old woman was admitted to our emergency
department (ED) with neck swelling (Figure 1A) and
advancing dyspnea. Stridor was noted on auscultation of
her neck, and her breathing was labored. We immediately
diagnosed airway obstruction, and emergency intubation was
performed using a video laryngoscope (AWS-S100L®, Pentax
Corporation, Tokyo, Japan). The epiglottis was found to have
shifted to the left on chest video images and chest radiograph.
