SAEM Clinical Images Series: Red Rash on My Legs

milaria

A 23-year-old female with no known past medical history presented with a rash concentrated on her legs, with a few areas on her arms and chest. The rash began the day before presentation when she became overheated while wearing sweatpants in 104°F weather. The rash was mildly pruritic but not painful. She denied any prior reaction to her sweatpants that she has had for several months. She denied any new soap or cosmetic use, prior rash, allergy, or medication use. Her review of systems and past medical history were negative.

rash

Vitals: Normal

Skin: An erythematous papular rash is concentrated and symmetric on her lower extremities. There are a few sparse lesions on her arms, thorax, and abdomen with sparing of the palms, soles, and face. No pustules or vesicles are noted. There is no scale or crust. No other skin lesions are present. The rest of the examination is normal.

Non-contributory

Miliaria, or prickly heat (heat rash).

Miliaria, also known as prickly heat or heat rash, is caused by blocked eccrine sweat glands and ducts. Exposure to heat with sweating causes eccrine sweat to pass into the dermis or epidermis causing a rash. It is common in warm and humid climates during the summer months. It can affect up to 30% of adults living in hot and humid conditions. It may present as vesicles, papules, or pustules depending on the depth of the eccrine gland obstruction. In adults the rash is most likely seen where clothes rub on the skin. Infants and children typically have lesions on the upper trunk, neck, and head. Miliaria is a clinical diagnosis. Treatment involves measures to reduce sweating and exposure to hot and humid conditions. Air conditioning and the reduced humidity of indoor environments are helpful. If significant inflammation is present with pruritis, some improvement can be seen with 0.1% triamcinolone topically, though ointment should be avoided and only cream or lotion applied.

Take-Home Points

  • Miliaria, or prickly heat, is caused by sweating and blocked eccrine sweat glands.
  • Treatment involves retreating to cool, indoor environments.
  • Triamcinolone 0.1% cream or lotion may reduce pruritis.

SAEM Clinical Images Series: Seeing Double

ophthalmoplegia

A 53-year-old woman with no significant past medical history presented to the emergency department with a 3-day history of double vision on leftward gaze. She initially presented to urgent care with a chief complaint of chest heaviness and concern that her blood pressure was too high, but was sent to the emergency department for further cardiac and neurological evaluation after her urgent care provider noticed abnormal eye movement. She endorsed mild, intermittent headaches associated with diplopia when looking to the left. However, she denied any blurry vision when looking forward. She denied any trauma or falls.

Vitals: Temp 36.7°C; Heart rate 86 beats/min; Respirations 18 breaths/min; BP 150/82 mmHg; O2 Saturation: 100%

General: No acute distress and appears comfortable. She is alert and oriented.

Eyes: Equal, round and reactive pupils and severely limited adduction of the right eye, all other extraocular movements are normal.

Neuro: All other cranial nerves are intact, normal tone in bilateral upper and lower extremities, normal sensation bilaterally to light touch and pinprick except for mildly decreased sensation to pinprick over right ulnar distribution.

CBC, CMP, EKG, and Troponins were normal.

Lipid panel: Cholesterol 241 (H)

CSF: No oligoclonal bands, Protein 197 (H), Albumin 57 (H), IgG 16.3 (H)

Internuclear ophthalmoplegia (INO) is defined as the inability to adduct the eye due to a lesion in the medial longitudinal fasciculus (MLF) and can be accompanied by nystagmus in the same eye. The two main causes of internuclear ophthalmoplegia are demyelination of the medial longitudinal fasciculus (MLF) from multiple sclerosis (MS) and ischemic cranial nerve damage from stroke. However, a comprehensive list of causes of INO includes: infarction (ischemic stroke), demyelination (MS), tumor, encephalitis, hemorrhage, hydrocephalus, Chiari malformation, infection (Lyme Disease), and trauma. Usually, MS is seen in younger patients where both eyes are affected whereas strokes occur more often in older patients and only one eye is affected.

The therapeutic approach focuses on treating the underlying cause and hence determining the etiology is of immense importance. A brain MRI should be ordered to evaluate for ischemia and demyelination. Proton density imaging is beneficial in identifying MLF lesions in multiple sclerosis. A lumbar puncture can also help rule out infections. A kappa-free light chain antibody test is a faster and less expensive way to test for multiple sclerosis than looking for oligoclonal bands in the CSF.

Given this patient’s relatively young age and vascular risk factors, stroke is highest on the differential. Her brain MRI showed areas of restricted diffusion in the right dorsal medial pons correlating with her exam. It also showed periventricular and subcortical white matter changes which is a non-specific finding in chronic small vessel ischemic changes vs underlying demyelinating disease. This was followed up with an MRI of her spine that demonstrated C5-6 stenosis with associated cord edema and an additional enhancing C3-4 lesion concerning for demyelinating disease. Her lumbar puncture revealed 3 nucleated cells and a protein of 197 but was deemed a traumatic tap. There were no oligoclonal bands. The initial brain MRI findings favored stroke for which she underwent a stroke work-up and was ultimately discharged on aspirin and atorvastatin for secondary prevention. However, due to concern for demyelinating disease, she was also treated with a 3-day course of IV methylprednisolone. Ultimately, she was discharged and asked to come back for a follow-up for repeat brain imaging and evaluation. A recent study showed that patients with unilateral or bilateral INO who experienced symptomatic diplopia were commonly managed by uniocular occlusion. Another case report showed that a young man who presented with acute INO responded rapidly to treatment with IV alteplase when administered within 2 hours of the onset of symptoms and resolution within 15 minutes. A case series revealed that 1 in 5 patients failed to recover from an INO. Hence, it is critical that a definitive workup is carried out to determine the etiology of the INO.

Take-Home Points

  • Brain MRI including DWI is a useful diagnostic tool for INO.
  • Unilateral INO is more frequently related to ischemic/vascular causes whereas bilateral INO is associated with MS.

SAEM Clinical Images Series: Purple Finger

bruising

A 30-year-old female with a past medical history of Crohn’s Disease presented to the ED for evaluation of an acutely bruised right 4th finger. She stated she was typing on a computer keyboard approximately 10 minutes prior to presentation and she noticed a sudden popping sensation at the base of her right ring finger. After the popping sensation, she noticed a cool sensation of the finger and numbness to the entire finger. Shortly after that, the finger turned purple, so she came to the Emergency Department for evaluation. She denied pain in the hand and has had no problems moving the finger. She denied trauma to the hand or finger. No other complaints or issues. She noted that she has had this once in the past, which self-resolved on its own in 10 days a few months ago in the same situation.

General: No acute distress

Right hand: Right 4th finger with diffuse ecchymosis across the palmar surface of the finger with swelling, no tenderness, ecchymosis does not extend to the palmar surface of the hand. FROM of all 5 digits at both the DIP and PIP joints. Sensation to the right 4th finger is decreased to light touch.

Left hand: Normal

Extremities: Normal other than the right ring finger

Pulses: Radial pulses 2+ bilaterally

Remainder of the physical exam is normal.

Non-contributory

Achenbach Syndrome, also known as paroxysmal finger hematomas, is a self-limited condition. It typically afflicts middle-aged women and presents as spontaneous subcutaneous bleeding of the palmar surface of the middle and index fingers of the hand. Patients usually present with pain, swelling, tingling, numbness, and ecchymosis. Many report a burning sensation to the finger. Diagnosis is based on presentation and exam. Laboratory testing and imaging do not show pathologic findings in this disorder. There is no known treatment and symptoms usually resolve on their own in a few days, but can last up to months. It has been shown to be recurrent, but without a known cause. Given the dramatic presentation of Achenbach Syndrome, it is important to be aware of this benign process to prevent unnecessary testing and workup, as it is a self-limited process.

Take-Home Points

  • Achenbach Syndrome is a benign, self-limited condition that does not require treatment
  • Relapses may occur.
  • No testing is indicated, but if sent will be normal including laboratory studies and arterial dopplers of the extremity.

SAEM Clinical Images Series: Workout Gone Wrong

hyphema

A 28-year-old male presented to the ED for evaluation of an injury to his right eye. While working out with an exercise band, it snapped back, hitting the patient in the right eye. He experienced blurry vision and excess eye tearing immediately after the incident occurred. The patient also developed gross blood over the front of the eye.

Vitals: Temp 98°F, HR 73, BP (135/77), RR 16, SpO2 99%

HEENT: Gross blood in the anterior portion of the right eye (grade I). The right pupil is dilated with minimal responsiveness to light. Visual Acuity: OD 20/70, OS 20/10, Both 20/10. Pressure: OD (21), OS (16). Decreased visual field on the right when compared to the left. Staining with tetracaine and fluorescein did not reveal any evidence of corneal abrasion or ulceration. Left eye is atraumatic in appearance.

Neurologic: Alert and oriented x3

Non-contributory

A Hyphema is a collection of blood in the anterior chamber of the eye due to the tearing of the iris root vessels.

The most common cause is blunt trauma to the eye. Spontaneous hyphemas can also occur and are often associated with sickle cell disease. It can be caused by ocular surgery and neoplastic disease, as well.

Take-Home Points

  • Hyphemas are an ocular emergency and should prompt immediate consultation with an ophthalmologist.
  • Patients should elevate the head of the bed to 45 degrees since layering of the blood is gravity-dependent.
  • Treatment usually involves the administration of steroidal and cycloplegic ophthalmic drops.

SAEM Clinical Images Series: Not Your Usual Irritated Eye

eye irritation

In July 2022, a 32-year-old male with a past medical history of HIV (on antiretroviral therapy, CD4 390, viral load undetectable) presented to the emergency department with constitutional symptoms and a rash for 4-5 days. His symptoms included malaise, body aches, subjective fevers, a sore throat, tender, swollen neck glands, body rash, and irritation of his left eye. He also noticed fluid-filled vesicles on his face, neck, trunk, and extremities. He denied travel outside the U.S. but reported a recent trip to New Orleans. He denied any new sexual partners or known exposure to individuals with similar symptoms.

monkeypox

Vitals: BP 135/83; Pulse 104; Temp 100.2 °F (37.9 °C); Resp 22; SpO2 99%

Constitutional: Alert, no acute distress

HEENT: 1×1 mm raised lesion to the left medial canthus/caruncle. No appreciated LAD. Oropharynx is clear and moist, and mucous membranes are normal.

Cardiovascular: Tachycardia, regular rhythm, and normal heart sounds.

Pulmonary: Breath sounds normal, unlabored respirations.

Abdominal: Soft. Non-tender.

Skin: Numerous 5-6 mm erythematous macules, bland fluid-filled vesicles, and umbilicated lesions throughout the face, neck, trunk, and extremities.

Complete Blood Count (CBC): WBC: 19.5 10^3/mcL, Hemoglobin: 15.2 gm/dL, Hematocrit: 43.6%, Platelet count: 325 10^3/mcL

Comprehensive Metabolic Panel (CMP): Within normal limits

RPR titer: Reactive, 1:4

Syphilis antibody IgG and IgM: Positive

Orthopoxvirus DNA: Pending

HIV RNA: Pending

The patient has Monkeypox with involvement of the caruncle of the left eye. The patient tested positive for non-variola orthopoxvirus DNA. Ophthalmology was consulted and did not find any other signs of compromise to the eye and recommended treatment with artificial tears. The patient received 14 days of Tpoxx. The patient’s eye lesion and symptoms resolved and he was discharged on hospital day eight.

Ocular lesions are a rare presentation of the monkeypox virus. There is limited literature documenting eye involvement and pictographic examples of its presentation. During the current outbreak, ocular involvement has been used as a criteria for hospital admission. The most commonly seen ophthalmologic lesions include a vesicular rash of the orbital and periorbital skin (25%), focal conjunctiva lesions, blepharitis, and conjunctivitis. Rarely, lesions can process to corneal ulcerations, keratitis, and vision loss. Given the late risk of vision loss in cases of ocular manifestations, clinicians should be aware of the varied presentation of ocular lesions associated with the monkeypox virus.

Take-Home Points

  • While rare, ocular involvement of Monkeypox is associated with vision loss, and should be promptly identified and addressed by a clinician.
  • If there is ocular involvement of primarily cutaneous pathology, a thorough eye exam is indicated in the initial assessment of the patient.

SAEM Clinical Images Series: Two Pupils for the Price of One

pupil

A 24-year-old female with no pertinent PMHx presents to the ED with a chief complaint of eye pain. She reported a 10-day history of worsening right eye pain following being punched in that eye. She had been managing her pain with ice and had not taken any OTC medications. Her mom convinced her to go to the ED and she first went to an outside hospital, but was referred to come to our institution. She endorsed photophobia and blurry vision but denied double vision. She further noted occasional left-sided headaches.

 

Vitals: Within normal limits

General: The patient is alert and conversant. No apparent distress.

HEENT: NC, AT. Mucous membranes moist. Neck supple. Minimal pain with EOM. No double vision in right eye. Right eye discoloration at superior portion. Divided abnormal pupil. Mild superior periorbital swelling. Visual acuity: Right – 20/400, Left – 20/25

CV: Regular rate and rhythm.

Resp: Clear to auscultation bilaterally.

Abd: Soft, non-tender, non-distended.

Neuro: Alert. Motor and sensation grossly intact.

MSK: Moves all extremities, no joint pain or tenderness.

Skin: No obvious rashes or skin lesions.

Non-contributory

This is traumatic iridodialysis. It is typically related to significant blunt trauma to the eye that pulls the iris away from the ciliary body at the scleral spur [1]. That is what causes the split appearance or “two pupil” phenomenon.

Take-Home Points

  • Whenever you have a two-pupil phenomenon consistent with traumatic iridodialysis, the differential should always include penetrating injury to the globe, globe rupture, scleral rupture, hyphema, and lens dislocation. These additional findings may warrant urgent surgical repair or close monitoring of IOP. [2]
  • Consider bedside ultrasound to rule out posterior pathology (retinal detachment, vitreous hemorrhage, etc.).
  • Always refer to Ophthalmology, more urgently if the trauma was recent vs multiple days out (as in this case).

SAEM Clinical Images Series: Neonatal Rash

An 18-day-old male presented for a rash on his face for two days. The patient was born via spontaneous vaginal delivery full term without complications to a mom who has a history of genital HSV but without active lesions at delivery and on acyclovir. The patient presented with a vesicular rash on his face including around his eyes. He had conjunctival discharge noted by mom. Otherwise, he was well-appearing, acting normally, and eating/voiding/stooling normally.

 

neonatal rash

General: Well appearing, acting appropriately for age

HEENT: Scalp normal. Anterior fontanelle soft and flat. Vesicular appearing rash with erythematous base in clusters noted around eyes, cheek, and chin. Fluorescein staining with corneal abrasion noted at 4 o’clock region on right eye, no dendritic pattern. Scant yellow discharge noted from left eye. TM normal bilaterally. Oropharynx clear.

Neuro: Normal tone, moving all extremities

Skin: Flaky skin, no rash noted elsewhere except as listed above (Photos taken after fluorescein)

CBC: Normal

LFTs: Normal

BMP: Unremarkable

CRP: Negative

Lab results for HSV were negative:

HSV 1 and 2 (chin): negative

HSV 1 and 2 (near eye): negative

HSV 1 and 2 (nose, mouth, rectum): negative

HSV 1 blood Igg: negative

HSV 2 blood Igg: positive (reflective of maternal antibody status)

What was once called “neonatal acne” now known as neonatal cephalic pustulosis is usually seen in the first three weeks of life. Usually, it appears as pustulo-papules on the face, around the eyes, on the cheeks, and chin. Some studies have suggested that neonatal cephalic pustulosis is caused by Malassezia species. As the rash is self-limiting, treatment is not necessary.

Take-Home Points

  • When a vesicular rash is in a neonate < 1 month and all over the face, consider benign neonatal pustular lesions such as neonatal cephalic pustulosis.
