SAEM Clinical Images Series: I’m Plugged Up

foreign body

A 56-year-old male with a history of crack cocaine and opiate drug use presented to the Emergency Department (ED) with concerns about a persistent dry cough for seven days. The cough started after smoking cocaine from a homemade glass pipe. The day before arrival, he developed sharp chest pain with coughing associated with shortness of breath and a sore throat. The patient denied fevers, chills, or shortness of breath. He denied hemoptysis, nausea, vomiting, and diarrhea. A chest x-ray was obtained with the findings seen below.

Case Question: Why did the radiopaque foreign body in images 1 and 2 localize to that lung region?

Images 1 and 2 show a radiopaque object in the right bronchus intermedius. By age 15 the aorta makes a prominent indent on the trachea and left mainstem bronchus, increasing the acute angle of the left bronchus compared to the trachea. This results in a relative straightening of the right mainstem bronchus in relation to the trachea and left mainstem bronchus. Thus, foreign bodies are more commonly found in the right bronchial tree of adults and children over 15 years old. In children younger than 15 years of age the angle of the left and right bronchus are symmetrical thus bronchial aspirated foreign bodies are equally likely to be found in either lung. In younger children the relative anatomical narrowing of the tracheobronchial tree results in more proximal airway obstructions at the level of the glottis, larynx, or trachea. (1)

Case Question: What is the preferred treatment to prevent complications from foreign body aspiration in the tracheobronchial tree?

Picture 3 shows a steel wool plug after it was removed from the right bronchus by flexible bronchoscopy. The patient had used the steel wool as a filter for smoking cocaine and accidentally inhaled it during use. Steel wool, like most foreign bodies, causes direct trauma to the tracheobronchial tree as well as post-obstructive pneumonia. Steel wool filters present an added hazard in crack cocaine smoking due to thermal injury to the upper airway (2). Flexible bronchoscopy is the preferred modality for evaluation and treatment of tracheobronchial tree foreign bodies in adults. It has several advantages over rigid bronchoscopy. Flexible bronchoscopy allows better visualization of the distal airways and may be performed using local anesthesia under procedural sedation. (3) In one meta-analysis the procedure had a 90% success rate for foreign body removal. (4) The use of flexible bronchoscopy in children is less clear. A comparison of rigid verses flexible bronchoscopy in children showed a lower rate of respiratory complication in the rigid bronchoscopy group. However, there was no statistically significant overall complication rate for the two modalities. (5)

Case Discussion

Take-Home Points

Right bronchial foreign bodies are more common after age 15.
Steel wool used as a filter in a glass pipe may lead to thermal or mechanical injuries to the upper airway, and post obstructive pneumonia due to aspiration of the entire steel wool plug.
Flexible bronchoscopy is the procedure of choice for the removal of bronchial foreign bodies in adults.

Pigtail catheter for pleural drainage: Tips to minimize complications

Traditionally large-bore tube thoracostomy has been the standard of care for treating many acute intrathoracic pathologies [1]. However, the advent of less invasive small-bore chest tubes, also known as pigtail catheters, has gradually led to a paradigm shift. Pigtails provide a less invasive and often better tolerated alternative to traditional chest tubes and allow for adequate treatment of pneumothoraces and uncomplicated pleural effusions [1-5]. Unfortunately, these less invasive catheters are not without complications – both unique and similar to traditional chest tubes.

Case

A 48 year-old male with a history of hypertension and polysubstance abuse presented to the emergency department (ED) for shortness of breath and was found to have a left sided parapneumonic pleural effusion (Figure 1). The patient underwent thoracentesis and placement of a pigtail catheter using the Seldinger technique to drain the fluid collection. Pigtail catheter placement was confirmed by chest x-ray (Figure 2).

Figure 1: Chest x-ray with left sided pleural effusion

Figure 2: Chest x-ray with the pigtail catheter in the left chest

Case Progression

Despite pigtail catheter placement, there was minimal drainage from the catheter. In collaboration with the inpatient team, intrapleural thrombolytics were administered via the pigtail catheter did not resolve the issue. Although the patient’s chest x-ray did improve after the procedure, the patient continued to deteriorate clinically and became increasingly hypoxic.

A CT angiogram was then performed and showed that the pigtail catheter had been accidentally introduced through the lung parenchyma and was lodged in the left main stem bronchus (Figure 3). This was confirmed on bronchoscopy (Figure 4).

Figure 3: Chest CT angiogram showing the pigtail catheter (arrow) in the left mainstem bronchus

Figure 4: Bronchoscopy view of the left mainstem bronchus showing the pigtail catheter

This case highlights one of the more rare and potentially severe complications of small-bore chest tubes. With the increasing utilization of such devices, this case highlights the need for better education about the indications, complications, and troubleshooting approaches with these pigtail catheters.

Complications

The overall complication rate for small-bore catheters is lower than their large-bore counterparts, partly because of their smaller caliber. Also unlike traditional large-bore tube thoracostomy, the lack of tactile feedback (not feeling the pleural puncture ‘pop’ with Kelly clamps and then identifying the intrapleural space with the finger) can lead to malpositioning complications. Both approaches, however, share common complications:

Most common complication: Chest tube kinking and obstruction [6, 7, 10]
- Due to the small caliber of the pigtail catheter, it can easily become twisted or kinked between the pleura and lung parenchyma, obstructed within lung fissures, or kinked externally between the body and environment [9].
- Obstruction may also occur from clotted blood [9] or pleural effusion loculations [12, 13] within the catheter lumen.
  - For loculated effusions and empyemas, an interdisciplinary inpatient discussion should weigh the pros and cons of intrapleural thrombolytics versus surgical drainage and pleurodesis.
  - One often used thrombolytic regimen is the MIST-II protocol, which involves the combination of alteplase (tPA) 10 mg BID plus dornase alfa (DNase) 5 mg BID [13, 14].
Laceration of tissue/vessel [2, 3, 6, 8]
- Can be prevented by using standard landmarks and inserting above the rib margin
Air emboli [2, 3, 6, 9]
- Thought to be due to parenchymal injury resulting in a fistula involving the pulmonary vessels
Parenchymal injury [9]

Tips to Minimize Pigtail Complications

Utilize ultrasonography to map out the deepest pocket of fluid and to measure the distance from the chest wall to the heart [9].
- For patients with a large body habitus, there may be too much tissue for your needle to reach the pleural cavity [9]. Use a traditional larger-bore chest tube instead.
Insert the catheter above the target rib to avoid the neurovascular bundle and reduce the risk of bleeding [9].
Place the catheter anterior to the anterior superior iliac spine to reduce the risk of the patient lying on and kinking the tube [9].
If the catheter appears correctly positioned on AP chest x-ray but is malfunctioning, consider obtaining additional imaging to confirm placement [11]:
- Lateral view chest-xray, or
- Chest CT (can also help characterize the pleural effusion)

SAEM Clinical Images Series: A Lethal Combination of Skin and Lung Findings

dermatomyositis

A 49-year-old female with a past medical history of recurrent diverticulitis initially presented with one month of shortness of breath and a minor nonproductive cough for which she was started on doxycycline by her primary care provider. She then developed a rash on her chest, upper back, and face. Antibiotics were switched to amoxicillin and azithromycin. She underwent a brief admission of six days for shortness of breath but did not have an oxygen requirement at that time. She was evaluated by pulmonology (evaluated for cocci, unknown results), and then discharged. She then presented again to the ED with two weeks of worsening shortness of breath, intermittent fevers (Tmax 101°F), nausea/vomiting, fatigue, and arthralgias.

Cardiovascular: Tachycardia, no m/r/g

Lungs: Coarse breath sounds at bases bilaterally, tachypneic

Abdomen: Soft, non-distended

Skin: Heliotrope rash to face (violaceous, erythematous rash to eyelids and nasolabial fold), shawl sign (erythematous patches to chest and upper back), shallow ulcers to tongue and lower inner lip, tender papules involving palms and lateral fingers bilaterally, and faint erythema of proximal nail fold

ESR: Elevated

LDH: Elevated

CK: Within normal limits

CXR: Bilateral infiltrates

CTPE: Negative for PE, but with scattered areas of ground glass and consolidative opacities throughout both lungs.

Case Question: What is a rare, but highly morbid, autoimmune disorder that may present with skin and pulmonary findings?

If emergency medicine physicians consider MDA5 Dermatomyositis (MDA5 DM) with rapidly progressive interstitial lung disease (RP-ILD) on their differential for patients presenting with skin and pulmonary symptoms, this can result in more rapid diagnosis and aggressive treatment.

This patient was admitted requiring 40 L HFNC, then two days later required intubation for severe ARDS and was placed on VV-ECMO the same day. Her hospital course was complicated by tachyarrhythmias requiring cardioversion, and Takostubo physiology. She was found to be MDA-5 antibody positive and ultimately expired while waiting for a lung transplant.

Case Discussion

Take-Home Points

Critical actions in approaching ED patients with dermatological physical exam findings (even in the absence of known rheumatological history) with progressive pulmonary symptoms should include early consideration of dermatomyositis, serologic testing, early rheumatology and pulmonology consults, and early consideration of ECMO as a bridge to response to immunotherapy or lung transplant
Beginning these critical actions with first patient contact in the ED will only help improve patient outcomes throughout hospitalization.

SAEM Clinical Images Series: More Than Skin Deep

A 57-year-old female college counselor living in the northeastern United States with no PMH presented for evaluation of rash, joint pain, and dyspnea for the past three weeks. The patient first noticed the rash on her upper back, describing it as being itchy. The rash then spread to her face, scalp, and thighs. Two weeks ago, she noticed swelling in her hands and had a gradual onset of dyspnea on exertion. The patient has pain in her hands and when moving her fingers. She denied fever, cough, chills, chest pain, headache, vision changes, focal weakness, abdominal pain, nausea, vomiting, and diarrhea. She denied recent travel, sick contacts, significant time spent outdoors, known tick bites, new medications, and changes in her diet. She has never had a rash like this before.

Case Question: What is the diagnosis and what features of the patient's presentation differentiate her condition from similar diseases?

Amyopathic dermatomyositis – specifically anti-melanoma differentiation-associated gene 5 (anti-MDA5) positive dermatomyositis as determined by subsequent inpatient auto-immunological workup. Compared to other dermatomyositides, anti-MDA5 positive dermatomyositis is characterized by an absence of traditional muscular involvement. Additionally, patients can present with respiratory symptoms related to interstitial lung disease (ILD). One phenotype of this condition is associated with a rapidly progressive ILD, but respiratory involvement may be delayed years after the initial symptoms are noticed. The patient’s clinical images demonstrate a macular, violaceous rash in the “shawl sign” and “holster sign” distribution patterns typical of dermatomyositides. Palmar papules (not to be confused with Gottron’s papules which are found on the dorsal surface of the metacarpophalangeal and interphalangeal joints) are fairly specific for anti-MDA5 positive dermatomyositis

Case Question: What are the next steps in management and treatment of the patient's condition?

There are no specific guidelines for treating anti-MDA5 positive dermatomyositis. Patients are typically started on a high-dose steroid regimen. A rheumatology consult should be obtained to determine if the patient would benefit from treatment with immunosuppressants. Given her complaints of dyspnea, the patient should undergo a non-contrast CT of the chest to evaluate for evidence of scarring or pulmonary fibrosis.

Case Discussion

Take-Home Points

Anti-MDA5 positive dermatomyositis is associated with rapidly progressive ILD has a poor prognosis.
This rare form of dermatomyositis should be suspected if the patient has respiratory complaints in addition to the hallmark cutaneous findings commonly observed in all types of dermatomyositides. Palmar papules are fairly specific for anti-MDA5 positive dermatomyositis. It often lacks typical historical and physical features of muscular weakness.
Treatment involves high-dose corticosteroids and consideration of immunomodulator therapy.

SAEM Clinical Images Series: ‘Tis Not the Season to be Wheezing

A 2-year-old male with a history of solitary kidney presented with greater than one month of daily coughing, wheezing, and decreased appetite. The patient was previously seen by his primary care physician after three weeks of symptoms where he was prescribed albuterol as needed for viral bronchospasm. The patient’s wheezing did not improve after two weeks of albuterol treatment so a chest x-ray was ordered. The patient’s mother denied any fevers, vomiting, diarrhea, weight changes, or night sweats.

Case Question: What is the differential for wheezing in the pediatric patient?

Bronchospasm, bronchiolitis, viral infection, pneumonia, foreign body aspiration, space-occupying lesion, vocal cord dysfunction, cardiac dysfunction, and acute chest in patients with sickle cell disease.

The radiograph shown demonstrates a mediastinal mass. This patient was ultimately diagnosed with T-cell acute lymphoblastic leukemia. T-ALL can present with fatigue, fevers, weight loss, easy bleeding/bruising, paleness, or a mediastinal mass. Mediastinal masses found on chest x-ray require further evaluation to determine the diagnosis, location, and treatment. If malignancy is suspected, an oncology referral and bone marrow sample will be necessary.
