Spontaneous pneumomediastinum--'ectasy': a hard pill to swallow

Spontaneous Pneumomediastinum and Subcutaneous Emphysema following Cocaine Inhalation and Ecstasy Ingestion

Spontaneous pneumomediastinum (SPM) and subcutaneous emphysema are rare complications of illicit drug abuse. Thorough history, examination, and investigations are required to rule out fatal complications such as oesophageal perforation. We present a case of a 21-year-old male presenting with pleuritic chest pain one day after cocaine inhalation and ingesting ecstasy. Conservative supportive management is appropriate when this occurs spontaneously without radiological evidence of visceral perforation.

Extensive subcutaneous emphysema and pneumomediastinum after ecstasy ingestion

Objective. To present a rare case of extensive subcutaneous emphysema and spontaneous pneumomediastinum following ingestion of Ecstasy in a young adult. We also review the relevant literature and discuss how this case supplements it. Case Report. We report a case of a 19-year-old man with a history of painless neck and chest swelling, and no chest pain or breathlessness, after consuming Ecstasy tablets. Radiological imaging showed evidence of pneumomediastinum and extensive subcutaneous emphysema. The patient remained well under observation and his symptoms improved with conservative management. Conclusions. Subcutaneous emphysema and pneumomediastinum after Ecstasy ingestion is uncommon. Cases are often referred to the otolaryngologist as they can present with neck and throat symptoms. Our case showed that the severity of symptoms may not correlate with severity of the anatomical abnormality and that pneumomediastinum should be suspected in Ecstasy users who present with neck swelling despite the absence of chest symptoms. Although all cases reported so far resolved with conservative management, it is important to perform simple investigations to exclude coexisting serious pathology.

Spontaneous pneumomediastinum presenting as rhinolalia and chest pain

This report discusses a case of spontaneous pneumomediastinum in a 25-year-old medical student. The patient presented with chest pain and a tonal change in voice. Symptoms occurred after an episode of stretching and were exacerbated by coughing. There was no history of underlying respiratory disease and he was a non-smoker. Management was conservative. At the four-week follow-up appointment, bronchoscopy and computed tomography of the thorax demonstrated complete resolution. Spontaneous pneumomediastinum is uncommon, with rhinolalia being a rare presenting feature. It should be considered as a differential diagnosis in patients with chest pain associated with a change in voice. A detailed history may reveal preceding activities associated with raised intrathoracic pressure.

Two case reports of pneumomediastinum

BACKGROUND

We present two cases of pneumomediastinum in patients who presented to the accident and emergency department of a large teaching hospital. One case had a history of inhalational drug abuse, which may have contributed to the event, while the other had no obvious precipitating factors.

AIMS

To evaluate the presenting symptoms, physical signs, diagnosis and management of pneumomediastinum with a review of the literature.

METHODS

We describe two cases of pneumomediastinum with a literature review.

CONCLUSIONS

Pneumomediastinum is an uncommon entity, first described almost 400 years ago. It presents with relatively non-specific symptoms and signs and will require radiological investigations to clarify the diagnosis. Treatment is conservative but will require close observation for the development of complications and occult visceral perforation. Complete resolution can be expected.

Ecstasy-associated pneumomediastinum

INTRODUCTION

Ecstasy, also known as MDMA (3,4, methylenedioxymethamphetamine), is a popular illicit party drug amongst young adults. The drug induces a state of euphoria secondary to its stimulant activity in the central nervous system.

PATIENTS AND METHODS

A database review at two major inner city hospitals was undertaken to identify patients presenting with pneumomediastinum and their charts reviewed. A Medline review of all reported cases of pneumomediastinum associated with ecstasy abuse was undertaken.

RESULTS

A total of 56 patients presenting with pneumomediastinum were identified over a 5-year period. Review of the charts revealed a history of ecstasy use in the hours prior to presentation in six of these patients, representing the largest series reported to date.

CONCLUSIONS

Review of previously reported cases reveals the likely mechanism is due to Valsalva manoeuvre during periods of extreme physical exertion, and not a direct pharmacological effect of the drug.

Spontaneous pneumomediastinum: a benign curiosity or a significant problem?

OBJECTIVE

To identify the significance of spontaneous pneumomediastinum (SPM) and to optimize its management.

METHODS

A retrospective analysis was undertaken of all patients presenting with SPM over a 5-year period. Eighteen patients were identified, and information on their presentations, initial diagnoses, comorbidities, investigations, clinical courses, length of hospital stays, and outcomes were collated.

SETTING

The emergency department referrals of two major Melbourne teaching hospitals.

RESULTS

SPM is an uncommon condition presenting in approximately 1 in 30,000 emergency department referrals. The typical patient identified from this study is a young man who is likely to have a history of asthma, and who is also likely to smoke or to use illicit drugs. The most common presentation is nonspecific pleuritic chest pain with dyspnea. Complications are rare, and the clinical course benign, but the possibility of a ruptured viscus or an initial misdiagnosis often leads to a great number of investigations. A proposed algorithm of management is given. Other serious and potentially life-threatening conditions, such as Boerhaave syndrome need to be excluded.

Spontaneous pneumomediastinum and myocarditis following Ecstasy use: a case report

Ecstasy is a very popular and widely used party drug with known complications such as agitation, hyperpyrexia, rhabdomyolysis or renal failure. A 16-year-old boy was admitted to our Emergency Department with a spontaneous pneumomediastinum (SPM) after Ecstasy ingestion, complicated by myocarditis. To our knowledge this is the first case described with the combination of Ecstasy ingestion, SPM and myocarditis. Although SPM is well known in inhalation drug users who try to enhance alveolar resorption with repeated valsalva manoeuvres, it is rather rare after the ingestion of party drugs. The probable causative event is the prolonged and excessive dancing in this party drug culture. The course is usually benign, with spontaneous resorption. Emergency physicians should be aware of the risk, especially if a drug user presents with neck emphysema, difficulty in swallowing, and precordial crepitations or thoracic pain. Ecstasy, similarly to cocaine, can induce cardiac symptoms.

[Pneumomediastinum as a complication of recreational ecstasy use]

Ecstasy recreational use dramatically increased during the last decade in France. Multiples complications associated with ecstasy consumption have been reported. We describe an exceptional case of pneumomediastinum related to ecstasy recreational use. The patient was a 19-year old patient whose medical history was significant for asthma and was a moderate tobacco smoker. He reported regular ecstasy recreational use. He presented at the emergency unit for chest pain and cough, 48 hours after the ingestion of three tablets of ecstasy and the inhalation of three other tablets. Blood pressure was 90/60 mmHg, pulse rate was 120 per minute, respiratory rate was 32 per minute and pulse oximetry was 93%. Neck emphysema was noted. Chest radiograph and scanner diagnosed pneumomédiastinum. Outcome was favorable with symptomatic treatment and the patient was discharged home eight days later. Pneumomediastinum is an exceptional complication after ecstasy recreational use. Physician should be aware of the risk of such event.
