Abstract
Oxygen support with high-flow nasal cannula (HFNC) is gentler than mechanical ventilation and may provide significant benefits, but more studies are needed to investigate the efficacy and safety of different respiratory supports in patients with COVID-19 pneumonia.

Abstract
Spontaneous pneumomediastinum is defined as having an etiology that is not related to surgery, trauma, or mechanical ventilation. Precipitating causes of spontaneous pneumomediastinum include coughing, exercise, vomiting, infection, underlying lung diseases such as asthma, and illicit drugs. Symptoms include chest pain, shortness of breath, and dysphagia. A 54-year-old man presented with 2 weeks of shortness of breath, cough, and fever. He was admitted for severe SARS-CoV-2 pneumonia and acute hypoxic respiratory failure requiring non-rebreather mask. Chest imaging on admission showed bilateral peripheral consolidations and pneumomediastinum with subcutaneous emphysema. No precipitating event was identified. He did not require initiation of positive pressure ventilation throughout his admission. On hospital day 7, chest imaging showed resolution of pneumomediastinum and subcutaneous emphysema, and he was successfully discharged on oxygen therapy. Spontaneous pneumomediastinum is a rare complication of severe acute respiratory syndrome coronavirus 2 infection. Spontaneous pneumomediastinum is typically benign and self-limiting, requiring only supportive treatment.

Abstract
Background: Spontaneous pneumomediastinum (SPM) is an uncommon condition in COVID-19 patients. No information about outcome or risk factors is available at the time. The aim of this research is to report on the frequency and risk factors of spontaneous pneumomediastinum in COVID-19 patients. Materials and Methods: An unmatched case-control study was carried out in a tertiary health-care facility for patients with COVID-19. Electronic files were reviewed to identify patients with confirmed COVID-19 infection by RT-PCR. Univariate analysis was used to describe demographic data. Mean differences were calculated using the Mann-Whitney test. Frequency and odds ratios were calculated by standard operations. Results: A total of 271 patients were included in the study. Nine patients showed spontaneous pneumomediastinum and four of them presented associated spontaneous pneumothorax. The most common risk factors associated with poor outcomes in COVID-19 patients were not considered as risk factors for spontaneous pneumomediastinum development. Conclusion: Spontaneous pneumomediastinum is an uncommon clinical feature in COVID-19 patients. More research is necessary to formulate statements regarding prevalence, risk factors, and outcome.

Abstract
(1) Background: Spontaneous pneumomediastinum (PM), pneumothorax (PT), and pneumopericardium (PP) were recently reported as rare complications in patients with severe COVID-19 pneumonia, and our study aims to follow the evolution of these involvements in 11 cases. The presumed pathophysiological mechanism is air leak due to extensive diffuse alveolar damage followed by alveolar rupture. (2) Methods: We followed the occurrence of PM, PN, PP, and subcutaneous emphysema (SE) in 1648 patients hospitalized during the second outbreak of COVID-19 (October 2020-January 2021) in the main hospital of infectious diseases of our county and recorded their demographic data, laboratory investigations and clinical evolution. (3) Results: Eleven patients (0.66%) developed PM, with eight of them having associated PT, one PP, and seven SE, in the absence of mechanical ventilation. Eight patients (72.72%) died and only three (27.27%) survived. All subjects were nonsmokers, without known pulmonary pathology or risk factors for such complications. (4) Conclusions: pneumomediastinum, pneumothorax, and pneumopericardium are not so uncommon complications of SARS-CoV2 pneumonia, being observed mostly in male patients with severe forms and associated with prolonged hospitalization and poor prognosis. In some cases, with mild forms and reduced pulmonary injury, the outcome is favorable, not requiring surgical procedures, mechanical ventilation, or intensive care stay.

Abstract
Pediatric spontaneous pneumomediastinum is an uncommon condition associated with infection, trauma, or coexisting structural lung pathology. Exercise-related spontaneous subcutaneous emphysema and pneumomediastinum are rarely reported. However, severe pneumomediastinum may coexist with pneumothorax, pneumorrhachis, and subcutaneous emphysema, which can potentially lead to serious complications, including airway obstruction and pneumorrhachis. Therefore, early diagnosis and timely management are important for physicians to determine the etiology and prevent further damage. Here, we present a case of exercise-related spontaneous subcutaneous emphysema and pneumomediastinum to highlight the pathogenesis and suggest therapeutic strategies.

Abstract
H1N1 viral infection leads to complications, such as pneumonia, respiratory failure, myocarditis and encephalitis. Spontaneous pneumomediastinum (SPM) is an extremely rare consequence of H1N1 infection and such cases have been sparsely reported. SPM is identified only by a careful clinical examination and obtaining a timely roentgenogram. We report a case of a young male admitted with H1N1 infection complicated by pneumomediastinum. He was treated successfully with oseltamivir, high-flow oxygen and prompt care in the intensive care unit.

Abstract
Spontaneous pneumomediastinum (SPM) refers to the presence of air in the mediastinum without any obvious cause. It is an uncommon condition occurring due to alveolar rupture as a result of increased intrathoracic pressure. It is commonly seen in young males, patients with known asthmatic disorders and pulmonary diseases. We report a rare case of SPM in a young healthy male without any significant past history. The patient was managed conservatively and discharged.

Abstract
Asthma is the most common chronic respiratory disease worldwide and its prevalence is increasing. Acute asthma complications are often the reason for admission to emergency healthcare service. In our article we present a case of a rare asthma complication – spontaneous pneumomediastinum with a short review of its incidence, etiology, diagnosis and management. Spontaneus pneumothorax is important to differentiate with secondary pneumomediastinum as well as other conditions as cardiac diseases (acute coronary syndrome, pericarditis, cardiac tamponade, pneumopericardium), lung diseases (pneumothorax, pulmonary embolism, tracheobronchial tree rupture), musculoskeletal disorders, and diseases of the esophagus (rupture and perforation o the esophagus). A chest X-ray is often reliable for diagnosis of spontaneous pneumomediastinum and when inconclusive, can be followed by CT. The management is usually conservative with oxygen and analgesia. Surgery is required only in cases of tracheobronchial compression.

Abstract
Pneumomediastinum describes air infiltrating into the soft tissues of the mediastinum. It may be classified as spontaneous or secondary. Spontaneous pneumomediastinum is a rare disease, which usually resolves without intervention. The acute onset of chest pain is the most common presenting complaint. This article presents a case of spontaneous pneumomediastinum in a 19-year-old man with a short history of rapidly enlarging, painless swelling to the left side of his neck, followed by a discussion of the literature. The diagnosis was made following chest x-ray (CXR) and computed tomography (CT). There was no history of any precipitating event or any risk factors. He was managed conservatively and discharged with outpatient follow-up. Management of spontaneous pneumomediastinum continues to vary and may benefit from the development of guidelines to standardise management in the future.

Abstract
Spontaneous pneumomediastinum is an uncommon diagnosis defined as the presence of free air in the mediastinum without an apparent cause. It is a self-limiting disorder that most often occurs in young males without any apparent precipitating factor or underlying disease process. Its pathophysiology involves the rupture of alveoli with resultant air penetration into the mediastinum. Underlying disease processes, such as asthma, physical trauma, including yelling, contact sports, and Valsalva during labor, have also been reported to cause spontaneous pneumomediastinum. Here, we present the case of an 18-year-old male who presented to us with the chief complaint of cough and the subsequent diagnosis of spontaneous pneumomediastinum.

Abstract
Pneumomediastinum is defined as the presence of air in the mediastinum. Trauma to the nearby organs can cause air to escape into surrounding tissues that may manifest clinically as severe chest pain, voice change, or shortness of breath. However, pneumomediastinum can present spontaneously in healthy individuals with no inciting factors in which case the condition is termed spontaneous pneumomediastinum (SPM). Pneumomediastinum can be challenging to manage due to the absence of clear guidelines for the diagnosis and management. We present the case of a 21-year-old with no previous medical history who presented with chest pain that was aggravated by speech and breath. The pain was of sudden onset preceded by smoking at 2:00 am. The patient was tachycardic, tachypnoeic with crepitation on palpation and a crunch sound (Hamman’s sign) on auscultation. The patient rated the pain as 5/10 on a 11-point numerical pain rating scale, which then evolved to 10/10. The patient did not have fever, loss of consciousness (LOC), diaphoresis, history of trauma, or previous similar presentation. There were no other associated symptoms. A chest X-ray (posteroanterior (PA) and lateral view) showed pneumomediastinum, but laboratory tests results were otherwise normal. The patient was observed in the emergency room overnight. He remained stable, his tachycardia settled, and there was no leukocytosis or desaturation; however, tachypnea was observed. His pain symptoms were treated with analgesia as needed and the patient was discharged home in a stable condition, to be followed on an outpatient basis. Spontaneous pneumomediastinum can be challenging to manage due to the lack of reliable incidence data as well as the absence of clear management guidelines. Further research will aid in understanding the true incidence of SPM in Saudi Arabia and help in establishing a consensual approach and treatment guidelines to deal with SPM in otherwise healthy individuals. To the best of our knowledge, this is the first case of SPM in a young male reported from a tertiary hospital in Riyadh, Saudi Arabia.

Abstract
Introduction Inhaled marijuana has been infrequently identified as a potential risk factor for the development of spontaneous pneumomediastinum (SPM), a rare finding of free air in the mediastinum likely caused by barotrauma during breathing manoeuvres. The mechanism of inhalation drug use is often not ascertained by physicians, thus little is known about how different smoking techniques precipitate pulmonary injury. We aimed to evaluate the frequency of marijuana use in patients with non-traumatic pneumomediastinum over a 12-month period, identifying additional relevant clinical features or risk factors, and determining the extent to which clinicians record smoking techniques. Methods We performed a retrospective chart review over a 1-year period, identifying patients presenting to the hospital with a diagnosis of pneumomediastinum in the absence of trauma, malignancy or iatrogenic cause. Results We identified 21 cases, 14 of which (66.7%) were associated with marijuana use, average age was 22.5 years (range 18–30), with male predominance (64.2%). Daily or more use was reported in 50% of cases. Concurrent risk factors including vomiting (57.1%) and coughing (42.9%) were commonly present. The mechanism of smoking was described in only two cases (14.3%). Discussion Inhaled marijuana may be an underappreciated risk factor for the development of SPM, caused by air leakage around the bronchovascular sheaths during successive inhalation through a high-resistance smoking apparatus or forced exhalation against a closed glottis. Physicians should be aware of this association in order to provide appropriate counselling. Further research is needed to direct the safe use of smoking devices and techniques.

Abstract
Tracheostomy is a common procedure seen in critically ill patients that require long term ventilatory support. As with all airway access procedures, tracheotomy with prolonged tracheal tube placement comes with possible risks such as tracheal scarring, tracheal rupture, pneumothorax, tracheoesophageal fistula among others. Another possible complication, though rare, is escape of free air into the surrounding tissue, as well as pneumomediastinum (PM). This may occur due to various reasons, some of them being tracheal rupture, barotrauma or tracheal tube mispositioning. Pneumomediastinum may present with concurrent free air in other body cavities such as the peritoneum, thorax or subcutaneous tissue. Though often not life-threatening it may require treatment including high flow oxygen, ventilator management or occasionally, surgical intervention. Herein we describe a rare case of PM with communicating pneumoperitoneum and massive subcutaneous emphysema due to tracheal tube mispositioning along with a review of the literature.

Abstract
Spontaneous pneumomediastinum (SPM), also referred to as mediastinal emphysema, is defined as the presence of free air in the mediastinal cavity without a clear and identifiable cause. Spontaneous pneumomediastinum, in general, is a relatively rare condition, more so in the setting of pregnancy or labor. Clinically, SPM may present as dyspnea, chest pain, and subcutaneous swelling, which may be of serious concern in the setting of pregnancy. A comprehensive literature review revealed that the majority of patients are primiparas, of a younger age, and have term or longer durations of pregnancy. The second stage of labor was found to be most commonly associated with the development of SPM. The pathomechanism suggests that performing the Valsalva maneuver during the active stages of labor may play a role in the development of SPM. Once diagnosed, patients with SPM in pregnancy are admitted to the hospital, treated conservatively, and followed until resolution. SPM must be diagnosed and managed promptly due to rare but serious complications. In addition, dyspnea or chest pain with an unknown etiology should include SPM in the differential diagnosis, especially in the setting of pregnancy and labor.

Abstract
Playing musical instruments can bring joy to people, but can also cause a wide variety of health issues that range from mild disorders to potentially fatal conditions. Although sports medicine is an established medical subspecialty, relatively few studies have investigated the health issues associated with musical instruments. Here we present an overview of these health issues. These include infections due to microorganisms, allergic reactions, as well as mechanical injuries from sustained high pressures within the oral, mediastinal, thoracic, and abdominal cavities. For example, wind instruments can potentially harbor thousands of pathogenic organisms. If several players share the same instrument, these instruments present potential hazards in the spread of infections. A fatal case of hypersensitivity pneumonitis in a bagpiper is particularly noteworthy. Similarly, a case of gastrointestinal anthrax in an animal-hide drummer is a reminder of this rare but highly fatal disease. Although not fatal, hearing-related disorders, neuromuscular issues, musculoskeletal problems, and contact dermatitis are also very common among instrumentalists. This review aims to illuminate these under-recognized health issues by highlighting both the common conditions and the rare but fatal cases.

Abstract
Spontaneous pneumomediastinum is a benign, self‐limited condition that mainly affects young people. In this report, we present four cases of this uncommon condition and a review of the current literature. Two cases had no prior significant medical history: one had a history of asthma and the other underwent regular outpatient treatment for anorexia nervosa. The three patients who were not anorexic spontaneously improved within a few days. However, the patient with anorexia nervosa took 2 months to recover. It appears that spontaneous pneumomediastinum is an intractable complication of anorexia nervosa, and the improvement of nutritional status in the patient is essential to manage this condition.

Abstract
Although extraintestinal manifestations of inflammatory bowel diseases are not uncommon, few reports have described concurrent idiopathic thrombocytopenic purpura (ITP). Spontaneous pneumomediastinum is also a rare complication of ulcerative colitis (UC). This report describes the case of a 14-year-old boy who experienced recurrent ulcerative colitis 3 months after temporary improvement following treatment with prednisolone (20 mg/day) and granulocyte/monocyte adsorption apheresis. His platelet counts decreased, suggesting ITP. The dosage of prednisolone was increased to 60 mg/day; however, his thrombocytopenia did not improve and he suddenly developed pneumomediastinum. A continuous infusion of cyclosporine increased his platelet counts and improved his ulcerative colitis. Cyclosporine should be considered when steroid-resistant ITP accompanies UC.

Abstract
Background There are no previous reports regarding the computed tomography (CT) findings of subpleural pulmonary interstitial emphysema (PIE) in patients with spontaneous pneumomediastinum. Purpose To evaluate CT findings of subpleural PIE that may indicate a direct site of terminal alveolar rupture. Material and Methods We retrospectively evaluated chest CT and the medical records of 34 patients with spontaneous pneumomediastinum. Subpleural PIE was defined as the presence of an interstitial air collection in the subpleural portion of the lungs excluding the bronchovascular bundle. Results Subpleural PIE on CT was identified in six of 34 patients (17.6%) with spontaneous pneumomediastinum. In four of these (66.7%), subpleural PIE was present in multiple lobes suggesting multiple simultaneous ruptures of terminal alveoli. The shape of subpleural PIE was elongated linear (4/6), branching and linear (1/6), and elliptical (1/6). Conclusion The presence of subpleural PIE on CT suggests an origin of pneumomediastinal air from alveolar rupture.

Abstract
Background: Spontaneous pneumomediastinum (SPM) is an uncommon disorder. It is rarely
reported in paediatric patients and may be accompanied by subcutaneous
emphysema. It is usually benign and self-limiting, with only supportive
therapy being needed, but severe cases may require invasive measures. Asthma
exacerbations have classically been described as a cause of SPM. However,
detailed descriptions in asthmatic children are scarce. We aimed at
improving the current understanding of the features of SPM and subcutaneous
emphysema, and outcomes, by means of a case report and a systematic
review. Methods: For the systematic review a literature search was performed in PubMed to
identify reported cases of SPM in asthmatic children. Results: The case a 10-year-old asthmatic girl with SPM is reported. The patient
received an inhaled corticosteroid and long-acting beta2 agonist, in
addition to sublingual immunotherapy (SLIT) with eventual control of asthma
symptoms. Review: A total of 114 published cases were found since 1995, most
of them in teenagers; no sex differences were observed. Clinical
presentation was associated with an asthma exacerbation in a number of
cases. Other presenting features were chest pain, dyspnoea, cough, and
particularly acute swelling of the face, neck, and upper chest. Subcutaneous
emphysema was present in most patients. Overall, three cases of pneumothorax
and two cases of pneumorrhachis were reported. Therapy was mainly based on
supportive care, rest, oxygen therapy, analgesics, steroids, and
bronchodilators. All patients recovered spontaneously, in spite of a small
initial increase in SPM in a few cases. Conclusions: Early identification of patients at risk of SPM would avoid the high number
of under-diagnosed cases. Patients should be treated not only with
supportive therapy but also with measures to achieve control of the
underlying cause (such as poorly controlled asthma).

Three Simultaneous Cases of Spontaneous Pneumomediastinum With Epidural Pneumatosis During Vocal Training. J Voice 2016; 31:263.e1-263.e3. [PMID: 27423821 DOI: 10.1016/j.jvoice.2016.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2016] [Accepted: 04/12/2016] [Indexed: 11/23/2022]
Abstract
OBJECTIVE The aim of this study was to describe a case series of three simultaneous cases of spontaneous pneumomediastinum (SPM) with epidural pneumatosis during vocal training. METHODS A report of three cases with chart review was performed. Literature review was carried out using PubMed. RESULTS This was an extremely rare case series where at least three of the 20 participants of a vocal training in a self-development seminar developed SPM, epidural pneumatosis, pneumothorax, and subcutaneous emphysema. All cases improved with bed rest. Simultaneous cases of SPM have been reported in the past. However, the cause of simultaneous occurrence has not been explained clearly. In our cases, continuous excessive vocal training may have caused intrathoracic pressure to rise, causing SPM at a high prevalence. Epidural pneumatosis is a rare finding. Studies on epidural pneumatosis complicating SPM are limited. Air is said to easily pass through the cervical region owing to the close proximity between the mediastinum and the upper spine, resulting in epidural pneumatosis. Elevated intrathoracic pressure while the glottis is closed may worsen the risk for epidural pneumatosis. In this seminar, continuous effortful vocal training at full pitch with few pauses for breath may have contributed to this simultaneous occurrence. CONCLUSIONS We report three simultaneous cases of SPM and epidural pneumatosis due to demanding vocal training. Further research on this subject is desired to identify risk factors.

Abstract
A 1.5-year-old, 23 kg intact male Dalmatian dog was evaluated for acute respiratory insufficiency without a previous history of trauma or toxic exposition. Imaging revealed pneumomediastinum, pneumothorax, diffuse unstructured interstitial pulmonary pattern, pulmonary interstitial emphysema, and pneumoretroperitoneum. Histopathological evaluation of the lungs revealed perivascular and peribronchial emphysema, mild lymphocytic interstitial pneumonia with atypical proliferation of type II pneumocytes in bronchioles and alveoli. A lung disease resembling fibrosing interstitial pneumonia in man and cats has been previously reported in Dalmatians and should be included as a differential diagnosis for Dalmatians with this combination of clinical and imaging characteristics.

Abstract
OBJECTIVE This study aimed to investigate the benignancy of primary spontaneous pneumomediastinum (PSP), and to establish an appropriate management strategy. METHODS Patients diagnosed with PSP between January 2003 and December 2013 were analysed retrospectively. From January 2013 onwards, a simplified protocol, with consensus for the management of PSP, was applied in our hospital. RESULTS In total, 37 patients were identified as having PSP during the study period. Among them, 27 were enrolled prior to applying the new protocol. Among these patients, extra diagnostic tests, in addition to chest radiography (CXR) and chest computed tomography (CT), were performed in 15 patients (55.5%). In the pre-protocol decade, a total of 15 patients (55.5%) were initially fasted and 16 (59.3%) were administered antibiotics. Mean hospital stay was 2.9 days (range, 0-5 days). No patient developed complications during the hospital stay and outpatient follow up. Since the revised protocol was in practical use, 10 consecutive patients with PSP were enrolled and reviewed. No additional diagnostic imaging studies or procedures (except for CXR and chest CT) were performed in these patients; furthermore, diet was not restricted and prophylactic antibiotics were not prescribed. Mean hospital stay was 14.5 h (range, 1-34 h). No complications were observed in any of the patients. CONCLUSIONS Our management protocol (i.e. routine check of chest CT without any additional diagnostic tests, no special treatment, and early discharge with short-term follow up) may be safe and feasible for the treatment of PSP.
