Resumen Introducción: El neumomediastino se define como la presencia de aire o gas dentro de los planos fasciales del mediastino. Por lo general, es un fenómeno secundario a perforaciones traumáticas del tracto aerodigestivo. El neumomediastino secundario a una fractura orbitaria es un evento raro. Se asocia a complicaciones potencialmente mortales como el neumotórax, el neumopericardio y la mediastinitis. Objetivo: Describir un caso de neumomediastino secundario a una fractura aislada de piso orbitario y su manejo médico-quirúrgico. Caso clínico: Paciente de sexo femenino de 42 años que sufre traumatismo en regiones facial, cervical y torácica desarrollando secundariamente un enfisema subcutáneo panfacial y un neumomediastino, el cual se resuelve exitosamente. Discusión: El neumomediastino secundario a una fractura aislada de piso orbitario es un evento muy raro. El aire puede descender a lo largo de los espacios fasciales hasta el mediastino. En este sentido, sonarse la nariz es un factor de riesgo para desarrollar esta pa-tología. Conclusión: Ocurrido un trauma maxilofacial puede presentarse enfisemas de espacios profundos de la cabeza, cuello e incluso el mediastino.
Introduction: Pneumomediastinum is defined as the presence of air or gas within the fascial planes of the mediastinum. It is usually a phenomenon secondary to traumatic perforations of the aerodigestive tract. Pneumomediastinum secondary to an orbital fracture is a rare event. And it is related to life-threatening complications such as pneumothorax, pneumopericardium and mediastinitis. Aim: To describe a case of pneumomediastinum secondary to an isolated orbital floor fracture and its medical-surgical management. Clinical case: A 42-year-old female patient who suffers trauma to the facial, cervical and thoracic regions, secondary development of a subcutaneous panfacial emphysema and pneumomediastinum, which resolves successfully. Discussion: Pneumomediastinum following an isolated orbital floor fracture is a very rare event. The air can descend along the fascial spaces to the mediastinum. In this sense, blowing your nose is a risk factor to develop this pathology. Conclusion: After a maxillofacial trauma, emphysema of the deep spaces of the head, neck and even the mediastinum can occur

Resumen El neumomediastino espontáneo es la presencia de aire libre en el mediastino sin el antecedente de alguna causa como trauma de tórax. Es una condición benigna autolimitada que se trata en forma conservadora. El diagnóstico clínico se basa en dos síntomas: dolor torácico y disnea; y en un signo en particular: enfisema subcutáneo. Ha sido reportado en pacientes con influenza A (H1N1) y síndrome respiratorio agudo grave; sin embargo, ha sido raramente observado en pacientes con COVID-19. En este trabajo describimos seis pacientes del sexo masculino con COVID-19, con edades entre 27 y 82 años, que presentaron neumomediastino espontáneo y enfisema subcutáneo; ambos se reabsorbieron totalmente con manejo conservador.
Abstract Spontaneous pneumomediastinum is defined as the presence of free air within the mediastinum without an apparent cause such as chest trauma. It is a benign, self-limiting condition that is conservatively treated. Clinical diagnosis is based on two symptoms: chest pain and dyspnea; and on a particular sign: subcutaneous emphysema. It has been reported in patients with influenza A (H1N1) and severe acute respiratory syndrome; however, it has been rarely observed in COVID-19 patients. In this work, we describe six male patients with COVID-19, aged between 27 and 82 years, who presented with spontaneous pneumomediastinum and subcutaneous emphysema; both conditions were completely resorbed with conservative management.

OBJECTIVES: To evaluate the presentation characteristics and disease course of seven patients with COVID-19 who spontaneously developed pneumomediastinum without a history of mechanical ventilation. METHODS: A total of seven non-intubated patients with COVID-19, of age ranging from 18-67 years, who developed spontaneous pneumomediastinum between 01 April and 01 October 2020 were included in the study. Patients' demographic data, clinical variables, and laboratory values were examined. Spontaneous pneumomediastinum was evaluated using posteroanterior chest radiography and thorax computed tomography. RESULTS: During the research period, 38,492 patients reported to the emergency department of our hospital with COVID-19 symptoms. Of these, spontaneous pneumomediastinum was detected in seven patients who had no previous history of intubation. Chronic obstructive pulmonary disease (2/7) and asthma bronchiale (2/7) were determined as the most common causes of comorbidity. CONCLUSIONS: In our study, the frequency of spontaneous pneumomediastinum developing without pneumothorax was found to be high in non-intubated patients. Whether this is related to the nature of the disease or it is a result of the increase in cases diagnosed incidentally owing to the increasing use of low-dose computed tomography should be explored in further studies.

OBJECTIVES: To describe a case series of spontaneous pneumomediastinum in dermatomyositis and to review the literature. METHODS: This was a retrospective single-center case series, reporting 9 patients with pneumomediastinum and defined dermatomyositis, followed from 2005 to 2017. RESULTS: Median age of patients: 33 years; cutaneous and pulmonary involvement in all cases; constitutional symptoms in 88.8% of patients; involvement of the joints in 11.1%, gastrointestinal tract in 44.4%, and muscles in 77.7%; subcutaneous emphysema was observed in 55.5% and pneumothorax in 11.1%, respectively. Muscle weakness was observed in 77.7% of cases and with a median level of serum creatine phosphokinase of 124U/L. Drawing on results for our literature review, the overall analysis showed that the risk factors associated with spontaneous pneumomediastinum were: (a) a history of interstitial pneumopathy; (b) normal or low levels of muscle enzymes; (c) previous use of systemic glucocorticoid; (d) over 50% of patients had subcutaneous emphysema; (e) high mortality as a consequence of severity of the interstitial lung disease. CONCLUSIONS: Our case series revealed that pneumomediastinum is a rare complication in dermatomyositis that occurs in patients with a history of interstitial pneumopathy and may be accompanied by subcutaneous emphysema and pneumothorax.
OBJETIVOS: Descrever série de casos de pneumomediastino espontâneo em portadores de dermatomiosite e revisar a literatura. MÉTODOS: Trata-se de série de casos, único centro, relatando 9 pacientes com pneumomediastino e dermatomiosite definida, acompanhados de 2005 a 2017. RESULTADOS: A mediana da idade dos pacientes foi de 33 anos. Sintomas constitucionais estavam presentes em 88,8% dos pacientes. Houve acometimento cutâneo e pulmonar em todos os casos, acometimento das articulações em 11,1%, trato gastrointestinal em 44,4% e musculatura em 77,7% dos pacientes. Enfisema subcutâneo foi observado em 55,5% e pneumotórax em 11,1%, respectivamente. A fraqueza muscular foi observada em 77,7% dos casos, com um nível médio de creatinofosfoquinase sérica de 124U/L. Com base nos resultados da revisão da literatura, a análise geral mostrou que: os fatores de risco associados ao pneumomediastino espontâneo foram: história de pneumopatia intersticial, níveis normais ou baixos de enzimas musculares, uso prévio de glicocorticoide sistêmico; >50% dos pacientes tiveram enfisema subcutâneo; houve alta mortalidade como consequência da gravidade da doença pulmonar intersticial. CONCLUSÕES: Nossa série de casos revelou que o pneumomediastino é uma complicação rara na dermatomiosite e que ocorre em pacientes com história de pneumopatia intersticial e pode ser acompanhada por enfisema subcutâneo e pneumotórax.

Mujer de 68 años que ingresa en la Unidad de Cuidados Intensivos por shock séptico. En el posoperatorio la paciente se mantiene inestable y se decide realizar traqueotomía percutánea (TP) por intubación prolongada. Al inicio la paciente presenta un enfisema subcutáneo que progresa hasta convertirse en masivo. Se realiza TC torácico donde se observa pérdida de la morfología habitual de la pared posterior traqueal con solución de continuidad. Tras revisión mediante traqueobroncoscopía se decide colocar cánula de traqueotomía larga para dejar la lesión proximal al neumotaponamiento y así evitar la fuga de aire. Desde la colocación de la nueva cánula, la paciente presenta una disminución progresiva del enfisema hasta su total resolución. La TP es un procedimiento seguro que se realiza con mucha frecuencia en los servicios de medicina intensiva, sin embargo, no está exenta de complicaciones. En la revisión de Powell y cols describen las complicaciones de la TP destacando la inserción peritraqueal, la hemorragia, las infecciones de la herida, el neumotórax y la muerte. El rango de complicaciones en la literatura oscila entre 3% y 18%. Además, no se encuentran diferencias significativas respecto a las complicaciones entre la TP y la técnica abierta.
A 68-year-old woman who enter in intensive care unit due to septic shock. In the postoperative period, the patient remained unstable and decided to perform a percutaneous tracheotomy (PT) because prolonged intubation. In the first, the patient presents subcutaneous emphysema that progresses until becoming massive. Thoracic CT is performed where loss of the usual morphology of the posterior tracheal wall with continuity solution is observed. After revision by means of tracheobroncoscopia, it is decided to place a long tracheotomy cannula to leave the lesion proximal to pneumotaponamiento and thus avoid air leakage. From the placement of the new cannula, the patient presents a progressive decrease of the emphysema until its total resolution. PD is a safe procedure that is performed very frequently in the Intensive Care Services3, however, it is not without its complications. The review of Powell et al4 describes the complications of PT emphasizing peritracheal insertion, hemorrhage, wound infections, pneumothorax, and death. The range of complications in the literature ranges from 3 to 18% 5. In addition, no significant differences were found regarding the complications between the TP and the open technique.

ABSTRACT Objective: To characterize clinically all of the patients with spontaneous pneumomediastinum (SPM) admitted to an adult pulmonology ward in Lisbon, Portugal. Methods: This was a retrospective descriptive study of all adult patients (≥ 18 years of age) diagnosed with SPM between January of 2004 and September of 2015. Results: At least one predisposing factor was identified in most (88.9%) of the 18 patients who presented with SPM during the study period. With regard to precipitating factors, bouts of cough were present in 50.0% of the patients. Other precipitating factors included a sudden increase in tobacco consumption, inhaled drug use, occupational inhalation of varnish fumes, intense exercise, and vomiting. The most common complaints were dyspnea (in 83.3%) and chest pain (in 77.8%). Other complaints included cough, neck pain, dysphagia, and odynophagia. Subcutaneous emphysema was found in most of the patients. The diagnosis of SPM was based on chest X-ray findings in 61.1% of the patients. Conclusions: Although SPM is a rare condition, it should be considered in the differential diagnosis of chest pain and dyspnea. It can develop without a triggering event or conclusive findings on a chest X-ray, which is usually sufficient for diagnosis.
RESUMO Objetivo: Caracterizar clinicamente todos os pacientes com pneumomediastino espontâneo (PME) admitidos em uma enfermaria de pneumologia para adultos em Lisboa, Portugal. Métodos: Estudo descritivo retrospectivo no qual foram analisados todos os pacientes adultos (≥ 18 anos de idade) com diagnóstico de PME entre janeiro de 2004 e setembro de 2015. Resultados: Pelo menos um fator predisponente foi identificado na maioria (isto é, em 88,9%) dos 18 pacientes que apresentaram PME durante o período de estudo. No tocante a fatores precipitantes, crises de tosse ocorreram em 50,0% dos pacientes. Outros fatores precipitantes foram um aumento repentino do consumo de tabaco, uso de drogas inalatórias, inalação ocupacional de vapores de vernizes, exercício intenso e vômitos. As queixas mais comuns foram dispneia (em 83,3%) e dor torácica (em 77,8%). Outras queixas foram tosse, cervicalgia, disfagia e odinofagia. Constatou-se a presença de enfisema subcutâneo na maioria dos pacientes. O diagnóstico de PME baseou-se na radiografia de tórax em 61,1% dos pacientes. Conclusões: Embora seja uma doença rara, o PME deve ser levado em conta no diagnóstico diferencial de dor torácica e dispneia. O PME pode surgir sem um evento desencadeante e sem achados conclusivos na radiografia de tórax, que é geralmente suficiente para o diagnóstico.

Introducción. La presión positiva continua en la vía aérea ( Continuous Positive Airway Pressure , CPAP) es útil en prematuros de 28 a 32 semanas de gestación con síndrome de dificultad respiratoria, pero no se ha precisado si es mejor que la respiración mecánica asistida después de la administración precoz de surfactante pulmonar. Objetivo. Comparar la incidencia de eventos adversos en prematuros de 28 a 32 semanas de gestación con síndrome de dificultad respiratoria atendidos con surfactante y respiración mecánica asistida o CPAP de burbuja. Materiales y métodos. Se atendieron 147 neonatos con respiración mecánica asistida y 176 con CPAP, ninguno de los cuales presentaba asfixia perinatal o apnea. Resultados. La incidencia de fracaso de la CPAP fue de 6,5 % (IC 95% 11,3-22,8 %). Fallecieron 29 pacientes, 7 de los cuales habían recibido CPAP (4,0 %) y, 22, respiración mecánica asistida (15,0 %; p<0,001). El riesgo relativo (RR) de morir de quienes recibieron CPAP, comparado con el de quienes recibieron respiración mecánica asistida, fue de 0,27 (IC 95% 0,12-0,61), pero, al ajustar por los factores de confusión, el uso de CPAP no implicó mayor riesgo de morir (RR=0,60; IC 95% 0,29-1,24). La letalidad con respiración mecánica asistida fue de 5,70 (IC 95% 3,75-8,66) muertes por 1.000 días-paciente, mientras que con CPAP fue de 1,37 (IC 95% 0,65-2,88; p<0,001). La incidencia de neumopatía crónica fue menor con CPAP (RR=0,71, IC 95% 0,54-0,96), al igual que la de hemorragia cerebral (RR=0,28; IC 95% 0,09-0,84) y la de sepsis (RR=0,67; IC 95% 0,52-0,86), pero fue similar en cuanto a escapes de aire (RR=2,51; IC 95% 0,83-7,61) y enterocolitis necrosante (RR=1,68; IC 95% 0,59-4,81). Conclusión. La incidencia de neumopatía crónica, hemorragia ventricular y sepsis es menor con el uso de CPAP.
Introduction: Continuous positive airway pressure (CPAP) is useful in low birth weight infants with respiratory distress, but it is not known if it is a better alternative to mechanical ventilation after early pulmonary surfactant administration. Objective: To compare the incidence of adverse events in 28 to 32-week newborns with respiratory distress managed with mechanical ventilation or CPAP after early surfactant administration. Materials and methods: In total, 176 newborns were treated with CPAP and 147 with mechanical ventilation, all with Apgar scores >3 at five minutes and without apnea. Results: The incidence of CPAP failure was 6.5% (95% CI: 11.3-22.8%); 29 patients died: 7 with CPAP (4.0%) and 22 with mechanical ventilation (15.0%, p<0.001). The relative risk of dying with CPAP versus mechanical ventilation was 0.27 (95% CI: 0.12-0.61), but after adjusting for confounding factors, CPAP use did not imply a higher risk of dying (RR=0.60; 95% CI: 0.29-1.24). Mechanical ventilation fatality rate was 5.70 (95% CI: 3.75-8.66) deaths/1,000 days-patient, while with CPAP it was 1.37 (95% CI: 0.65-2.88, p<0.001). Chronic lung disease incidence was lower with CPAP than with mechanical ventilation (RR=0.71; 95% CI: 0.54-0.96), as were intracranial hemorrhage (RR=0.28, 95% CI: 0.09-0.84) and sepsis (RR=0.67; 95%CI: 0.52-0.86), and it was similar for air leaks (RR=2.51; 95% CI: 0.83-7.61) and necrotizing enterocolitis (RR=1.68, 95% CI: 0.59-4.81). Conclusion: CPAP exposure of premature infants with respiratory distress syndrome is protective against chronic lung disease, intraventricular hemorrhage and sepsis compared to mechanical ventilation. No differences were observed regarding air leak syndrome or death.

O presente estudo descreve uma paciente de 41 anos de idade com dermatomiosite, doença pulmonar intersticial e vasculopatia cutânea que desenvolveu pneumomediastino. Durante exame de broncoscopia foram encontradas lesões pálidas na laringe, que se estendiam para a árvore traqueobrônquica, e úlceras profundas na parede membranácea da traqueia. O exame histopatológico revelou presença de processo inflamatório secundário à vasculite, mas sem sinais de infecção. Lesões nas vias aéreas superiores e inferiores em paciente com dermatomiosite são raríssimas. A associação de dermatomiosite com úlceras profundas de mucosa e pneumomediastino não está bem esclarecida, mas a broncoscopia é um exame que deve ser utilizado para aperfeiçoar a avaliação.
We described a 41-year-old woman with dermatomyositis, interstitial lung disease, and cutaneous vasculopathy who developed a pneumomediastinum. The routine bronchoscopy investigation found pale lesions in the larynx, that extended to the tracheobronchial tree, and deep ulcers in the membranous wall of the trachea. The histopathology examination revealed an inflammatory process that was diagnosed secondary to the vasculitis, but no infections. Superior and inferior airway lesions in the same patient with dermatomyositis is a very rare condition. The association of dermatomyositis with deep mucosal ulcers and pneumomediastinum is not clear, but a bronchoscopic examination should be used to improve evaluation.

El traumatismo torácico es un problema emergente de las grandes ciudades al aumentar los accidentes de tránsito. Se ha reportado neumomediastino hasta en 10 por ciento de los pacientes con contusión torácica, debiéndose este a lesiones traqueobronquiales en menos de 2 por ciento de los casos. A pesar de que la causa de enfisema mediastinal se desconoce en la mayoría de los pacientes, en muchos de ellos su etiología se puede deber al efecto Macklin. Esta presentación de caso trata sobre un paciente masculino de 40 años de edad con el antecedente de trauma complejo, presentando enfisema subcutáneo que afecta la cara anterior del tórax hasta los rebordes costales. En los estudios radiológicos se evidenció neumomediastino. Aunque la presencia del efecto Macklin representa un reto diagnóstico, una vez que este se ha establecido, el manejo debe basarse en el tratamiento de las lesiones asociadas. La presencia del efecto Macklin refleja el grado de severidad de la contusión torácica, por lo que estos pacientes deben ser monitorizados y manejados en el ambiente de la Unidad de Cuidados Intensivos. El objetivo de este trabajo fue reportar un caso de neumomediastino secundario a efecto Macklin, en un paciente con trauma cerrado de tórax, y revisar la fisiopatología de este mecanismo de fuga aérea.
The thoracic traumatism is an emergent problem from the big cities when increasing the traffic accidents. The pneumomediastinum it has been reported until 10 percent in patient with thoracic bruise, being due to Tracheobronchial lesions in less than 2 per cent of the cases. Although the cause of mediastinal emphysema is ignored in most of the patients, in many of them its etiologic could be by Macklin effect. This case tries on a 40 year-old masculine patient with the antecedent of complex trauma, presenting subcutaneous emphysema that affects the anterior part of the thorax until the ribs. In the radiological studies Neumomediastino is evidenced. Although the presence of the effect Macklin represents a challenge diagnosis, once this has settled down the handling it should be based on the treatment of the associate lesions. The presence of the Macklin effect show the degree of severity of the thoracic bruise, for these reason those patientes should be admited in ICU. The objective of this publication is to report a case of pneumomediastinum secundary to Macklin effect in a patient with closed trauma of thorax and take in considerations the fisiopatologic of this mechanism of air leak.

Large post intubation tracheal tears are usually detected intra-operatively due to unstable signs namely impaired ventilation and mediastinal emphysema and often require surgical management. Smaller tracheal tears are often missed during anaesthesia and recognized during the postoperative period. Conservative management should be considered in these latter cases.
Grandes desgarros traqueales tras una entubación se detectan usualmente intra-operativamente debido a señales inestables, a saber, ventilación defectuosa y enfisema del mediastino. Tales desgarros requieren a menudo tratamiento quirúrgico. Los desgarros traqueales menores no se ven a menudo durante la anestesia y se reconocen sólo durante el periodo postoperatorio. Un tratamiento conservador debe ser objeto de consideración en estos últimos casos.

The spontaneous pneumomediastinum is the presence of air inside the mediastinum without a traumatic or iatrogenic reason associated. It is a slightly frequent entity and as the spontaneous pneumotorax it is given especially in young males. In rare occasions it associates to an episode of vomits and in this case it is necessary to make a differential diagnosis with Boerhaave's syndrome because at the first moment the clinic can be similar in both cases. Nevertheless, while the spontaneous pneumomediastinum is quite often to be a benign entity with good prediction, Boerhaave's syndrome has a mortality of 80 percent-90 percent if the diagnosis is produced after 24-48 hours.
El neumomediastino espontáneo es la presencia de aire dentro del mediastino sin que exista una causa traumática o iatrogénica asociada. Es una entidad poco frecuente que, al igual que el neumotorax espontáneo, se da sobre todo en varones jóvenes. En raras ocasiones se asocia a un episodio de vómitos y, en este caso, es necesario hacer un diagnóstico diferencial con el síndrome de Boerhaave ya que en un primer momento la clínica puede ser similar en ambos cuadros. Sin embargo, el neumomediastino espontáneo suele ser una entidad benigna con buen pronóstico y el síndrome de Boerhaave es un cuadro de mal pronóstico y que, de diagnosticarse después de 24-48 horas, puede tener hasta un 80 por ciento-90 por ciento de mortalidad.

Várias complicações podem estar relacionadas a procedimentos cirúrgicos na área de cabeça e pescoço. O pneumomediastino, pneumotórax e enfisema subcutâneo estão descritos em menor número de casos, em relação às demais complicações. Nesses procedimentos, constata-se importante o cuidado com a técnica cirúrgica, evitando manobras cirúrgicas agressivas, além de parcimônia no uso de máscaras de oxigênio sob pressão positiva e intubação. Este estudo relata um caso de enfisema subcutâneo, pneumotórax e pneumomediastino, com aparecimento 48 horas após tonsilectomia palatina, e discute possíveis mecanismos, morbidade, formas de prevenção e tratamento
Several complications can be related to surgical approaches of the head and neckareas. Subcutaneous emphysema, pneumothorax and pneumomediastinum are described in a small number of cases, among others. In these surgeries, a careful surgical technique approach is of utmost importance, and aggressive surgical maneuvers should be avoided.Caution should be taken with the use of oxygen masks for positive pressure ventilation during anesthesia recovery and intubation. This study reports a case of pneumomediastinum, pneumothorax and subcutaneous emphysema that appeared 48 hours after palate tonsillectomy and discusses possible mechanisms, morbidity, ways of prevention and treatment
