ABSTRACT
Introducción: el síndrome de Hamman es la aparición de neumomediastino espontáneo asociado a enfisema, patología poco frecuente en pediatría. Sus síntomas principales son dolor torácico agudo, disnea y enfisema subcutáneo. Objetivo: describir una experiencia clínica en la que se sospechó este síndrome analizando el proceso diagnóstico, estudios complementarios y el tratamiento. Caso clínico: varón de 4 años, con antecedentes personales de laringitis a repetición. Presenta laringitis aguda severa, requirió ventilación no invasiva por 12 horas. A las 24 horas del ingreso instaló de forma brusca estridor inspiratorio, dificultad respiratoria, edema de cuello y cara con crepitación a nivel de cuello y cara anterior del tórax que se fue extendiendo a ambos brazos. Se realiza radiografía de tórax que evidencia enfisema subcutáneo extenso. Se realiza tomografía de cuello y tórax que descarta lesión en vía aérea. Con el planteo de síndrome de Hamman en un niño que presentaba como factor predisponente el episodio de laringitis aguda, se decidió no continuar con estudios complementarios. Se realizó tratamiento fisiopatológico con buena evolución clínica. Alta a la semana del ingreso. Conclusiones: el diagnóstico en la urgencia del neumomediastino espontáneo puede representar un desafío, con una variedad de diagnósticos diferenciales potencialmente mortales. La alta sospecha permitirá realizar una evaluación clínica e imagenológica adecuada que permitan confirmar su diagnóstico y evitar procedimientos invasivos innecesarios.
Introduction: Hamman's syndrome involves the appearance of spontaneous pneumomediastinum associated with emphysema, a rare pathology in pediatrics. Its main symptoms include acute chest pain, dyspnea and subcutaneous emphysema. Objective: to describe a clinical case of this suspected syndrome by analyzing the diagnostic process, supplementary studies, and treatment. Clinical case: 4-year-old male with personal history of repeated laryngitis. He presented severe acute laryngitis, requiring non-invasive ventilation for 12 hours. Twenty-four hours after admission he developed abrupt inspiratory stridency, respiratory distress, neck, and face edema with crepitation at neck level and front of thorax spreading to both arms. A chest X-ray shows extensive subcutaneous emphysema. A neck and chest CT scan rules out airway injury. With the suggestion of Hamman's syndrome in a child who presented acute laryngitis as a predisposing factor the episode, it was decided not to continue with additional studies. Physio-pathological treatment was carried out with good clinical evolution. He was discharged a week after admission. Conclusions: diagnosis of spontaneous pneumomediastinum can be challenging in an emergency setting and having a variety of potentially life-threatening differential diagnoses. High suspicion levels will enable an adequate clinical and imaging assessment to confirm its diagnosis and avoid unnecessary invasive procedures.
Introdução: síndrome de Hammam é o aparecimento de pneumomediastino espontâneo associado ao enfisema, uma patologia rara na pediatria. Seus principais sintomas são dor aguda no peito, dispneia e enfisema subcutâneo. Objetivo: descrever um caso clínico com suspeita dessa síndrome por meio da análise do processo diagnóstico, estudos complementares e tratamento. Caso clínico: menino de 4 anos com histórico pessoal de laringite recorrente. Teve laringite aguda grave, o que exigiu ventilação não invasiva por 12 horas. Dentro de 24 horas após a internação, instalou-se abruptamente estridor inspirador, dificuldade respiratória, edema do pescoço e rosto com estalos ao nível do pescoço e face anterior do peito, estendido para ambos braços. Raios-x do tórax mostram enfisema subcutâneo extenso. Tomografia do pescoço e tórax exclui lesões nas vias aéreas. Com a sugestão da síndrome de Hammam em uma criança que apresentou como fator predisponente o episódio de laringite aguda, decidiu-se não continuar com estudos complementares. O tratamento fisiopatológico mostrou boa evolução clínica. A alta teve lugar dentro de uma semana da data da internação. Conclusões: o diagnóstico na urgência do pneumomediastino espontâneo pode representar um desafio, além do mais quando existem uma variedade de diagnósticos diferenciais que ameaçam a vida. A alta suspeita permitirá uma avaliação clínica e de imagem adequada para confirmar o diagnóstico e evitar procedimentos invasivos desnecessários.

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

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.

A síndrome de Hamman foi descrita pela primeira vez por Louis Hamman, em 1939, como "enfisema mediastinal espontâneo" e corresponde à presença de ar livre no mediastino, sem relação com trauma e/ou procedimentos invasivos na região torácica. A condição apresenta sintomas inespecíficos como dor torácica, dispneia, tosse, disfonia, disfagia e dor cervical. Devido aos sinais e sintomas inespecíficos, essa condição pode ser subdiagnosticada, contribuindo para a sua baixa incidência. O diagnóstico é estabelecido com exames de imagem como radiografia e tomografia computadorizada de tórax. No relato de caso descrito, temos uma paciente de 31 anos, gestante, G2P1A0, que desenvolve a síndrome concomitantemente a episódios de hiperêmese gravídica com cinco semanas e cinco dias de idade gestacional. O objetivo deste relato concentra-se em destacar essa hipótese diagnóstica para assistência adequada à paciente, uma vez que tal condição não faz parte do escopo cotidiano dentro da obstetrícia.(AU)
Hamman's syndrome was first described by Louis Hamman in 1939 as "spontaneous mediastinal emphysema" and is characterized by the presence of air in the mediastinum, unrelated to trauma, and/or invasive procedures in the thoracic region. The condition presents nonspecific symptoms such as thoracic pain, cervical pain, dyspnea, cough, and dysphonia. Due to the nonspecific signs and symptoms, this condition can be misdiagnosed, contributing to its low incidence. A diagnosis is established through imaging examinations such as chest radiography and computerized tomography. Here, we report the case of a 31-year-old female who developed Hamman's syndrome concomitantly with episodes of severe hyperemesis when she was five weeks and five days pregnant. Hamman's syndrome is a rare presentation in the field of obstetrics. This report seeks to highlight how Hamman's syndrome was diagnosed, discuss the care given to the patient, and explain the correlation between hyperemesis gravidarum and Hamman's syndrome.(AU)

La ingestión de nitrógeno líquido es una causa infrecuente de perforación gástrica, se conoce poco sobre como este compuesto afecta el tejido gastrointestinal, sus mecanismos de lesión y sus consecuencias clínicas. Cada vez es más frecuente el uso del nitrógeno líquido de forma comercial en productos de repostería y gastronomía, por lo que es importante reconocer sus potenciales efectos cuando la manipulación no es la adecuada. En este caso clínico describimos una perforación gástrica secundaria al consumo de helado preparado con nitrógeno líquido.
Liquid nitrogene ingestion is a frecuent cause of gastric perforation. It is unknown how this compound afects the gatrointestinal tissue, it mechanisisms of injury and the clinical consecuences. Nowadays, the use of liquid nitrogene in gastronomy is becoming a tendency, for this reason it is important to identify the potencial healt effects of this compound when is not correctly manipulated. The following article describes a secondary gastric perforation, as a consecuence of the consumption of ice cream prepared with liquid nitrogene.

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.

A 50-year-old male, a tobacco smoker, who was known to have ulcerative colitis presented with dry cough, chest pain, dysponea and frequent passage of blood and mucous mixed stools. Physical examination revealed clubbing, subcutaneous emphysema of upper chest and auscultatory findings of crunching sound over pre-cordial area and basal crepitations. Spirometry was suggestive of restrictive pattern. High resolution computed tomography (HRCT) of thorax revealed pneumomediastinum, subcutaneous emphysema, bilateral diffuse centrilobular nodules and ground-glass haziness with mosaic pattern along with posterior basal fibrotic changes. The present case documents the uncommon pulmonary involvement of spontaneous pneumomediastinum and subcutaneous emphysema diffuse parenchymal lung disease, in a patient with ulcerative colitis.
