Project description:Hamman's syndrome is a rare clinical entity that presents with spontaneous pneumomediastinum and subcutaneous emphysema. It is most commonly diagnosed in young men and pregnant women, and is rare in children. We report the case of a female toddler who presented to an emergency department with fever, cough and shortness of breath. Imaging studies revealed subcutaneous emphysema and pneumomediastinum. The patient was diagnosed with Hamman's syndrome after ruling out other possibilities. We discuss the underlying mechanisms of the disease, the diagnostic criteria and the treatment options. The purpose of this case report is to improve clinicians' awareness of the existence of this rare clinical entity in paediatric patients.

Project description:AimPneumothorax (PNX), pneumomediastinum (PMD) and subcutaneous emphysema (SCE) are COVID-19 complications related to positive-pressure ventilation. We analyzed the pathophysiology of these complications without ventilation.Patients & methodsOut of 1845 admitted COVID-19 patients, we retrospectively collected data for 15 patients, from a tertiary medical center, from 1 October 2020 to 31 March 2021.ResultsFive patients suffered from spontaneous PNX, 8/15 developed PMD and 8/15 developed SCE. The mean BMI was 29.7, as most patients were obese or overweight. Most patients had lymphocytopenia and increased C-reactive protein, ferritin and lactate dehydrogenase levels. Eleven patients succumbed to the disease.ConclusionRisk factors of spontaneous PNX, PMD and SCE in COVID-19 patients need further investigations by conducting more comprehensive case-control studies.

Project description:The terms "free air or gas located within the mediastinum and subcutaneous tissue that are not associated with any obvious causes, such as chest trauma," are used to characterise spontaneous pneumomediastinum (SPM) and subcutaneous emphysema (SE). SPM has been linked to a variety of illnesses and causes, including bronchial asthma, diabetic ketoacidosis, strenuous exercise, strenuous coughing, medication intake, and other actions involving the Valsalva maneuver. We describe a case of spontaneous cervical, retropharyngeal, and mediastinal emphysema in a young female who was previously healthy. She was brought into the ward for observation, vital sign monitoring, analgesics, and prophylactic antibiotics. She started taking analgesics, preventative antibiotics, and 100% oxygen throughout that period to help with absorption. The neck pain gradually subsided, and there were no bouts of oxygen desaturation or abnormal vital signs. After subsequently getting better, the patient went home. The patient was examined in an outpatient clinic two weeks after being discharged and shown no signs of illness. To sum up, subcutaneous emphysema and pneumomediastinum are uncommon presentations seen in the emergency room, but they are typically self-limiting.

Project description:In maxillofacial surgery, tracheostomy is indicated in congenital, inflammatory, oncologic, or traumatic respiratory obstruction. In traumatic cases, however, it is sometimes hard to implement. We describe subcutaneous emphysema following emergent surgical conventional tracheostomy performed after stab injury to the floor of the mouth. We analyze the course that led to this complication and discuss suggestions on how to avoid it. In addition, we review the literature to improve our knowledge and practice regarding this entity. Massive subcutaneous neck emphysema occurred because ventilation started at the time when the hemorrhage was not completely managed and the tracheal tube was not fully secured. In traumatic cases with profound bleeding, hemorrhage management must be performed carefully. The recommendation not to ventilate until the hemorrhage is completely managed should be observed.

Project description:We present a case of a 28-year-old primiparous woman with facial swelling followed by acute chest pain immediately after delivery. Chest radiograph revealed pneumomediastinum and surgical emphysema. She recovered well within 24 h of observation and conservative management. Postpartum spontaneous pneumomediastinum should be considered in the differential diagnosis of sudden-onset postpartum chest pain immediately or a few hours after delivery. It is a rare benign condition and usually resolves spontaneously without serious consequences. Chest X-ray is the single most important diagnostic test. It is important to rule out other serious and life-threatening conditions. Prolonged pushing, difficult labour and use of inhalational drugs place young primiparous women at higher risk. Recurrence is uncommon in subsequent pregnancy and management is unclear, although expectant management with epidural analgaesia to prevent recurrence in subsequent pregnancy is suggested.

Project description:Cervicofacial subcutaneous emphysema (SE) is primarily caused by dental treatment introducing gas into the subcutaneous tissue. Air rapidly dissects into the subcutaneous tissue with face and neck swelling, leading to respiratory distress, patient discomfort, and chest pain. Computed tomography (CT) can detect spreading SE patterns. However, the true volume of SE and the degree of air changes in the body over time remain unknown. We evaluated the healing process of SE and the temporal changes in the volume of emphysema in three cases detected using our hospital's electronic health record systems based on inclusion and exclusion criteria over the past 10 years, with CT and three-dimensional (3D) images. The first case was a 46-year-old woman who presented with complaints of swelling from her right eyelid to the neck and clavicles, pain on swallowing, respiratory distress, and hoarseness. The second case was a 35-year-old man who presented with complaints of swelling over the face. The third case was a 36-year-old man who presented with complaints of swelling from the left cheek to the neck. CT revealed SE and pneumomediastinum in all cases. All the patients were administered an antibacterial drug. The CT and 3D images showed an improvement in emphysema 3 days after the onset, with more than half of the volume reduction in emphysema. This made it possible to evaluate the changes in the air content of SE. Observation with CT until the healing process of SE is completed is crucial, and 3D images also help evaluate changes over time.

Project description:Subcutaneous emphysema occurs when air is forced under the tissue, causing swelling, crepitus on palpation, and the possibility of spreading along the fascial planes. Although subcutaneous emphysema secondary to dental procedures is rare, it can be a potentially fatal complication if not diagnosed and treated promptly and correctly. Dentists need to be able to differentiate subcutaneous emphysemas from more common disease processes that have similar clinical presentations. We report a 22-year-old male who underwent mandibular wisdom tooth extraction and subsequently developed extensive subcutaneous emphysema. The patient was quickly taken care of, in partnership with the maxillofacial department. The purpose of this report is to bring attention to the fact that obtaining an accurate diagnosis for this condition is very important and management on time can prevent serious complications.

Project description:IntroductionMycobacterium abscessus is a rapidly growing mycobacterium commonly identified in adults with underlying pulmonary diseases but is rarely observed in children. A better understanding of this pathogen in children is essential.Case presentationWe report the case of a 49-month-old female child without previous underlying pulmonary diseases but with acute lymphoblastic leukemia (ALL). The patient was complicated with pneumonia during chemotherapy, which was primarily characterized by spontaneous pneumomediastinum and subcutaneous emphysema on chest computed tomography (CT). M. abscessus sequences were detected by metagenomic next-generation sequencing in bronchoalveolar lavage fluid. With mechanical ventilation, closed thoracic drainage, and anti-infective therapy for 6 months, the patient's infection was controlled. The patient completed 2.5 years of treatment for ALL, and the drugs were discontinued. The patient currently remains in complete hematologic remission.DiscussionWe reviewed the literature on 33 children with M. abscessus pulmonary disease. These children mostly had underlying immunodeficiency. Chest CT most often showed nodular shadows, consolidation, and bronchiectasis. Spontaneous pneumomediastinum and subcutaneous emphysema were not reported as major manifestations.ConclusionSpontaneous pneumomediastinum and subcutaneous emphysema were our patient's main characteristics on chest CT, and this study enriches the knowledge regarding possible imaging changes in M. abscessus pulmonary disease in children. This case report reflects good clinical experience in maintaining the balance between chemotherapy and anti-infective therapy in childhood ALL.

Project description:BackgroundSubcutaneous emphysema and mediastinal emphysema and/or pneumothorax after mechanical ventilation through endotracheal intubation is not uncommon. However, cases of delayed mediastinal emphysema and subcutaneous emphysema after extubation and their further development into pneumothorax have rarely been reported, especially in children. Given this, we provide such a case for the reference of clinicians.Case descriptionWe report a case of a 2-year-old girl with no abnormalities at the preoperative examination, who developed subcutaneous emphysema and mediastinal emphysema 4 hours after recovery from general anesthesia due to ophthalmic arterial infusion chemotherapy for retinoblastoma, and bilateral pneumothorax 12 hours later. The patient recovered and was discharged following aggressive treatment of subcutaneous exhaust and thoracic closed drainage. Due to fiberoptic bronchoscopy was refused by the guardian to determine the cause, we hypothesized tracheal intubation injury occurs, air enter the trachea or bronchial mucosa, extend up to the neck, head and face along the blood vessels, larynx and deep cervical fascia spaces, causing subcutaneous emphysema, and then gradually spread to the mediastinum, resulting in mediastinal emphysema and pneumothorax. However, the etiology and preventive measures warrant further study.ConclusionsStrengthen the etiological study of subcutaneous and/or mediastinal emphysema and pneumothorax due to endotracheal intubation, perioperative observation and postoperative follow-up are important measures for the effective prevention, early diagnosis, and timely treatment of subcutaneous and/or mediastinal emphysema and pneumothorax, and are also conducive to ensuring the safety of patients.
