This case report presents an iatrogenic induced mediastinal emphysema after restorative treatment of the lower left second molar, aimed to highlight the potential life-threatening consequences, and providing diagnostics and treatment concepts of complicated dental induced emphysema based on literature review. A 74-year-old female patient was admitted to the emergency department due to a fall on her shoulder. Additional finding was a significant swelling of the face and neck. In the computer tomography of the head, neck, and thorax, a humerus fracture and pronounced soft tissue emphysema from the infraorbital region to the mediastinum was detected. The patient reported that she had been treated by her dentist 4 days earlier. The treatment had to be discontinued after beginning of a pronounced swelling. Other reasons for the emphysema could be excluded out on an interdisciplinary teamwork. The patient was monitored as an inpatient for 5 days and received intravenous antibiotic therapy. This case report shows the rare complication of pronounced mediastinal emphysema after root canal treatment. Emphysema should always be a differential diagnosis of soft tissue swelling and, in case of doubt, a general medical presentation should be made.

INTRODUCTION
Coronavirus disease 2019 (COVID-19) can cause multisystem complications, with pulmonary involvement associated with the highest mortality. Pneumothorax (PT) and pneumomediastinum (PM) are uncommon complications of COVID-19 that have been reported to occur in the absence of trauma or mechanical ventilation. This study seeks to determine the incidence of these complications in patients with COVID-19 and evaluate clinical characteristics and outcomes.
METHODS
We identified 3375 patients admitted to our health system during March 2020 through November 2020 who tested positive for SARS-CoV-2 with a polymerase chain reaction test. Patients were screened for PT or PM and were matched to COVID-19-positive patients without PT and/or PM. Data compared demographics, clinical characteristics, and laboratory values.
RESULTS
Out of a total of 3375 COVID-19 admissions, 33 patients with PT/PM (1%) were compared to 32 matched controls without PT and/or PM. The patients with PT and/or PM demonstrated a significantly higher incidence of concomitant cancer diagnosis than those without PT and/or PM (18% vs 3%, respectively; = 0.05). Those with PT and/or PM required significantly more invasive mechanical ventilation than those without PT and/or PM (79% vs 47%; < 0.01). Mortality was significantly higher among those patients with PT and/or PM than those without PT/PM (55% vs 25%; < 0.05).
DISCUSSION
A significant number of COVID-19 patients with PT and/or PM had a concomitant cancer diagnosis, required supplemental oxygen on admission, and invasive mechanical ventilation during hospitalization. Additionally, the COVID patients with PT and/or PM had significantly higher mortality compared to those without PT and/or PM. However, with all retrospective studies, there are limitations.

INTRODUCTION
Tonsillectomy is known as one of the safest otorhinolaryngology surgery procedure. Rarely, it can lead to serious complications. Cervico-facial emphysema is an exceptional complication of tonsillectomy. Here we reported a case of post-tonsillectomy emphysema. Our objective was to emphasize the different characteristics of this entity and draw attention to the risk of potentially fatal respiratory complications.
PRESENTATION OF CASE
A 46-year-old healthy woman had a tonsillectomy because of recurrent tonsillitis. Four hours after extubation, she presented a subcutaneous emphysema under the left mandibular angle, slightly extended to the left cheek and left laterocervical region. An immediate cervicofacial CT scan showed a dissecting cervical emphysema of the left hemiface of moderate abundance that extended to the pre-vascular space of the superior mediastinum. The decision was to keep the patient hospitalized, to avoid forced glottic closure and to put her on prophylactic antibiotics. The further course was uneventful with respiratory state stability and emphysema's disappearance.
CLINICAL DISCUSSION
Cervicofacial emphysema is a very rare but life-threatening tonsillectomy complication that may cause acute respiratory failure. Emphysema's main clinical characteristics are a non-tender cervicofacial swelling and crepitus. Post-tonsillectomy emphysema treatment is usually conservative. In cases of respiratory failure, it is necessary to secure the airway by intubation or tracheostomy. An important mediastinal expansion of the emphysema requires a thoracotomy.
CONCLUSION
Cervicofacial emphysema is an unpredictable complication of tonsillectomy. Its prevention requires per-operative vigilance from both ENT surgeons and anesthetists. Moreover, early diagnosis and management are essential to avoid its potentially fatal consequences.

Subcutaneous emphysema (SE) and pneumomediastinum are rare complications of air beneath the skin layers and in the mediastinal space, respectively, following routine dental procedures. A few cases exist in the literature. A 53-year-old female presented to the emergency department shortly after a cavity filling, with marked swelling of her right orbit, face, and neck. Physical examination and computed tomography (CT) revealed subcutaneous emphysema and pneumomediastinum. The patient was treated with prophylactic antibiotics for one week and Peridex rinse twice daily. Subcutaneous emphysema and pneumomediastinum cases have been associated with potentially life-threatening sequelae and infections. Although these conditions are almost exclusively benign and self-limiting, physicians should consider the associated fatal complications and manage accordingly. Dental providers should be able to recognize this complication and provide patients with appropriate guidance.

OBJECTIVES
Uniportal incision located at 4th or 5th intercostal space represents a problem for the correct drainage of distal areas of pleural cavity. The T-shaped tube can drain both the extremities of pleural space. In this study, we evaluated the effectiveness of T-chest tube compared to classic chest tube after uniportal video-assisted thoracic surgery.
METHODS
We compared the effectiveness of T-tube and classic 28 CH chest drainage after different surgical procedures in uniportal video-assisted thoracic surgery: lobectomies, wedge resections and pleural and mediastinal biopsies. As primary end points, drained effusion and evidence of pneumothorax at postoperative day 1, subcutaneous emphysema, tube kinking, obstruction and necessity of repositioning or postoperative thoracentesis were considered. Pain at 6 and 24 h after surgery, pain at tube removal and mean hospitalization were analysed as secondary end points.
RESULTS
A total of 109 patients were selected for the study, 51 included to the T-tube group while the other 58 ones to the control group with classic drainage. Patients with T-tube showed a significantly lower rate of pneumothorax (29.4% vs 63.8%; P < 0.001), tube kinking (5.9% vs 27.6%; P = 0.003) and need of repositioning (2.0% vs 12.1%; P = 0.043). No significant results were obtained in subcutaneous emphysema (P = 0.26), tube obstruction (P = 0.32), drained effusion (P = 0.11) and need of postoperative thoracentesis (P = 0.18). Patients with T-tube complained of <6 h after surgery (P < 0.001). Conversely, T-tube removal was reported to be more painful (P < 0.001).
CONCLUSIONS
Chest T-tube can achieve significantly lower rate of postoperative pneumothorax, kinking and repositioning with less pain 6 hours after surgery compared to classic tube.

BACKGROUND Spontaneous pneumomediastinum and subcutaneous emphysema (Hamman's syndrome) presents with sudden and life-threatening symptoms. Clinical signs include crackles that synchronize with the heartbeat on chest auscultation (Hamman's sign). This report describes the case of a 29-year-old woman with a protracted second stage of labor at 40 weeks of pregnancy with postpartum dyspnea, acute chest pain, and surgical emphysema due to pneumomediastinum (Hamman's syndrome). CASE REPORT This case report describes the case of a 29-year-old primigravida admitted to the hospital ward for spontaneous labor at 40 weeks of pregnancy. Due to a protracted second stage of labor, the delivery was assisted by Thierry's spatulas. Shortly after delivery, the patient developed dyspnea associated with subcutaneous emphysema in the inferior part of the face, neck, and anterior chest wall. As the clinical evaluation showed no signs of severity, we performed a chest X-ray, which confirmed the diagnosis of pneumomediastinum (Hamman's syndrome), excluded any other life-threatening condition, and led to a conservative treatment approach. CONCLUSIONS This report presents a rare association between protracted labor and Hamman's syndrome and highlights the importance of rapid diagnosis and management. In this case, the postpartum presentation was distinguished from pulmonary embolism, and emergency life-saving management was initiated.

OBJECTIVE
Pleural adhesions (PLAs) have been shown to be a possible risk factor for air leak after lung volume reduction surgery (LVRS), but the relevance of PLA for lung function outcome remains unclear. We analyzed our LVRS cohort for the influence of PLA on short-term (ie, prolonged air leak) and long-term outcomes.
METHODS
Retrospective observational cohort study with 187 consecutive patients who underwent LVRS from January 2016 to December 2019. PLA were defined as relevant if they were distributed extensively at the dorsal pleura; were present in at least at 2 areas, including the dorsal pleura; or present extensively at the mediastinal pleura. In patients with bilateral emphysema, bilateral LVRS was performed preferentially. The objectives were to quantify the association of PLA and rate of prolonged air leak (chest tube >7 days), and the association of PLA with postoperative exacerbations and with forced expiratory volume in 1 second 3 months postoperatively. The associations were quantified with odds ratios for binary outcomes, and with between-group differences for continuous outcomes. To account for missing observations, 100-fold multiple imputation was used.
RESULTS
PLAs were found in 46 of 187 patients (24.6%). There was a 32.6% rate of prolonged air leak (n = 61), mean chest tube time was 7.84 days. A total of 94 (50.3%) LVRSs were unilateral and 93 were bilateral. There was evidence for an association between PLA and the rate of prolonged air leak (odds ratio, 2.83; 95% CI, 1.36 to 5.89; = .006). There was no evidence for an association between PLA and postoperative exacerbations (odds ratio, 1.11; 95% CI, 0.5 to 2.45; = .79). There was no evidence for an association between PLA and forced expiratory volume in 1 second (estimate -1.52; 95% CI -5.67 to 2.63; = .47). Both unilateral and bilateral LVRS showed significant postoperative improvements in forced expiratory volume in 1 second by 27% (8.43 units; 95% CI, 3.66-13.12; = .0006) and by 28% (7.87 units; 95% CI, 4.68-11.06; < .0001) and a reduction in residual volume of 15% (-33.9 units; 95% CI, -56.37 to -11.42; = .003) and 15% (-34.9 units; 95% CI, -52.57 to -17.22; = .0001), respectively.
CONCLUSIONS
Patients should be aware of potential prolongation of hospitalization due to PLA. However, there might be no relevant influence of PLA on lung function outcomes.

Spontaneous pneumomediastinum is a rare medical condition characterized by the presence of free air in the mediastinum, not preceded by trauma, surgery, or another medical procedure. It predominantly affects young adult males and usually has a benign course, and in most cases, it is not possible to identify the precipitating factor. There are some conditions that predispose to its occurrence, namely those that lead to an increase in intrapleural pressure, such as coughing, vomiting, or vigorous exercise. We report a case of a 21-year-old male who presented with acute-onset shortness of breath after an episode of coughing and was found to have mediastinal and subcutaneous emphysema. Clinical, laboratory, and radiological studies did not demonstrate any predisposing factor, and the case was classified as spontaneous pneumomediastinum.

BACKGROUND
Mediastinal emphysema is a condition in which air enters the mediastinum between the connective tissue spaces within the pleura for a variety of reasons. It can be spontaneous or secondary to chest trauma, esophageal perforation, medically induced factors, Its common symptoms are chest pain, tightness in the chest, and respiratory distress. Most mediastinal emphysema patients have mild symptoms, but severe mediastinal emphysema can cause respiratory and circulatory failure, resulting in serious consequences.
CASE SUMMARY
A 75-year-old man, living alone, presented with sudden onset of severe epigastric pain with chest tightness after drinking alcohol. Due to the remoteness of his residence and lack of neighbors, the patient was found by his nephew and brought to the hospital the next morning after the disease onset. Computed tomography (CT) showed free gas in the abdominal cavity, mediastinal emphysema, and subcutaneous pneumothorax. Upper gastrointestinal angiography showed that the esophageal mucosa was intact and the gastric antrum was perforated. Therefore, we chose to perform open gastric perforation repair on the patient under thoracic epidural anesthesia combined with intravenous anesthesia. An operative incision of the muscle layer of the patient's abdominal wall was made, and a large amount of subperitoneal gas was revealed. And a continued incision of the peritoneum revealed the presence of a perforation of approximately 0.5 cm in the gastric antrum, which we repaired after pathological examination. Postoperatively, the patient received high-flow oxygen and cough exercises. Chest CT was performed on the first and sixth postoperative days, and the mediastinal and subcutaneous gas was gradually reduced.
CONCLUSION
After gastric perforation, a large amount of free gas in the abdominal cavity can reach the mediastinum through the loose connective tissue at the esophageal hiatus of the diaphragm, and upper gastrointestinal angiography can clarify the site of perforation. In patients with mediastinal emphysema, open surgery avoids the elevation of the diaphragm caused by pneumoperitoneum compared to laparoscopic surgery and avoids increasing the mediastinal pressure. In addition, thoracic epidural anesthesia combined with intravenous anesthesia also avoids pressure on the mediastinum from mechanical ventilation.
