Spontaneous cervical and mediastinal emphysema.

Subcutaneous cervical emphysema often appears as a result of surgery or trauma. However, when it occurs spontaneously, the patient may present with clinically impressive and dramatic features. The etiology is related to the rupture of terminal alveoli and dissection of air along the pulmonary vasculature. Exercise may contribute to the process by increases in intrathoracic pressure. Six cases of spontaneous cervical emphysema, all related to SCUBA diving training at a Naval facility, were recently seen at our institution. Proper management entails having a high index of suspicion for diagnosis, and then being able to identify potentially life-threatening complications.

OBSERVATIONS ON THE CLASSIFICATION AND DISTRIBUTION OF PULMONARY EMPHYSEMA IN CANADA.

General principles of epidemiology are reviewed, using as an example the chronic non-specific respiratory diseases in Canada. Lack of agreement in definition and classification seriously hampers the use of governmental statistics to study the epidemiology of these diseases. Though Canada is experiencing a mid-century epidemic of deaths from emphysema, evidence is presented which suggests that provincial variation in this death rate is artificial and is likely apparent because physicians do not categorize deaths from this and related diseases in any similar fashion. Three-year-average age-standardized death rates by provincial areas for emphysema with or without bronchitis, asthma, chronic bronchitis and bronchiectasis are presented in evidence that provincial variation is largely obliterated when all chronic non-specific respiratory diseases are considered as a single nosological unit. Advantages and disadvantages of a recent clinical classification of these diseases are reviewed, and it is concluded that such a classification has a great deal to offer epidemiologists or clinicians studying the cause and natural history of these diseases.

BRONCHIOLAR EMPHYSEMA. A REPORT OF A NECROPSIED CASE OF DIFFUSE BRONCHIOLECTASIS AND REVIEW OF THE LITERATURE.

Bronchiolar emphysema is a rare, insidious, progressive, bilateral pulmonary fibrosis with diffusion defect. Death follows in five to 10 years after the onset of symptoms because of respiratory failure, cor pulmonale or pneumothorax. In the 20 cases reviewed, the lungs typically showed bosselation of their pleural surfaces, giving the appearance and consistency of a liver involved by Laennec's cirrhosis. Cross sections showed honeycombing chiefly along the lung margins. Microscopically, cystic dilatation of terminal bronchioles was present, with obliteration of the remaining peripheral lung tissue by a dense pulmonary fibrosis. Hyperplasia of smooth muscle and elastica was prominent.Bronchiolar emphysema is a clinicopathologic entity, the etiology of which is unknown and likely multiple. Bronchiolectasis and superimposed recurrent infection are essential in its pathogenesis. Thickening of alveolar walls may play a decisive role in determining the characteristic site of the bronchiolar dilatation.

[Epidural, mediastinal and subcutaneous emphysema in a patient with suspected torme fruste of Marfan syndrome].

A 17 year-old youth presented with swelling of both sides of neck after a fight with a friend. He had been sick with an upper respiratory tract infection for a few days with frequent coughing. Chest radiography showed subcutaneous and mediastinal emphysema. Neck CT at the level of C7 showed air around the trachea, extending to the subcutaneous tissue and the epidural space through the intervertebral foramen. His height was 180 cm and his weight 55 kg, and he had a 181 cm arm span. He had scoliosis and arachnodactyly, and ultrasonic cardiography demonstrated mitral and tricuspid regurgitation. These findings agreed partially with the clinical criteria of Marfan syndrome. Thus, forme fruste of Marfan syndrome was suspected. A rapid rise of airway pressure induced by a coughing attack and loud shouting during the fight probably caused the laceration of the connective tissue in the airway, resulting in mediastinal and epidural emphysema. In this case report, CT at the C7 level satisfactorily identified air in the mediastinum extending to the epidural space through intervertebral foramen.

[A case of spontaneous epidural emphysema occurring during sleep].

A 19-year-old man consulted a doctor for swelling of his neck and shortness of breath. The day before, he woke up with a slight cough and upper chest pain early in the morning. He went to school and spent the day as usual. He did not have a history of asthma or violent cough. The next day, chest radiography showed subcutaneous emphysema and pneumomediastinum. Computed tomography not only confirmed the presence of mediastinal and subcutaneous air, but also demonstrated a linear radiolucent stripe in the spinal canal corresponding to epidural emphysema. The patient did not have any neurologic findings. His general condition remained good except that his arterial blood oxygen saturation slightly decreased to 95%. Laboratory data were normal, except for serum IgE, which was elevated (2072 IU/ml). He stayed at rest and was treated conservatively and his symptoms improved within a few days. Seven days later, the intraspinal air and pneumomediastinum had resolved spontaneously on follow-up chest computed tomography (CT).

The relationship between selenium deficiency and the development of pulmonary and subcutaneous emphysema in bovine ephemeral fever virus-infected cattle.

Bovine ephemeral fever (BEF) was diagnosed on several commercial farms around Harare, Zimbabwe. The affected animals showed signs of fever (40-41.5 degrees C), depression, ruminal stasis, lameness and recumbency. Eight of those attended had severe respiratory distress and subcutaneous emphysema. Haematological and biochemical results indicated leukocytosis with an attending lymphopaenia. Selenium deficiency was detected only in those animals which showed respiratory embarrassment and subcutaneous emphysema.

[Soft-tissue cervicofacial emphysema and pneumomediastinum caused by self injury].

A prison inmate was referred to us for diagnostic procedures and therapy due to a combination of pneumomediastinum with emphysema of neck and face. External injuries were absent and pathogenesis remained uncertain until thorough examination of the patient revealed two intraoral wounds, presumably from a needle, reaching into the maxillary sinus. This large subcutaneous emphysema of the face, neck and mediastinum was the result of an exaggerated Valsalva maneuver. With this self-inflicted injury, unknown to us, the prisoner achieved the desired immediate admission to hospital.

[Subcutaneous, pneumomediastinal, pneumopericardial emphysema and pneumothorax following retrosigmoid resection].

Pulmonary alveolar rupture can occur spontaneously or as a result of mechanical ventilation or other causes, and may give rise to bullae or emphysema without producing extrapulmonary air. Most but not all cases occur in patients with underlying lung disease. We describe a patient with no history of lung disease who underwent anterior sigmoid resection under combined (general/epidural) anesthesia. Soon after the patient awoke from anesthesia, subcutaneous, pneumomediastinal and pneumopericardiac emphysema developed, along with bilateral pneumothorax. We discuss the possible causes of extra-alveolar air was well as ways to detect and treat it.

Improvement in ejection fraction by hydrotherapy as rehabilitation in patients with chronic pulmonary emphysema.

BACKGROUND AND PURPOSE: It has been reported that breathing exercise by immersion in combination with expiring into water improved pulmonary function and blood-gas exchange in patients with chronic obstructive pulmonary disease (COPD). This effect may result from respiratory muscle exercise against hydraulic pressure and decreased dead space by increased sub-abdominal pressure. Increased cardiac function by bathing is suggested to contribute to the effect. To clarify the effect of the breathing exercise by immersion on cardiac function, a study was made of cardiac function during the exercise in patients with emphysema. METHOD: Echocardiography, respiratory function test and arterial blood gas analysis were performed during a two-month breathing exercise programme in a pool filled with 38 degrees C water for 12 patients (aged 70.9 +/- 9.1 years) with stable chronic pulmonary emphysema who were treated at our hospital between 1993 and 1996. The patients breathed in whilst standing in a pool and breathed out through the mouth while sinking the nose under water. This exercise was repeated for 30 min per day and continued for six days a week for two months. RESULTS: The ejection fraction increased significantly after each 30-minute exercise (N = 12; p < 0.01) as well as after the two-month exercise programme (N = 12, p < 0.05). Left ventricular end-diastolic and systolic dimensions at rest decreased significantly after the two-month exercise programme (N = 12, p < 0.01). The ratio of forced expired volume in one second to forced vital capacity (FEV1:FVC) increased and PaCO2 decreased following this programme (N = 12, p < 0.05). CONCLUSIONS: These results suggest that the breathing exercise by immersion is useful not only in treating emphysema but also in improving cardiac function.

Basilar hyperlucency in a patient with emphysema due to hypocomplementemic urticarial vasculitis syndrome.

Disproportionate emphysematous involvement of the lung bases, compared with the apices, sometimes called basilar hyperlucency, is an unusual radiographic pattern that has been reported primarily in patients with alpha-1 antitrypsin deficiency, but also in individuals with emphysema caused by intravenous injection of methylphenidate. We present a patient with emphysema associated with hypocomplementemic urticarial vasculitis syndrome and whose chest radiograph demonstrated basilar hyperlucency. To the extent that basilar hyperlucency has not been well recognized as a feature of hypocomplementemic urticarial vasculitis syndrome, this report extends the spectrum of causes of this unusual radiographic pattern of emphysema.

[Volume reduction surgery--a new treatment concept in advanced diffuse pulmonary emphysema].

Excision of large space occupying bullae in patients with emphysema is an accepted procedure if the underlying parenchyma is compressed and relatively normal. This operation may relieve symptoms of dyspnea and improve exercise tolerance. The volume reduction operation is based on different concept and designed for the diffuse type of emphysema. Resection of the most diseased lung in patients with marked hyperinflation may relieve thoracic distension and improve respiratory mechanics. We are currently evaluating prospectively the use of bilateral thoracoscopic volume reduction for patients with advanced, diffuse emphysema. During the last 1 1/2 years over 20 patients have been operated on. The average FEV1 was 765 ml/sec preoperatively and improved 40% within 3 months with a range of 0-100%. The 12 minute walking distance improved more than 100%. There was no perioperative mortality. Bilateral thoracoscopic volume reduction surgery is a palliative procedure but offers significant improvement in pulmonary function and exercise capacity for many patients.

Upper airway obstruction caused by massive subcutaneous emphysema.

Acute upper airway obstruction is a potentially life-threatening event. The most common causes include foreign body inhalation, thermal injury, inflammation, angioedema and trauma. Airway obstruction caused by submucosal extension of subcutaneous emphysema has only been previously reported once. We report the case of a patient who suffered a respiratory arrest as a result of hypopharyngeal and laryngeal swelling associated with massive subcutaneous emphysema.

Retroperitoneal and mediastinal emphysema as a complication of colonoscopy.

Retroperitoneal and mediastinal emphysema as a complication of colonoscopy, though infrequent, may occur. It is important to realize that this can be a benign clinical condition that will resolve with conservative management. A case of retroperitoneal emphysema after routine colonoscopy is reported with a review of literature and a brief discussion.

Subcutaneous emphysema of the lower extremity of gastrointestinal origin.

Two cases of subcutaneous emphysema of the left lower extremity secondary to perforations of the rectum ,nd sigmoid colon are presented. Although this is an extremely rare syndrome, the true incidence is probably higher, as some cases will be misdiagnosed as gas gangrene unless careful clinical and postmortem examinations are performed. Only rapid recognition of the probable origin of the gas, coupled with aggressive, definitive therapy, can prevent the usually fatal course of this condition. In the absence of trauma to the chest or infection in a previously normal leg, subcutaneous emphysema of a limb should alert the physician to the possibility of a gastrointestinal perforation as a source of the gas. Perforations of the gastrointestinal tract into the subcutaneous tissue can occur anywhere from the neck to the lower extremities.

Pneumomediastinum, pneumothorax and subcutaneous emphysema complicating MIS herniorrhaphy.

PURPOSE: Videoscopic herniorrhaphy is being performed more frequently with advantages claimed over the conventional open approach. This clinical report describes a pneumothorax, pneumomediastinum and subcutaneous emphysema occurring at the end of an extraperitoneal videoscopic herniorrhaphy. CLINICAL FEATURES: A 25 yr old ASA I man presented for elective extraperitoneal videoscopic hernia repair. Following intravenous induction with fentanyl, midazolam and propofol a balanced anesthetic technique using enflurane in N2O and O2 was used. Apart from a prolonged operating time (195 min), the procedure and anesthetic was uneventful. At the conclusion of the operation, prior to reversal of neuromuscular blockade extensive subcutaneous emphysema was noted on removal of the surgical drapes. Chest radiography revealed a pneumomediastinum and pneumothorax. A 25 FG intercostal tube was inserted and connected to an underwater seal drain. Sedation and positive pressure ventilation was maintained overnight to permit resolution and avoid airway compromise. The clinical and radiological features had resolved by the next morning and the patient's trachea was extubated. His subsequent recovery was uneventful. CONCLUSION: Pneumothorax and pneumomediastinum are well recognised complications of laparoscopic techniques but have not been described following extraperitoneal herniorrhaphy. In this report we postulate possible mechanisms which may have contributed to their development, including inadvertent breach of the peritoneum and leakage of gas around the diaphragmatic herniae or tracking of gas retroperitoneally. The case alerts us to the possibility of this complication occurring in patients undergoing videoscopic herniorrhaphy.
