Pneumothorax during operation is always clinically serious. The symptoms are usually sudden
cyanosis
, accompanied by cardio-vascular collapse and difficulty or even impossibility to ventilate owing to increased pressures of insufflation. Immediate or secondary bilateral pneumothorax is relatively common, then may appear associated complications such as subcutaneous
emphysema
or pneumo-mediastinum. Early diagnosis is necessary to apply simple treatment and avoid a course which may be rapidly fatal. The authors report 3 cases of pneumothorax during anesthesia and consider the clinical forms, the mechanisms and causes of this accident.

Peripheric circulatory disturbances and acrocyanosis in Moselle vinedressers injured by arsenic. During the years 1972--1975 a total number of 100 vine-dressers came for medical treatment because of late injures caused by arsenic intoxication. That is an average of 400 examinations per year 1600 control examinations within four years. These patients belonged to the age-classes 1890--1923, and the average time of exposure to arsenic was 20 years. After years of being exposed to arsenic, and even years after the exposure to it has stopped, there are those so-called late injures caused by arsenic. There are typical arsenic melanisms on the forehad-temple-rim where the hair begins to grow, on the nape of the neck, on the shoulders, chest, arms, and on the back of the hands which pass into precanceroses and carcinomas. The average time until the first late injuries caused by arsenic occur is 26 years. However, there have been latence periods of up to 50 years. This depends mainly on the amount of arsenic absorbed during the time. There are skin alterations which resemble very much an acrodermatitis chronica atrophicans Herxheimer. Histological examinations rather showed the symptoms of an endangiitis obliterans with atrophy of the cutis. These symptoms were found in 60--70% of the 50--60 years old patients, in 80--90% of the 60--70 years old patients, and in 90--95% of the 70--80 years old patients. Simultaneously there are distinct peripheric circulatory disturbances,
cyanosis
of the lips, dyspnoea, and an
emphysema
together with typical cardiac insufficiency. Foot and finger pulse are distinctly slower, and the temperature of the skin is remarkably lower. While people grow older the
cyanosis
gets worse. With a control group of patients who hadn't been exposed to arsenic these symptoms had only been found on 1--2%.

Clinical symptoms such as mediastinal and tissue
emphysema
, impaired inflow with
cyanosis
and extreme dyspnoea, signs of tension pneumothorax suggest rupture of a bronchus; nonstop loss of air via intercostal drainage is an almost certain sign and bronchoscopy provides the final proof. Injury to smaller bronchi may remain asymptomatic. 1,600 persons were treated for chest injury during the past 17 years, 7 of them on account of a ruptured bronchus. The right and left main bronchus were involved in 4 cases and one case respectively. The bronchus of the right upper lobe and the trachea were ruptured in one case each. Once the injury has been diagnosed surgical repair should follow quickly, although the results of anastomoses performed at a later stage were also satisfactory. Closure was by chromcut knotted sutures. Partial pneumonectomy is indicated only if damage to the lungs is extensive. The postoperative respiratory function of the injured lung was satisfactory in all cases.

A young woman with hypoplastic right heart syndrome developed a carotid body tumor at age 28. High altitude habitation is known to predispose to hyperplastic and neoplastic carotid bodies;
emphysema
and congenital cyanotic heart disease have recently been shown to induce hyperplasia of this oxytrophic tissue. Therefore, a link between congenital
cyanosis
and carotid body tumor is suggested by this patient. Carotid bodies are nonchromaffin paraganglionic analogues of the adrenal medulla. Congenital
cyanosis
has an association with pheochromocytoma. In the cyanotic milieu carotid body tumor may be a histological analogue of pheochromocytoma.

Perforation of the hypopharynx due to traumatic attempted endotracheal intubation usually occurs during resuscitation efforts under poor conditions, but may occur even under optimal conditions due to improper technique. The implication of the appearance of subcutaneous
emphysema
in the neck,
cyanosis
, or pneumothorax during or following attempts at endotracheal intubation should be known. Direct laryngoscopy may be helpful in establishing the injury but early radiological examination is necessary for diagnosis of the site and extent of the perforation. The radiological contribution appears to be decisive in the choice of treatment. The radiological findings and the considerable morbidity observed in 6 cases of hypopharyngeal injury are described.

The congenital lobar
emphysema
has no uniform etiology. We can however suppose that malformations especially of the cartilage are of importance. The whole lobe is mostly involved, with predilection of the left upper-lobe. The symptomatology of the congenital lobar
emphysema
is a manifold one. Striking are respiratory embarrassement with dyspnea and
cyanosis
. For the diagnosis an X-ray is necessary. Remarkable is a transparent lung in which you can still see an unimportant pattern. For the differential diagnosis et first congenital cysts come in question. By intercurrent infections a sudden severe deterioration can result, also if the cases show a favourable course. The method of choice is a timely operation, necessary is the resection of the affected lobe. This is a report of 17 own observations. In 11 cases we found a congenital lobar
emphysema
, in 6 cases congenital lung-cysts. We could examine 10 patients till to eleven years from the beginning of the disease. All the children had a normal development, except of insignificant residues.

The aetiology of congenital lobar
emphysema
is not always evident. In the group with demonstrable check-valve mechanism, which allows the air to enter but not to leave the lung, there is either internal stenosis or external compression of the bronchus. When no cause can be found, the condition is called idiopathic, although in some cases alveolar fibrosis has been demonstrated, the check-valve mechanism being in these cases at an alveolar level. In the small group of rare cases of bronchial atresia, air which enters through a collateral ventilation cannot be removed by the same route; in these case too, the check-valve mechanism exists at the alveolar level. Five cases of "congenital lobar emphysema" are presented. One case showed no bronchial anomaly; another case showed an increase in interstitial connective tissue in the lung; tow cases showed hypoplasia or absence of bronchial cartilage; in one case, bronchial atresia was found at operation. Infants show a typical symptomatology of dyspnoea and
cyanosis
, and a typical chest X-ray with unilateral radiolucency and a delicate lung pattern, collapse of surrounding lung tissue, and mediastinal hernia. In older children, the diagnosis is made either incidently or following a complication. The condition is usually found in the left upper and the right middle lobe. Treatment is surgical and consists of resection of the emphysematous segments.

Major fracture of the intrathoracic airway following closed chest trauma is a potentially lethal injury which can be repaired successfully if the diagnosis is made early, Cough, dyspnea
cyanosis
, hemoptysis, mediastinal
emphysema
, or pneumothorax not responding to drainage via intercostal tube and a deterioration of the patient's clinical condition out of proportion to the apparent closed chest injury, should alert the clinician to the possiblity of this entity. This report describes the findings in a patient with a longitudinal disruption of the entire intrathoracic trachea and the findings in a second patient with complete transection of the right main bronchus. Each was repaired primarily, with eventual recovery, The principles of management of this difficult group of injuries are reviewed.

The objectives of this study were to use pulmonary function tests, blood gas measurements and bronchoalveolar lung lavage (BAL) to characterize lesions in the respiratory tract of young adult male Wistar rats as a result of a 5-day exposure (6 h/day) to 0, 1.1, 6.2, 15 or 26 mg n-butyl isocyanate (n-BIC)/m3 air. Further objectives were to probe the diagnostic sensitivities of these procedures in comparison with more traditional evaluations (clinical observation, lung weight, histopathology). Measurements were performed during post-exposure weeks 2 and 5. Most rats exposed to 26 mg/m3 died or were sacrificed in a moribund state during post-exposure week 2. All other rats survived the exposure regimen. In rats exposed to 15 and 26 mg/m3 a significant decrease in body weight, laboured breathing, hypoactivity, nasal discharge,
cyanosis
, and hypothermia were observed. Pulmonary function measurements revealed increased total lung capacity (TLC) and residual volume (RV), decreased forced expiratory flow rates and quasi-static compliance in rats exposed to 26 mg/m3. At the end of the observation period rats exposed to 6.2 and 15 mg/m3 air were hyperresponsive to an acetylcholine bronchoprovocation aerosol. Arterial blood gas measurements revealed an arterial hypoxia and an increase in venous admixture, suggesting a severe mismatch of the ventilation-perfusion relationship. Biochemical and cellular components in BAL fluid (BALF) indicated a concentration dependent and protracted increase of polymorphonuclear leucocytes and further inflammatory parameters. In the 1.1 mg/m3 group BALF parameters were not significantly elevated. The major histopathological lesions of the lung were thickening of septa,
emphysema
, and intra-alveolar oedema in rats exposed to 26 mg/m3.(ABSTRACT TRUNCATED AT 250 WORDS)

A 76-year-old man was referred to our hospital with complaints of productive cough, dyspnea and peripheral
cyanosis
. The chest X-ray film indicated the pulmonary
emphysema
and acute bronchitis, but no abnormal intracardiac calcification. The electrocardiogram revealed a peaked P-wave, complete left bundle branch block, and ventricular premature contraction. Chest tomography demonstrated abnormal intracardiac calcium deposition in the right heart region. Two-dimensional echocardiography revealed the tricuspid annular calcification in the postero-lateral portion, showing a synchronous movement with tricuspid annular motion throughout the cardiac cycle. The size of calcification was 10 x 14 mm. The tricuspid valve showed no significant regurgitation. Left ventricular dilatation, associated with mild mitral regurgitation and impairment of systolic function (EF = 49%) was revealed by echocardiography. Serum examination revealed positive in Wassermann reaction. This case of tricuspid annular calcification might be caused by atherosclerotic degenerative change related to the aging process, or by an unknown mechanism related to pulmonary
emphysema
.
