Spontaneous pneumomediastinum is a relatively rare disease, the clinical signs of which may be misleading, and the physiopathology is still unknown. The authors report 7 cases collected over a period of 3 years and note the etiology, the clinical findings and the X-ray findings. The disease often affectsyoung sybjects, without any sex predominance. The initial symptom is thoracic pain and is often accompanied by dispnea. Subcutaneous emphysema only appears secondarily and may be mild. The association with pneumothorax is not rare. Among the etiological circumstances, pneumomediastinum often occurs after an effort or a respiratory infection with dyspnea. The diagnosis depends on the discovery of subcutaneous emphysema and on radiological signs in A.P. and lateral chest views. Treatment should be as conservative as possible in the usual benign forms. It should be limited to bed rest, analgesics and sedatives. In severe cases, supra-sternal drainage permits decompression of the mediastinum. The physiopathological mechanisms are discussed, but the usually accepted theory is rupture of an alveolus into the pulmonary interstitial tissue. The pressure gradient necessary for this rupture may be due to variations in alveolar or vascular pressure.

Fractures of the clavicle, while common, are associated with few serious complications. The authors report the case of a 29-year-old man with a simple fracture of the middle third of the clavicle that was associated with a 30% pneumothorax. The force and mechanism of the injury, severe pleuritic pain and reduced breath sounds suggested the diagnosis which was confirmed roentgenographically. The possibility of pneumothorax must be considered in any patient with a fracture of the clavicle, especially in the unconscious patient who has sustained multiple injuries.

Find needle biopsy of tumours of the lung and mediastinum represents an accurate method which can be performed pain-free and rapidly without undue effort and cost. It can be repeated at any desired time. Absolute contraindications are very rare. This method can be applied also in outpatients, provided certain precautions are observed. In many cases, it eliminates the far greater risk of exploratory thoracotomy. Both peripheral and central lung tumours, including mediastinal tumours, can be identified and differentiated. More than nine out of ten bronchial carcinomas are clearly identified. In 60--70% of all punctures, the pathologist is successful in accurately establishing the type of cell involved. As far as the patient himself is concerned, the method hardly involves any pain and does not cause much discomfort. A frequent complication is the usually asymptomatic pneumothorax, which occurs in less than 30% of all punctures. In a few rare cases, suction drainage will be necessary. Generally speaking, and in all other respects, fine needle biopsy is a low-risk procedure.

In patients with chest pain somatic pain (thoracic wall pain) has to be differentiated from visceral pain (organ pain). History and careful physical examination are diagnostic in most cases. Presented are rare and not well-known diseases like valvular aortic stenosis, idiopathic hypertrophic subaortic stenosis and the mitral valve prolapse syndrome. Not seldom they are masked by angina pectoris-like symptoms, although in general the coronary arteries are normal. In acute chest pain differential diagnostic considerations have to include lung embolism, acute pericarditis, spontaneous pneumothorax, acute dissecting aneurysm of the aorta and diseases of the gastrointestinal tract as well. Only after exclusion of any organic cause the diagnosis of "effort syndrome" may be made.

An assessment of morbidity in near-drowning was made from a review of emergency room and hospital records of 72 patients, ages 9 months to 20 years, who suffered near-drowning during the period January 1972 through June 1974. Fifteen patients (21% evidenced severe anoxic encephalopathy; the remainder had no detectable neurologic deficits. Hypoxemia was demonstrated in 56 patients. Severe acidosis was not present unless respiratory failure occurred. Neither electrolytes, red blood cell hemolysis, nor cardiac arrhythmias presented a problem. Respiratory complications included pulmonary edema, aspiration pneumonia, atelectasis, shock lung, pneumothorax, and pneumomediastinum. All children requiring cardiopulmonary resuscitation in the emergency room suffered anoxic encephalopathy. The occurrence of seizures, fixed and dilated pupils, flaccid extremities, and lack of response to deep pain in the emergency room had almost universal correlation with resultant severe anoxic encephalopathy, as did a submersion period of six or more minutes. The morbidity of near-drowning is significant with regard to the number of children affected and the severity of the central nervous system insult received. The statement by the American Heart Association that resuscitative efforts in children should be continued for periods longer than ten minutes needs reevaluation, since neurologic recovery did not occur in any child requiring cardiopulmonary resuscitation (CPR) in the emergency room. More importantly, new methods of cerebral resuscitation need to be developed and established. In short, medical personnel need to think in terms of cardiopulmonary cerebral resuscitation (CPCR) rather than in terms of CPR.

Preventive medicine is the primary responsibility of every physician. When prevention fails and therapeutic measures are required, the initial approach tends to be along a conservative line. When this approach fails, surgical intervention becomes a necessity. Surgical patients, both pre- and post-surgical, may be moved by aircraft providing that one is aware of the hazards in a hostile atmosphere in which pressure and temperature change with increasing altitude. Air or gas trapped in the body cavities expands in direct proportion to the decrease in pressure. This increased volume becomes significant at 5500 m, where the volume of air or gas in the body is doubled. Quite apart form intense discomfort and actual pain caused in certain types of injury, this expansion of gas at high altitude may constitue a real danger, such as in the probability of rupturing a recently sutured intestine and, in cases of pneumothorax, by disturbance of cardiopulmonary dynamics. Thus, aeromedical evacuation of the surgical patient becomes a challenge to those responsible for the medical care between the originating and destination hospitals.

Twenty locally advanced lung cancers were treated by hyperthermia in combination with radiotherapy between November 1980 and January 1990. All tumors selected had invaded or were in contact with the chest wall, so that transcutaneous insertion of thermal probes into the tumor was possible. Using an 8 or 13.56 MHZ RF capacitive heating device, hyperthermia was given once or twice a week after irradiation for 30-60 min per session (1-12 sessions in total). Radiotherapy was delivered at dose of 13.6-70 Gy. The thermal parameters analyzed were a) maximum, average, and minimum intratumor temperatures (Tmax, Tav, and Tmin), which were recorded at the termination of each treatment, and b) the percentages of the intratumor points that exceeded 41 C (%T greater than or equal to 41 C). The mean +/- SD for Tmax, Tav, Tmin, and %T greater than or equal to 41 C was 42.9 +/- 1.7 C, 41.6 +/- 1.2 C, 39.7 +/- 1.1 C, and 56.2 +/- 25.8, respectively. Larger tumors showed higher thermal parameters than the smaller tumors. Of the 12 tumors treated by definitive therapy, 2 (17%) achieved CR, 7 (58%) PR, and 3 (25%) NR. Four of 10 tumors that did not achieve CR showed large intratumor low density areas on post-treatment CT, reflecting massive coagulation necrosis. Higher thermal parameters were closely related to the appearance of low-density areas but not to changes in tumor size. Four tumors treated preoperatively were successfully resected 2 weeks after thermoradiotherapy, whereas four palliatively-treated tumors showed no regression. The side effects associated with hyperthermia were pain in 12 patients (60%) and dyspnea in 3 (15%), all of which resolved after termination of treatment. A skin abscess and a pneumothorax attributed to thermal probe insertion were observed in one patient each. These results indicate that regional RF capacitive hyperthermia is clinically feasible for local treatment of selected lung cancers.

From September, 1991, to June, 1992, 32 cases of pneumothorax were operated with thoracoscopy (video surgery). The indication was established for second recurrence in 6 cases, first recurrence in 14 cases, a persistent bulla or a lung failing to return to the wall after a first pneumothorax in 5 cases, and in the presence of a large pulmonary bulla on radiographs or CT scans during an initial episode in the last 7 cases. Thoracic CT was performed in 18 cases and demonstrated a system of bullae in 14 (13 in the apical segment and 1 in the segmentum apicale). The procedure included exeresis of the bullae on endo-GIA with apical and posterolateral parietal pleurectomy. In two cases, conversion into axillary thoracotomy was required because of extensive pleural adhesion in one case and of a technical problem in the other. The average duration of surgery was 72 mn. The thoracic drains were removed on the 2nd and 3rd postoperative days. Partial pleural detachment occurred in two cases, one on the 4th day and the other on the 5th day after surgery, with spontaneous return to the wall on the 8th day in both cases. The average stay in hospital was of 6 days. All patients were examined 15 days after discharge with a control radiograph, which was normal in all cases. No patient complained of parietal pain when no conversion into thoracotomy was made.

The greater splanchnic nerves are largely responsible for innervation of the supramesenteric viscera; their section is known to be efficient to relieve pancreatic pain. Transhiatal splanchnicotomy (THS) is easily performed through a midline laparotomy. The nerve trunks are readily identified in the submediastinal space, far from the pancreatic cancer motivating splanchnicotomy, and can be sectioned safely and completely. After carrying out an anatomic study to determine the level of origin and mode of constitution of the greater splanchnic nerve trunk and its relations to the posterior and lower mediastinum, 51 patients underwent THS for intractable pain caused by unresectable pancreatic adenocarcinoma. THS alone was performed in 22 cases. THS was performed in association with biliary tract diversion or gastroenteroanastomosis in the other cases. All tumors were considered unresectable during surgery, and no patient was operated on with the sole purpose of performing THS. Two deaths (3.9%) were unrelated to THS. Specific morbidity was 6% (one pneumothorax, one chylothorax, and one splenic injury). Immediate postoperative functional results were good in 86.3% of patients treated by THS alone (group 1) and in 80.7% of patients treated by THS and bypass (group II). Functional results decreased to 72.7% in group I and 62.1% in group II, 3 months after surgery. In conclusion, THS appears to be an efficient technique for relief of pancreatic neoplastic pain and need not be combined or confused with medical percutaneous methods of neurolysis.

Patients with Paragonimiasis westermani show a typical ring form or nodular shadow on chest X-ray, cough, sputum, and hemosputum. Recently, case reports of Paragonimiasis westermani, accompanied by pneumothorax and pleural effusion, as for Paragonimiasis miyazakii, have been increasing. Paragonimus westermani often causes an ectopic infection in various organs such as the peritoneal cavity, pleural cavity, pericardium, liver, adrenal gland and brain. Cutaneous paragonimiasis is considered one of the typical forms of ectopic infection in its earlier phase, but a few unexpected cases of cutaneous Paragonimiasis westermani have also been reported. A 68-year old man, who had never eaten fresh-water crab or raw sliced meat of wild boar, noticed subcutaneous induration of the abdominal wall. The induration had been gradually moving upwards and to the right from the infraumbilical region for over 20 days, and then disappeared at the right upper lateral abdominal wall. Eight months later, he developed severe pain in the right lower chest, and a chest X-ray showed right pleural effusion. Laboratory examinations revealed eosinophilia (WBC 3940/mm3, eosinophil 9%), elevated ESR, and an elevated serum total IgE level (5517 IU/ml). Ouchterlony's double diffusion test performed with the patient's serum in agarose showed strong bands toward Paragonimus westermani antigen, compared to Paragonimus miyazakii antigen. Immunoelectrophoresis with the patient's serum showed specific bands toward Paragonimus westermani antigen. This patient was finally diagnosed as having Paragonimiasis westermani infection, and he responded to praziquantel administration. The clinical course of this patient appears to be rare in cases of Paragonimiasis westermani infection. The clinical course of this case resembled some cases of Paragonimiasis miyazakii infection.(ABSTRACT TRUNCATED AT 250 WORDS)
