The mean ages of 10 calves with tracheal collapse were 2.7 weeks at onset of clinical signs and 9.4 weeks at presentation for treatment. Inspiratory and expiratory dyspnea and stunted growth were the most common clinical signs. There were abnormalities of the cranial ribs consistent with healing fractures with redundant callus in eight lateral thoracic radiographs. Tracheal collapse in calves may result from cranial thoracic trauma during or soon after birth. Short polypropylene ring prostheses made from 60 ml syringe barrels were placed on the tracheas of four calves with cervical tracheal collapse. There were cranial rib masses in all calves and resection of the right first and second ribs was necessary in one calf to allow placement of prostheses. Dyspnea was relieved in all calves. One calf died of unrelated causes in year 3, and one calf had recurrence of clinical signs at month 5 and was euthanatized. In both calves, tracheal stenosis resulted from continued growth and infolding of the trachea within the constraints of the prostheses. One calf was alive at month 11, and one calf died of acute bronchopneumonia on day 2. Removal of tracheal prostheses in calves is recommended after 2 to 3 months if clinical signs recur.

A 55-yr-old male with carcinoma of bladder received transurethral coagulation (TUC) under epidural anesthesia. A few min after the operation, he went into anaphylactic shock during irrigation of urinary bladder with thrombin solution. The symptoms were epigastralgia, circulatory collapse, skin rashes over the whole body and dyspnea. Oxygen inhalation and iv administration of epinephrine and steroid were performed, and his general condition improved within several hours. On the 2nd day after recovery from the anaphylactic shock, the patient received prick test on several agents which he had been given during operation. Prick test and RAST (radioallergosorbent test) on thrombin were positive. Based on our experience, thrombin may act to produce anaphylactic reaction. Although anaphylactic shock following topical thrombin is rare, we feel that thrombin should not be used without prick test.

Endobronchial tuberculosis is not as well-known to internists as tuberculosis involving the lung parenchyma. Five cases with this condition are reported to illustrate the varied clinical manifestations. The presenting features of the 5 cases were lobar or lung collapse, unresolved pneumonia, dyspnoea and stridor. Bronchostenosis developed in 2 patients many years following chemotherapy, while stenosis of the trachea developed in one patient during chemotherapy. In another patient, the tuberculous granulation tissue simulated a lung cancer at bronchoscopy. Diagnosis can be difficult as endobronchial tuberculosis can occur in the absence of chest X-ray abnormality and sputum smear may also be negative for acid fast bacilli (AFB). Therefore, bronchoscopy should be done when the condition is suspected in a patient who has unexplained cough, wheezing, dyspnoea or haemoptysis. The modalities of treatment for fibrostenosis of a large airway include surgical resection followed by anastomosis, balloon dilatation, laser photoresection or a combination of both procedures.

Metabolic fatigue is a characteristic muscle response to intense exercise that has outstripped the rate of ATP replacement. The accumulation of metabolic by-products, namely hydrogen ions and diprotonated phosphate, interferes with actin-myosin interaction, effectively preserving muscle ATP levels by preventing further ATP hydrolysis. Muscle force and metabolite concentrations return to normal in about 5 minutes. Less intense exercise causes a more subtle, non-metabolic fatigue due to a still-undefined disturbance of excitation-contraction coupling, which can last for several hours. In this type of fatigue, greater effort is required to generate submaximal forces. Endurance exercise is mainly limited by the size of muscle glycogen stores and how efficiently they are used. Endurance training permits an athlete to work aerobically at high rates, consuming a mixture of lipid and carbohydrate fuels. When muscle glycogen is used up, exercise can only continue at the relatively low rate supportable by lipid metabolism. Anaerobic exercise is also limited by subjective factors such as dyspnoea and muscle pain, which have objective determinants. Extremely prolonged exercise can lead to general collapse because of dehydration, hyperthermia, or hypoglycaemia. None of these factors explains the phenomenon of asthenia, a subjective sense of exhaustion that produces no objective impairment of physical performance. The metabolic myopathies are experiments of nature that promise to shed new light on the biochemical basis of muscle fatigue. This will require quantitative studies of the kind provided by topical magnetic resonance spectroscopy, correlating physiology and metabolism in vivo.

A case of severe rhabdomyolysis with extensive myocardial involvement in a 32 year old alcoholic man is reported. He referred effort dyspnea for the last eight months which worsened thirteen days before his death. Admitted at the institute he was obnubilated and dyspneic. Massive pulmonary thromboembolism was suspected and heparin was given. He was then transferred to our intensive care unit in circulatory collapse. A chest Rx showed cardiomegaly. A Swan-Ganz catheter was introduced and abnormal parameters corrected. Evolution was complicated with acute cholecystitis, nosocomial bronchopneumonia and hypoxic brain damage. A net reduction of cardiac size as judged by a chest roentgenogram was noted in the final days. Necropsy showed skeletal and cardiac rhabdomyolysis, early alcoholic cirrhosis, diffuse peritonitis and bronchopneumonia. To our knowledge, this case is the first in the literature to provide anatomical evidence of cardiac rhabdomyolysis, a fact which was suspected on clinical grounds but had not been proven.

A 60-pack-year smoker presented with cough, dyspnea and orthopnea of three months' duration. Spirometry revealed severe reduction in maximal expiratory flow; CT of the chest and bronchoscopy demonstrated expiratory collapse of a mid-tracheal segment, and a presumptive diagnosis of tracheomalacia was made. A right lateral thoracotomy was performed to resect the unstable segment and improve maximal expiratory flow. Diffuse major airway disease with absence of cartilaginous rings from the thoracic inlet to the mainstem bronchi was encountered. The trachea and mainstem bronchi were stented externally. A high resistance to airflow and absence of expiratory flow limitation were present, suggesting a fixed rather than variable intrathoracic obstruction of major airways. This case illustrates some potential pitfalls in preoperative assessment of patients with tracheomalacia. Recordings of airway pressure and flow during mechanical ventilation are useful in distinguishing between fixed and variable intrathoracic obstruction and may complement tests of airway anatomy.

Tracheal collapse and bilateral laryngeal paralysis were diagnosed in an 8-month-old Cocker Spaniel that had acute onset of dyspnea and cyanosis. Surgical exploration of the mediastinum revealed an abscess involving the ventral wall of the trachea immediately caudal to the thoracic inlet. Both recurrent laryngeal nerves were entrapped in fibrous tissue surrounding the abscess. The dog recovered after tracheal resection and anastomosis and freeing of the entrapped nerves. The peritracheal abscess was suspected to have been the result of esophageal perforation secondary to foreign body penetration.

Medical records, radiographs, and bronchial cytologic abnormalities of 65 cats with bronchial disease were reviewed. Bronchial disease was defined as abnormality of the lower airways to the exclusion of disease originating or mainly involving the alveoli, interstitium, vasculature, or pleura. Cats with bronchial disease were more likely to be female and older. Siamese cats were overrepresented and had more chronic disease. In order of frequency, the following clinical signs were reported: coughing, dyspnea, occasional sneezing, wheezing, and vomiting. Radiography revealed prominent bronchial markings, with some cats having collapse of the middle lobe of the right lung (n = 7), overinflation of the lungs (n = 9), or aerophagia (n = 13). Of 65 bronchial washes, 58 were considered exudative, with the predominant cell type being eosinophil in 24%, neutrophil in 33%, macrophage in 22%, and mixed population of cells in 21%. Cultures for bacteria were considered positive in 24% of the cats. Circulating eosinophilia was not helpful in predicting the predominant cell type in bronchial cytologic exudates. Hyperproteinemia without dehydration was present in a third of the cats, indicating an immunologic response. Half the cats had resolution of clinical signs, whereas half the cats required continuing medication with bronchodilators, antimicrobial agents, or corticosteroids.

We report the results of palliative treatment of non-resectable obstructing endobronchial carcinoma by bronchoscopic implantation of radioactive gold grains in 18 patients. Dyspnoea and collapse of a lobe or a lung were successfully treated in 13 cases where tumour was locally confined to a main or lobar bronchus. The response was maintained until death in nine of these patients but obstruction recurred in four longer surviving patients with tumours of main bronchus after a mean interval of 6 months. Treatment was less successful in five patients with tumour extending onto the trachea. The low penetration of interstitial radiation offers the advantage that normal lung and other tissues are not damaged, so that the procedure can be used in patients previously submitted to external radiotherapy.

Air embolism, diagnosed by clinical therapeutic trial in the Navy hyperbaric chamber, occurred in a woman having labor induced by hypertonic saline for intrauterine fetal death at 25 weeks' gestation. 20 hours after saline administration, and 2 hours after 2 mU/minute diluted oxytocin was started, she had a sudden cardiovascular collapse with cyanosis and dyspnea. She was resuscitated by ventilation by mask and iv fluids. When she regained consciousness she was cortically blind. During treatment by the Navy's protocol, 30 minutes of compression at 6 ATA alternating cycles of 100% oxygen and air after rapid decompression to 2.8 ATA for 5 hours 19 minutes, there was a dramatic improvement in vision. After treatment, she showed left hemianopsia with macular damage. A year later only slight loss of left visual field remained. Air embolism can only be differentiated from amniotic fluid embolism by demonstration of amniotic fluid or fetal components in the maternal central circulation, or a therapeutic trial in a hyperbaric chamber. It is safer to try the pressure chamber immediately.
