Early electrocardiographic diagnosis of chronic cor pulmonale was attempted in the study of 312 patients with chronic pneumonia and in 251 normal individuals. In comparing the mean values of several ECG indices in chronic pneumonia, Stage 1, some signs with significant differences were revealed (amplitude of the PaVF wave, ratio of the hight of the PII and TII Waves, are of the PII wave). These signs appeared to be most informative. The following groups were singled out: 38 patients with chronic pneumonia, Stages 1 and 2 with signs of bronchospasm, and 53 persons with the same stages of the disease, but free of bronchial patency disorders. The ECG of these groups of patients was evaluated by means of the tables of electrocardiographic diagnosis of right atrial hypertrophy. The signs of overloading of the right atrium were revealed with statistical significance more often in patients with bronchospasm. The possibility of using this table for revealing early electrocardiographic signs of chronic cor pulmonale was also established; these signs include the amplitude of the PII wave greater than 2 mm and PaVF 1.5 mm, ratio of the hight of the PII and TII waves less than 0.75, the are of the PII wave greater than 0.09.

Hereditary mucoepithelial dysplasia is an autosomal, dominantly inherited disorder affecting all of the orificial mucosa with cataracts, follicular keratosis of skin, nonscarring alopecia, bouts of pneumonia, spontaneous pneumothorax, and terminal cor pulmonale. The oral lesion is a fiery red, flat or micropapillary-appearing mucosa most frequently involving the gingiva and hard palate. All oral and pharyngeal mucosa may be involved, however. Red scrotal mucosa of the tongue is common. Histologically, the oral mucosa shows a lack of cornified and keratinized cells, a decrease in the thickness of the epithelial cell layer, dyshesion, and dyskeratosis. Papanicolaou smears show lack of epithelial cell maturation, poikilocytosis, anisocytosis, large paranuclear cytoplasmic vacuoles, and cytoplasmic strand-shaped inclusions. Ultrastructural features include a paucity of desmosomes, intercellular accumulations of amorphous material, cytoplasmic vacuoles, and paranuclear lesions with strands of material resembling gap junctions and desmosomes. The condition most likely represents a basic defect in gap junction and desmosome formation.

Patients aged over 45 admitted to hospital with exacerbations of chronic bronchitis alone or in association with cor pulmonale, pneumonia, or respiratory failure were placed in one of three groups (men with hypoxia, men without hypoxia, and women). Patients within these groups were then randomly allocated to receive either standard drug treatment alone or standard drug treatment plus intermittent positive-pressure ventilation (IPPV). No significant differences occurred between the controls and patients receiving physiotherapy and IPPV in any group. We conclude that when a patient with chronic bronchitis and respiratory failure is deteriorating emphasis should be on correct diagnosis, fluid electrolyte balance, and nutrition together with oxygen treatment when necessary, rather than on additional physiotherapy.

Two uses of intermittent positive pressure can be distinguished: one supports inhalotherapy and the other longterm assisted ventilation. The apparatus can be connected to the patient either through mouth-piece or by tracheostomy. The main factors involved in the indication of assisted ventilation are the number of acute failures, hypoxemia, hypercapnia, cor pulmonale. In our department, 53 patients were kept under prolonged supervision before a decision was made to use assisted ventilation or not. This attitude seems absolutely necessary. An oxygen test of several hours provides very useful information. Finally, the authors review the indication of various ventilation methods (tracheostomy, oral) in relation to different chronic respiratory insufficiency etiologies (ie., chronic obstructive broncho-pneumonia, restrictive syndrome).

A group of 206 patients with the main forms of chronic nonspecific diseases of the lungs (chronic bronchitis, chronic pneumonia, and bronchiectasis--local and diffuse) was studied. The condition of pulmonary ventilation, bronchial patency, and hemodynamics of pulmonary circulation were analysed. Comparison of the data obtained in different groups of patients made it possible to determine the main peculiarities of the pathogenesis of pulmonary hypertension and formation of cor pulmonale.

A previously unrecognized autosomal dominant syndrome affecting oral, nasal, vaginal, urethral, anal, bladder, and conjunctival mucosa with cataracts, follicular keratosis, nonscarring alopecia, and terminal lung disease is described in a four-generation kindred of German extraction. Severe photophobia, tearing, and nystagmus in infancy heralds the development of keratitis, corneal vascularization, and lens cataracts. Repeated corneal transplants have failed. Red, periorificial mucosal lesions involving the above structures are noted by 1 year of age and may persist throughout life. Chronic rhinorrhea and repeated upper respiratory infections frequently progress to bilateral pneumonia accompanied by loss of hair, diarrhea, occasional melena, enuresis, pyuria, and hematuria. Spontaneous pneumothorax is frequent, terminating in fibrocystic-type lung disease and cor pulmonale. Women have had repeated abnormal vaginal PAP smears. Histologically the mucosal epithelium shows dyshesion, thinning of the epithelial layer, and dyskeratosis. Mucosal PAP smears show lack of epithelial maturation, cytoplasmic vacuoles and inclusions, and individual cell dyskeratosis. Histochemically there is a lack of cornification and keratinization. Ultrastructural studies show lack of keratohyalin granules, a paucity of desmosomes, intercellular accumulations, cytoplasmic vacuolization, and formation of bands and aggregates of filamentous fibers and structures in the cytoplasm resembling desmosomes and gap junctions. The condition is probably a panepithelial cell defect of desmosomal and gap junction structure most prominently affecting mucosal epithelia associated with an increased susceptibility to a variety of adventitious organisms.

Sclerosing mediastinitis is excessive production of fibrous tissue in the mediastinum. Its most common manifestations, widening of the mediastinum and superior vena caval obstruction, are the only roentgenographic findings generally recognized to be associated with this disease. Analysis of 29 cases of sclerosing mediastinitis and review of the literature reveal that compression of mediastinal organs by constricting bands of collagen may cause various roentgen manifestations including bronchial or tracheal obstruction leading to atelectasis or obstructive pneumonitis, pulmonary venous obstruction, pulmonary artery obstruction, esophageal obstruction and nerve entrapment. The most common abnormality seen on the chest roentgenogram, mediastinal widening, is usually superior and especially right paratracheal in location. Superior vena caval compression is smooth and tapered rather than irregular as in malignant disease. Pulmonary venous and arterial obstruction may cause cor pulmonale and death, although the other manifestations are usually not life-threatening. The most common causes of sclerosing mediastinitis are generally considered to be granulomatous diseases, especially histoplasmosis, although many other causes have also been suggested. The disease may be regarded as an inappropriate response to one of several stimuli.

A grand mal convulsion occurred in a patient with decompensated cor pulmonale. Although only modest doses of oral theophylline were being administered at the time of the convulsion the serum theophylline level was markedly raised and the theophylline clearance was very low. After treatment for cor pulmonale theophylline clearance improved; however, with the subsequent onset of fever and pneumonia the clearance decreased again, illustrating the potential lability of theophylline clearance.

The present report describes an infant with severe combined immunodeficiency and cartilage-hair hypoplasia whose lymphocytes responded to thymosin in vitro. Immunologic evaluation was undertaken at 4 1/2 months of age following a history of recurrent severe infection. Family history included three cousins who died in early infancy, one from streptococcal meningitis and pneumonia, one from generalized varicella, and another from reticuloendotheliosis. Quantitative immunoglobulins were markedly depressed: IgG 141, IgA 0, and IgM 24 mg/100 ml. There was an absolute lymphopenia, multiple skin tests were negative, and in vitro lymphocyte responses to mitogens and antigens were depressed. Spontaneous E rosette determinations were 21% compared with control values of 65.7%. Erythrocyte adenosine deaminase (ADA) activity was normal. The patient's E rosette formation increased in the presence of thymosin, fraction 5, reaching a maximum of 56% with a concentration of 500 mug thymosin. Blastogenic responses to phytohemagglutinin also increased in the presence of thymosin. Transplantation of 24-week fetal thymus in Millipore diffusion chambers and subsequently transplantation of 18-week fetal thymus by intraperitoneal injection was accomplished. E rosettes increased to 35-40% and blastogenic responses to mitogens increased. Eight days after the second transplant the patient underwent a mild graft vs. host reaction which subsided after 1 week and mitogen blastogenic responses again increased to 5-8 times previous values, but still well below control ranges. Repeated episodes of pulmonary infection ensued, cor pulmonale resulted, and the clinical course was relentlessly downhill with the patient expiring from respiratory failure 5 months after transplantation.

Among 110 patients with dermatomyositis cardiovascular pathology was found in 77, and only in 37 of them it was attributable to the underlying pathology. In all of these patients myocardial lesions were found, that manifested themselves most frequently by non-specific ECG changes. Cardiac insufficiency and arrhythmias were revealed less frequently, mainly during exacerbations of the pathological process. Only in one patient endocarditis was diagnosed, and in two others elements of chronic cor pulmonale due to pneumonitis. In 18 patients signs of moderate myocardial dystrophy developed after a long-term therapy with corticosteroid hormones. A study of the central haemodynamics in 20 patients with dermatomyositis revealed a tendency towards a hyperkinetic state of the circulation in those patients who had the most sereve muscle syndrome. Angioscopy of the bulbar conjunctiva revealed the changes that persisted even during the remission period, achieved by means of active steroid therapy.
