The clinician usually determines the measures to be taken on the basis of clear symptomatics represented by more or less pronounced cyanosis. The author is able to show that the negative roentgenogram is not a reliable means of excluding pulmonary fibrosis, in contrast to functional pulmonary studies. If breathing physiology is normal and the roentgenogram does not reveal any abnormal findings, further invasive procedure will not be required. However, if functional investigations are positive and indicate a diffuse pulmonary disease, then our criteria point to open pulmonary biopsy, since prognosis and possible causal treatment largely depend on the histology.

The author describes a case of ocular affection in pulmonary fibrosis with an obscure aetiology and subsequent secondary polyglobulia. In addition to cyanosis of the mucosae and conjunctive the authors detected also cyanosis of the retina of both eyes and thrombosis of the central retinal vein on the right and prethrombosis on the left. The author gives an account of the differential diagnosis of diseases with a similar ophthalmological finding.

Respiratory infections of 19 subjects of advanced age and/or with underlying respiratory disease were treated with cefoperazone (CPZ) and its clinical effects were studied. Sixteen subjects suffered from respiratory tract infection and 3 subjects had pneumonia. The age of the subjects ranged from 39 to 77 years with the mean of 63.8, 7 of them being more than 70 years of age. The underlying respiratory diseases included chronic pulmonary emphysema in 6 subjects, diffuse panbronchiolitis in 3, bronchiectasis in 3, silicosis in 2 and one each of chronic bronchitis, pulmonary fibrosis, lung cancer and old pulmonary tuberculosis. One case, 75 years of age, had renal insufficiency. The daily dose of CPZ was 4 grams in 18 of the 19 subjects and the duration of administration ranged 5 to 22 days. The remaining 1 subject received 2 g of CPZ daily for 6 days. Clinical effects were judged from the changes in fever, cough, amount of sputum, dyspnea, rales, cyanosis, chest X-ray, white blood cell counts, CRP, erythrocyte sedimentation rates and results of sputum culture. Clinical effects were good in 16 subjects, fair in 1, and poor in 2. Bacteriological follow-up was carried out in 13 subjects. Infecting bacteria were eliminated from 5 subjects, reduced in 2 and, in 4 subjects, they were replaced by other bacteria. In 1 subject, P. aeruginosa was isolated from sputum even after the treatment with CPZ, and in another subject H. influenzae relapsed immediately after the cessation of the CPZ treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

A progressive pulmonary disease resulting in severe respiratory failure and death in an average of 3 weeks was diagnosed in 11 young Dalmatian dogs. The dogs were from 4 litters, all genetically related by a common ancestor. The initial clinical signs were tachypnea and noisy respiration. Respiratory distress developed shortly before death and was characterized by strenuous and rapid respirations, along with cyanosis and vomiting. On blood gas analysis, there were severe arterial hypoxemia, hypercapnia, and marked alveolar-arterial oxygen difference. Radiographically, a diffuse pattern of alveolar, interstitial, and peribronchial densities was observed in the lungs. Most dogs developed pneumomediastinum and gastroesophageal intussusception in the terminal phase of the disease. There was no response to treatment with antibiotics, corticosteroids, diuretics, or oxygen. At necropsy, the lungs were wet, heavy, and relatively airless. Absence of 1 kidney in 2 dogs and severe internal hydrocephalus in 2 dogs were additional necropsy findings. Pulmonary histopathology included metaplasia and atypia of the alveolar and bronchiolar epithelium, a nonpurulent inflammatory reaction characterized mainly by mononuclear cells and macrophages, eosinophilic hyaline membrane formation, and focal pulmonary fibrosis. The histological manifestations were typical of acute lung injury. Clinically, the findings were consistent with adult respiratory distress syndrome (ARDS), except for the relatively long course. No known risk factors for ARDS, such as trauma, toxin exposure, infection, or endotoxemia could be identified. The relationship of the other abnormalities (ie, renal aplasia, hydrocephalus) to the pulmonary disease also remains obscure. An inherited defect is suspected, because segregation analysis of the 4 litters suggests autosomal recessive inheritance.

Pulmonary alveolar microlithiasis (PAM) is a rare disease characterized by widespread localization of calcispherites in the alveolar spaces. The patients are symptomless for a long time. Nevertheless, this disease slowly develops into pulmonary fibrosis and cardiac failure. The chest X-rays and high-resolution computed tomography strongly point towards a diagnosis of PAM. As for therapeutic approaches, repeated broncho-alveolar lavages (BAL) have been performed with improvement of symptoms but without recovery, and a new oral drug treatment is still under way. We report 2 familial cases of PAM. Both patients underwent chest X-ray examination showing diffuse bilateral micronodular opacities of calcific density. After 5 years, in May 1993, one of them developed exertional dyspnoea, cyanosis, dry cough and was admitted to our Division. Cardiokinetic and diuretic drugs as well as oxygen were administered with satisfactory results. Then repeated BAL were performed. The chest X-ray after 6 months of sodium etidronate (300 mg t.i.d.) administration was unchanged.

A 40-year-old woman had complained of cyanosis induced by cold exposure from the age of 26. When she was 32 years old, Raynaud's phenomenon occurred. She developed diffuse cutaneous sclerosis affecting the upper limbs, face and trunk, digital pitting scar, flexion contractures of hands, dilatation of lower esophagus and pulmonary fibrosis, and she was diagnosed as scleroderma. Laboratory findings revealed positive anti-topoisomerase I antibody and hypergammaglobulinemia (IgG 2,782, IgA 632, IgM 146 mg/dl). However, serum complement levels were normal and anti-DNA antibodies measured by radioimmunoassay (RIA) were negative. Initial dose of oral prednisolone was 30 mg/day and afterwards 5 mg/day of prednisolone was maintained. At the age of 36, scleroderma and contraction of hands were progressed, and telangiectasias appeared on her chest at the age of 36. Laboratory tests revealed hypocomplementemia (C3 27, C4 9 mg/dl, CH50 16 U/ml) and high titers, more than 100 U/ml, of anti-DNA antibodies measured by RIA. Clinical evidence suggestive of SLE could not be found. Reexamination of previous sera by enzyme immunoassay, in which anti-DNA antibody could not be detected by RIA, clarified the presence of IgG anti-dsDNA antibodies. It was considered that there existed low avidity/affinity of anti-dsDNA antibodies at first, and afterwards high avidity/affinity of anti-dsDNA antibodies appeared. Increasing of oral prednisolone up to 30 mg/day normalized serum complements and decreased titers of anti-DNA antibodies. She had not developed any clinical evidence that suspected SLE throughout the course.

Tropical pulmonary eosinophilia (TPE) is considered to be a variant of human filarial infection. The pulmonary manifestations of TPE have been well described. Extra-pulmonary features of the disease, although not commonly seen, have been reported previously. A 9-year-old Malay girl with a history of recurrent cough and wheezing was admitted because of cardiac failure. Physical examination revealed a very sick girl with tachypnoea, central cyanosis, finger clubbing, elevated jugular venous pulse, generalized crackles and rhonchi in the chest, a loud second heart sound and hepatosplenomegaly. A chest radiograph showed cardiomegaly and right pleural effusion. Laboratory investigations revealed hypochromic, microcytic anaemia with persistent blood eosinophilia (absolute eosinophil counts varied from 1.9 to 5.5 x 10(9)/1). The ELISA test for antifilarial IgG antibodies was strongly positive. She responded promptly to treatment with diethylcarbamazine. In summary, this is a patient with TPE who presented with cor pulmonale, probably due to late-stage interstitial pulmonary fibrosis. In order to prevent the long term morbidity of cardiorespiratory disability, the early signs of TPE should be recognized and the infection treated.

At least 31 cases of familial fibrocystic pulmonary dysplasia, within 10 families, have been described in the world literature. The mode of genetic transmission of this disease, however, has been uncertain until now. The author observed three unequivocal and five probable cases of familial fibrocystic pulmonary dysplasia among 56 members of one family. Diagnostic criteria included progressive dyspnea and cyanosis, digital clubbing, pulmonary hypertension, negative sweat tests, polycythemia, arterial hypoxia and hypocapnia, chest radiographs showing diffuse bilateral pulmonary fibrosis, and diffuse fibrocystic pulmonary dysplasia at postmortem examination (two cases). Among the three unequivocal cases one father-to-son transmission was observed. Non-sex-linked dominant transmission of familial fibrocystic pulmonary dysplasia is thereby proved for the first time. One patient also developed a bronchial carcinoma in addition to fibrocystic pulmonary dysplasia; this is considered to be a cause-and-effect relationship and not a coincidental complication.

We describe the case of a 61-year-old male patient, in which the search for the cause of chronic respiratory failure, severe pulmonary hypertension and secondary erythrocytosis resulted in a diagnosis of combined pulmonary fibrosis and emphysema (CPFE). This is a unique, recently characterised syndrome with upper-lobe emphysema and pulmonary fibrosis of the lower lungs. The cause is unknown, but one of the main risk factor remains smoking. The patient was a heavy smoker (over 40 pack-years). He complained of dyspnoea on exertion and cough. Physical examination revealed basal crackles and cyanosis. The patient had severe reduction in diffusing capacity, out of proportion to his lung volumes (DLCO 27% of predicted value, FEV1 2.95 l (100%), FVC 4.41 l (118%), FEV1/FVC (66%). The blood gas showed hypoxemia (pO2 37 mm Hg), hypocapnia and respiratory alkalosis. Diagnosis was based on chest computer tomography, which revealed upper lobe emphysema and lower lobe ground glass changes and honeycombing. Severe pulmonary hypertension (SPAP 80 mm Hg) was confirmed by echocardiography and right cardiac catherisation. The patient received long-term oxygen therapy, inhaled corticosteroid and Ca-blocker.

This paper presents a case of a young patient with cyanosis and digital clubbing, until then an active, sporty person. He sought medical assistance due to the growing dyspnoea and the drop of effort tolerance. Initially the diagnostic process focused on the confirmation of the suspicion of pulmonary fibrosis or another interstitial lung disease as causes of the respiratory failure. Due to the atypical presentation of the symptoms, reaching the final diagnosis of digestive system disease with lung involvement required a more thorough multifaceted diagnostics of a number of systems and organs.
