A 20-year-old man who looked after a pack of hounds was admitted with a short history of headache, fever, haemoptysis and muscle cramps. Investigations showed type I respiratory failure with diffuse pneumonitis, pyogenic meningitis and raised liver enzymes. Leptospirosis was suspected and treated with the appropriate antibiotics leading to a full recovery. The diagnosis was confirmed by a titre of I/2560 to Leptospira icterohaemorrhagiae. The case illustrates an unusual presentation of this infection and argues for early antibiotic treatment.

Cystic fibrosis, an autosomal recessive disorder, is the most common genetic disease of Caucasians. One in 25 Caucasians are carriers of the gene. The gene is found far less commonly in other races. There are over 230 different alleles of the gene, located on the 7th chromosome. The gene encodes for a membrane protein that functions as an ion channel. The survival of cystic fibrosis patients has been gradually increasing, with a mean survival in 1990 of 28 years. If the current trend of improved survival continues, it is estimated that half of cystic fibrosis patients will be over 18 years old by 1996. Disease is found in many organs including the lungs, sinuses, pancreas, gastrointestinal tract, hepatobiliary system, sweat glands and reproductive tract. The majority of patients die of pulmonary disease. The airways become chronically colonized with bacteria that cannot be eradicated, leading to bronchitis, bronchiectasis, and finally, pulmonary fibrosis with respiratory failure. The pulmonary disease may be complicated by massive hemoptysis and pneumothorax. Patient survival rates have increased because of antibiotic therapy and improved nutrition with pancreatic enzyme replacements. New treatments for the pulmonary disease are under clinical trial and include antiproteases, amiloride, a sodium channel blocker, and DNase. The insertion of the normal cystic fibrosis allele into an animal model using a modified adenovirus with effective transcription suggests that gene therapy may be possible in the future, but safety and technical problems have to be addressed.

Seventy one patients with active pulmonary tuberculosis who died during the past 5 years (1989 to 1993) were evaluated on their causes of death. Twenty two patients (31%) died directly of tuberculosis, and among them, 18 patients (81%) of 22 patients who died of tuberculosis) had very advanced tuberculosis. The majority of them (64%) were old age over 70 years and were bedridden due mostly to cerebrovascular injuries. The serum level of albumin was low in all 17 patients in whom it was measured. Establishment of diagnosis of tuberculosis was delayed over one month after the onset of symptoms in 59% of patients who died of severe disease. Sixty one percent (11/18) of patients died within the first month after the initiation of chemotherapy and about 90% (16/18) died within 3 months. Two patients died from massive hemoptysis and other patients died of either respiratory failure or tuberculosis meningitis. From these observations it was found that very advanced tuberculosis was the major cause of death in patients who died of tuberculosis and that the advanced disease was chiefly caused by the delay on the establishment of diagnosis, and it was most important to detect tuberculosis as early as possible, with regular check up of chest X-ray and frequent examination for AFB (acid-fast bacilli) for tuberculosis suspected patients. On the other hand, the majority of patients (49/71) died of complicating medical problem unrelated to tuberculosis. Seventeen patients died from malignancy (seven lung cancer, four lymphoma, two laryngeal cancer, etc). Ten deaths were the result of bacterial superinfection. Other patients died from respiratory failure due to COPD, arteiosclerotic heart disease, or cerebrovascular injuries, etc. Two patients of old age died of hepatic failure possibly caused by adverse reaction of TB chemotherapy. It was found that diseases unrelated to tuberculosis were the cause of death in approximately 70% of patients with active tuberculosis, and it should be emphasized to detect early and to treat these diseases, in particular malignancy. And it is also imperative that the chemotherapy for TB must be instituted very carefully with frequent monitoring of liver function in patients with old age.

A 44-year-old woman with malignant T-cell lymphoma and secondary leukemia received an allogeneic bone marrow transplant (BMT). She had received BMT conditioning treatment with total body irradiation and chemotherapy. Hemoptysis and progressive dyspnea developed 11 days after the transplant. A chest roentgenogram showed bilateral diffuse infiltrates. Bronchoalveolar lavage fluid was bloody, and diffuse alveolar hemorrhage (DAH) was diagnosed. Respiratory failure progressed despite mechanical ventilation and administration of corticosteroids. The patient died 58 days after the transplant DAH after BMT has been recognized in western countries as a syndrome with high mortality. We draw attention to the fact that DAH is a serious early pulmonary complication of BMT also in Japan.

Bilateral, concurrent massive hemoptysis with respiratory failure is rare and difficult to manage. We encountered two patients with this condition. One was a 51-year-old woman and one was a 63-year-old woman. Both had inactive pulmonary tuberculosis and episodes of hemoptysis. Home oxygen therapy was prescribed to the former patient and bronchial artery embolization was done in the latter. The sites of initial bleeding were in the left basal segment and in the lingular segment. Bleeding was well controlled by endobronchial tamponade with a Fogarty balloon catheter in the left main bronchus, contralateral intubation, and systemic artery embolization. Use of water instead of air in the balloon was more effective in over the long term. Concurrent bleeding from the contralateral upper lobe bronchus was controlled by compression with a tracheal tube cuff at the bronchial orifice. Afterward, an infiltrative shadow was seen on the chest X-ray film and hemoptysis occurred in case 2 occurred in case 2. Treatment with erythromycin and antituberculosis drugs brought about improvement of chest X-ray findings and disappearance of the hemoptysis.

The surgical management of patients with nontuberculous Mycobacteriosis caused by Mycobacterium avium complex (MAC) was studied regarding the following cases: (1) We investigated whether there had been an appropriate time for surgical management of patients with MAC who had not responded to medication and who died after their conditions became worse retrospectively. During the past 10 years, 49 patients diagnosed with MAC died at the Toneyama national hospital. 26 patients of them died of respiratory failure, apparently due to the worsening of MAC. Excluding 2 patients who were extremely elderly, we investigated whether surgical management could have been applied in the remaining 24 patients. We found that surgical management would have been possible in only one patient, and that at the time of diagnosis of MAC in 23 patients, surgical management was already not possible. (2) There are patients with MAC who do not respond to medication and who continue to excrete bacilli, chest X-ray findings gradually become worse for several years. In 1989 we retrospectively studied chest X-ray findings from MAC patients and found that 36 out of 103 patients (35%) showed worsening chest X-ray findings. The strains were identified in 44 of the 103 patients by the DNA probes method. However, of 37 patients with M.avium (41%), 15 had worsening of chest X-ray findings, while none out of 7 patients with M. intracellulare had worsening of chest X-ray findings. We then observed the clinical course of 37 patients who showed continuous excretion of bacilli and whose serotypes had been identified (20 with serovars 4, 1 with serovars 6, 6 with serovars 8, 2 with serovars 12, 4 with serovars 14 and 5 with serovars 16) by using the fast-atom bombardment mass spectrometry (FAB/MS). Chest X-ray findings later worsened in 14 (70%) of 20 patients with serovars 4. Nine of these patients have since died; excluding one patient who had liver cancer, eight died of respiratory failure due to worsening of MAC. In 17 patients with serotypes except serovars 4, 4 (24%) patients had worsening of chest X-ray findings, but none of the 5 deaths in this group were due to respiratory failure owing to worsening of MAC. These results suggest that it is difficult to establish the indication of surgical management in MAC patients, except for patients with repeated hemoptysis at present. The prognosis and surgical management of pulmonary disease caused by M. avium complex should be considered.

A newborn boy with obstructive apnea secondary to glossoptosis was treated by securing his tongue to his lower lip. Soon after, the button that served for posterior fixation became detached and was thought to have been evacuated via the digestive tract. Twenty-two months later the infant presented with pneumonia involving the right lower lobe and hemoptysis, causing an acute respiratory distress syndrome (ARDS). After mechanical ventilation was started marked gastric distention was observed. Esophagography and bronchography revealed a fistula between the right main stem bronchus and the esophagus. During surgical repair the plastic fixation button was found in the bronchial orifice of the fistula. Despite surgical correction of the fistula the child died of refractory respiratory failure.

The objective of this study was to identify the prognostic factors influencing the outcome of aspergillosis in two models of immunodeficiency, namely haematological malignancies and HIV infection. The study is based on a 5 year prospective logistic regression analysis of risk factors, clinical features, radiological findings and therapy affecting the prognosis of aspergillosis in 43 patients, i.e. 27 haematological neoplastic patients (group A) and 16 HIV infected patients (group B). Univariate analysis indicated that neutropenia (P = 0.02), haemoptysis (P = 0.03) and concomitant AIDS (P = 0.02), negatively influenced the prognosis of aspergillosis. Comparing the two groups of patients, significant differences emerged in the prognostic indicators. In particular respiratory failure (P = 0.02) and radiological bilateral involvement of the lungs were associated with a poor prognosis in group A (P = 0.04) and low (2100/mm3) T CD4+ cell count in group B (P = 0.02). At variance, a better prognosis was documented in patients treated with sequential therapy (amphotericin B and itraconazole) only within the group of haematological patients (P = 0.003). On multivariate analysis sequential therapy (P = 0.01) and AIDS (P = 0.03) were independent prognostic indicators of aspergillosis. In conclusion, our prospective study indicates that aspergillosis, although an uncommon event in patients with HIV infection, has a more severe prognosis in comparison to haematological patients. Future prospective clinical trials are necessary to confirm the real importance of the sequential therapy, with amphotericin B and itraconazole, in patients with aspergillosis.

Bronchiectasis is pathologically defined as an abnormal and permanent dilatation of one or several bronchi. There are localized and generalized types of bronchiectasis. A vicious circle hypothesis, including an initial insult to the lower airways, impaired mucociliary clearance, microbial colonization/infection, bronchial obstruction and a local inflammatory response, has been proposed to explain the damage to the bronchial tree and the adjacent lung parenchyma. The clinical picture is variable and affected individuals might be asymptomatic or suffer from severe respiratory failure. Daily sputum production is the most common, though unspecific symptom of bronchiectasis. Other common symptoms are hemoptysis and recurrent episodes of sputum purulence, fever and pleurisy. Occasionally, major, life-threatening hemoptysis from a ruptured bronchial artery occurs. Infectious complications, e.g. lung abscess, empyema, brain abscess, and secondary amyloidosis are rarely seen today. The chest radiograph reveals changes suggestive of bronchiectasis in the majority of patients with clinically important disease. High resolution computed tomography of the lung has almost completely replaced bronchography for diagnosis, the latter rarely being of value if surgery is contemplated. No etiology is identified in about one- to two-thirds of the patients, although there are many diseases eventually associated with bronchiectasis. Prevention and therapy of underlying diseases are most important. Traditionally, the therapy of symptomatic bronchiectasis is based on antibiotics, antibronchoobstructive medication, and chest physical therapy. Surgical resection is the treatment of choice for localized symptomatic disease. Bilateral lung transplantation should be considered in younger patients with severe, generalized bronchiectasis and respiratory failure. Prospective, randomized, largescale trials supporting any of the different treatment strategies are not available, but antibiotics and surgery probably have improved the long-term outcome of many patients with bronchiectasis. In this review, some recent findings regarding the classification, pathogenesis, pathology, etiology, diagnosis, treatment, and prognosis of bronchiectasis are discussed.
