Fatal measles (rubeola) pneumonia, confirmed by viral culture and electron microscopy, occurred in a previously healthy 19-year-old man. Autopsy disclosed measles pneumonia but no recognizable disease that would predispose to such an infection. However, the prolonged course of the measles infection and very low levels of serum antibodies to measles indicate that an immune deficient state existed. Nearly all other adults dying of measles pneumonia have had impairment of the immune system, typically due to a lymphatic or hematologic malignant neoplasm treated with chemotherapy. An immunodeficient state may be a precondition for death from measles pneumonia in adults. Enlargement of air spaces with fibrosis in the anterior portions of both lungs is suspected to be due to tissue necrosis and high mechanical ventilatory pressures.

One hundred and thirty-nine febrile episodes in 120 patients were treated with sisomicin after a combination of carbenicillin and a cephalosporin antibiotic had failed. These patients were randomized to receive sisomicin either by continuous or by intermittent infusion. The response rate for patients treated with sisomicin was 61 percent by continuous infusion and 46 percent by intermittent infusion, which was not statistically significant. Pneumonia, septicemia, and soft tissue infections were the most frequent infections. Most (96 percent) of the identified pathogens were gram-negative bacilli with the most frequent being Klebsiella pneumoniae, Escherichia coli, and Pseudomonas aeruginosa. The response rate was higher in those patients whose neutrophil count increased or remained the same while on therapy. The worst response was obtained if there was a decrease in the neutrophil count during therapy. The major toxicity of sisomicin was found to be azotemia and occurred in 17 percent of episodes treated by continuous infusion and in 21 percent treated by intermittent infusion. Hearing loss in the high frequency range occurred in five patients. Sisomicin is effective in the treatment of gram negative infections in neutropenic cancer patients.

Fungal infections are increasing in frequency, especially among patients with haematological malignancies. The fungi which cause most of the infections in cancer patients are Candida spp. and Aspergillus spp. These fungi seldom infect individuals with normal host defence mechanisms. Many factors predispose patients to fungal infection, including neutropenia, lymphopenia, gastro-intestinal ulceration, intravenous catheters and adrenal corticosteroid therapy. Candida spp. cause 5 major types of infection: dermatitis, thrush, gastro-intestinal, primary organ and disseminated infection. Aspergillus spp. and Phycomycetes cause pulmonary, disseminated or rhino-cerebral infection. Cryptococcus neoformans usually causes meningitis but may cause pneumonia or disseminated infection. The diagnosis of fungal infection is often made only at postmortem examination, because it is difficult to isolate the aetiological agent from sites of infection. Amphotericin B remains the mainstay of antifungal therapy, but is seldom effective in the patient with compromised host defences. Successful management of these infections in the future will depend upon improvement in diagnostic capabilities as well as the introduction of more effective and less toxic antifungal agents.

The majority of infectious complications in cancer patients are caused by Gram-negative bacilli. The most common organisms are Escherichia coli, Klebsiella spp. and Pseudomonas aeruginosa. Sites of infection are related to the patients' underlying malignancies, but pneumonia and septicaemia occur most often. Important newer antibiotics for the therapy of these infections are aminoglycosides and semisynthetic penicillins. It is advisable to utilize combinations of antibiotics for serious infections in cancer patients, and therapy should be instituted promptly at the onset of infection.

Because of inspiration into the tracheo-bronchial aireays, regurgitation from purely oesophageal diseases can provoke various respiratory affections: acute broncho-pulmonary blocking broncho-pneumonia, pulmonary suppuration, night cough, fits of nocturnal suffocation, chronic bronchitis sometimes hemoptic. A mega oesophagus, a diverticulum, stenosis or oesophagus cancer are at the origin. Oesophago-bronchial fistulae are excluded. The decrease of the glottal guarde remains to be explained because it usually protects the trachea from such mishaps (part played by decubitus, sleep, secretions stagnating in the pharynx).

Modern advances in the development of antimicrobial agents and in chemotherapy have made available potent aminoglycoside antibiotics, with more effective ones to come. Their effectiveness against P. aeruginosa is a great contribution to patients with cystic fibrosis and other chronic disorders. The development of carbenicillin has augmented the effectiveness of the aminoglycoside antibiotics. Ticarcillin is similar to carbenicillin and will play a similar role in antibiotic therapy. The cephalosporins serve as alternative agents principally for their antistaphylococcal activity. We are urgently in need of a potent antibiotic agent against P. aeruginosa that can be given by the oral route. The TMP-SMX combination is a potent chemotherapeutic agent that can be administered by the oral route. It is effective in the treatment of P. carinii pneumonia, which is very common owing to the extended survival of patients with leukemia and other malignancies or with allografts who are prone to develop infections with immunosuppressive therapy.

Seventy episodes of Staphylococcus aureus sepsis occurring over a nine-year period in pediatric cancer patients are reviewed. Prominent findings at the time of diagnosis included fever, granulocytopenia, and active malignancy. Probable or suspected sites of primary infection were present in 40 episodes (57%). Serious direct complications of staphylococcal sepsis included only three cases of pneumonia and one of myositis. However, second infections by other organisms developed in 16 episodes (24%), resulting in nine nonstaphylococcal infectious deaths during therapy. Endocarditis and osteomyelitis never occurred in this group of patients. The median duration of antistaphylococcal therapy was 15 days.

A patient developed the superior vena cava syndrome from Nocardia asteroides pneumonia with mediastinitis. Specific treatment was dangerously delayed because malignancy was primarily suspected, and nocardial infection was not initially considered. The correct diagnosis was eventually made by appropriate stains and culture of a lung aspirate. Specific therapy with sulfonamide resulted in a cure of the infection, disappearance of facial swelling, and a long-term state of clinical well-being. Active nocardial pneumonia with mediastinitis is a treatable cause of the superior vena cava syndrome and should be considered in the differential diagnosis.

One hundred ninety-one unselected fluid specimens submitted routinely for cytologic examination were assayed to determine whether the measurement of carcinoembryonic antigen (CEA) levels in pleural effusions is useful in detecting malignancy. The mean +/- SD CEA level of 103 benign effusions was 4.1 +/- 2.9 ng/ml. Only one benign effusion had a level greater than 12 ng/ml (18 ng/ml). Benign inflammatory effusions (pneumonia, empyema) had a higher mean CEA activity (6.2 +/- 3.4) than effusions caused by congestive heart failure (2.9 +/- 1.5) (p less than 0.001). Twenty-four (34%) of 70 malignant effusions had a CEA level greater than 12 ng/ml, and 28 (40%) were "positive" by cytologic study. Thirty-eight (54%) were detected by one or both methods. Ten malignant effusions were positive by CEA (greater than 12 ng/ml) alone. These data suggest that the determination of CEA activity levels, when used in conjunction with other clinical findings, may be useful in detecting malignant pleural effusions.

The combination of carbenicillin plus cefamandole was administered to 88 patients with cancer during 116 evaluable episodes of fever. The overall response rate to carbenicillin plus cefamandole for the 116 episodes was 57%. There were 60 documented infections, of which 60% responded to this combination of antibiotics. The response rate was only 43% in patients with pneumonia. The etiologic agent was identified during 38 infections, of which 74% responded to carbenicillin plus cefamandole. Responses occurred less frequently in patients with neutropenia than in those without neutropenia and less frequently in patients whose infection was caused by organisms resistant to both antibiotics than in those with infection caused by organisms sensitive to one or both of the drugs. No side effects could be attributed to the antibiotic regimen.
