Intravenous cefazolin and cefoxitin were compared in a prospective randomized trial in infections where the suspected pathogen was expected to be susceptible to both antibiotics. In the cefazolin group (12 patients) the diagnosis was pneumonia in 4, including 2 with pneumococcal bacteremia, soft tissue infection in 5, Staphylococcus aureus bacteremia in 1, acute pyelonephritis in 1, and disseminated gonococcal infection in 1. In the cefoxitin group (10 patients) the diagnosis was pneumonia in 4, including 2 with pneumococcal bacteremia, soft tissue infection in 4, acute pyelonephritis in 1, and disseminated gonococcal infection in 1. In the cefazolin group receiving an evaluable course of therapy, a good clinical response was seen in 10 of 11 patients, and a bacteriological response was seen in 5 of 7. Cefazolin failed to eradicate S. aureus bacteremia in 1 patient and S. aureus in a skin ulcer of another patient. All 10 cefoxitin patients had good clinical and bacteriological responses, but in 1 patient S. aureus colonization of a postoperative wound recurred after discontinuation of the drug. Side effects in both groups included skin rash, phlebitis, and elevation of the serum alkaline phosphatase. Both cefoxitin and cefazolin appeared effective in infections caused by susceptible aerobic pathogens with the possible exception of S. aureus, although all 11 strains of S. aureus isolated in this study were susceptible in vitro to both antibiotics. Cefoxitin appeared to be equivalent to cefazolin in efficacy and occurrence of side effects.

The efficacy and safety of cefamandole nafate and penicillin G procaine suspension were compared in the treatment of pneumococcal pneumonia in hospitalized adults. One hundred thirteen patients with clinical and radiographic evidence of pneumococcal pneumonia were randomly assigned to receive 600,000 units of procaine penicillin intramuscularly every 12 hr or 500 mg of cefamandole intramuscularly every 6 hr. The two groups were comparable with regard to patient type and extent and severity of pneumonia. Alcohol abuse was a host factor in 31% of all patients in the trial. All strains of Streptococcus pneumoniae isolated were inhibited by less than or equal to 1.6 microgram of cefamandole/ml. Of 58 patients treated with cefamandole, 50 had a satisfactory response, as did 46 of the 55 patients treated with penicillin. Results of tests of liver function were abnormal (primarily, elevated levels of transaminase or alkaline phosphatase) in 38% of the entire group of patients and occurred with equal frequency in patients receiving cefamandole or penicillin. Side effects during therapy, including superinfection, occurred equally with either drug. In a random trial, cefamandole was as effective and safe as penicillin in the treatment of pneumococcal pneumonia in adults.

Twenty-six cases of miliary tuberculosis were studied in retrospect. The mean age of the patients was 62 years. Eighteen patients suffered from another underlying chronic disease. Nine had been treated with corticosteroids or cytotoxic agents. A limited manifestation of tuberculosis had been previously verified or suspected in ten cases. Fever was present in 85% of the patients, frequently combined with fatigue or abdominal pain. Serum alkaline phosphatase was elevated in 81% of the cases. Minor haematological abnormalities (anaemia, etc.) were found in 16 cases and pancytopenia, stimulated lymphocytes or chronic myeloid leucaemia in six. Miliary mottling was found in the chest radiographs of 13 patients. Other findings were pleural effusion, mediastinal node enlargement, opacities suggesting pneumonia or old, possibly tuberculous lesions. Antituberculosis therapy was initiated in 12 patients, two of whom died within a few days. There was a high frequency of liver or system involvements. It is concluded that laparoscopy or liver needle biopsy are valuable diagnostic procedures in patients with fever and elevated alkaline phosphatases of unknown aetiology. A therapeutic test with antituberculous drugs should be undertaken in suspected cases.

Reccurrent abnormalities of polymorphonuclear leukocyte and monocyte bactericidal activity were demonstrated in a patient with sarcoidosis. Defective function occurred during hypercalcemia complicating recovery from Listeria meningitis, and during separate, unrelated episodes of erythema nodosum, staphylococcal cellulitis, and pneumococcal pneumonia. Leukocyte morphology, oxidative metabolism, degranulation, and content of myeloperoxidase and lysozyme were normal, but low leukocyte alkaline phosphatase activity was demonstrable on one occasion. Despite defective bactericidal function of monocytes, the patient's macrophages killed bacteria normally. The relationship between an intermittent leukocyte bactericidal defect and sarcoidosis is unclear; however, further studies of leukocyte function in sarcoidosis patients with opportunistic infection are indicated.

This experiment was designed to compare 3 dose levels of aflatoxin B1 (0.0, 0.5, and 1.0 mg/kg of body weight) and 2 infection levels of Fasciola hepatica metacercariae (0 and 220) to determine whether an additive effect from aflatoxin B1 occurs when fascioliasis is present in dairy calves. Twenty-four male, Holstein calves, 4 weeks old, and averaging 45.8 kg each, were assigned at random to 6 treatment groups, 4 calves per group: group 1--negative control; group 2--0.5 mg of aflatoxin B1/kg; group 3--1.0 mg of aflatoxin B1/kg group 4--220 metacercariae; group 5--220 metacercariae plus 0.5 mg of aflatoxin B1/kg; and group 6-220 metacercariae plus 1.0 mg of aflatoxin B1/kg. The single oral dose of 220 metacercariae was given (groups 4, 5, and 6) at the start of the 10-week experiment, and 5 weeks later, the single oral dose of aflatoxin B1 was given (groups 2, 3, 5, 6). Results from the principals, as compared with that from the controls (group 1), included significant decreases of dry matter intake (P less than 0.006), body weight (P less than 0.024), and serum albumin (P less than 0.04), and in groups 4, 5, and 6 infected with 220 flukes, there were significantly increased values of prothrombin time (P less than 0.014), serum alkaline phosphatase (P less than 0.04), and serum sorbitol dehydrogenase (P less than 0.007). Significant differences in number of flukes recovered from liver were seen in groups 4 to 6 given 0, 0.5, and 1.0 mg of aflatoxin B1/kg (P less than 0.046). The single oral dose of 22* fluke metacercariae in groups 4, 5, and 6 resulted in significantly increased concentrations of serum total protein (P less than 0.003) and globulins (P less than 0.01). Results from the development of the flukes from metacercariae to the mature state with sizes, numbers, feeding habits, and pathologic lesions were described. Differences in numbers of flukes recovered from liver of groups 4 to 6 and the presence of pneumonia in calves of group 6 indicated aflatoxin B1 produced persisting, lowered resistance. In all animals necropsied, the liver was the organ most affected by aflatoxin B1 as well as with flukes. Periportal fibrosis, monocytic infiltration, fatty infiltration, and bile duct proliferation were the usual lesions induced by aflatoxin B1. Additive toxic effects were observed in the groups 5 and 6 dosed with flukes and aflatoxin B1, with significant variations of serum and plasma values, as well as increased severity of histopathologic changes.

When a patient with sickle cell disease has fever and a lung infiltrate, usually it will be due to infection, even though cultures may be negative. However, pulmonary infarction can be virtually indistinguishable from pneumonia. Pneumonia is likely to be present in those younger than five years, with purulent sputum and upper lobe infiltrates. Coexisting crisis, a normal or low leukocyte alkaline phosphatase score and microangiopathic changes on peripheral blood smear favor thromboembolic disease. The fat embolism syndrome, caused by bone marrow necrosis and infarction, occurs in sickle cell disease.

The efficacy and tolerance of clarithromycin (250 mg twice daily) were compared with those of roxithromycin (150 mg twice daily) in an open, multicentre trial of 77 inpatients with community-acquired pneumonia. Sixty-five patients were clinically evaluable (34, clarithromycin; 31 roxithromycin). Efficacy was comparable between treatment groups: 26 of 34 patients (76%) treated with clarithromycin were clinically cured, including four with atypical pneumonia. In the roxithromycin group 25 of 31 patients (81%) were clinically cured and one was improved. Cough, appearance of sputum, and fever improved in most patients in both treatment groups. Chest X-rays after treatment showed resolution or improvement in 76% of patients who received clarithromycin and 87% of those who received roxithromycin. The clinical evaluation of the response generally agreed with the bacteriological response. Among patients who were bacteriologically evaluable for four target organisms (Streptococcus pneumoniae, Haemophilus influenzae, H. parainfluenzae, and Branhamella catarrhalis) the pathogen was eradicated in four of seven (57%) in the clarithromycin-treated group and in five of six (83%) in the roxithromycin-treated group. Adverse events were reported in more patients who received roxithromycin (21.6%) than in those who received clarithromycin (12.5%) although the incidences were not statistically significantly different. The majority of adverse events were transient increases in serum alanine aminotransferase, serum aspartate aminotransferase, and alkaline phosphatase. Clarithromycin was shown to be effective and well-tolerated; the clinical efficacy and safety of clarithromycin and roxithromycin were comparable.

In a prospective study of community-acquired pneumonias, 30 patients were diagnosed with Legionnaires' disease in 15 months. Clinical, laboratory and radiologic features of these patients are reviewed and compared with those who have pneumococcal pneumonia. Alcoholism, history of smoking, previous antimicrobial therapy, gastrointestinal and neurologic manifestations, elevations of serum transaminases, alkaline phosphatase and creatinine levels were more frequent in pneumonia due to Legionella pneumophila than in pneumococcal pneumonia. The presence of respiratory failure and radiologic progression were common findings that suggested L pneumophila as the etiologic agent of a community-acquired pneumonia. Development of respiratory failure was associated with involvement of several lobes and isolation of L pneumophila in any specimen. In 21 of 30 patients with Legionnaires' disease, L pneumophila was isolated from respiratory specimens. Overall mortality was 10 percent, but it increased to 27 percent in patients not treated with erythromycin initially.

Ten goats were inoculated with peste des petits ruminants virus, a paramyxovirus closely related to rinderpest virus. All goats developed severe clinical disease, 8/10 having coughing or dyspnea as prominent clinical signs. In addition, all of the goats had stomatitis and diarrhea. Histopathologic and immunohistochemical studies were done only on the respiratory tracts. Pathologic changes ranged from mild multifocal bronchiolitis and bronchitis to severe bronchointerstitial pneumonia. Lesions were more severe in anteroventral than caudal lobes. The histologic nature of the viral process in the goat lungs had many features in common with the processes of pneumonia in dogs, due to canine distemper, or pneumonia in human beings, due to measles virus. Immunohistochemical staining of formalin-fixed, paraffin-embedded respiratory tract tissue was performed using an indirect system with rabbit anti-rinderpest virus serum, biotinylated anti-rabbit antibody, streptavidin-alkaline phosphatase, and nitroblue tetrazolium chromogen. Staining was sensitive, highlighting the presence of viral antigen in both lung and trachea of all goats. Viral antigen was found in both cytoplasm and nucleus of tracheal, bronchial, and bronchiolar epithelial cells, type II pneumocytes, syncytial cells, and alveolar macrophages. In general, the amount of staining correlated directly with the severity of the inflammatory process.

This report described seventeen patients suffering from fulminant hepatitis and had a rapid fatal course. They were all residents of Southern Thailand. Fourteen cases were recognized between April and August which is the beginning of the rainy season in this part of the country. All age groups were found with males slightly predominant. Clinical manifestation presented with fever and later developed jaundice, convulsion and other central nervous system symptoms, liver failure and acute renal failure. Four cases had pneumonia and another three cases had pleural effusion. Laboratory investigations revealed hyperbilirubinemia, marked increase in serum transaminases, a variable alkaline phosphatase level and electrolytes derangement. HBsAg was positive in only two of fourteen cases. Blood cultures and serological examination for infections were unfruitful. Histopathological changes of the liver were classified into three types; type 1 massive hepatocellular coagulation necrosis; type 2 massive scattered hepatocellular necrosis and type 3 massive bridging hepatocellular necrosis. Electron microscopy of five cases revealed spherical viral-like particles ranging in size 70 to 90 nm in diameter, in the cytoplasm of liver cells. This is believed to be a unique type of fulminant hepatitis, possibly viral in origin, and were clinically and pathologically different from the previously described fulminant viral hepatitis.
