According to cell cycle synchrony principles, bleomycin was infused for 48 hours, followed by a dose of either methotrexate or hydroxyurea after a 24-hour rest, in 36 adult patients with disseminated carcinoma. In this preliminary study, a 59% response rate was noted among patients with epidermoid carcinoma of the head and neck. Four of four patients with transitional cell carcinoma of bladder and one patient with hypernephroma also responded. No responses were noted among five patients with epidermoid carcinoma of the lung. The length of response ranged from 1 to 8 months (median, 2 months). Seventy-seven percent of the responders had extensive prior radiotherapy. The first patient treated had fatal sepsis with leukopenia, which prompted a widening of the treatment interval. Subsequently, toxicity was mainly mild or absent, the moderate or severe toxicity was primarily neutropenia, which was reversible. The use of low-dose bleomycin infusion is safe and may play a role in cancer therapy in combination with other agents specific for certain tumors. The length of infusion should be determined by the cell cycle of the tumor, if its potential synchronizing capabilities are to be exploited.

Thirty-nine patients with advanced epidermoid carcinoma of the head and neck were treated with a combination of cis-dichlorodiammineplatinum(II), methotrexate, bleomycin, and vincristine. Twenty-nine patients were evaluable for response and 39 were evaluable for toxicity. With this regimen toxicity was acceptable and the following rates were observed in a total of 139 treatment courses: 100% (nausea and vomiting), 3% (decreased creatinine clearance), 4% (thrombocytopenia), 5% (leukopenia), and 2% (pulmonary fibrosis). There was one death due to sepsis during a period of chemotherapy-induced leukopenia. Although the patients treated with this regimen had advanced disease and had been treated aggressively previously, an overall response rate of 24% was observed, with three patients (10%) having a complete response. Median duration of response was 7 + months. These results indicate that this intensive combination chemotherapy has a sufficiently favorable risk/benefit ratio to allow its evaluation in randomized clinical trials in patients with head and neck cancer.

Investigated were a total of 30 cattle 6 of which had experimental surgery infection and 24 showed spontaneously developing suppurative infection. The animals were studied in terms of general status, blood picture, quality of urine and synovia, and rumen content. The dynamis was followed up of the development of sepsis and purulent artritis. It was found that in case of suppurative surgical infections in cattle the general status was invariably affected, the severity of the process depending on its localization and developmental phase. Changes were observed also in the eye fundus and in the urinary and the digestive system. There were anemia and leukopenia which alternated with leukocytosis, and transient changes in the values of the erythrocyte sedimentation rate and the blood electrolytes. The SGOT values almost constantly increased, and the hemoculture was not positive in all cases.

Consecutive newborn autopsy cases were divided into infected and noninfected groups on the basis of pathologic findings and cultures, and were compared to a concomitant consecutive group of neonatal survivors with proven bacterial sepsis. Newborns dying with bacterial infection often demonstrated leukopenia, neutropenia, and thrombocytopenia, usually associated with normal bone marrow cell production. Those with nonfatal sepsis frequently had neutrophilia with an increase in absolute band counts. Of infected newborns 80% showed one or more hematologic abnormalities as did 43% of newborns dying without bacterial infection. Of newborns dying with bacterial infection 13% had no hematologic abnormality. Blood cultures were negative in 18% (seven) of the infants dying with bacterial infection. Abnormalities of the white blood cell, differential and platelet counts are not invariably specific for bacterial infection nor do normal values adequately exclude it. Blood cultures may be negative in newborns dying with significant foci of bacterial infection.

Respiratory distress is the most frequent symptom initiating referral to neonatal intensive care centers. Previous reports have indicated that 40% of infants with sepsis proved by blood culture had respiratory symptoms as their clinical presentation. In this prospective study there were 145 consecutive infants referred because of respiratory distress. Two-site blood cultures were collated with all other clinical and laboratory data to confirm a diagnosis of septicemia. There was a 4.8% incidence of bacteremia, and clinical and laboratory parameters confirmed septicemia in 3.5% of infants studied. Sixty percent of these infants had group B streptococcal sepsis, and 80% had leukopenia. The low incidence of confirmed septicemia in infants referred because of respiratory distress suggests that antibiotic therapy should not be routine.

A cluster of three cases of staphylococcal septic endarteritis originating from percutaneously inserted brachial artery catheters for regional cancer chemotherapy prompted an epidemiologic and clinical study of bacteremic infections associated with this therapeutic modality. Nine cases were identified over a 3 1/2-year period (1.6% of all catheterizations), all caused by Staphylococcus aureus. The cluster followed discontinuation of hexachlorophene for scrub of the extremity prior to cannulation; phage-typing suggested the three cases were caused by the patients' own strains of Staphylococcus. These infections produced a distinctive clinical syndrome which facilitates implicating the catheter in the genesis of fever occurring in a patient receiving intra-arterial chemotherapy: early localized pain (89%) and hemorrhage (78%), and Osler's nodes distally (44%), later followed by local inflammation (78%), purulence (56%) and signs of systemic sepsis (100%) (each factor, p less than or equal to .005). Duration of cannulation did not influence susceptibility to infection. However, difficult cannulations or need for repositioning the catheter (p = .0096), prior radiation therapy (p = .033), leukopenia (p less than .05) and hypoalbuminemia (p less than .05) were all associated with septicemia. In the 25 months since implementation of specific control measures, there have been no further catheter-related septicemia in 310 catheterization (p less than .001). Guide-lines for prevention and management of these infections are provided.

Vindesine, a new vinca alkaloid, has shown therapeutic activity in several human malignancies. A phase II study in 26 patients with squamous cell carcinoma of the esophagus was performed. Sixty percent of these patients had received prior chemotherapy. The starting dose was 3.0 mg/m2, which was escalated by 0.5 mg/m2 to a maximum of 4.5 mg/m2. Treatment was given once weekly for 7 weeks and every other week thereafter. Twenty-three patients were evaluable for response and toxicity. One complete remission (3 months), three partial remissions (5, 4, and 2+ months), and two minor responses (1.5 and 1 month) were seen. The major toxic effects were peripheral neuropathy, leukopenia, fever and myalgias, and alopecia. There was one drug-related death from leukopenia and sepsis. Vindesine has demonstrated therapeutic activity in esophageal carcinoma. Further studies with this agent are indicated.

Twenty patients with several histologic subtypes of non-Hodgkin lymphoma who had become resistant to combination chemotherapy were treated with a five-day course of the epipodophyllotixin VP-16. Of 19 evaluable patients, 8 (42%) responded to treatment with 1 complete response and 7 partial responses. The median duration of response was 5.5 months. Seven of the responders had a diffuse lymphoma and 1 had a nodular lymphoma. Of the responders who had diffuse histiocytic lymphoma (DHL), diffuse mixed lymphoma (DML), and diffuse undifferentiated lymphoma (DUL)--the more aggressive histologies in the Rappaport classification--6 of 13 (46%) evaluable patients responded to therapy. Responses were seen in node-dominant, skin-dominant, and marrow-dominant disease. Toxicity was mainly hematopoietic, 53% of patients experiencing leukopenia ( less than 2,000 cells per cu mm) and 68% of patients experiencing thrombocytopenian 2,000 cells per cu mm) and 68% of patients experiencing thrombocytopenia ( less than 100,000 platelets per cu mm). There were two deaths attributable to profound leukopenia with sepsis. The activity of VP-16 in patients who have previously been extensively treated with multiple drugs including vincristine supports its activity in the lymphomas and suggests its lack of cross-resistance with vincristine. The inclusion of VP-16 in primary treatment protocols in the diffuse lymphomas should be considered.

Of 237 cases of gram-negative rod bacteremia observed at the UCLA Medical Center during a 12 month period, 52 (22 per cent) occurred while the patient was receiving antibiotics which inhibited the infecting organism by disc diffusion tests. One half of the plasma samples available from 42 such patients with "breakthrough" bacteremia had subinhibitory circulating antibiotic levels when cultures were positive. Sepsis documented within 72 hours of initiation of therapy was usually due to antibiotic-sensitive Esch. coli and was associated with inadequate antibiotic levels; the patient was usually treated with a penicillin or cephalosporin. The source of bacteremia was most frequently the urinary tract or the biliary tree. In contrast, sepsis occurring more than 72 hours after the administration of antibiotics was frequently caused by multiple antibiotic-resistant Esch. coli in patients treated with gentamicin in adequate dosage and was associated with leukopenia or undrained purulent collections. Therapy ultimately failed in 20 cases (48 per cent): in early "breakthrough" bacteremia, failure was associated with subinhibitory antibiotic levels, and in late "breakthrough" bacteremias with inadequate drainage or impaired host defenses.

Bone marrow toxicity occurred in 4 of 15 patients treated with 5-fluorocytosine (5-FC) for serious fungal infections. The development of marrow toxicity appeared to be related to serum 5-FC levels of 125 mug/ml or greater. In three patients, accumulation of toxic levels of 5-FC was related to diminished renal function. One patient with acute renal failure and prolonged high levels of 5-FC developed marrow aplasia and died of bacterial sepsis. Three patients experienced leukopenia, which was readily reversed when the dosage of 5-FC was decreased and the serum concentration was lowered. With careful monitoring of serum 5-FC concentration and renal function, the dose-related toxic effects of 5-FC on the marrow can be avoided.
