Radical cystectomy for bladder cancer is an operation that presents a low mortality rate, which can still be reduced by a better patient selection, particularly with respect to patients presenting a high cardiac risk. Morbidity is still elevated but a better preparation of the patients against infection, hyperdiuresis during and after the operation and a nonperitonization of the anterior pelvis should reduce the frequency of abscesses, septicemia and pyelonephritis. It seems reasonable to propose this operation as a curative procedure for stage B and recurring stage A and as a palliative procedure for stages C and D.

Urinary infections, with a spectrum from covert bacteriuria to severe pyelonephritis, commonly complicate pregnancy. Serious infections follow untreated silent bacteriuria in a fourth of cases, and routine screening can be justified in high-risk populations, particularly those from lower socioeconomic strata. Despite an initial salutary response to a number of antimicrobial regimens, covert bacteriuria recurs in one-third of treated women whose risk of pyelonephritis remains at 25%. Acute cystitis may be unrelated to these other infections and responds readily to a number of regimens; however, single-dose therapy is not recommended since early pyelonephritis can be mistaken for uncomplicated cystitis. Pyelonephritis is the most common severe bacterial infection complicating pregnancy. These women are frequently quite ill, and hospitalization is recommended. Since 85% to 90% respond within 48 hours to intravenous fluids and antimicrobials, continued fever and evidence of sepsis after two or three days should prompt a search for underlying obstruction. Perhaps 20% of women with severe pyelonephritis develop complications that include septic shock syndrome or its presumed variants. These latter include renal dysfunction, haemolysis and thrombocytopaenia, and pulmonary capillary injury. In most of these women, continued fluid and antimicrobial therapy result in a salutary outcome, but there is occasional maternal mortality.

One hundred and four children who were hospitalized for documented or suspected non-CNS bacterial infections (56 males/48 females, 22 days to 15 years old) were treated with intravenous imipenem/cilastatin for 9.4 days (range 3 to 28 days). Children up to three years of age received 100 mg/kg/day and older children 60 mg/kg/day, administered in four divided doses. Bacterial pathogens were isolated before therapy in 85%. Diagnoses in the 74 evaluable patients included bronchopneumonia with or without empyema (20%), peritonitis complicating appendicitis (16%), skin/soft tissue abscesses (14%), septicemia (11%) and miscellaneous other infections (39%). Among evaluable patients, 95% were clinically cured or improved. One patients, a marasmic child with pneumonitis due to pseudomonas, died during therapy. One evaluable patient each with shigellosis, Klebsiella pneumoniae empyema and streptococcal pneumonia had bacteriologic eradication or suppression but, due partly to noninfectious complications, had no overall clinical improvement. Most bacterial isolates (101/108) were eradicated, including many gram-negative and gram-positive aerobes and anaerobes; three pathogens persisted (one Proteus mirabilis and one Salmonella typhi, one Staphylococcus aureus); and one Escherichia coli pyelonephritis recurred after therapy ended too early. Imipenem/cilastatin was well tolerated by 91% of children. Clinical adverse experiences (AEs), none serious except for the one death, occurred in 19%; 12% were judged possibly related to imipenem/cilastatin, but none probably or definitely related. No serious laboratory AEs occurred; the most common AEs were eosinophilia (11%), urine discoloration, and infusion site pain. Imipenem/cilastatin is well tolerated and has excellent clinical efficacy in a wide variety of pediatric infections.

A homosexual man, seropositive for human immunodeficiency virus, developed back and leg pain that evolved, over three weeks, into a T-10 anesthetic, areflexic paraplegia. Spinal fluid examination showed lymphocytosis, markedly elevated spinal fluid protein, and hypoglycorrhachia. A spinal cord biopsy specimen disclosed an intramedullary granuloma containing acid-fast bacilli. The patient was treated with antituberculous drugs and had no progression of neurologic deficit. He died, eight months after first becoming ill, of Klebsiella pyelonephritis and septicemia. Mycobacterial meningomyelitis is presently the only known acquired immunodeficiency syndrome-related myelopathy responsive to specific treatment.

Ceftriaxone treatment (50 to 80 mg/kg once daily) was given to 201 children between 1 month and 18 years of age. There were 201 serious bacterial infections, including epiglottitis, pneumonia, cellulitis, osteomyelitis, septic arthritis, pyelonephritis, sepsis, and meningitis. The common pathogens responsible for pediatric infections isolated from these patients included Haemophilus influenzae, Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, and Escherichia coli. The overall clinic cure rate was 94%. Ten patients were clinically improved but not cured. There were two clinical failures. Bacteriologic failure occurred in six patients. The overall bacteriologic cure rate was 97%. Twenty patients (10%) experienced adverse effects; none required discontinuation of therapy. The efficacy, safety, spectrum, and convenience of ceftriaxone monotherapy make this antimicrobial agent a candidate for the treatment of choice of selected serious pediatric infections.

Gentamicin is a commonly used antibiotic in the treatment of gram-negative infections including septicemia and pyelonephritis. Bacterial endotoxin is liberated during antibiotic therapy and may lead to endotoxemic shock. Steroids such as hydrocortisone are generally recommended in the treatment of endotoxemic shock. There are very limited data on the influence of endotoxin or corticosteroids on the pharmacology of antibiotics, especially aminoglycosides, which are nephrotoxic. We studied the influence of both Escherichia coli endotoxin and hydrocortisone succinate on the renal uptake of gentamicin in rats. Animals were injected intravenously with endotoxin (0.25 mg/kg) and/or hydrocortisone (25 mg/kg) plus gentamicin (10 mg/kg). Gentamicin levels in the serum and renal parenchyma as well as renal function and histology were evaluated. Both endotoxin and hydrocortisone given alone increased the concentration of gentamicin in the renal cortex (P less than 0.05). Normal values in serum were observed in all groups at most time intervals. When administered together, endotoxin and hydrocortisone did not potentiate each other. The combination of endotoxin and hydrocortisone gave significantly higher levels of gentamicin than endotoxin or hydrocortisone alone when endotoxin was injected 3 h before hydrocortisone (P less than 0.05). Blood pressure and cardiac frequency were normal when gentamicin was given. Endotoxin alone slightly decreased the glomerular filtration rate, and hydrocortisone alone slightly modified renal plasma flow. The combination of both drugs did not significantly affect renal function. No histological lesion was noted on light microscopy in animals receiving endotoxin. Competitive or synergistic activity of endotoxin, gentamicin, and hydrocortisone at the cellular level, especially on membranes or lysosomes, might explain in part our observation on the renal uptake of gentamicin. By increasing the total amount of drug within the kidney, endotoxin and hydrocortisone might increase the risk of nephrotoxicity associated with aminoglycosides.

Fundamental and clinical studies were performed on a newly developed carbapenem antibiotic, imipenem/cilastatin sodium (MK-0787/MK-0791), and results were summarized as follows. The antibacterial activity of MK-0787 at an inoculum of 10(6) cells/ml against strains of S. aureus which were sensitive or resistant to cefazolin (CEZ), E. coli, P. mirabilis, K. pneumoniae, S. marcescens and P. aeruginosa were determined and compared with activities of ceftazidime (CAZ), CEZ, cefmetazole (CMZ), ceftizoxime (CZX), latamoxef (LMOX), cefamandole (CMD), cefoperazone (CPZ), cefsulodin (CFS) and piperacillin (PIPC). The peak MIC of MK-0787 was less than or equal to 0.024 micrograms/ml against S. aureus, which were sensitive or resistant to CEZ, 0.10 micrograms/ml against E. coli, P. mirabilis, or K. pneumoniae, 0.39 micrograms/ml against S. marcescens and 1.56 micrograms/ml against P. aeruginosa. The antibacterial activity of MK-0787 against these bacteria was, on the whole, superior to that of CAZ, CEZ, CMZ, CZX, LMOX, CMD, CPZ, CFS or PIPC. The pharmacokinetics of MK-0787/MK-0791 was studied in 10 children at dose levels of 10 mg/10 mg/kg and 20 mg/20 mg/kg by a 30-minute intravenous drip infusion. Maximum serum levels of MK-0787, at dose levels of 10 mg/10 mg/kg and 20 mg/20 mg/kg were 41.6 micrograms/ml and 72.9 micrograms/ml, respectively, at the end of infusion and 0.1 micrograms/ml at 6 hours, respectively, after drip infusion. The half-life of both dose levels was 0.9 hour. Mean peak serum levels of MK-0791, at dose levels of 10 mg/10 mg/kg and 20 mg/20 mg/kg, were 49.7 micrograms/ml and 87.0 micrograms/ml, respectively, with half-life of 1.1 and 0.6 hour, respectively. Urinary recovery rates of MK-0787 for 6 hours at dose levels of 10 mg/10 mg/kg and 20 mg/20 mg/kg, were 47.8-82.7% and 25.5-78.0%, respectively, and of MK-0791 for 6 hours were 51.7-93.4% and 40.3-94.4%, respectively. Twenty-four patients, including 1 with purulent meningitis, 1 with septicemia, 1 with pyothorax, 10 with bronchopneumonia, 7 with pyelonephritis and 4 with infections of cutaneous soft tissue were treated with MK-0787/MK-0791 at dose levels of over 100 mg/100 mg/kg/day with purulent meningitis and septicemia and 28.8 mg/28.8 mg-72.8 mg/72.8 mg/kg/day with other infections. The clinical response in all patients was excellent or good.(ABSTRACT TRUNCATED AT 400 WORDS)

A total of 516 strains of Escherichia coli were screened for the presence and expression of the aerobactin iron uptake system. The incidence was markedly higher among clinical isolates from patients with septicemia (68.8%), pyelonephritis (74.6%), and symptomatic (59.8%) and asymptomatic (63.2%) lower urinary tract infections than among normal human fecal isolates (34.3%).

Thirty patients (17 male, 13 female; age 17 to 84 years; normal renal function in 23 cases) with severe bacterial infections were treated with ceftriaxone. The infections was septicemia in 20 cases, a septicemia-like condition in 2 and a focal infection in 8 (2 abscesses of the lung, 2 pyelonephritis, 1 abscess of the liver, 1 subphrenic abscess, 1 meningitis developed from an abscess of the brain and 1 acute intestinal infection). 25 infections were bacteriologically documented, with recovery of the following pathogens: 20 Gram negative rods (including 10 E. coli) that were all susceptible to ceftriaxone (MIC = 0.02 to 0.5 mg/l) except 2 (1 Pseudomonas and 1 E. cloacae), 5 susceptible Gram positive cocci (3 Pneumococcus, 1 Streptococcus and 1 Staphylococcus epidermidis) and 3 susceptible anaerobes (2 B. fragilis and 1 B. melaninogenicus). Ceftriaxone was given alone in 15 cases and in association with another antibiotic in 15 cases (aminoglycoside in 10 cases, nitroimidazole in 4 and fosfomycin in 1). The dose of ceftriaxone was 1 to 2 g per day in 28 cases, 3 g per day in 1 case (meningitis with abscess of the brain) and 1 g every other day in 1 case (chronic renal failure under hemodialysis). Duration of treatment ranged from 10 to 62 days (average 17 days). The usual routes of administration were IV and IM; the SC route was used on 4 occasions. Pharmacokinetic studies of serum levels were carried out in several patients including two who had ceftriaxone subcutaneously; results were consistent with those previously reported in the literature.(ABSTRACT TRUNCATED AT 250 WORDS)

We investigated the clinical efficiency and safety of ofloxacin, a new fluoroquinolone, for the treatment of various documented bacterial infections in 26 patients (10 females, 16 males) aged 17 to 84 years. Ofloxacin monotherapy was given orally in a dose of 200 mg twice (25) or three times (1) a day. Antibiotic levels and serum bactericidal activity were measured using a microbiological method on the second and sixth days, before and 2 and 6 hours after a single dose. The infectious episode treated was enterocolitis in 7 cases (5 Shigella, 2 Salmonella), Salmonella septicemia in 9 (7 typhoid fevers and 2 Salmonella minor infections), chronic osteoarthritis in 3 (1 E. coli, 2 S. aureus + P. aeruginosa), a soft tissue infection in 3 (2 S. aureus, 1 E. coli), acute pleuropneumonia in 2 (2 Klebsiella pneumoniae), pyelonephritis with bacteremia in 1 (Klebsiella pneumoniae), and pneumococcal pneumonia with septicemia in 1. Mean duration of therapy was ten days for 23 patients (range 7 to 30 days). The three patients with osteoarthritis were treated for 35, 95 and 270 days respectively. 24 patients recovered free of sequelae or germ carriage. Treatment failed in 1 case of chronic osteitis (S. aureus + P. aeruginosa) and in 1 staphylococcal soft tissue infection. No adverse reactions were observed except a slight increase in transaminases in 3 patients. Peak and through serum ofloxacin levels were 3.70 micrograms/ml and 0.95 micrograms/ml respectively on the second day and 3.25 micrograms/ml and 0.80 microgram/ml respectively on the sixth day.(ABSTRACT TRUNCATED AT 250 WORDS)
