During the last few years, among nosocomial pathogens, Acinetobacter spp. have given rise to an increasing number of nosocomial infections. Acinetobacter strains are widely distributed in nature; in hospitals, the human skin is the likely source for most outbreaks of hospital infections. The organism has been frequently found in the inanimate environment, especially in moist situations and it has been isolated from various types of opportunistic infections (septicaemia, endocarditis, meningitis, pneumonia, skin and wound sepsis and urinary tract infection). For epidemiological studies, various typing methods such as biotyping, bacteriocin typing and serology have been developed. More recently electrophoretic patterns of cell-envelope proteins and plasmid analysis have proved useful in differentiating outbreak strains. Antibiogram typing may be useful but the antibiotic resistance of Acinetobacter spp. has changed rapidly within the last few years and thus antibiotyping must be complemented by other typing systems. New methods such as electrophoretic analysis of isoenzymes, definition of plasmidotype profiles or restriction endonuclease digestion of chromosomal DNA are under investigation.

One hundred and ninety-three nephrotic children with a total of 271 admissions during the past decade, from 1980 to 1989, were retrospectively reviewed for acute complications and unusual features of nephrotic syndrome. One hundred and forty-nine patients were male, 44 female. Hypertension was found in 41 children (21.2%). Nine patients (4.7%) had a total of 11 episodes of hypovolemic shock. These shock patients had a more severe hemoconcentration (mean hemoglobin concentration 19.6 +/- 1.5 g/dl) and hyponatremia (mean serum sodium 127.5 +/- 8.5 mmole/L). Bacterial infections occurred in 28 children (14.5%) with primary peritonitis in 13, sepsis in 6, cellulitis in 4, urinary tract infection in 4 and osteomyelitis in 1. Almost all infections were caused by gram-negative bacilli. Other complications or features included tetany in 4 (2.1%), thromboembolism in 2 (1.0%), pancreatitis in one (0.5%) and Fanconi syndrome in one (0.5%).

Despite significant advances in obstetric and pediatric health care, group B beta-hemolytic Streptococcus (GBS) remains one of the most prevalent and devastating pathogens in peripartum women and their newborn infants. It may cause urinary tract infection, chorioamnionitis and endometritis, bacteremia, and cesarean wound infection in the peripartum period. Moreover, GBS accounts for nearly 50% of serious neonatal bacterial infections. Approximately three in every 1,000 children born in the United States acquire pneumonia, sepsis, or meningitis from GBS, with combined mortality and morbidity exceeding 50% despite appropriate antibiotic and supportive therapy. Estimates indicate that more than 10,000 infants are affected annually, at a cost of more than $300 million. Neonatal disease is divided into early- and late-onset syndromes: The illness emerging after six days of age differs in terms of GBS serotype, clinical manifestations, and outcome from the disseminated process seen in earlier onset. We describe two infants infected with GBS and discuss risk factors, pathogenesis, diagnosis, therapy, and options for disease prevention in the peripartum woman and her infant.

Risk factors, clinical syndromes and the case-fatality rates associated with Group B Streptococcus (GBS) infections in infants managed at the University of Rochester Medical Center during 1979 to 1989 were reviewed. Overall 92 episodes of early onset disease (EOD) and 54 of late onset disease (LOD) were diagnosed in 143 infants (3 infants with EOD presented later with LOD). About one-third of patients with EOD and controls were non-white compared with two-thirds of patients with LOD that occurred in racial minority groups. Prematurity and low birth weight were significantly more common in patients with invasive GBS disease than in controls. Eighty-three of 92 (90%) cases of EOD were detected during the first day of life and 10 of 54 (19%) cases of LOD occurred in infants older than 3 months of age. At the time of diagnosis 4% of infants with EOD were asymptomatic, 54% had respiratory disease, 27% had sepsis without a focus, 15% had meningitis and 1% had urinary tract infection or omphalitis. Among infants with LOD 46% had sepsis, 37% meningitis, 7% urinary tract infection, 6% osteomyelitis and/or septic arthritis and 4% cellulitis or pneumonia. Leukopenia and shift to the left were observed in 43 and 61% of episodes of EOD and in 28 and 57% of episodes of LOD, respectively. All infants were promptly treated with antibiotics and vigorous supportive therapy. The case-fatality rate was 13% in EOD and 0 in LOD.(ABSTRACT TRUNCATED AT 250 WORDS)

Strictly enforced antibiotic formulary restriction in combination with formulation of agreed guidelines for antibiotic use in common infection problems such as septicemia, febrile neutropenia, urinary tract infection, biliary sepsis, liver abscess, peritonitis, nosocomial pneumonia, soft tissue infection and purulent meningitis, generated a combined savings of 307,748.5 bahts or 13.5 per cent cost reduction over a 6 month period, and improved quality of use, appropriate 54.8 vs 67.5 per cent, statistically significance (P less than 0.002). Although this saving was offset in part by increased spending of unrestricted antibiotics, such as Penicillin and Gentamicin, an overall cost saving remained. In the months during the restrictions, no significant changes occurred regarding patients response and mortality. However, after the onset of the controls, it was revealed that antibiotics were more appropriately used afterwards. This study has shown, most importantly, that savings were achieved with no negative effect on good patient care. Moreover, the antibiotic use control was operationally successful, most house-staff and attending physicians, not only antibiotic evaluating team, have accepted the program in a very positive way. Overall, this program successfully achieved its initial goal, cost saving without compromising good medical practice. We are now continuing our program and also trying to modify so that it will be useful to all departments in the hospital.

To evaluate pharmacokinetics and clinical efficacy of flomoxef (6315-S, FMOX) in neonates, FMOX was administered to 21 neonates. With 20 mg/kg and 40 mg/kg of intravenous drip-infusion of FMOX 60 minutes, half lives (T 1/2's) was 64.9 minutes and 130.3 minutes, respectively, and when 20 mg/kg of FMOX was infused intravenously to 2 cases, half lives were 70.8 minutes and 110.1 minutes, respectively. When 45-100 mg/kg of FMOX was administered to 17 neonates with infections (pneumonia 8, sepsis 1, sepsis suspected 2, intrauterine infection 2, urinary tract infection 2, omphalitis 2), the efficacy rate was 88.2% (15 of 17). No adverse reactions were observed clinically in the 21 neonates. Transient elevation of eosinophilia was observed in 1 case and transient elevation of S-GOT and S-GPT 1 in another. These results suggest that FMOX is an effective and safe antibiotic to use in neonates.

Infectious complications following urologic surgery include bacteriuria, bacteremia, sepsis, acute pyelonephritis, and wound infection. Antimicrobial prophylaxis reduces the risk of some of these complications and is recommended in transrectal core biopsy of the prostate, transurethral surgery, open prostatectomy, and stone surgery. Prophylaxis does not appear to be beneficial in patients undergoing transrectal needle or transperineal core biopsy of the prostate, cystoscopy, orchiectomy, hydrocelectomy, and simple nephrectomy. Patients with urinary tract infection preoperatively should receive antimicrobial treatment prior to surgery.

Urinary retention following total hip and knee arthroplasty is a common problem frequently necessitating either prolonged urethral catheter drainage or intermittent catheterization. The direct relationship of urinary tract instrumentations, procedures, and infections to deep sepsis in total hip replacements is well documented. Pharmacologic therapy to stimulate voiding or augment bladder emptying is thus theoretically preferable to the use of catheterization. Prasozin hydrochloride, an alpha blocker, relaxes the smooth musculature of the posterior urethra and prostrate and has been used to treat urinary obstruction secondary to benign prostatic hypertrophy. A prospective study in 60 male patients showed a statistically significant decrease in postoperative urinary retention with the perioperative administration of prazosin (p less than 0.01). A higher incidence of urinary tract infection was seen in patients who developed urinary retention (3% versus 20%) (p less than 0.01). Uroflowmetry parameters were not predictive of the patient at risk for retention and were unaltered with the administration of prazosin. Prazosin can be an effective adjunct in the prophylaxis of postoperative urinary tract infections and may decrease the potential risk for total joint sepsis.

Medical complications may account for 30% or more of the deaths resulting from acute ischemic stroke in the elderly. In descending order of frequency, the most deadly complications are bacterial pneumonia, pulmonary embolism, myocardial infarction, and sepsis without pneumonia (often in the setting of a urinary tract infection or a necrotic decubitus). Normal aging is associated with declining pulmonary and cardiovascular functions as well as declining immunocompetence and physical barriers to infection. The neurological effects of acute ischemic brain injury compound these susceptibilities. Accordingly, a high degree of vigilance is emphasized in the diagnostic and therapeutic guidelines provided for care of the lungs, the heart, the urinary tract, and the skin. Guidelines are also provided for management of blood pressure during the first hours and days following stroke onset. Treatment should be withheld unless specific medical indications are identified. When antihypertensive agents are administered, the appropriate dose may be lower than usually recommended (e.g. labetalol) in order to minimize abrupt drops in blood pressure that may result in further injury to potentially viable ischemic brain tissue.

Bacteriological and clinical studies on cefodizime (CDZM, THR-221), a new cephem developed by Hoechst AG and Roussel Uclaf, were carried out and the results are summarized below: 1. Against Gram-positive bacteria, Staphylococcus aureus, Streptococcus pyogenes and Streptococcus pneumoniae, antibacterial activities of CDZM were similar to those of cefotaxime (CTX), cefazolin, cefotiam and piperacillin. Against Escherichia coli, Klebsiella pneumoniae and Serratia sp., antibacterial activities of CDZM were similar to that of CTX, and superior to those of other tested antibiotics. Especially against Haemophilus influenzae and Branhamella catarrhalis, it showed an excellent antibacterial activity. 2. Although the clinical efficacy was poor in 1 patient with sepsis caused by Salmonella marcescens and in another with cervical lymphadenitis, in 5 patients with upper respiratory tract infection, 4 patients with bronchitis, 6 patients with bronchopneumonia, 18 patients with pneumonia, 5 patients with urinary tract infection and 1 patient with enteritis, the clinical efficacy was excellent or good and the efficacy rate was 95.1% (39/41) including excellent efficacies in 25 cases. 3. Bacteriologically, all identified causative bacteria were eradicated except for 1 case of Salmonella sp., thus the eradication rate was 97.4% (38/39). Especially S. pneumoniae in 10 cases, H. influenzae in 12 cases and B. catarrhalis in 3 cases were eradicated totally. 4. Adverse reactions were studied in 46 cases, and digestive symptoms were observed in 9 cases (diarrhea 5 cases, loose stools 4 cases). Eruption and vascular pain were observed in 1 case each. As digestive symptoms in 9 cases were mild, the treatment were not suspended. In laboratory test values, elevation of GOT, elevation of GPT, elevation of bilirubin, and eosinophilia were observed in 1 case each. Influences on blood coagulation parameters were studied. No change was observed between the beginning and the end of the treatment. From above results, we have concluded that CDZM is a useful and safe antibiotic in pediatrics, administered at a daily dose of 20 mg/kg divided into 3 or 4 doses and administered intravenously.
