Mycotic aneurysm of the internal carotid artery--a case report.

Extracranial internal carotid artery (ICA) mycotic aneurysms are rare entities that may result in significant neurologic morbidity and mortality. Several operative techniques have been described in the literature for the management of this difficult condition. This case report describes a contained ruptured mycotic aneurysm of the extracranial ICA associated with Proteus mirabilis infection successfully treated by an end-to-end spatulated interposition saphenous vein graft.

Spontaneous bacterial peritonitis causing Serratia marcescens and Proteus mirabilis ventriculoperitoneal shunt infection. Case report.

The authors report their experience treating a polymicrobial ventriculoperitoneal (VP) shunt infection in a developmentally delayed 21-year-old woman. Cerebrospinal fluid (CSF) cultures grew Serratia marcescens and Proteus mirabilis. On admission and throughout her hospitalization, results of physical examination of her abdomen were normal, and radiographic studies showed no evidence of bowel perforation or pseudocyst formation. Contrast-enhanced computed tomography of the abdomen revealed a small fluid collection. After a course of intravenous gentamicin and imipenem with cilastatin in conjunction with intrathecal gentamicin, the infection was resolved and the VP shunt was reimplanted. Although VP shunt infections are not uncommon, S. marcescens as a causative agent is exceedingly rare and potentially devastating. Only two previous cases of S. marcescens shunt infection have been reported in the literature. Authors reporting on S. marcescens infections in the central nervous system (CNS) have observed significant morbidity and death. Although more common, the presence of P. mirabilis in the CSF is still rare and highly suggestive of bowel perforation, which was absent in this patient. Spontaneous bacterial peritonitis was the likely source from which these bacteria gained entrance into the VP shunt system, eventually causing ventriculitis in this patient. The authors conclude that in light of the high morbidity associated with S. marcescens infection of the CNS, intrathecal administration of gentamicin should be strongly considered as part of first-line therapy for S. marcescens infections in VP shunts.

A comparison of cefaclor versus trimethoprim-sulfamethoxazole combination in the treatment of acute urinary infections.

Acute lower urinary tract infections were treated in 57 women according to a randomized protocol, using either cefaclor, a cephalosporin whose chemical structure is similar to that of cephalexin, or trimethoprim-sulfamethoxazole combination. Urine cultures were made before treatment was started, midway through the 10-day course of therapy, 1 week after therapy and 4 to 6 weeks after therapy, if possible. Urine cultures in 100 per cent of the patients became sterile during therapy and remained so 1 week after therapy. Of those patients undergoing followup cultures 4 to 6 weeks after therapy 98 per cent had sterile urine. Twenty-nine patients were randomized to cefaclor therapy and 28 received a trimethoprim-sulfamethoxazole combination. There was no difference between the 2 drugs studied in terms of efficacy. No side effects were noted with cefaclor and 2 minor side effects were noted with the trimethoprim-sulfamethoxazole combination. Cefaclor in a twice daily dosage schedule appears to be a safe and useful drug in the treatment of urinary tract infections caused by the common gram-negative organisms and it appears to be as efficacious as the trimethoprim-sulfamethoxazole combination.

Nosocomial infection with highly resistant, Proteus rettgeri. Report of an epidemic.

Over 22-1/2 months an epidemic of at least 127 cases of nosocomial infection developed from a strain of Proteus rettgeri resistant to all antibiotics commonly tested in hospital laboratories. Although there were at least four cases of septicemia and one related death, the majority of cases consisted of asymptomatic bacteriuria or clinically mild urinary tract infection. Indwelling urinary tract devices and antibiotic therapy were important predisposing factors. Data supported an association between increasing use of gentamicin and increasing rates of resistant infection. No common source was found, and contact spread appeared more likely. Control measures included efforts to reduce unnecessary exposure to the incriminated risk factors and to improve asepsis in the management of catheterized patients. An additional 36 cases and one related death were identified in the 7-1/2 months following the investigation and institution of control measures. Nosocomial infection with extremely resistant organisms may pose a serious hazard wherever indwelling urinary tract devices and antibiotics are used together intensively.

[The enterotoxigenic capacity of hemolysin-producing strains of Proteus isolated in acute intestinal infections in children].

The capacity of P. mirabilis and P. vulgaris strains isolated in acute enteric infections in children for producing enterohemolysin, a new type of hemolysin, has been shown. The relationship between the capacity of Proteus cultures for producing enterohemolysin and their capacity for inducing toxic secretory reaction on a ligated loop on the small intestine of rabbits in the absence of known thermostable and thermolabile antitoxin in bacteria.

[Pediatric pharmacology of azlocilin (author's transl)].

Pharmacokinetic investigations of acylureido-penicillins azlocillin in newborns, infants and school shildren showed age dependend results. The differences were especially evident in a prolongation of the serum half-life to 2,56 hours in newborns compared to 0.94 hours in school children. On the basis of our pharmacokinetic results and of the dosages resulting from the data the antibiotic was used clinically in twenty eight patients with Pseudomonas aeruginosa infections and one patient with a Proteus mirabilis infection. The results were much better in infections of the urinary tract than in infections of the respiratory tract. This might be due to an observe bacterial presistence in spite of highly effective levels of azlocillin in bronchial secretion. The tolerance to the antibiotic was good.

Molecular mimicry between HLA-DR alleles associated with rheumatoid arthritis and Proteus mirabilis as the Aetiological basis for autoimmunity.

Molecular mimicry is one of the pathological mechanisms proposed to explain the association between microorganisms and autoimmune diseases. This review deals with the association between bacteria and rheumatic diseases with a special emphasis on rheumatoid arthritis where upper urinary tract infection by Proteus mirabilis is the possible cause of this severe, arthritic condition. Prospective trials involving anti-Proteus therapy should be carried out.
