1/142. Subcutaneous nodules caused by pseudomonas aeruginosa without sepsis.pseudomonas aeruginosa infection can cause a wide array of skin manifestations. While some infections are mild, as are the cases with hot tub folliculitis and toe web or nail infection, others are a result of sepsis and can be fatal without prompt treatment. The classic skin finding of P. aeruginosa sepsis is ecthyma gangrenosum, but other signs such as papules, petechiae, and hemorrhagic bullae can also be seen. Suppurative panniculitis can also be caused by P. aeruginosa sepsis and clinically manifests as solitary or multiple subcutaneous nodules. Reports in the literature describe these nodules in the setting of clinical sepsis or with positive blood cultures. We report a case of localized subcutaneous nodules on the leg caused by P. aeruginosa in a patient without sepsis or positive blood cultures. The source of the infection was thought to be from a traumatic inoculation. This raises the possibility that P. aeruginosa can cause subcutaneous nodules from a localized infection, perhaps via lymphangitic spread without the manifestations of sepsis.- - - - - - - - - - ranking = 1keywords = spread (Clic here for more details about this article) |
2/142. Subcutaneous nodules with pseudomonas septicaemia in an immunocompetent patient.Pseudomonas septicaemia presenting with subcutaneous nodules, though rare, is well described in immunocompromized populations. It is, however, very uncommon in immunocompetent patients. We describe a case of a 42-year-old woman who presented with community-acquired. pseudomonas aeruginosa septicaemia and subcutaneous nodules. No precipitating cause or immune dysfunction was found. She was successfully treated with appropriate antibiotics, respiratory and cardiovascular support in the intensive care Unit. The difficulty in eradicating the organism from the skin lesion and the need for investigating the immune function of septicaemia patients are discussed.- - - - - - - - - - ranking = 0.62899720722235keywords = unit (Clic here for more details about this article) |
3/142. Community acquired pseudomonas aeruginosa pneumonia.pseudomonas aeruginosa is an uncommon cause of community acquired pneumonia in immunocompetent hosts. We report two cases that did well once appropriate and prolonged antimicrobial therapy was initiated. They had no evidence of immune deficiency. The initial consideration was pulmonary tuberculosis in both cases given the subacute presentation, significant weight loss, and findings on chest roentgenogram.- - - - - - - - - - ranking = 3.1449860361118keywords = unit (Clic here for more details about this article) |
4/142. Pseudomonas-induced bilateral endophthalmitis with corneal perforation in a neonate.Neonatal endophthalmitis is a rare entity that may be exogenous or endogenous. pseudomonas aeruginosa is a ubiquitous gram-negative rod that may appear as a nosocomial source of infection in the neonatal intensive care unit. A case of bilateral Pseudomonas-induced endophthalmitis is presented, and a discussion of the case and of the relevant literature follows.- - - - - - - - - - ranking = 0.62899720722235keywords = unit (Clic here for more details about this article) |
5/142. Community-acquired pseudomonas stutzeri vertebral osteomyelitis in a previously healthy patient: case report and review.pseudomonas stutzeri is a rare pathogen, and its recovery is often associated with colonization and contamination. We report a case that, to our knowledge, is the first of community-acquired P. stutzeri vertebral osteomyelitis in a previously healthy patient, and we review the literature regarding infections with this uncommon organism. Of the 29 previously reported cases of P. stutzeri infection cited in the literature, only two resulted in death, reflecting the relatively low degree of virulence of this organism. Predisposing risk factors for P. stutzeri infection can be categorized as follows: (1) previous surgery or procedure (implying probable nosocomial acquisition), with or without a foreign body; (2) immunocompromise (an underlying predisposition to infection by an organism with low virulence); (3) immunocompromise and a previous procedure; and (4) previous trauma or superficial infection, with or without possible nosocomial contamination. Our patient lacked any known risk factors for either pyogenic vertebral osteomyelitis or P. stutzeri infection.- - - - - - - - - - ranking = 3.1449860361118keywords = unit (Clic here for more details about this article) |
6/142. 'Hot tub folliculitis'. Test the waters--and the patient--for Pseudomonas.A healthy 10-year-old boy presented with a widespread, nonpruritic, pustular rash of 3 days' duration. He reported having no fever, chills, or other systemic symptoms. physical examination revealed perifollicular pustules concentrated in the swimsuit area, with fewer widely scattered lesions on the trunk and extremities (figure 1). His mother reported that he had bathed in a hot tub on the evening before onset of the rash. A similar rash had developed in two other boys who had bathed with the patient. No laboratory tests or cultures were performed. The patient was empirically treated with erythromycin tablets, 250 mg twice daily for 10 days. His mother was instructed to contact the owners of the hot tub so that it could be properly cleaned and maintained. Within 1 week the rash had completely resolved.- - - - - - - - - - ranking = 1keywords = spread (Clic here for more details about this article) |
7/142. ecthyma gangrenosum in an AIDS patient with normal neutrophil count.ecthyma gangrenosum is the cutaneous manifestation of pseudomonas aeruginosa septicemia, typically affecting immunosuppressed patients, particularly those with neutropenia. association with hiv disease has been rarely reported.

8/142. Usefulness of procalcitonin in Pseudomonas burn wound sepsis model.Procalcitonin (PCT), a precursor of calcitonin, and endotoxin were determined in the burn wound sepsis model in which 21 Sprague-Dawley rats were scalded approximately 30% on their back. On day 2 post burn, the wounds were inoculated 1 x 10(8) colony-forming units of pseudomonas aeruginosa. On day 5 post burn P. aeruginosa was detected by blood culture in 10 of the 21 rats (47.6%). The mortality rate 7 days after burn was 90.5%. Significant correlations were observed between serum endotoxin levels and serum PCT levels on day 5 post burn (r = 0.860, p<0.001). It was suggested that endotoxin may induce the release of PCT and that measuring the levels of PCT may be useful in diagnosing burn wound sepsis.- - - - - - - - - - ranking = 0.62899720722235keywords = unit (Clic here for more details about this article) |
9/142. bacteremia, meningitis, and brain abscesses in a hospitalized infant: complications of pseudomonas aeruginosa conjunctivitis.This report describes a preterm infant hospitalized in a neonatal intensive care unit who developed pseudomonas aeruginosa conjunctivitis associated with bacteremia, meningitis, and multiple brain abscesses. P. aeruginosa conjunctivitis can rapidly progress to an invasive eye infection, such as corneal ulceration or endophthalmitis, leading to poor vision or blindness. Progression of this infection may lead to systemic disease. However, as illustrated in this report, P. aeruginosa conjunctivitis may be associated with the development of systemic complications such as bacteremia and meningitis in the absence of invasive eye disease. P. aeruginosa is a relatively common cause of conjunctivitis in hospitalized preterm and low birth weight infants. Given the severity of the ocular and systemic complications of Pseudomonas conjunctivitis, clinicians are reminded that prompt detection and treatment of neonatal conjunctivitis is critical.- - - - - - - - - - ranking = 0.62899720722235keywords = unit (Clic here for more details about this article) |
10/142. ecthyma gangrenosum as a manifestation of Pseudomonas sepsis in a previously healthy child.We present a case of pseudomonas aeruginosa sepsis heralded by ecthyma gangrenosum in a previously healthy 15-month-old child. Pseudomonas infection and its uncommon skin manifestation are rarely encountered in an immunocompetent child. This case highlights the critical importance of identifying ecthyma gangrenosum to institute optimal antimicrobial therapy.- - - - - - - - - - ranking = 10.907627557113keywords = count (Clic here for more details about this article) |
