Nosocomial bloodstream infections in ICU and non-ICU patients.

BACKGROUND: Nosocomial bloodstream infections (BSI) create a serious health problem in hospitals all over the world. The objectives of our study were to explore putative disease markers and potential risk factors with nosocomial BSI in patients in intensive care units (ICU) and non-ICU patients and to determine risk factors associated with increased 28-day mortality rate in patients with nosocomial BSI acquired in combined medical-surgical ICU. However, the major purposes of this report were to identify epidemiologic differences between nosocomial BSI acquired in ICU and non-ICU, as well as analyses outcomes for patients with nosocomial BSI acquired in ICU. METHODS: A 1-year prospective cohort study was performed to determine the incidence of nosocomial BSI in hospitalized patients. Patient characteristics, risk factors related to health care, and source of infection of patients with BSI acquired in non-ICU were compared with those patient with BSI acquired in ICU. Also, nested case-control study of patients to nosocomial BSI acquired in ICU was performed to evaluate outcome. Patients were identified by active surveillance and positive blood culture during the study period. RESULTS: The incidence of nosocomial BSI was 2.2 per 1000 admission in non-ICU patients and 17.4 per 1000 admission in ICU patients. The 28-day crude mortality rate was 69% in ICU patients. A multivariate model showed that nasogastric tube (RR, 25.1; 95% CI: 3.845-163.85; P=.001), mechanical ventilation (RR, 13.04; 95% CI: 1.974-96.136; P=.008), and H2 blockers (RR, 12.16; 95% CI: 1.748-84.623; P=.012) were more prevalent among patients with BSI acquired in ICU, and aggressive procedures (RR, 8.65; 95% CI: 1.70-44.00; P=.009) were more prevalent among patients with BSI acquired in non-ICU patients. Risk factors independently associated with increased 28-day mortality rate in ICU patients were mechanical ventilation (OR, 8.63; 95% CI: 1.5-49.8; P=.016) and SAPS II >40 (OR, 6.0; 95% CI: 1.0-35.7; P=.049). The most common isolated nosocomial BSI pathogens (in both groups of patients) were coagulase-negative staphylococci (21%), Staphylococcus aureus (14%), and Klebsiella species (13%). Klebsiella species was the only organism independently influencing the poor outcome of nosocomial BSI in ICU patients (OR, 4.3; 95% CI: 1.2-15.3; P=.022). CONCLUSIONS: Our results show epidemiologic differences between non-ICU and ICU BSI. Also, this study suggests that severity of underlying host conditions, mechanical ventilation, and microbial agents (Klebsiella species) affect the outcome of NBI in patients in ICU.

[Necrotizing fasciitis caused by group A streptococcus].

The first case of the confirmed necrotizing fasciitis caused by Group A Streptococcus in Yugoslavia was presented. Male patient, aged 28, in good health, suddenly developed symptoms and signs of severe infective syndrome and intensive pain in the axillary region. Parenteral antibiotic, substitutional and supportive therapy was conducted along with the radical surgical excision of the necrotizing tissue. The patient did not develop streptococcal toxic shock syndrome thanks to the early established diagnosis and timely applied aggressive treatment. He was released from the hospital as completely cured two months after the admission.

[Multiorgan tuberculosis].

Tuberculosis is an unusual infectious disease because of the latent period between the infection and the appearance of the disease may be prolonged for many weeks, months, or years as it is in case of the secondary tuberculosis. Tuberculosis in organs other than the lung has been observed for many years but has not always been recognized as tuberculosis, and it has been given many names. Extrapulmonary tuberculosis gained new importance, because it represented a progressively greater proportion of new cases. Multiple extrapulmonary sites were reported rarely except for one anatomical site, which was reported frequently. Extrapulmonary rates increase with age, so there are marked differences in age in specific rate patterns among the sites. Extrapulmonary tuberculosis occurred in respiratory organs other than lung, such as lymphatic, urogenital, and central nervous system, abdominal, osteoarticular, as well as tuberculosis of other organs such as skin, pericardium and endocrine glands. This case was reported to analyse clinical, morphologic and laboratory characteristics, method of diagnosis and the outcome in patients with multiorgan tuberculosis in order to explore the factors which might contribute to the decision making, concerning these forms of tuberculosis. Recent knowledge of pathogenesis was summarized as well as clinical presentation and the effects of cytokines produced by T lymphocytes and cellular population on antimycobacterial immune defences, and also susceptibility to tuberculosis. Mortality remains high and the treatment should start as soon as tuberculosis is suspected.

[Primary localized cutaneous amyloidosis--lichen amyloidosis].

This case report presented a female patient with primary-localized-cutaneous-amyloidosis in the form of lichen amyloidosus. Primary-localized-cutaneous-amyloidosis is a rare idiopathic dermatosis caused by abnormal deposition of amyloid composed primarily of degenerated keratin filaments. In order to establish the final diagnosis, detailed clinical and laboratory investigations were performed, with a particular emphasis on pathohistological analysis of skin specimens, special stains, and electron microscopy.
