1/5. A rare case of Salmonella-mediated sacroiliitis, adjacent subperiosteal abscess, and myositis.We report the case of a 16-year-old female who was ultimately diagnosed with Salmonella sacroiliitis, adjacent subperiosteal abscess, and myositis of the left iliopsoas, gluteus medius, and obturator internus muscles. Early and accurate recognition of this syndrome and other infectious musculoskeletal syndromes can prove difficult for the emergency physician, as these disease processes require special attention to pain of proportion to physical findings and a high index of suspicion.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/5. Atypical bacterial infections explained by a concomitant virus infection.Because both viral and bacterial infections are common during early childhood, dual infections are not unexpected. However, the clinical manifestation of such combined infections may be, difficult to interpret, and they are often misdiagnosed as "atypical bacterial infection." Five patients with concomitant viral-bacterial infections are described. In all five cases, virus detection enabled the physicians to better understand an otherwise puzzling clinical presentation. In view of the recent progress in rapid viral diagnoses and the potential of antiviral drugs, the possibility of dual infection should be investigated more often.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
3/5. Endogenous endophthalmitis due to salmonella typhimurium.Endogenous endophthalmitis due to salmonella typhimurium is reported in a 1-year-old child. Despite vigorous antibiotic therapy, the child's vision deteriorated, and loss of light perception occurred in the infected eye. endophthalmitis is a very rare complication of salmonellosis, and it should alert physicians because of its severe damage to the eye.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
4/5. Concurrent falciparum malaria and Salmonella bacteremia in travelers: report of two cases.fever in travelers or immigrants from the tropics is an increasingly common problem facing physicians in urban centers of north america. malaria and typhoid fever are endemic in developing countries and affect millions of people annually. An association between falciparum malaria and salmonella bacteremia has been noted for many years, although the underlying mechanisms have not been fully elucidated. We report on two travelers with falciparum malaria and concomitant salmonella bacteremia and review the possible mechanisms that may explain this association.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
5/5. The impact of bacteraemia on hiv infection. Nine years experience in a large Italian university hospital.The object of this case control study was to evaluate the frequency, the risk factors, the microbiological spectrum and the outcome of 249 cases of bacteraemia observed in 209 hiv-infected patients, most them affected by AIDS. The rate of bacteraemia in the total yearly hiv-related admissions increased from 4% in 1985 to 13% in 1993. The more common aetiological agents of bacteraemia were: staphylococcus aureus (29.7%), non-typhoidal species of Salmonella (14.1%), staphylococcus epidermidis (10.9%), streptococcus pneumoniae (8.4%) and pseudomonas aeruginosa (7.6%). A mixed flora was found in 14% of the episodes. multivariate analysis of predisposing factors indicated that a low CD4 T-cell count (<0.2 x 10(9)/l) (P=0.01), use of central venous catheters (CVC) (P=0.01) and neutropenia (polymorphonuclear neutrophils <1.0 x 10(9)/l) (P=0.04) were independent risk factors for the development of bacteraemia. Logistic regression did not reveal any association of bacteraemia with intravenous drug abuse (on univariate analysis P=0.04). The response (31.8%). Recurrences to specific therapy was favourable in 170 episodes (68.2%); death occurred in 79 (31.8%). Recurrences arose in 40 patients, 17 (42.5%) of them died. The outcome of bacteraemia was influenced by a low number of CD4 T-cells (P<0.001) but not of polymorphonuclear cells. Our findings suggest that bacteraemia is a relatively common event in hiv-infected patients, especially under particular conditions (e.g. intravenous drug abuse, use of CVC, neutropenia and a low CD4-T-cell count). It requires special attention from physicians who must recognise and treat the condition promptly at an early stage.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
