Seventy nine cases of sporadic, community acquired legionnaires' disease have been reviewed. Annual and seasonal variation in incidence was noted. The mean age of the patients was 53 years and 50 (63%) were male. Pre-existing chronic diseases were present in only 23 (29%), including two patients receiving immunosuppressive treatment. Common symptoms included unproductive cough, dyspnoea, chest pain, headache, confusion, nausea, vomiting, and diarrhoea. Respiratory symptoms were absent, however, in 17 (22%). Localising chest signs were present in 74 (95%) cases. Frequent laboratory findings included lymphopenia, high erythrocyte sedimentation rate, hyponatraemia, raised urea and creatinine concentrations, abnormal liver function, hypophosphataemia, hypoalbuminaemia, proteinuria, and haematuria. Thirteen patients died (16%), including nine of 20 who received assisted ventilation. The mortality rate in patients treated with erythromycin (11%) was lower than in those who received other antibiotics (23%), but this difference was not statistically significant. Of the features noted on admission, only a high plasma urea concentration was significantly associated with death. Sporadic community acquired legionnaires' disease is a not uncommon disorder, which with appropriate treatment has a prognosis similar to that of other forms of community acquired pneumonia.

Diagnostics of the HIV Infection The clinical picture of an acute HIV infection resembles that of mononucleosis with lymphadenopathy, fatigue and fever. In this phase, the infection can be diagnosed with certainty only through direct virus detection. During the subsequent latent phase, recurring or serious progressive skin manifestations from different illnesses, prominent candidiasis of the oral cavity and community acquired pneumonia frequently occur. Ulcerations in atypical locations of the gastrointestinal tract could also indicate an HIV infection. For cases of clear lymphopenia, an HIV infection should be definitely considered. Above all, the presence of non-Hodgkin's lymphoma is characteristic of the complete clinical picture of AIDS. An appropriate diagnostic test (antibody test or detection of HIV) is urgently indicated in situations that carry a high risk for HIV transmission. This applies, above all, to patients whose partner is HIV positive, to patients who frequently change sex partners, to prostitutes and to intravenous drug users.

The case is presented of a 38 year-old patient who was admitted in the Emergency Department due to a severe acute respiratory failure and who was transferred to the Critical Care Unit with a suspected initial diagnosis of community acquired pneumonia caused by an atypical microorganism, which was complicated with an acute respiratory distress syndrome. This was able to be treated with non-invasive mechanical ventilation. At 48 hours after admission, the growth of Gram negative bacilli in the blood culture was reported, which was subsequently identified as Salmonella enteritidis. This information, along with the lymphopenia suffered by the patient, suggested an immunodepressed state, thus serological tests were performed which showed positive for HIV. Antibiotic treatment was started based on the microbiological findings, with a favourable clinical outcome for the patient.
