A previously healthy 24 year old athletic man became ill suddenly with pneumonia the day after swimming in the sea. Despite intensive support measures in the intensive care unit he died three hours after admission and 21 hours after his first symptom. Necropsy showed bilateral haemorrhagic necrotising pneumonia. Aeromonas hydrophila was isolated from a blood culture taken at admission and from the lungs at necropsy. The infection may have come from contaminated sea water.

A male pup Kuril seal (Phoca vitulina stejnegeri) from Hokkaido, Japan, was observed with a unilateral and total cleft of the primary palate. Complications included a supernumerary tooth, hypoplasia and asymmetry of the face, and deformation of the eyeball and external auditory meatus. An accompanying pneumonia may have resulted from water flowing into the respiratory system due to imperfect closure of the nostril by the cleft. No other abnormalities were found.

From May 1985 through July 1990, 28 episodes of Vibrio vulnificus infection in 27 patients were encountered in five major hospitals in Taiwan. The ages of patients ranged from 19 to 76 years; the ratio of male to female patients was 2:1. Eighteen episodes manifested as bacteremia and eight as wound infections alone. One patient each developed gastroenteritis and pneumonia after nearly drowning. Twenty-three patients exhibited skin manifestations. Twenty patients had underlying diseases. All patients were treated with antibiotics, and 14 also underwent some form of surgical treatment (incision and drainage, fasciotomy, debridement, or amputation). Thirteen of the 28 episodes were preceded by precipitating factors; most were due to ingestion of seafood or exposure of abraded skin to salt water. Ten of the 18 septicemic patients died--most within 48 hours of hospitalization. One patient without bacteremia who had a wound infection died. Results of in vitro susceptibility studies suggested that ampicillin or a third-generation cephalosporin would be effective. Susceptibility to aminoglycosides was observed for greater than 90% of isolates. We recommend combined therapy with a third-generation cephalosporin or ampicillin and an aminoglycoside along with appropriate surgical therapy for the treatment of V. vulnificus infection.

Ten days after starting military service in a police barracks a 25-year-old man developed left middle and lower lobe pneumonia which did not respond to ampicillin (8 g daily) and gentamycin (120 mg daily). Parenteral administration of doxycycline (100 mg daily) was equally ineffective. However, the fever fell on administration of cefotiam (4 g daily). Antibody tests demonstrated Legionella pneumophila serogroup 1 as the causative organism. Because of the confined accommodation of the conscripts the source of the infection was thought to be the hot water system in the barracks. In two other policemen the demonstration of antibodies and of urine antigens confirmed Legionella infection as cause of an acute respiratory illness (Pontiac disease). Legionella pneumophila serogroup 1 subtype Philadelphia, 1-8 colony-forming units per ml, was isolated from six of 14 hot water samples in the barracks. This subtype possesses a virulence-associated antigen which is found in the majority of patient isolates of Legionella pneumophila serogroup 1.

Activated complement factors within the lung may induce several local biological effects. In order to investigate local complement activation we have developed non-competitive two-site ELISAs of C3a and total C3 in bronchoalveolar lavage fluid (BALF). For the assay of C3a, both C3 and C3(H2O) were removed from the samples by precipitation with polyethylene glycol. It was necessary to add carrier proteins to BALF to remove C3 and C3(H2O) fully. The ELISA of C3a has the lowest limit of detection reported thus far, namely 0.045 nM (= 0.405 ng/ml). In BALF from healthy persons (n = 9) the C3a concentration was 0.20 nM (0.12-0.31 nM) (median, range). C3a was higher in BALF from patients with asthma or with sarcoidosis; asthma (n = 10), 0.45 nM (0.20-5.79 nM); sarcoidosis (n = 19), 1.31 nM (0.095-5.65 nM) (Mann-Whitney U test, p less than 0.005). In BALF from patients with Pneumocystis carinii pneumonitis (n = 10) the C3a concentration was 0.18 nM (0.07-0.57 nM). C3a concentrations in BALF may reflect local complement activation in the lung and/or diffusion into the lumen. This was studied by normalizing C3a concentrations in BALF into values for epithelial lining fluid (ELF), and calculating serum-to-ELF quotients of C3a, and C3a/total C3 quotients.

We report the case of a 70-year-old man who was admitted to hospital A 66 days before developing Legionella pneumophila pneumonia 6 days after open heart surgery at hospital C. The strain of L. pneumophila recovered from the patient's sputum was of the same subtype (monoclonal antibody type, enzyme type, plasmid profile, and restriction endonuclease pattern) as a strain of L. pneumophila in the potable water supplied to the room where he stayed in hospital A. We conclude that the patient's respiratory tract became colonised by L. pneumophila while he was in hospital A and persisted for at least 63 days until he developed pneumonia requiring antibiotic treatment while in hospital C.

The authors show that application of anticipated postoperative intensive care gives the possibility ot obtain more complete effect of compensation. The basic components of this therapy are the following: removal of hypovolemia and anemia, combined (central and regional) anesthesia, prevention of pneumonia, normalization of salt and water exchange, removal of excessive catabolism, adequate ensuring of organism with energy and plastic material for long-time compensation, prophylaxis and treatment of paresis of digestive tract, chemoprophylaxis of wound infection. The proposed program of intensive therapy gives the possibility to minimize the lethality among wounded with penetrating abdominal gunshot injuries and can be used as a basic one for the development of various schemes of intensive therapy for other categories of wounds.

The detection of travel-associated legionellosis can be extremely difficult; hence, an extensive case investigation is recommended in pneumonia-striken travellers and tourists, who are particularly at risk of acquiring the disease. On the Island of Ischia (Isola d'Ischia, Naples, Italy) a total of six cases of Legionnaires' disease occurred from 1986 to 1990. All patients (one man and two women from Germany, one Austrian woman, one Swiss man, and one Italian woman) had taken thermal baths and stayed in local hotels; they all experienced severe pneumonia, and three of them died. These cases were associated with hotels, and the hot-water supply was presumed to have transmitted the infection. Remedial procedures were applied to the hot-water plumbing of the hotels according to the WHO recommendations and were proved to be effective. The occurrences described in this paper stress the importance of rapid and accurate reporting of diagnosed cases to the country where the infection was probably acquired, in order to ensure early detection of endemic foci and emerging clusters of legionellosis.

Inspired gases must be warmed and humidified during mechanical ventilation. In a prospective randomized study we compared the performance of a heated humidifier (HH) (Draegger Aquaport) and a heat and moisture exchanger (HME) (Pall Filter BB 2215). A total of 116 patients requiring mechanical ventilation (Servo 900 C Siemens) were enrolled into the study and were randomly assigned to 2 groups. Patients in group I were ventilated with a traditional breathing circuit with HH and patients in group II using a simplified circuit with HME. Pre-existing and hospital acquired atelectasis and pneumonia, occurrence of endotracheal tube (ET) occlusion and ventilatory parameters (respiratory rate, tidal volume) were studied. No statistical difference was found between groups for each parameter except the greater frequency of ET occlusions in the II group (0/61 vs 9/55) (p = 0.0008). Pall Filter (PF), a hydrophobic filter, humidifies the dry gases from the condensed water which is put down on the HME surfaces during cooling of saturated expired gases. This purely physical property is linked to the magnitude of the thermic gradient between the expired gases and the ambiant temperature. Performance impairment of PF in our study might be due to high ambiant temperature in the intensive care unit (usually around 28 degrees C) which reduces thermic gradient and water exchanges. We conclude that efficiency of PF may be weak in some conditions of ambiant temperature.

Gd-DTPA (Gd) enhanced Magnetic Resonance (MR) early images and delayed images of 28 patients with pulmonary or mediastinal tumors were analyzed and compared with the computed tomography scans and the plain MR images. Numbers of relative signal intensity of the tumors, secondary lesions (adjacent pneumonia or collapse) and pleural effusions were calculated and graphed on time intensity curves. Gd-enhanced MR early images were more useful than other methods in delineating viable areas from necrotic areas. However, Gd-enhanced MR delayed images better delineated margins of necrotic areas than Gd-enhanced MR early images did in some cases. In distinguishing tumors from secondary lesions, Gd-enhanced MR early images were the most useful, too. We considered Gd gradually penetrated into pleural effusions after intravenous administration, just in the same way into necrotic areas. Therefore pleural effusions showed very high intensity on Gd-enhanced MR delayed images. Time intensity curves of the tumors and pleural effusions showed characteristic patterns, but those of secondary lesions showed different patterns among the individual cases. We presumed this was due to the variances of the water and fibrous components among them.
