1/68. Spontaneous remission in myelodysplastic syndrome.

    A 73-year-old man was admitted for investigation of pancytopenia. His physical examination was unremarkable and the bone marrow aspirate was compatible with myelodysplastic syndrome (RAEB). cytogenetic analysis of the bone marrow revealed a trisomy 21. The patient received transfusions of packed red cells, and his condition remained stable for the next 7 months. He was then admitted with a chest infection and was treated with broad-spectrum antibiotics with satisfactory response. During his hospitalization there was a gradual increase in his complete blood count values, which persisted, resulting in a normal peripheral blood after 3 months. A bone marrow aspirate performed at that time revealed normal findings with no karyotypic abnormalities, indicating a spontaneous remission. The patient remained stable for the next 6 months; then he recurred with 20% blasts in his bone marrow and reappearance of trisomy 21 in 42% of the metaphases examined. Several hematologic malignancies with spontaneous remissions have been described to date, but they have generally been short and recurrence is the rule, as in the case described. The role of endogenous cytokines in triggering these spontaneous remissions is under question, as the exact mechanism is unknown.

2/68. Pneumonitis secondary to the influenza vaccine.

    We report a 58-year-old man who developed respiratory distress and interstitial shadowing on chest X-ray 10 days after receiving the influenza vaccine. He failed to respond to intravenous antibiotics but his clinical condition, hypoxia and chest X-ray changes improved dramatically on oral steroids. The clinical diagnosis was pneumonitis secondary to recent influenza vaccination.

3/68. Acid fast filaments in stool samples from an AIDS patient.

    The presence of filamentous bacteria morphologically similar to Nocardia in a fresh stool sample from an AIDS patient with pulmonary nocardiosis is here reported. The material was submitted to our laboratory for a parasitologic examination and was stained by the Kinyoun method, revealing numerous delicate, irregularly stained, branching acid-fast filaments. nocardia asteroides had been isolated from sputum samples of this patient. The patient was a 32 year-old hiv female admitted to our center on June 1997 because of productive cough, right-sided thoracic pain and weight loss. Chest X rays showed the presence of right superior lobe excavated pneumonia. This was the first time we had observed filamentous bacteria similar to Nocardia in a stool sample submitted to parasitologic examination. For similar cases, and when its presence was not detected in other specimens collected from the same patient, intestinal endoscopy and biopsy should be performed for eventual lesions and smear examination repeated with Kinyoun stain and cultures for Nocardia.

4/68. 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.

5/68. Pulmonary infiltrates in an elderly man.

    An 80-year-old man presented with subjective fever, chronic cough occasionally producing scant yellow sputum, retrosternal pleuritic pain, and dyspnea on walking one block. Since symptom onset three months earlier, he had lost 20 pounds; he had had two loose stools a day, fatigue, malaise, and anorexia but not hemoptysis, nausea, vomiting, hematemesis, hematochezia, or melena. He denied paroxysmal nocturnal dyspnea or orthopnea. As far as could be ascertained, he not recently been exposed to tuberculosis or any other infectious disease. He had previously been seen at another clinic and had completed a 10-day trial of erythromycin (500 mg p.o. q12 h) without apparent change in symptoms.

6/68. Nosocomial pneumonia likely caused by stenotrophomonas maltophilia in two patients with polymyositis.

    We report two cases of polymyositis (PM) complicated with nosocomial pneumonia probably caused by stenotrophomonas maltophilia, which was resistant to multiple antimicrobials. In the first case, the chest CT findings and high serum endotoxin level as well as sputum culture results were helpful for the proper diagnosis and the therapy was successful. However the second patient died of a lung abscess in spite of the intensive antibiotic therapy. When PM patients develop pneumonia unresponsive to various antibiotics, a multi-drug-resistant bacteria such as stenotrophomonas maltophilia should be considered as the pathogen.

7/68. Legionella pneumonia from a novel industrial aerosol.

    After a worker from a plastics factory was diagnosed with legionella pneumonia it was learnt that a retired employee at the factory had been in hospital with a serious chest infection six months before and legionella pneumonia was diagnosed in retrospect from stored serum. The likeliest common source was a machine cooling system that took water from an uncovered water tank outdoors (from which legionella pneumophila was isolated) and which generated an aerosol through a crack in the flow meter sight glass.

8/68. Fatal disseminated Nocardia farcinica infection in a renal transplant recipient.

    Six years after a renal cadaver transplant, a 20-year-old girl developed multiple painful cutaneous abscesses and bilateral pneumonia secondary to Nocardia farcinica infection. Despite broad in vitro sensitivity to several antibiotic agents and aggressive medical treatment, the patient failed to respond and died after 10 weeks of therapy. We conclude that Nocardia farcinica is a very aggressive organism in immunocompromised patients and is often resistant to antimicrobial agents.

9/68. Histopathologic features of burkholderia cepacia pneumonia in patients without cystic fibrosis.

    We present the histopathologic features of fatal burkholderia cepacia pneumonia in three adults (one man [age 44 years] and two women [aged 40 and 43 years]). In all patients, the pulmonary infiltrates initially were localized (right middle lobe, left upper lobe, and right middle lobe) but rapidly progressed. Two open-lung biopsies and one pneumonectomy specimen showed necrotizing granulomatous inflammation merging with areas of more conventional necrotizing bronchopneumonia In one patient, a mediastinal lymph node also showed stellate necrotizing granulomas. vasculitis was absent. B. cepacia was cultured from the open-lung biopsies and bronchial wash specimens in two patients and from postmortem cultures of lung, subcarinal lymph nodes, and blood in the third. The histopathology in these patients resembles that of melioidosis, which is caused by a related organism, burkholderia pseudomallei. B. cepacia needs to be considered in the differential diagnosis of necrotizing granulomatous inflammation. In addition, given the rarity with which B. cepacia is identified as a cause of pneumonia in the immunocompetent host, isolation of B. cepacia should trigger a workup for underlying immunodeficiency or lead to an investigation to exclude the possibility of a nosocomial infection.

10/68. Report on five cases of tularaemic pneumonia in a tularaemia outbreak in spain.

    A report is given on five cases of atypical tularaemic pneumonia selected from among 140 cases of tularaemic infection in a previously reported outbreak occurring in 1997. Prior to this outbreak no human cases of tularaemia had been reported in spain. All cases were diagnosed serologically. All five patients reported on here had a mild form of the disease, which was treated successfully with streptomycin in four cases and ciprofloxacin in one case. Tularaemic pneumonia should be considered in the differential diagnosis of atypical pneumonia in spain, especially in hunters and other persons who handle animal carcasses.
