The objective of this study was to evaluate the etiological factors, diagnosis and therapy of pulmonary fungal infection in hematological malignancies, 14 cases of malignant hematological disease with pulmonary fungal infection were collected and analyzed. The results showed that 11 out of 14 cases had the respiratory manifestations, sputum was sticky and difficult to be expectorated in 7 cases, X rays in chests showed shadows with features of stigma and sheet in 11 cases, Candida albicans and aspergillus infection were observed in 10 and 2 cases respectively, the numbers of neutrophil were below 0.5 x 10(9)/L in 8 cases and below 1.0 x 10(9)/L in 3 cases respectively, fluconazole was used for 12 cases and clinical symptoms of 11 cases were improved within two weeks. In conclusion, the occurrence of pulmonary fungal infection in malignant hematological diseases is associated with intensive chemotherapy, decrease of neutrophil counts and using of broad-spectrum antibiotics, the diagnosis at early stage is difficult and clinicians should pay more attention to its clinical and laboratory examinations, and give them therapy in time.

Wegener's granulomatosis is a distinct form of necrotizing granulomatous vasculitis which usually affects the kidneys and the upper and lower respiratory tracts. Unusual manifestations have also been reported, and these include colitis, urethritis and diabetes insipidus. We describe a case of Wegener's granulomatosis which presented with rapidly progressive renal insufficiency, sudden deafness, red eye, facial palsy, and complicated by uncommon manifestations that were diffuse pulmonary hemorrhage and thrombotic thrombocytopenic purpura.

Invasive pulmonary aspergillosis is difficult to diagnose and a critical ill with high mortality. In this paper, the diagnosis and treatment of invasive pulmonary aspergillosis complicated in 3 cases of hematological malignancy (2 acute leukemias and 1 MDS-RA) were retrospectively analysed. All patients had histories of hypoimmunity and were received prophylactic antifungal treatment. Pulmonary aspergillosis infection still occurred and confirmedly diagnosed by sputum examination. After 7 to 14 days of combination treatment of liposomal amphotericin B, itraconazole and flucytosine, 2 cases were cured and another showed effective. In conclusion, early diagnosis and treatment of invasive pulmonary aspergillosis are very critical and the therapeutic effectiveness of combined scheme with liposomal amphotericin B, itraconazole and flucytosine is very effective for pulmonary aspergillosis.

OBJECTIVE: To analyze the clinical features of invasive fungal infection in patients with hematological malignancies and to compare the the therapeutic effect of fluconazole and intraconazole. METHODS: The clinical manifestations, mycological features, and the therapeutic results of 47 patients were retrospectively analyzed. Fluconazole was given to 17 paitents, intraconazole was given to 21 patients, and intraconazole to the other 9 patients after they had no effect with fluconazole. RESULTS: All patients had fever. The lung and the mouth cavity were the main locations of infection (53.2% and 21.3%, respectively). Fungi were found in 23 (48.9%) patients, in which the majority were Candida albicans and Aspergillus (56.5% and 26.1%, respectively). Intraconazole was more effective than fluconazole (63.3% vs. 34.6%, P<0.05) with no serious side effect. CONCLUSION The most common clinical features of IFI are fever, lung infection, and oral infection in patients with hematological malignancies. Candida albicans and Aspergillus infection are common. Intraconazole is safe and effective for invasive fungal infection.

OBJECTIVETo study the clinical effect and safety of high-frequency oscillatory ventilation (HFOV) combined with pulmonary surfactant (PS) in the treatment of neonatal severe meconium aspiration syndrome (MAS) complicated by neonatal pulmonary hemorrhage (NPH).

METHODSA total of 48 children with severe MAS complicated by NPH were enrolled, and a retrospective analysis was performed for the clinical effects of HFOV+PS (trial group, 25 children) and HFOV alone (control group, 23 children). The blood gas parameters, oxygenation index (OI), PaO/FiO(P/F) value, duration of pulmonary hemorrhage, ventilation time, length of hospital stay, incidence of complications, and outcome were compared between the two groups.

RESULTSAt 6, 12, 24, and 48 hours after treatment, the trial group had significantly better PaO, OI, and P/F value than the control group (P<0.05). Compared with the control group, the trial group had significantly shortened ventilation time and duration of pulmonary hemorrhage (P<0.05). There were no significant differences in the length of hospital stay, the incidence of complications, and cure rate between the two groups (P>0.05).

CONCLUSIONSHFOV combined with PS can better improve oxygenation function and shorten the duration of NPH and ventilation time. Meanwhile, it does not increase the incidence of adverse events. Therefore, it is a safe and effective therapy.

OBJECTIVE: To investigate the characters of infection in patients with malignant tumors, especially the distribution, yearly change of pathogens, and pathogen resistance to common antibacterial agents. METHODS: We respectively analyzed the characters of infection in 489 patients with malignant tumors. RESULTS: The respiratory tract was the most frequent infection site (61.1%). The infection was mainly caused by opportunistic pathogens. The Gram-negative bacterias mainly consisted of Pseudomonas aeruginosa, Escherichia coli, and Acinetobacter baumannii (46.3%). The Gram-positive bacteria mainly consisted of Staphylococcus aureus and Staphylococcus epidermidis (29.9%), and the rest 23.8% of the infection was caused by different fungi, mainly consisting of Candida albicans. The ratio of the Gram-negative bacteria resistance to antibiotics such as penicillins, cephalosporins (except ceftazidime), sulfanilamides, tetracyclines and quinolones was higher. The ratio of the Gram-positive bacteria resistance to antibiotics such as penicillins, macrolides and quinolones was higher. The ratio of fungus resistance to antibacterial agents such as fluconazol and itraconazole was higher. The infection caused by fungi obviously increased in the past 5 years. CONCLUSION The infection in patients with malignant tumors is mainly caused by opportunistic pathogens, and the pathogen resistance to antibacterial agents is serious. The infection caused by fungi is increasing.

Lymphocytic interstitial pneumonitis (LIP) is characterized by diffuse bilateral pulmonary infiltrations in both lower lobes. Pleomorphic lymphohistiocytes including mature lymphocytes, variable admixture of plasma cells and other mononuclear cells infiltrate within the pulmonary interstitium, ranging from widened septa to confluent masses. We report a case of LIP associated with Epstein-Barr virus in a patient with SLE and Sj gren's syndrome. A 50-year-old woman was admitted with insidious onset of progressive dyspnea for 20 days. She suffered from arthritis 10 years earlier without specific diagnosis. A radiography of chest has showed bilateral consolidative infiltrations with pleural effusion in both lower lung fields. Open lung biopsy documented lymphocytic interstitial pneumonitis which expressed Epstein-Barr virus genome in situ hybridization study. Following corticosteroid and cyclophosphamide therapy, clinical symptoms and radiologic infiltrations gradually remitted.
