Invasive fungal infection (IFI) causes morbidity and mortality among patients with hematological malignancies who receive cytotoxic chemotherapy or hematopoietic stem cell transplantation (HSCT). We evaluated the incidence and treatment outcomes of proven and probable IFI in 22 institutions between 2006 and 2008 following the recent European Organization for Research and Treatment of Cancer/Mycosis Study Group (EORTC/MSG) consensus criteria. We analyzed 2,821 patients with hematological malignancies, including 597 who had undergone HSCT; these included patients with acute leukemia (n = 697), myelodysplastic syndrome (n = 284), lymphoma (n = 1465), or multiple myeloma (n = 375). IFIs were diagnosed in 38 (1.3%) patients (18 proven and 20 probable), including 20 patients who underwent HSCT and 18 who received chemotherapy alone; these included patients with aspergillosis (n = 23), candidiasis (n = 6), mucormycosis (n = 6), trichosporonosis (n = 2), and geotrichosis (n = 1). The incidence of IFI was 5.4 % in allogeneic HSCT patients, 0.4 % in autologous HSCT patients, and 0.8 % in patients receiving chemotherapy alone. Eighteen patients with aspergillosis were diagnosed with probable pulmonary IFI as determined by computed tomography scan and positive galactomannan assay. Overall, antifungal targeted therapies resulted in successful outcomes in 60.0 % of patients. IFI-attributable mortality rate was higher in HSCT patients than in those receiving chemotherapy alone, but the difference was not statistically significant.

TAKEUCHI, T., et al.: A Case of a Short‐Coupled Variant of Torsades De Pointes with Electrical Storm. This case report describes a short‐coupled variant of Torsades de Pointes with a characteristic ECG pattern consisting of a prominent J wave in leads V3–V6, in which an electrical storm was evoked with autonomic receptor stimulation and a blockade test. The patient's frequent VF attacks were triggered by short‐coupled premature ventricular contractions with a right bundle branch block morphology and left‐axis deviation, and were suppressed by deep sedation followed by a combination therapy using verapamil and mexiletine. Interestingly, with the use of those drugs, the prominent J wave diminished. The mechanism underlying this syndrome is discussed. (PACE 2003; 26[Pt. I]:632–636)

Peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) comprises a group of heterogeneous lymphomas that do not fit any other identified PTCL-subgroup and show poor prognosis. To clarify clinical aspects of Japanese PTCL-NOS patients, the Hokkaido Hematology Study Group conducted a multicenter retrospective analysis. The median age of the 107 patients (male 65.4 %) was 67 years. The majority (82.4 %) had stage III/IV disease. Following the international prognostic index, 65.7 % were categorized as high intermediate or high risk. Primary chemotherapy was selected in 96 (90 %) patients, 86 of whom received anthracycline regimens. Sixteen patients received high-dose chemotherapy with autologous stem cell transplantation. Forty-eight (52 %) of the 92 evaluable patients achieved complete remission (CR) or CR/unconfirmed after the primary treatment, in which 22 (46 %) relapsed. The estimated 5-year overall survival (OS) of all patients was 35 %. Three independent risk factors (RFs) associated with OS, bulky disease (hazard ratio HR = 5.324; p = 0.019), age>60 years (HR = 3.015; p = 0.025), and platelet count less than 10 × 10(4)/μL (HR = 3.999; p = 0.036), were identified in a multivariate analysis. Using these three RFs, the OS curves were significantly stratified into three risk groups (low risk, 0 RFs, 3-year-OS 72 %; intermediate risk, one RF, 30 %; high risk, two or three RFs, 0 %; p = 0.0005). These findings may provide valuable information for the management of Japanese PTCL-NOS patients.

A 65-year-old Japanese man complaining of general malaise and presenting with high fever was admitted to our hospital. He had untreated diabetes and hepatocellular carcinoma with liver cirrhosis. Overall findings of the patient indicated sepsis. Two blood cultures were positive for Streptococcus dysgalactiae, a group C or G Streptococcus. Transthoracic and transesophageal echocardiography revealed vegetations on the aortic and mitral valves. Although antimicrobial therapy with aminobenzyl penicillin was effective for controlling infection, multiple cerebral embolisms occurred in the clinical course of the disease. Primary care doctors should consider invasive Streptococcus dysgalactiae infections when treating elderly patients with underlying diseases, and Streptococcus dysgalactiae should be included in the list of microorganisms considered to cause endocarditis in such patients.
