An autopsy case of Ph1--positive acute lymphoblastic leukemia with disseminated infection of Fusarium solani

A 56-year-old woman with Ph1--Positive acute Lymphoblastic Leukemia was admitted to our hospital for induction chemotherapy in June 1999. The patient was presented with a central scotoma of left eye during treatment course and was given diagnosis of endophthalmitis. Thereafter she also developed skin induration and suffered from serious pneumonia. Amphotericin B administration was started because of high titer of beta-D-glucan, but soon discontinued due to its adverse effect. Blood cultures yielded colonies of fungus and it was identified Fusarium solani. Her general condition deteriorated with progression of pneumonia, and she died of respiratory insufficiency. Autopsy was performed, and its specimen revealed the disseminated infection of Fusarium solani (lung, eye, heart, kidney and skin). We should pay special attention to the fusariosis in Japan also.

Current status of hybrid intravascular ultrasound and optical coherence tomography catheter for coronary imaging and percutaneous coronary intervention

Both intravascular ultrasound (IVUS) and optical coherence tomography (OCT) play a crucial role in elucidating the pathophysiology of coronary artery disease (CAD) with the goal to improve patient outcomes of medical and/or interventional CAD management. However, no single intravascular imaging technique has been proven to provide complete and detailed evaluation of all CAD lesions due to some limitations. Although sequential use of multiple modalities may sometimes be performed, there may be issues related to risk, time, and cost. To overcome these problems, several hybrids involving dual-probe combined IVUS-OCT catheters have been developed.The aim of this review article is to demonstrate some limitations of stand-alone imaging devices for evaluation of CAD, summarize the advances in hybrid IVUS-OCT imaging devices, discuss the technical challenges, and present the potential value in the clinical setting, especially in patients receiving medical or interventional CAD management.     

Increased DNA-incorporated thiopurine metabolite as a possible mechanism for leukocytopenia through cell apoptosis in inflammatory bowel disease patients with NUDT15 mutation

Journal of Gastroenterology - Polymorphisms in the nucleotide diphosphate-linked moiety X-type motif 15 (NUDT15) gene are associated with thiopurine-induced leukopenia in patients with inflammatory...     

A Japanese patient with familial Mediterranean fever associated with compound heterozygosity for pyrin variant E148Q/M694I

Familial Mediterranean fever (FMF) is an inherited inflammatory disease occurring mainly in Mediterranean and Middle Eastern populations. FMF is caused by mutations in the MEFV gene that encodes pyrin/marenostrin. Here, we report a Japanese female FMF patient with heterozygosity for the compound pyrin E148Q/M694I showing recurrent fever, serositis or delay in skin wound healing. Her father and elder sister were heterozygous for pyrin variant M694I alone and sometimes suffered from mild fever or delay in wound healing, but her mother was heterozygous for pyrin variant E148Q alone and had no symptoms. This suggested that the inheritance of FMF occurred not only in an autosomal recessive manner but also in an autosomal dominant manner in this Japanese family, and the severity of the disease differed among the family members in relation to the mutation. In the treatment of FMF, colchicine, reserpine or prazosin hydrochloride have been reported to prevent the attacks, but, in our patient such drugs were ineffective or caused side effects, and only the anti-allergic drug azelastine was of benefit in relieving the attacks.

Management for traumatic chronic subdural hematoma patients with well‐controlled shunt system for hydrocephalus

Traumatic CSDH enlarged in two cases with VP or LP shunt system although the shunt valve pressure was increased to 200 mmH₂O. In surgery, the hematoma cavity pressure was found to be 130 and 140 mmH₂O, suggesting that to raise the shunt valve pressure is not effective for decreasing CSDH volume.
