AIMS Psychiatric comorbidity and mental instability seem to be important unfavorable prognostic factors for long-term psychosocial adjustment in gender identity disorder (GID). However, psychiatric comorbidity in patients with GID has rarely been assessed. In this study, we investigated the psychiatric comorbidity and life events of patients with GID in(More)
The aim of this study was to examine the clinical characteristics of patients with gender identity disorder (GID) at a GID clinic in Japan. A total of 603 consecutive patients were evaluated at the GID clinic using clinical information and results of physical and neurological examinations. Using DSM-IV criteria, 579 patients (96.0%) were diagnosed with GID.(More)
We describe a patient with natural killer (NK)/T cell lymphoma who relapsed after autologous peripheral blood stem cell transplantation (auto-PBSCT) and was successfully treated with Escherichia coli (E. coli) and Erwinia L-asparaginase. A 38-year-old male patient with ulcerated tumor at the left thigh was diagnosed as having nasal type NK/T cell lymphoma(More)
The normal counterparts of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) have not been accurately identified. We immunohistochemically analyzed 10 PTCL-NOS cases to examine the expression of the master regulators of T-cell differentiation and of surface antigens, including chemokine receptors. All cases were positive for the master(More)
BACKGROUND Primary lymphomatous effusion is a rare lymphoma that arises in the body cavity and has a peculiar proliferative form, lacking a tumor. This primary lymphomatous effusion includes human herpes virus 8 (HHV8)-related primary effusion lymphoma (PEL) and HHV8-unrelated PEL-like lymphoma. We attempted to clarify the nature of the primary lymphomatous(More)
Biphenotypic acute leukemia co-expressing T-lymphoid and myeloid markers is rare, accounting for less than 1% of acute leukemias. However, several clinical characteristics including male predominance, frequent lymphadenopathy and unfavorable outcome have been identified. Recurrence of monosomies 7p and/or 12p in T/myeloid biphenotypic acute leukemia has(More)
AIMS De novo CD5-positive diffuse large B cell lymphoma (CD5+DLBL) is a subtype of DLBL with poor clinical outcome. To investigate the cytogenetic pathogenesis of CD5+DLBL, we analyzed the chromosomal findings of 18 patients with CD5+DLBL. METHODS Tumor cells were cultured and metaphase was captured by colchicine exposure. Using trypsin-Giemsa banding,(More)
Prior 8-week treatment with menatetrenone, MK-4, followed by 8-week risedronate prevented the shortcomings of individual drugs and significantly increased the strength of ovariectomized ICR mouse femur compared to the ovariectomized (OVX) controls. Neither MK-4 following risedronate nor the concomitant administration may be recommended because they brought(More)
To investigate the biological mechanism of gender identity disorder (GID), five candidate sex hormone-related genes, encoding androgen receptor (AR), estrogen receptors alpha (ERalpha) and beta (ERbeta), aromatase (CYP19), and progesterone receptor (PGR) were analyzed by a case-control association study. Subjects were 242 transsexuals (74 male-to-female(More)
We studied the incidence of t(14;18)(q32;q21) in 54 patients with follicular lymphoma (FL) by dual-color fluorescence in situ hybridization on paraffin-embedded tissue sections (tissue-FISH) using probes for BCL2 and immunoglobulin heavy chain (IGH) genes. The t(14;18) was detected in 28 (56%) of 50 patients, who were successfully analyzed. On the other(More)
