Little is known about the clinicopathologic char− acteristics of primary follicular lymphoma of the gastrointestinal tract (PFLGI). We report our ex− perience with double−balloon enteroscopy (DBE) in patients with PFLGI. Between January 2001 and December 2006, thirteen patients with PFLGI (nine men and four women; mean age, 53.4 years) visited Hiroshima University Hospital. We performed DBE in 11 PFLGI patients to examine the entire small bowel. DBE showed new lesions in the third portion of the duodenum, jejunum, or ileum in nine of these 11 patients (81.8 %). The en− doscopic finding was nodularity of the involved mucosal surface (small whitish polyps or whitish granules). Seven patients were treated with ri− tuximab plus CHOP chemotherapy (R−CHOP). A complete response was obtained in all patients who received R−CHOP, and no recurrence was seen (mean follow−up period, 22.5 months).

3D-HyCoSy provided advantages of better assessment of uterine cavity over XHSG. Compared with conventional XHSG, the efficacy of 3D-HyCoSy to assess tubal patency was acceptable. In addition, the procedure of 3D-HyCoSy appears to be better tolerated, requiring no sedation or anesthesia and a reduced examination time. Thus, 3D-HyCoSy with saline as a contrast medium is feasible and could comprise a routine outpatient procedure in the initial evaluation of infertile women.

Sympathetic ophthalmia (SO) is very rare but it remains one of the most intractable eye diseases. In clinical manifestations and histopathologic features SO is known to resemble closely Vogt-Koyanagi-Harada's disease (VKH disease). We had reported that VKH disease was significantly associated with HLA-DRB1*04 and -DQB1*04 in Japanese patients. In this study, to investigate an HLA association with SO we performed HLA serological and PCR-based DNA typing in 16 patients and 50 healthy controls. Our study revealed that HLA-DRB1*04 (0405; Pc < 5 x 10(-4)), DQA1*03 (Pc < 5 x 10(-3)), and DQB1*04 (0401; Pc < 5 x 10(-4)) were significantly associated with SO as compared to the healthy controls but there was no significant difference in the frequencies of any DPB1 alleles between the patients and healthy controls. It can be postulated that not only the clinical manifestations but also the genetic predisposition of SO are very similar to those of VKH disease.

Subclinical thyroid disease and even variations in thyroid function within the normal range is associated with cognitive function and a risk of Alzheimer disease (AD). Several studies reported the effect of thyroid hormones on cerebral blood flow. The aim of this study was to objectively evaluate regional cerebral blood flow (rCBF) in association with thyroid hormone levels within the normal range in patients with AD. Serum thyroid-stimulating hormone (TSH), free T3, and free T4 levels were measured in 62 patients with AD (23 men and 39 women; age 56 to 91 y; mean age 77.3 y) and 27 control subjects (9 men and 18 women; age 61 to 93 y; mean age 75.8 y). The 99mTc ethylcysteinate dimer single photon emission computed tomography was performed in all subjects. The rCBF in the region of interest was measured by the noninvasive Patlak plot method and calculated using FineSRT, which is a fully automated region of interest technique. No significant correlation was found between thyroid hormone levels and Mini-Mental State Examination scores or global CBF values. Serum levels of TSH, but not free T3 or free T4, were significantly inversely correlated with rCBF in the middle and inferior temporal regions of right cerebral hemisphere in patients with AD. Control subjects showed no significant correlation between thyroid hormone levels and rCBF. Although these findings of a regional relationship must be considers preliminary, this study proposed the hypothesis that altered TSH levels within the normal range may be related to brain perfusion in right temporal region.
