Patient: Male, 61Final Diagnosis: AITL in Klinefelter syndromeSymptoms: —Medication: —Clinical Procedure: ChemotherapySpecialty: HematologyObjective:Rare diseaseBackground:Although patients with Klinefelter syndrome have elevated risk and incidence rates for several solid cancers, reports on the incidence of hematological malignancies have been equivocal.Case Report:We report a patient diagnosed with angioimmunoblastic T-cell lymphoma in whom Klinefelter syndrome was newly detected. Moreover, we discuss the development of a variety of lymphomas in patients with Klinefelter syndrome.Conclusions:This is the first case describing angioimmunoblastic T-cell lymphoma in a patient with Klinefelter syndrome who was treated with chemotherapy.

The purpose of this study was to investigate the differences in dietary intake, serum level and urinary excretion of taurine between the elderly with dementia and the normal elderly. Subjects with dementia were 22 (8 men, 14 women) and normal were 26 (2 men, 24 women). The general characteristics, anthropometric data were considered together. The blood and urine samples were obtained from the elderly in the morning fasting state. Taurine concentrations in serum and urinary excretion were determined using high performance liquid chromatography (HPLC). Dietary intake data were collected using questionnaires, and analyzed by Computer Aided Nutritional analysis program (CAN-pro 4.0). Statistical analyses were carried out using SPSS 20.0. There were no significant differences in age and BMI (body mass index) between the elderly with dementia and the normal elderly, however, blood total cholesterol, LDL cholesterol and HDL cholesterol levels of the elderly with dementia were relatively higher than the normal elderly. The elderly men with dementia took more lipid, riboflavin higher than the normal elderly men (P < 0.05). The elderly women with dementia took more nutrients except vitamin D, vitamin B and taurine than the normal elderly (P < 0.001). There were slight differences in serum taurine level between the two groups. However, urinary excretion of taurine in the elderly with dementia was significantly higher than the normal elderly (41.2%, P < 0.05).

H1-antihistamine is generally a well-tolerated and safe drug. However, in resemblance with all other drugs, H1-antihistamines can also prompt adverse drug reactions (ADRs). We recently encountered the very unusual ADR of H1-antihistamine-induced gynecomastia. A 21-year-old man with idiopathic anaphylaxis was treated with ebastine (Ebastel), a second-generation H1-antihistamine, for the prevention of anaphylaxis. Three months later, the patient remained well without anaphylaxis, but had newly developed gynecomastia. Because anaphylaxis recurred after the cessation of H1-antihistamine, the preventive medication was changed to omalizumab. A few months later, his gynecomastia had entirely disappeared. Physicians should be aware of this exceptional ADR of H1-antihistamine.

This study investigated the associations between dietary history of past taurine intake and cognitive function in the elderly. Subjects of this study were 40 elderly persons with dementia (men 14, women 26) and 37 normal elderly persons (men 5, women 32). Data were collected using questionnaires by investigator-based interview to the elderly and family caregivers. We examined their general characteristics, anthropometric data, cognitive function, and taurine index. Cognitive function was measured using MMSE-DS and higher score means better cognitive function. As dietary history of past taurine intake, taurine index was evaluated by scoring the intake frequency of 41 kinds of taurine-containing foods. Part correlation analysis (sex, age, and school educational period correction) was used to analyze associations between taurine index and cognitive function. The analysis of all data was carried out by the SPSS 20.0 program for windows. The age, height, weight, and BMI of elderly with dementia showed no statistical significance compared to normal elderly. The elderly with dementia had significantly higher school education period (7.4 years) than the normal elderly (4.8 years) (p < 0.01). Nevertheless, the average total score of cognitive function (MMSE-DS) of the elderly with dementia (18.1 points) was significantly lower than score of the normal elderly (21.7 points) (p < 0.05). The average taurine index of the elderly with dementia (104.7 points) was significantly lower than average taurine index of the normal elderly (123.7 points) (p < 0.01). There were positive correlations between total taurine index and total score of cognitive function in all the elderly subjects (p < 0.05). In particular, as taurine index was higher, there were significantly higher scores of cognitive function such as 'time orientation' and 'judgement and abstract thinking' (p < 0.01). In conclusion, these results suggest that past taurine intake may have a positive effect on present cognitive function in the elderly.
