Japanese Versus Non-Japanese Patients with Transient Ischemic Attack or Minor Stroke: Subanalysis of TIA registry.org

BackgroundTIAregistry.org is an international cohort of patients with transient ischemic attack (TIA) or minor stroke within 7 days before enrollment in the registry. Main analyses of 1-year follow-up data have been reported.⁵ We conducted subanalysis on the baseline and 1-year follow-up data of Japanese patients.MethodsThe patients were classified into 2 groups based on Japanese ethnicity, Japanese (345) and non-Japanese (3238), and their baseline data and 1-year event rates were compared. We also determined risk factors and predictors of 1-year stroke.ResultsCurrent smoking, regular alcohol drinking, intracranial arterial stenosis, and small vessel occlusion; and hypertension, dyslipidemia, coronary artery disease, and extracranial arterial stenosis were more and less common among Japanese patients, respectively. Stroke risk was higher and TIA risk was lower at 1-year follow-up among Japanese patients. The baseline risk factors for recurrent stroke were diabetes, alcohol drinking, and large artery atherosclerosis. Independent predictors of 1-year stroke risk were prior congestive heart failure and alcohol consumption.ConclusionsThe two populations of patients featured differences in risk factors, stroke subtypes, and outcome events. Predictors of recurrent stroke among Japanese patients included congestive heart failure and regular alcohol drinking. Strategies to attenuate residual risk of stroke aside from adherence to current guidelines should take our Japanese-patient specific findings into account.     

A case of drug eruption induced by hydroxyzine pamoate]

A 62-year-old woman with rheumatoid arthritis, Basedow's disease and arrhythmia has been treated with antirheumatic, antiarrhythmic drugs and so on. She developed pruritic diffuse erythema with papules on the trunk and extremities 2 days after taking hydroxyzine pamoate for asteatotic eczema. Laboratory data showed increased levels of eosinophils. Histopathological examination revealed a infiltrate of inflammatory cells in the upper dermis. Patch tests with hydroxyzine pamoate and hydroxyzine hydrochloride were positive. From these findings, we diagnosed this case as drug eruption due to hydroxyzine. Her eruption subsided after she discontinued hydroxyzine pamoate and other drugs which were started within 5 days before the onset of the eruption and was treated with systemic steroid, systemic antiallergic drug and topical steroid.     

Case Report: Gianotti-Crosti Syndrome Associated with Human Herpesvirus-6 Infection

We report a case of Gianotti-Crosti syndrome associated with human herpesvirus-6 (HHV-6) infection. An eight-month-old girl developed monomorphous papules on her cheeks, buttocks, and extremities after the subsidence of exanthema subitum. Viral antibody analysis confirmed primary HHV-6 infection. HHV-6 may be added to the list of causative agents of Gianotti-Crosti syndrome.     

Coagulopathy in disseminated intravascular coagulation due to abdominal sepsis: determination of prothrombin fragment 1 + 2 and other markers.

To estimate the degree of coagulopathy in abdominal sepsis, we measured the plasma levels of prothrombin fragment 1 + 2 (F1 + 2), thrombin-antithrombin III complex (TAT) and plasmin-alpha 2-plasmin inhibitor complex (PIC) by the enzyme-linked immunosorbent assay in 38 patients with disseminated intravascular coagulation (DIC). In 20 patients with DIC due to abdominal sepsis, plasma levels of F1 + 2, TAT and PIC were 2.6 nmol/l, 27.9 micrograms/l and 1.5 micrograms/ml, respectively, with a mean antithrombin III (AT III) activity of 41.7%. F1 + 2, TAT, PIC and AT III levels were 4.7 nmol/l, 75.8 micrograms/l, 8.8 micrograms/ml and 70.9% in 18 patients with DIC as the result of malignancy. Though AT III levels in DIC due to sepsis were lower than those in DIC due to malignancy, the levels of F1 + 2, TAT and PIC in the former were not significantly more increased than those in the latter. The plasma levels of F1 + 2 were positively correlated with TAT and PIC in DIC patients with malignancy; however, there was no correlation between F1 + 2 and TAT or PIC in DIC patients with sepsis. In addition, the levels of serum albumin in the two groups were similar. These results suggest that activation of coagulation and fibrinolytic systems may not be so prominent in cases of DIC due to abdominal sepsis, compared to related events in DIC due to malignancy. It is also suggested that the depletion of AT III in cases of sepsis is not only caused by a consumption related to intravascular coagulation or to an alternate distribution of protein.(ABSTRACT TRUNCATED AT 250 WORDS)
