Context: Stroke increases the risk of subsequent hip fracture by.2 to 4 times. Hy.erhomocy.teinemia is a risk factor for both ischemic stroke and osteoporotic fractures in elderly.men and women. Treatment with folate and mecobalamin (vita min B12) may.improve ***: To investigate whether trea tment with folate and vitamin B12 reduces the incidence of hip fractures in pati ents with hemiplegia following ***, Setting, and Patients: A double-b lind, randomized controlled study.of 628 consecutive patients aged 65 y.ars or o lder with residual hemiplegia at least 1 y.ar following first ischemic stroke, w ho were recruited from a single Japanese hospital from April 1, 2000, to May.31, 2001. Patients were assigned to daily.oral treatment with 5 mg of folate and 15 00 μg of mecobalamin,or double placebo; 559 completed the 2-y.ar *** in Outcome Measure: Incidence of hip fractures in the 2 patient groups during th e 2-y.ar follow-up. Results:At baseline, patients in both groups had high leve ls of plasma homocy.teine and low levels of serum cobalamin and serum folate. Af ter 2 y.ars, plasma homocy.teine levels decreased by.38%in the treatment group and increased by.31%in the placebo group (P y.ars was 10 and 43 for the treatment and placebo groups, re spectively.P y. No significant adverse effects were repo rted. Conclusion: In this Japanese population with a high baseline fracture risk , combined treatment with folate and vitamin B12 is safe and effective in reduci ng the risk of a hip fracture in elderly.patients following stroke.

Background: We recently.proposed that certain palmoplantar epidermoid cy.ts may.be related to eccrine ducts and that human papillomavirus (HPV) 60 may.play.a role in their pathomechanism. However, the origin of palmoplantar epidermoid cy.ts is still controversial. Objectives: To examine the contribution of eccrine ducts and HPV 60 in the development of epidermoid cy.ts. Methods: Five epidermoid cy.ts and four ridged warts that had developed on the soles of a patient were studied histologically. immunohistochemically.and by.DNA- DNA in situ hy.ridization. Using serial sections obtained from its entire body. a three- dimensional reconstruction (3DR) analy.is was performed on the smallest cy.t to analy.e the relationship between the epidermoid cy.t, eccrine duct and the overly.ng epidermis. Results: Histological and DNA- DNA in situ hy.ridization analy.es demonstrated both homogeneous intracy.oplasmic inclusion bodies pathognomonic for HPV 60 infection and HPV 60 DNA sequences not only.in all of the epidermoid cy.ts and ridged warts but also in the acrosy.ingeal portion of an eccrine duct, with the dermal portion of which the smallest cy.t had been revealed to connect by.3DR analy.is. However, immunohistochemical analy.es using antibodies against human carcinoembry.nic antigen(CEA),involucrinand several cy.okeratins (CKs) revealed that the immunoreactivity.of the cy.t was not identical to that of the eccrine dermal duct but was identical to that of suprabasal lay.rs of the epidermis. Conclusions: It was clearly.demonstrated that an HPV 60associated epidermoid cy.t with immunoreactivities for CEA, involucrin and CKs which were identical to those of the epidermis connected with the eccrine dermal duct, supporting the idea that certain palmoplantar epidermoid cy.ts may.develop following the epidermoid metaplasia of eccrine ducts with HPV 60 infection.

We study.the dy.amic of scalar bosons in the presence of Aharonov-Bohm magnetic field. First, we give the differential equation that governs this dy.amic. Secondly. we use variational techniques to show that the following Schrödinger-Newton equation: , where A is an Aharonov-Bohm magnetic potential, has a unique ground-state solution.
