The action of riluzole, a neuroprotective drug, on cloned delayed rectifier K+ channels (Kv1.5 and Kv3.1) was examined using the whole-cell patch-clamp technique. Riluzole reversibly inhibited Kv1.5 currents in a concentration-dependent manner with an IC50 of 39.69+/-2.37 microM. G-protein inhibitors (pertussis toxin and GDPbetaS) did not prevent this(More)
The neurological system plays an important role in modulating some inflammatory skin diseases. Neuro-cutaneous interactions may be mediated by the release of neuropeptides such as substance P (SP) which activate immunocompetent cells in the skin by binding to high affinity neurokinin receptors (NKR). Since epidermal keratinocytes produce a variety of(More)
Kikuchi-Fujimoto disease commonly presents with cervical lymphadenopathy accompanied by fever, myalgia, neutropaenia, and rarely cutaneous eruption. Most cutaneous lesions present as erythematous macules, papules, plaques, nodules, or ulcers on the upper part of the body such as trunk, upper extremities, and face. We present a case of Kikuchi-Fujimoto(More)
The common clinical presentations of herpes simplex virus (HSV) and molluscum contagiosum (MC) are well known to dermatologists. However, folliculitis due to these viruses is an infrequently reported entity and might be considered a sign of immunosuppression [such as infection with human immunodeficiency virus, (HIV)], especially in cases of folliculitis(More)
Cases of pseudolymphoma induced by intradermal gold injection or gold piercing have previously been described. Most of these cases showed the histopathological finding of B-lymphocyte predominant lymphocytoma cutis. We describe a patient with gold acupuncture-induced T-cell-rich pseudolymphoma. Some T cells showed positive staining with CD30. The lesions(More)
BACKGROUND Lichenoid keratosis (LK) is a rather frequent skin lesion that has some histologic features similar to lichen planus (LP). The clinical and histopathologic characteristics of LK and differential tools from LP are not yet fully established. OBJECTIVE The purpose of this study was to investigate the clinical and histopathologic characteristics of(More)
Fas is a well-known cell surface receptor whose main function is the induction of apoptosis in many cell types including human keratinocytes. Several reports indicate that anti-Fas antibody can induce apoptosis in cultured keratinocytes after interferon gamma (IFN gamma) pretreatment. Because IFN gamma is synthesized by activated T cells, but not by(More)
OBJECTIVE To report a case of serotonin syndrome associated with interaction between fentanyl and citalopram, as evidenced by medication history, clinical features and reversal following discontinuation of fentanyl. CASE SUMMARY A 65-year-old patient chronically treated with the selective serotonin reuptake inhibitor (SSRI) citalopram developed confusion,(More)
We describe four cases of pustulotic arthro-osteitis. All of them suffered from anterior chest wall symptoms, such as swelling and pain on the sternoclavicular joint, sternal angle area, sternocostal joint, and costochondral junction. Although chest X-ray findings were all normal, 99mTc-scintigraphy revealed increased uptake in the affected areas in all(More)
