The case of a 59-year-old man with granulomatous glossitis is presented. The patient complained of increasing swelling of his tongue for years and a recent onset of perioral edema. Because of sarcoid-like granulomas found in a first lingual biopsy specimen, the disease was initially misdiagnosed as a localized form of sarcoidosis. A second biopsy specimen(More)
We report on the case of a 51-year-old female patient who had been suffering from multiple itching nodules for 3 years. Some of these lesions were classified clinically and histologically as keratoacanthomas (KA), whereas the multiple smaller nodules were found on histological examination to be either early stage KA or lesions of prurigo simplex subacuta.(More)
Due to the high risk of amputation they involve, diabetic neuropathic plantar ulcers (DNPU) must be regarded as a late manifestation/complication of diabetes mellitus. The suspected cause of these ulcers--disturbed cutaneous microcirculation--was studied by simultaneously measuring laser-Doppler flux (LDF) and cutaneous oxygen tension (pCUO2) in 14 patients(More)
SYA013, a homopiperazine analog of haloperidol, was further evaluated for antipsychotic potential using additional animal models. Previously, SYA013 was tested in mice with an antipsychotic screening model in which it inhibited apomorphine induced climbing behavior, indicating antagonism of the dopaminergic system and the potential for use in the treatment(More)
Functional tests simulating local stresses are especially suitable for the evaluation of physiological and pathophysiological patterns in the cutaneous microcirculation, particularly if combined with non-invasive methods such as laser-Doppler fluxmetry and oxygen tension measurements. Arterial occlusion (3 min) and local heating (up to 42 degrees C) are(More)
Necrobiosis lipoidica (NL) is a chronic, skin disease usually localized pretibially and often associated with diabetes mellitus. Primary vascular disturbances are considered pathogenetic for NL. In order to determine microcirculatory alterations in "idiopathic" NL linked with neither arterial hypertension nor diabetes mellitus, we performed simultaneous(More)
