dermatitis artifacta is a factitious dermatological disorder with many forms of presentation of self inflicted skin lesions in any part of the body. dermatitis artefacta is a difficult condition for diagnosis and treatment mostly because of the patient's denial. the liaison among primary care physicians, psychiatrists and dermatologists can be important in the management of these patients. in t...

When we made a detailed examination with TTE, we saw that the transvenous temporary pacing was not in the jugular vein. The suprasternal view showed the lead of the pacemaker in the arcus aorta (Fig. 3A). The localization of the pacemaker lead was seen in the right ventricle by fluoroscopy in the RAO. But, we were sure the localization of lead in the left ventricle when we was seen by fluorosco...

Background & Aims: Atopic dermatitis is a common allergic disease recognized as a threat to public health. Atopic dermatitis is often observed in people with individual or family history of allergic diseases. Due to the importance of this disease and its early diagnosis, and the very limited number of studies on this topic, the current study was performed on the prevalence of atopic dermatitis ...

BACKGROUND Naringenin (NRG) is a common dietary polyphenolic constituent of fruits. NRG has diverse pharmacological activities, and is used in traditional medicine to treat various diseases including gastrointestinal (GI) disorders. Interstitial cells of Cajal (ICCs) are pacemaker cells of the GI tract. In this study, the authors investigated the effects of NRG on ICCs and on GI motility in vit...

In a rate-stable pacemaker, pacemaker rate reflects battery voltage level and should remain constant or be slightly depleted with time in a linear fashion until failure occurs. Linear regression techniques are therefore particularly suited to the analysis of pacemaker rate data. Data on model 8114/8114A Starr-Edwards pacemakers followed at the University of Oregon Health Sciences Center were st...

Cellular mechanisms underlying the primary circadian pacemaker in mammals were investigated by isolating rat suprachiasmatic nuclei in brain slices and maintaining them in vitro for up to 3 days. The circadian rhythm of neuronal firing rate was used to assess the phase of the pacemaker. This rhythm was rapidly reset by bath application of cAMP analogs. Moreover, the pacemaker demonstrated circa...

atopic dermatitis (ad) is one of the most common infantile diseases. immunological dysfunctions in ad patients may predispose them to infections. the aim of this study was to evaluate the relationship between infantile ad and urinary tract infection (uti). in this cross sectional study, we enrolled 57 patients with ad aged 1 to 24 months that referred to dermatology clinic, and 57 healthy contr...

abstract background: atopic dermatitis is a common skin disease associated with chronic inflammation in the skin and itches and most patients have a positive family history of dermatitis. the major treatment of dermatitis, based on allopathic medicine, includes symptomatic treatment by oral antihistamines and topical or oral corticosteroids, which, in long-term, will cause various side effects....
