Facial and cervical area sinus tracts can be odontogenic or non-odontogenic, and so clinicians should be aware that lesions with a dental origin can be confused with dermatological lesions. We describe three cases of cutaneous lesions of dental origin that were initially misdiagnosed as being dermatological in origin. Multiple unsuccessful treatments were attempted but the lesions failed to hea...

In this paper we applied a new analytic approximate technique Optimal Homotopy Asymptotic Method (OHAM) for treatment of coupled differential-difference equations (DDEs). To see the efficiency and reliability of the method, we consider Relativistic Toda coupled nonlinear differential-difference equation. It provides us a convenient way to control the convergence of approximate solutions when it...

Endochondral pseudocyst of the auricle is an uncommon, though distinctive clinicopathological entity occurring mainly in young men. An additional case is reported and the differential diagnosis and pathogenesis discussed. It is suggested that lymphatic dilatation of normally present tissue planes could be the most likely causative mechanism. Minor trauma to susceptible ears also seems to be a r...

Dermatologists and occupational physicians are those who have to deal with airborne allergens and irritants most often, and the awareness of these substances has grown over the years. In this report, skin symptoms of airborne dermatosis, the nature of airborne contactans, and the localization of lesions are presented, along with the differential diagnoses. Recognizing the characteristic nature ...

A review of the etiology, clinical, radiological and laboratory presentation, differential diagnosis and management of spinal stenosis is presented.

BACKGROUND To overcome the drawback of individual item-by-item box plots of disclosure for patient views on healthcare service quality, we propose to inspect interrelationships among items that measure a common entity. A visual diagram on the Internet is developed to provide thorough information for hospitals. METHODS We used the Rasch rating scale model to analyze the 2003 English inpatient ...

Indication/purpose: To review contrast-enhanced ultrasound features of the most common pancreatic tumours. Methods: Contrast-enhanced ultrasound (CEUS) can provide distinctive features of pancreatic tumours that are reported in the present paper, providing radiologic-pathological correlations and clarifying the main differential diagnosis. Conclusion: Contrast-enhanced ultrasound plays a well-e...
