![]() ![]() It is argued that the prevailing 'crisis' in seismic research corresponds to the Pre-Maxent Age of the current situation. The traditional methods and the 'frequentist' approach used in determining the earthquake probabilities cannot end the complaints that the earthquakes are unpredictable. Secondly, points out the ongoing debate on the predictability of earthquake recurrences and lists the main claims of both sides. This paper first evaluates the earthquake prediction method (1999 ) used by US Geological Survey as the lead example and reviews also the recent models.

The lesions were not associated with itching or burning sensation. A 40-year-old male patient presented to the Department of Dermatology with a 2-3 month history of persistent pigmented patches on both upper arms. The pathogenesis has been attributed to abnormal and delayed keratinization. ![]() ‘Dirty’ brown grey cutaneous patches and plaques that can be rid off by forceful swabbing with alcohol pads characterize it. © 2011 Wiley Periodicals, Inc.įull Text Available Terra firma-forme dermatosis is a cutaneous discoloration. This series exemplifies the importance of recognizing Terra firma-forme dermatosis so as to provide rapid relief for patients and avoid unnecessary tests and treatments. Terra firma-forme dermatosis is relatively common and most often occurs in children on the neck or posterior malleolus. Before presenting to the dermatology clinic, three patients had undergone endocrine evaluations, and four had been prescribed topical corticosteroids. The most common lesion locations were the neck, ankles, and face. The median duration of lesions was 4 months. ![]() Only two patients were older than 17 years. Thirty-one patients with Terra firma-forme dermatosis were identified, including 10 who presented with Terra firma-forme dermatosis as their primary concern. A retrospective review was conducted to identify cases of Terra firma-forme dermatosis in a single-provider practice consisting of 55% pediatric and 45% adult patients. In particular, little is known about the incidence, peak age groups, and most common locations of Terra firma-forme dermatosis. There are few publications about this condition, including no case series of more than six patients. Although Terra firma-forme dermatosis was first described more than 20 years ago and is thought to be not uncommon in clinical practice, it has never been systematically studied. A diagnosis can be reached by removing lesions with gentle alcohol swabbing. Terra firma-forme dermatosis is an idiopathic condition characterized by acquired, dirtlike plaques despite normal hygiene. ![]() Terra firma-forme dermatosis: a retrospective review of 31 patients. The role of urea containing emollients in the development of this disorder remains to be determined. From a histological perspective, we highlight its resemblance to dermatosis neglecta and speculate on the role of ′neglect′ in a patient with seemingly adequate hygiene. From a clinical point of view, we lay emphasis on its unique expression and diagnosis/treatment. In this report, we describe two patients with terra firma-forme dermatosis in the setting of xerosis cutis and atopic dermatitis. Although affected patients present with typical lesions, the disorder is not well-known by dermatologists. Directory of Open Access Journals (Sweden)įull Text Available Terra firma-forme dermatosis is characterized by ′dirty′ brown-grey cutaneous patches and plaques that can simply be eradicated by forceful swabbing with alcohol pads. ![]()
