Giant primary adrenal hydatid cyst presenting with arterial hypertension: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>A primary hydatid cyst of the adrenal gland is still an exceptional localization. The adrenal gland is an uncommon site even in Morocco, where echinococcal disease is endemic.</p> <p>Case presentation</p> <p>We report the case of a 64-year-old Moroccan man who presented with the unusual symptom of arterial hypertension associated with left flank pain. Computed tomography showed a cystic mass of his left adrenal gland with daughter cysts filing the lesion (Type III). Despite his negative serology tests, the diagnosis of a hydatid cyst was confirmed on surgical examination. Our patient underwent surgical excision of his left adrenal gland with normalization of blood pressure. No recurrence has occurred after 36 months of follow-up.</p> <p>Conclusion</p> <p>There are two remarkable characteristics of this case report; the first is the unusual location of the cyst, the second is the association of an adrenal hydatid cyst with arterial hypertension, which has rarely been reported in the literature.</p

Geology and mineralogy of a sepiolite-palygorskite occurrence from SW Eskişehir (Turkey)

The present occurrence is the only deposit among those found in Eskisehir province containing both sepiolite and palygorskite in economic amounts. To describe the geology, mineralogy and genetic relationships, two representative measured sections were examined by field work and XRD, XR.F and SEM analyses. Sepiolite and palygorskite occur in a similar to 40 m thick part of Pliocene sequence where saponite is also found. These minerals appear in ascending order as: palygorskite, saponite, saponite + palygorskite, sepiolite and sepiolite + palygorskite, frequently in association with dolomite. Chemical precipitation from the alkaline lake environment under semiarid or arid conditions was the main process resulting in sepiolite, palygorskite and saponite formation. Of these, saponite and palygorskite were formed when the lake water was rich-in Al and Fe. Changes in may have controlled whether saponite or palygorskite could be formed. Palygorskite was also developed by transformation from saponite during diagenesis

Characterization of two forms of sepiolite and related Mg-rich clay minerals from Yenidoğ an (Sivrihisar, Turkey)

An Early Pliocene sedimentary succession in the Yenidogan area, Sivrihisar, Turkey, consists of sepiolite, stevensite, kerolite, dolomite and magnesite. The geology, mineralogy and geochemistry of the succession was examined by extensive field work along several trenches and a representative measured section, followed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermal, and chemical analyses

Characterization of a Mg-rich and low-charge saponite from the Neogene lacustrine basin of Eskisehir, Turkey

The saponite examined Occurs as two 0.1 in thick layers in a Pliocene sequence consisting of dolomite and dolomitic marl. To characterize this material, mineralogical and structural analyses (XRD, SEM and FTIR), thermal analyses (DTA, TG) and chemical analyses (ICP-ES) were performed. From XRD patterns of randomly-oriented powder samples, the first basal reflection appears as an asymmetric and broad peak with d(001) values varying between 16.55 and 17.32 angstrom. In oriented and air-dried samples, this reflection Occurs between 14.45 and 16.42 angstrom and is fairly symmetrical with FWHM of 2.7 degrees 20. Oriented and ethylene glycol-solvated samples produce a rational series of basal reflections, where 001 occurs at similar to 17.8 angstrom as an intense, narrow (1.1 degrees 20) and fairly symmetrical reflection. Upon solvation with glycerol, the 001 reflection shifts to similar to 18.7 angstrom

Current-voltage characteristics and aging of sepiolite oriented by magnetic field

Current-voltage characteristics and aging properties of modified sepiolite taken from Anatolia have been studied. Sepiolite mineral dispersed by ultrasonic methods and saturated with Fe2+ by ion-exchange has been oriented in an 11 kG magnetic field. DC measurement techniques have been applied to ribbon type samples oriented in a magnetic field. Whereas, application of these techniques to samples that have not been oriented in a magnetic field was possible because of very small and unstable current, samples oriented in a magnetic field have shown a linear change. The current-voltage studies done at different time periods have shown that sample resistance has risen in time approximately 100 times, and aging has begun. This has been evaluated as being the result of sepiolite interaction with water vapor in the medium, rather than the oxidization of the contacts. (C) 1999 Elsevier Science B.V. All rights reserved
