Maxillary Sinus Epidermoid Cyst: A Case Report.

The preoperative diagnosis of a paranasal epidermoid cysts (EC) is challenging and is frequently mistaken. We present the case of a patient who developed a swelling on the left side of the face. The clinical examination showed a fixed and poorly defined swelling in the left maxillary region, with a slightly painful bulge in the upper vestibular peri-gingival area.

Anaplastic Thyroid Carcinoma Mimicking Cervical Tuberculosis: A Case Report.

Anaplastic thyroid carcinoma is a rare and aggressive form of thyroid cancer that has a poor prognosis and a high mortality rate. It is characterized by rapid growth and invasion of nearby tissues. It typically presents as a rapidly growing goiter or nodule that is firm to the touch and firmly attached to the underlying structures.

[A rare cause of AA amyloidosis: Hereditary epidermolysis bullosa].

Introduction: Recessive dystrophic epidermolysis bullosa is a rare genetic condition characterized by fragile skin and mucous membrane, caused by mutations in the COL7A1 gene. AA amyloidosis is a rare complication of these genodermatosis.

Observations: Two patients with recessive dystrophic epidermolysis bullosa, generalized severe in the first case and generalized intermediate in the second case, developed at the age of 38 and 28, respectively, nephrotic syndrome.

Chondroitin/dermatan sulfate purified from corb (Sciaena umbra) skin and bone: In vivo assessment of anticoagulant activity.

The present work deals with the extraction and purification of chondroitin sulfate/dermatan sulfate from skin (CSG) and bone (CBG) of corb (Sciaena umbra). Electrophoresis of these polymers in barium acetate buffer on cellulose acetate revealed two fractions similar to dermatan sulfate and chondroitin sulfate. The in vivo anticoagulant activity of both chondroitin sulfate/dermatan sulfate (CS/DS) were evaluated, at 25 and 75 mg kg of body weight (b.

Polysaccharide from Pimpinella anisum seeds: Structural characterization, anti-inflammatory and laser burn wound healing in mice.

The polysaccharide preparation from Pimpinella anisum seeds (PAP) was isolated and characterized to evaluate its laser burn wound-healing and anti-inflammatory activities in mice. The structure characterization of PAP by Infra-red spectrometry (IR), Nuclear magnetic resonance (NMR), Gas chromatogram-Mass spectrometer (GC-MS) and colorimetric methods revealed an optimum yield of 8.84%, a high quantity of carbohydrate (64.

Combination of amphotericin B and caspofungin in the treatment of mucormycosis.

We report a case of invasive mucormycosis in 52 year-old woman. CT-scan and magnetic resonance imaging found a partial right sinus thrombosis associated with homolateral ethmoidal and maxillary sinusitis with submucosal inflammation. Histopathological examination of excised tissue was positive for mucormycosis.

Sulfated polysaccharide isolated from Globularia alypum L.: Structural characterization, in vivo and in vitro anticoagulant activity, and toxicological profile.

A sulfated polysaccharide from Globularia alypum L. (GASP) was extracted with a yield of 14.2%.

Combined use of Vitamins E and C improve nephrotoxicity induced by colistin in rats.

This study was performed to investigate the protective effect of combined use of Vitamins E and C on colistin-induced tubular damage in rat. Animals were treated with sterile saline, colistin methanesulfonate (CMS), CMS + Vitamin E + Vitamin C, and Vitamin E + vitamin C, respectively, for seven days. Thereafter, animals were sacrificed and the urine N-acetyl-b-D-glucosaminidase (NAG) and gamma-glutamyl transferase (GGT) levels, plasma level of creatinine (Cr), vitamin E and vitamin C, and renal tissue levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), as well as renal histology were performed.

Effect of vitamin E on reversibility of renal function following discontinuation of colistin in rats: Histological and biochemical investigations.

This study was carried out to evaluate spontaneous renal regeneration after stopping colistin methanesulfonate (CMS), which induces tubular damage, and the curative effect of Vitamin E (vit E) in rats. Animals were given the following: sterile saline (n = 6), 300,000 IU/kg/ day of CMS (n = 24), or 450,000 IU/kg/day of CMS (n = 24) for seven days. Each CMS group was subdivided into four subgroups (n = 6) and sacrificed as follows: (i) 12 h after stopping CMS, (ii) two weeks after stopping CMS, (iii) two weeks after stopping treatment with vit E, and (iv) two weeks after stopping treatment with olive oil.

Ewing's sarcoma of the cranial vault: a case report.

Ewing's sarcoma is a malignant tumor that mainly affects young patients. It represents 10% of primary malignant tumors of the bone and 3% of malignant tumors of the child. Cranial localization is extremely rare representing less than 1% of all the localizations.
