Abstract Geochemical data and their various approaches are useful to evaluate the climatic control on depositional environments. This study aims paleoweathering plaeoclimate condition that have controls environments of Miocene Pliocene siliciclastic sequence at Al-Rehaili area, north Jeddah. To achieve this aim, selected sandstone samples were geochemically (major trace elements analysis) petro...

INTRODUCTION Scleromyxedema is a rare, chronic and progressive disorder of unknown origin characterized by a generalized papular eruption and sclerodermoid induration, with histopathologic features of mucin deposition and fibroblast proliferation. The disease is usually associated with a monoclonal gammopathy. However, only a few cases associated with neoplasms have been reported. We report a c...

Electron microscopical studies of primary syphilitic lesions showed intensive changes in the capillaries in the form of endothelial proliferation and extensive infilitration of different cells in the surrounding connective tissue. The degenerative changes in axon terminals could explain the painless course of primary induration.

Yolk sac tumor is a non-seminomatous testicular germ cell rarely found in adults. It an extra-embryonic differentiated tumor. reproduces structures evocative of the yolk humans. We report clinical case 37-year-old patient, with no previous history, who followed up for left testicle revealed by increase size and induration testicle. The orchiectomy, performed through inguinal approach, allowed u...

Scleromyxedema is a rare and distinctive variant of cutaneous mucinoses of unknown etiology. It is presenting with generalized papular eruption and sclerodermoid induration. Numerous treatment modalities have been reported to produce partial or permanent responses. This study reports on a case of scleromyxedema without paraproteinemia in a subject who experienced a partial response to thalidomi...

Guinea pigs sensitized by repeated skin testing with potent, merthiolated coccidioidin, equal to Smith standard, exhibited erythema, edema, and an induration-like reaction to intradermal injection of the preparation. No statistically significant migration inhibition of peritoneal exudate macrophages from these animals was observed.

Lowell’ gave the incidence of allergy to streptomycin as 10 per cent. This high incidence is due to administration of the drug for long periods in tuberculosis. Most of the allergic reactions were not serious. There was no way of knowing whether a patient allergic to streptomycin could react again on re-administration. It might be assumed that he would.
