RESUMEN
This paper reports a case of Tinea imbricata in a young Orang Asli boy which was noted during his admission for severe symptomatic anemia. Upon discharge, he was started on syrup Griseofulvin 10mg/kg daily and Whitfield cream for 4 weeks. The Department of Orang Asli Development (JAKOA) and the local Health Clinic were contacted before discharge to facilitate patient's follow-up and monitoring. Outbreaks of Tinea imbricata among the Orang Asli have been known to happen from time to time. Although this dermatophyte infection is rare in the urban population, transmission among travelers has been reported. This case report highlights its unique presentation and treatment approach.

Topical corticosteroids are common medications prescribed for skin problems encountered in the primary care or dermatology clinic settings. As skin conditions comprise of around 20% of cases seen in primary care, this article written to guide readers, especially non-dermatologists on the appropriate potency of topical corticosteroids to be chosen for skin problems of patients and to list the side effects both local and systemic.

Most of the dermatophyte species have the ability to perforate hair structure and consume its contents of keratin through secretion of keratinase enzyme. Two clinical isolated species of dermatophytes were diagnosed as Trichophyton mentagrophytes var. granulosum and Trichophyton verrucosum. To determine the perforation ability, the isolated fungi were incubated with the hair of four different animals (rabbit, rat, cow and cat) and human hairs with three different colours (black, albino and bleached yellow) for different periods. Variable perforating ability of T. mentagrophytes was shown in rat hair and all types of human hair after 15 days, while other mammalian hairs exhibited resistance to this fungal activity. On the other hand, T. verrucosum was revealed a slow perforating ability, which needed a long time (60 days) for most of tested hairs. Perforation of human black hair could be considered a diagnostic test for differentiation between T. mentagrophytes and T. verrucosum. In conclusion, the treated or untreated human hair was considered more suitable to use as a source of keratin for the growth of dermatophytes than animal hairs. The human black hair was a best type of hair to use in the perforating test for differentiation between T. mentagrophytes and T. verrucosum.

Uranium concentration in groundwater samples from three areas of Syria was determined using alpha-spectrometry and INAA. It was in the range of 0-6.13 microg/l in the phosphate areas, and lower than 1 ppb in the volcanic areas. The activity ratio of 234U/238U was investigated, and disequilibrium of uranium isotopes was found to occur (234U/238U = 0.52-2.02). The excess of 234U was calculated. This excess can be interpreted by higher mobility of 234U, which more readily forms the soluble (UO2)2+ ion in comparison with 238U, most of which remains in the insoluble 4+ state. This excess increases with increase in uranium concentration. Thorium concentration was measured using INAA, it was found to be in the rang 0-1.15 microg/l.

A combination of several exploration techniques was carried out in AL-Abter region, aiming at outlining the main characteristics of the phosphatic layers in this region. The techniques used in this research are natural 7-ray well logging, gamma and alpha-spectrometry. It is shown that uranium concentrations in the samples taken from the wells studied vary between 42.8 and 112.5 ppm with a standard deviation of 15.2 ppm. The P2O5 content varies between 20.5% and 28.31% with a standard deviation of 3.11% and the radioactive intensities vary between 150 and 275 counts per second (cps) with a standard deviation of 31 cps. The ratio of 234U/238U in the analyzed samples indicates that the study region is in radioactive equilibrium. The affinity of uranium and P2O5 to some trace elements, such as V, Sr, Cu and Ni has been verified through studying the correlation matrix of these elements.
