Any possible association between Behcet's disease and retinitis pigmentosa

Behcet's disease is a rare multisystem disease; it has many ocular features, and it is not known to be associated with dystrophic conditions such as retinitis pigmentosa [RP]. This is a case report of a Sudanese patient with Behcet's disease with ocular features and RP. A 28-year-old female with nyctalopia, skin hyper-pigmentation, and oral and genital ulcers was diagnosed as RP with Behcet's disease. She received a high dose of steroids and Azathioprine. She developed bilateral cataract and glaucoma. Pathergy test is negative. The patient is fulfilling the diagnostic criteria of both RP and Behcet's diseases. Behcet's disease is a rare condition; it is not common among Sudanese patients, and it has not been known to co-exist with RP

Hydrology of qarun lake, el Fayoum depression, Egypt

Qarun Lake constitutes the most important and striking feature of El Fayoum depression. It constitutes the remnants of the ancient fresh Moris Lake. It is now forming a promising area for new development projects such as salt production, fisheries and tourism. Unfortunately, the continuous rise of the Lake water level and salinity content not only threaten the old agriculture activities but also the new developed ones. A water budget model was applied through the year 2005 to estimate the quantity of the excess water that causes these problems. Accordingly, the inflow water is estimated as 586.42 million m[3] and outflow water amounts to 436.22 million m[3], so the storage content equals 150.33 million m[3]. This amount of water is being stored in the lake every year and is responsible for the continuous rising of the lake level. Reviewing the actual water quantity stored in the lake through the same interval reveals that an amount of water equals 175.88 million m[3]. This means that the quantity of water actually stored in the lake exceeds the quantity of water that enters the lake through precipitation, groundwater seepage and drainage water [inflow water] by 25.55 million m[3]. This addational quantity recharges the lake besides the previously mentioned sources. The source of this water may attribute to the upward leakage from the deep aquifers and/or seepage from Wadi El Rayan lakes along deep fissures and fractures. The higher bottom salinity of the lake's water than the surface salinity enhances this result. The salinity difference ranges from 0.01 g/l to 2 g/l with an average value amounts to 0.77 g/l. In a trial to predict the behavior of the lake surface in the next ten years, the lake level is simulated using the MODFLOW package [version 5]. The simulation reveals that, the lake level is expected to rise from -43.09 m to -41 .5m. This means that the lake receives 223.5 million m[3] of excess water, which may damage additional areas around the lake

Antimicrobial activity of oil bitter orange

The oil of bitter orange was tested for its antimicrobial activity against clinical isolates of different bacterial and fungal species. The oil was shown to possess antimicrobial activities against multiply resistant clinical isolates of Staphylococcus aureus [46 isolates], Escherichia coli [37 isolates] and Pseudomonas aeruginosa [36 isolates]. Among the tested bacteria, the Gram-positive isolates were more sensitive to the oil than the Gram-negative ones. The oil was shown to possess fungistatic and fungicidal properties towards clinical isolates of C and ida albicans as well as four clinical isolates of dermatophytes [two isolates of Epidermophyton floccosum and two isolates of Trichophyton rubrum]. The in vitro antifungal activity of the oil was found to be comparatively higher than its antibacterial activity. Preliminary clinical trials on the value of the oil in the treatment of dermatomycosis were promising

study of the sealing ability of thermafil root canal filling material

The aim of this study was to evaluate the sealing ability of Thermafil root canal filling material as correlated with the shape of the prepared root canal walls, when instrumented with three different enlarging instruments. Fifty human central incisors were used in this study and were divided into three groups. Groups A and B, having 20 teeth in each, were prepared with square cross section K-type files and triangular cross section Flex-R files, respectively. These two groups were subdivided into two equal halves according to the mode of action used in mechanical preparation [filing or reaming action]. Group C consisted of 10 teeth prepared with triangular cross section K-type reamers using reaming action. Root canals were obturated using a standard size [50] of Thermafil with sealer. The extent of dye penetration was measured under stereomicroscope after clearing of teeth. When the results were subjected to an analysis of variance at P = 0.05, no significant difference in dye penetration existed between the three tested groups when compared as a whole. However, a significant difference existed between the subgroups prepared with different modes of action with better restriction of dye penetration in canals prepared using reaming action. Manufacturer discrepancies in Thermafil and sealer extrusion seemed to be main disadvantages
