The NE-SW trending Mubarak shear belt in the Central Eastern Desert (CED) of Egypt records the structural features of a transpression regime. Structural interpretation of satellite data and field observations indicates the presence of two episodes of deformation. The less dominant D1 deformation is related to sinistral movement along NW-SE trending Wadi Abu Dabbab shear zone and formation of F1 tight to isoclinal non-cylindrical folds and thrust fan as a consequence of transpression. The thrust fan includes ESE- to SE-dipping thrusts in the ophiolitic mélange and S- to SSW-dipping thrusts in the northern part of the metagabbro-diorite complex. The transpression-related sinistral shear regime is superimposed by the dominant D2 dextral transpression along NE-SW trending Wadi El-Umra shear zone. This dextral shearing is characterized by development of NNE- to NE-trending S2 cleavage, strike-slip duplex, NNE- and NE-trending F2 folds, and NNW-directed thrusts. These two events represent a single progressive phase associated with sinistral transpressional deformation, which is related to a younger E-W shortening event. E-W directed shortening is due to oblique convergence between East and West Gondwana along the Mozambique belt. Transpressional structures in the NE-SW trending Mubarak-Barramiya shear belt indicate highly oblique convergence leading to wrench-dominated dextral transpression and development of a major flower structure between Wadi Mubarak and Hafafit dome occupying the whole width of the CED. © 2010 International Association for Gondwana Research.

Natural latex from the rubber tree Hevea brasiliensis is an allergen in persons with significant cumulative latex exposure, such as those in the health care and rubber industries as well as those undergoing repeated surgeries; especially if they undergo surgeries early in life .Symptoms of latex allergy may progress rapidly and unpredictably to anaphylaxis. Since 1985, due to wide spread of human immunodeficiency virus leading to the increase in the use of latex gloves and also latex condoms, true increase in the number of persons with latex sensitivity has been noticed. Once an individual has become sensitized, he/she may experience allergic symptoms when exposed to any product containing latex. In the current case report; a known woman of latex allergy had exposed to elective cesarean section. She had developed severe anaphylactic shock and cardiac arrest during the operation. Anti-shock measures and D.C. shock therapy were done; and her heart started to beat again. After the operation had finished she was shifted to the intensive care unit to continue the management and monitoring, she stayed unconscious for five days till death. The main cause of death of this woman is the lack of knowledge about the safe measures which had to be followed in management of such cases.
