Pneumatosis intestinalis (PI) and portomesenteric venous gas (PVG) refers to the presence of air within the intestinal wall and portomesenteric vessels. Most of the time, it is associated with mesenteric ischemia that requires immediate surgical intervention as it has high mortality rate. It may also be seen secondary to various conditions, including infections, surgeries, and some chemotherapeutic drugs. A 61-year old-male was admitted to our emergency department complaining of abdominal pain after chemotherapy. Radiological evaluation of the patient demonstrated massive PVG and PI. Patient underwent urgent surgery due to the possi . . .bility of intestinal ischemia and infarction, but no necrosis was identified Chemotherapeutic drug-induced PI and PVG was the final diagnosis. Although PI and PVG are signs of mesenteric ischemia and intestinal necrosis most the of time, chemotherapeutic drugs may also cause PI and PVG rarely. Recent history of chemotheraphy and absence of any mesenteric vascular occlusion may be the diagnostic clue. Copyright (C) 2017 The Emergency Medicine Association of Turkey.

Time-dependent Coulomb stress changes induced by the 2002-2003 Etna magmatic intrusions and implications on following seismic activities

Pulvirenti, Fabio | Aloisi, Marco | Jin, Shuanggen


In this paper, the relationship between the dike-forming magmatic intrusions and the faulting process at Mount Etna is investigated in terms of Coulomb stress changes. As case study, a complete time-dependent 3-D finite element model for the 2002-2003 eruption at Mount Etna is presented. In the model, which takes into account the topography, medium heterogeneities and principal fault systems in a viscoelastic/plastic rheology, we sequentially activated three dike-forming processes and looked at the induced temporal evolution of the Coulomb stress changes, during the co-intrusive and post-intrusive periods, on Pernicana and Santa Ven . . .erina faults. We investigated where and when fault slips were encouraged or not, and consequently how earthquakes may have been triggered. Results show positive Coulomb stress changes for the Pernicana Fault in accordance to the time, location and depth of the 27th October 2002 Pernicana earthquake (M-d = 3.5). The amount of Coulomb stress changes in the area of Santa Venerina Fault, as induced by dike-forming intrusions only, is instead almost negligible and, probably, not sufficient to trigger the 29th October Santa Venerina earthquake (M-d = 4.4), occurred two days after the start of the eruption. The necessary Coulomb stress change value to trigger this earthquake is instead reached if we consider it as induced by the 27th October Pernicana biggest earthquake, combined with the dike-induced stresses.

Ophiolitic chromitites from the Kizilyuksek area of the Pozanti-Karsanti ophiolite (Adana, southern Turkey): Implication for crystallization from a fractionated boninitic melt

Article | 2017 | ORE GEOLOGY REVIEWS90 , pp.166 - 183

Ophiolitic rocks are widely distributed in Turkey. One type, the Pozanti-Karsanti ophiolite from southern Turkey, contains a large number of chromitite deposits located mostly in the mantle peridotites and close to the Moho transition zone dunite and cumulate dunites. Cr-spinet grains from the chromitites are represented by high Cr# [100 x Cr / (Cr + Al) = 68-81], and their Mg# [100 x Mg / (Mg + Fe2+)] range from 54 to 71. Gallium and Co contents vary between 18 and 32 ppm and 185-266 ppm, respectively, and they show negative correlation with Cr#. A detailed optical investigation reveals that the Cr-spinel grains contain silicate, p . . .latinum-group mineral (PGM) and base metal sulfide (BMS) inclusions. Single phase inclusions of amphibole are the only hydrous silicate phases in the investigated chromitites, and they contain low TiO2 Daha fazlası Daha az

Present-day kinematics in the Eastern Mediterranean and Caucasus from dense GPS observations

Ahadov, Bahruz | Jin, Shuanggen


The Eastern Mediterranean and Caucasus are located among the Eurasian, African and Arabian plates, and tectonic activities are very complex. In this paper, the kinematics and strain distribution in these regions are determined and investigated from dense GPS observations with over 1000 stations and longer observations. The elastic block model is used to constrain present-day plate motions and crustal deformation. The relative Euler vectors between the Nubian, Arabian, Caucasus, Anatolian and Central Iranian plates are estimated. The Arabian-Eurasia, Anatolian-Eurasia, Nubian-Eurasia, Caucasus-Eurasia and Central Iranian Euler vector . . .s are 0.584 +/- 0.1 Myr(-1), 0.825 +/- 0.064 Myr(-1), 0.35 +/- 0.175 Myr(-1), 0.85 +/- 0.086 Myr(-1) and 0.126 +/- 0.016 Myr-1. The strain rate in the East Mediterranean and Caucasus has been estimated from the GPS velocity field. The results show that the thrust dominated areas, the eastern Mediterranean-Middle East-Caucasus and Zagros have negative dilatation and the western Anatolia region has positive 2D dilatation rate with significant rotation. The west Anatolian shows the extension in NW-SE with about 150-199 nstrain/yr in the W-E direction. The Central Anatolia shows compression rate below 50 nstrain/yr and extensional strain rate adjacent to East Anatolian Fault and Dead Sea Fault is about 0-100 nstrain/yr. The contraction strain rate is higher in Zagros and Caucasus between 100150 nstrain/yr and contraction orientation is along the NE-SW direction in Caucasus. The north part of Iran shows less contraction rate below 50 nstrain/yr but North-East Zagros Mountains, Tabriz fault and Chalderan fault show extensional rate between 50-110 nstrain/yr and principal axes rotation in the NS direction. The maximum contraction observed in the Kopek Dag is about 100-194 nstrain/yr and orientated in the NE-SW direction. East Zagros Mountain and Makran subduction zone have a large clockwise rotation with 70-85 nradian and principal axes remains mostly along the N-S direction. The observed extension is along N-S by about 0-100 nstrain/yr with counter clockwise rotation in Dead Sea Fault. The Sinai block shows shortening rate in the range of 0-100 nstrain/yr.

Acute cyanide poisoning due to apricot kernel ingestion

Tatli, Mehmet | Eyupoglu, Gokhan | Hocagil, Hilal

Article | 2017 | JOURNAL OF ACUTE DISEASE6 ( 2 ) , pp.87 - 88

Cyanide is a toxin and one of the most rapidly acting fatal poisons that human being is aware. If it is not treated promptly, encountering to cyanide poison will lead to die in minutes. Cyanide avoids cellular oxygen usage by inactivating mitochondrial cytochrome oxidase thus inhibits cellular respiration. In this case, we represent a case report describing uncommon cyanide intoxication owing to consumption of a few portion of apricot kernels and its rapid treatment with dicobalt edetate after suspection of cyanide poisoning.
