    Background: There is growing interest in physical medicine treatment options for renal colic. In this study, we aimed to determine whether or not heat-patch treatment with no drug was effective in relieving renal colic. Methods: For this purpose, patients who were diagnosed with renal colic in the emergency department were randomised to have either heat-patch or sham treatment. The Visual Analogue Scale (VAS) scores of renal colic, body temperature (Btemp), and sub-patch skin temperature (Stemp) values were measured at 0, 15, 30, 45, and 60 minutes. In addition, the salvage treatment needs of the groups were compared. Results: The average age of the study group was 30.5 ± 8.3 years and that of the sham group was 31.0 ± 8.2 years (P =.75). According to the baseline VAS score of the patients, 15, 30, 45, and 60 minutes VAS scores significantly decreased in the heat-patch group (P <.001). The Btemp values did not differ significantly between the heat-patch and sham groups. In addition, no statistically significant difference was found between the two groups in terms of Stemp values at 0 and 15 minutes (P =.39 and P =.10, respectively). However, there was a significant difference in the heat-patch group in terms of Stemp values at 30, 45, and 60 minutes compared with the sham group (P <.001). The salvage treatment rates for the heat-patch and sham groups were 11.5% and 31.4%, respectively (P =.01). Conclusion: As non-pharmaceutical treatment, the heat-patch has been shown to be a possible candidate for pain relief in patients with urolithiasis. Further research should concentrate on multicentre and large scale randomised studies. © 2020 John Wiley & Sons Ltd

    Geology, Geochemistry, and Geochronology of the Giant Pelitic Mafic-Type Karaburun Volcanogenic Massive Sulfide Deposit (Central Pontides, Turkey)
    (Society of Economic Geologists, Inc, 2025) Cavdar, B.; Günay, K.; Oyan, V.; Mutlu, H.; Dönmez, C.; Çiftçi, E.; Tessalina, S.
    Anatolia hosts different types of volcanogenic massive sulfide (VMS) deposits in the Eastern Pontides, Bitlis-Zagros suture zone, and Central Pontides. The recently discovered giant Karaburun deposit (~125 million tonnes [Mt] grading 1.16 wt % Cu, 0.25 wt % Zn, and 0.05 wt % Co) of the Central Pontides is the largest VMS deposit in Turkey. The mineralization is hosted within the greenschist metamorphosed rocks of the Çangaldağ Metamorphic Complex. Mineralization is associated with metamorphosed volcaniclastic, clastic detrital sedimentary, and deep marine sedimentary rocks, as well as crosscutting submarine mafic dikes and/or sills. The deposit mainly occurs as a stratiform Cu-Zn ± Co sheet-like and tabular body that contains disseminated, banded, pyritic clastic, semimassive, and massive sulfide textures. The primary ore minerals are pyrite, chalcopyrite, sphalerite, magnetite, and trace galena. Supergene covellite, bornite, chalcocite, and digenite are observed. Surface weathering and oxidation resulted in hematite, goethite, lepidocrocite, malachite, and water-soluble copper minerals. Mineralization-stage pyrites yield an age of 163.6 ± 7.1 Ma (Re-Os; Late Jurassic; lowermost Oxfordian), which is consistent with the ages of different components in the same rifting system. The δ34S values of pyrites range from 3.07 to 5.10%, suggesting a mixed origin between basalts and thermochemically reduced seawater sulfate. Late Cretaceous metamorphism caused brittle and ductile deformation within the sulfide phases, promoting the remobilization of metal-bearing minerals. Subsequent deformation phases likely led to the dismemberment and juxtaposition of mineralized levels. Together, the data indicate that Karaburun is a pelitic-mafic replacement-type VMS deposit that formed in a back-arc basin environment of the Jurassic ensimatic arc-back arc-rift system. © 2025 Society of Economic Geologists, Inc.
