Damage Control Surgery
Objective: The basis of damage control surgery rests on quick control of life-threatening bleeding, injuries, and septic sources in the appropriate patients before restoring their physiological reserves as a first step followed by ensuring of the physiological reserves and control of acidosis, coagulopathy, and hypothermia prior to complementary surgery
Investigation of structural, spectral, electronic, and biological properties of 1,3-disubstituted benzimidazole derivatives
This article reports studies on benzimidazole based heterocyclic compounds (S3 -S5). X-ray diffraction technique was applied to study the structure of (C23H19N4O2)(+).Br-.H2O, namely 1-[(2-cyanophenyl) methyl]-3-[2-(4-nitrophenyl)ethyl]-1H-benzimidazol-3-ium bromide monohydrate (S3). The molecules are linked by C-H/Br hydrogen bonds in the crystal and there are pi-pi stacking interactions between the centroids of the benzene ring in the benzimidazole nucleus. The theoretical, and chemical data of S3-S5 were compared with experimental calculations via NMR, IR, and UV-Vis spectra of the molecules. Afterwards, the biological activities of the molecules were compared against colon cancer antigen pro-teins, ID 2HQ6, and a breast cancer protein, which is a crystal structure of a dimeric caspase-9, ID 2AR9. Experimental and theoretical studies have shown that the biological activity of the molecule S5 is higher than that of other molecules. (C) 2020 Elsevier B.V. All rights reserved
Report of Two Cases with Simultaneously Detected Tubular Carcinoma and Phyllodes Tumor of the Breast
Tubular carcinoma (TC) is a subtype of invasive breast carcinoma with better prognosis, and phyllodes tumors (PT) are rare fibroepithelial lesions. Accurate preoperative pathological diagnosis allows for correct surgical planning and avoidance of reoperation for these breast neoplasms. A database was created by analyzing the archives of Department of General Surgery of the Istanbul Faculty of Medicine between September 2006 and November 2017, and a total of 105 PTs and 55 TCs were collected. Two cases with concurrence of TC and PT were identified and examined in detail. The first patient was a 33-year-old woman with a 20x12 mm(2) TC and a 65x32 mm(2) malignant PT in the left breast. The second patient was a 28-year-old woman with two masses in the right breast. The first mass was 38x16 mm(2) on the upper outer quadrant, and the second mass was 10x8 mm(2) in size in the lower inner quadrant, accompanied by a 16x10 mm(2) TC and a 33x26 mm(2) borderline PT. Both cases were treated by mastectomies due to patient's decisions or insufficient margin control. This study extrapolated that if two tumors are detected simultaneously, margin control can become more difficult, and breast-conserving surgery should be thoroughly reviewed
Pinch-Off Syndrome, a Rare Complication of Totally Implantable Venous Access Device Implantation: A Case Series and Literature Review
Background: Pinch-off syndrome (POS) is a rare complication after totally implantable venous access device (TIVAD) implantation. In cancer patients, it is important to prevent this rare complication and to recognize it early if it does occur. We present a case series of POS after TIVAD implantation and the results of a literature search about this complication. Methods: From July 2006 to December 2015, 924 permanent implantable central venous catheter implantation procedures were performed. The most common indication was vascular access for chemotherapy. Results: POS occurred in 5 patients in our clinic. Two patients experienced POS within 2 weeks, and the other 3 patients were admitted to department of surgery, Istanbul Faculty of Medicine at 6 to 14 months following implantation. The catheters were found to be occluded during medication administration, and all patients complained of serious pain. The transected fragments of the catheters had migrated to the heart. They were successfully removed under angiography with a single-loop snare. Conclusion: POS is a serious complication after TIVAD implantation. It is important to be aware of this possibility and to make an early diagnosis in order to prevent complications such as drug extravasation and occlusion events
The Rate of Idiopathic Spontaneous Pneumoperitoneum is 2.36%
Objective: Pneumoperitoneum often occurs following a visceral perforation, often seen with peritonitis, and requires urgent surgical intervention. Non-surgical spontaneous pneumoperitoneum (not associated with organ perforation) is a rare condition caused by intrathoracic, intraabdominal, gynecologic, iatrogenic, and other causes, and may be treated conservatively. Spontaneous idiopathic pneumoperitoneum is not caused by visceral perforation, the cause may be extra-abdominal origin and sometimes cannot be determined
