Background/aims: Liver transplantation is a life-saving approach in some cases of mushroom poisoning, which is one of the important causes of acute liver failure. However, debate continues regarding the timing of liver transplantation. The aim of this study is to retrospectively evaluate the results of patients who underwent liver transplantation due to mushroom poisoning.

Background: Head trauma is a leading cause of death and disability. While standard treatment protocols exist for severe head trauma, no clear follow-up standards are available for mild head trauma with positive imaging findings in infants and newborns. Although routine follow-up brain computed tomography (CT) imaging is not recommended for children with moderate and mild head trauma, the necessity for follow-up imaging in infants and newborns remains uncertain.

The low temperature synthesis of MCM-48 was performed and its adsorptive properties were investigated for the first time in literature by studying Basic Red 29 (BR29) dye adsorption from model solutions. The modification of the surface properties and pore structure of silica-based material MCM-48 induced by BR29 adsorption were characterized using XRD, nitrogen physisorption, and SEM methods before and after dye adsorption. The effects of contact time, solution pH, dye concentration, and temperature on the adsorption capacity of MCM-48 were investigated.

Background: Acute appendicitis is the most common cause of non-obstetric acute abdomen in pregnant women. We examined the patients who were admitted to our emergency department with abdominal pain and diagnosed with acute appendicitis in the light of the literature.

Methods: Seventeen pregnant patients with acute appendicitis who were admitted to the emergency department of Sanliurfa Training and Research Hospital between the years of 2016-2019 were retrospectively analyzed using an electronic recording system.

Background: The aim of this study is to retrospectively and multi-centerly examine the clinicopathological features of patients who were operated with the diagnosis of mesenteric cyst, which is a rare cause of intra-abdominal mass in the last 9 years, in the light of the literature.

Methods: The patients were operated due to mesenteric cysts in the general surgery clinics of two Training and Research Hospital between 2010 and 2019; age, gender, preoperative clinical findings, computed tomography (CT) findings, localization of the mass, surgical procedure, morbidity, histopathological results, and follow-up period status were analyzed and reported electronically.

Results: The patients generally applied with the complaints of abdominal pain, palpable abdominal mass, and abdominal distention.

Background: Appendiceal mucocele is a rarely seen disease which occurs when the appendix lumen is filled and obstructed by mucous. In our study, we aimed to reveal the surgical approach of our clinic, features of tumors, and clinical presentations in line with literature in cases of appendix mucocele.

Methods: Fourteen appendix mucocele patients who were admitted in our hospital between 2012 and 2019 were examined retrospectively in the electronic recording medium.

Hydatid cyst is a helminthic infection caused by that we encounter in various organs, especially in the liver and the lungs. Hydatid cyst of the breast is seen very rarely even in regions where the disease is endemic. In this article, we aimed to present a female patient who presented with complaints of a mass in her right breast, was diagnosed as having hydatid cyst as a result of physical examination and radiological imaging methods, and was treated.

Article Synopsis
  • The study investigates the effectiveness of electrocoagulation (EC) in treating vinegar industry wastewater (VIW) using aluminum and iron electrodes, focusing on various factors that influence treatment efficiency.
  • Results show that aluminum electrodes achieve a 90.91% chemical oxygen demand (COD) removal at pH 4 and specific conditions, while iron electrodes achieve 93.60% COD removal at pH 9.
  • Additionally, toxicity tests indicate that the EC process not only reduces COD levels but also diminishes the toxicity of the wastewater, making it a viable treatment option for high organic pollutant levels in VIW.

Objective: Gastrointestinal stromal tumors are believed to play a role in immunosuppression with their local effect. In some cancers with associated inflammation, an increased pretreatment neutrophil lymphocyte ratio is considered as an indicator of poor prognosis. The aim of our study was to assess the relationship of increased blood neutrophil lymphocyte ratio with disease prognosis in patients with gastrointestinal stromal tumors.

The aim of this study is the treatment of Basic Red 29 (BR29) dye solution using hybrid iron-aluminum electrodes by electrocoagulation and electro-Fenton methods. The effect of current density, initial pH, supporting electrolyte, H₂O₂, and initial dye concentration on dye removal efficiency was investigated, and the best experimental conditions were obtained. Time-coarse variation of UV-Vis spectra and toxicity and chemical oxygen demand (COD) removal were also examined at the best experimental conditions.

Electrochemical oxidation of Basic Red 29 (BR29) was studied in a bipolar trickle tower (BTT) reactor by using Raschig ring shaped boron-doped diamond (BDD) electrodes, which were originally employed by the present researchers, in a recirculated batch mode. The model solution was prepared with BR29 using distilled water. The effects of initial dye concentration, Na(2)SO(4) concentration as supporting electrolyte, current density, flow rate and initial pH on the removal efficiency were investigated, and practically, complete BR29 removal (over 99%) was obtained in all the studies.

In this study, electrochemical oxidation of phenol was carried out in a parallel plate reactor using ruthenium mixed metal oxide electrode. The effects of initial pH, temperature, supporting electrolyte concentration, current density, flow rate and initial phenol concentration on the removal efficiency were investigated. Model wastewater prepared with distilled water and phenol, was recirculated to the electrochemical reactor by a peristaltic pump.
