Hemangiomas are the most common benign neoplasms affecting the liver. They occur at all ages. Most cases are asymptomatic and do not require any treatment. Rarely, hemangiomas can be pedunculated. İf they undergo torsion and infarction, they become symptomatic. Herein; we report the case of a 31 year old male presenting with features of acute appendicitis: continuous right iliac fossa pain, rebound, guarding tenderness at McBurney' s point, nausea, anorexia, shifted white blood cell count and a Mantrels score of 6. At laparotomy a normal appendix was observed and a torsioned pedinculated liver hemangioma turned out to be the cause.

Background and objective The effective use of endoscopic retrograde cholangiopancreatography (ERCP) has been on the rise in diagnosing and treating benign and malignant pathologies of the common bile duct and pancreas. ERCP, a complex procedure requiring high knowledge, skills, and practice, differs from other endoscopic applications as it involves the use of different techniques and equipment and the occurrence of more complications. The most commonly observed complications of ERCP are pancreatitis, bleeding, perforation, and infections. In this study, we aimed to assess the incidence of post-ERCP complications to identify the associated risk factors and indications. Methodology In this study, 181 ERCP procedures performed on 122 consecutive patients in the endoscopy unit of Istanbul Training Hospital were prospectively evaluated by using an observational method to determine the frequency of and risk factors for post-ERCP complications. The patients were followed up in the course of the ERCP procedure and for 30 days after the procedure; the complications and clinical developments were recorded. Results The mean age of the cohort was 59.7 ± 17.7 (19-97) years; 40.9% were female and 59.1% were male. The cannulation success was achieved in 77.3% of the ERCP procedure performed. Among the ERCP procedures applied, 89% were performed for therapeutic purposes, and choledocholithiasis (60.2%) was the most common indication for ERCP. Major complications were detected in 25.4% of the patients after ERCP. The most common major complication was cholangitis (9.9%), followed by pancreatitis (7.2%), cholecystitis (5.5%), bleeding (3.9%), and perforation (1.1%). It was observed that sphincterotomy was associated with an increase in all complications. The incidence of cholangitis decreased in the presence of dilated bile ducts unrelated to obstruction. The increased incidence of pancreatitis was associated with the female gender, the use of sphincterotomy and basket, inexperienced endoscopists, and inpatient admissions. The incidence of cholecystitis, on the other hand, was found to be linked with sphincterotomy and inexperienced endoscopists. Conclusions ERCP is a complex endoscopic procedure that requires high technical knowledge and skill and can cause serious complications. For endoscopists to perform clinically effective and accurate ERCP, it is important that they correctly determine the indications for the procedure, know its potential complications, and refrain from practices that will create complications and are unnecessary as much as possible.

Up to now, there have been only a few reported cases of Mucosa-associated lymphoid tissue (MALT) lymphomas arising in the rectum. Its clinical presentation is indistinguishable from that of rectal carcinoma but the treatment is apparently different. Symptoms of primary lymphomas involving the rectum include; anorexia, weight loss, change in bowel habits, obstruction, and bleeding. These symptoms are not disease specific and can be seen in many other gastrointestinal disorders. Patients with polypoid masses may present with obstruction symptoms. In this rare case, a female patient admitted to the emergency service with prolapsus of a rectal mass.The optimal treatment of rectal MALT lymphoma is not well defined yet, given the rarity of the disease. Surgical resection of the localized lesion and following adjuvant chemotherapy has proved to be an effective treatment option. However, a close and long-lasting follow-up is important.

Amaç İlgili çalışmalarda, iyileşen ve plazmaları şiddetli akut solunum yolu sendromu-koronavirüs-2’ye (SARS-CoV-2) karşı antikorlar içeren koronavirüs hastalığı-2019 (COVID-19) hastalarından toplanan konvelesan plazma (KP) uygulanmasının güvenli olduğunu ve COVID-19 hastalarının tedavisinde etkili olabileceğini öne sürülmekte. Bu çalışma, pozitif SARS-CoV-2 polimeraz zincir reaksiyonu (PZR) takiben uygulanan KP dozlarının sayısının, immünoglobulin (Ig)G oranının gücünün ve KP uygulama süresinin 30 günlük hastane içi mortalite üzerinde bir etkisi olup olmadığını araştırmayı amaçladı. Gereç ve Yöntem Bu tek merkezli retrospektif çalışma, hastaneye yatırılan ve ciddi/kritik COVID-19 hastalığı kriterlerini karşılayan ve KP alan hastalarla yapılmıştır. Demografi, komorbiditeler, ek ilaçlar, semptomların başlangıcı, SARS-CoV-2 PZR testi ile hastaneye yatış arasındaki süre, ilk KP uygulamasının zamanı, laboratuvar sonuçları, solunum desteği ihtiyaçları, O2 satürasyonu, başlangıçtaki ateş, akut fizyolojik, kronik sağlık değerlendirmesi (APACHE) II skorları ve ardışık organ yetmezliği değerlendirmesi skorları kaydedildi. Bulgular Yaş ortalaması 64,2±14,5 (19-91) olan 224 hastanın 143’ü erkekti. En yaygın komorbiditeler hipertansiyon ve konjestif kalp yetmezliği idi. Kronik böbrek yetmezliği, mekanik ventilasyon ihtiyacı, PO2/FiO2

Drowning is a significant public health issue, particularly in coastal regions such as Sinop, Turkey, where seasonal variations contribute to a high incidence of cases. However, there is a lack of long-term, population-based studies from the Black Sea region, where distinct environmental factors may influence drowning patterns. This study provides a comprehensive 13-year analysis of seawater drowning cases, including detailed demographic, clinical, and outcome characteristics, to inform prevention strategies and improve emergency response. A retrospective, observational study was conducted on all patients admitted to the regional referral Emergency Department (ED) due to seawater drowning between July 2011 and July 2024. Demographic characteristics, clinical parameters, and outcomes were retrieved from institutional and national health record systems. Descriptive statistical analyses were performed. A total of 198 patients were included, of whom 69.2% were male, with a mean age of 29.6 years. The majority of cases (over 82%) occurred in July and August, and 51% involved tourists. Cardiopulmonary resuscitation (CPR) was performed in 17.7% of patients. Trauma was documented in 7.1% of patients; among these, the most commonly affected regions were the extremities (50.0%) and the head (35.7%). Laboratory analysis showed elevated lactate levels and reduced pH. On admission, most patients had preserved neurological status, while 19.2% presented with severe impairment (GCS ≤8). According to the Szpilman score, 37.9% had mild and 17.7% severe symptoms. The overall mortality was 19.7%, and 22.2% of patients required admission to the intensive care unit (ICU). Notably, 35.9% of all fatal cases (n = 14) involved individuals who drowned while attempting to rescue others. Drowning imposes a substantial burden in coastal regions, disproportionately affecting young males during the summer. Our findings highlight the need for enhanced emergency preparedness and structured clinical response, as well as public education on water safety and safe rescue practices. These findings contribute valuable insight for developing regional and international strategies to mitigate drowning outcomes. Not applicable. This study is a retrospective observational analysis and was not registered as a clinical trial.
