COVID-19-associated acute appendicitis in adults. A report of five cases and a review of the literature.

The novel coronavirus has negatively affected patients and healthcare systems globally. Individuals with coronavirus disease 2019 (COVID-19) experience a wide range of respiratory symptoms, from mild flu-like symptoms to severe and potentially fatal pneumonia. Some patients report gastrointestinal symptoms, such as nausea, vomiting and abdominal pain in addition to the respiratory symptoms or as a separate presentation. Even though abdominal pain syndrome indicates acute appendicitis, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection should be considered as a possible diagnosis during this pandemic. However, there have been reports of a few cases of acute abdominal pain revealing acute appendicitis associated with SARS-CoV-2 infection. Appendectomy is challenging in COVID-19-infected patients with acute appendicitis as it includes high surgical risks for the patients, as well as hazards for healthcare professionals who are exposed to SARS-CoV-2. The present study reports five cases of adult patients with COVID-19 with simultaneous acute appendicitis. In addition, the present study aims to provide the framework for the diagnosis and management of adult patients with COVID-19 with acute appendicitis.

Symptomatic ovarian involvement as the initial presentation of primary mediastinal large b-cell lymphoma.

Primary mediastinal large B- cell lymphoma (PMLBCL) is a mature aggressive B-cell lymphoma which affects mainly young and middle-aged women. The majority of patients present with bulky mediastinal lymphadenopathy. Extranodal involvement is a rare phenomenon at disease presentation. Herein, we describe a case of a young female with PMLBCL presenting with symptomatic, bulky ovarian involvement. The 23-year old patient presented at the Emergency Department with abdominal pain. The chest X-ray film revealed a mediastinal mass and CT scan revealed a large pelvic mass, possibly involving the ovaries. Due to the development of signs of acute abdomen, she was urgently transferred to the operation room where surgical resection of the right ovary and the adjacent mass was performed. The histological examination of the resected material revealed proliferation of PMLBCL cells. This is the first report in the scientific literature describing symptomatic ovarian mass as the initial mode of presentation of PMLBCL.

The rare entity of cholocystocolonic fistula: a case report.

Cholocystocolonic fistulas (CCFs) represent a rare medical entity. Previous inflammatory processes in the abdomen, especially in the gallbladder and surgeries are all related to their appearance. There are not typical findings concerning the clinical image and the therapeutic approach varies between patients. Herein, we present a case of a 46-year-old patient, with a history of perforated duodenal ulcer, suffering from abdominal pain and diarrheas. A computed tomography (CT) demonstrated air inside the biliary system. A laparotomy was conducted to the patient and no complications had occurred. In addition, a review of literature regarding the clinical presentation and the therapeutic options for this disease are discussed in this manuscript in relation to our patient.

Inflammatory Fibroid Polyp of the Gastrointestinal Tract: A Systematic Review for a Benign Tumor.

BACKGROUND/AIM: Inflammatory fibroid polyp (IFP) is a rare, usually solitary and intraluminal polypoid benign tumor that can affect any part of the gastrointestinal (GI) tract, although in the majority of cases it affects the stomach. This lesion is characterized by proliferation of highly vascular fibrous tissue and infiltration by a variable number of different inflammatory cells. Its etiology is unknown. Our aim was to describe all the reported data concerning IFP. MATERIALS AND METHODS: An extensive search of the PubMed Index was performed for publications with titles or abstracts containing the terms: "inflammatory fibroid polyp" with/without "Vanek". Results were filtered for publications in English and concerning only humans. One hundred and twenty-four publications were finally included in this review. RESULTS: IFP has a female predominance. It affects patients in their 5th decade of life, although there are cases of patients from 4 to 84 years of age. IFP usually affects the stomach and more specifically the gastric antrum but can be detected throughout the GI tract. A significant number of cases remain asymptomatic but the most frequent presentations of IFP are abdominal pain, acute abdomen and GI bleeding. Most cases are treated by endoscopic resection of the lesion. No recurrence nor IFP-specific complications have been reported. Histopathology of IFP varies. CONCLUSION: It is relatively safe to conclude that both the etiology and the timing of diagnosis might change the histopathology, immunohistological staining and tissue structure of IFP. Suggested theories should be taken into consideration with caution as the etiology and pathophysiological mechanisms of IFP are unknown.

Ethical Dilemma: Is it Worthwhile Operating an End-Stage Pancreatic Cancer Patient with Acute Mesenteric Artery Ischemia?

Pancreatic cancer is as an aggressive malignancy with low survival rates. We present the first case of an operation of acute mesenteric ischemia performed in a patient with end-stage pancreatic adenocarcinoma. Through this case, we also discuss raising concerns regarding the management of severe complications such as acute mesenteric ischemia in patients with progressed pancreatic carcinoma. How ethical is to leave patients untreated? The decisions for management of patients with advanced disease are strongly based on the expected quality of life, ethical principles, different religions and spiritualities, and the burden of healthcare cost.
