Gastroduodenal Involvement in AL Amyloidosis: Case Report and Literature Review.

Gastrointestinal amyloidosis is a rare condition commonly found in the setting of systemic AL amyloidosis. Amyloid can deposit throughout the gastrointestinal tract and the resulting symptoms vary depending on the site of deposition. Gastrointestinal (GI) manifestations can range from weight loss or abdominal pain, to more serious complications like gastrointestinal bleeding, malabsorption, dysmotility, and obstruction. This case describes a patient with known history of IgG lambda AL amyloidosis, presenting with epigastric pain and unintentional weight loss found to have gastroduodenal amyloidosis. The definitive diagnosis of GI amyloidosis requires endoscopic biopsy with Congo red staining and visualization under polarized light microscopy. There are currently no specific guidelines for the management of GI amyloidosis. Generally, the goal is to treat the underlying cause of the amyloidosis along with symptom management. Our patient is being treated with cyclophosphamide, bortezomib, and dexamethasone (CyBorD) and started on hemodialysis due to progression of renal disease.

Conservative Management of Duodenal Penetration by Inferior Vena Cava Filter: Case Report and Review.

Duodenal penetration is a late complication associated with the placement of inferior vena cava (IVC) filters. In this case report, we are presenting a case of asymptomatic duodenal penetration by IVC filter that was managed conservatively.

Recurrent acute-onset of chronic inflammatory demyelinating polyneuropathy after COVID-19 vaccination.

This is the case of 54-year-old male with a past medical history of Chronic Inflammatory Demyelinating Polyneuropathy (CIPD) who was found to have an acute exacerbation of CIPD shortly after receiving his 1st COVID 19 booster (3rd dose of vaccination series) and was successfully treated with intravenous immunoglobulin (IVIG) and then was found to have another acute exacerbation of CIDP 6 months later after receiving his 2nd COVID 19 booster (4th dose of vaccination series) that required intubation and long term tracheostomy. CIPD is an acquired immune-mediated polyneuropathy that mainly affects the peripheral nerve roots nerves. It typically presents with relapsing/remitting, or progressive symmetrical muscle weakness and sensory involvement and can cause decreased respiratory effort. COVID-19 is mainly a respiratory disease, but it has been associated with a wide variety of neurological conditions. Although there have been several findings of acute inflammatory demyelinating polyneuropathy in association with COVID-19, CIDP exacerbation as a result of COVID-19 has rarely been seen in the literature. Furthermore, CIDP exacerbation as a result of COVID-19 vaccination is even less frequently seen.

Epidemiology of Gastric Cancer: Global Trends, Risk Factors and Premalignant Conditions.

This review article aims to provide a comprehensive overview of recent epidemiology, pathogenesis, risk factors, and premalignant conditions of gastric cancer. Worldwide, gastric cancer is one of the most common and most fatal cancers. The incidence and mortality remain high in regions such as East Asia and Eastern Europe. Although there is a lower incidence in the United States, it remains a deadly disease. Age, gender, and race are non-modifiable demographic risk factors for developing gastric cancer. There have been several dietary and lifestyle risk factors such as salt preserved foods, N-nitroso compounds containing foods, tobacco smoke, alcohol use, and obesity that have been shown to contribute to the development of gastric cancer. Infections have additionally been shown to have a clear role in the pathogenesis of gastric cancer as Helicobacter pylori eradication has shown a significant reduction in the incidence of gastric cancer as well as other pathogens such as Epstein-Barr virus. There are certain premalignant lesions that increase the risk of developing gastric cancer. These include atrophic gastritis, and intestinal metaplasia amongst others.

Stomach Within a Large Inguinal Hernia.

We are reporting a case of massively enlarged left inguinal hernia containing the stomach and presenting with coffee ground emesis. Esophagogastroduodenoscopy (EGD) identified a non-ischemic stomach with three small gastric ulcers. The patient opted for non-surgical management.

Pyloric Stenosis: A Rare Manifestation of Crohn's Disease.

We are presenting a rare case of pyloric stenosis due to Crohn's disease. A 53-year-old woman with prior history of colonic Crohn's disease was admitted to the hospital with gastric outlet obstruction. Esophagogastroduodenoscopy demonstrated pyloric stenosis and biopsy was consistent with Crohn's disease. She was treated with corticosteroids and her condition improved.

COVID-19-Associated Ischemic Colitis: A Rare Manifestation of COVID-19 Infection-Case Report and Review.

Following the first report of COVID-19 infection in December 2019 as a respiratory illness, it has proven to be a multisystem disease. There are few reported cases of ischemic colitis with COVID-19 infection in the medical literature to date and we have limited understanding of its pathophysiology. We report 2 cases of ischemic colitis as the only manifestation of COVID-19. In addition, we review the current limited literature regarding COVID-19-associated ischemic colitis.

An Exceedingly Rare Case of Liraglutide-Induced Liver Injury.

Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist used for the treatment of type 2 diabetes mellitus. We are reporting the second case of liraglutide-induced liver injury, with complete resolution of liver injury after discontinuation of the drug.

Metastatic Gastric Cancer to the Colon.

Gastric cancer is one of the most common and deadly cancers worldwide, especially amongst older males. Current data suggest gastric cancer is the fifth most common neoplasm and the third most deadly cancer, with an estimated 783,000 deaths in 2018. Risk factors associated with the development of gastric cancer include obesity, gastroesophageal reflux disease, Helicobacter pylori infection, and low socioeconomic status. Diagnosis of gastric cancer can be accomplished by endoscopy, which allows the clinician to obtain a biopsy specimen. Endoscopic ultrasound is also an important modality that is helpful in assessing tumor invasion. The most common sites of metastatic gastric cancer in descending order are the liver, peritoneum, lung and bone. Rarely will gastric cancer metastasize to the colon. Here we present a rare case of colonic metastasis of a primary gastric adenocarcinoma.

Esophagitis Dissecans Superficialis (EDS) Secondary to Hair Dye Ingestion: Case Report and Literature Review.

Esophagitis dissecans superficialis (EDS) is a rare and underdiagnosed esophageal lesion characterized by sloughing of the esophageal mucosa that has been associated with medications, various autoimmune disorders, and exposure to some chemical irritants. Anatomically, EDS is most commonly seen in the middle and distal thirds of the esophagus. When present, EDS is best treated by discontinuing the offending agent and initiating pharmacologic therapy with proton pump inhibitors. Steroids may also be effective if the etiology is autoimmune in nature. Our case highlights a 65-year-old female diagnosed with EDS after incidental ingestion of hair dye containing resorcinol and para-phenylenediamine (PPD).
