RESUMO

Melanoma is a very aggressive skin cancer that could metastasize to any organ in the body. The treatment of melanomas includes surgical resection, chemotherapy, and immunotherapy. After resections, melanomas could recur at the previous site or present as a distant metastatic lesion. The symptoms of melanoma are vague and primarily occur because of the local disruption of the tissue architecture. Presented here is a case of gastric melanoma that presented with abdominal discomfort and melena in a patient with a history of penile melanoma that was completely resected 3 years earlier. This case illustrates the importance of having metastatic lesions to the intestinal tract as a differential for a patient with gastrointestinal hemorrhage.

RESUMO

Acute esophageal necrosis (AEN) is a rare and often fatal pathology of unclear etiology affecting the distal two-thirds of the esophagus. Typically, elderly patients with multiple comorbidities present with signs of upper gastrointestinal (GI) hemorrhage. On endoscopy, the mucosa is black due to ischemic necrosis, resulting in the commonly used term "black esophagus." We present a rare case of a 61-year-old male presenting with shortness of breath and hematemesis diagnosed as AEN through endoscopy. This case illustrates the importance of considering AEN as part of differential diagnoses in a rising elderly population with multiple comorbidities that present with upper GI hemorrhage. Treatment should be aimed at maintaining hemodynamic stability with high-dose proton pump inhibitors.

RESUMO

BACKGROUND: Colorectal cancer is the third leading cause of cancer death; therefore early detection by screening is beneficial. Residents at a clinic in NJ, USA were not offering other forms of colon cancer screening when patients refused colonoscopy, which lead to the creation of the quality improvement project. METHODS: Residents practicing at the clinic were given an anonymous survey determining which method of colon cancer screening they used and which alternative method they offered when patients refused the original method. The residents were educated about all methods of colon cancer screening and the residents were resurveyed. RESULTS: A total of 64% of residents offered less invasive testing when colonoscopy was refused. Six months after education, 95% of residents offered less invasive testing when colonoscopy was refused. CONCLUSIONS: Early detection and removal of polyps by colonoscopy reduce the risk of cancer development. Colonoscopy is the gold standard for colon cancer screening; however other less invasive modalities are approved. This quality improvement project lead to offering the fecal immunochemical test or fecal occult blood test once patients refused colonoscopy at the clinic, increasing the number of patients receiving colorectal cancer screening, and thus providing better medical care.

RESUMO

Diabetes mellitus type 3c (DM3c) is an uncommon cause of diabetes due to pancreatic pathology. Its prevalence reaches about 5-10% among all diabetics in the Western world, largely due to chronic pancreatitis. DM3c occurs due to the destruction of the endocrine islet cells. Glucagon and insulin levels are both decreased due to the destruction of alpha and beta cells, respectively. This makes the development of diabetic ketoacidosis (DKA) a rare process in patients with DM3c because of the destruction of glucagon, which facilitates ketone production. We report a case of DM3c presenting with DKA. The patient presented with a history of chronic pancreatitis and was on pancreatic enzyme replacement therapy. Prior records revealed that HbA1c levels were normal. Prior computed tomography evidence revealed diffuse pancreatic calcifications. The patient was admitted for DKA, presenting with hyperglycemia, blood glucose of 703 mg/dL, bicarbonate of 16 mmol/L, ketones in the urine and acetone in the blood. The patient's anion gap corrected for albumin was 27. The patient was admitted to the medical intensive care unit where he was treated with intravenous (IV) insulin and IV hydration. Once the anion gap closed, the patient was transitioned to long-acting insulin. HbA1c level on admission was elevated, autoimmune causes of diabetes were sent and were negative, ruling out late onset type 1 diabetes. This shows that although it is a rare phenomenon, diabetics with DM3c can present in DKA.

RESUMO

Graviola (Annona muricata) is a small deciduous tropical evergreen fruit tree, belonging to the Annonaceae family, and is widely grown and distributed in tropical and subtropical regions around the world. The aerial parts of graviola have several functions: the fruits have been widely used as food confectionaries, while several preparations, especially decoctions of the bark, fruits, leaves, pericarp, seeds, and roots, have been extensively used in traditional medicine to treat multiple ailments including cancers by local communities in tropical Africa and South America. The reported therapeutic benefits of graviola against various human tumors and disease agents in in vitro culture and preclinical animal model systems are typically tested for their ability to specifically target the disease, while exerting little or no effect on normal cell viability. Over 212 phytochemical ingredients have been reported in graviola extracts prepared from different plant parts. The specific bioactive constituents responsible for the major anticancer, antioxidant, anti-inflammatory, antimicrobial, and other health benefits of graviola include different classes of annonaceous acetogenins (metabolites and products of the polyketide pathway), alkaloids, flavonoids, sterols, and others. This review summarizes the current understanding of the anticancer effects of A. muricata and its constituents on diverse cancer types and disease states, as well as efficacy and safety concerns. It also includes discussion of our current understanding of possible mechanisms of action, with the hope of further stimulating the development of improved and affordable therapies for a variety of ailments.
