A case of benign multicystic peritoneal mesothelioma.

Benign Multicystic Peritoneal Mesothelioma (BMPM) is an exceedingly rare benign abdominal neoplasm with fewer than 200 cases reported worldwide. Owing to its rarity, vague clinical picture, and elusive causes, diagnosis is often delayed or missed. Histopathological examination and immunohistochemical staining are crucial for definitive diagnosis. However, due to lack of substantial literature, the standard of care and future prognosis remain subjects of inquiry. We present a case report of one female patient diagnosed with BMPM and treated with surgical resection.

Trends in liver profile and nutrition outcomes in children undergoing intestinal rehabilitation using a mixed lipid injectable emulsion.

BACKGROUND: Pediatric patients undergoing intestinal rehabilitation (IR) using parenteral nutrition (PN) are at higher risk for intestinal failure-associated liver disease (IFALD). Nutrition support, growth, and liver enzymes must be closely monitored while incorporating hepatoprotective lipid injectable emulsions for optimal patient outcomes. OBJECTIVE: Describe trends of liver profile and nutrition outcomes for pediatric patients undergoing IR using SMOFlipid[SO,MCT,OO,FO-ILE]). METHODS: After IRB approval, patients undergoing IR using SO,MCT,OO,FO-ILE were observed prospectively from January 1, 2017, through December 1, 2019. The following values were documented monthly: aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TB), triene/tetraene ratio (TTR), micronutrient and trace element levels, z-scores for growth, and nutrition support regimen. Values were compared. RESULTS: The group involved 16 pediatric patients for an average of 16.4 months on SO,MCT,OO,FO-ILE. By the end of the study, mean PN hours per day decreased by 34.7%, P < 0.0001. Mean PN calories per kilogram decreased from 60.4 to 48.3, P = 0.004. SO,MCT,OO,FO-ILE calories met the recommended dietary intake goal of 30% at the average 1.6 g/kg. Growth z-scores increased in those <2 YOA , although the body mass index decreased in our >2 YOA cohort. Total nutrition received from PN decreased to 62%: a 32% change, P = 0.001. There were no statistically significant changes in AST or ALT. TB decreased by 67.08%, P <0.05. No essential fatty acid deficiency was reported (TTR < 0.02). There were no changes in micronutrient and trace element deficiencies. There was zero new incidences of IFALD. CONCLUSIONS: SO,MCT,OO,FO-ILE may be used long term in pediatric patients while promoting growth and development.

Hepatocellular Carcinoma With Tumor Thrombus to the Hepatic Veins and the Right Atrium: A Case Report and Review Exploring Various Presentations and Treatment Options.

Hepatocellular carcinoma (HCC) is a leading cause of cancer and cancer-related deaths in the world. Some of the risk factors for the development of HCC include Hepatitis B virus (HBV), Hepatitis C virus (HCV), chronic alcoholism, autoimmune hepatitis, among others. One manifestation of HCC includes tumor thrombus (TT) to the right atrium (RA), which occurs in 0.67-4.1% of patients with HCC. Our case focuses on a unique presentation of HCC with RA TT with initial symptoms of nausea and vomiting without signs of cardiac decompensation or hemodynamic instability. Although there is no definitive treatment for TT to the RA, there are a variety of proven avenues of management of HCC TT to the RA, especially pertaining to patients with adequate liver function. A 63-year old female with a past medical history of untreated HCV and alcohol abuse with no previously known liver disease or history of liver decompensation, presented with nausea, vomiting, and diarrhea. Initial labs revealed hypovolemic hyponatremia and transaminitis with negative ethanol levels. The model for end-stage liver disease (MELD-Na) score was calculated at 27, and she had a Child-Pugh class C score. Follow up labs were significant for elevated alpha-fetoprotein (AFP). Triple-phase CT of the liver revealed a large liver mass with extension into the RA with TT and necrosis of the liver. An echocardiogram revealed a RA mass versus thrombus. Throughout her hospitalization, she never admitted to cardiac symptoms, including shortness of breath, palpitations, or chest pain. No tachycardia was noted, and her blood pressure remained stable. She was not a candidate for surgery or chemotherapy. The patient declined any heroic measures, and palliative care was consulted for further management. She was transferred to hospice, where she died one week later.  There are numerous etiologies and clinical presentations of HCC with TT to the RA. Its disease course is insidious and may not present as symptomatic until there is a sizable tumor burden. Therefore, treatment options for HCC with TT to the RA are reliant on HCC screening for at-risk populations, early diagnosis, and each individual patient's baseline liver function.
