A 34-year-old woman presented with worsening generalized swelling and breathlessness for four months; physical examination showed pallor, diffuse anasarca, and bilateral crackles on respiratory auscultation. Laboratory investigations showed severe hypoproteinemia, fat malabsorption with fat-soluble vitamin deficiency, and significant protein loss in the stool. Imaging studies revealed pulmonary edema, ascites, bowel wall edema, and a duodenal polyp. Further evaluating the duodenal polyp, a grade two duodenal neuroendocrine tumor (NET) was identified. She was managed with subcutaneous octreotide and duodenal polypectomy, resulting in significant clinical improvement. This case highlights the importance of diagnosing and managing protein-losing enteropathy secondary to gastric neuroendocrine tumors.

We present a life-threatening case of postpartum acute necrotizing pancreatitis. The patient is a 37-year-old female with no past medical history who delivered a healthy baby boy via cesarean section. Twenty days later, she presented to the emergency department with acute onset of nausea, non-bloody vomiting, abdominal bloating, and epigastric pain radiating to the back. Less than 24 hours later, she progressed into septic shock despite aggressive resuscitation, requiring vasopressor support in the ICU. Initial CT imaging showed multiple patchy hypodensities throughout the pancreas consistent with severe necrotizing pancreatitis. Her hospitalization was further complicated by difficulty obtaining source control of her infection, Clostridium difficile, and nutritional deficiencies that resulted in gross anasarca. She was discharged from the hospital on day 59 after undergoing multiple percutaneous drain placements, IV antibiotics, and endoscopic gastrocystostomy with four pancreatic necrosectomies. Since discharge, the patient has required readmission twice for complications from her pancreatitis.

UNASSIGNED: Physicians must be alert for the exocrine pancreatic insufficiency diagnosis through the follow-up of postgastrectomy patients, regardless the severity and lag time. Urgent albumin and pancreatic enzyme replacement should be considered when diagnosed.
UNASSIGNED: It is documented that exocrine pancreatic insufficiency (EPI) can develop after gastrectomy. Steatorrhea, malnutrition, and weight loss are common symptoms of the disease; however, it is usually mild to moderate postgastrectomy. This article reports a case of EPI manifested by hypoalbuminemia leading to dyspnea and anasarca, which are not typical symptoms of postgastrectomy EPI. A 61-year-old man with a history of gastric adenocarcinoma treated by total gastrectomy and chemoradiotherapy was admitted to the hospital with dyspnea and anasarca. Despite being diagnosed as a case of malignancy recurrence in another hospital, based on the symptoms described, no evidence of malignancy was found. His ascites and pleural effusion were determined to be caused by hypoalbuminemia. In addition, he claimed steatorrhea, and his stool elastase was lower than expected. EPI was diagnosed based on his medical history, paraclinical tests, and examinations. He remained asymptomatic for 1 year after being treated with albumin and pancreatic enzymes. Postgastrectomy EPI may be severe enough to cause steatorrhea or hypoalbuminemia. Hence, regardless of the severity of the presentation, physicians must be alert for this diagnosis throughout the follow-up of patients with a history of gastrectomy. Urgent albumin and pancreatic enzyme replacement should be considered when diagnosed.

The definitive role of viral infections, such as rotavirus, in causing Kawasaki disease (KD) remains uncertain. However, the intriguing observation of concomitant rotavirus infection and KD suggests a potential association. This study aimed to investigate this relationship. We reported a case of concomitant KD and rotavirus infection complicated by hyponatraemia and anasarca. For the systematic review, we used three large databases, namely PubMed, Ovid, and Scopus, to search articles with the terms \"Kawasaki\" and \"rotavirus\". We also used Google Scholar as our secondary source. We included articles that fulfilled the following criteria: (i) articles reporting on children aged 18 and below; (ii) articles reporting on patients infected with rotavirus prior to or concomitant with KD; and (iii) articles written in English only. Three articles were included and analysed in combination with our reported patient. All patients exhibited gastrointestinal symptoms, including diarrhoea and vomiting, in addition to non-resolving fevers, which eventually manifested more signs and symptoms to support the diagnosis of KD. Stool samples from all patients revealed positive rotavirus antigens. Two patients (n = 2) were noted to have hyponatraemia and hypoalbuminaemia. Three (n = 3) manifested coronary artery abnormalities (CAA). Even though the relationship is not fully understood yet, it is known that the combination of these two pathologies can cause catastrophic immune responses and complications.

Behçet\'s disease (BD) is a systemic vasculitis which is most often manifested by recurrent oral aphthosis, genital aphthosis, and ocular involvement with sometimes visceral damage, in particular neurological, digestive, vascular, or renal. We report the case of a 21-year-old man admitted for anasarca who revealed severe cardiac involvement associating endomyocardial fibrosis, intracardiac thrombi and involvement of the tricuspid valve in the context of BD diagnosed a posteriori. Cardiac involvement is exceptional during BD, especially as a mode of entry into the disease. It can be particularly severe, hence the need for early diagnosis, rapid and sometimes aggressive management. Close monitoring is also necessary in order to watch for the occurrence of visceral manifestations, particularly in young patients.

BACKGROUND: Juvenile Dermatomyositis (JDM) is an autoimmune disease that typically presents with classic skin rashes and proximal muscle weakness. Anasarca is a rare manifestation of this disease and is associated with a more severe and refractory course, requiring increased immunosuppression. Early recognition of this atypical presentation of JDM may lead to earlier treatment and better outcomes.
METHODS: We present two female patients, ages 11 years old and 4 years old, who presented to the ED with anasarca and were subsequently diagnosed with JDM. Both patients required ICU-level care and significant immunosuppression, including prolonged courses of IV methylprednisolone, IVIG, and Rituximab.
CONCLUSIONS: Anasarca is a rare presentation of Juvenile Dermatomyositis, but it is important for clinicians to recognize this manifestation of the disease. Early recognition and treatment will lead to better outcomes in these children and hopefully decrease the need for prolonged hospitalization and ICU level care.

Collagenous colitis (CC) is associated with non-bloody, watery diarrhea, which is pathophysiologically reasonable because normal colonic absorption (or excretion) of water and electrolytes can be blocked by the abnormally thick collagen layer in CC. However, CC has also been associated with six previous cases of protein-losing enteropathy (PLE), with no pathophysiologic explanation. The colon does not normally absorb (or excrete) amino acids/proteins, which is primarily the function of the small bowel. Collagenous duodenitis (CD) has not been associated with PLE. This work reports a novel case of CD (and CC) associated with PLE; a pathophysiologically reasonable mechanism for CD causing PLE (by the thick collagen layer of CD blocking normal intestinal amino acid absorption); and a novel association of PLE with severe COVID-19 infection (attributed to relative immunosuppression from hypoproteinemia, hypoalbuminemia, hypogammaglobulinemia, and malnutrition from PLE).

Mirror syndrome or Ballantyne syndrome is a rare disease, characterized by the association between fetal anasarca and maternal generalized edema. This may be complicated by pre-eclampsia. The purpose of this study was to highlight the diagnostic and therapeutic features of this severe clinical entity, which, despite its rarity, should be suspected. We here report the clinical case of a 35-year-old parturient woman at 26 weeks of amenorrhea presenting to the Emergency Department with idiopathic mirror syndrome whose progression was rapidly marked by the occurrence of intrauterine fetal death and remission of maternal clinical-biological symptoms, once uterine vacuity was obtained. Indeed, a specific treatment in uterus is necessary, although in some severe idiopathic cases, only uterine vacuity can improve maternal and fetal prognosis.

Background: Immunotherapy has revolutionized the treatment of cancer, but this has not come without a cost. Although immune checkpoint inhibitors are less toxic than conventional chemotherapy, they are associated with more frequent autoimmune side effects. Case presentation: We report a case of a patient with metastatic renal cell carcinoma who was treated with nivolumab and subsequently developed treatment related hypothyroidism with consequent rhabdomyolysis. Treatment with thyroxine resulted in resolution of the symptoms. Because of normal thyroid function tests before initiating nivolumab therapy and the absence of any other causes of hypothyroidism, it was safe to extrapolate a causal relationship between nivolumab and hypothyroidism. To date, this is the first reported case of a programmed cell death-1 inhibitor causing hypothyroidism, severe enough to induce rhabdomyolysis. Conclusion: Patients on nivolumab and other PD-1 inhibitors should be monitored and screened regularly for immune-related adverse events.
