- Congenital pancreas malformations: a clinical case reportPublication . Bento, A; Baptista, H; Oliveira, FJOBJECTIVE: This study aimed to review the congenital malformation known as agenesis of the dorsal pancreas (ADP) and other pancreatic birth defects, based on a rare and exemplary clinical case of pancreatic malformations. The intent was to review the latest information published in the national and international literature on pancreatic birth defects, and to investigate the diversity of clinical presentations of ADP and other congenital pancreas abnormalities. The purpose was to identify which situations have therapeutic indication, the most appropriate time to institute treatment, and the currently available medical or surgical treatment of pancreatic congenital malformations. RESULTS: ADP is a very rare malformation that occurs during organogenesis. In the last decades, a large volume of embryological and genetic information has been obtained, helping to understand the causes of pancreatic malformations, which must be studied and understood as a whole. CONCLUSION: Pancreatic malformations are infrequently studied causes of acute and chronic pancreatic in adults. The possibility of pancreatic malformations should always be considered in patients with acute or chronic pancreatitis with no evident cause.
- Endometriosis-induced intussusception of the caecal appendixPublication . Costa, M; Bento, A; Batista, H; Oliveira, FAppendicular intussusception is an uncommon entity, with a reported incidence of 0.01%. The diagnosis is difficult and often only performed at the time of surgery. Intussusception has multiple causes including tumours, foreign bodies and polyps. The definitive treatment is surgical, and the extent of resection is determined by the underlying pathology and degree of invagination. Endometriosis is a rare cause of appendicular intussusception, with 194 cases described in the English literature. We report a case of a 42-year-old woman who presented with chronic abdominal pain in the lower right quadrant. A mass at the caecum was identified during investigations for renal stones by CT. Colonoscopy showed a polypoid lesion, with presumed origin in the appendix. Ileocaecal resection was performed because an appendicular tumour was suspected. Pathological examination identified endometriosis of the appendix and associated peritoneum with invagination of the caecum. The patient was discharged 7 days after surgery and is currently asymptomatic.
- First report of chronic hepatitis E in renal transplant recipients in PortugalPublication . Breda, F; Cochicho, J; Mesquita, JR; Bento, A; Oliveira, RP; Louro, E; Nascimento, MS; Leitão, J; Gomes, HV; Carvalho, AHepatitis E virus (HEV) infection can be responsible for chronic hepatitis in immunocompromised patients, and can rapidly evolve into fibrosis and/or hepatic cirrhosis. We present two cases of chronic hepatitis E, emphasizing the need to be aware of this entity as a growing etiology of hepatitis in transplant and immunocompromised patients.
- Jejuno-jejunal invagination caused by epithelioid sarcoma: a case reportPublication . Bento, A; Baptista, H; Pinheiro, C; Martinho, FINTRODUCTION: Jejuno-jejunal invagination is a rare condition and is usually caused by a benign lesion. We describe the case of a patient with a jejunal epithelioid sarcoma. Epithelioid sarcoma is a rare histologic subtype of sarcoma and few cases have been published. CASE PRESENTATION: A 70-year-old Caucasian man presented with vomiting and anemia. A jejuno-jejunal invagination was diagnosed and the patient underwent surgery. An epithelioid sarcoma of the wall of the jejunum was found on the invaginated ansa. CONCLUSION: To the best of our knowledge, an epithelioid sarcoma has never been reported to arise at the wall of the proximal jejunum or to present with jejuno-jejunal invagination
