- Primary Petit Hernia: From Diagnosis to Open Surgical ApproachPublication . Alves, Duarte Gil; Sousa, Jessica; Rodrigues, Catarina; Silva, Sara; Ribeiro, RómuloLumbar hernias are quite rare, even more so when primary or of spontaneous nature. These defects in the lumbar region demand a comprehensive knowledge of the anatomy of the lateral abdominal wall and paraspinal muscles. Given the proximity of bone structures, they can pose a surgical challenge when trying to achieve an ideal dissection and appropriate mesh overlap. The authors report the case of a primary Petit's hernia that underwent an open anterior surgical approach with the use of a preperitoneal mesh. In addition to the described surgical technique, the article also aims to detail the diagnosis and anatomic classification of this rare pathology.
- Uncommon Movement Disorders in Chronic Hepatic Disease with Response to RifaximinPublication . Sousa, Ana L; Salgado, Paula; Alves, José E; Silva, Sara; Ferreira, Sofia; Magalhães, MarinaBackground: Chronic hepatic disease can present with extrapyramidal symptoms. We describe two cases that presented with highly unusual movement disorders: ballism and gait freezing. Case report: Patient 1 is a 42-year-old man with previous episodes of hepatic encephalopathy (HE) who presented with upper limb dystonia and generalized chorea that progressed to ballism. Patient 2 is a 55-year-old woman who presented with pronounced gait freezing. In both patients, features of HE and acquired hepatocerebral degeneration coexisted. They improved markedly, though transiently, with rifaximin. Discussion: Ammonia-reducing treatments should be considered in patients presenting with movement disorders due to chronic liver disease.
