Peritoneal cavity circumference on computed tomography predicts outcomes in acute pancreatitis.

OBJECTIVES: We investigated the role of novel intra-abdominal parameters measured by computed tomography (CT) in the prediction of clinical outcomes in acute pancreatitis (AP). METHODS: Patients with AP underwent an abdominal CT scan on admission to define different intra-abdominal parameters (abdominal circumference, peritoneal cavity circumference, intraabdominal visceral fat area, and subcutaneous fat area) at the L2-L3 level using the open-source image analysis software Osirix Lite v.11.0.4 to predict clinical outcomes. RESULTS: Eighty patients with AP were analyzed. Peritoneal cavity circumference (PCC) was the only variable independently associated with outcomes. PCC showed an area under ROC for prediction of severity in AP of 0.830. A PCC ≥ 85 cm increased the risk of severity of AP (RR 15.7), persistent systemic inflammatory response syndrome (RR 9.3), acute peripancreatic fluid collection (RR 6.4), necrotizing pancreatitis (RR 21.50), and mortality (RR 2.4). We found a 4.7-fold increase in the risk of developing severe AP for each 10 cm increase in PCC. CONCLUSIONS: PCC measurement at the L2-L3 level using a non-enhanced abdominal CT scan on admission in patients with AP is useful in the early prediction of severity, persistent systemic inflammatory response syndrome, local complications, and mortality.

Neuropsychiatric symptoms in a patient with Dyke-Davidoff-Masson syndrome and systemic lupus erythematosus: a case report.

BACKGROUND: Dyke-Davidoff-Masson syndrome is an uncommon constellation of radiological and clinical findings. Few reports describe co-occurring psychiatric manifestations. Systemic lupus erythematosus is a systemic disease with vascular, neurologic, and psychiatric involvement. To the best of our knowledge, no case reports have been made associating these entities. CASE PRESENTATION: We present the case of a 21-year-old Mexican mestizo woman with a history of systemic lupus erythematosus diagnosed at 4 years of age, who developed focal impaired awareness seizures when she was 8-years old, which became treatment-resistant at age 15. Two years prior to our evaluation, she developed deep vein thrombosis; clinical and laboratory criteria were met to diagnose secondary antiphospholipid syndrome. After being treated with anticonvulsants, glucocorticoids, and immunosuppressants with only a partial response, she developed a severe major depressive episode 1 year prior to our assessment, including two suicide attempts. She was referred to the out-patient clinic of our department for evaluation; intellectual disability, depressive symptoms, and behavioral symptoms were documented. Imaging studies revealed structural abnormalities in the left cerebral hemisphere: cortical atrophy, enlargement of sulci and cisternal spaces, and hyperpneumatization of the frontal sinus. Treatment with an antidepressant was initiated and maintained for 1 year, added to anticonvulsants and immunosuppressants. Depressive and behavioral symptoms diminished and no suicidal ideation has been noted at follow-up. CONCLUSIONS: Dyke-Davidoff-Masson syndrome was diagnosed, accompanied by clinical symptoms previously reported as epilepsy and intellectual disability. This case report illustrates the complexity of syndrome presentation in an adult female, constituting a diagnostic and therapeutic challenge. This constellation of symptoms and structural brain abnormalities should be kept in mind in patients with neuropsychiatric manifestations and systemic diseases with central nervous system involvement, especially when diagnosed at a young age.
