AI Article Synopsis
- A 63-year-old man experienced severe blood loss during pancreatic surgery due to paroxetine causing platelet dysfunction, leading to thrombocytopathy.
- He lost 4 liters of blood and required multiple units of fresh frozen plasma and platelet concentrate for hemostatic control to continue the surgery.
- It's recommended to conduct thorough clotting tests for patients taking paroxetine before major surgeries to avoid complications related to bleeding.
Article Abstract
A 63-year-old man who took paroxetine for depression developed massive peroperative haemorrhage during a pancreaticoduodenectomy as a result of paroxetine-induced thrombocytopathy. He lost 4 litres of blood. After administration of 8 units of fresh frozen plasma and 2 times 5 units of thrombocyte concentrate, hemostatic control was obtained and the operation could be continued. Paroxetine is a non-tricyclic serotonin reuptake inhibitor prescribed for the treatment of depression. Since this drug also blocks serotonin reuptake in platelets, a clinically significant platelet dysfunction can occur under certain conditions. Because serotonin promotes platelet aggregation, too low an amount of serotonin in the platelets can result in thrombocytopathy. Before major surgery, it is advised to perform extensive clotting tests if there is any hint of haemorrhagic diathesis in the anamnesis. In case of a prolonged bleeding time, paroxetine treatment should be stopped perioperatively.

Background: The diagnosis of depression or anxiety treated by SSRIs has become relatively common in women of childbearing age. However, the impact of gestational SSRI treatment on newborn thyroid function is lacking. We explored the impact of gestational SSRI treatment on newborn thyroid function as measured by the National Newborn Screening (NBS) Program and identified contributory factors.

Objective: Sensory phenomena (SP) are aversive sensations driving repetitive behaviors in obsessive-compulsive disorder (OCD) and Tourette's disorder that are not well addressed by standard treatments. SP are related to the functioning of an interoceptive-sensorimotor circuit that may be modulated by the 5-HT receptor antagonist ondansetron. The present study employed an experimental medicine approach to test the effects of 4 weeks of high-dose ondansetron compared to placebo on SP severity and brain connectivity in a cohort of individuals with OCD and/or Tourette's disorder.

Fluoxetine (FLX), a typical selective serotonin reuptake inhibitors, has been frequently detected in aquatic environment and wild fish. However, little is known about its effect on thyroid endocrine system. In the present study, zebrafish (Danio rerio) embryos were exposed to 1, 3, 10, and 30 μg/L of FLX for 6 days.

Background And Aims: Probe-based confocal endomicroscopy (pCLE) allows real-time microscopic visualization of the intestinal mucosa surface layers. Despite remission achieved through anti-tumor necrosis factor or vedolizumab therapy, anomalies in the intestinal epithelial barrier are observed in inflammatory bowel disease (IBD) patients. Our study aimed to assess these abnormalities in non-IBD individuals and compare them with IBD patients in endoscopic remission to identify the associated factors.
