Pyrrolizidine alkaloids (PAs) are natural phytotoxins found in thousands of plant species around the world. They are probably the most common poisonous plants affecting livestock, wildlife and humans. The disease occurs almost entirely as a consequence of chronic poisoning and in general ends fatally. In the present study, PAs poisoning was investigated in a gazelle with hepatic encephalopathy associated with severe neurologic signs. The main clinical signs included head pressing, progressive depression and weakness, ataxia and reluctance to move, turn the head to the left and to paddle, hyperesthesia and decreased food intake. Histopathological examination revealed major lesions in the liver consisting of severe hepatocyte megalocytosis and hypertrophy with nuclei enlargement, mild bile duct hyperplasia, centriacinar fatty change and hepatocellular necrosis. Moreover, pulmonary congestion and edema with endothelium necrosis and alveolar septa thickening, severe congestion in vessels of the brain and meninges, and myocardial necrosis were observed.

A 62-year-old female patient with a history of mastectomy surgery and sentinel lymphadenectomy in the context of breast cancer therapy was referred to our clinic for the treatment of refractory neuropathic pain. She reported a complex set of symptoms including burning and electrical-like sensations as well as profound hyperesthesia, hyperalgesia, and allodynia. The symptoms persisted chronically over months with a strong intensity and did not sufficiently respond to oral pain medication and co-analgetics, that is, tapentadol and pregabalin. As the patient could hardly move her right upper arm due to the pain, the quality of life was greatly reduced. In addition, the patient reported pain-related anxiety and depression. Therefore, a therapy with capsaicin 8% patch was initiated. Treatment with capsaicin 8% led to pain relief without tolerance development and improved flexibility in the affected body area. Despite significant pain relief, previous oral pain medications (tapentadol, pregabalin) as well as the anti-depressant amitriptyline were maintained to fully resolve pain symptoms, anxiety, and depression. In conclusion, capsaicin 8% may represent an effective therapeutic alternative for patients suffering from refractory neuropathic pain.
