Although hyperthyroidism arising from primary thyroid disease is rare in pregnancy, transient gestational hyperthyroidism is not uncommon. This condition can be associated with hyperemesis gravidarum (HG), and Wernicke's encephalopathy. We present the case of a woman with toxic nodular goiter complicating HG-associated Wernicke's encephalopathy. A 38-year-old Caucasian woman, who had received a diagnosis of hyperthyroidism and HG early in her pregnancy, had intrauterine fetal death at Week 16 of gestation. One day after undergoing therapeutic abortion, she was admitted to our clinic with persistent thyrotoxicosis, nausea, and vomiting. A toxic thyroid nodule was detected. She was given antithyroid medication, total parenteral nutrition. On Day 10 of hospitalization, she developed ataxia, aphasia, and somnolence. Cranial magnetic resonance imaging showed increased bilateral thalamic signalization. She was given a diagnosis of Wernicke's metabolic encephalopathy, for which she received thiamine and multivitamin preparations. She responded dramatically on the second day of thiamine therapy. Her consciousness improved rapidly and she began to speak. Her muscle tone was slightly weak and she had paresthesias in both legs. Absorption of thiamine may be particularly impaired in pregnant women with hyperemesis and hyperthyroid disease. Wernicke's encephalopathy should be considered in hyperthyroid women with HG who develop neurological abnormalities.

Wernicke's encephalopathy occurs due to thiamine (vitamin B1) deficiency which is characterized by occulomotor dysfunction, confusion and ataxia. Although it is most common with alcoholism, can also be seen due to hyperemesis caused by chemotherapy, Crohn's disease, gastrointestinal system surgery, AIDS, bariatric surgery and longterm feeding with parenteral nutrition. In this case, a 51-year-old woman who was treated with longterm total parenteral nutrition due to hyperemesis and had the diagnosis of Wernicke's encephalopathy after admission to the intensive care unit is presented.

Wernicke's encephalopathy (WE) is a disease caused by thiamine deficiency related to alcoholism, hyperemesis, or thiamine malabsorption. The clinical manifestations of WE are mental change, ataxia, and ophthalmoplegia. The typical magnetic resonance imaging (MRI) findings of WE are symmetrical involvement of medial thalamus, periventricular region of the third ventricle, periaqueductal area, and mammillary body. The atypical MRI findings are more common in nonalcoholic WE. Since the increasing population of obesity and the preference of weight loss surgery, the risk of developing thiamine deficiencies associated with weight loss surgery has become a considerable etiology of WE. We herein reported a case reminds clinicians that WE can be a possible diagnosis in patient who developed acute altered mental status with atypical MRI lesion involving bilateral centrum semiovale and corona radiata after receiving bariatric surgery.

Wernicke encephalopathy is a neurological disorder, clasically characterized by altered consciousness, ophtalmoparesis, and ataxia results from tiamin deficiency. It is frequently associated with chronic alcohol abuse; however, many conditions which lead to thiamine deficiency such as gastric surgery, hyperemesis, parenteral nutrition, malnutrition may also be the cause. WE is a life-threatening condition that requires early diagnosis and rapid initiation of intravenous thiamin therapy. In patients, findings of characteristic examinations may not always be seen; therefore, imaging methods are of great importance. In this article, we aimed to emphasize the similar and different aspects of three WE cases with typical and atypical imaging findings.

Cannabis is one of the most widely used recreational drugs in the world. Tetrahydrocannabinol (THC) is the psychoactive principal constituent of the cannabis plant (Cannabis sativa). It is taken either orally or by inhalation, resulting in sedation, euphoria, relaxation and loss of social inhibition. Adverse effects from higher doses can include fear, distrust and a profound state of unease, hallucinations, ataxia, stupor and seizures. Long-term use can result in respiratory and cardiovascular toxicity and has been associated with a range of psychiatric conditions. Cannabinoid hyperemesis syndrome can occur with chronic use. Driving under the influence of THC is associated with approximately double the risk of motor vehicle crashes. The intensity and duration of symptoms is proportional to the concentration of THC in the blood. Following acute use, THC only remains in the blood for several hours before it is converted into a carboxylic derivative of THC and this partitions into the fat, from where it leaches out and can be detected in urine for weeks after use. Treatment of acute intoxication mainly consists of appropriate symptom-directed supportive care. Children are more susceptible to cannabis toxicity, particularly seizures and coma, and therefore may require additional supportive care for these potential symptoms. The aim of this narrative review is to provide a brief overview of the acute and chronic effects of cannabis, its pharmacokinetics, toxicity and the medical management of intoxication.
