BACKGROUND
Vision loss resulting from thiamine deficiency is a recognized complication of bariatric surgery. Most patients with such vision loss have Wernicke encephalopathy with characteristic changes seen on neuroimaging. Other patients may have retinal hemorrhages, optic disc edema, and
A 23-year-old male with one month of intractable vomiting, subsequent cholecystitis status post cholecystectomy, and overall 40-pound weight loss over the last few months presented with altered mental status and seizures. MRI showed signal abnormalities involving the hypothalamus, periaqueductal
Twenty-three 2- to 5-month-old Beagle dogs were fed a purified thiamine-deficient ration (2 to 3 micrograms of thiamine/100 g of ration) at a rate of 40 to 70 g/kg of body weight/day depending on age. Eleven dogs were used as principles, 6 as pair-fed controls, and 6 as ad libitum-fed controls.
A 73-year-old male presented with new onset dizziness and a 22-kg weight loss due to antibiotic-induced nausea/vomiting. Due to gaze-evoked nystagmus (GEN), thiamine deficiency was suspected. Within 12 h after replacement, his GEN decreased.In patients with The neurologic form of beriberi has been described in multiple case reports following bariatric surgery for morbid obesity. Thiamine deficiency occurs due to marked emesis and/or altered absorption secondary to the reconfiguration of the gastrointestinal tract to achieve the malabsorption needed to
Women with persistent vomiting during pregnancy need early referral to appropriate health facilities. Delayed referral and inappropriate management may lead to metabolic encephalopathy from a variety of causes, including electrolyte derangements or thiamine deficiency (Wernicke's encephalopathy)
Wernicke's encephalopathy (WE) is a medical emergency. Although WE is commonly viewed in the context of alcoholism, it can be caused by thiamine deficiency secondary to persistent vomiting. Non-alcohol-related WE may be more catastrophic in onset and less likely to present with the classic features
BACKGROUND
Magnesium has a regulatory role in the excitability of cell membranes, and is also a cofactor in the phosphorylation of thiamine. Hypomagnesemia has been associated with coronary vasospasm, but its role in cerebrovascular pathology is controversial, and cerebral vasospasm exclusively
OBJECTIVE
To report a case of Wernicke's encephalopathy in a nonalcoholic woman with secondary hypoadrenalism.
METHODS
A 58-year-old Italian woman developed Wernicke's syndrome secondary to recurrent vomiting due to secondary hypoadrenalism.
RESULTS
Recurrent vomiting and resulting malnutrition
Patients suffering from nausea and vomiting of pregnancy (NVP) frequently do not receive therapy, in part because of fears of adverse effects of medications on the fetus. Several vitamin-based and herbal therapies have been shown to be effective and safe. Two randomized trials of vitamin B(6) have
Nausea and vomiting are both common in early pregnancy. Most cases are mild and do not require treatment. However, persistent vomiting and severe nausea can progress to hyperemesis if the woman is unable to maintain adequate hydration, and fluid and electrolyte as well as nutritional status are
A 24-year-old woman with a large cell anaplastic CD 30-positive T-cell non-Hodgkin's lymphoma (NHL) developed downbeat nystagmus, anisocoria, and oscillopsia. Prior to overt cerebral invasion by NHL, she had a thiamine deficiency with very low thiamine concentrations in the CSF, probably caused by
A prospective study was done to compare the efficacy of gastric emptying achieved by gastric lavage (GL) with that of ipecac-induced emesis (IE) in victims of drug overdose. Thiamine was used as a marker of recovery in gastric samples, as measured by ion exchange/ion pair high-performance liquid
Propionic acidemia is often manifested during the neonatal period with vomiting, failure to thrive, lethargy, and hyperammonemic coma when catabolism is prolonged. Mild lactic acidosis frequently accompanies metabolic decompensation. We present two patients with propionic acidemia whose initial
A 6-year-old dog, a 4-year-old dog and three 7-week-old puppies were diagnosed with thiamine deficiency caused by feeding sulphite treated meat. The 6-year-old dog presented with a history of inappetence, weight loss and vomiting that rapidly progressed to signs of multifocal intracranial disease
