Abstract
A case is presented, where preoperative malnutrition was the most likely explanation to elevated lactate levels during and after surgery. Poor circulation, a common cause of elevated lactate during surgery, was excluded. The elevated lactate levels were normalized after intravenous administration of thiamine. Thiamine is an essential cofactor in carbohydrate metabolism for energy production. Thiamine deficiency is common among ICU patients. Clinical suspicion of malnutrition should lead to early parenteral administration of thiamine without specific laboratory confirmation of thiamine deficiency.

Abstract
BACKGROUND Patients with suspected thiamine deficiency should receive treatment with parenteral thiamine to achieve the high serum thiamine levels necessary to reverse the effects of deficiency and to circumvent problems with absorption common in the medically ill. OBJECTIVE To quantify rates of parenteral administration of thiamine across university-affiliated hospitals and to identify factors associated with higher rates of parenteral prescribing. DESIGN Multicenter, retrospective observational study of thiamine prescriptions. METHODS Prescriptions for thiamine were captured from computerized pharmacy information systems across participating centers, providing information concerning dose, route, frequency, and duration of thiamine prescribed from January 2010 to December 2011. SETTING Fourteen university-affiliated tertiary care hospitals geographically distributed across Canada, including 48,806 prescriptions for thiamine provided to 32,213 hospitalized patients. RESULTS Parenteral thiamine accounted for a statistically significant majority of thiamine prescriptions (57.6%, P < 0.001); however, oral thiamine constituted a significant majority of the total doses prescribed (68.4%, z = 168.9; P < 0.001). Protocols prioritizing parenteral administration were associated with higher rates of parenteral prescribing (61.3% with protocol, 45.8% without protocol; P < 0.001). Patients admitted under psychiatry services were significantly more likely to be prescribed oral thiamine (P < 0.001). CONCLUSIONS Although parenteral thiamine accounted for a statistically significant majority of prescriptions, oral thiamine was commonly prescribed within academic hospitals. Additional strategies are needed to promote parenteral thiamine prescribing to patients with suspected thiamine deficiency.

Abstract
Wernicke encephalopathy is an acute neuropsychiatric disease with heterogeneous symptoms, including changes in mental status, ataxia and ocular abnormalities; if left untreated, these symptoms can lead to morbidity and even to mortality. The treatment is thiamine suppletion. Because of the heterogeneity of the symptoms and the high risk of morbidity and mortality if the symptoms are not treated, it is vitally important that on observing a patient's early symptoms the clinician immediately suspects that the symptoms could point to Wernicke encephalopathy.

Abstract
A 72-year-old woman became profoundly hypotensive and hypothermic 10 hours after undergoing a panniculectomy. She remained critically ill despite aggressive intensive care, and a diagnosis was not identified despite multiple consultations, imaging, and exploratory laparatomy. No improvement was seen until a large dose of intravenous thiamine alone was administered, dramatically restoring a normotensive and normothermic state. Although few cases of thiamine deficiency have been described in the context of plastic and reconstructive surgery, this case emphasizes the importance of considering this potentially fatal condition, which often does not manifest classically in the early postoperative period.

Abstract
BACKGROUND In a recent study one third of Lao patients presenting with uncomplicated Plasmodium falciparum malaria had biochemical evidence of thiamin deficiency, which was associated with a higher incidence of adverse events. Thiamin supplementation might, therefore, reduce adverse events in this population. METHODS An exploratory, double-blind, parallel group, placebo-controlled, superiority trial of thiamin supplementation in patients of all ages with uncomplicated and severe falciparum malaria was conducted in Xepon District, Savannakhet Province, southern Laos. Patients were randomly assigned to either oral thiamin 10 mg/day for 7 days immediately after standard anti-malarial treatment then 5 mg daily until day 42, or identical oral placebo. RESULTS After interim analyses when 630 patients (314 in thiamin and 316 in placebo groups) had been recruited, the trial was discontinued on the grounds of futility. On admission biochemical thiamin deficiency (alpha ≥ 25%) was present in 27% of patients and 9% had severe deficiency (alpha > 31%). After 42 days of treatment, the frequency of thiamin deficiency was lower in the thiamin (2%, 1% severe) compared to the placebo (11%, 3% severe) groups (p < 0.001 and p = 0.05), respectively. Except for diarrhoea, 7% in the placebo compared to 3% in the thiamin group (p = 0.04), and dizziness on day 1 (33% vs 25%, p = 0.045), all adverse events were not significantly different between the groups (p > 0.05). Clinical, haematological, and parasitological responses to treatment did not differ significantly between the two groups. CONCLUSION Thiamin supplementation reduced biochemical thiamin deficiency among Lao malaria patients following anti-malarial drug treatment, but it did not reduce the frequency of adverse events after anti-malarial therapy or have any detected clinical or parasitological impact.

Abstract
Although allergic side effects due to parenteral thiamine are well-documented, they are extremely rare when thiamine is used orally. We report a case of a 47-year-old woman who developed angioneurotic oedema secondary to oral ingestion of thiamine at a therapeutic dose. The incident occurred twice with a clear temporal relationship to the initiation on thiamine.

Abstract
Wernicke-Korsakoff syndrome is a condition with high morbidity and mortality and occurs as a consequence of thiamine deficiency. Clinical symptoms are often ambiguous and post-mortem examinations show that the syndrome is underdiagnosed and probably undertreated. There is sparse clinical evidence concerning optimal dosage and duration of treatment. This article reviews the current literature and concludes that all patients with a history of alcohol abuse should be treated with high dosage IV thiamine for an extended period of time, albeit further research is needed.

Abstract
CONTEXT Acute pancreatitis can lead to prolonged fasting and malnutrition. Many metabolic changes, including thiamine deficiency, may lead to the well know pancreatic encephalopathy. In this condition however the thiamine deficiency is rarely suspected. CASE REPORT We report the case of a 17-year-old woman with severe acute pancreatitis who developed mental status changes and ophthalmoplegia. A magnetic resonance image showed hyperintensive signals in periventricular areas, medial thalamus, and mammillary bodies, findings consistent with the diagnosis of Wernicke encephalopathy. Thiamine treatment reversed neurological complications. CONCLUSION Wernicke encephalopathy secondary to thiamine deficiency should be considered as a possible cause of acute mental status changes in patients with acute pancreatitis and malnutrition. Prophylactic doses of thiamine could be considered in susceptible patients.

Abstract
PURPOSE OF REVIEW To summarize the properties of thiamine and evaluate current evidence on thiamine status and supplementation, for different populations of critically ill patients. RECENT FINDINGS Thiamine, in the form of thiamine pyrophosphate, is a critical co-factor in the glyocolysis and oxidative decarboxylation of carbohydrates for energy production. Different studies have shown that critical illness in adults and children is characterized by absolute or relative thiamine depletion, which is associated with an almost 50% increase in mortality. Thiamine deficiency should be suspected in different clinical scenarios such as severe sepsis, burns, unexplained heart failure or lactic acidosis, neurological disorder in patients with previous history of alcoholism, starvation, chronic malnutrition, long-term parenteral feeding, hyperemesis gravidarum, or bariatric surgery. Nonetheless, thiamine supplements are not routinely given to critically ill patients. Clinicians should be able to suspect and recognize risk factors for the occurrence of severe neurological disorders secondary to thiamine deficiency, as early treatment can prevent the appearance of permanent neurological damage. SUMMARY Symptoms and signs associated with thiamine deficiency lack sensitivity and specificity in critically ill patients. Consequently, depletion is frequently unrecognized and underdiagnosed by clinicians. Potentially deleterious consequences of thiamine depletion should be avoided by early and appropriate supplementation.

Abstract
BACKGROUND Management of problem drinking presents the general practitioner with similar challenges and rewards to those associated with the management of other chronic conditions. OBJECTIVE This article presents a framework for managing alcohol problems in general practice based on national guidelines for the treatment of alcohol problems. DISCUSSION General practitioners are well placed to undertake the management of drinking problems following an assessment of the amount of alcohol taken and the risks this poses for the individual and the people around them. This assessment starts the process of engagement and reflection on drinking habits and will inform the appropriate management approach. Brief interventions can result in reduction in drinking in nondependent drinkers. For dependent drinkers, treatment steps include assessing need for withdrawal management and developing a comprehensive management plan, which includes consideration of relapse prevention pharmacotherapy and psychosocial interventions. The patient's right to choose what they drink must be respected, and those who continue to drink in a problematic way can still be assisted, with compassion, within a harm reduction framework.

Abstract
Thiamine (vitamin B1) is an essential component of a number of metabolic pathways and thiamine deficiency results in a progressive encephalopathy in both humans and animals. Confirming thiamine deficiency is problematic and relies on demonstrating reduced red blood cells transketolase activity, or indirect methods including urinary organic acid analysis and dietary analysis. The characteristic and selective vulnerability of different brain regions in carnivores has been demonstrated by magnetic resonance (MR) imaging in the dog and cat as an aid to diagnosis. A 2-year-old, female, domestic shorthair cat was presented with an acute onset of seizures and ataxia. MR imaging was consistent with thiamine deficiency and supplementation resulted in a progressive clinical improvement. Repeated MR imaging 4 days after starting thiamine supplementation revealed near complete resolution of the MR abnormalities. Repeated MR imaging following appropriate therapy may be useful to further confirm thiamine deficiency.

Abstract
Wernicke encephalopathy (WE), a neurological disorder caused by thiamine deficiency (TD), is characterized by structural damage in brain regions that include the thalamus and cerebral cortex. The basis for these lesions is unclear, but may involve a disturbance of glutamatergic neurotransmission. We have therefore investigated levels of the astrocytic glutamate transporters EAAT1 and EAAT2 in order to evaluate their role in the pathophysiology of this disorder. Histological assessment of the frontal cortex revealed a significant loss of neurons in neuropathologically confirmed cases of WE compared with age-matched controls, concomitant with decreases in alpha-internexin and synaptophysin protein content of 67 and 52% by immunoblotting. EAAT2 levels were diminished by 71% in WE, with levels of EAAT1 also reduced by 62%. Loss of both transporter sites was confirmed by immunohistochemical methods. Development of TD in rats caused a profound loss of EAAT1 and EAAT2 in the thalamus accompanied by decreases in other astrocyte-specific proteins. Treatment of TD rats with N-acetylcysteine prevented the downregulation of EAAT2 in the medial thalamus, and ameliorated the loss of several other astrocyte proteins, concomitant with increased neuronal survival. Our results suggest that (1) loss of EAAT1 and EAAT2 glutamate transporters is associated with structural damage to the frontal cortex in patients with WE, (2) oxidative stress plays an important role in this process, and (3) TD has a profound effect on the functional integrity of astrocytes. Based on these findings, we recommend that early treatment using a combination of thiamine AND antioxidant approaches should be an important consideration in cases of WE.

Abstract
We report the case of a 63-year-old woman with thiamine deficiency who showed auditory hallucinations, a delusion of persecution, catatonic stupor, and catalepsy but no neurological symptoms including oculomotor or gait disturbance. Brain MRI did not show high-intensity T2 signals in regions including the thalami, mamillary bodies, or periaqueductal area. Her thiamine concentration was 19 ng/mL, only slightly less than the reference range of 20-50 ng/mL. Her psychosis was unresponsive to antipsychotics or electroconvulsive therapy, but was ameliorated by repetitive intravenous thiamine administrations at 100-200 mg per day. However, one month after completing intravenous treatment, her psychosis recurred, even though she was given 150 mg of thiamine per day orally and her blood concentration of thiamine was maintained at far higher than the reference range. Again, intravenous thiamine administration was necessary to ameliorate her symptoms. The present patient indicates that the possibility of thiamine deficiency should be considered in cases of psychosis without neurological disturbance and high-intensity T2 MRI lesions. Also, this case suggests that a high blood thiamine concentration does not necessarily correspond to sufficient thiamine levels in the brain. Based on this, we must reconsider the importance of a high dose of thiamine administration as a therapy for thiamine deficiency. The validity of the reference range of the thiamine concentration, 20-50 ng/mL, is critically reviewed.

Abstract
The objectives of this study were to examine the effect of thiamine immersion of fish from a population known for compromised survival as a result of early mortality syndrome (EMS) and to investigate the cause-response relationship between thiamine concentration and lesions in tissues in swim-up-stage lake trout Salvelinus namaycush alevins. Lake trout eggs from 14 fish from Lake Michigan were artificially fertilized and the progeny divided into two groups based on the thiamine concentration (low [< 0.73 nmol/g] or high [> 0.85 nmol/g]) in the unfertilized eggs. Progeny were treated or not with a thiamine solution (2,000 mg/L for 2 h) at hatching or the swim-up stage. The survival of progeny in control groups at the swim-up stage correlated with thiamine concentration. The low thiamine-treated groups had significantly higher survival between the swim-up stage (812.0 degree-days) and 16 d after swim-up (963.3 degree-days) than the control groups; the survival of the high thiamine-treated groups did not differ between treated and control fish, regardless of the treatment at hatching and the swim-up stage. Control alevins that had low thiamine levels showed EMS, which resulted in 94.9-100% mortality 16 d after the swim-up stage. No pathological changes were observed in the brain, olfactory lobe, eye, liver, or muscle in alevins of high thiamine-treated group. Glycogen deposits in the liver of alevins from the low control group were variable, no glycogen being observed in the hepatocytes of 7 of the 24 fish. We demonstrate that thiamine treatment at swim-up enhances the survival of EMS-affected lake trout relative to treatment at hatching.

Abstract
A 52-year-old woman was admitted to the hospital because of appetite loss, unsteadiness, psychogenic symptoms, ataxia, and consciousness disturbance as a result of the ingestion of a diet restricted to only carbohydrates for a long term. Laboratory examination indicated the presence of pancytopenia with macrocytic anemia; further, decreased vitamin B1 and B12 levels were detected in her serum. Magnetic resonance imaging fluid attenuated inversion recovery (FLAIR), revealed high-signal intensity in the bilateral corpus striatum, third ventricle circumference, and cerebellar cortex. Thereafter, she received drip infusion that did not include vitamin B1 or B12 and subsequently suffered a cardiac arrest due to the aggravation of cardiac insufficiency; consequently, she was transferred to our hospital. Upon admission the patient was diagnosed to have obvious cardiomegaly with pleural effusion; further, a negative T-wave was obtained on the electrocardiogram. A diagnosis of beriberi heart disease was made because of thiamine deficiency. She was treated by thiamine administration, following which the cardiac symptoms improved immediately. Various neurological symptoms caused by encephalopathy, peripheral neuropathy and subacute combined spinal cord degeneration improved by treatment with thiamine and cyanocobalamine administration; however, some of these symptoms still remained. General awareness of the fact that neurological symptoms can be caused by vitamin deficiency is essential.
