RESUMEN

BACKGROUND: Chronic alcoholism refers to the unpleasant symptoms directly resulting from excessive drinking. Increased alcohol metabolites and an unbalanced oxidative state are likely to blame for the reported effects under these circumstances. According to preclinical and clinical research, vitamin B12 can act on several organ systems with demonstrated neuroprotective, antioxidant, and glutamate modulating properties. OBJECTIVE: This research sought to examine the ameliorative effects of vitamin B12 (VtB12) in persistent alcohol (AlOH) exposed adult zebrafish with the help of following parameters like the anxiety related behavior test, Oxidative stress, and antioxidant assays, histological and immunofluorescence analysis. METHODS: Zebrafish pretreated with 0.40% AlOH (v/v) for 120 min (+AlOH) or not (-AlOH), were exposed for 6 h to home tank water (-VtB12) or to 59 µg-VtB12/kg-fish food (+VtB12) to analyze anxiety behavior in the geotaxis (novel tank) test as well as the oxidative brain damage in the adult zebrafish. RESULTS: Adult zebrafish exposed to chronic AlOH showed a decrease in the distance travelled, average and mobility speed, and increased the average frozen time, the explored area, and total no. of the site explored in the trapezoid tank. AlOH exposure also resulted in oxidative damage, enhanced lipid peroxidation, advanced oxidative protein products, decreased enzymatic and non-enzymatic antioxidant activities, and enhanced reactive oxygen species generation. Additionally, VtB12 supplementation improved neurogenesis, evident in increased Nissl cell numbers and NeuN expression in the brain. CONCLUSION: Chronic alcoholism may be effect on the brain cells as well as on the neuro-behavior of zebrafish. This research demonstrated that VtB12 shows promise as a neuroprotective agent against chronic alcoholism induced alterations in zebrafish's brain.

RESUMEN

OBJECTIVE: The aim of this article is to answer three relevant issues: i/What epileptic condition is referred to as subacute encephalopathy with seizures in alcoholics (SESA) syndrome; ii/ Why it can be important to distinguish SESA syndrome in clinical practice and iii/ What do we know about its pathophysiology. METHODS: We reviewed all cases published in the English language from the initial description of the syndrome to the present. All met the previously established criteria for SESA syndrome were included in our analysis. RESULTS: We found 34 patients diagnosed with SESA syndrome Fourteen (41.1%) out of 34 patients were over 60 years of age. In 12 (35.2 %), abstinence, and in 4 (11.7 %) excessive consumption of alcohol, were considered precipitating factors, respectively. Triggering causes were unknown in 18 cases (53.0 %). All cases (100 %) presented with altered mental status. Fourteen (41.1 %) subjects had a history of epileptic seizures in the context of alcohol withdrawal syndrome (AWS). Twenty (58.8 %) patients had focal motor seizures (FMSs), 24 (70.5 %) bilateral tonic-clonic seizures (BTCSs), and 15 (44.1 %) focal impaired awareness seizures (FIASs). In 8 (23.5 %), criteria for focal nonconvulsive status epilepticus (NCSE) were met. Twenty-eight (82.3 %) subjects had transient neurological deficits. In 29 (85.2 %) subjects, lateralized periodic discharges (LPDs) were observed on the EEG. Areas of signal hyperintensities and restricted diffusion in neuroimaging were mentioned in 22 subjects (64.7 %). Transfer to the intensive care unit was necessary in 8 (23.5 %) subjects. Thirteen (38.2 %) had recurrent episodes. Enduring brain damage was mentioned in 9 (26.4 %) cases. The most used anti-seizure medication (ASM) was levetiracetam, followed by phenytoin and lacosamide. CONCLUSIONS: SESA syndrome represents a well-defined subtype of focal NCSE in patients with chronic alcoholism. Its prompt recognition can facilitate the initiation of early ASM therapy and help design appropriate video-EEG evaluation and a treatment strategy.

RESUMEN

PURPOSE: To describe four patients with subacute encephalopathy with seizures in alcoholics (SESA) syndrome and to review its clinical, electroencephalogram (EEG), neuroimaging and diagnostic criteria. METHODS: We conducted a retrospective analysis of a series of prospectively collected patients who met the previously established criteria for SESA syndrome. Subsequently, we reviewed all cases published in the English language from the initial description to the present. RESULTS: We found 34 patients diagnosed with SESA syndrome to date, including the four cases of SESA in this report. Fourteen out of 34 (41.1 %) patients were over 60 years of age. Twelve (35.2 %) were abstinent from alcohol and in 4 (11.7 %) there was excessive alcohol consumption. Triggering causes were unknown in 18 cases (53.0 %). All cases (100 %) presented with an altered mental status. Fourteen (41.1 %) subjects had a history of epileptic seizures in the context of acute withdrawal syndrome (AWS). Twenty (58.8 %) patients had focal motor seizures (FMSs), 24 (70.5 %) bilateral tonic-clonic seizures (BTCSs), and 15 (44.1 %) focal impaired awareness seizures (FIASs). In 8 (23.5 %), criteria for focal nonconvulsive status epilepticus (NCSE) were met. Twenty-eight (82.3 %) subjects had transient neurological deficits. In 29 (85.2 %) subjects, lateralized periodic discharges (LPDs) were observed in the EEG. Areas of increased T2/FLAIR signal and restricted diffusion were mentioned in 22 subjects (64.7 %). Transfer to the intensive care unit (ICU) was necessary in 8 (23.5 %) subjects. Thirteen (38.2 %) had recurrent episodes. Enduring cerebral sequelae had been mentioned in 9 (26.4 %) cases. The most used anti-seizure medication (ASM) was levetiracetam, followed by phenytoin and lacosamide. CONCLUSION: SESA syndrome represents a well-defined subtype of focal NCSE in patients with chronic alcoholism. Its prompt recognition can facilitate the initiation of early ASM therapy and help implement a video-EEG evaluation and neuroimaging strategy.

RESUMEN

Long-standing overt ventriculomegaly in adults (LOVA) is a kind of chronic hydrocephalus that has been reported to have started in infancy and is characterized by severe ventriculomegaly and macrocephaly. It often manifests clinically in later adulthood. We describe the case of a 34-year-old male patient who had a history of chronic alcoholism and who had been complaining of headaches, disturbed gait, and frequent falls for three months when he arrived in a stupor at the emergency room. Massive ventriculomegaly with Evans' index of 0.40 was found during a head magnetic resonance imaging (MRI). The MRI results were more severe than the clinical manifestations. He was diagnosed with LOVA and treated with conservative hyperosmolar drugs, neuroprotective agents, and intravenous (IV) thiamine. The patient was discharged and consented to follow-up after a hospital stay of seven days.

RESUMEN

Alcohol has always been a component in the dietary pattern of human civilization. It is widely used in society for celebration and socialization. Alcohol abuse is among the most serious problems in public health characterized by uncontrolled drinking which causes physical and emotional dependence on alcohol. Chronic alcoholics are at a higher risk of developing vitamin B1 deficiency due to malabsorption, poor diet, and an increased demand for nutrition. Vitamin B1(Thiamine) is an essential nutrient required for the body's energy metabolism and proper functioning of the nervous system. A person who excessively consumes madya (alcohol) and then abruptly discontinues drinking and takes recourse to drinking excess madya once again, suffers from Madatyaya Upadrava(chronic alcoholism) that is Vikshay. Here is a case report of an alcoholic patient who ceased drinking and then resumed alcohol in large amounts. He presented with symptoms of generalized weakness, body ache, aphasia, confusion, fever (on and off), thirst, cough, headache, and numbness. The patient underwent a two-month treatment regimen that combined Satvavajay Chikitsa, Yoga, and Shaman Chikitsa involving Rasayana medications and procedures including snehan (Oleation), swedan (fomentation), nabhi puran (filling oil with navel), nasya (nasal administration), shirodhara (continuous flow of liquid on head) and basti (medicated enema). The intervention outcome showed relief from the aforementioned symptoms and improvement in both symptoms and GCS(Glasgow coma scale) score. This treatment approach aimed to promote vitality, longevity, and an overall sense of balance and well-being. There are not many corroborating cases being reported and managed with Ayurveda. This case report highlights transforming health through the cumulative effects of Rasayana medicines, panchakarma, and yoga.

RESUMEN

Zieve's syndrome, associated with chronic alcoholism, manifests as hemolytic anemia, transient hyperlipidemia, and cholestatic jaundice. Key symptoms comprise nausea, abdominal pain, and jaundice. Diagnosis relies on recognizing the triad in those with an alcohol use history. Supportive management includes blood transfusions and alcohol cessation. The exact pathophysiology remains uncertain, with hypotheses ranging from alcohol-induced liver damage to autoimmune processes. The report emphasizes diagnostic complexities, particularly when concurrent with autoimmune disorders such as latent autoimmune diabetes of adults or complicated by disseminated intravascular coagulation (DIC). A 36-year-old male with latent autoimmune diabetes of adults and an 18-year history of chronic alcoholism presented with yellowish skin discoloration, abdominal pain, and distension. Physical examination revealed signs of anemia, jaundice, pedal edema, hepatomegaly, splenomegaly, and abdominal tenderness. Over eight admissions, multiple tests revealed severe anemia, thrombocytopenia, elevated bilirubin, and positive autoantibodies. Treatment for suspected autoimmune hepatitis showed no improvement. Subsequent examinations indicated DIC, altered liver function, and cirrhosis progression. A confirmed diagnosis of Zieve's syndrome was made. Upper gastrointestinal endoscopy was done to check for esophageal varices which were banded. The patient was subsequently managed on supportive treatment with multiple blood transfusions and abstinence from alcohol. Prompt recognition of Zieve's syndrome is crucial to avoid unnecessary interventions. Alcohol cessation is the keystone of treatment, emphasizing the need to raise awareness among practitioners. This case points toward the importance of comprehensive evaluation, serial investigations, and multidisciplinary collaboration for accurate diagnosis and management. Further research is needed to enhance understanding and optimize therapeutic strategies.

RESUMEN

This case report documents a rare occurrence of pellagra in a chronic alcoholic individual, characterized by a pruritic rash and gastrointestinal symptoms. The patient, a Caucasian male in his 60s, with a history of alcohol use disorder, presented with worsening skin lesions and non-bloody diarrhea. Laboratory findings revealed significant deficiencies in niacin and related metabolites, confirming the diagnosis. Prompt initiation of niacin supplementation, dietary adjustments, and supportive care led to notable improvements. This case shows the critical importance of recognizing pellagra in chronic alcoholism, emphasizing the triad of symptoms - rash, diarrhea, and malnutrition - as key diagnostic markers. Early intervention holds the potential to significantly enhance the patient's well-being and prevent disease progression.

RESUMEN

Pyridoxine deficiency is a prevalent condition in the United States that primarily affects patients with alcohol use disorder. The presentation of this condition is very nonspecific and commonly presents with a constellation of symptoms including peripheral neuropathy, stomatitis, dermatitis, confusion, depression, encephalopathy, and seizures. Over half of these patients have associated alcohol use disorder, which causes pyridoxine deficiency due to the breakdown of pyridoxal phosphate during ethanol metabolism in the liver. As an important cofactor in the synthesis of γ-aminobutyric acid (GABA), deficient levels of pyridoxine may lower the seizure threshold due to reduced GABA-mediated inhibition. This case details a 57-year-old male with chronic alcoholism and a history of seizures who developed episodes of myoclonic jerks, tremors, anxiety, and neuropathy whose symptoms persisted even while on anti-epileptic medication. He was found to have pyridoxine deficiency and had full resolution of symptoms shortly after the administration of vitamin B6 supplementation. Pyridoxine deficiency may lead to severe neurologic disorders such as encephalopathy and seizures. Hence, it is important to consider pyridoxine deficiency in the workup of neurologic complaints, especially in high-risk patients.

RESUMEN

Alcohol has been widely consumed for centuries and is linked to the aggravation of diseases. Several studies have shown that excessive consumption of ethanol results in morphophysiological changes in the male reproductive system. One of the effects of ethanol is the decrease in testosterone concentration and hormonal therapies are an alternative to minimize the changes resulting from chronic alcoholism. Qualitative studies were commonly carried out to evaluate the male histopathological alterations resulting from ethanol consumption, being necessary quantitative and non-subjective techniques. This study analyzes the importance of fractal analysis as a useful tool to identify and quantify tissue remodeling in rats submitted to ethanol consumption and hormone therapy with testosterone. Prostate of animals submitted to chronic ethanol consumption showed tissue disorganization, which was confirmed by an increasing of fractal dimension. Regarding the prostatic stroma, collagen fractal dimension and quantification revealed lower values in animals that were only submitted to androgen therapy. Thus, we can conclude that the fractal analysis was a useful tool to quantify tissue changes caused by ethanol consumption and androgen therapy.

RESUMEN

Chronic pancreatitis has been shown to cause various pathologies, such as biliary strictures and pancreatic malignancies, which can in turn result in biliary outlet obstruction. However, a pancreatic calculus itself resulting in biliary obstruction has been far less observed. The patient in question had a documented history of chronic alcoholism and received a cholecystectomy decades prior to the onset of cholestatic symptoms. Cholangiography demonstrated no indication of biliary stricture formation, nor was there radiological evidence of pancreatic pseudocyst or malignant formation. CT evidence across a decade of time established a storyline of pancreatic calculi formation, migration, and resultant biliary obstruction. Subsequent endoscopic sphincterectomy, pancreatic calculi removal, and biliary tree stent placement resulted in laboratory value normalization and clinical symptom resolution.

RESUMEN

In this case study, a 73-year-old man who had previously undergone colectomy had a history of ulcerative colitis and alcohol abuse and presented with fatigue, weight loss, and a liver lesion. After a biopsy, he was diagnosed with stage IV-A hepatocellular carcinoma with poor differentiation and cirrhotic architecture, and molecular testing revealed positivity for multiple genes. A combination of atezolizumab and bevacizumab was administered, resulting in complete remission lasting beyond 16 months, demonstrating the potential of these drugs as a treatment option for advanced hepatocellular carcinoma (HCC). The patient's history of autoimmune conditions could have contributed to his robust response to the treatment. The report highlights the sustained survival benefits of this treatment beyond month 16.

RESUMEN

Marchiafava-Bignami disease (MBD) is rare and often associated with chronic alcohol consumption; however, cases have been described in non-alcoholic patients with nutritional deficits. This disease manifests itself through an array of neurological signs and symptoms, from mild dysarthria or mild confusion to coma and death, and can present acutely, subacutely, or chronically, depending on their severity. The evolution of imaging technology makes magnetic resonance imaging (MRI) the gold standard for the diagnosis of this disease, although computed tomography (CT) scan is usually in the first line owing to its greater availability. The main feature for the diagnosis of MBD by brain MRI is the identification of areas of demyelination and necrosis of the corpus callosum. We report a 55-year-old male with subacute neurological deterioration whose MRI demonstrated atrophy and demyelination of the corpus callosum.

RESUMEN

The most common cutaneous manifestations of alcoholism include urticarial reaction, flushing, porphyria cutanea tarda, psoriasis, rosacea, seborrheic dermatitis, and pruritus. Here, we present a case of a young male with a history of alcohol abuse who presented with non-blanching, petechial, and perifollicular macular rash secondary to vitamin C deficiency in view of poor oral intake. The rash improved significantly with vitamin C supplementation. Although rare in developed countries, clinicians should keep vitamin C deficiency as a differential diagnosis for skin rash in alcohol consumers.

RESUMEN

Pleural effusion is the accumulation of extra fluid between the layers of the pleura outside the lungs, also known as water on the lungs. Pleura are thin membranes that lubricate and aid breathing by lining the lungs and the inside of the chest cavity. The pleural space typically contains only a few teaspoons of watery fluid, which enables the lungs to move easily inside the chest cavity when breathing. Several barriers limited the patient's capacity to carry out daily activities successfully and efficiently. Loculated effusions are most frequently associated with diseases such as empyema, hemothorax, or tuberculosis that result in severe pleural inflammation. Hence, a physiotherapy program is started to help improve the patient's symptoms. A 59-year-old male presented to the hospital with the chief complaint of left-sided chest pain, fever, and breathlessness. On the Modified Medical Research Council dyspnea scale, breathlessness was grade 3.

RESUMEN

Fanconi syndrome is described as a defect in the proximal tubular reabsorption of glucose, amino acids, uric acid, phosphate, and bicarbonate, falling under type 2 renal tubular acidosis (RTA). Some common causes include drugs, heavy metals, infections, and genetics (particularly mitochondrial disorders).  We present a case of a 33-year-old Caucasian female with chronic alcohol use disorder. She was treated for acute kidney injury (AKI) but had persistent hypophosphatemia, hypokalemia, hypouricemia, low bicarbonate, along with glycosuria consistent with Fanconi syndrome. An exhaustive workup ruled out the most common causes. Alcohol abstinence proved to correct the underlying abnormality.  Alcohol is a mitochondrial toxin, and its role in the pathophysiology of Fanconi syndrome is under investigation. Early diagnosis of Fanconi is imperative to avoid complications such as rickets and osteomalacia. Therefore, testing for markers of alcohol abuse should be considered when determining the etiology of Fanconi syndrome.  Alcohol use disorder is a common disorder, with more than 3 million cases annually in the US alone. Clinicians should have a high index of suspicion for Fanconi syndrome in a patient with similar anomalous labs considering the high prevalence of alcohol use disorder. More research regarding this topic is warranted.

RESUMEN

Introduction: Central pontine myelinolysis is a type of osmotic demyelination syndrome, which involves damage to parts of brain most commonly pons. The most common causes include rapid correction of hyponatremia but other precipitating factors including alcoholism, diabetes, and chronic liver disease should also be considered. Case presentation: We present a case of 44-year-old male with a history of chronic alcohol consumption, who presented in emergency room with complaints of slurring of speech and weakness of both upper and lower limbs. His MRI brain reveals 'trident-shaped' appearance with findings of High T2W/FLAIR signal noted in the pons with relative sparing of the periphery and hypo intense on T1W images. He was managed conservatively. Clinical discussion: Proper diagnosis with MRI is needed for early detection so that proper intervention can be made on time. Conclusion: CPM can occur in the patient even if they are normonatremic or hyponatremic but can precipitate in Chronic Alcoholic patients.

RESUMEN

Suicide is a phenomenon that is not related to a specific class of countries but is a problem worldwide. Many studies have attempted to explain gender differences in suicidal behaviors. Unfortunately, Russia holds the world's top place for the number of suicides committed by its male citizens. Russia is still demonstrating unusually high death rates due to non-natural causes, and these demographic trends are concerning. We analyzed suicidality among men in Russia over the past 20 years using official data published by the Federal State Statistics Service (Rosstat) and secondary sources. We also discussed male suicide as a social problem, analyzed, and evaluated male suicidality in Russia from 2000 to 2020, and reviewed the factors influencing the prevalence of male suicides over female suicides in Russia. Russia is still going through one of the most significant historical changes in the last 100 years. Our analysis showed discrepancies between official numbers and data published by non-government organizations in Russia. Unemployment, low socioeconomic status, underdiagnosed and/or untreated mental illness, and substance abuse are major risk factors for suicide in Russian men. Cultural influences also make suicidal behavior socially scripted in Russia. By providing examples and analyzing data, we aspire to encourage improvements in the practice of mental wellbeing in Russia and other post-Soviet countries. The recommendations within this report are intended as a starting point for dialogue to guide effective suicide prevention in this country.

RESUMEN

Objective: Cirrhosis is common in Ghana because of its high risk factors prevalence. However, information on cirrhosis in Ghana is lacking. This study aimed to study the clinical, and laboratory characteristics of cirrhotic patients in a tertiary hospital in Ghana. Design: This was a retrospective study of sociodemographic characteristics, symptoms and signs, biochemical and fibrotic indices, treatments, and complications data of 247 patients with cirrhosis who died on admission. Setting: This study was carried out at the Gastroenterology Unit of the Korle-Bu Teaching Hospital, Ghana. Results: Two-thirds (68.0%) of the patients were within 30 to 60 years, with more than half (73.7%) being males. The most common aetiological factors among the patients were Hepatitis B virus infection (53.8%), alcohol use (31.6%) and Hepatitis C virus infection (4.9%). More than half (55.0%) of the patients reported late for admission, and 67.2% died within the first two weeks of admission. The most common clinical feature was abdominal distension (61.1% of patients), and the least was upper-abdominal mass (14.2%). The levels of most liver test parameters were elevated, fibrotic indices were high, and haemoglobin and albumin levels were reduced. More than half (53.8%) of the patients were in Child Pugh class B. The most common complication was hepatic encephalopathy; the least was hepato-renal syndrome. Definite treatment for complications of cirrhosis was lacking. Conclusion: Deaths from cirrhosis at the hospital were mostly of young males with chronic hepatitis B infection. Implementation of hepatitis B prevention and treatment guidelines can help reduce cirrhosis deaths. Funding: None declared.

RESUMEN

ObjectiveMetabolomics was used to identify biomarkers of chronic alcoholism, and to evaluate the neuroprotective effect of geniposide, providing reference for the diagnosis and treatment of chronic alcoholism. MethodThe rat model of chronic alcoholism was established by intragastric administration of 50% ethanol with 8 mL·kg-1 for 14 days, and then increased to 12 mL·kg-1 for 21 days. Meanwhile, the intervention was performed by continuous gavage of geniposide (15 mg·kg-1) for 35 days. At the end of the experiment, the biochemical indexes and histopathological morphology of liver and brain tissues of rats were detected. Ultra performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MS) was used for urine metabonomics. The chromatographic conditions was as follows:ACQUITY UPLC™ HSS T3 column (2.1 mm×100 mm, 1.8 μm), mobile phase of 0.1% formic acid acetonitrile solution (A)-0.1% formic acid aqueous solution (B) for gradient elution (0-2.5 min, 1%-11%A; 2.5-4.5 min, 11%-21%A; 4.5-7.0 min, 21%-40%A; 7.0-8.5 min, 40%-99%A; 8.5-10.5 min, 99%A; 10.5-10.6 min, 99%-1%A; 10.6-13.0 min, 1%A), the flow rate of 0.4 mL·min-1. The conditions of mass spectrometry were electrospray ionization (ESI), positive and negative ion modes, scanning range of m/z 50-1 200. Progenesis QI 2.0 and MassLynx 4.1 were used for data analysis, and biomarkers were identified by matching element composition and secondary fragments with Human Metabolome Database (HMDB). ResultThe pathological results showed that on the 35th day of model replication, compared with the model group, the cortical neurons in the geniposide group showed a significantly improved state of disorder, nuclear pyknosis, hyperchromatism and cell membrane boundary blurred necrosis. The biochemical results showed that geniposide could significantly increase the activities of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD), decrease the activity of acetylcholinesterase (AChE), decrease the levels of β-endorphin (β-EP) and malondialdehyde (MDA). A total of 48 biomarkers of chronic alcoholism were identified by metabonomics, involving seven metabolic pathways of tryptophan metabolism, phenylalanine metabolism, pentose and glucuronate interconversions, pyrimidine metabolism, ascorbate and aldarate metabolism, steroid hormone biosynthesis and purine metabolism. The main pathway is 5-hydroxytryptamine pathway of tryptophan metabolism. ConclusionBiomarkers related to nerve injury in chronic alcoholism are mainly derived from the 5-hydroxytryptamine metabolic pathway. Geniposide can regulate this pathway so as to improve oxidative stress in the brain and play a neuroprotective role.

RESUMEN

Molecular specific photonics localization method, the inverse participation ratio (IPR) technique, is a powerful procedure to probe the nano- to submicron scales structural alterations in cells/tissues in their abnormalities due to chronic alcoholism using confocal imaging. Chronic alcoholism introduces abnormalities in brain cells/tissue at the nanoscale level that results in behavioural and psychological disorders which are not well understood. On the other hand, probiotics such as Lactobacillus plantarum enhances brain functions in chronic alcoholism. Using the IPR technique, we probe the molecular specific spatial structural alterations in glial brain cells astrocytes and microglia, as well as in chromatins in the nuclei of cortex brain cells, with or without probiotic treatments in chronic alcoholism. The results show chronic alcoholism alone harms brain cells and the probiotic treatment in chronic alcoholism reverses alcoholic damage in the brain cells/tissues toward normalcy.
