Myths and realities about alcohol and smoking in chronic pancreatitis
1Division of Gastroenterology, Hepatology and Nutrition, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania, USA.
Purpose Of Review:
Alcohol and smoking play an important role in pancreatitis. The present review will address the myths and evidences about alcohol and smoking with pancreatitis to help improve the approach of healthcare professionals when managing of these patients.
Recent Findings:
There is a growing recognition that chronic pancreatitis is a multifactorial disease. Eliciting an accurate history of alcohol consumption and smoking from patients, and if necessary, family members, can help determine their contribution to the patient's disease. In the absence of a convincing history, physicians should be open to consideration of other etiologies. The amount and duration of alcohol consumption is the most important determinant in increasing pancreatitis risk. Alcohol sensitizes the pancreas to other insults or injury and promotes disease progression. Smoking is an independent risk factor or chronic pancreatitis and has synergistic pathogenic effects with alcohol. The natural history of chronic pancreatitis is highly variable. A patient with alcoholic pancreatitis can have symptoms, recurrences or exacerbations from disease-related complications or nonpancreatic causes. Novel strategies are needed to enable patients quit smoking.
Summary:
Obtaining accurate history, appropriate evaluation and management can help to achieve meaningful improvement in symptoms in patients with chronic pancreatitis. Abstinence from alcohol and smoking cessation, when applicable, should be recommended in all patients to prevent disease recurrences and progression.

01:24Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

The process of oxidation in a chemical reaction is observed in any of the three forms:
02:29Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.
02:31Protection of Alcohols
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...
01:38Preparation of Alcohols via Substitution Reactions
Alcohols can be synthesized from alkyl halides via nucleophilic substitution reactions. The highly polar carbon-halogen bond in the substrate makes halide a good leaving group. The hydroxide ion or water can act as a nucleophile to take the place of halide and form an alcohol. The substitution reactions occur via two different reaction pathways, SN1 or SN2, depending on the nature of carbon attached to the halide.
Primary alcohols are synthesized from primary alkyl halides, and the...
