Review
Disorders of esophageal motility have been described in patients with cirrhosis in a small number of studies. In this review, we aim to provide an overview of the available evidence on esophageal motility disorders in cirrhosis and their clinical implications. This review delves into the following concepts: (1) Gastroesophageal reflux disease is common in liver cirrhosis due to many mechanisms; however, when symptomatic it is usually nocturnal and has an atypical presentation; (2) Endoscopic band ligation is better than sclerotherapy in terms of its effect on esophageal motility and seems to correct dysmotilities resulting from the mechanical effect of esophageal varices; (3) Chronic alcoholism has no major effects on esophageal motility activity other than lower esophageal sphincter hypertension among those with alcoholic autonomic neuropathy; (4) An association between primary biliary cholangitis and scleroderma can be present and esophageal hypomotility is not uncommon in this scenario; and (5) Cyclosporin-based immunosuppression in liver transplant patients can have a neurotoxic effect on the esophageal myenteric plexus leading to reversible achalasia-like manifestations.

Tobacco and alcohol dependence are known to cause choroidal neovascularization and toxic optic neuropathy, although these typically occur in isolation. In this case report, we describe a 54-year-old male who presented with a juxtafoveal choroidal neovascular membrane (CNVM) in the left eye. Over the course of the next two years, his vision worsened significantly in both eyes, and he developed decreased color vision and paracentral scotomas. Impaired photoreceptor response was detected on full-field electroretinography in both eyes. MRI of the brain and orbits was normal, and laboratory tests for optic neuropathy were within normal limits, except for highly elevated cotinine and nicotine levels. He was in the habit of chewing tobacco nearly constantly, and he admitted to drinking 15-20 alcoholic beverages per week. He was diagnosed with choroidal neovascularization and optic atrophy due to tobacco and alcohol overuse. The effects of tobacco and alcohol use on the health of the choroidal vasculature and optic nerve are discussed in the article.

BACKGROUND
the autonomic dysfunction defines the neuropathy of the autonomic nervous system. The prevalence of the gastric dysmotility and its relationship with the autonomic dysfunction in patients with alcohol chronic liver disease is not well known.
METHODS
thirty-six patients with alcohol chronic liver disease and 25 healthy controls were evaluated, in order to detect an autonomic dysfunction through different cardiovascular reflexes and gastric emptying tests.
RESULTS
ninety-four per cent of the patients showed an impaired R index (variations in heart rate during six deep inspirations-expirations per minute) and/or S/S-HR (variations in heart rate when standing from a supine position). Seventy-five per cent of the patients showed gastroparesis (T1/2: gastric half-emptying time was delayed). There was a correlation between the R index and T1/2 (r = -0.49; p < 0.01).
CONCLUSIONS
we suggest that gastroparesis detected in alcoholic chronic liver disease is another clinical manifestation of the autonomic parasympathetic dysfunction.

BACKGROUND
Pseudo-ainhum is defined as any case of auto-amputation not associated with the classic spontaneous ainhum seen in Africans with unknown etiology.
CASE PRESENTATION
A severely ill 58-year-old male patient presented with a painless constricting circular band on his left second toe. His medical history was remarkable for severe alcoholic liver cirrhosis with ascites formation leading to dyspnea. He had a hypoalbuminemia and a pronounced peripheral sensory neuropathy.
CONCLUSION
Here we present the second case of pseudo-ainhum associated with liver cirrhosis.

INTRODUCTION
Non-alcoholic fatty liver disease (NAFLD) is associated with an increased risk of complications in type 1 diabetes (T1DM) patients. To date, several biochemical indexes of NAFLD have been developed. Among these, hepatic steatosis index (HSI) strongly relates with the results of magnetic resonance.
AIM
The aim of the present study was to evaluate the possible association between HSI and complications in T1DM.
METHODS
Medical records of patients with T1DM were evaluated. Macro- and micro-vascular complications were evaluated by a combination of instrumental (ECG, carotid artery echo-Doppler, fundus examination, vibration threshold at biothesiometry) and laboratory examination. HSI was calculated based on gender, body mass index and transaminases level.
RESULTS
Of the 124 patients evaluated, 71 were free of complications and 53 had at least one complication. The prevalence of diabetes complications was: 27% for retinopathy, 15% for carotid atherosclerosis, 16% for neuropathy. HSI was directly correlated with age, disease duration, triglycerides, total daily insulin and inversely with HDL and eGFR. In logistic regression analysis, HSI was independently associated with diabetic complications.
CONCLUSION
These findings show that HSI is independently associated with the presence of complications in subjects with T1DM. This can be of clinical utility, allowing a better diagnostic classification of the patient and possibly guiding the therapeutic choice.

Excessive alcohol consumption is associated with spontaneous burning pain, hyperalgesia, and allodynia. Although acetaldehyde has been implicated in the painful alcoholic neuropathy, the mechanism by which the ethanol metabolite causes pain symptoms is unknown. Acute ethanol ingestion caused delayed mechanical allodynia in mice. Inhibition of alcohol dehydrogenase (ADH) or deletion of transient receptor potential ankyrin 1 (TRPA1), a sensor for oxidative and carbonyl stress, prevented allodynia. Acetaldehyde generated by ADH in both liver and Schwann cells surrounding nociceptors was required for TRPA1-induced mechanical allodynia. Plp1-Cre Trpa1fl/fl mice with a tamoxifen-inducible specific deletion of TRPA1 in Schwann cells revealed that channel activation by acetaldehyde in these cells initiates a NADPH oxidase-1-dependent (NOX1-dependent) production of hydrogen peroxide (H2O2) and 4-hydroxynonenal (4-HNE), which sustains allodynia by paracrine targeting of nociceptor TRPA1. Chronic ethanol ingestion caused prolonged mechanical allodynia and loss of intraepidermal small nerve fibers in WT mice. While Trpa1-/- or Plp1-Cre Trpa1fl/fl mice did not develop mechanical allodynia, they did not show any protection from the small-fiber neuropathy. Human Schwann cells express ADH/TRPA1/NOX1 and recapitulate the proalgesic functions of mouse Schwann cells. TRPA1 antagonists might attenuate some symptoms of alcohol-related pain.

Meta-Analysis
The primary aim of this systematic review was to establish the prevalence, character, and risk factors of peripheral neuropathy amongst chronic alcohol abusers and to identify the most appropriate management strategies. In this review, possible pathogenetic mechanisms are also discussed. A systematic, computer-based search was conducted using the PubMed database. Data regarding the above parameters were extracted. 87 articles were included in this review, 29 case-control studies, 52 prospective/retrospective cohort studies and 2 randomised control trials, 1 cross sectional study, and 3 population-based studies. The prevalence of peripheral neuropathy amongst chronic alcohol abusers is 46.3% (CI 35.7- 57.3%) when confirmed via nerve conduction studies. Alcohol-related peripheral neuropathy generally presents as a progressive, predominantly sensory axonal length-dependent neuropathy. The most important risk factor for alcohol-related peripheral neuropathy is the total lifetime dose of ethanol, although other risk factors have been identified including genetic, male gender, and type of alcohol consumed. At present, it is unclear what the pathogenetic mechanisms for the development of neuropathy amongst those who chronically abuse alcohol are, and therefore, it is unknown whether it is attributed to the direct toxic effects of ethanol or another currently unidentified factor. There is presently sparse data to support a particular management strategy in alcohol-related peripheral neuropathy, but the limited data available appears to support the use of vitamin supplementation, particularly of B-vitamin regimens inclusive of thiamine.
