In severe cases of thiamine deficiency, a few of the positive symptoms (including neuropathic pain) may persist indefinitely. Even after the restoration of a balanced nutritional intake, those patients with severe or chronic polyneuropathy may experience lifelong residual symptoms. Epidemiology
In 2020 the NIH quoted an estimate that in the United States 25% to 66% of chronic alcohol users experience some form of neuropathy. The rate of incidence of alcoholic polyneuropathy involving sensory and motor polyneuropathy has been stated as from 10% to 50% of alcoholics depending on the subject selection and diagnostic criteria. If electrodiagnostic criteria are used, alcoholic polyneuropathy may be found in up to 90% of individuals being assessed.The distribution and severity of the disease depends on regional dietary habits, individual drinking habits, as well as an individuals genetics. Large studies have been conducted and show that alcoholic polyneuropathy severity and incidence correlates best with the total lifetime consumption of alcohol. Factors such as nutritional intake, age, or other medical conditions are correlate in lesser degrees. For unknown reasons, alcoholic polyneuropathy has a high incidence in women.Certain alcoholic beverages can also contain congeners that may also be bioactive; therefore, the consumption of varying alcohol beverages may result in different health consequences. An individuals nutritional intake also plays a role in the development of this disease.
CHP is a rare and often fatal form of panniculitis with multisystem involvement. But it can also present in a benign form involving only the subcutaneous tissue, thus having a broad clinical spectrum. Traumatic panniculitis is a panniculitis that occurs following trauma to the skin. : 492

Lipodermatosclerosis is a form of panniculitis associated with chronic venous insufficiency that presents with brown indurations on the front of the shins. It may be associated with pain and other signs of chronic venous insufficiency. The exact cause is unknown.Other forms include:

Subcutaneous fat necrosis of the newborn, a form of panniculitis occurring in newborns that is usually self-resolving, that may be a result of hypoxic injury to relatively high levels of brown fat.
