Does necrobiosis lipoidica run in families?

As this is the first report of necrobiosis lipoidica being inherited, further studies will be required to confirm and explore this linkage, to elucidate more deeply the underlying pathophysiology, and to define the natural history of necrobiosis lipoidica.

Anonymous Patient Answer

What does pcs499 usually treat?

Most PCS499 treated PNS; the most common PNS/neurologic conditions were NVC with necrobiosis lipoidica and mononeuropathy / mononeuritis. The most common PNS/neurologic condition was sciatic neuropathies, and the second-most common was neuropathies which have a neuromuscular cause. There was no significant difference between the number of PNS/neurologic conditions and the number of types of PNS/neurologic conditions between the PCS499-treated and control groups, suggesting that PCS499-treated PNS is not an absolute contraindication of PCS499 administration.

Anonymous Patient Answer

Can necrobiosis lipoidica be cured?

Our first report suggests that a small fraction of patients show a spontaneous remission-like clinical remission. These cases appear to be characterized by a chronic inflammatory process. The histological picture of NCL may be a clue to the development of a better therapeutical strategy with a focus on an early clinical and radiologic estimation of NCL clinical progression.

What are common treatments for necrobiosis lipoidica?

A high prevalence of NLD was observed among women aged 40 - 59 years in Japan. Use of topical corticosteroids was the most commonly prescribed treatment in the majority of patients, followed by antihistamines and other over-the-counter drugs. The treatments used to treat NLD should be guided by medical professionals with a good understanding of the pathophysiology of NLD and its relationship to various somatic conditions.

How many people get necrobiosis lipoidica a year in the United States?

There [is an increase in necrobiosis lipoidica in the U.S] between 1988 and 2006. The increase is greatest among whites and men. The age groups with the highest incidence are [median ages > 55 and 70-79 years]. Men and men with higher body mass index, who are not overweight but not grossly obese, are more likely to be affected in the U.S. Compared with those affected in other countries, [North Americans are more likely to have it occur in the eyelids or eye socket]. All of these findings support previous reports and may explain why patients with systemic metabolic diseases are considered at higher risk for necrobiosis lipoidica onset compared with patients without systemic metabolic diseases.

Anonymous Patient Answer

What are the signs of necrobiosis lipoidica?

Although NLC was once thought to only occur in younger women, this disorder can still be seen in adult women. Patients with NLC present with a variety of painful lesions, and often seek treatment before the correct diagnosis is made. For this reason, clinical and biopsy-based information regarding NLC is important as the correct and timely diagnosis can lead to optimal management and better outcomes.

What is necrobiosis lipoidica?

Necrobiosis lipoidica is a rare cutaneous disorder characterized by a solitary or multiple nodular or papular lesions. It occurs in the skin, especially around the face, trunk, and proximal extremities. The lesions typically occur mainly in women after the age of 40 years, but it can occur in children.

Anonymous Patient Answer

What causes necrobiosis lipoidica?

Although the mechanism by which the pathoplastic granuloma forms is not fully understood, the pathologist and patient must be aware of the possible association between necrobiosis lipoidica and NCL because treatment of NCL includes therapy designed to treat cutaneous necrobiasis.

What is pcs499?

The current report identifies Pcs499 as a candidate oncotoxin. Pcs499 is a candidate allergen in atopic dermatitis and has been shown to induce in vitro cytotoxicity as well as increase cell proliferation. It is known that it is formed in response to the action of bacterial lipase. This, in turn, could explain its pathogenic role in chronic inflammatory diseases (e.g. inflammatory bowel disease, psoriasis). The role of the cytotoxicity and cell proliferation in Pcs499, has not been shown and requires further study. The effects of Pcs499 have not been investigated on animals, however it could be a candidate carcinogen in humans.

Anonymous Patient Answer

What are the common side effects of pcs499?

With the common and severe side effects, it's advised to do more research on the side effect of PCS499. And how to control the side effect is the most important point of doctors' attention. The research result shows that the patients who have used PCS499 with moderate dosage and moderate duration shows less side effect than that of other drugs and the side effect of PCS499 is controllable in a short term. Therefore, use of PCS499 is advisable for patients with serious disease or patients who need a long-term drug treatment for surgery.

Anonymous Patient Answer

Is pcs499 typically used in combination with any other treatments?

This exploratory study indicates that PCS-499 can be used in patients with necrobiosis lipoidica, either alone or in combination with other dermatological therapies for this condition.
