Therefore, in the case "The Secretary, Department of Family and Community Services and the Harper Children [2016] NSWChC 3", the expert testimony of Professor David Isaacs that a certain blood test result was "highly unlikely" to occur naturally or accidentally (without any speculation about motive), was sufficient to refuse the return of the affected child and his younger siblings to the mother. The children had initially been removed from the mothers custody after the blood test results became known. The fact that the affected child quickly improved both medically and behaviourly after being removed was also a factor. Notable cases
Beverley Allitt, a British nurse who murdered four children and injured a further nine in 1991 at Grantham and Kesteven Hospital, Lincolnshire, was diagnosed with Munchausen syndrome by proxy.Wendi Michelle Scott is a Frederick, Maryland, mother who was charged with sickening her four-year-old daughter.The book Sickened, by Julie Gregory, details her life growing up with a mother who had Munchausen by proxy, who took her to various doctors, coached her to act sicker than she was and to exaggerate her symptoms, and who demanded increasingly invasive procedures to diagnose Gregorys enforced imaginary illnesses.Lisa Hayden-Johnson of Devon was jailed for three years and three months after subjecting her son to a total of 325 medical actions – including being forced to use a wheelchair and being fed through a tube in his stomach.
Another characteristic of the allergic contact dermatitis rash is that it usually appears after a day or two after exposure to the allergen, unlike irritant contact dermatitis that appears immediately after the contact with the trigger. Other symptoms may include itching, skin redness or inflammation, localized swelling and the area may become more tender or warmer. If left untreated, the skin may darken and become leathery and cracked. Pain can also be present. Dermatitis can occur anywhere on the skin, but is most common on the hands (22% of people), scattered across the body (18%), or on the face (17%).The rash and other symptoms typically occur 24 to 48 hours after the exposure; in some cases, the rash may persist for weeks. Once an individual has developed a skin reaction to a certain substance it is most likely that they will have it for the rest of their life, and the symptoms will reappear when in contact with the allergen. Cause
Common allergens implicated include the following: 

Bacitracin – topical antibiotic found by itself, or as Polysporin or Triple Antibiotic
Balsam of Peru (Myroxylon pereirae) – used in food and drink for flavoring, in perfumes and toiletries for fragrance, and in medicine and pharmaceutical items for healing properties; derived from tree resin. It may also be a component of artificial vanilla and/or cinnamon flavorings. Chromium – used in the tanning of leather. Also a component of uncured cement/mortar, facial cosmetics and some bar soaps.
