History of Presenting Illness • History of abnormal feelings about the right leg since age 4. • Possibly related to a TV character with an amputation to cause an attraction to amputees? • Age 7-13 thoughts of leg less urgent • Denied any altered sensations, lack of coordination, inattention injuries or motor problems with the leg as a child
History of Presenting Illness • Age 13 - thoughts recurred and the urge to be rid of the limb became intense • Did not feel his right lower leg was part of him • Accidentally tripped down a drain, injuring the right leg in the exact place that he wanted amputation • Attempted to infect leg by rubbing dirt into the wound • Did not seek medical attention • Day-dreamed of leg falling off

Investigations • On magneto-encephalography, touching his right foot produced just primary and secondary somatosensory activation but no activity in the superior right parietal lobe. • Had caloric vestibular stimulation • Partial relief if mirror was placed such that it created illusion that leg was no longer there.

If you’re not good with blood and all things a bit yucky…… LOOK AWAY NOW
17/03/2008 • Blood cultures-gram negative rods in 4/4 bottles • Wound-heel pad gangrenous • Commenced on Gentamycin and Ceftazidine
Opinions Rehabilitation team (Dr Ross Hawthorne) • Extensive necrosis of heel pad, no benefit from trying to save the foot or Syme’s amputation. • Supported trans-tibial amputation at the level desired by the patient. • Burns team supported the medical indication for below knee amputation.
Opinions Vascular team • Agree with need for amputation, wait until necrotic area fully demarcates • Further positive cultures → gram positive cocci- staph and strep • Commenced on Vancomycin
19/03/2008 • Heel necrosis worse and malodorous • Right foot swollen and cellulitic up to mid shin • Cultures growing Staph aureus, Enterococcus and Pseudomonas • Commenced on Tazocin
20/03/2008 • Calf muscle perfusion scan - non viable right gastrocnemius muscle
21/03/2008 • Right trans tibial amputation • No post operative complications
Rehabilitation Phase • Developed Phantom limb pain • Treated with Doxepin by Pain team and patient educated about stump massage • Rigid removable dressing commenced for stump management • Progressed well and became independent with his LL and UL exercises and mobility with crutches.
Function at Discharge • Independent with self care • Independent stump care • Independent mobility with crutches • Home visit was conducted with OT • Little equipment required for safe discharge to Aunt’s house on 17/04/2008 • Prescription for interim prosthesis made prior to discharge.
Attitude Since Amputation • Feels a weight lifted of his chest • Wants to return to normal life and activities • Feels no longer belongs to the BIID group • States expectations have been met • Has found acceptance from family members by explaining BIID as neurological condition
Physiotherapy Progression • Was quick to progress to independent mobility with prosthesis unaided. • Was starting to learn to run, however attendance at outpatient physio has been unreliable. • Now is happy with current abilities and finds he can play with kids at the park etc.
Body Integrity Identity Disorder (BIID) • Apotemnophilia, or body integrity identity disorder (BIID), is characterized by a feeling of mismatch between the internal feeling of how one’s body should be and the physical reality of how it actually is.
Body Integrity Identity Disorder (BIID) • The desire for amputation of a healthy limb was first reported in 1785(cited in Johnston & Elliott, 2002) • Money et al (1977) used the term apotemnophilia (amputation love) to describe intense and intrusive thoughts to amputate a lower extremity. These thoughts were related to sexual fantasies and sexual arousal. Sex Res1977;13:115-25) • Description of this disorder was limited to a few case reports from 1977-2003
Body Integrity Identity Disorder (BIID) • Long standing desire to be an amputee • Rare, mainly men • Often arises around 4 – 5 yrs age • Often accompanied by sexual arousal but not necessarily primary motive • Can arise in women • Extremes….
BIID • Patients with this condition have an often overwhelming desire for an amputation of a specific limb at a specific level. • Such patients are not psychotic or delusional • Such patients show a left - sided preponderance for their desired amputation
Apotemnophilia and Munchausen’s Syndrome. • Munchausen's patient is obsessed with self inducing symptoms repetitively for the sake of being a patient where as an apotemnophile is supposedly satisfied with just one amputation • Apotemnophiles need only one medical intervention that leaves them with obvious stigma of disability which will permanently satisfy their need for love and attention.
Factitious Disability Disorder • Bruno 1997- divided this disorder into 3 subsets • Devotees • Pretenders • Wannabes
Devotees • Devotees are non disabled people who are sexually attracted to people with disabilities, typically those with mobility impairments and amputees
Pretenders • Pretenders are non-disabled people who live as if they have a disability. • Pretender paraplegics can confine themselves to their chairs full time and never walk. • The pretender amputee has more difficulty trying to be an amputee and feels frustrated and dissatisfied.
Wannabes • Wannabes are usually non-disabled individuals that want to become someone with a physical disability. • See themselves in bodies that are not fully functioning. • They have difficulty finding identity.
BIID • The first person to use the term BIID was US psychiatrist Associate Professor Michael First from Columbia University, who interviewed 52 ‘wannabes’ as part of a recent study.
The Results • 90% had education beyond high school • 65% were currently employed. • 27% had surgical or self inflicted amputation • 17% had major limb amputation and two thirds had used methods that put themselves at high risk
The Results • He found that 15% of wannabes identified sexual arousal as a reason for amputation, 63% wanted to be restored to their "true identity" and 37% said the limb "felt different". • Thirteen percent said the limb didn't feel like their own and six people had tried to perform their own amputation, including using a chainsaw. • 87% reported being sexually attracted to other amputees.
Desired Location for Amputation • 95% wanted an amputation of major limb • 92% wanted above knee amputation • 55% wanted left sided amputation • In 77% the site of desired amputation was fixed since it started in childhood.
The Results • Most felt the somatosensory perception of the limb did not differ from that of their other limbs. • 65% had onset prior to age 8; and 98% had onset by age 16 years. • Majority reported exposure to an amputee in childhood. • 44% of First’s subjects reported that their desire interfered with social functioning, occupational functioning, or leisure activities.
Co-morbid Psychopathology • Three quarters reported having had psychiatric condition sometime in their lives. • Most commonly depression, anxiety and somatoform disorder.
