Case Reports
[Mirror therapy for the treatment of phantom limb pain after bilateral thigh amputation : A case report.]
This case study is the first to report successful treatment of bilateral phantom limb pain (PLP) in a patient with bilateral thigh amputation and inefficacious medical treatment using a protocol of graded interventions including mirror therapy (MT). MT is a common treatment for PLP but requires the induction of a visual illusion of an intact limb in the mirror, usually achieved by mirroring the healthy extremity. Here, we illustrate how application of a unilateral prosthesis sufficed to induce the necessary illusion. ⋯ Pain intensity was reduced by more than 85 %; the number of attacks were decreased by more than 90% per day. The analgesic efficacy lasted until the unexpected death of the patient several months later. This case illustrates the mechanisms of MT through overcoming the sensory incongruences underlying the distorted body schema and its efficacy in patients with bilateral amputation.

The aim of the study was to compare the opioid piritramide (7.5 mg/ml) which is commonly used in Germany (equipotential 5 mg morphine) to oxycodone (10 mg/ml) when given for patient-controlled intravenous analgesia (PCIA) in surgical disciplines, such as general surgery, orthopedic surgery, trauma surgery and gynecological surgery. Typical side effects of the respective opioids and safety of the procedures were compared. Oxycodone is available both as parenteral and oral formulations. ⋯ The direct comparison of piritramide and oxycodone showed advantages for oxycodone in terms of typical opioid side effects. The effectiveness of analgesia was comparable in both groups.

Quantitative sensory testing (QST) is a standardized and formalized set of clinical sensitivity tests based on subjective (psychophysical) methods, which depends on the cooperation of the subject being investigated. Calibrated stimuli are used to measure the perception and pain thresholds, which provide information on the presence of sensory plus or minus signs. The QST equipment presented mimics natural thermal or mechanical stimuli. ⋯ The majority of QST parameters are normally distributed only after logarithmic transformation (i.e. secondary normalization). With QST a complete somatosensory profile can be obtained within 1 h. The QST is a suitable method for characterizing the function of the somatosensory system in clinical trials and also in clinical practice as a diagnostic procedure.
