Rabbitswere also used, in pyrogen (fever) tests where a test substance is injected into an ear vein to detect contaminants and the animals were forcibly restrained by their necks in stocks for hours at a time.
The mice were injected into their abdomen with botox and then periodically observed to see how many died. They became increasingly paralysed, eventually gasping for breath and suffocating to death. No pain relief was provided.
Those mice considered unlikely to survive until the next check were taken out into the corridor and crudely killed on the floor by breaking their necks with a ball point pen. New staff, who had never killed mice before, were expected to practise breaking necks on live mice. Sometimes they broke their backs instead of necks causing excruciating agony for the mice.
The rabbits used in pyrogen tests at Wickham Laboratories could be starved for up to 30 hours prior to the animal experiment. During the test they were forcibly immobilised by their necks in stocks for several hours.
Some of the rabbits struggled against these tests and their confinement. Wickham Laboratories acknowledged that their struggling could result in the rabbits sustaining injuries, particularly to their backs.
Some animals suffered in tests that were no longer required by national and international regulations. This made a mockery out of the often-made claim that companies have to do tests because regulators require them.
The UK government is legally obliged to enforce the use of non-animal alternatives to animal tests where they exist, and to ensure that, if animals are used, then it should be the minimum number and with the minimum amount of suffering. Our investigation found that the UK Government failed to meet this obligation at Wickham Laboratories.
In 2010, as a direct result of our efforts, the UK Veterinary Medicines Directorate reviewed all their licenses that included batch tests such as pyrogen tests. This resulted in a change to the licenses for 26 drugs, saving the lives of an estimated 38,000 animals over the next five years. The European Medicines Agency also pledged to review their marketing authorisations.
Sadly, in the UK, whilst the number of mice being used for botulinum toxin batch testing is decreasing, huge numbers are still being used. We believe Wickham are continuing to offer this test to companies that have not yet implemented the non-animal method.
Happily, in the UK, the number of rabbits being used in pyrogen tests has been decreasing since the Wickham investigation and was zero in 2019 and 2020. The European Pharmacopeia announced plans to delete the pyrogen test from EU requirements by 2026.

While plastic surgery can have drastic effects on your appearance, eliminating countless lines and wrinkles in the process, many patients have come to Dr. Christopher R. Hove for cosmetic skin care and nonsurgical anti-aging treatments. These procedures involve no downtime and can be completed in your lunch hour. The most popular nonsurgical treatments at our Paoli, PA practice tend to be cosmetic injectables.
BOTOX injections are cosmetic solutions that help halt the muscle contractions in the injection site. By doing this, the skin around these injection sites, the dynamic wrinkles caused by muscle contractions do not occur and the skin smooths out. The result is a face free from lines and wrinkles, and a better overall appearance in the process.
The exact duration of BOTOX injections can vary from patient to patient. For most BOTOX injection patients, the effects of the injections last for up to six months, sometimes a bit longer. When the effects of the BOTOX therapy have worn off, an additional injection can be performed to prolong the overall results.
Dermal fillers are injectable cosmetics that help fill in wrinkles, lines, and hollows of all kinds. Their role is to add volume to the face where needed, and to reverse the signs of aging in the process. There are many types of dermal fillers available, though the two most well known kinds of dermal fillers tend to be collagen-based or hyaluronic-acid-based.
Dermal fillers are rather versatile, allowing cosmetic surgeons to treat all kinds of problems using these substances. Many fillers are able to address static wrinkles just fine, which means wrinkles that are visible even when a person is not making any kind of facial expression. Fillers can also fill in acne scars, enhance the size and shape of the lips, and add fullness to the face when features appear hollow or sunken in.
Most dermal fillers will last for around six months to a year, with repeat treatments, the results can be prolonged for many additional months on end. Some specially formulated dermal fillers can last even longer, though they may not be ideal for some patients. The right filler for you can be determined as part of the consultation process.
For more information about skin care treatments and anti-aging procedures that do not involve surgery, be sure to contact an experienced cosmetic plastic surgeon.

In July 2021 we performed a systematic search in PubMed and EMBASE to assess the benefits of BTA injection in pelvic floor muscles in women with chronic pelvic pain. Primary outcome was reduction in visual analogue scale (VAS) after treatment. Secondary outcomes evaluated were: reduction of dyspareunia, pelvic floor resting pressure and quality of life. Identified reports were assessed on quality of reporting and risk of bias. Standardized mean difference (SMD) was used to combine and analyse outcomes of the included studies.
There is limited scientific evidence on the effectiveness of BTA injections in pelvic floor muscles in women with chronic pelvic pain. The available studies show that BTA injections significantly reduce pain levels and improve quality of life at 6 months follow-up.
The pathophysiology of chronic pelvic pain is not well understood. Pelvic pain can arise from structures including visceral organs, muscles and the lumbosacral nerves. Every origin has a wide variety of causes, both physical and psychological, which result in secondary muscle contraction and tenderness, known as myofascial trigger points [3]. As many as 85% of these women with CPP have dysfunction of the pelvic musculature [4]. Chronic muscle contraction is associated with a disproportionate release of acetylcholine and other neurogenic inflammatory substances from the neuromuscular junction. This abnormal acetylcholine release triggers increased muscle tension, local hypoxia and tissue distress, leading to a release of more neuropeptides: substance P, calcitonin gene-related peptide and glutamate. Together these neuropeptides activate a complex cascade resulting in a direct stimulation of peripheral nociceptors leading to pain sensation. Autonomic modulation caused by tissue ischemia and decrease of pH potentiates abnormal acetylcholine release, thereby maintaining the hypoxic environment. Central sensitisation occurs when neuropeptides lower the threshold for pain nociception and thereby maintain pain sensation, even after the primary cause of pain nociception has vanished [5, 6]. As such, hypertonic pelvic floor muscles can lead to chronic pelvic pain among other functional problems, such as urinary, sexual and defecatory problems. [7, 8].
First-line treatment of CPP consists of pelvic floor muscle stretching and treatment of myofascial triggerpoints [3]. Unfortunately, this non-invasive treatment is of limited effectiveness. A 2019 systematic review of physiotherapy interventions for CPP concluded that triggerpoint therapy might be useful in management of CPP, but the evidence is inconclusive and the quality of included studies was low [9]. When pelvic floor physical therapy fails, more invasive interventions can be proposed. A multidisciplinary approach is recommended. The injection of botulinum toxin A (BTA) may represent a reasonable second-line intervention.
