Dignity in maternity care
Published in Milika Ruth Matiti, Lesley Baillie, Paula McGee, Dignity in Healthcare, 2020
The notion of labouring in front of other people makes mothers feel they are on display and having their ability to cope examined by others. Prospective mothers described how during labour they were going to remain mobile, dressed and maintain a sense of dignity throughout. In reality they found themselves in a public environment, on display and in fear of impending events due to the observation of others. The onset of labour is associated with onset of pain, however minor. Often, as seen during participant observation, mothers laboured in wards behind closed curtains resulting in other mothers overhearing them during labour without witnessing the event. This can be linked to the experience of visiting the dentist, where the dental drill is heard and the level of perceived pain we are going to experience enhanced, even before we have entered the surgery. Overhearing another mother’s pain was deemed to be an extensive privacy breach at what mothers perceived to be a private time. There were people in the early stages of labour in beds around this ward with only a curtain around them, who were clearly in pain, there were people moaning and so on and I thought “I can’t face this” … I thought that there was no privacy for me.There were all these women, I think it was busy downstairs [on the delivery suite] and they would be walking up and down, moaning in pain and waiting to go down and we would have paid the midwives not to hear that.

A similar process may also be taken, if necessary, regarding other stress-arousing objects, such as the syringe (giving it to the patient to hold in his/her hand, gentle gradual insertion into the oral cavity, etc.), the dental drill, or any other specific anxiety-evoking objects.
Surgery Procedure for Distal Middle Cerebral Artery Occlusion Model
Published in Yanlin Wang-Fischer, Manual of Stroke Models in Rats, 2008
Yanlin Wang-Fischer, Lee Koetzner
Removing bone from the skull is often a necessary step in preparing an animal for middle cerebral artery occlusion (MCAO). For this purpose, a portable dental drill has been used in many laboratories (Figure 12.1a). In recent years, cordless and rechargeable microdrills have become commercially available. The new cordless microdrill from Stoelting (Figure 12.1b) is designed for research applications that require surgical burrs and trephines. It is made from a lightweight aluminum alloy for balance and control. It is powered by a rechargeable 6-V nickel cadmium battery and can function for up to 8 hours under normal operating conditions. Its average speed is 14,400 rpm (VWR, Cat. No. 100230-730). Its carbide burr drill bits have a shaft diameter of 2.3 mm and are 4.4 cm long. A microdrill from Fine Science Tools (Figure 12.1c) is portable, rechargeable, and high speed, powered by a 7-V nickel cadmium rechargeable battery. This drill operates at approximately 11,000 rpm, runs quietly, and is vibration free. It is provided with its own recharging unit for overnight charging. The drill cannot be overcharged. A sensitive switch allows precise fingertip control of drilling. This microdrill will hold all standard bits and reamers (Cat. No. 18000–17, www.finescience.com). All bits or burrs can be autoclaved, but the drills cannot.
Hypersonic vitrectomy: a novel approach to vitreous removal
Published in Expert Review of Ophthalmology, 2022
Jacob G Light, Hannah Anderson, Sunir Garg
The desire and need to safely and effectively remove vitreous are not new [7]. Reports from the 1600s describe the work of a Dutch surgeon Anton Nuck who removed vitreous from a glaucomatous (‘hydrophthalmic’) eye through scleral and corneal punctures. American surgeon John Collins Warren removed vitreous through corneoscleral incisions in the mid-1800s. Vitreous taps have been described since 1890, when Vernon Ford performed them to remove vitreous opacities [8]. Open-sky vitrectomy was introduced in the 1950s and 1960s. The most important contribution of this was changing prevailing wisdom by showing that the vitreous was not sacred and that complete removal could be advantageous to prevent secondary fibrosis and vitreoretinal traction [9,10]. The first known description of a closed-system vitrectomy system using a small 27-gauge needle containing a dental drill was made by Chouzaburou Haruta of Japan in 1959, pre-dating the more famous device pioneered by Machemer [7]. This paved the way for the contemporary concept of vitreous removal, in which the vitreous gel is delicately sectioned and aspirated from the eye in controlled fashion, in order to minimize large fluid shifts and retinal traction (these concepts remain foundational even today).

Briefly, the animals were anesthetized with Nembutal (50 mg/kg, Serva) and positioned into a stereotaxic frame and the scalp was shaven. An incision was made along the midline of the scalp and the Bregma was exposed. Cortical focal injury was performed unilaterally using 1 mm wide dental drill through the left somatosensory cortex. The drill was inserted 1 mm into the cortex. After surgery, the animals were kept in isolation for 3 h until complete recovery from the anesthesia, and subsequently returned to their home cages in order to avoid social isolation stress (n = 3 per cage). At the end of the recovery period, the animals were decapitated, the brains were removed on ice, and the ipsilateral cortex was collected from each animal for subsequent analysis. Physiological controls (designated as control) for both groups were not subjected to surgery. Cortical tissue from the same animal was used for RNA and protein isolation (n = 5 animals per each time point). For histochemical analysis, entire rat brains (n = 3 animals per each time point) were used. The presented results denote the data of three independent experiments.
Review of the International Literature
Published in American Journal of Clinical Hypnosis, 2020
Shelagh Freedman, Ian E. Wickramasekera
The author presents an article discussing the management and phenomenology of dental phobias in the practice of dentistry. The article reviews and discusses the general impact that dentistry related phobias have on patients and their negative consequences to patients’ overall health. The article discusses some of the common areas of difficulty that patients come to develop anxiety around including the pain of the various procedures as well as contextual experiences such as the noise that a dental drill emits. The author discusses the potential benefit of utilizing hypnosis to assist patients to manage their anxiety, phobia, and procedural pain during the practice of dentistry. The author provides some recommendations for clinical practice and future research in this area.
