Accurate assessment can improve the consistency and quality of surgery outcomes. This study outlines a non-invasive method to measure breast volume using a whole body 3D laser surface anatomy scanner, the Cyberware WBX. It expands on a previous publication where this method was validated against patients undergoing mastectomy. It specifically outlines and expands the computer-aided anthropometric (CAA) method for extracting breast volumes in a non-invasive way from patients enrolled in a breast reduction study at Flinders Medical Centre, South Australia. This step-bystep description allows others to replicate this work and provides an additional tool to assist them in their own clinical practice and development of designs.

This results in good information about the gender, ethnicity, age, income and other characteristics of the target market. In this paper we will show how this can be taken one step further with large anthropometric databases and small fit studies to better target the market, improve sales and reduce waste, through improved fit, faster product development and tighter inventory control. The improvement in population accommodation with good selection of the sizes will be quantified and illustrated using data from the WEAR Association database. An example of the creation of the “fit map” for an apparel item will be provided and compared against a priori assumptions about the range of fit. Then a comparison of raw data versus data weighted to the target market will be illustrated.

Doctors in training often encounter these patients and are expected to perform diagnostic and therapeutic pleural procedures with confidence and safely. However, pleural procedures can be associated with significant complications, especially when performed by less experienced. Structured training such as use of training manikin and procedural skills workshop may help trainee doctors to achieve competence. However, high costs involved in acquiring simulation technology or attending a workshop may be a hurdle. We hereby describe a training model using a simple manikin developed in our institution and provide an effective way to document skill acquisition and assessment among trainee medical officers.Study designThis was a prospective observational study. The need for training, competence and confidence of trainees in performing pleural procedures was assessed through an online survey. Trainees underwent structured s...

In women with breast hypertrophy, volumetric assessment assists in planning the amount of tissue to be removed during breast reduction surgery to achieve breast symmetry. Further, in jurisdictions where restrictive surgical guidelines exist, measurement of intact breast volume is essential in order to justify breast reduction surgery. Not all practitioners have access to magnetic resonance imaging (MRI) or three dimensional (3D) laser scanning facilities, so the purpose of this study was to determine whether water displacement of the intact breast is an effective substitute method of measurement in women with breast hypertrophy. Methods: A prospective cohort study was undertaken to measure breast volume using water displacement and 3D laser scanning in breast hypertrophy patients. The volume of a total of 322 breasts were determined usin...

Sustainable sizing involves a set of methods good for both the environment (sustainable environment) and business (sustainable business). Sustainable sizing methods reduce (1) materials used, (2) the number of sizes or adjustments, and (3) the amount of product unsold or marked down for sale. This reduces waste and cost. The methods can also increase sales by fitting more people in the target market and produce happier, loyal customers with better fitting products. This is a mini-review of methods that result in more sustainable sizing practices. It also reviews and contrasts current statistical and modeling practices that lead to poor fit and sizing. Fit-mapping and the use of cases are two excellent methods suited for creating sustainable sizing, when real people (vs. virtual people) are used. These methods are described a...

How do definitions work for women who deviate from the conventional body shape? Does the measuring instrument matter? Waist is conventionally understood to be a measurable zone within the abdominal region of the torso, a zone of considerable importance. There needs to be a good consistent waist definition, one accurate and valid for everyone. Incorrect definition and measurement will result in technical errors, commercial wastage and customer dissatisfaction. This paper investigates the waist's location and size from the point of view of garment construction for 90 adult women scanned and manually measured in a breast reduction study at Flinders Medical Center, South Australia. There are differing definitions of the location of the human waist as well as different measuring instruments. This study compares:• Two definitions:• ISO 8559, 2.1.11 and • CAESAR, Waist Circumference Preferred.• Two different instruments:• the traditional tape measure, ...

Our goal is to design, develop, and establish a test to determine whether students can, by touch alone, identify and discriminate between a range of different simulated lesions at different adiposity levels. Methods: Common lesions, breast cancers, and cysts were physically simulated and hidden in a test object referred to as the “tactile landscape” (TL). Ribs, intercostal muscle, and nodularity—normal anatomical features—increased their realistic complexity. Varying depths of features simulated varying degrees of adiposity. A testing protocol was created to determine the testee's ability to identify and discriminate different commonly occurring breast masses using palpation. Five experts (four breast surgeons and one general practitioner) and 20 inexperienced medical students were recruited and tested. Results were compared. ...

Research paper thumbnail of Evaluation of conventional training in Clinical Breast Examination (CBE)

Work

BACKGROUND: Clinical Breast Examination (CBE) is the examination of a women's breasts by a health... more BACKGROUND: Clinical Breast Examination (CBE) is the examination of a women's breasts by a healthcare professional, such as a breast surgeon, family physician or breast-care nurse who is trained to recognise many different types of abnormalities and warning signs in the breast [1]. CBE is particularly important in rural areas and developing countries who have limited access to technology such as mammography. CBE needs to be taught to health professionals like any other clinical skill used by medical professionals in the workplace. CBE in part involves palpation of the breast, that is, determining by touch which breast lumps are normal and which are suspicious in feeling. The gold standard for assessing tactile skills in CBE is seeing whether students can accurately identify and discriminate between different breast lumps also known as masses (IDBM) on actual patients in a clinical setting. However, this is not practical in a medical education setting. Usually the testing methods 'go through the motions' of feeling the breast as part of CBE. So the students' technique is examined either using unrealistic simulation models or using an intimate examination associate (IEA), an actor/volunteer who permits students to examine their intimate body parts such as breast or genitals for teaching purposes. These volunteers do not have any abnormalities so this teaching does not include the actual detection of suspicious lumps. We undertook a study of clinical skill with 10 medical students to examine different methods of assessing novice student clinical skills after a brief training in CBE. OBJECTIVES: This study aims to evaluate the effectiveness of current training and assessment of novice students in CBE and their capacity to identify and discriminate breast masses (IDBM) on actual patients. METHODS: We assessed each student's IDBM ability in an actual clinical situation, a breast clinic with a mixture of eight IEAs and one real patient with a large, easily palpable, putative breast cancer. We recruited 10 clinically inexperienced medical students, who were trained for 30 minutes by two breast surgeons using an IEA. Students were tested in a simulated clinical setting, a breast clinic where each examined 4 IEAs and one patient. The students were blind to who was the real patient and who was an IEA. Patients were examined by a breast surgeon in private prior to the commencement in the study. The breast surgeon recorded any clinical finding on the patients during the initial examination. The surgeon coached each patient on how to mark the students and showed the patient their results so the patients had a benchmark. After each examination was finished the students had four different assessments: 1) patients marked each student, 2) students were independently proctored-that is, marked by an expert, 3) students recorded their clinical findings and 4) students recorded how confident they were that they had the correct findings. Results from different kinds of student assessments were compared.

Detailed research and a methodological design approach led to the development of a new technique for creating lifelike models for teaching CBE. Six multi-layered breast models representing a range of normal human variation for durity (hardness/softness), nodularity (fibro-glandular tissue) and adiposity (fatty tissue) were developed and validated. Various construction materials, MRI scans, traditional casting and three-dimensional (3D) printing were used to build models with lifelike look and feel (biofidelic). The models realistic in anthropometry (size and shape), feel (durity and nodularity) and appearance (skin feel and colouring)visual biofidelity enhances perception of feel incorporate anatomically correct layering of ribs, soft adipose tissue, nodularity and additional signs of breast disease, both benign and pathological. These were validated by four breast surgeons who compared their feel alongside a sample of breast patients (N = 78). Models were rated as 'undecided', 'similar' or 'very similar' to 81% of patients for nodularity and 82% for durity. These are the first models to incorporate normal human variability and be validated with real patients. These novel biofidelic models provide a standardized way of teaching health professionals normal from abnormal.

Yet, many medical students and doctors report they could improve their skills in clinical breast examination (CBE). Training programs using silicone breast simulators improve the lump detection rate. Despite this, medical students and trainees typically perform low in breast examination scores. This indicates current simulation models provide insufficient CBE training. In this study, we have improved breast examination simulators by applying anthropometric data and selecting one very commonly occurring shape in the female population as a model. Aims: To provide a breast model representative of the large size female population and more varied scenarios for breast lump palpation. Method: Comparing the 2002 National Size and Shape Survey of 1,250 adult Australian women, Australian Bureau of Statistics data, and the Civilian American and European Surface Anthropometry Resource Project (CAESAR®), we selected individuals anthropometrically representative of the surveyed population. Combining one woman's body scan, computer-aided design, rapid prototype techniques, and the latest biofidelic (lifelike) silicone technology we created an anatomically correct representation of a real world patient. This model requires trainees to learn that breast examination can be complex and involves a multifaceted approach. Results: A prototype representing women with larger breast size and a relatively high body mass index (BMI) was developed. The individual selected was a large size woman of approximate BMI 30, 82kg and large cup size (D); by our analysis more than 50% of women are C cup or above. Conclusions: Confident and competent breast palpation requires a life-size model that looks and feels lifelike. Currently available breast examination simulators do not model the size and shape of patients encountered. This impedes developing confidence and competence in health care workers who need these skills. Lifelike look and feel require an anatomically correct, multi-layered soft breast construction, incorporating palpable anatomical underlying features, including tumors. ©Veitch et al: Licensee HFESA Inc.
