The purpose of this study was to compare the results of two- (2D) and three-dimensional (3D) measurements for the alveolar molding effect in patients with unilateral cleft lip and palate. The sample consisted of 23 unilateral cleft lip and palate infants treated with nasoalveolar molding (NAM) appliance. Dental models were fabricated at initial visit (T0; mean age, 23.5 days after birth) and after alveolar molding therapy (T1; mean duration, 83 days). For 3D measurement, virtual models were constructed using a laser scanner and 3D software...

Diaper wearing elderly with functional impairments and/or incontinence is at high risk of contracting urinary tract infections. Nurses struggle with collection of urine samples for analysis. Therefore, a smartphone application is under development as a rapid screening device to work in conjunction with a colorimetric diaper assay that collects and tests urine within a diaper. The focus of this work is to make a practical and useful tool that medical personnel (the user) can use for rapid screening on patients in the field, only with a smartphone and assay available...

With the increased prevalence of retinal pathologies, automating the detection and progression measurement of these pathologies is becoming more and more relevant. Color fundus photography is the leading modality for assessing retinal pathologies. Because eye fundus cameras have a limited field of view, multiple photographs are taken from each retina during an eye fundus examination. However, operators usually don't indicate which photographs are from the left retina and which ones are from the right retina...

It is well known that an earlobe crease (ELC) is related with cardiovascular disease. However evaluation of ELC has been carried out subjectively. We propose a novel system for objective and quantitative evaluation of ELC characteristics. The outline of earlobe was detected using the Canny edge detector. The number of ELCs and the ratio of the ELC length for the lobule from photographs of bilateral earlobes were calculated from the extracted outline of earlobes. Our system's validity for ELCs detection was compared with doctors' diagnosis using sensitivity and specificity analysis...

This paper proposes the use of an adaptive model to measure the width of retinal vessels in fundus photographs. It is based on the hypothesis that the Higuchi's dimension of the cross-section is proportional to the vessel diameter. This approach does not require image segmentation and binarization of the vessels and therefore is suitable for machine based measurements. The model is developed using a synthetic image of the vessel of known diameter and added noise. As a first step, the vessel cross-section profiles were manually obtained and analyzed using Higuchi's fractal dimension method...

General uroflowmetry method involves the risk of nosocomial infections or time and effort of the recording. Medical institutions, therefore, need to measure voided volume simply and hygienically. Multiple cylindrical model that can estimate the fluid flow rate from the photographed image using camera has been proposed in an earlier study. This study implemented a flow rate estimation by using a general-purpose camera system (Raspberry Pi Camera Module) and the multiple cylindrical model. However, large amounts of noise in extracting liquid region are generated by the variation of the illumination when performing measurements in the bathroom...

Previous scar scales have focused on verbal descriptions. A nonverbal visual assessment tool would provide a simple way for patients and physicians to quantify scar appearance. The authors sought to use a validated visual assessment tool for linear surgical scars to assess linear scars on the face and to determine whether patients and surgeons rate scars similarly. A total of 143 patients with linear facial scars resulting from repair of Mohs micrographic surgery defects used the visual assessment tool to rate their surgical scar...

BACKGROUND: Surgical reconstructive planning following Mohs surgery can be a difficult subject for dermatology residents to master. Prior research demonstrates that active learning is preferred and more effective compared to passive learning models and that dermatology residents desire greater complexity and volume in surgical training. We present a novel, active, problem-based learning tool for the education of Mohs reconstruction with the goal of improving residents' ability to plan surgical reconstructions...

The identification of bodies through the examination of skeletal remains holds a prominent place in the field of forensic investigations. Technological advancements in 3D facial acquisition techniques have led to the proposal of a new body identification technique that involves a combination of craniofacial superimposition and photogrammetry. The aim of this study was to test the method by superimposing various computerized 3D images of skulls onto various photographs of missing people taken while they were still alive in cases when there was a suspicion that the skulls in question belonged to them...

Marsh rice rats (Oryzomys palustris) fed a pelleted diet high in sucrose and casein have been used as a model for moderate to severe periodontitis. Here we characterize the prevalence, location, and histopathologic features of food-impaction lesions (FIL), a unique type of oral event, in rice rats fed standard pelleted rodent chow from weaning until 34 wk of age. Healthy female rats (n = 90; age, 4 wk) were weaned into groups (n = 10 to 24) and were euthanized at 4, 16, 22, 28, or 34 wk of age. At necropsy, high-resolution photographs of the 4 jaw quadrants were examined by 3 independent observers to determine the presence, number, and location of FIL...
