Therapeutic options for acne scars include subcision and suction with microdermabrasion, but these treatment modalities have not been studied in conjunction. To compare effectiveness of subcision alone versus subcision with suction for the treatment of facial acne scars. Randomized, split-faced, evaluator-blinded control trial.

The method involves a feature extraction stage to form a bank of 473 features considering different types such as intensity, texture and shape. The feature selection task is carried out on a high-dimensional feature bank, where the search space is denoted by O(2n) and n=473.

We surveyed the Society for Dermatology Hospitalists to better characterize the impact of COVID-19 on teledermatology use by inpatient dermatology providers, particularly on provider perceptions of teledermatology. Prior to the COVID-19 pandemic, 40% (8/20) of surveyed providers had used telehealth at their institution to help perform inpatient consults, while 90% (18/20) adapted use of teledermatology during the pandemic.

Objective: To determine whether the level of pain associated with local anesthetic injections prior to each Mohs stage increases with subsequent Mohs stages.
Methods: Multicenter longitudinal cohort study.
Background: Laser hair removal is associated with moderate acute pain.
Objective: To compare effectiveness of ice pack to topical lidocaine-prilocaine for pain reduction during axillary laser hair removal.
Methods: Participants were randomly assigned to receive topical anesthetic to one axilla and ice packs to the other before each of 3, monthly 810 nm diode laser sessions.
Background: To reduce complications associated with central venous catheter (CVC) insertions, local accreditation programs using a supervised procedural logbook are essential. To increase compliance with such a logbook, a mobile app could provide the ideal platform for training doctors in an adult intensive care unit (ICU).
Objective: The aim of this paper was to compare trainee compliance with the completion of a logbook as part of a CVC insertion accreditation program, before and after the introduction of an app-based logbook.
Heart diseases are the most important causes of death in the world and over the years, thestudy of cardiac movement has been carried out mainly in two dimensions, however, it is important toconsider that the deformations due to the movement of the heart occur in a three-dimensional space.The 3D + t analysis allows to describe most of the motions of the heart, for example, the twistingmotion that takes place on every beat cycle that allows us identifying abnormalities of the heartwalls. Therefore, it is necessary to develop algorithms that help specialists understand the cardiacmovement.

In image analysis, it is common to use a vision-based approach for fall detection and classification systems due to the recent exponential increase in the use of cameras. Moreover, deep learning techniques have revolutionized vision-based approaches.

Recently, we reported on the association of the gene (encoding for δ-sarcoglycan) polymorphisms with AMD. However, the functional consequence of Sgcd alterations in retinal degeneration is not known.
View Article and Find Full Text PDFFalls, especially in elderly persons, are an important health problem worldwide. Reliable fall detection systems can mitigate negative consequences of falls. Among the important challenges and issues reported in literature is the difficulty of fair comparison between fall detection systems and machine learning techniques for detection.
View Article and Find Full Text PDFRobots in assisted living (RAL) are an alternative to support families and professional caregivers with a wide range of possibilities to take care of elderly people. Navigation of mobile robots is a challenging problem due to the uncertainty and dynamics of environments found in the context of places for elderly. To accomplish this goal, the navigation system tries to replicate such a complicated process inspired on the perception and judgment of human beings.

Monitoring of heart rate can be used in many medical and sports applications. Lack of portability and connection problems make traditional monitoring methods difficult to use outside of clinical environments. The computer vision techniques have been shown that some physiological variables as heart rate can be measured without contact.

Background: Little is known about the impact of ultraviolet exposure, climate factors and pollutants on pemphigus.
Aim: To determine whether these factors are associated with pemphigus exacerbation resulting in hospitalization.
Methods: The analysis used data from the 2002-2012 National Inpatient Sample in the USA, including 68 476 920 children and adults, and measurements of relative humidity (%), ultraviolet (UV) index, outdoor air temperature and particulate matter of ≤ 2.
