A new type of touch sensor for detecting contact pressure at human fingertips is presented. Unlike traditional electronic gloves, in which sensor pads are placed between the fingers and the environment surface, this new sensor allows the fingers to directly contact the environment without obstructing the human’s natural haptic senses. The finger touch force is detected by measuring changes in t...

A new method for measuring both the posture of human fingers and shear force at human fingertips is presented. Instead of using a traditional electronic glove with bending sensors embedded along the finger and shear sensors embedded beneath the fingertip, a wearable fingernail sensor is used to measure resulting changes in coloration of the fingernail. Since the sensor is mounted on the fingern...

When the human fingertip is pressed against a surface or bent, the hemodynamic state of the fingertip is altered in a way that is common to all people. Normal force, shear force, and finger extension/flexion all result in visibly distinct patterns of blood volume or perfusion beneath the fingernail. These patterns of blood perfusion can be used not only to monitor the state of the finger, but a...

INTRODUCTION Carbon monoxide poisoning is a very common cause of death in accidental, suicidal, or homicidal cases throughout the world. Fingernail bed manifestation is reported in survivors of carbon monoxide poisoning. CASE PRESENTATION A 40-year-old Caucasian woman was exposed to carbon monoxide when she was sleeping alone in her one-bedroom apartment; fortunately, the beeps from her First...

BACKGROUND Previous clinical trials have not evaluated improvement in nail psoriasis as a primary end point. OBJECTIVE This phase 3 trial evaluated the safety and efficacy of adalimumab in patients with moderate-to-severe fingernail psoriasis and moderate-to-severe plaque psoriasis. METHODS Patients were randomized 1:1 to 40 mg adalimumab every other week or placebo. The primary efficacy en...

A tactile record and playback system will progress tactileology—a new cross-disciplinary field related to sensations—as it enhance its use in the instruction, archiving, analysis of human manipulation. In this paper, we describe two key devices for achieving tactileology: a sensor capturing sense (fingernail color sensor) robotic sensor, both which can detect not only normal force but also tang...

AIM Nail-biting is one of the most frequent deleterious oral habits in children. It can result in systemic diseases or oral traumatic lesion. This report describes a case of gingival abscess in a child due to a fingernail-biting habit. CASE DESCRIPTION A 5-year, 6-month-old female presented gingival swelling and fistula in the primary maxillary left central and right lateral incisors as an un...

Background: Uncuffed endotracheal tubes are still being recommended by most pediatric anesthetists at our Institutes. Different algorithms and formulae have been proposed to choose the best-fitting size of the tracheal tube. The most widely accepted is related to the age of the child [inner diameter [ID] in mm = (age in yr/4) +4; the second is a body, length-related formula (ID in mm = 2 + heig...
