Treatment of Acne With a 1726 nm Laser, Air Cooling, and Real-Time Temperature Monitoring, Software-Assisted Power Adjustment to Achieve a Temperature Endpoint With Selective Sebaceous Gland Photothermolysis.

Objectives: This work highlights the methods used to develop a multi-pulse 1726 nm laser system combined with bulk air-cooling for selective sebaceous gland (SG) photothermolysis using thermal imaging and software algorithms. This approach enables treating to a desired tissue temperature and depth to provide a safe, effective, reproducible, and durable treatment of acne.

Methods: We designed and built a 1726 nm laser system with a 40 W maximum power output, a highly controlled air-cooling device, and a thermal camera in the handpiece, which permits real-time temperature monitoring of the epidermis.

Biparietal Osteodystrophy Visualized on a Dermatologist's Scalp Examination.

Biparietal osteodystrophy, also known as biparietal thinning, is an uncommon illness that causes symmetrical thinning of the parietal bones. It primarily affects women in their sixth and seventh decades of life. We present a case of a 73-year-old female with osteoporosis and osteoarthritis who visited a dermatology clinic with a bulging mass around her vertex scalp, accompanied by episodes of dizziness and blurred vision.

Facial Contouring Through Jaw Exercises: A Report of Two Cases Examining Efficacy and Consumer Expectations.

This study examines the efficacy of jaw exercising products for facial contouring. The two individuals used a commercially available jaw exerciser for approximately three months, following the provided instructions. Neither case reported noticeable changes in jaw appearance based on subjective measurements.
