Facial rejuvenation using photodynamic therapy with a novel preparation of ALA and hyaluronic acid in young adults.

Photodynamic therapy (PDT) is a well-established, non-invasive treatment modality that has shown desirable effects such as improvement of fine lines, dyspigmentation, and other signs of photodamage. Many patients seek to decrease, or reverse, effects of sun damage on the skin. Hyaluronic acid (HA), a naturally occurring glycosaminoglycan found in the body, has enormous potential to bind water which allows the skin to retain moisture and maintain elasticity. Topical application of HA has been found to produce anti-wrinkle effects. We conducted a pilot case series evaluating the safety and efficacy of a commercially available 2% 5-aminolevulinic acid (ALA) gel with hyaluronic acid (ALA-HA) and light-emitting diode-red light (LED-RL) for facial rejuvenation as determined by clinical assessments and digital skin analysis of rhytides, pore size, and erythema. All patients noted improvement of their skin and experienced minimal pain during PDT. Evaluation by dermatologists demonstrated significant improvement in overall skin appearance. Digital analysis of photographs revealed improvement of skin spots, wrinkles, pores, texture, UV spots, brown spots, red areas, and porphyrins. Our findings demonstrated safety and efficacy of this novel preparation of photodynamic gel with HA and subsequent activation with LED-RL.

Bouveret Syndrome: When a Stone Cannot Pass the Pylorus.

Bouveret syndrome, a rare cause of intestinal obstruction, occurs by passage of a gallstone through a cholecystoduodenal fistula into the intestinal lumen. Presenting symptoms are nausea, vomiting, and abdominal pain. In some cases, chronic symptoms result in weight loss. Typically, the syndrome is diagnosed via x-ray, ultrasound, or computed tomography. Treatment options are endoscopic or surgical. Endoscopic approaches include mechanical lithotripsy, electrohydraulic lithotripsy, stone extraction, laser lithotripsy, extracorporeal shockwave lithotripsy, and/or duodenal stenting. When stone fragments migrate distally, surgical removal becomes necessary. We describe a distinct endoscopic treatment via stone breakage, followed by pushing the fragments of the stone into the jejunum, resolving the intestinal obstruction.
