Down syndrome is a leading genetic cause of mental retardation. Here, we show high fractal dimensions and Lempel-Ziv complexity and lower minimum path fractal dimension (P < or = .0006) for the oral vascular networks of patients (n = 14) and their unaffected parents. This newly recognized sign may provide a useful phenotypical marker for identifying couples potentially at risk for offspring with Down syndrome.

Polyhydroxyalkanoates (PHAs) are a group of polymers with a variety of monomers, which are extracted from microorganisms and plants. Due to its good biocompatibility, biodegradability, tunable mechanical property and piezoelectricity, PHAs have been widely used in biomedical fields, such as bone, cartilage, nerve, vascular and skin tissue engineering. This review focuses on the in vivo synthesis, metabolism and biological functions of PHA, and the applications of PHAs in the field of tissue engineering and commercial were also summarized and discussed.

Rosacea is a chronic inflammatory disease primarily affecting the central facial region, significantly involving the facial blood vessels and the sebaceous gland units associated with hair follicles. The stellate ganglion block (SGB) technique can restore balance to autonomic nervous function by interrupting the impulse conduction of preganglionic and postganglionic sympathetic nerve fibers, thereby alleviating excessive peripheral blood vessel contraction, enhancing tissue blood supply, balancing hormone secretion, and modulating immune responses. SGB has demonstrated remarkable efficacy in treating various skin conditions affecting the head, face, and neck.

Introduction: Although the diagnosis of tinea capitis is mainly microbiological, the risk of evolution towards cicatricial alopecia in the most severe cases requires empirical treatment based on physical examination and complementary examinations.
Methods: Two patients were evaluated by physical examination, cutaneous ultrasound and microbiological examination.
Results: Ultrasound showed follicular widening and increased vascularization in Doppler mode.
