AI Article Synopsis
- The study aimed to analyze the blood vessel distribution in expanded skin in the mastoid region to inform the design of flaps for ear reconstruction in cases of congenital microtia.
- The researchers observed blood vessel patterns using a light permeation test and developed different flap designs based on these patterns.
- Results showed that five distinct types of vascular distribution were identified among 403 cases, and all flap designs resulted in complete survival, highlighting the importance of vascular knowledge in flap design.
Article Abstract
Objective: To classify the blood vessel distribution of the expanded skin in the mastoid region and its relevance to reasonable and reliable design of the expanded flap for auricular reconstruction in congenital microtia.
Methods: The blood vessel distribution of the expanded skin in the mastoid region was observed by light permeation test. The expanded flaps with different ratio of length to width were designed according to their blood vessel distribution types.
Results: The vascular distribution of the expanded skin in 403 cases was divided into five types. All the flaps survived completely.
Conclusions: The blood vessel distribution type of the expanded skin in mastoid region has great significance for the design of post-auricular expanded flap in auricular reconstruction.

Delivery of therapies into skin is attractive for medical indications including vaccination and treatment of dermatoses but is highly constrained by the stratum corneum barrier. Microneedle (MN) patches have emerged as a promising technology to enable non-invasive, intuitive, and low-cost skin delivery. When combined with biodegradable polymer formulations, MN patches can further enable controlled-release drug delivery without injection.

Primary effusion lymphoma (PEL) is a rare and aggressive B-cell lymphoma typically associated with human herpesvirus 8 (HHV-8) and Epstein-Barr virus infections. It classically presents as a malignant effusion in body cavities, but rarely presents with an extracavitary variant characterized by solid tumors in lymph nodes or extranodal sites such as the gastrointestinal tract, skin, lungs, and nervous system. This case report describes an unusual presentation of primary cutaneous extracavitary PEL in an HIV-positive patient that has only been reported in 8 cases previously.

Background: Cellulitis is an acute bacterial infection of the skin and subcutaneous tissue. The characteristic symptoms of the disease are an area of skin that is swollen, warmth, redness, pain, unknown borderline, tends to expand, and can lead to tissue necrosis. Hyperbaric Oxygen (HBO) is a non-drug treatment, which has the effect of relieving pain, reducing edema, and accelerating the wound healing process for patients with cellulitis.
