The integrity of human skin is central to the prevention of infection. Acute and chronic wounds can develop when the integrity of skin as a barrier to infection is disrupted. As a multi-functional organ, skin possesses important biochemical and physical properties that influence its microbiology. These properties include a slightly acidic pH, a low moisture content, a high lipid content (which results in increased hydrophobicity) and the presence of antimicrobial peptides. Such factors have a role to play in preventing exogenous microbial colonisation and subsequent infection. In addition, the properties of skin both select for and enhance colonisation and biofilm formation by certain 'beneficial' micro-organisms. These beneficial micro-organisms can provide further protection against colonisation by potential pathogens, a process known as colonisation resistance. The aim of this paper is to summarise the microflora of skin and wounds, highlighting the role of certain micro-organisms and biofilms in associated infections.

Ablepharon macrostomia syndrome is a rare congenital disorder caused by autosomal-dominant mutations. This condition is characterized by redundant skin, low-set ears, macrostomia, ambiguous genitalia, and underdevelopment of the both upper and lower eyelids. The shortening of the anterior lamella, septum and levator aponeurosis lead to a severe corneal exposure within the first hours of life.

Background: Dermatofibrosarcoma protuberans (DFSP) is a rare, low-grade fibrohistiocytic tumor with malignant potential. It is considered to have a high local recurrence rate due to the characteristic invasion of the finger-like lesion into the soft tissues.
Method: This retrospective study presents details of 20 DFSP patients with a history of surgery and a long follow-up period.

Background: The low incidence and poor prognosis primary trastuzumab resistance (PTR) in HER2-positive breast cancer has limited research into possible treatments. Thus, it remains unclear whether this group of patients could benefit from nontargeting HER2 antiangiogenic therapy.
Patients And Methods: We collected the medical data for HER2-positive patients with PTR who received apatinib 250 mg and trastuzumab-based chemotherapy (ATBC) between March 18, 2017, and March 31, 2022.

Epidemiological studies combining taxonomic and clinical data have been limited globally, particularly Guiyang, the most under-developed economic provincial capital city in southwestern China. A retrospective analysis was performed of dermatophyte epidemiology involving all culture-positive cases received between May 2017 and May 2023 at the Affiliated Hospital of Guizhou Medical University. Phylogenetic analysis was conducted on 391 dermatophyte isolates collected from patients using the rDNA internal transcribed spacer sequences.

Background: Atopic dermatitis (AD) is a chronic, pruritic, and inflammatory dermatosis seen in individuals with an atopic predisposition. This study aimed to examine the immunoreactivity of spexin and TRPM2 in skin samples from patients with AD and MF lesions using immunohistochemical methods.
Materials And Methods: The study utilized a total of 60 skin samples, comprising 20 from AD patients, 20 from MF patients, and 20 from control subjects.
