From 1973 to 1982 six children and eight adolescents with extremity melanomas were treated by local excision and adjuvant hyperthermic isolated regional perfusion with Melphalan (L-phenylalanine mustard, manufactured by Burroughs Wellcome Company, Research Triangle Park, NC). The median Breslow thickness of the melanomas was 2.7 mm (range, 1 to 15 mm). According to the M.D. Anderson classification, nine patients were in Stage IA and five were in Stage IIIB. The median follow-up period was approximately 10 years. Distant metastases developed in three patients (21%) (one patient was in Stage IA [11%] and two patients were in Stage IIIB [40%]). In two cases the development of distant metastases was preceded by local recurrence (14%). The 5-year survival rate was 93%. The 10-year survival rate was 81%. The high survival rate, even for patients with unfavorably thick melanomas, seems to be attributable to isolated regional perfusion.

Two novel yeast strains, NYNU 236247 and NYNU 23523, were isolated from the leaves of Hance, collected in the Tianchi Mountain National Forest Park, Henan Province, central China. Phylogenetic analysis of the D1/D2 domain of the large subunit rRNA gene and the internal transcribed spacer (ITS) region revealed the closest relatives of the strains are three described species: , and . The novel species differed from the type strains of these three species by 12 to 22 nucleotide substitutions and 1 gap (~2.

Aims: The gastrointestinal (GI) tract is composed of distinct sub-regions, which exhibit segment-specific differences in microbial colonization and (patho)physiological characteristics. Gut microbes can be collectively considered as an active endocrine organ. Microbes produce metabolites, which can be taken up by the host and can actively communicate with the immune cells in the gut lamina propria with consequences for cardiovascular health.

In chick embryos prior to primitive streak formation, the outermost extraembryonic region, known as the area opaca (AO), was generally thought to act only by providing nutrients and mechanical support to the embryo. Just internal to the AO is a ring of epiblast called the marginal zone (MZ), separating the former from the inner, area pellucida epiblast. The MZ does not contribute cells to any part of the embryo but is involved in determining the position of primitive streak formation from the adjacent area pellucida epiblast.

The increasing incidence of infections attributed to hypervirulent carbapenem-resistant (Hv-CRKp) is of considerable concern. Bacteriophages, also known as phages, are viruses that specifically infect bacteria; thus, phage-based therapies offer promising alternatives to antibiotic treatments targeting Hv-CRKp infections. In this study, two isolated bacteriophages, Kpph1 and Kpph9, were characterized for their specificity against the Hv-CRKp NUHL30457 strain that possesses a K2 capsule serotype.

We report the case of an 18-month-old boy who developed a phototoxic skin reaction to terbinafine on his scalp, ears, and face in the form of disseminated erythematous plaques, which resembled subacute lupus erythematosus (SCLE) in their clinical presentation. Skin changes appeared a short time after the boy was exposed to sunlight during the period of time when he was treated with oral terbinafine due to Microsporum canis fungal scalp infection. Tinea capitis is a common dermatophyte infection primarily affecting prepubertal children (1).
