Overview on the Causes and Updated Management of Impetigo

Impetigo is the most common bacterial skin infection in children between the ages of 2 and 5. There are two main types: non-vesicular (70% of cases) and bullous (30% of cases). Non-bullous impetigo or impetigo is caused by Staphylococcus aureus or Streptococcus pyogenes and is characterized by honey-colored skin on the face and limbs. Impetigo primarily affects the skin or is a secondary infection with insect bites, eczema, or herpes lesions. Bullous impetigo caused only by S. aureus causes large, relaxed blisters and is more likely to affect the interstitial area. Both types usually resolve within a few weeks without scarring, and complications are rare, the most serious of which is streptococcal glomerulonephritis. Treatment includes topical antibiotics such as mupirocin, retapamulin, and fusidic acid. Oral antibiotic therapy can be used for impetigo with large blisters, or when topical therapy is not practical. Amoxicillin / clavulanate, dicloxacillin, cephalexin, clindamycin, doxicillin, minocycline, trimetoprim / sulfamethoxazole, and macrolides are optional, but penicillin is not.

Coix Seed Consumption Affects the Gut Microbiota and the Peripheral Lymphocyte Subset Profiles of Healthy Male Adults

A systematic examination of the effects of traditional herbal medicines including their mechanisms could allow for their effective use and provide opportunities to develop new medicines. Coix seed has been suggested to promote spontaneous regression of viral skin infection. Purified oil from coix seed has also been suggested to increase the peripheral CD4+ lymphocytes. We, herein, attempt to shed more light on the way through which coix seed affects the human systemic immune function by hypothesizing that a central role to these changes could be played through changes in the gut microbiota. To that end, healthy adult males (n = 19) were divided into two groups; 11 of them consumed cooked coix seed (160 g per day) for 7 days (intervention), while the other eight were given no intervention. One week of coix seed consumption lead to an increase of the intestinal Faecalibacterium abundance and of the abundance (as % presence of overall peripheral lymphocytes) of CD3+CD8+ cells, CD4+ cells, CD4+CD25+ cells, and naïve/memory T cell ratio. As the relationship of microbiota and skin infection has not been clarified, our findings could provide a clue to a mechanism through which coix seed could promote the spontaneous regression of viral skin infections.

Aktivitas Antioksidan Ekstrak Etanol Temu Blenyeh (Curcuma Purpurascens Blumae) Dengan Metode Dpph (1,1 Diphenyl-2-Picrylhydrazyl)

ABSTRACTAntioxidants have a function to scavenge and neutralize oxidation effect caused by free radicals by preventing the formation of radicals. Temu blenyeh (Curcuma purpurascens Bl) is one of the curcuma species which is still under-researched. Traditionally, temu blenyeh is used to treat stomachache, cough, itch, and skin infection. Some studies show that temu blenyeh extract had antioxidants activity and anti-cancer. The extract contains flavonoid, terpenoid, steroid, triterpenoid, essential oil. The study aimed to determine antioxidant activity of ethanol extract of temu blenyeh using DPPH method. Temu blenyeh was extracted by maceration with 96% ethanol solvent. The antioxidants activity test described that the value of IC50 was 48.697 ppm. Keywords: Temu blenyeh, DPPH, antioxidants Abstrak Antioksidan berfungsi untuk menangkal dan menetralisasi efek oksidasi yang disebabkan radikal bebas dengan cara mencegah terbentuknya radikal. Temu blenyeh (Curcuma purpurascens Bl) salah satu spesies curcuma yang masih sedikit diteliti. Temu blenyeh secara tradisional digunakan untuk mengobati sakit perut, batuk, gatal, dan infeksi kulit. Beberapa penelitian membuktikan bahwa ekstrak rimpang temu blenyeh memiliki aktivitas antioksidan dan anti kanker. Temu blenyeh mengandung flavonoid, terpenoid, steroid, triterpenoid dan minyak esensial. Penelitian ini bertujuan untuk mengetahui adanya aktivitas antioksidan pada ekstrak etanol temu blenyeh menggunakan metode DPPH. Temu blenyeh diekstraksi dengan metode maserasi menggunakan pelarut etanol 96%. Dalam penelitian uji aktivitas antioksidan ekstrak etanol temu blenyeh menunjukkan hasil nilai IC50 sebesar 48,697 ppm.

Infiltrative-Suppurative Form of Scalp Microsporia in a Child with Generalized Pustular Psoriasis of von Zumbusch: Clinical Case

Background. This article discusses issues of diagnosis and management of pustular psoriasis in a child associated with recurrent dermatomycosis, immunopathogenetic mechanisms of pustular psoriasis, its course and prognosis. Clinical Case Description. The clinical case of infiltrative-suppurative form of scalp microsporia in 11 years old child with long-term psoriasis vulgaris and its transformation to generalized pustular psoriasis (von Zumbusch) is described. The need of immunosuppressive therapy prescription for severe psoriasis was challenged with fungal skin infection as immune suppression would lead to its recurrent course. Conclusion. Combination treatment (systemic glucocorticosteroids, methotrexate, antibiotics, and griseofulvin) resulted in clinical and laboratory recovery for microsporia in a child with generalized pustular psoriasis.

Chemerin-Derived Peptide Val66-Pro85 Is Effective in Limiting Methicillin-Resistant S. aureus Skin Infection

Chemerin-derived peptide Val66-Pro85 (p4) restricts the growth of a variety of skin-associated bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). To better understand the antimicrobial potential of chemerin peptide, we compared p4 activity against MRSA in vitro to cathelicidin LL-37, one of the key endogenous peptides implicated in controlling the growth of S. aureus. The efficacy of p4 was also validated in relevant experimental models of skin pathology, such as topical skin infection with community-acquired MRSA, and in the context of skin inflammatory diseases commonly associated with colonization with S. aureus, such as atopic dermatitis (AD). We showed that p4 collaborates additively with LL-37 in inhibiting the growth of S. aureus, including MRSA, and that p4 was effective in vivo in reducing MRSA burden. p4 was also effective in reducing levels of skin-infiltrating leukocytes in S. aureus-infected AD-like skin. Taken together, our data suggest that p4 is effective in limiting S. aureus and, in particular, MRSA skin infection.
