RESUMO

Several studies have reported the potential of utilizing natural extracts in wound care, emphasizing those with anti-inflammatory and antimicrobial properties. In veterinary medicine, dermal-lesion treatment can be very challenging considering the patient's compliance and awareness of their condition. In this article, six veterinary case reports have been presented to elucidate the advantages of AlpaWash, a topical application utilized in combination with the prescribed medications of the patients, for the purpose of addressing the process of wound healing in three cats and three dogs. All animals were admitted to the veterinary clinic and treated under the supervision of a veterinarian. The cats and dogs were rescued from streets by people who lived in the neighborhood of Cão Bento´s Veterinary. They were admitted for the purpose of receiving medical care due to recent minor injuries or wounds due to a pet fight, preexisting condition, or accident. A veterinarian performed the anamnesis and monitored the animals during the period of treatment with AlpaWash. In each case report, the veterinarian observed significant improvement in the wound closures, and lesions healed within a couple of weeks to a couple of months depending on the case. The outcomes demonstrate the benefits of AlpaWash topical application and suggest that AlpaWash may be an alternative vehicle for compounded preparations in wound management.

RESUMO

Abstract Tongluo-Qutong rubber plaster (TQRP), a typical Chinese patent medicine that contains 13 different herbal remedies, is widely used in clinical practice for the treatment of cervical spondylosis and osteoarthritis. However, due to a lack of in vitro transdermal studies, the active ingredients of TQRP have not been fully elucidated. This presents a huge obstacle for quality evaluation, pharmacokinetic studies and clinical safety assessment of TQRP. In this work, a UPLC/UV/MS/MS method was established and validated to evaluate five analytes in TQRP. The validation demonstrated linearity (r > 0.99), specificity (no co-eluting peaks at the retention times of the analytes), and precision (RSD < 15%) within acceptable parameters. A skin permeation study was performed to determine the concentrations of drugs delivered to the dermis. The 24-hour cumulative permeation of ferulic acid, aleo-emodin, emodin and piperine were 303.68, 709.31, 671.06 and 25561.01 ng/cm2, respectively. According to the fitting data of the TQRP active components, skin permeation was mainly due to a combination of passive diffusion and drug release after matrix erosion

RESUMO

Skin lesions of patients affected by non-ulcerated cutaneous leishmaniasis (NUCL) caused by L. (L.) infantum chagasi are characterized by lymphohistiocytic inflammatory infiltrate associated with epithelioid granuloma and scarce parasitism. However, the in situ cellular immune response of these patients is unclear. Therefore, the aim of the present study was to characterize the cellular immune response in the skin lesions of patients affected by NUCL. Methods Twenty biopsies were processed by immunohistochemistry using primary antibodies to T lymphocytes (CD4, CD8), NK cells, B lymphocytes, macrophages, nitric oxide synthase and interferon-gamma. Results Immunohistochemistry revealed higher expression of all cellular types and molecules (IFN-γ, iNOS) in the dermis of diseased skin compared to the skin of healthy individuals (p < 0.05). Morphometric analysis performed in the skin lesions sections showed the predominance of CD8+ T lymphocytes in the mononuclear infiltrate, followed by macrophages, mostly iNOS+, a response that could be mediated by IFN-γ. Conclusion Our study improves knowledge of the cellular immune response in non-ulcerated or atypical cutaneous leishmaniasis caused by L. (L.) infantum chagasi in Central America and pointed to the pivotal participation of CD8+ T lymphocytes in the host defense mechanisms against the parasite in patients with NUCL.(AU)

RESUMO

Se presenta una mujer de 18 años de edad sin antecedentes familiares ni personales de interés que consulta por tricoepiteliomas en cara y cilindromas en cuero cabelludo. En el examen físico hallamos máculas hipomelanóticas en abdomen y en muslo, y un fibroma periungueal en el 5º dedo de pie derecho que obligaron a descartar otras entidades. Se realizó el diagnóstico de síndrome de Brooke-Spiegler, y se revisan los diagnósticos diferenciales de papulosis faciales
