Anatomical Guidelines and Technical Tips for Neck Aesthetics with Botulinum Toxin.

Botulinum toxin can be used for various purposes to enhance neck aesthetics, addressing concerns such as platysmal bands, optimizing the cervicomental angle, preventing worsening of horizontal neckline and decolletage lines during aging, submandibular gland hypertrophy, and hypertrophied superior trapezius muscle. Understanding the anatomy of muscles such as the trapezius, platysma, and submandibular gland is crucial for achieving desirable outcomes with botulinum toxin administration. Techniques for injecting botulinum toxin into these muscles are discussed, emphasizing safety and efficacy. Specific injection points and methods are detailed for treating platysmal bands, optimizing the cervicomental angle, addressing submandibular gland hypertrophy, and managing hypertrophied superior trapezius muscle. Careful consideration of anatomical landmarks and potential complications is essential for successful botulinum toxin injections in these areas.

Lichen sclerosus associated with localized scleroderma: dermoscopy contribution

Abstract: Lichen sclerosus is an uncommon inflammatory dermatosis with preferential involvement of the urogenital region. The extragenital involvement is uncommon and is characterized by small rounded macules or papules, pearly white in color. The coexistence of lichen sclerosus and scleroderma plaques in most cases with extragenital location has been reported in the literature. We report a case of lichen sclerosus associated with scleroderma in children, highlighting the importance of dermoscopy in diagnosis.

Vulvodínia: aspectos atuais / Vulvodynia: an update

Vulvodínia é um termo utilizado para descrever dor crônica em queimação na vulva, sem achados físicos objetivos que justifiquem os sintomas. Sua etiologia é desconhecida. Mulheres brancas, sexualmente ativas e na pré-menopausa são as mais acometidas. Entre os possíveis fatores envolvidos na gênese, estão anormalidades de desenvolvimento embrionário, aumento da excreção urinária de oxalato, fatores genéticos e imunológicos, fatores hormonais, anormalidades no assoalho pélvico e neuropatias. O exame clínico detalhado, com caracterização da dor, pesquisa de irritantes locais, inspeção cuidadosa da vulva e busca de pontos dolorosos, além de avaliação do assoalho pélvico, orienta o diagnóstico e o tratamento. Existem vários tratamentos citados, porém pouca evidência científica que comprove a sua eficácia. Deve-se descontinuar a utilização de produtos que possam funcionar como irritantes. O uso de citrato de cálcio pode diminuir a excreção de oxalato na urina. A fisioterapia pode ser empregada nas pacientes com instabilidade do assoalho pélvico. Os antidepressivos tricíclicos e anticonvulsivantes foram utilizados com boa resposta em vários estudos. Além destes, podem ser aplicados, topicamente ou por injeção local, substâncias como anestésicos, corticoides, estrogênios e interferon-alfa. A cirurgia fica reservada para casos extremos, sendo que os resultados na literatura são conflitantes.

Vulvodynia is a term used to describe chronic vulvar pain or discomfort, without signs that explain such symptom. Its etiology is unknown. It is more likely to occur in sexually active, white women in pre-menopausal period. Many factors may be involved in the onset of this condition (anomalies in embrionary development, increased urinary oxalate excretion, genetic and immune factors, hormonal factors, pelvic floor problems and neuropathies). A thorough clinical history must be done, with special attention to the pain characteristics and use of local irritants. Careful vulvar inspection, research of trigger points and pelvic floor evaluation will increase the likelihood of an accurate diagnosis. Many treatment options are described, but there is not enough evidence on their effectiveness. Local irritants should be discontinued. Calcium citrate may decrease urinary oxalate excretion. Physical therapy can be used to treat pelvic floor instability. Tricyclic antidepressants and anticonvulsants showed a good response in some studies. Besides systemic drugs, topic substances or local injections can be applied (anesthetics, estrogens, corticosteroids and alpha-interferon). Surgery should be reserved to unresponsive cases and its effectiveness has been inconsistent in the scientific literature.
