Background: Calcium hydroxyapatite (CaHA) is a well-established collagen stimulator. In recent years, it has been increasingly used in hyperdiluted form as a biostimulatory agent rather than a volumizing filler to improve skin quality and firmness in both facial and corporal areas. However, guidelines on the techniques required to achieve optimal results are still lacking. The objective of this study was to develop a consensus recommendation for the safe and effective use of hyperdiluted CaHA for face and body biostimulation. Methods: A team of 10 experts with extensive experience in dermal fillers and biostimulatory treatments for facial and body rejuvenation convened for a live meeting. Consensus was defined as approval by 70%–89% of all participants, whereas agreement of ≥90% denoted strong consensus. Results: For most items, the group achieved a majority consensus. Recommendations have been provided for the face, neck, décolletage, buttocks, thighs, arms, abdomen, knees, and elbows with detailed injection techniques, providing information on insertion points, dosages, and volumes for both needle and cannula injections as well as the number of treatment sessions and intervals. Conclusions: The expert consensus supports and provides guidance for the use of CaHA as a biostimulatory agent for face and body rejuvenation. However, further clinical studies are necessary to provide physicians with the best evidence for the best treatment practices.

BACKGROUNDSkin cancer is the most common malignancy and can be treated in various ways. One treatment modality is Mohs micrographic surgery. Due to the increasing incidence of skin cancer in the last decades, there is a need for improvement of the Mohs technique to optimize its effectiveness. OBJECTIVEThe aim of this study was to evaluate the use of dermoscopy to guide demarcation of Mohs micrographic surgery margins and ascertain whether this method can reduce operative time and, therefore, reduce surgical morbidity and cost. METHODS AND MATERIALSThe sample comprised 44 patients who underwent Mohs micrographic surgery, allocated into two groups: the control group and the intervention group. In the latter, surgical margins were guided by dermoscopy. RESULTSThere were no statistically significant differences between the two groups by chi-square analysis (p = 0.399). CONCLUSIONAlthough outcomes were similar in the two groups, demonstrating that dermoscopy does not help in the demarcation of surgical margins for Mohs micrographic surgery, the study provides a practical proposal for improvement of the Mohs technique.

BACKGROUNDMasseter hypertrophy has been treated with botulinum toxin injections because of esthetic complaints especially in Asians.OBJECTIVESThe goal of the present study was to evaluate the efficacy of abobotulin toxin use in masseter hipertrophy treatment in Brazilians.METHODSTen Brazilian female patients with masseter hypertrophy were subjected to injections of 90U of abobotulinum toxin A applied on each side respecting the safety zone stabilished in literature and were followed up for 24 weeks.RESULTSWhen analyzing the coefficients between measures of middle and lower third of the face obtained from standardized photographs, an increase was observed, with statistical significance at 2 weeks (p=0.005) and 12 weeks (p=0.001). The progression of lower third reduction was 3.94%, 5.26%, 11.99%, and 5.47% (2, 4, 12, and 24 weeks respectively). All patients showed improvement in bruxism after treatment. Observed adverse effects were masticatory fatigue, smile limitation, and smile asymmetry.CONCLUSIONThe use of abobotulinum toxin A for masseter hypertrophy is effective in Brazilians and reached its maximum effect of facial thinning at 12 weeks. Smile limitation had a higher incidence compared to that reported in the literature and may result from risorius muscle blockage caused by toxin dissemination. Despite its side effects, 80% of the patients would like to repeat the treatment.

Condição adquirida, sistêmica, caracterizada por tromboses recorrentes no sistema arterial, venoso ou ambos, a síndrome antifosfolípide pode ser primária ou secundária, esta última mais associada ao lúpus eritematoso sistêmico e menos freqüentemente a infecções, fármacos e outras doenças. São marcadores sorológicos da síndrome antifosfolípide os anticorpos antifosfolípides anticoagulante lúpico e anticardiolipina. O critério diagnóstico primário inclui trombose arterial ou venosa e morte fetal recorrente. Cerca de 41% dos pacientes apresentam lesões cutâneas como primeiro sinal da síndrome, que também pode provocar livedo reticular, ulcerações cutâneas, vasculite livedóide, entre outras manifestações. Seu controle consiste principalmente no tratamento e profilaxia da trombose com anticoagulantes e antiagregantes plaquetários.

Glabella and forehead lines can be effectively and safely reduced with neurotoxin alone as well as neurotoxin in combination with fillers. Combination treatment may provide a slightly better cumulative benefit and also increase the persistence of effect.

Background: Adapalene has been previously evaluated as a treatment for actinic keratosis (AK) and solar lentigines and shown to improve signs of photoaging. Objectives: To evaluate whether adapalene 0.3% gel is non-inferior to tretinoin 0.05% cream as treatment for photoaged skin. Materials & Methods: An investigator-blinded, parallel-group comparison study was conducted in Brazil. Subjects were randomised in a 1:1 ratio to receive, once daily, adapalene 0.3% gel or tretinoin 0.05% cream. Subjects were evaluated at Weeks 1,4,8,12,16,20 and 24, based on clinical signs of cutaneous photoaging, histopathological and digital morphometric findings, as well as safety and tolerability. Results: A comparison of clinical efficacy showed that both treatments did not differ significantly regarding clinical evaluation of the following criteria: global cutaneous photoaging, periorbital wrinkles, ephelides/melanosis, forehead wrinkles, and AK. Conclusion: Adapalene 0.3% gel showed non-inferior efficacy to tretinoin 0.05% cream as treatment for photoaged skin, with a similar safety profile. Adapalene 0.3% gel may therefore be considered a safe and effective option for the treatment of mild or moderate photoaging.

Alopecia frontal fibrosante é forma progressiva de alopecia cicatricial. Os casos iniciais foram relatados a partir 1994, na Austrália, em pacientes do sexo feminino pós-menopausa. Desde então inúmeros casos foram descritos na literatura sugerindo que ela é mais prevalente do que inicialmente se supunha. Seu curso progressivo se assemelha ao da alopecia androgenética; histologicamente, entretanto, o infiltrado liquenóide é evidente. O artigo relata seis casos brasileiros e discute a alopecia frontal fibrosante dentro do grupo das alopecias cicatriciais, como variante do líquen plano pilar.

Piloleiomioma é tumor benigno de músculo liso que tem origem no músculo eretor do pêlo. Pode ocorrer isoladamente ou em grande número. Apresenta-se doloroso, sensível ao frio, toque, pressão e emoção. Relata-se caso de um homem com nódulos intradérmicos compostos por fibras de músculo liso. A imuno-histoquímica mostra-se positiva para desmina e actina, confirmando o diagnóstico.
