Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease that affects the apocrine sweat glands and causes inflammatory nodules, abscesses, and painful fistulas in areas such as the armpits, groin, and buttocks. Its impact on patients' quality of life is significant. HS affects 1-4% of the world's population and is associated with factors such as overweight, smoking, and family history. Its pathogenesis is complex, involving inflammation and immune dysfunction. Its diagnosis and treatment are challenging, especially in severe cases. Diagnosis is based on clinical presentation, which is often confused with other skin conditions. It is classified into Hurley stages based on severity. Treatment focuses on controlling symptoms and preventing recurrences. Includes patient education, medical treatment and surgery. The choice of antibiotic therapy depends on the severity and the bacterial strains present. For severe cases, biological therapies are investigated. Surgery, such as simple excision or skin grafts, is effective in controlling the disease. We present a clinical case of a patient with HS, we review the epidemiology, etiopathogenesis and its diagnosis accompanied by the existing therapeutic options.

Surgical outcome of modified Karydakis flap and modified Limberg flab in the management of sacroccygeal pilonidal disease: a comparative study

Introduction: Sacrococcygeal pilonidal disease (SPD) is a chronic suppurative condition of the sacrococcygeal region causing chronic sinus tract or cyst. It is an acquired complex disease more common in young adult males, causing considerable morbidity and long periods of interruption in work or education. From simple conservative techniques to complex flap reconstruction, many debatable treatment options are offered; however clear dynamics toward the widespread use of minimally invasive methods and off-midline flap reconstruction are suggested in all guidelines, which recommend the Karydakis and Limberg flap modification. The plethora of literature compares procedures for identification of a single best treatment approach, which has proven to be difficult. The surgical outcome of both techniques is compared in the present study. Objective: To compare the surgical outcomes of the modified Karydakis flap (MKF) versus the modified Limberg flap (MLF) in SPD. Materials and Methods: The present study was conducted at the general surgery department on SPD patients who were ≥18 years old. A total of 67 participants were included after obtaining the informed consent, with group A comprising 33 patients undergoing the MLF procedure and group B comprising 34 patients undergoing the MKF procedure. Results: The mean patient age was 28.85 (range, 18-44) years old. For the MKF and MLF methods, the average operating duration was 32.5 (range, 25-40) and 54.5 (range, 45-65) minutes, respectively. The MKF approach was found to significantly improve pain score, mean sitting painless time, return to normal activity, wound healing time, and patient satisfaction. Conclusion: Comparative outcomes were seen between both MKF and MLF; however, our findings show that MKF is a more favourable method than MLF with superior outcomes. (AU)

Treatment of Extramammary Paget Disease and the Role of Reflectance Confocal Microscopy: A Prospective Study.

BACKGROUND: Extramammary Paget disease (EMPD) poses treatment challenges. Invasive and noninvasive treatment modalities exist with variable success reported. Reflectance confocal microscopy (RCM) is emerging as an adjuvant diagnostic tool. OBJECTIVE: To evaluate the treatment of EMPD patients and the role of RCM. METHODS: Prospective study. Demographic and tumor characteristics were recorded. Handheld-RCM was performed and correlated with histology. Treatment, clearance, pathology, and follow-up were all recorded. RESULTS: Thirty-six EMPD lesions in 33 patients were included. Mean age was 71.7 years, and 23 were men. Mean number of surgical stages needed to clear margins was 1.9 (SD, 0.9; 1.0-3.0 stages), and mean margin needed to clear was 1.8 cm. Reflectance confocal microscopy correlated well with scouting punch biopsies (kappa, 0.93; p < .001). Disruption of the dermoepidermal junction was associated with invasive EMPD versus in situ (83.3% vs 25.9%) on histology (p = .01). LIMITATIONS: Relatively small sample size. CONCLUSION: Extramammary Paget disease is challenging, and lesion demarcation is of the utmost importance. Using a staged surgical excision approach, the mean margins needed were 1.8 cm, less than previously reported. Nonsurgical modalities, including radiation therapy, imiquimod, or photodynamic therapy can be considered if surgery is not pursued. Reflectance confocal microscopy is a valuable noninvasive imaging modality for the management of EMPD.

Shave Excision Versus Elliptical Excision of Nonpigmented Intradermal Melanocytic Nevi: Comparative Assessment of Recurrence and Cosmetic Outcomes.

BACKGROUND: Nonpigmented intradermal melanocytic nevi (IMN) are benign lesions often removed for cosmetic reasons. There is no consensus as to the best technique for IMN excision. OBJECTIVE: To compare cosmetic outcomes and risk of recurrence after shave excision versus elliptical excision of IMN. MATERIALS AND METHODS: In this randomized clinical trial, patients underwent shave excision or elliptical excision with sutured closure of IMN of the face or back. Recurrence, patient satisfaction, cosmetic outcome, postoperative discomfort, scar size, discoloration, and presence of hypertrophic or keloid scars were evaluated at 3, 6, and 9 months. RESULTS: Overall, 145 nevi were removed from 45 patients (86.7% women, mean age 52.1 ± 12.5 years). The recurrence rate was 11.7%, occurring only after shave excision; 94.1% of recurrences were observed at 3-month follow-up. Shave excision was associated with less discomfort 48 hours after intervention but a greater likelihood of involved lateral and deep margins (p < .001). Scars were larger after elliptical excision and suture than after shave excision (p < .01). The mean patient satisfaction was higher in the shave excision group (p < .004). CONCLUSION: Shave excision of IMN is associated with higher rates of involved surgical margins and recurrence than elliptical excision but provides superior cosmesis and patient satisfaction.

Subcision™ plus poly-l-lactic acid for the treatment of cellulite associated to flaccidity in the buttocks and thighs.

BACKGROUND: There is a growing demand for procedures to treat cellulite. Subcision™ is widely used for cellulite correction, and injectable poly-L-lactic acid (PLLA) has been shown to be an effective option for various body conditions. AIMS: Present the results of combining Subcision™ plus PLLA, in the same session, in patients with cellulite and flaccidity. PATIENTS/METHODS: Twenty-four women underwent Subcision™ followed by PLLA injections. An expert panel of dermatologists evaluated before and after photographs according to Global Aesthetic Improvement Scale (GAIS). Patients also answered a satisfaction questionnaire. RESULTS: The author describes the results, as well as number of sessions and dose used. The most frequent GAIS score was "great improvement." No nodules or granulomas appeared in the treated areas. CONCLUSION: The combination of Subcision™ plus PLLA, in the same treatment session, promotes safe and desirable results for cellulite associated with flaccidity.

Reanimação estática do lábio inferior na paralisia facial como complicação de preenchimento / Static lower lip reanimation as a filler complication of facial paralysis

Procedimentos de rejuvenescimento facial substitutos da cirurgia tradicional tornaram-se cada vez mais populares para promover uma aparência jovial com procedimentos minimamente invasivos, como toxina botulínica injetável, preenchimento de tecidos moles e peelings químicos. No entanto, complicações podem ocorrer mesmo na presença de um injetor habilidoso e experiente. Apresentamos o caso de uma paciente submetida a reanimação labial estática usando retalho dermoadiposo para lesão do nervo facial direito após remoção de nódulos como complicação de preenchimento. A "abordagem modificada de bull horn" foi realizada para elevação do lábio superior em torno das asas nasais e columela e ao longo do sulco nasolabial direito. O retalho foi desepitelizado e obtido. Usando a ponta aberta de uma pequena cânula de lipoaspiração, a porção distal do retalho foi encapsulada e fixada diretamente em C-loop e foram utilizados pontos U, transfixando o retalho para o periósteo do arco zigomático. Nos três anos de seguimento não foram observadas complicações significativas e a paciente não relatou nenhuma limitação funcional ou insatisfação com o aspecto das cicatrizes no sulco nasolabial e ao redor das asas nasais e da columela.

Facial rejuvenation procedures to circumvent traditional surgery have become increasingly popular to promote a youthful appearance with minimally invasive procedures such as injectable botulinum toxin, soft-tissue fillers, and chemical peels. Nevertheless, complications can occur even with an astute and experienced injector. Here we present the case of a patient who underwent static lip reanimation using a dermoadiposal flap for right facial nerve damage following nodule removal as a filler complication. A "modified bulls horn approach" to the upper lip lift was performed around the nasal wings and columella and along the right nasolabial fold. The flap was de-epithelized and harvested. Using the open tip of a small liposuction cannula, the distal portion of the flap was tunneled and fixed directly in a C-loop fashion using U stitches, transfixing the flap to the periosteum of the zygomatic arch. At 3 years follow-up, no significant complications were observed, and the patient reported no functional limitations or dissatisfaction with the scars in the nasolabial fold or around the nasal wings and columella.

Tratamento para queloides: revisão de literatura / Treatment of keloids: a literature review

Introdução: Queloides surgem de resposta excessiva à lesão da derme, resultando em proliferação de fibroblastos, produção exagerada de colágeno e comprometimento da pele sadia adjacente. O diagnóstico é clínico e muitos métodos conservadores e cirúrgicos já foram utilizados para tratamento. Porém, dados da eficácia desses tratamentos são limitados e não há consenso na literatura quanto a melhor técnica a ser empregada, permanecendo uma lacuna que necessita ser preenchida, a fim de que seus usos sejam indicados com maior confiabilidade, em um modelo de medicina baseada em evidências. Métodos: Revisão não sistemática da literatura sobre "queloides" nas bases de dados PubMed, Scielo, MEDLINE, UptoDate e livros-texto das áreas de Dermatologia e Cirurgia Dermatológica. Revisão de Literatura: Foram enumeradas e abordadas as principais informações sobre técnicas cirúrgicas e adjuvantes empregadas para essas lesões, que são: excisão, injeções intralesionais, crioterapia, laserterapia, revestimento com gel de silicone, radioterapia e pressoterapia. Torna-se relevante o levantamento dessas informações, tendo em vista que, além de poder causar dor, prurido e restrição de movimento, o principal motivo da procura de assistência médica para queloide é devido ao aspecto cosmético/estético, e as taxas de reincidência e falha terapêutica ainda são altas, sendo necessário conscientizar o paciente sobre o procedimento e seus efeitos. Conclusão: São muitos os tratamentos disponíveis para o queloide, sejam cirúrgicos ou não, todavia não há consenso sobre uma abordagem universalmente aceita. São necessários mais estudos, com a finalidade de definir a melhor conduta e atingir melhores resultados, visto a qualidade mediana das evidências apresentadas nos estudos.

Introduction: Keloids are characterized by an abnormal response to dermal trauma, resulting in fibroblast proliferation, excessive collagen production, and impairment of adjacent healthy tissue. The diagnosis is clinical, and many conservative and surgical methods can be used as treatments. However, data on the efficacy of these treatments are limited, and there is no consensus regarding the best treatment option. This gap needs to be filled by developing comprehensive evidence-based therapies. Methods: A non-systematic literature review of keloid scars was carried out using PubMed, Scielo, MEDLINE, UptoDate, and dermatology and dermatological surgery textbooks. Literature review: The search retrieved relevant information on surgical and adjuvant therapies used for keloids, including excision, intralesional injections, cryotherapy, laser therapy, silicone gel sheeting, radiation therapy, and pressure therapy. These data are crucial because, in addition to complaints of pain, itching, and restriction of movement, the main reason for seeking treatment for keloids is for cosmetic and aesthetic improvement, and the rates of recurrence and treatment failure are high, emphasizing the importance of creating awareness regarding the available procedures and their effectiveness. Conclusion: Many surgical and adjuvant therapies for keloids are available. Nonetheless, there is no consensus on a universally accepted treatment. Therefore, additional high-quality studies are needed to identify the most effective therapeutic approaches to achieve better results.

East-West Flap After Mohs Micrographic Surgery. / Colgajo este-oeste después de la cirugía micrográfica de Mohs.

Repair of distal nasal defects resulting from Mohs micrographic surgery is a challenge, but surgeons can choose from a number of techniques. We present 3 cases in which an east-west flap was used to close the defect. The east-west flap is an easily conceived advancement flap that consists of a superior triangle used to cover the defect and an inferior triangle whose base is located along the advancement line. The flap results in an optimal cosmetic outcome and involves minimum movement of tissue (preserving the nasal architecture) and well-camouflaged suture lines.
