Introduction: Pincer nails are characterized by an over-curvature of the nail in the transverse axis, causing the pinching of the nail bed at its distal portion. It most commonly affects the toes, occurring rarely in the fingers. Objective: To demonstrate the Fanti's technique for the treatment of pincer nails. Methods: Eleven patients from the Hair and Nails Ambulatory, bearing pincer nails, underwent surgery for the correction of the condition with the Fanti's technique. Results: All patients had complete clinical improvement during the 14-month follow-up period. Conclusions: The present study demonstrates the Fanti's surgical technique for the correction of pincer nails, where anatomical and functional improvement of the operated nails could be observed.

Introduction: The use of botulinum toxin in the periorbital muscles is aimed at reducing expression lines in that site, correcting the eyebrows' height and treating blepharospasm. However, the application of botulinum toxin in this area can lead to undesirable side effects, such as ptosis, edema in the lower eyelids, artificial appearance of the demarcation area between the orbicularis muscle's treated area and the malar region, ectropion and hematomas.
Objective: To treat the dynamic wrinkles in the lower portion of the orbicularis oculi muscle through injections of microdoses of botulinum toxin.
Methods: A prospective monocentric study with the analytical longitudinal observation of 300 patients undergoing treatment with botulinum toxin microdoses in the lower eyelids' rhytids was carried out. Sociodemographic data, patient satisfaction, dose quantification and complications were analyzed.
Results: Sixty-six percent of the patients showed a total improvement of the wrinkles after the first session. The other required an additional session. Eighty-six percent preferred the treatment with this therapeutic modality.
Conclusions: Despite the great benefit offered by the classic injection points for the treatment of periorbital rhytids types I to III, the authors observed the need to treat rhytids type B (presence of wrinkles on the lower eyelid). Due to the high rate of complications in this region, microdoses of botulinum toxin were proven to be effective and safe.

Introduction: Hyperhidrosis is a common disease characterized by excessive sweating. Several treatment options are described as axillary liposuction and laserlipolysis.
Objective: To compare the effectiveness of two treatment methods for axillary hyperhidrosis – one exclusively surgical (liposuction) and the other employing invasive laser therapy (laserlipolysis) – using a prospective, comparative study with a one-year follow up.
Methods: Liposuction was carried out in the right axilla, while laser lipolysis was performed in the left axilla. The evaluation was conducted using the starch-iodine test, comparative histological analysis and patient self-assessment questionnaires.
Results: Twelve patients took part in the study. The starch-iodine test indicated decreased sweating in all patients within one year after the procedures, while the histological analyses showed absence or reduction of the secreting ducts and acini on both sides and in all cases. After one year of follow-up, the patient's satisfaction index measured by the questionnaires remained positive in all cases, with 75% asserting maximum satisfaction, and 25% reporting difference between the sides (better results were described in the right hand side axilla).
Conclusions: Both techniques showed similar effectiveness after one year of follow-up. Laserlipolysis had a lower frequency of postoperative complications.

Introduction: Tuberous sclerosis is a dominant autosomal genodermatosis, classically characterized by facial angiofibromas, fibrotic plaques, periungual fibromas, leaf-shaped hypochromic maculae and fibrous frontal plaques.
Case report: A patient bore this disease, with Koenen tumors in all nail beds of hands and feet, which were resistant to the conventional treatment — simple excision and electrosurgery. Amputation of the nail beds was performed followed by reconstruction with full thickness skin grafts.
Conclusion: The amputation of the nail apparatus and reconstruction with full thickness skin grafts in aggressive, recurrent or high morbidity cases can be an effective therapeutic option.
