Buffalo hump is a manifestation of HIV related lipodistrophy, it is characterized by an enlargment of dorsocervical fat pad and is distressing for patients. Surgical correction until a few years ago was the only option for treatment, however in last years non surgical corrections was carried out with minimally invasive techniques. Authors report this case that describe a longer follow up of an already published study were this deformity was treated with the injection of an adipocitolitic aqueous micro-gelatinous solution and during all the follow up no relapse was observed.

Background: Facial lipoatrophy is one of the most distressing manifestation for HIV patients. It can be stigmatizing, severely affecting quality of life and self-esteem, and it may result in reduced antiretroviral adherence. Several filling techniques have been proposed in facial wasting restoration, with different outcomes. The aim of this study is to present a triangular area that is useful to fill in facial wasting rehabilitation., Methods: Twenty-eight HIV patients rehabilitated for facial wasting were enrolled in this study. Sixteen were rehabilitated with a non-resorbable filler and twelve with structural fat graft harvested from lipohypertrophied areas. A photographic pre-operative and post-operative evaluation was performed by the patients and by two plastic surgeons who were "blinded." The filled area, in both patients rehabilitated with structural fat grafts or non-resorbable filler, was a triangular area of depression identified between the nasolabial fold, the malar arch, and the line that connects these two anatomical landmarks., Results: The cosmetic result was evaluated after three months after the last filling procedure in the non-resorbable filler group and after three months post-surgery in the structural fat graft group. The mean patient satisfaction score was 8.7 as assessed with a visual analogue scale. The mean score for blinded evaluators was 7.6., Conclusion: In this study the authors describe a triangular area of the face, between the nasolabial fold, the malar arch, and the line that connects these two anatomical landmarks, where a good aesthetic facial restoration in HIV patients with facial wasting may be achieved regardless of which filling technique is used.

One limiting factor of hair transplantation is the amount of hair available in the patient donor scalp. Several techniques have been proposed as steel punches, multiblade knives, FUE (follicular unit extract) and single-strip harvesting. The authors introduce a modified surgical scalpel with a No. 10 blade to minimize side effects. This scalpel is folded at 120-degree angle and allows the incision to be parallel to the hair follicles and help the surgeon to avoid resection of the hair during dissection. The authors propose this modified scalpel as a new ideal instrument for removing the donor area in hair transplantation.

Background: Improvement in skin laxity can be difficult to achieve without invasive surgical procedures. Monopolar radiofrequency (RF) treatment is used by physicians to heat skin and promote tissue tightening and contouring. RF technology produces an electric current that generates heat through resistance in the dermis and subcutaneous tissue. The thermal effect depends on the conductivity features of the treated tissue. When heated, collagen fibrils will denature and contract, which is believed to lead to the observed tissue tightening., Methods: Ninety-three consecutive patients with mild to moderate laxity were included in the study. The Surgitron Dual Frequency RF (Radiowave technology, Ellman International) was used to treat skin laxity. The application of RF energy took place in an ambulatory setting with no need for skin sterilization or anesthesia., Results: Patients immediately noticed a microlifting retraction in the treated tissues according to the vectors mapped in the area. There were no significant complications and the majority of patients were satisfied with the procedure and able to return to their daily routine after leaving the office, thereby substantiating the popularity of noninvasive rejuvenating procedures.

Background: Despite their benign nature, keloids may constitute a severe aesthetic and, in some cases, functional problem with important repercussions on patients' quality of life. There is no consensus on keloid treatment and no wholly satisfactory therapy has yet emerged., Objective: To assess the efficacy of cryotherapy in the treatment of keloids., Methods: 135 patients with 166 keloids received cryosurgical treatment between 1990 and 2004. Freeze times and number of sessions varied. Scar volume was measured before and after treatment. Median follow-up was 48.6 months (range 12.4-72.6 months)., Results: Of the 166 lesions treated, 79.5% responded very well with a volume reduction of the initial mass of greater than 80% after a median of 3 treatments (range: 1-9). A good result was obtained in 14.5% of lesions, while results were unsatisfactory in 6% of cases. The main adverse effects reported were atrophic depressed scars and residual hypopigmentation (75% of cases). No recurrences arose during the follow-up period (12-72 months)., Conclusions: To date, cryotherapy appears to be the most effective, safe, economic, and easy-to-perform monotherapy to treat keloid lesions and hypertrophic scars.

Melasma is a common disorder of hyperpigmentation involving sun exposed face and neck areas. Three clinical patterns of melasma are recognized: the centrofacial, the malar, and the mandibular ones. Several factors have been implicated in the pathogenesis of this disorder including pregnancy, oral contraceptive therapy, sun exposure, genetic factors, cosmetics, and race. This condition is most frequently observed in women and affects all racial groups; however, it is commonly found in darker-complexioned individuals (skin types IV through VI) and in Asian women who live and work under strong sunlight exposure for long periods. Melasma is very difficult to treat and often resistant to therapy. Treatment of melasma includes various hypopigmenting agents, chemical peeling, and laser surgery with unsatisfactory results. We report 3 cases of facial melasma successfully treated with a Q-switched Alexandrite laser.

Hyperhidrosis is an invalidating condition, and one that is difficult to treat. It is characterized by an excessive and uncontrolled production of sweat by the sweat glands, often causing psychological, social, and occupational problems for the patient. Hyperhidrosis can be distinguished in two forms: idiopathic (of unknown etiology), or secondary, due to an alteration of the endocrine system (ex: hyperthyroidism, neuropathy, neoplasia etc.) It is found in about 0.3-0.5% of the population and can be localized (axillary, palmar, plantar, facial) or diffused. The subcutaneous injection of type A botulinum toxin, until now used only for the treatment of blepharospasm or hemifacial spasm, has shown to be a useful treatment for localized hyperhidrosis. The objective of the authors is to evaluate the therapeutic efficacy, safety, and management of botulinum toxin treatment in patients affected with axillary or palmar hyperhidrosis resistant to conventional therapies.
