The use of poly-lactic acid to improve projection of reconstructed nipple.

PURPOSE: Nipple-areola reconstruction represents an important step for final mammary reconstruction. Many techniques have been described. The drawback is the progressive nipple projection loss with time from 50% to over 70% of the initial projection. In this report, we evaluated the effect of injectable poly-lactic acid (PLLA) to improve projection of reconstructed nipples. RESULTS: We selected 12 patients with a residual nipple projection between 0.1 and 2 mm. The patients were injected locally inside the nipple with 0.5 ml of PLLA (dilution 1:4) every 4 weeks for 4 times. At the study end, patients were satisfied with results. No adverse effects were observed. After one year, an increase of nipple projection ranging from 0.5 to 3.5 mm was obtained with an average increase of 2.3 mm (282%) and this variation was statistically significant (p < 0.0001). CONCLUSION: The use of injectable PLLA is a simple and effective procedure to improve projection of reconstructed nipple.

Neo-phalloplasty with re-innervated latissimus dorsi free flap: a functional study of a novel technique.

Twenty two patients with gender dysphoria underwent neo-phalloplasties using a novel technique. Latissimus dorsi musculocutaneus re-innervated free flap was used to allow voluntary rigidity of the neo-penis. From the first 22 patients, 18 have obtained motoric function of reconstructed penis; the "paradox erection" was obtained. 14 patients came for examination after a follow-up period of mean 26.4 months. We evaluated the motility and shape changes of neo-phallus measuring its different size and dimension during relax and muscle contraction. The range of neo-phallus length in relaxed position was between 7 and 17 cm (mean 12.2 cm), its circumference in the same position had a range between 13 and 20 cm (mean 13.7 cm). All patients were able to contract the muscle with an average length reduction of 3.08 cm and an average circumference enlargement of 4 cm. In this study, the dimensions and motility were quantified demonstrating the neo-phallus function and size changes during sexual intercourse.

An objective evaluation of contraction power of neo-phallus reconstructed with free re-innervated LD in female-to-male transsexuals.

AIMS: Objective evaluation of contraction power of the neo-phallus reconstructed with a novel technique in female-to-male transsexuals. PATIENTS AND METHODS: From December 2001 to September 2005, 22 patients with gender identity disorder underwent neo-phalloplasty with the re-innervated latissimus dorsi free flap. All the patients were subjected to an early rehabilitation protocol of the transferred muscle; the beginning time of neo-phallus voluntary contraction was recorded in 18 patients. 14 patients, who came for examinations, were objectively evaluated for the strength of transplanted muscle contraction in neo-phallus by electromyography and measurement of the maximum weight lifted. RESULTS: 18 patients were able to voluntarily contract the neo-phallus after an average period of 4.11 months. In 14 of them, the average weight lifted was 1129 g. After electromyography, the mean number of positive peaks in the 100 ms period was 31.5; the mean amplitude from 10 highest positive peaks, measured peak-to-peak, was 0.99 mV. DISCUSSION AND CONCLUSION: The advantage of this technique is non-requirement of the prosthesis for sexual activity due to the development of strong voluntary contraction of the neo-phallus. Our findings document objectively the strength of voluntary contraction of the neo-phallus as a consequence of re-innervation of the transferred muscle. Furthermore, data represent useful tool for clinical assessment and comparison.

Unusual case of resistant actinomycosis following facial trauma.

A case of actinomycosis is reported which appeared as a complication of a ski-pole injury of the face. A 16-year-old girl was treated for 10 years for resistant actinomycosis. She took long-term antimicrobial therapies, underwent repeated excisions, hyperbaric oxygen therapy, repeated skin grafting, immunological treatment, and free flap transfer. The conservative antibiotic treatment was complicated by mycosis and pseudomembranous colitis. After the defect healed up, satisfactory contour of the face was restored with additional free flap transfer. The patient has also been satisfied with the final aesthetic result. The authors highlight the importance of early diagnosis and proper antimicrobial treatment in combination with surgical excisions of granulation tissue preserving vital structures.

The control of epidermal stem cells (holoclones) in the treatment of massive full-thickness burns with autologous keratinocytes cultured on fibrin.

BACKGROUND: Cell therapy is an emerging therapeutic strategy aimed at replacing or repairing severely damaged tissues with cultured cells. Epidermal regeneration obtained with autologous cultured keratinocytes (cultured autografts) can be life-saving for patients suffering from massive full-thickness burns. However, the widespread use of cultured autografts has been hampered by poor clinical results that have been consistently reported by different burn units, even when cells were applied on properly prepared wound beds. This might arise from the depletion of epidermal stem cells (holoclones) in culture. Depletion of holoclones can occur because of (i) incorrect culture conditions, (ii) environmental damage of the exposed basal layer of cultured grafts, or (iii) use of new substrates or culture technologies not pretested for holoclone preservation. The aim of this study was to show that, if new keratinocyte culture technologies and/or "delivery systems" are proposed, a careful evaluation of epidermal stem cell preservation is essential for the clinical performance of this life-saving technology. METHODS: Fibrin was chosen as a potential substrate for keratinocyte cultivation. Stem cells were monitored by clonal analysis using the culture system originally described by Rheinwald and Green as a reference. Massive full-thickness burns were treated with the composite allodermis/cultured autograft technique. RESULTS: We show that: (i) the relative percentage of holoclones, meroclones, and paraclones is maintained when keratinocytes are cultivated on fibrin, proving that fibrin does not induce clonal conversion and consequent loss of epidermal stem cells; (ii) the clonogenic ability, growth rate, and long-term proliferative potential are not affected by the new culture system; (iii) when fibrin-cultured autografts bearing stem cells are applied on massive full-thickness burns, the "take" of keratinocytes is high, reproducible, and permanent; and (iv) fibrin allows a significant reduction of the cost of cultured autografts and eliminates problems related to their handling and transportation. CONCLUSION: Our data demonstrate that: (i) cultured autografts bearing stem cells can indeed rapidly and permanently cover a large body surface; and (ii) fibrin is a suitable substrate for keratinocyte cultivation and transplantation. These data lend strength to the concept that the success of cell therapy at a clinical level requires cultivation and transplantation of stem cells. We therefore suggest that the proposal of a culture system aimed at the replacement of any severely damaged self-renewing tissue should be preceded by a careful evaluation of its stem cell population.

Increased burn patient survival with once-a-day high dose teicoplanin and netilmicin. An Italian multicenter study.

This is the final report of a large, controlled, multicenter Italian study on immuno- and chemotherapy in adult patients with burns affecting 20 to 95% of total body surface area (mean 35%). The antibiotic treatment of burn patients consisted of topical silver sulfadiazine, short-term antimicrobial chemoprophylaxis with pefloxacin (800 mg i.v. qd) for the first 4 days and polychemotherapy with teicoplanin (800 mg i.v. qd) together with netilmicin (300 mg i.m. qd) in one or more cycles of 5-12 days. At random, half of the patients received thymostimulin, 70 mg i.m. qd for the first month and every other day thereafter. The analysis at completion of 634 valid cases showed that when the results are stratified by means of the Roi risk index, 396 of the 530 patients who contracted wound infection (84%) after chemoprophylaxis were in the first three categories and a mean of 95% survived. Of the remaining 134 patients (Roi index 4-5) only 50% survived. There was no difference in survival of the immunotherapy group in comparison with the parallel group without thymostimulin. The short-term antimicrobial prophylaxis prevented wound infection in only 104 of 634 patients (16%) and they were at low risk (84% Roi index 1). Of the bacterial pathogens involved in septic complications Staphylococcus aureus and Pseudomonas aeruginosa were prevalent (86%): eradication was achieved in 43% of patients and clinical cure or improvement were seen with combination chemotherapy in 64% of all patients, mainly with only one treatment cycle. This value increased to 79% for the 395 protocol-complying patients and went down to 20% in the 135 non-compliers. The total survival of complier and non-complier patients was 447 of the 530 valid patients (84%). The overall mortality of the 634 evaluable patients was 13.1%, ranging from less than 2% to 68%. Burn mortality was directly proportional to the percentage of burned body surface area, to increasing age and other variables of the Roi index, a 50% mortality being associated with a 72.5% total body surface area burned. Normoergic burn patients had a mortality rate of 9.1% versus 35.7% in anergic patients.

[Experience with cadexomer iodine (Iodosorb) in the treatment of skin ulcers]. / Esperienze con cadexomero iodico (Iodosorb) nel trattamento delle ulcerazioni cutanee.

Ten patients with cutaneous ulcers were treated with cadexomer iodine, powder and ointment. Cadexomer iodine was evaluated as reduction of ulcers area, pain, removal of pus and debris, exudate, stimulation to granulation, biohumoral tests and side effects. Cadexomer iodine was resulted, as ointment like as powder, a very efficacious drug for the treatment of cutaneous ulcers.
