RESUMEN

INTRODUCTION: Mini-invasive therapies based on autologous non-activated Platelet-Rich Plasma (ANA-PRP), Low-Level Laser Therapy (LLL-T), and Micro-Needling Technique (MN-T) used in combining for hair re-growth need to be standardized. OBJECTIVES: The work aims to show in vivo outcomes resulted from retrospective case-series study in which ANA-PRP + MN-T + LLL-T were used in combined in patients affected by Androgenic alopecia. METHODS: 23 patients were treated, of which 13 males were classified in stage I-V by the Norwood-Hamilton scale, and 10 females were classified in stage I-III by the Ludwig scale. Assessment of hair re-growth was evaluated with photography, physician's and patient's global assessment scale, and standardized phototrichograms during a follow-up: T0 - baseline, T1 - 12 weeks, T2 - 23 weeks, T3 - 44 weeks, T4 - 58 weeks. RESULTS: Interesting outcomes represented by a hair density increase of 81 ± 5 hairs/cm2 and 57 ± 7 hairs/cm2 respectively at T1 and T2 compared with baseline (173 ± 5 hairs/cm2 at T1 and 149 ± 9 hairs/cm2 at T2 versus 92 ± 2 hairs/cm2 at baseline) were observed using computerized trichograms. EXPERT OPINION: The main limitation in the autologous regenerative therapies and biotechnologies in hair-regrowth is the extreme variability of PRP products used, in the absence of standardized protocols and widely shared. Appropriate PRP preparations have to be pick after carefully thinking about their bio-molecular specifications and intended indications for use in patients. This approach will aid in matching the optimal PRP product to specific patient factors, leading to improved outcomes and the elucidation of the cost-effectiveness of this treatment. The combined use of biotechnologies as the association of PRP with micro-needling and low-level laser therapy may improve the results in terms of hair count and hair density compared with those obtained by alone PRP. All the procedures must be performed in the full respect of international and local rules. CONCLUSIONS: The effect of the combined use of MN-T, LLL-T, and ANA-PRP has been demonstrated.

RESUMEN

INTRODUCTION: Therapeutic angiogenesis by autologous-peripheral blood mononuclear cells (A-PBMNC) implantation has been shown to be a safe and effective treatment for critical limb ischemia (CLI). We herein report our investigation of the long-term efficacy of implantation of A-PBMNC produced by selective filtration to treat patients with CLI, for which surgical bypass and/or percutaneous transluminal angioplasty are not possible. MATERIALS AND METHODS: This is a prospective, and not a randomized, study based on a treated group who did not respond to conventional therapy (n=43) when implanted with A-PBMNC cells versus a historically matched control group. Patients of both groups were suffering from CLI Fontaine scale IV with chronic ulcers and various accompanying conditions (diabetes, heart disease, kidney failure, etc.). Treated patients were implanted with 12 mL of A-PBMNC, 0.2-0.3 mL for each bolus, collected by selective filtration from 120 mL of peripheral blood in the ischemic area of the limbs. Patients were not mobilized by granulocyte colony-stimulating factor, and the A-PBMNC treatment was repeated for a maximum of three times. RESULTS: The A-PBMNC-treated group showed a statistically significant improvement of limb rescue of 95.3% versus 52.2% of the control group (p<0.001), and the result had been maintained for 2 years. The A-PBMNC group also showed reduction in pain at rest, increased maximum walking distance, and healing of the wound, which led to an overall improvement in the quality of life. Post-treatment radiological studies showed an improvement of vascularization with the formation of new collateral and by histological findings. Within 2 years of follow-up, none of the patients whom we treated showed any major or systemic adverse effects. CONCLUSION: The local injection of A-PBMNC showed striking early and long-term effects together with a favorable safety profile, significantly decreasing the risk of amputation. Our results are comparable with published data obtained by injection of bone marrow mononuclear cells, but with a lot less invasive approach. Moreover the intraoperative selective filtration system we used is fast, safe, not operator dependent, and easy to use in a sterile operating theatre. This system aims to produce fresh A-PBMNC as a valuable treatment option, particularly for those difficult patients who cannot undergo revascularization.

RESUMEN

Clostridial myonecrosis (CM) is a rare, life threatening necrotizing infection of a skeletal muscle caused by Clostridium perfringens in the majority of cases. The diagnosis may be difficult because of few diagnostic and cutaneous signs early in its course. Standard therapy involves surgical debridements of a devitalized tissue and high-dose organism-specific antibiotic therapy. The hyperbaric oxygen has also showed its usefulness in the treatment of these infections. Autograft systems as tissue replacement, based on bioengineered materials, have been demonstrated to be safe and effective treatments for chronic wounds and a suitable physiotherapy is recommended for the recovery of functional impairments of upper extremities. We present a rare case of CM of right upper limb treated with a combination of standard treatments and new techniques.

RESUMEN

BACKGROUND: Cosmetic surgery and medicine are extremely interesting fields for a plastic surgeon. Lasers and lights determine ablation, contraction and regenerating stimulus in skin tissues. The aim of this study is to examine the use of infrared lights in treating facial and body skin laxity. METHODS: Between 2007 and 2011, in the Department of Plastic and Reconstructive Surgery at the Hospital San Camillo-Forlanini, 303 patients were enrolled in the study and underwent laser therapy. The laser operates in wavelength from 1100 to 1800 nm. The treated areas are: face, neck, eyebrows, abdomen, legs and buttocks. RESULTS: We have noticed no systemic complications. A case of a patient with a three days lasting erythema on both lower eyelids caused by laser therapy healed without any pharmacological therapy. Neither hyper- nor hypopigmentation of the skin was found. The satisfaction degree of patients has been: facial, neck and eyebrow lifting "very satisfactory" for 70% of the patients, "satisfactory" for 10%, "unsatisfactory" for 20%; for the other areas it was "very satisfactory" for 40%, "satisfactory" for 20% and "unsatisfactory" for 40%. CONCLUSION: The use of infrared radiation represents a valid alternative to surgical lifting, but cannot replace it. The infrared light technique used has turned out to be useful in contrasting skin laxity of the face and other parts of the body. The absence of scars and surgical risk makes this technique useable for a large number of patients.
