Intradermal PRP injection in combination with NB-UVB could be considered as a simple, safe, tolerable, and cheap technique for treatment of vitiligo. It shortens the duration of NB-UVB therapy and is expected to increase patient compliance. Longer follow-up is needed.
Striae distensae is a challenging cosmetic problem for which various treatment modalities have been applied. To compare between the efficacy and tolerability of intradermal injection of autologous platelet-rich plasma (PRP) vs. microdermabrasion in the treatment of striae distensae. Sixty-eight patients with striae distensae were randomly assigned to three groups according to therapeutic modalities. Patients of group I were treated by intradermal injection of PRP alone, patients of group II were treated with microdermabrasion alone, and patients of group III were treated with combination of intradermal PRP and microdermabrasion in the same session. Each patient underwent maximum of six sessions at 2-week interval. Skin biopsies were taken from some patients at baseline, and 3 months after the last sessions stained with hematoxylin and eosin stain, Masson trichrome, orceun, and Van Gieson stains to study of histopathological changes and efficacy of treatment. There was significant clinical improvement of striae distensae in patients treated with PRP injection and patients treated with combination of PRP and microdermabrasion when compared with patients treated with microdermabrasion. However, combination of PRP and microdermabrasion in the same session showed better results in short duration. Collagen and elastic fibers were markedly increased in the dermis at the end of treatment sessions. Platelet-rich plasma alone is more effective than microdermabrasion alone in the treatment of striae distensae, but it is better to use the combination of both for more and rapid efficacy. However, each one of them is well tolerated by the patients, safe and cost effective.
Fractional CO laser therapy combined with NB-UVB phototherapy could be used effectively and safely as an alternative modality for the treatment of vitiligo. It shortens the duration of NB-UVB therapy and is expected to increase patient compliance.
Summary
Background
The popularity of dermal fillers has grown rapidly in the last few years for facial rejuvenation. Plasma gel is an autologous gelatinous material that is prepared from the patient's own platelet poor plasma.
Objective
To evaluate the clinical efficacy and safety of plasma gel injection as a dermal filler for facial rejuvenation.
Patients and Methods
The current study was carried out on 52 females presented with facial aging divided into two groups: Group A included 34 females with facial wrinkles, and Group B included 18 females with tear trough deformity. After taking written informed consent, they received two sessions of plasma gel injections at 2‐week interval and followed up monthly for 3 months. They were assessed clinically before treatment sessions and at the end of follow‐up period.
Results
Both studied groups showed immediate significant clinical improvement after plasma gel injection that maintained till the end of follow‐up period. This finding was confirmed by significant reduction in the mean values of Wrinkle Severity Rating Scale (WSRS) in Group A and Tear Trough Rating Scale (TTRS) in group B, and significant improvement of skin homogeneity and texture in both groups. In general, the reported side effects were minimal and transient.
Conclusion
Autologous platelet poor plasma gel injection seems to be a cost‐effective, safe, well‐tolerated, and minimally invasive technique producing significant aesthetic correction of facial wrinkles and tear trough deformity.
Carboxytherapy seems to be a promising therapeutic option for patchy AA and could be helpful as an adjuvant therapy of AGA but more than 6 sessions are required and adjuvants are recommended for maintenance of the results.
