Brief Summary

The wound healing is a process occurring in response to dermal injury. The resulting scar may have various characteristics ranging from fine-line and asymptomatic to hypertrophic scars and keloids. Prevention or early treatment of pathological scars is the most appropriate approach. Among available remedies, gels and patches containing onion extract and allantoin have been demonstrated to be safe and effective in patients with scars of various origins and severity. One of the most used natural products is a patch containing allium cepa and allantoin licensed for treatment of the scars including keloids. However, up to date, no controlled studies have evaluated the effects of such a device in women who have undergone Cesarean delivery. Therefore, the aim of this study was to investigate the effects of this patch on Cesarean section (C-section) scars.

Outcome Measures

Primary Outcomes (1)

  • Effectiveness of an overnight 4-week Treatment with Patch containing Onion Extract and Allantoin for Cesarean Section Scars in women undergone to Cesarean section as assed by POSAS v.2.0.

    The primary outcome was represented by the number of women undergone a Cesarean section (C-section) that used for 4-week a patch containing Allium Cepa extract and allantoin in respect to controls. The Patient and Observer Scar Assessment Scale (POSAS) was used to compare the differences from baseline to 4-week treatment and between controls and subjects using the patch

    Scars were evaluated at baseline and after 4 weeks by two observers and by the subjects.Scars assessment was made using digital photographs and the validate Patient and Observer Scar Assessment Scale (POSAS, version 2.0).

Study Arms (2)

Group A included subjects without a history of C-section

Group A consisted of 47 women without a prior a history of C-section: 24 controls and 23 subjects who used patch. These latest 23 subjects applied overnight a patch containing a standardized quantity of Allium Cepa extract and allantoin on C-section scars over 4 weeks

Device: patch

group B subjects who had already undergone previous C-section

Group B consisted of 46 women already undergone previous C-section: 22 controls and 24 subjects who used patch. These latest 24 subjects applied overnight a patch containing a standardized quantity of Allium Cepa extract and allantoin on C-section scars over 4 weeks

Device: patch

Study Population

The study population was represented by adult women, subdivided in two groups, A and B on the basis of the number of Cesearean delivery. Group A included subjects without a prior history of Cesarean delivery, Group B subjects who had already undergone previous Cesarean delivery. All the women were enrolled at University Hospital of Salerno, were \>=18 years old without hypersensitivity to any constituent of the patch, who have not experienced pre-term birth, obesity, gestational diabetes, hypertension, infections, dermatologic diseases and use of both systemic and topic corticosteroids. All the partecipants were volunteers and released a written informed consent

You may qualify if:

  • subjects undergone Cesarean delivery;
  • age \>18;
  • voluntary participation to the study;
  • informed consent release.

You may not qualify if:

  • age \<18
  • hypersensitivity to any constituent of the patch;
  • pre-term birth, obesity,
  • gestational diabetes,
  • hypertension,
