one half of the scar will receive standard scar treatment with topical products and pressure garments, but no ablative fractional CO2 laser

The other half of the scar will receive standard scar treatment with topical products and pressure garments and, in addition, will receive ablative fractional CO2 laser treatment

Cicatrix, Hypertrophic

UltraPulse CO2 Laser (Lumenis, Israel). Patients will receive laser treatments at 4 to 8-week intervals for a total of 3 sessions. A combination of the SCAAR FX and Deep FX treatment modes, with or without Active FX treatment mode, will be used according to individual patient and scar characteristics. For SCAAR FX, the settings include energy (70-150mJ), density (1-5%), and frequency (150-250Hz).For Deep FX, the settings include energy (12.5-22.5mJ), density (5-15%) and frequency (300-600Hz). For Active FX, the settings include energy (80-125mJ), density (2-3%) and frequency (100-150Hz)

Review of before and after photographs of scars by blinded observers

University of Calgary

One part of the outcomes will be assessment of clinical photographs of the scars. The assessor will be blinded to which part of the scar received the laser treatment.

Subjects will be recruited in three groups, all of whom are infected with HSV-1, as shown by having IgG against HSV-1:
Group A: 12 subjects with 6 or more herpes labialis outbreaks in the past 12 months.
Subjects in group A will receive 2% Squaric Acid Dibutyl Ester (SADBE) dose on the arm after their initial blood samples are obtained. Group A subjects will have blood collected and tests repeated 2 and 8 weeks later.
Subjects in Groups B and C will be matched to the subjects in Group A so that demographic characteristics (i.e., gender distribution, age and weight) are within broadly similar ranges.

Subjects will be recruited in three groups, all of whom are infected with HSV-1, as shown by having IgG against HSV-1:
Group B: 12 subjects with 1 to 2 outbreaks in the past 12 months. Subjects in Groups B and C will be matched to the subjects in Group A so that demographic characteristics (i.e., gender distribution, age and weight) are within broadly similar ranges. Invite these back for a further blood draw on Day 0.

Subjects will be recruited in three groups, all of whom are infected with HSV-1, as shown by having IgG against HSV-1:
Group C: 12 subjects with zero outbreaks in the past 12 months. Subjects in Groups B and C will be matched to the subjects in Group A so that demographic characteristics (i.e., gender distribution, age and weight) are within broadly similar ranges. Invite these back for a further blood draw on Day 0.

Herpes Labialis

2% squaric acid dibutyl ester (SADBE) (Supplied by Squarex) is topically applied to the inner aspect of the upper arm of the subject and covered with Tegaderm. Subject is advised to wash it off after 3 hours.

Immune Response and General Immune Health in Subjects Infected With Herpes Simplex Virus Type 1 (HSV-1)

A Phase I Study of the Immune Response to Herpes Simplex Virus Type 1 (HSV-1) and General Immune Health in Subjects Infected With HSV-1

Cell Counts (Lymphocyte, T cell, B call, CD4, CD8, natural killer cells counts)

Serum Cytokine Levels ( IL2R, IL12, INFG, IL4, IL5, IL10, IL13, IL1B, IL6, IL8, TNFA, IL2, IL17) in pg/mL

RNA gene expression arrays for 42 cytokine and immune related genes, expressed as ratio of absolute gene expression in PBMCs for each group (A, B, C, those with 0, few, or 6 or more herpes labialis outbreaks in the prior 12 months) on Day 0,1 and 2 and a each test condition (no stimulus, HSV-1, HSV-infected cell extracts, or Candida).

PBMC proliferation in response to 3 stimuli: HSV-1 virus, HSV-1-infected cell extracts, and Candida albicans extract.

Subjects will be recruited in three groups, all of whom are infected with HSV-1, as shown by having IgG against HSV-1:
x Group A: 12 subjects with 6 or more herpes labialis outbreaks in the past 12 months x Group B: 12 subjects with 1 to 2 outbreaks in the past 12 months x Group C: 12 subjects with zero outbreaks in the past 12 months Subjects in group A will receive 2% SADBE dose on the arm after their initial blood samples are obtained. Group A subjects will have blood collected and tests repeated 2 and 8 weeks later.
Subjects in Groups B and C will be matched to the subjects in Group A so that demographic characteristics (i.e., gender distribution, age and weight) are within broadly similar ranges.

Methylene blue compound injection are mixed by Methylene Blue injection, Dexamethasone powder-injection, Ropivacaine injection and Normal saline injection. Each individual component can help in a very wide range of medical conditions without serious side effects.
Every patient received intradermal mixed methylene blue compound injection twice. All patients were observed during the hospitalization at the first injection, and two weeks later they received the second injection at the outpatient department.

Methylene Blue Injection for Nonneoplastic Epithelial Disorders of Vulva

Evaluation of the Efficacy of Mixed Methylene Blue Compound Injection for the Treatment of Nonneoplastic Epithelial Disorders of Vulva.

The patients rate the itching on a visual analogue scale (VAS) before and after the treatment. A VAS is a 100-mm long horizontal line with verbal descriptors at each end to express the extremes of the itching feeling. The most severe itching equals to score 10, and no itching equals to score 0. Patients marked the point on the line that best corresponded to their itching severity.

Doctors rate the hypopigmented skin on a vulva surface area scale (VSAS) before and after treatment through colposcopy. The vulva area is divided into six regions as labia majora, labia minora, interlabial sulci, clitoris and clitoral hood, perineum, and perianal area. The investigators estimated that the area percentage of labia majora, labia minora, interlabial sulci, clitoris and clitoral hood, perineum, and perianal area was 48%, 24%, 4%, 4%, 10% and 10% differently. Among the six regions, interlabial sulci, clitoris and clitoral hood, perineum, and perianal area could be divided into four equal proportions at most when the area percentage was calculated. And each side of labia majora and labia minora could be divided into four equal proportions at most. If all the vulva area is involved, the VSAS score is 100%, and if no area of vulva is involed, the VSAS score is 0%.
