Same But Different: An 18-Month Cross-Sectional Study of Cosmetic Procedures in Patients With Skin Phototype I-III Versus IV-VI in Toronto, Canada.

BACKGROUND: Patients with darker skin phototypes self-report less facial aging than their lighter-skinned counterparts. However, the association of skin phototype with the type of cosmetic procedures received, is yet to be established in a Canadian context. OBJECTIVE: To compare the pattern of nonsurgical cosmetic procedures performed on people with different Fitzpatrick SPTs. MATERIALS AND METHODS: Cross-sectional study of patient encounters from October 2020-April 2022. Charts and photographs were reviewed and analyzed for age, sex, SPT, and procedure type. Participants were stratified by SPT into 2 cohorts: SPT I-III and SPT IV-VI. SPTs were collapsed into groups based on definitions of "skin of color" (SPT IV-VI) in previous literature. RESULTS: We analyzed 350 patients with mean age 43.4, of whom 320 (91%) were female and 30 (9%) were male. The SPT I-III cohort was older (mean age 45 vs 38.5 years, p < .0001) and more frequently underwent neuromodulator injection. The SPT IV-VI cohort more frequently underwent microneedling, platelet-rich plasma, or electrodessication. CONCLUSION: There are distinct patterns of cosmetic procedures performed. The SPT I-III cohort more commonly received procedures to manage facial aging. The SPT IV-VI cohort was younger and more commonly underwent procedures to manage hyperpigmentation.

The free bilamellar autograft (FBA) procedure: A comprehensive case series of an alternative surgical approach to reconstruction of large eyelid defects.

Purpose: The free bilamellar autograft (FBA) procedure involves harvesting a free, full-thickness section of eyelid tissue from one of the patient's healthy eyelids to reconstruct a large defect of the involved eyelid. No vascular augmentation is employed. The purpose of this study was to determine the structural and cosmetic results of this procedure. Methods: A case series was performed, looking at patients who underwent the FBA procedure for large, full-thickness eyelid defects (>50% eyelid length) between 2009 and 2020 at a single oculoplastic surgical centre. Basal cell carcinomas most frequently met criteria for the procedure. OHSN-REB waived ethics approval. All surgeries were performed by one surgeon. A single operation, with surgical steps reported in detail, was completed with follow-up documentation at ideally 1 day, 1 week, 1 month, 3 months, 6 months, and 1 year. The mean follow-up period was 28 months. Results: Thirty-one patients (17 males, 14 females, mean age 78-years-old) were included in the case series. Comorbidities included diabetes and smoking. Most patients had known basal cell carcinomas removed from the upper or lower eyelid. The mean widths of the recipient and donor sites were 18.8 and 11.5 mm, respectively. All 31 FBA surgeries resulted in structurally functional, cosmetically pleasing, and viable eyelids. Six patients developed minor graft dehiscence, 3 developed an ectropion, and 1 developed mild superficial graft necrosis secondary to frostbite, which fully recovered. Three healing phases were identified. Conclusion: This case series adds to the currently sparse data on the free bilamellar autograft procedure. The surgical technique is clearly articulated and illustrated. The FBA procedure is a simple and efficient alternative to current surgical techniques in the reconstruction of full-thickness upper and lower eyelid defects. The FBA provides functional and cosmetic success, despite the absence of an intact blood supply, with decreased operative time and faster recovery.

Usability, Satisfaction, and Usefulness of an Illustrated Eczema Action Plan.

BACKGROUND: An eczema action plan (EAP) is an individualized tool to help caregivers and patients self-manage eczema. While novel illustrated EAPs have been developed and validated, there is limited literature examining the value of EAPs from patient and caregiver perspectives. OBJECTIVES: The objective of this study was to test the usability, satisfaction, and usefulness of our validated EAP from the perspective of patients and caregivers. METHODS: Consecutive patients from the pediatric dermatology clinic of a tertiary children's hospital from July 2016 to July 2017 were offered enrolment in a prospective survey study; informed consent was obtained from participants. The illustrated EAP was explained to the participant by a trained research assistant. Participants were sent electronic postvisit surveys using Likert scale questions via REDCap on EAP usability and satisfaction (9 items) as well as on usefulness (3 items). RESULTS: Of 233 consecutive clinic patients, 192 participants (82%) were enrolled, and 112 (58%; 85 caregivers and 22 patients) completed the postvisit surveys. Characteristics were similar between responders and nonresponders. Overall, participants rated the usability (96%), satisfaction (85%), and usefulness (78%) of the EAP positively. Education level, experience with eczema, previous dermatology consultation, and participant type (caregiver vs patient) did not significantly affect the usability or usefulness ratings. However, caregivers' overall EAP ratings were significantly higher ( P = .02) than the patients'. CONCLUSION: The caregivers and participants demonstrate that the EAP is a useful and highly usable tool. Future research should examine the effectiveness of EAP use on objective atopic dermatitis outcomes using a pragmatic clinical trial design.

Psychological Aspects of Factitious Disorder.

Factitious disorder can present in multiple health care settings, with patients intentionally producing symptoms to assume the sick role. This assumption of the sick role can result in multiple hospitalizations with unnecessary diagnostic workup, as well as invasive diagnostic procedures that can lead to worrisome side effects. Differential diagnoses that should be ruled out include malingering, somatic symptom disorder, and anxiety disorders. For many providers, patients with factitious disorder can be a challenge to treat because the etiology of the disorder remains unclear. There are multiple psychological theories that attempt to explain the motivation and thought process behind the voluntary production of symptoms. Some of these theories have addressed disruptive attachments during childhood, possible intergenerational transfer of the disorder, personal identity conflicts, somatic illness as a form of masochistic activity toward oneself, and intrapsychic conflicts. Confrontation and psychotherapy with a multidisciplinary team has been proposed as a form of treatment. An understanding of the psychological factors associated with factitious disorder can help providers understand the rationale behind the patient's presentation and aid in the formulation of a treatment plan.

A Systematic Review on Oral Isotretinoin Therapy and Clinically Observable Wound Healing in Acne Patients.

The association between isotretinoin and atypical wound healing remains controversial. It is common practice to delay elective procedures for 6 to 24 months after oral isotretinoin therapy. The studies supporting common practices (SCP) recommend extending this period to include the 6 to 24 months preceding treatment. The opposing studies (challenging common practices; CCP) state that the rate of scarring in isotretinoin patients is low and that delaying elective procedures is unnecessary. These practices impact a large number of dermatology patients undergoing acne treatment. This systematic review compiled articles obtained from online databases and examined data from both SCP and CCP studies. The inconsistencies in the reported data and the methodological flaws in the literature preclude any firm conclusions that can resolve the controversy. As such, this review demonstrates that there is insufficient evidence to either corroborate or refute delaying elective procedures in isotretinoin acne patients. Although the recent literature trends toward removing the procedural delay, we advocate for clinicians to consider the research presented in this review in the context of their own clinical experience and each individual patient's situation. The possible negative procedural outcomes must be weighed against the severity of the patient's acne scarring and the psychosocial impact of this scarring on the patient.

A Case of Amoxicillin-Induced Acute Generalized Exanthematous Pustulosis Presenting as Septic Shock.

This case report demonstrates the challenges of diagnosing and managing acute generalized exanthematous pustulosis (AGEP) presenting as septic shock. The disseminated, erythematous, pustular rash is a common feature. However, extensive organ involvement and life-threatening hypotension are unusual. The constellation of signs has not previously been documented following amoxicillin therapy. Toxic epidermal necrolysis (TEN) and toxic shock syndrome (TSS) were considered in addition to AGEP because of the systemic presentation. AGEP was diagnosed following histopathology (TEN was ruled out based on limited necrotic keratinocytes and lack of epidermal necrosis) and a negative antistreptolysin O titer (eliminated TSS). Antibiotic therapy for septic shock was provided before the diagnosis was confirmed as AGEP. Upon confirmation of the AGEP diagnosis, antibiotics were discontinued and a 5-day course of oral prednisone (40 mg/d) was initiated in addition to topical half-strength (0.05%) betamethasone valerate. The patient rapidly improved and was discharged. Outpatient patch testing confirmed amoxicillin as the culprit drug. In conclusion, it is critical to realize that AGEP cannot be ruled out with a septic shock presentation. Recent drug history is critical in recognizing an adverse drug reaction, and patch testing is useful for determining the culpable drug when the diagnosis is AGEP.

Hair pull test: Evidence-based update and revision of guidelines.

BACKGROUND: The hair pull test lacks validation and has unclear pretest guidelines. OBJECTIVE: We sought to quantify normal hair pull test values and elucidate the effect of pretest hair washing and brushing. The impact of hair texture and lifestyle was also examined. METHODS: Participants (n = 181) completed a questionnaire recording demographics, medications, and hair health/history. A single hair pull test (scalp vertex) was performed. RESULTS: The mean number of hairs removed per pull was 0.44 (SD 0.75). There was no significant difference in the mean number of hairs removed regardless of when participants washed (P = .20) or brushed (P = .25) their hair. Hair pull test values were similar between Caucasian-, Asian-, and Afro-textured hair. There was no significant difference in hair pull values between participants taking medications affecting hair loss and participants not taking these medications (P = .33). Tight hairstyles did not influence hair pull test values. LIMITATIONS: Participant hair washing and brushing could not be controlled during the study, but this information was documented and analyzed. CONCLUSION: Normal values for the hair pull test should be reduced to 2 hairs or fewer (97.2% of participants). The current 5-day restriction on pretest hair washing can be reduced and brushing be made permissible.
