COVID-19

A large-scale survey of AAD members indicated that use of TELEDERMATOLOGY among respondents went from 14.1% pre-pandemic to 96.9% during the pandemic. Live interactive was the most common modality, although survey respondents felt the combination of video with store-and-forward photographs was the most accurate. Over 80% felt that inadequate reimbursement was the single greatest barrier to use and continuation of teledermatology. Nonetheless, 58% definitely plan to continue utilizing teledermatology.

A recent study involving the sera collected from individuals who were 2 or 4 weeks after their second PFIZER COVID-19 VACCINATION showed neutralization capacity against a number of the newer COVID-19 viral variants, including several from India.

PEDIATRIC DERMATOLOGY

An Italian study showed that, among pediatric patients with Type 1 diabetes, there was about an 8% prevalence of PSORIASIS. This is 4 times the prevalence of psoriasis in the general Italian pediatric population. An etiologic link might be the elevated levels of IL-17 found in Type 1 diabetic serum, as the TH17 pathway is well known to be intimately involved with psoriasis. (Editor’s note: This needs to be repeated in other countries.)

Analysis of 2074 children aged 2-17 who had completed 10 years of participation in the Pediatric Eczema Elective Registry disclosed that those with more severe ATOPIC DERMATITIS were more likely to be diagnosed with a learning disability, independent

of socioeconomic factors. This suggests that children with more severe atopy should be monitored and screened for learning difficulties so that appropriate interventions can be instituted.

PSORIASIS

Using several large insurance databases, including over 123,00 psoriasis or psoriatic arthritis patients, investigators concluded that treatment with USTEKINUMAB was associated with a 1.4-3.0 times lowered risk of hospitalization due to serious infection when compared to other biologic agents and apremilast. Apart from ustekinumab, other drugs received by patient in this study included the following: adalimumab, apremilast, certolizumab, etanercept, golimumab, ixekizumab, and secukinumab.

ATOPIC DERMATITIS/ECZEMA

______________________________________________________________________________________________________________________________

Two cases of RECALCITRANT DYSHIDROTIC ECZEMA were successfully managed with dupilumab 300mg every other week. This adds to the growing body of literature endorsing the use of this biologic drug in this particular off-label manner.

Studies evaluating Investigator Global Assessment, improvement in EASI score, and reduction of itch showed major benefit with both 2mg and 4mg daily doses of the selective JAK INHIBITOR BARICITANIB. Benefit persisted 32-68 weeks into the studies.

HAIR AND NAILS

______________________________________________________________________________________________________________________________

There is an art to taking a history and doing an appropriate examination when dealing with HAIR LOSS in those with tightly coiled hair. The Editor suggests carefully reading through this short, pearl-filled manuscript: Grayson C and Heath C. An approach to examining tightly coiled hair among patients with hair loss in race-discordant patient-physician interactions. JAMA Dermatol. 2021;157(5):505-506.

Aside from hairstyle modification, all of the following—alone or in combination— may be beneficial in the treatment of traction-induced alopecia: topical steroids, topical minoxidil (5% recommended), topical 1% clindamycin, intralesional triamcinolone (2.5-5.0mg/ml dilution), oral tetracycline derivatives (tapered to sub-antimicrobial doses), and hair transplantation.

CUTANEOUS ONCOLOGY, SURGERY, AND LASERS

_____________________________________________________________________________________________________________________________

A decade-long Kaiser Permanente cohort study included over 220,000 adult patients with and without ACTINIC KERATOSIS within 2 years of study initiation. The risk of development of cutaneous squamous cell carcinoma (cSCC) increased each year, but at a faster rate in those with actinic keratosis. At 10 years, the cumulative incidence of cSCC was 17.1% in AK patients compared to 5.7% in control patients.

The cumulative incidence of cSCC was 17.1% 5.7% in ak patients in control patients

Other specific factors associated with cSCC development included older age, Caucasian race, and male gender.

Surgical excision remains the treatment of choice for IN-TRANSIT METASTATIC MALIGNANT MELANOMA. However, multiple or widespread lesions may preclude this approach. The authors successfully managed such a case with the following combination: deep shave removal, followed by electrodesiccation and curettage, followed by 3 months daily application of 5% imiquimod cream.

Wide local excision of EXTRAMAMMARY PAGET’S DISEASE is associated with 20-60% recurrence rates. Mohs micrographic surgery reduces that recurrence rate dramatically (approximately 3.3%) when utilized with intraoperative CK7 staining. The latter allows for identification of atypical subclinical finger-like tumor extension, which might otherwise be missed.

COMMON CUTANEOUS MALIGNANCIES may pose a logistical problem in the oldest of old patients. In a study of 61 patients aged 92-104, electrochemotherapy with bleomycin (under regional or local anesthesia) provided complete response in about 60% and local control over a year in about 80%.

A case of MULTICENTRIC RETICULOHISTIOCYTOSIS demonstrated remarkable response to treatment with the JAK-1 inhibitor, upadacitinib, following failure of prednisone, hydroxychloroquine, methotrexate, and infliximab.

HIDRADENITIS SUPPURATIVA

______________________________________________________________________________________________________________________________

While absenteeism is a known concomitant of active hidradenitis suppurativa (HS), DECREASED PRODUCTIVITY WHILE AT WORK has not previously been explored. This study, involving 523 working HS patients, indicated that about 20% were considerably less productive compared to a time when they were working without active HS. Factors that were associated with reduced productivity included the following: inguinal and gluteal disease, more severe disease, greater pain, and higher rates of anxiety or depression.

ACNE

Due to its ability to reduce cytokine synthesis and release, modest antibacterial properties, and ability to suppress habitual behaviors (such as picking), N-ACETYLCYSTEINE may be beneficial in some cases of acne vulgaris.

Post-hoc analysis of pivotal trial data indicate that SARECYCLINE (1.5mg/kg/day for 12 weeks) showed IGA efficacy rates for truncal acne (chest and back) significantly better than placebo. This parallels the benefit previously reported for facial acne.

Using information from a 2-year sample of the U.S. nationwide Optum Database, the authors found the annualized incidence and prevalence of GRANULOMA ANNULARE to be 0.04% and 0.06%, respectively. These are relatively low incidence and prevalence estimates. Women outnumbered men by a 3-to-1 ratio.
