The Effects of Oral Isotretinoin on Atrophic Acne Scars Measured by Shear-wave Elastography: An Observational, Single-center Study.

Background: Although the effects of oral isotretinoin (OI) on acne vulgaris and preventing further acne scars have been well-documented, the specific impact of OI alone on pre-existing atrophic acne scars (AAS) remains unclear. No clinical study has objectively evaluated the effect of OI on AAS yet. Objective: We sought to investigate the OI effect on AAS quantitatively and reliably by shear-wave elastography (SWE). Methods: This work is a single-center, prospective and observational study. Thirty patients with moderate and severe acne vulgaris accompanied by AAS were included. We started the OI with a standard dose regime. On Days 0 and 90 of treatment, patients' global acne grading system (GAGS) and the Goodman and Baron's Qualitative Global Scar Rating System (GSRS) were evaluated. The dermal thickness, subcutaneous tissue thickness, scar size, and scar and subcutaneous tissue's elastic modules were measured on both cheeks of each patient by SWE. Results: The improvement in GSRS stages and GAGS scores in 90 days were statistically significant (respectively; p=0.029, <0.001). Scar size and dermal thickness decreased, while the subcutaneous tissue thickness and the elastic modulus of scar and subcutaneous tissue increased in bilateral cheeks. The thickness changes in the right side dermis, and subcutaneous tissue on both sides were noteworthy (p<0.05). Conclusion: Besides its well-known effect on acne vulgaris, OI also could be an effective treatment option for reducing scar size and severity while improving skin elasticity. SWE may help follow skin and scar properties.

Clinical and Histopathological Evaluation of Forty-one Cases of Pediatric Granuloma Annulare.

INTRODUCTION: Granuloma annulare (GA) is a non-infectious granulomatous disease that can affect children and adults. Although many studies have been conducted in adult GA patients, the literature on pediatric GA cases is limited. OBJECTIVES: Therefore, this study aimed to examine the demographic, clinical, and pathological features of pediatric GA cases. METHODS: This study was performed retrospectively in a single-center tertiary dermatology hospital. Demographic characteristics and clinical and histopathological features were recorded. RESULTS: Forty-one participants were included in this study, of which 66% were females. The mean age was 3.8 ± 2.6 years, and the mean lesion duration was 7.5 ± 10.3 months. The involvement of 78% of the patients was localized, and the remaining 22% was generalized. Asthma (30%) was the most common comorbid disease. Histopathological examination was performed on 21 patients, and the infiltrate pattern was interstitial in 71% of the cases and palisadic in 29%. Generalized distribution, trunk involvement, and concomitant disease tended to be higher in patients with an interstitial pattern than in those with a palisadic pattern. CONCLUSIONS: Atopy and asthma should be questioned in pediatric GA cases. There are differences between involvement, distribution, concomitant disease, and histopathological patterns, which may indicate differences in pathogenesis.

Knowledge levels and concerns about oral isotretinoin treatment in the parents of adolescent acne patients.

Oral isotretinoin is frequently used in the treatment of young acne patients. However, knowledge levels and attitudes about this treatment have not been studied in the parents previously. We aimed to investigate the knowledge levels and concerns about oral isotretinoin in the parents of adolescent acne patients. We conducted a cross-sectional study on 136 parents of adolescent patients with moderate to very severe acne vulgaris who answered the questionnaire about oral isotretinoin treatment. Demographic data and acne characteristics were recorded. The parents' knowledge levels and concerns about the treatment process were asked by the questionnaire. Since 32 parents have never heard oral isotretinoin before, they were excluded from the study. Of the remaining 104 parents, 80.8% were female and 19.2% were male. Of the parents, 62.5% had some concerns about oral isotretinoin treatment and 34.6% had no idea whether the drug is suitable for the use of <18 years. 52.9% stated that they think the drug will damage the liver. The most known and worrying side effects were dry lips and vision problems, respectively. The knowledge levels about oral isotretinoin treatment and its side effects were low in the parents of adolescent acne patients, leading to prejudice to the drug.

Congenital lateral cleft palate with unilateral craniofacial microsomia and lateral ankyloglossia.

Craniofacial microsomia is a group of anomalies that occur due to developmental defects in the first and second branchial arches during the embryological period. The disease has various craniofacial and extracraniofacial presentation patterns. Lateral cleft palate is distinct from the most common palate clefts because it is located lateral to the uvula. The presence of a lateral cleft palate has been very rarely reported in the literature, and the aetiopathogenesis of the disease is still not well understood. We aimed to report a case of the coexistence of lateral cleft palate and craniofacial microsomia and discuss the aetiopathogenesis of these diseases.
