Errichetti E, Ankad BS, Jha AK, Sonthalia S, Akay BN, Bakos R, et al. International Dermoscopy Society criteria for non-neoplastic dermatoses (general dermatology): validation for skin of color through a Delphi expert consensus. International journal of dermatology. 2021. Abstract

BACKGROUND: The International Dermoscopy Society (IDS) recently released a set of five basic dermoscopic parameters (vessels, scales, follicular findings, "other structures," and specific clues) encompassing a total of 31 subitems to standardize the use of dermoscopy in non-neoplastic dermatoses, yet they have been developed taking into account Caucasian/Asian skin, with consequent possible limitations if used in dark skin.

OBJECTIVES: To validate the abovementioned criteria for the use in dark-skinned patients (phototypes IV-VI) through an expert consensus.

METHODS: The two-round Delphi method was adopted, with an iterative process consisting of two rounds of email questionnaires. Potential panelists were recruited via e-mail from all over the world based on their expertise on dermoscopy of non-neoplastic dermatoses in skin of color.

RESULTS: Twenty-two panelists took part in the validation process. All of the five originally proposed parameters and subitems reached agreement during the first round, aside from "follicular red dots." Additionally, during round 1, five new subitems were proposed (perifollicular scales distribution, follicular openings obliteration, broken hairs, eccrine pigmentation, and eccrine ostia obliteration), along with the possibility to change the denomination of parameter 3 (from "follicular findings" to "follicular/eccrine findings") and split it into two subparameters ("follicular findings" and "eccrine findings"). All such proposals reached agreement during the second round and therefore were included in the final list, for a total of 37 items.

CONCLUSIONS: Although nearly all the dermoscopic criteria originally proposed by the IDS are applicable even to darker phototypes, several additional variables need to be assessed.

Errichetti E, Ankad BS, Sonthalia S, Jha AK, Keshavamurthy V, Kyrgidis A, et al. Dermoscopy in general dermatology (non-neoplastic dermatoses) of skin of colour: a comparative retrospective study by the International Dermoscopy Society. European journal of dermatology : EJD. 2020;30(6):688-98. Abstract

BACKGROUND: Dermoscopy has been shown to be a useful supportive tool to assist the diagnosis of several non-neoplastic dermatoses (i.e. inflammatory, infiltrative and infectious skin diseases), yet data on skin of colour is still limited.

OBJECTIVES: To characterize dermoscopic features of non-neoplastic dermatoses in dark-skinned patients in order to identify possible clues that may facilitate the differential diagnosis of clinically similar conditions.

MATERIALS & METHODS: Members of the International Dermoscopy Society were invited to submit cases of any non-neoplastic dermatosis developing in patients with Fitzpatrick Phototypes V-VI whose diagnosis had been confirmed by the corresponding gold standard diagnostic test. A standardized assessment of the dermoscopic images and a comparative analysis according to clinical presentation were performed. Seven clinical categories were identified: (I) papulosquamous dermatoses; (II) facial hyperpigmented dermatoses; (III) extra-facial hyperpigmented dermatoses; (IV) hypopigmented dermatoses; (V) granulomatous dermatoses; (VI) sclerotic dermatoses; and (VII) facial inflammatory dermatoses.

RESULTS: A total of 653 patients (541 and 112 with Phototype V and VI, respectively) were recruited for the analysis. Thirty-six statistically significant dermoscopic features were identified for papulosquamous dermatoses, 24 for facial hyperpigmented disorders, 12 for extra-facial hyperpigmented disorders, 17 for hypopigmented disorders, eight for granulomatous dermatoses, four for sclerotic dermatoses and 17 for facial inflammatory diseases.

CONCLUSION: Our findings suggest that dermoscopy might be a useful tool in assisting the diagnosis of clinically similar non-neoplastic dermatoses in dark phototypes by revealing characteristic clues. Study limitations include the retrospective design, the lack of a direct dermoscopic-histological correlation analysis and the small sample size for less common diseases.

Shalaby SM, Bosseila M, Fawzy MM, Abdel Halim DM, Sayed SS, Allam RS. Fractional carbon dioxide laser versus low-dose UVA-1 phototherapy for treatment of localized scleroderma: a clinical and immunohistochemical randomized controlled study. Lasers Med Sci. 2016;31(8):1707-15. Abstract

Morphea is a rare fibrosing skin disorder that occurs as a result of abnormal homogenized collagen synthesis. Fractional ablative laser resurfacing has been used effectively in scar treatment via abnormal collagen degradation and induction of healthy collagen synthesis. Therefore, fractional ablative laser can provide an effective modality in treatment of morphea. The study aimed at evaluating the efficacy of fractional carbon dioxide laser as a new modality for the treatment of localized scleroderma and to compare its results with the well-established method of UVA-1 phototherapy. Seventeen patients with plaque and linear morphea were included in this parallel intra-individual comparative randomized controlled clinical trial. Each with two comparable morphea lesions that were randomly assigned to either 30 sessions of low-dose (30 J/cm(2)) UVA-1 phototherapy (340-400 nm) or 3 sessions of fractional CO2 laser (10,600 nm-power 25 W). The response to therapy was then evaluated clinically and histopathologically via validated scoring systems. Immunohistochemical analysis of TGF-ß1 and MMP1 was done. Patient satisfaction was also assessed. Wilcoxon signed rank test for paired (matched) samples and Spearman rank correlation equation were used as indicated. Comparing the two groups, there was an obvious improvement with fractional CO2 laser that was superior to that of low-dose UVA-1 phototherapy. Statistically, there was a significant difference in the clinical scores (p = 0.001), collagen homogenization scores (p = 0.012), and patient satisfaction scores (p = 0.001). In conclusion, fractional carbon dioxide laser is a promising treatment modality for cases of localized morphea, with proved efficacy of this treatment on clinical and histopathological levels.

Hoshy KE, Bosseila M, Sharkawy DE, Sobhi R. Can Basal Cell Carcinoma Lateral Border be Determined by Fluorescence Diagnosis? Photodiagnosis and Photodynamic Therapy. 2016. AbstractWebsite

Background
The preferential accumulation of 5-aminolaevulinic acid (ALA)- induced protoporphyrin IX (PpIX) in neoplastic cells supports its potential use in the photodetection of epithelial tumours through porphyrin fluorescence.

Objective
To assess the validity of fluorescence diagnosis (FD) as an efficient pre-surgical in vivo imaging tool for defining the lateral boundaries of various types of basal cell carcinomas (BCCs).

Methods
The BCC tumour area was determined for 27 patients using FD digitalized imaging system, where the accumulation of PpIX in tumour tissue in relation to normal tissue was measured. Subsequently, BCCs were excised according to the complete area defined by FD using Mohs micrographic surgery (MMS).

Results
Of the 27 BCCs, the FD margin of the lesion coincided with the histopathological picture in 12 BCCs (44.44%). The mean value of accumulation factor (AF) was 2.7. Although 17 pigmented BCCs showed attenuated or absent fluorescence in the center, fluorescence at their periphery was used as a guide for excision, and statistically, the pigmentation of the BCCs showed no effect on the results of the FD efficacy (p = 1.0).

Conclusion
Fluorescence diagnosis of BCC may be beneficial as a guide to the safety margin needed before MMS. The safety margin is decided according to the FD tumour diameter in relation to the clinical tumour diameter.

Bosseila M, ElSayed K, El-Din SS, Monaem NA. Evaluation of Angiogenesis in Early Mycosis Fungoides Patients: Dermoscopic and Immunohistochemical Study. Dermatology. 2015;31(1):82-6. Abstractangiogenesis_proofs-dermatology_journal2015.pdfWebsite

BACKGROUND:
Angiogenesis is the production of new blood vessels from an existing vascular network; it plays a critical role in solid tumor development and metastasis.
OBJECTIVES:
To assess angiogenesis in early cases of mycosis fungoides (MF) and to determine vascular patterns in MF dermoscopically.
METHODS:
25 patients with MF and 20 healthy controls were included. The MF lesions were assessed dermoscopically. CD34 immunohistochemistry was performed to count dermal microvessel density (MVD).
RESULTS:
The total dermal MVD was significantly higher in MF patients (19.77 ± 5.81) than in controls (4.44 ± 3.16; p = 0.013). Among them, there were 10.8 ± 4.1 sprouts of endothelial buds (clusters of cells per field) in patients and 2.4 ± 2 in controls (p = 0.000). The dotted pattern of blood vessels was the most frequently encountered pattern in the MF lesions by dermoscopy.
CONCLUSIONS:
Our findings support that neoangiogenesis is significantly increased in early MF lesions and that the main dermoscopic feature of MF is dotted blood vessels.

Hafez VG, Bosseila M, Abdel Halim MR, Shaker OG, Kamal M, Kareem HS. Clinical effects of “pioglitazone”, an insulin sensitizing drug, on psoriasis vulgaris and its co-morbidities, a double blinded randomized controlled trialx1. Journal of Dermatological Treatment. 2014:1-7. AbstractWebsite

OBJECTIVES:
To evaluate the therapeutic efficacy of pioglitazone on psoriasis vulgaris and its comorbidities.
MATERIALS AND METHODS:
Forty-eight patients with moderate-to-severe psoriasis vulgaris were enrolled in this randomized double blinded placebo-controlled trial. Active treatment included: oral pioglitazone 30 mg daily for 10 weeks. Primary outcome (treatment success) was PASI-75. Secondary outcomes included changes in metabolic syndrome, insulin resistance and cardiovascular risk.
RESULTS:
Treatment success was achieved in 5/24 (21%) in the pioglitazone group compared to 1/24 (4%) in the placebo group; however, this difference was not significant (p = 0.081). Compared to placebo, no significant difference existed as regards high-sensitive C reactive protein. Metabolic syndrome and insulin resistance were not affected.
CONCLUSIONS:
This short term (10 weeks duration) study revealed no effect of pioglitazone 30 mg daily neither on the clinical response of moderate-to-severe psoriasis nor on metabolic syndrome and insulin resistance. Cardio-protective role appears to be more related to improvement of psoriasis.
LIMITATION:
Short duration of treatment and small number of subgroups.

Abstract
BACKGROUND:
Monitoring of tumor burden during mycosis fungoides (MF) treatment, is crucial to adjust therapy accordingly. This is usually achieved through combined by clinical assessment with histopathological and immunohistochemical evaluation.
AIM:
To assess the validity of fluorescence diagnosis (FD) in the measurement of response to therapy in early MF, using in comparison flow cytometric technique of skin biopsies for CD4+/CD7- malignant T-cell count before and after therapy.
PATIENTS AND METHODS:
Twenty-two patients of histologically proven early MF (stages Ia, Ib, IIa) were subjected to fluorescence diagnosis of their most affected skin lesion before and after 12 weeks of phototherapy with or without combination therapy. In comparison flow cytometric assessment of skin biopsies for CD4+/CD7- malignant T-cell count was evaluated before and after therapy from skin biopsy of the same lesion.
RESULTS:
All tested MF lesions showed varying degrees of fluorescence by FD at week zero, with a mean accumulation factor (AF), which is the fluorescence ratio between the tumor tissue and normal skin, of 2.2. After 12 weeks of therapy, the mean AF showed significant reduction to 1.94 (p=0.009). The percent of CD4+/CD7- cells dropped significantly after treatment (p=0.029). No correlation between CD4+/CD7- cell counts and the mean AF could be deduced.
CONCLUSION:
In cases of mycosis fungoides, fluorescence diagnosis can represent an effective tool for evaluating the response to therapy. Changes in accumulation factor values can be used for follow-up of therapy in the same patient, but it should not be used as an absolute value.
