Prevalence of adverse events varies with the different oral isotretinoin brands in acne treatment: a retrospective observational study.

Oral isotretinoin remains the most effective treatment for acne. The aim of this retrospective single-center cohort study was to estimate the prevalence of adverse events with the different oral isotretinoin brands used in acne treatment. The population consisted of all patients who consulted for acne between January 2015 and January 2020. The inclusion criterion was the initiation of treatment with oral isotretinoin. The exclusion criteria were the use of two or more brands during the same course of treatment and previous treatment with oral isotretinoin. Statistical analysis was carried out using Chi-square and Mann-Whitney tests. We analyzed 468 patients of whom 68.6% were female. The median age was 21 years. The median weight was 65 kg. The treatment was Roaccutane®, Curacné®, Acnotren®, Isosupra®, Contracné®, or Acnogen® in 44.2%, 28%, 14.5%, 10.5%, 1.7% and 0.4% of cases, respectively. Xerosis was the most frequently reported side effect regardless of the brand. The highest frequencies of hypercholesterolemia (25.6%) and eczema (13%) were noted with Roaccutane®; hypertriglyceridemia (16.8%), epistaxis (9.9%) and fatigue (3.1%) with Curacné®; excessive sweating (4.1%) and headache (4.1%) with Isosupra®; and abnormal liver function tests (11%) with Acnotren®. We found a significant correlation mainly between abnormal ASAT and Acnotren® (p = 0.009), hypercholesterolemia and Roaccutane® [OR = 1.652 (95% CI 1.056-2.585)], hypertriglyceridemia and higher body weight (p = 0.004). Factors related to the drug brand and to characteristics of acne patients could explain the variability in the prevalence of some adverse events.

Clinical and pathological features associated with high-risk, multiple, and recurrent basal cell carcinomas: a retrospective cohort analysis from the Levantine coast of the Mediterranean Sea.

Basal cell carcinoma (BCC) data coming from the Levantine coast of the Mediterranean Sea are limited. The study aimed to primarily analyze the demographic, clinical, pathological, and prognostic characteristics of BCC in this region of the world and secondarily identify features associated with high-risk, recurrent, or multiple BCCs. Patients with at least one diagnosis of BCC registered in the pathology department between January 2015 and December 2019 were included in this analytical retrospective single-center cohort study. Patients with basal cell nevus syndrome were excluded. Patients' characteristics and pathological features were collected through file check for a first analysis. Risk factors and evolution were sought through a phone call interview for the second analysis. The first analysis included 506 BCCs corresponding to 365 patients with a mean age of 65 ± 15 years, twenty-two (6%) were less than 40 years old, 180 (49.3%) were women, and 85 (23.3%) had two or more BCCs. The second analysis included 279 BCCs corresponding to 205 patients. Periorificial and infiltrative BCCs were more frequent in men. Periorificial tumors were more frequently nodular or infiltrative and were associated with recurrence. Tumors with perineural involvement were histologically never nodular nor superficial. Recurrence was more frequent in BCCs having periorificial location, a size larger than 2 cm, or an infiltrative subtype. Multiple BCCs were more frequent in patients with light skin type or familial history of skin cancer. High-risk BCCs were more common in patients with low sun exposure.

Beneficial UVB phototherapy preceding a fractional CO2 laser-UVB protocol in refractory non-segmental vitiligo.

OBJECTIVES: To explore the short- and long-term effects of UVB phototherapy preceding a fractional CO2 laser-UVB protocol in patients with resistant nonsegmental vitiligo. MATERIALS AND METHODS: This single-center, prospective, split-face/body, evaluator-blinded study included adult patients with stable vitiligo refractory to conventional treatments. Two symmetrical lesions were selected. Phototherapy was delivered with one side covered, until minimal erythema. Within 3 days, 31-month-apart sessions of laser were performed on both sides. After each laser session, phototherapy was resumed three times weekly, with all lesions uncovered, until 8 weeks after the last laser session. At baseline, at the end of treatment, and 5 years later, a Mean Improvement Score by Physician (MISP) and a patient satisfaction 10-point visual analog score (VAS) were recorded. RESULTS: Ten patients (8 women and 2 men) were included; their mean age was 32.9 years; phototype III was predominant; the mean duration of vitiligo was 3 years. At the end of treatment and 5 years later, scores of lesions treated with UVB-CO2 -UVB (mean MISP 3.0 and 2.9, mean ΔVAS 4.5 and 3.9, respectively), were higher than those of lesions treated only with CO2 -UVB (mean MISP 2.5 and 2.4, mean ΔVAS 4.1 and 3.6, respectively). After 5 years, one patient lost his partial response and two patients developed light hyperpigmentation on both sides. CONCLUSION: Exposure to UVB before CO2 -UVB explains the higher scores as it was the only variable between the two sides. It may improve the response of resistant lesions with a constantly sustained result over 5 years.

Exploring hTERT promoter methylation in cutaneous T-cell lymphomas.

Cutaneous T-cell lymphomas (CTCLs) are telomerase-positive tumors expressing hTERT, although neither gene rearrangement/amplification nor promoter hotspot mutations could explain the hTERT re-expression. As the hTERT promoter is rich in CpG, we investigated the contribution of epigenetic mechanisms in its re-expression. We analyzed hTERT promoter methylation status in CTCL cells compared with healthy cells. Gene-specific methylation analyses revealed a common methylation pattern exclusively in tumor cells. This methylation pattern encompassed a hypermethylated distal region from -650 to -150 bp and a hypomethylated proximal region from -150 to +150 bp. Interestingly, the hypermethylated region matches with the recently named TERT hypermethylated oncogenic region (THOR). THOR has been associated with telomerase reactivation in many cancers, but it has so far not been reported in cutaneous lymphomas. Additionally, we assessed the effect of THOR on two histone deacetylase inhibitors (HDACi), romidepsin and vorinostat, both approved for CTCL treatment and a DNA methyltransferase inhibitor (DNMTi) 5-azacytidine, unapproved for CTCL. Contrary to our expectations, the findings reported herein revealed that THOR methylation is relatively stable under these epigenetic drugs' pressure, whereas these drugs reduced the hTERT gene expression.

Pediatric lichen planus: a systematic review of 985 published cases.

BACKGROUND: Lichen planus (LP) is a chronic inflammatory disorder usually occurring in middle-aged adults. Data are scarce in the pediatric population. OBJECTIVE: To describe the patients' characteristics, clinical presentation, and management of pediatric LP. METHODS: A systematic literature review of pediatric LP was performed in the Medline and Cochrane databases up to February 1, 2020. Demographic and clinical data were extracted for analysis, in addition to laboratory and histology findings, treatments used, and response to treatment. LP pemphigoides (LPP) was further pooled for a subcategory analysis. RESULTS: One hundred and sixty-four articles were included representing 985 patients. The most common country of origin was India. The most common clinical signs were flat-topped papules (51%); the linear variant was present in 9%. Oral involvement was present in 22%. The most commonly used treatment was topical corticosteroids followed by systemic corticosteroids. The mean duration of treatment was 124.4 days. LPP patients had a short disease duration before diagnosis (4.1 months, P < 0.001) and failed previous treatment more frequently (P < 0.001). Systemic corticosteroids were more often prescribed in this subgroup (75%, P < 0.001) with more recurrence after treatment (31%, P = 0.048). LIMITATIONS: Lack of randomized controlled studies, in addition to publication bias. CONCLUSION: In children, LP had a wide polymorphous clinical presentation, and the reported cases were mostly from India. The linear variant was more common and the oral mucosa was less affected in children. LPP, a rare subtype in children, was treated with systemic corticosteroids and recurred more frequently.

Targeting Epigenetic Modifiers Can Reduce the Clonogenic Capacities of Sézary Cells.

Sézary syndrome (SS) is an aggressive leukemic variant of cutaneous T-cell lymphomas (CTCL) in which the human Telomerase Reverse Transcriptase (hTERT) gene is re-expressed. Current available treatments do not provide long-term response. We previously reported that Histone deacetylase inhibitors (HDACi, romidespin and vorinostat) and a DNA methyltransferase inhibitor (DNMTi, 5-azacytidine) can reduce hTERT expression without altering the methylation level of hTERT promoter. Romidepsin and vorinostat are approved for CTCL treatment, while 5-azacytidine is approved for the treatment of several hematological disorders, but not for CTCL. Here, using the soft agar assay, we analyzed the functional effect of the aforementioned epidrugs on the clonogenic capacities of Sézary cells. Our data revealed that, besides hTERT downregulation, epidrugs' pressure reduced the proliferative and the tumor formation capacities in Sézary cells in vitro.

The impact of acne treatment on quality of life and self-esteem: A prospective cohort study from Lebanon.

BACKGROUND: Acne is highly prevalent among teenagers and young adults, with proven negative psychological and emotional impact. To our knowledge, no study has been conducted to quantify the repercussions of acne on quality of life (QoL) and self-esteem in Lebanon. OBJECTIVE: This study aimed to highlight the effect of acne treatment on QoL and self-esteem of Lebanese adolescents and young adults. METHODS: In this observational prospective study, patients between 15 and 40 years old with moderate-to-severe acne were allocated to one of two treatment groups (isotretinoin vs. systemic antibiotics combined with topical treatments) and followed for a period of 6 months. The effect of acne on QoL was measured using the Dermatology Life Quality Index, Cardiff Acne Disability Index, and Rosenberg Self-esteem Scale before treatment initiation (T1), after 3 months (T2), and after 6 months (T3). A multivariate analysis of covariance model was used. RESULTS: Sixty-two patients were included, of whom 79% were female and 61.3% had moderate acne. Fifty-five percent of patients were treated with systemic antibiotics combined with topical treatments, and 45% received isotretinoin. Mean scores of Cardiff Acne Disability Index, Dermatology Life Quality Index, and Rosenberg Self-esteem Scale at T1 were comparable between the two groups. A significant improvement was noticed in both groups at T2 and T3. The multivariate analysis of covariance model showed an interaction of time and age that concerned 25- to 40-year-old patients in both groups, who were the most negatively affected by acne at T1 and improved the most at T3. CONCLUSION: This study demonstrated the equivalence between acne treatments in improving QoL and revealed the social obstacle that acne creates and its recrudescence in the subgroup of women of childbearing age.

Immune checkpoint inhibitors for advanced or metastatic basal cell carcinoma: how much evidence do we need?

Basal cell carcinoma (BCC) is one of the most frequent and most curable tumors at its early stages. BCC rarely metastasizes and its treatment in this setting is still challenging. Hedgehog inhibitors showed an activity in advanced or metastatic disease. However, there is an unmet need for new agents. Immune checkpoint inhibitors have been assessed in melanoma and other cutaneous tumors, and very recently an anti-PD1 was approved for advanced BCC. In this paper, available data are reviewed on experimental and preclinical studies evaluating immunotherapy in BCC, as well as on the clinical evidence supporting the efficacy and safety of immune checkpoint inhibitors for advanced or metastatic BCC based on case reports, case series and clinical trials.

Severe Granulomatous Rosacea with Cutaneous Lupus Erythematosus.

Rosacea and cutaneous lupus erythematosus (CLE) are chronic inflammatory dermatoses. To our knowledge, no cases of granulomatous rosacea (GR) associated with CLE have been previously reported in the literature. We describe the case of a 38-year-old female patient who presented to our clinic with a diffuse scaly facial erythema, with the codiagnoses of GR and CLE later confirmed with clinicopathological correlation.

Molecular profiling of basal cell carcinomas in young patients.

BACKGROUND: Basal cell carcinoma (BCC) represents by far the most common non-melanoma skin cancer (NMSC) in the world with an increasing incidence of 3% to 10% per year, especially in patients under the age of 40. While variants in the sonic Hedgehog and cell cycle regulation pathways account for the majority of BCC cases in adults, the molecular etiology of BCC in young patients is unelucidated yet. This study aims to investigate the molecular profile of BCC in the young population. METHODS: 28 tumors belonging to 25 Lebanese patients under the age of 40, presenting different stages of BCC and diagnosed at Hôtel Dieu de France-Saint Joseph University Medical Center were included in this study. A selected panel of 150 genes involved in cancer was analyzed by Next Generation Sequencing (NGS) in the 28 included tumors. RESULTS: Genetic variants detected in more than 5% of the reads, with a sequencing depth ≥ 50x, were selected. Two hundred and two genetic variants in 48 different genes were detected, with an overall average sequencing depth of 1069x. Among the 28 studied tumors, 18 (64.3%) show variations in the PTCH1 gene, 6 (21.4%) in TP53 and 3 (10.7%) in SMO. CONCLUSIONS: This is the first study reporting NGS-based analysis of BCC in a cohort of young patients. Our results highlight the involvement of the hedgehog and cell cycle regulation pathways in the genesis of BCC in the general population. The inclusion of a larger cohort of young patients is needed to confirm our findings.

A case of recurrent vaccine-triggered Gianotti-Crosti syndrome.

Gianotti-Crosti syndrome (GCS) is a self-limited benign dermatosis, clinically characterized by a monomorphic papular or papulovesicular eruption symmetrically distributed on the limbs and face of children. Various viral and vaccine triggers have been associated with GCS. Recurrences are uncommon but have been reported. We report a case of recurrent vaccine-triggered GCS.

Eccentric training effects for patients with post-stroke hemiparesis on strength and speed gait: A randomized controlled trial.

BACKGROUND: In hemiparetic patients, the skeletal muscle is mainly affected with a combination of abnormalities (denervation, remodeling, spasticity, and eventually muscular atrophy). OBJECTIVE: This study examined the role of eccentric exercise in strengthening muscles of the lower extremity and ultimately improving autonomy in patients with post-stroke hemiparesis during gait. METHODS: Thirty-seven patients hemiparetic adults were recruited, randomized into a control group (n = 19) and an intervention group receiving eccentric muscle strengthening (n = 18). The protocol consisted of three sets of five repetitions of eccentric contraction of the paretic limb after determining the maximum repetition (1 MRI). Evaluation of the 1RM, 10 meters and 6WMT was performed before and after the exercise for each group. Manova test was used to compare the differences between the control and intervention groups. RESULTS: The paretic limb showed significant increase in one-repetition maximum (1RM) between before and after rehabilitation (p≤0.00003). The two groups of Patients increased their walking speed (p≤0.0005), but we observed a significant difference between groups only for the 6MWT and not on the 10 meters Test. CONCLUSIONS: Eccentric training can be useful in strengthening the muscles of the lower limbs, and promoting gait performance. Eccentric training could complement other methods of managing patients with post-stroke hemiparesis.

Prevalence of STIs, sexual practices and substance use among 2083 sexually active unmarried women in Lebanon.

Access to sexual and reproductive health in conservative communities and in the MENA region are particularly limited and, as such, increase women's vulnerability to unwanted pregnancies, unsafe abortions, and sexually transmitted infections (STIs). The aim was to assess the prevalence of STIs, sexual practices, recreational drug-use and their possible associations among cisgender unmarried women residing in Lebanon. Data on demographics, sexual practices and substance-use were collected from 2083 unmarried cisgender women who voluntarily attended a sexual health clinic in Lebanon between 2015 and 2019. They tested for HIV, Hepatitis B, Hepatitis C and Syphilis through rapid testing. Other infections (genital warts, Neisseria gonorrhea/Chlamydia trachomatis) were screened for. Regression models were computed between variables. There were two cases of HIV, one of Hepatitis B and syphilis, and no cases of Hepatitis C. Genital warts were present in 15% and symptoms indicative of Neisseria gonorrhea/Chlamydia trachomatis in 14%. Inconsistent condom-use (81%) was significantly associated with number of partners (adj. OR: 0.4). Inconsistent condom-use discussion with partners (33%) was significantly associated with unemployment (adj OR: 1.7), recreational drug-use (adj. OR: 1.4), and number of partners (adj. ORs 3.7-4.4). Unwanted pregnancies (11%) were significantly associated with age (adj. ORs 0.1-0.37), recreational drug-use (adj. OR: 2), using intrauterine device (adj. OR:2.9) and natural birth control methods (adj. OR: 2.4). Recreational drug-use (33%) was significantly associated with age (adj ORs 1.9-2.2), and smoking status (adj. OR: 0.6). The results indicate an urgent need for: (1) Accessible, non-stigmatizing, and inclusive sexual health services dedicated to women's sexual health; (2) Comprehensive and non-stigmatizing sexual health education for all, but especially women, in order to promote safer sexual practices and effective decision making with regards to contraception and condom-use.

The place of 5-aminolaevulinic acid-photodynamic therapy in the treatment landscape of urethral warts: A systematic review.

BACKGROUND: Human papilloma virus (HPV) infection is the most common sexually transmitted disease worldwide and the main cause of genital warts. Clear recommendations for the management of urethral warts, which are often hard to detect and difficult to treat, are still lacking. OBJECTIVE: To summarize all available data describing treatment modalities of urethral warts, compare their efficacy and side effects, and provide physicians a treatment strategy outline. MATERIAL AND METHODS: Till June 2020, we conducted a systematic review of articles studying the different treatment modalities of urethral condylomas. A chi-square test was used to compare the recurrence rates between treatment modalities, the complete clearance rates at first follow-up and the rates of adverse events. RESULTS: A total of 26 articles with 1730 patients were included in our review. 61 % of patients were deemed completely cured on the first follow-up while 21 % recurred. 5-aminolevulinic acid (ALA) mediated photodynamic therapy (PDT) was the most common treatment and yielded the lowest recurrence rate (7.5 %) followed by laser therapy (24 %) and topical therapy (31 %) (p < 0.01). ALA-PDT resulted in a higher rate of clearance on follow up (96 %) compared to laser therapy (69 %) and topical therapy (14 %) (p < 0.01). Adverse events were more frequent in the ALA-PDT group (69 %) compared to laser therapy (28 %) and topical treatment (30 %) (p < 0.01). CONCLUSION: ALA-PDT appears to be the most effective treatment of urethral condylomas in term of clearance and recurrence rate, but with a higher risk of adverse events. Management should be tailored to the type of lesion found at presentation.
