RESUMEN
BACKGROUND: India is witnessing an epidemic of dermatophytosis. The role of host immune response against fungi in chronicity and dissemination is topic of ongoing research. We conducted cross-sectional comparative study to determine the difference in Th1 (IFN-γ) and Th2 (IL4) response in serum and tissue between acute and localised vs. chronic and disseminated cases. METHODS: Patients (18-60 years) were divided in two groups-group A (n = 114, BSA <5%, single anatomic site, duration <6 months, n = 118) and group B (n = 107 BSA >10%, > one anatomic site, duration >12 months, n = 118). Clinical parameters along with serum levels of IgE, IL-4 and IFN-γ and expression of IL4 and IFN-γ in dermal infiltrate were compared between group. RESULTS: Trichophyton mentagrophytes complex was commonest causative fungi. Serum levels of IgE were significantly higher (median A-539.2, B-2901.0, p < .001) whereas levels IL-4(median A-21.3, B-20.4, p < .001) and IFN-γ(median A-9.6, B-5.1, p < .001) were significantly lower in chronic cases. Expression of IL-4 was observed in most biopsy specimens in both groups without any difference in intensity of staining. Expression of IFN-γ was not detected in all but one specimen across both the groups. Severe itching (OR:0.050, CI:0.018, 0.139, p < .001), sign of topical steroid abuse (OR:0.203,CI:0.077, 0.537; p = .001), ↓IFN-γ (OR:4.683, CI:1.634, 13.418; p = .004) correlated significantly and independently with chronic dermatophytosis. CONCLUSION: Our study shows chronic and disseminated cases of dermatophytosis differ immunologically in terms of higher IgE, and lower IL4 and IFN-γ. Expression of IL4 is present in tissue of both acute, localised and chronic disseminated cases. Expression of IFN-γ cannot be established in our study.

BACKGROUND & AIMS: Direct-acting antivirals (DAAs) are effective against hepatitis C virus and sustained virologic response is associated with reduced incidence of hepatocellular carcinoma (HCC). However, there is controversy over the use of DAAs in patients with active or treated HCC and uncertainty about optimal management of these patients. We aimed to characterize attitudes and practice patterns of hepatology practitioners in the United States regarding the use of DAAs in patients with HCC. METHODS: We conducted a survey of hepatology providers at 47 tertiary care centers in 25 states. Surveys were sent to 476 providers and we received 279 responses (58.6%). RESULTS: Provider beliefs about risk of HCC recurrence after DAA therapy varied: 48% responded that DAAs reduce risk, 36% responded that DAAs do not change risk, and 16% responded that DAAs increase risk of HCC recurrence. However, most providers believed DAAs to be beneficial to and reduce mortality of patients with complete response to HCC treatment. Accordingly, nearly all providers (94.9%) reported recommending DAA therapy to patients with early-stage HCC who received curative treatment. However, fewer providers recommended DAA therapy for patients with intermediate (72.9%) or advanced (57.5%) HCC undergoing palliative therapies. Timing of DAA initiation varied among providers based on HCC treatment modality: 49.1% of providers reported they would initiate DAA therapy within 3 months of surgical resection whereas 45.9% and 5.0% would delay DAA initiation for 3-12 months and >1 year post-surgery, respectively. For patients undergoing transarterial chemoembolization (TACE), 42.0% of providers would provide DAAs within 3 months of the procedure, 46.7% would delay DAAs until 3-12 months afterward, and 11.3% would delay DAAs more than 1 year after TACE. CONCLUSIONS: Based on a survey sent to hepatology providers, there is variation in provider attitudes and practice patterns regarding use and timing of DAAs for patients with HCC. Further studies are needed to characterize the risks and benefits of DAA therapy in this patient population.

OBJECTIVES: Vedolizumab is increasingly used to treat patients with ulcerative colitis (UC) and Crohn's disease (CD), however, its safety during the perioperative period remains unclear. We compared the 30-day postoperative complications among patients treated preoperatively with vedolizumab, anti-tumor necrosis factor (TNF)-α agents or non-biological therapy. METHODS: The retrospective study cohort was comprised of patients receiving vedolizumab, anti-TNF-α agents or non-biological therapy within 4 weeks of surgery. The rates of 30-day postoperative complications were compared between groups using univariate and multivariate analysis. Propensity score-matched analysis was performed to compare the outcome between groups. RESULTS: Among 443 patients (64 vedolizumab, 129 anti-TNF-α agents, and 250 non-biological therapy), a total of 144 patients experienced postoperative complications (32%). In multivariate analysis, age >65 (odds ratio (OR) 3.56, 95% confidence interval (CI) 1.30-9.76) and low-albumin (OR 2.26, 95% CI 1.28-4.00) were associated with increased risk of 30-day postoperative complications. For infectious complications, steroid use (OR 3.67, 95% CI 1.57-8.57, P=0.003) and low hemoglobin (OR 3.03, 95% CI 1.32-6.96, P=0.009) were associated with increased risk in multivariate analysis. Propensity score matched analysis demonstrated that the risks of postoperative complications were not different among patients preoperatively receiving vedolizumab, anti-TNF-α agents or non-biological therapy (UC, P=0.40; CD, P=0.35). CONCLUSIONS: In the present study, preoperative vedolizumab exposure did not affect the risk of 30-day postoperative complications in UC and CD. Further, larger studies are required to confirm our findings.

INTRODUCTION: Male Sickle cell disease (SCD) patients often have moderate to severe hypogonadism resulting in abnormal seminal fluid parameters due to testicular dysfunction. Hydroxyurea (HU), the only drug found to be effective in preventing morbidity and mortality in sickle cell disease patients has been found to further aggravate the testicular dysfunction. MATERIAL AND METHODS: This was a prospective study done at a tertiary care hospital over 26 months between September 2011 to October 2013. 100 male sickle cell disease patients of age group 15 to 45 years were recruited in the study. We evaluated seminal fluid indices in all patients and the effect of hydroxyurea on seminal fluid parameters. Hydroxyurea was given at low dose of 10mg/kg/day orally to patients with frequent vaso-occlusive crisis and frequent need of blood transfusion. Seminal fluid analysis was done according to WHO criteria before starting hydroxyurea and every 3 months after initiation of hydroxyurea. Patients with abnormal seminal parameters before hydroxyurea therapy were not given hydroxyurea therapy. Patients with abnormal sperm parameters were subjected for FNAC of testis. In sickle cell disease patients with hydroxyurea therapy, who developed abnormal seminal fluid parameters, hydroxyurea was stopped for 3 months and seminal fluid parameters were re-evaluated. Patients who had recovery of seminal indices after hydroxyurea cessation were restarted with hydroxyurea therapy at low dose. RESULTS: Among Sickle cell disease patients without hydroxyurea therapy, 18% of patients developed oligospermia and 4% developed azoospermia. Among sickle cell disease patients with hydroxyurea therapy, 20% of patients developed oligospermia and 10% developed azoospermia. Seminal fluid parameters reverted back to normal after stoppage of hydroxyurea for 3 months in 73% of patients. CONCLUSIONS: Alteration of sperm parameters is seen in a significant number of sickle cell disease patients. Also, alterations of seminal fluid parameters are exacerbated by hydroxyurea treatment even with low dose. Therefore, treatment with hydroxyurea in adolescent and adult male sickle cell disease patients should be preceded by routine assessment of seminal fluid parameters and followed up regularly every 3 months for any change in seminal fluid parameters for evidence of hydroxyurea toxicity.

Herein we report the syntheses and comparative photophysical, electrochemical, in vitro, and in vivo biological efficacy of 3-(1'-hexyloxy)ethyl-3-devinylpyropheophorbide-cyanine dye (HPPH-CD) and the corresponding indium (In), gallium (Ga), and palladium (Pd) conjugates. The insertion of a heavy metal in the HPPH moiety makes a significant difference in FRET (Förster resonance energy transfer) and electrochemical properties, which correlates with singlet oxygen production [a key cytotoxic agent for photodynamic therapy (PDT)] and long-term in vivo PDT efficacy. Among the metalated analogs, the In(III) HPPH-CD showed the best cancer imaging and PDT efficacy. Interestingly, in contrast to free base HPPH-CD, which requires a significantly higher therapeutic dose (2.5 µmol/kg) than imaging dose (0.3 µmol/kg), the corresponding In(III) HPPH-CD showed excellent imaging and therapeutic potential at a remarkably low dose (0.3 µmol/kg) in BALB/c mice bearing Colon26 tumors. A comparative study of metalated and corresponding nonmetalated conjugates further confirmed that STAT-3 dimerization can be used as a biomarker for determining the level of photoreaction and tumor response.

BACKGROUND: Despite compelling evidence that hydroxyurea is safe and effective in sickle cell disease, it is prescribed sparingly due to several barriers like knowledge gaps in certain genotypes, apprehension about its safety and toxicity, and limited resources. We undertook this study to find out the efficacy and safety of HU in patients with HbSß(+) -thalassemia with IVS1-5(GâC) mutation. PROCEDURE: We registered 318 patients with HbSß(+) -thalassemia with IVS1-5(GâC) mutation. Of these, 203 were enrolled for hydroxyurea treatment at a low and fixed dose of 10 mg/kg/day. One hundred four patients (Group-I: 37 children and Group-II: 67 adults) with ≥2 years of hydroxyurea treatment were studied. RESULTS: The rate of vaso-occlusive crises, requirement of blood transfusion and rate of hospitalization reduced from 3 to 0.5, 1 to 0 and 1 to 0 in Group-I and 3 to 0, 1 to 0 and 0.5 to 0 in Group-II respectively after HU therapy (P < 0.0001). %HbF level, hemoglobin, MCV and MCH increased significantly, whereas HbS, WBC, platelet count, serum-bilirubin and LDH levels decreased significantly after HU therapy. It has been observed that along with fairly subtle hematological changes following HU therapy, there was a substantial clinical improvement occurred in these patients. Transient myelotoxicity was observed in 4.8%. There was minimal gonadal toxicity without affecting reproductive function. CONCLUSION: In view of easy affordability, better acceptability, minimal toxicity, the need of infrequent monitoring and its potential effectiveness, low and fixed dose of hydroxyurea is suitable for treatment of patients with HbSß(+) -thalassemia in resource poor setting.

Background and objective Scalp dandruff, a prevalent dermatological condition marked by flaking and itching, affects a large segment of the population. Sun exposure, genetics, and dryness, along with winter conditions, indoor heating, and hard water, all contribute to moisture loss and scalp imbalance. This study aimed to evaluate the safety, efficacy, and tolerability of a novel regimen combining a scalp scrub with hydroxy acid derivatives for exfoliation and dandruff removal, and a serum containing copper tripeptide-1, witch hazel (Hamamelis virginiana), hesperidin, hyaluronic acid, and pea protein (Pisum sativum) for hydration and scalp health. Methods This prospective, interventional, open-label, single-center study assessed the safety, efficacy, and in-use tolerability of a scalp scrub and serum regimen for mild to moderate dandruff. Ethical approval was granted by ACEAS - Independent Ethics Committee and all participants provided written consent. The study evaluated changes in Adherent Scalp Flaking Score (ASFS), scalp hydration with the Corneometer® CM 825, hair thickness, hair density, and scalp condition using CASLite Nova. Scalp appearance and treatment usage perception were evaluated on day 1, day 8, and day 15. Statistical analysis was conducted using SPSS Statistics v29.0.1.0 (IBM Corp., Armonk, NY) and Microsoft Excel 2019, with results reported as p-values and 95% confidence intervals (CI). Results As per the ASFS scale for adherent scalp flaking, a significant improvement of 61.24% (p<0.0001) was observed by day 15. Assessments with CASLite Nova showed significant increases in hair density and hair thickness by 12.48% (p<0.0001) and 25.36% (p<0.0001), respectively. Regarding scalp condition, the proportion of individuals with a dry scalp and significant keratin decreased from 65.52% at baseline to 6.9% by day 15. The incidence of dry scalp with fine dandruff also decreased from 6.9% at baseline to 0% by day 15. Conversely, the percentage of individuals with a dry scalp and some keratin increased from 27.59% at baseline to 48.28% by day 15. Also, the proportion of subjects with a normal scalp, characterized by good hair density and thickness, increased from 0% at baseline to 44.83% by day 15. Scalp skin hydration, measured by Corneometer® CM 825, showed a significant improvement of 76.24% (p<0.0001) from baseline to day 15. Overall, there were notable enhancements in scalp appearance, with reductions in itchiness, redness, roughness, and scaliness. All subjects reported satisfaction with the treatment. Conclusions The ThriveCo scalp regimen (scalp scrub + serum) has been demonstrated to be both effective and safe in treating and reducing scalp dandruff in healthy adults. The regimen significantly reduced ASFS by effectively removing visible scalp flakes from day 1 to day 15 with continuous use. Furthermore, the kit improved overall scalp condition, increased skin hydration, and enhanced the scalp's appearance. The components include scalp scrub with hydroxy acid derivatives for exfoliation and dandruff removal, and a serum containing copper tripeptide-1, Hamamelis virginiana, hesperidin, hyaluronic acid, and pea protein (Pisum sativum) for hydration and overall scalp health over the 15-day treatment period. The synergistic effects of this regimen work to clear visible dandruff flakes, reduce adherent scalp flaking, rejuvenate the scalp, and simultaneously strengthen the hair.

RESUMEN
Introduction Acne is a common inflammatory condition characterized by comedones, papules, and pustules, often resulting from increased sebum production influenced by hormones such as insulin-like growth factor-1 and androgens. Factors like Cutibacterium acnes, medications, sun exposure, cosmetics, and genetics exacerbate acne. This study aims to assess the safety and effectiveness of a novel acne treatment regimen, including a cleanser and serum containing Diacnemide™ (manufactured by Beaucience India Private Limited, Faridabad, India), in improving acne symptoms in adults. Methods This prospective, interventional, open-label, single-center, single-arm clinical study was designed to evaluate the safety, efficacy, and in-use tolerability of the test treatment regimen (serum + cleanser) for facial acne. Ethical approval was obtained from the Independent Ethics Committee, and all participants provided written consent. The study assessed changes in the severity of acne by dermatological assessment using the Investigator's Global Assessment (IGA) scale, changes in inflammatory and non-inflammatory lesions, skin hydration, sebum levels, and facial blemishes using various bioinstrumentations from Courage+Khazaka Electronic GmbH, Germany - Visiopor® PP34N, Corneometer® CM 825, Sebumeter® SM 815, and Mexameter® MX 18, respectively. Evaluations were conducted at baseline, T15 minutes, day 8, and day 15 post-usage. Statistical analyses were performed using SPSS (version 29.0.1.0) and Microsoft® Excel 2019 software, with results reported using p-values and confidence intervals at a 5% significance level. Results Porphyrin measurements showed significant reductions over time, with a 27.18% decrease in quantity and a 39.86% reduction by day 15 (p < 0.0001). Porphyrin values dropped by 2.61% after 15 minutes and 7.82% by day 15 (p < 0.05). Skin hydration increased significantly, with a 97.54% increment after 15 minutes and a 102.74% increment by day 15 (p < 0.0001). Sebum levels were restored to normal levels with the dry skin observed at baseline, showing a 34.45% improvement on day 8 and 75.75% by day 15 (p < 0.0001). Facial dark spots were reduced by 10.66% by day 8 and 14.64% by day 15 (p < 0.0001), and erythema levels decreased significantly. Acne severity showed notable improvement, with 50% of the subjects having moderate acne at baseline, reduced to 20.69% with mild acne, and 79.31% with almost clear skin by day 15. Subject responses indicated high satisfaction, with 100% agreeing on the test treatment's effectiveness in reducing acne, oiliness, and inflammation and improving hydration and skin texture. Conclusion The ThriveCo acne regimen (serum + cleanser) manufactured by Anveya Living Private Limited, India, is both effective and safe for treating facial acne in healthy adults with acne. It significantly reduces porphyrin size and quantity, indicating a strong inhibition of P. acnes, and visibly improves dark spots and skin hydration. The components - Diacnemide™ and zinc pyrrolidone carboxylic acid - in the cleanser regulate sebum production and provide anti-inflammatory benefits, while the serum, containing Diacnemide™ and niacinamide, enhances skin barrier function and balances lipids. The synergistic effects of the ThriveCo Goodbye Acne Cleanser and Serum in this regimen effectively target surface bacteria like C. acnes and deeper follicular issues, promoting healthier skin and reducing acne-related symptoms.
RESUMEN
Introduction Scalp dandruff is a common dermatological condition characterized by flaking and itching of the scalp, affecting a significant portion of the population. Effective assessment methods are crucial for evaluating treatment outcomes. This study aimed to establish the reliability and correlation of three assessment techniques: Adherent Scalp Flaking Score (ASFS), phototrichogram using CASLite Nova, and the 60-second hair combing test. Methods This open-label, single-arm, single-center, prospective clinical study enrolled 12 adult subjects with mild to moderate dandruff. Evaluations were conducted before and after a standardized hair-wash intervention using three methods: ASFS, phototrichogram using CASLite Nova, and the 60-second hair combing test. The primary objective was to establish correlations between these assessment techniques. Inter-evaluator and inter-operator reliability were assessed using Fleiss Multirater Kappa. Results Significant reductions in dandruff were observed across all methods post-hair wash. The ASFS decreased from 23.67±2.06 at baseline to 6.67±4.46, showing a mean reduction of 17.00±5.22 (71.40%, p<0.001). phototrichogram analysis revealed that 60.42% of the total (n=96) scalp zones assessed were in normal condition post-hair wash compared to none at baseline. The 60-second hair combing test showed a reduction in non-adherent flakes, with 58.33% of subjects displaying light flakes and 41.67% showing no flakes post-hair wash. The chi-squared test indicated a significant association (p<0.001) between ASFS and phototrichogram results. Inter-evaluator variability for ASFS and the hair combing test demonstrated substantial agreement (Kappa=0.692 and 0.637, respectively, p<0.0001). Inter-operator reliability for phototrichogram also showed substantial agreement (Kappa=0.746, p<0.0001). Conclusion The study confirms the reliability and consistency of ASFS, phototrichogram, and the 60-second hair combing test in assessing scalp dandruff. The significant correlations of ASFS and phototrichogram via CASLite Nova validate their use in clinical settings. Comprehensive training for evaluators and operators is essential to achieve reproducible and accurate results. These findings provide a robust framework for future studies and clinical assessments of scalp dandruff.
RESUMEN
Hypereosinophilia can be primary, including idiopathic hypereosinophilic syndrome (HES) and chronic eosinophilic leukemia, or secondary/reactive to various infective and non-infective stimuli. Chronic oro-genital ulcerations can occur due to various dermatological and non-dermatological disorders, and many times it serves as a useful indicator of an underlying systemic disorder. Hence, a case presenting with chronic oro-genital ulcerations needs a thorough evaluation. We are reporting an interesting case of a middle-aged male who had chronic oro-genital ulcerations as a presenting feature of chronic eosinophilic leukemia with FIP1L1-PDGFRA fusion (FIP1-like 1/platelet-derived growth factor receptor alpha). The patient's oro-genital ulcerations responded excellently to imatinib.
RESUMEN
IL-17 mediates essential inflammatory responses in host defense and autoimmunity. The IL-17A-IL-17F signaling complex is composed of IL-17RA and IL-17RC, both of which are necessary for signal transduction. To date, the specific contribution of IL-17RC to downstream signaling remains poorly understood. To define the regions within the IL-17RC cytoplasmic tail required for signal transduction, we assayed signaling by a panel of IL-17RC deletion mutants. These findings reveal that IL-17RC inducibly associates with a specific glycosylated IL-17RA isoform, in a manner independent of the IL-17RC cytoplasmic tail. Using expression of the IL-17 target genes IL-6 and 24p3/lipocalin-2 as a readout, functional reconstitution of signaling in IL-17RC(-/-) fibroblasts required the SEF/IL-17R signaling domain (SEFIR), a conserved motif common to IL-17R family members. Unexpectedly, the IL-17RC SEFIR alone was not sufficient to reconstitute IL-17-dependent signaling. Rather, an additional sequence downstream of the SEFIR was also necessary. We further found that IL-17RC interacts directly with the adaptor/E3 ubiquitin ligase Act1, and that the functional IL-17RC isoforms containing the extended SEFIR region interact specifically with a phosphorylated isoform of Act1. Finally, we show that IL-17RC is required for in vivo IL-17-dependent responses during oral mucosal infections caused by the human commensal fungus Candida albicans. These results indicate that IL-17RC is vital for IL-17-dependent signaling both in vitro and in vivo. Insight into the mechanisms by which IL-17RC signals helps shed light on IL-17-dependent inflammatory responses and may ultimately provide an avenue for therapeutic intervention in IL-17-mediated diseases.

Acne vulgaris is a common dermatological condition characterized by hormonally-mediated sebum overproduction, follicular hyperkeratinization, and chronic inflammation of the pilosebaceous unit. Microbes, genetic susceptibilities, and various environmental factors have been linked to the pathogenesis of the condition. Over the last several years it has become apparent that patients with acne are under increased cutaneous and systemic oxidative stress. Moreover, the burden of oxidative stress may not be a mere consequence of acne; rather, the oxidative stress, lipid peroxidation in particular, may be an early event that helps to drive the acne process. Here, we explore the role of oxidative stress and review the preliminary research involving the administration of local and systemic antioxidants.

We report a novel post-loading approach for constructing a multifunctional biodegradable polyacrylamide (PAA) nanoplatform for tumor-imaging (fluorescence) and photodynamic therapy (PDT). This approach provides an opportunity to post-load the imaging and therapeutic agents at desired concentrations. Among the PAA nanoparticles, a formulation containing the photosensitizer, HPPH [3-(1'-hexyloxyethyl)pyropheophorbide-a], and the cyanine dye in a ratio of 2:1 minimized the undesirable quenching of the HPPH electronic excitation energy because of energy migration within the nanoparticles and/or Förster (fluorescence) resonance energy transfer (FRET) between HPPH and cyanine dye. An excellent tumor-imaging (NIR fluorescence) and phototherapeutic efficacy of the nanoconstruct formulation is demonstrated. Under similar treatment parameters the HPPH in 1% Tween 80/5% aqueous dextrose formulation was less effective than the nanoconstruct containing HPPH and cyanine dye in a ratio of 2 to 1. This is the first example showing the use of the post-loading approach in developing a nanoconstructs for tumor-imaging and therapy.

BACKGROUND: Acne vulgaris is a chronic, inflammatory skin condition of pilosebaceous units. The standard treatment involves topical and oral antibiotics, retinoids, benzoyl peroxide, and other synthetic compounds, mostly associated with adverse effects. Hence, herbal skincare products are considered nowadays. AIM: To evaluate the safety and efficacy of Purifying Neem Face Wash (PNFW), an herbal skincare product in the prevention and/or reduction of mild-to-moderate acne. METHODS: An open-label, single-center, single-arm, four-week clinical study was conducted with subjects having either mild-to-moderate acne or oily skin and non-existent acne. The performance of PNFW in the reduction and/or prevention of acne was detected by counting cutaneous inflammatory and non-inflammatory acne lesions in each of the four visits. Sebum level and skin hydration of both cheeks were measured via sebumeter and corneometer, respectively. Self-assessment questionnaires were used to assess the subjects' responses toward PNFW. RESULTS: Out of 120 study subjects, 79% and 72% showed either reduction or no new appearance of inflammatory and non-inflammatory acne lesions, respectively, from baseline to Visits 3 and 4. Skin sebum level and skin hydration showed a statistically significant decrease (p < 0.001) and increase (p < 0.001), respectively, in Visits 3 and 4. Self-assessment surveys showed the satisfaction of the subjects about the product in terms of condition improvement, ease in use, and fragrance. CONCLUSION: The present study indicated the beneficial effect of the herbal ingredients (neem and turmeric) of Himalaya's PNFW in the prevention and reduction of mild-to-moderate acne with no side effects.

Peripheral T-cell lymphoma (PTCL) comprises 5-20% of all non-Hodgkin lymphomas (NHL). These all have different morphological patterns, phenotypes, and clinical presentations making it a diverse group of lymphomas. PTCL, not otherwise specified (PTCL-NOS), is a subtype considered to have a poor prognosis and a low overall survival rate of only about 30-40%. We report a case of primary cutaneous PTCL-NOS presenting in a young pregnant female with multiple progressive, tender, and necrosed nodules all over her body for 3 months. Her skin biopsy findings led us to suspect malignancy, and via immunohistochemistry (IHC), her diagnosis was confirmed. Cutaneous lymphoma is a dangerous albeit rare entity and should be kept in mind when the commoner differentials have been ruled out.
