The Application of Umbilical Cord Blood-derived Platelet Gel for Skin Ulcers Associated With Chronic Graft-Versus-Host Disease in Pediatrics: A Randomized Trial.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a curative strategy against a variety of malignant and nonmalignant disorders. However, acute and chronic graft-versus-host disease (aGVHD and cGVHD, respectively) commonly complicate this approach, culminating in substantial morbidities and mortalities. The integumentary system is the preponderant organ involved in cGVHD, and its response to existing treatments, including well-versed immunosuppressants and novel targeted therapies, is not desirable. Despite the rarity, ulcers of sclerotic skin cGVHD are treatment-refractory and associated with significant morbidities and an exaggerated risk of infectious complications. Platelet-rich plasma (PRP) and its derivatives are endowed with growth factors and proangiogenic molecules and hold regenerative potential. This study aimed to assess the safety and efficacy of the application of platelet gel-containing dressing against ulcerative skin cGVHD in pediatric patients. This randomized trial is conducted at the hematopoietic stem cell transplantation unit of the Children's Medical Center Hospital in Tehran, Iran. Twenty-one pediatric patients (aged between 5 and 15 years) were initially enrolled, and 16 met the inclusion criteria. All cases (4 females) were recipients of allo-HSCT who had been complicated with symmetrically or near-symmetrically ulcerative sclerotic skin cGVHD. Fresh umbilical cord blood (UCB) was obtained from healthy donors and underwent centrifugation using a novel PRP preparation kit in a single-step process. Platelet gel was produced by adding thrombin to the isolated buffy coat layer. Two similar ulcers of each patient were randomized to receive either conventional dressing or platelet gels up to 6 times. At each time point evaluation, ulcer size and its relative reduction compared to the basal size were recorded. Included patients received a total of 80 platelet gel-containing dressings. While the mean sizes of randomized ulcers at the beginning of the study were similar, their differences became significant 15 days after the initiation of intervention (P = .019). In addition, the mean reduction in the ulcers' surface area (in comparison to their baseline values) was significantly higher for the intervention arm at all evaluation points (P = .001 for day 5 and P < .001 for subsequent time points). At the end of the trial, the number of ulcers with a more than 50% reduction in size was 14 (87.5%) in the intervention arm (including 6 completely healed ulcers) versus 1 (6.25%, which was not completely healed) in the control arm (P < .001). None of the patients exhibited any localized or systemic treatment-related adverse events. In this study, using a relatively large number of cases, we showed that UCB-derived platelet gel is a safe, feasible, and effective curative approach for skin ulcers of sclerotic skin cGVHD in pediatric patients. Designing upcoming trials on the efficacy of this therapeutic approach for ocular, mucosal, and acute skin GVHD is prudent.

Compounded Pain Formulations: What is the Evidence?

Pain syndromes are among the most widespread, costly, and debilitating of all neurological disorders. The number of patients living with chronic pain is expected to increase with the aging population and with the rise in obesity and diabetes across the nation. This type of pain is often insensitive to the traditional pain pharmacopeia or surgical intervention. Over the last 10 years the number of prescriptions that have been compounded by pharmacists has increased dramatically. There are a number of drugs in the area of pain management that have been formulated and compounded by pharmacists to treat conditions such as diabetic neuropathy, fibromyalgia, postherpetic neuralgia, joint pain, arthritis, and a variety of other conditions. A significant portion of these compounded analgesic preparations is made up of topical/transdermal dosage forms such as gels and creams. While the efficacy and doses of these drugs in systemic dosage forms have been widely established, little is known about the permeation and efficacy of these compounds from topical/transdermal gels. This review will provide an overview of chronic pain as a disease, the mechanisms of chronic pain, current treatment approaches to chronic pain, and a discussion of the drugs that are typically compounded into these topical formulations and studied in clinical trials.

Systemic platelet inhibition with localized chemotherapy by an injectable ROS-scavenging gel against postsurgical breast cancer recurrence and metastasis.

Early solid tumors benefit from surgical resection, but residual stubborn microtumors, pro-inflammatory microenvironment and activated platelets at the postoperative wound site are prone to recurrence and metastasis, resulting in poor prognosis. Here, we developed a dual-pronged strategy consisting of (i) in-situ forming ROS-scavenging gels loaded with anticancer drugs at the postoperative wound site to improve the tumor microenvironment and inhibit the recurrence of residual microtumors after orthotopic surgery, and (ii) systemic administration of clopidegrol via albumin nanoparticles for inhibiting activated platelets in the circulation thus inhibiting tumor remote migration. In a mouse model of postoperative recurrence and metastasis of orthotopic 4T1 breast cancer, the dual-pronged strategy greatly inhibited postoperative orthotopic tumor recurrence and reduced lung metastasis. This work provides an effective strategy for the postoperative intervention and treatment of solid tumors to inhibit postoperative tumor recurrence and metastasis, which has the potential to improve the prognosis and survival of patients with postoperative solid tumors. STATEMENT OF SIGNIFICANCE: Early-stage solid tumors benefit from surgical resection. However, the presence of residual microtumors, pro-inflammatory tumor microenvironment, and activated platelets at the postoperative wound site lead to recurrence and metastasis, ultimately resulting in poor prognosis. Here, we have devised a dual-pronged approach that includes (i) in-situ forming ROS-scavenging gels loaded with anticancer drugs (TM@Gel) at the wound site after surgery to enhance the tumor microenvironment (TME) and hinder the reappearance of residual microtumors, and (ii) systemic administration of clopidegrol through albumin nanoparticles (HHP) for inhibiting activated platelets in the circulation thus impeding tumor distant migration. This work provides a viable option for postoperative intervention and treatment of solid tumors to suppress postoperative tumor recurrence and metastasis.

A Review of Topical Sirolimus for the Treatment of Facial Angiofibromas in Tuberous Sclerosis Complex.

OBJECTIVE: This article assesses the efficacy, safety, pharmacology, and clinical applications of topical sirolimus 0.2% gel for the treatment of tuberous sclerosis complex (TSC)-associated facial angiofibromas. DATA SOURCES: A review of the literature was conducted using the Medline (PubMed) and EMBASE databases using the keywords topical sirolimus, rapamycin, Hyftor, and tuberous sclerosis. STUDY SELECTION AND DATA EXTRACTION: Articles written in English and relevant to the topic were included. DATA SYNTHESIS: In the phase 2 trial, the mean improvement factor, a composite measure of improved tumor size and redness, was achieved in all patient groups (P < 0.001) with significant responses among the adult and pediatric subgroups at week 12. There were no serious adverse events recorded. In the phase 3 trial, 60% of participants responded to treatment in the sirolimus group compared with 0% in the placebo group with different response rates between the adult and pediatric subgroups at week 12. Sirolimus gel had no serious adverse events, and dry skin was the most common adverse reaction. Patients who had completed the 12-week trials were then enrolled in a long-term trial; angiofibromas had response rates of 78.2% to 0.2% sirolimus gel. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON TO EXISTING DRUGS: Topical sirolimus 0.2% is a first-in-class, newly Food and Drug Administration (FDA)-approved, mammalian target of rapamycin (mTOR) inhibitor that is a promising and safe, noninvasive alternative to surgical procedures for TSC-associated angiofibromas. CONCLUSIONS: Topical sirolimus 0.2% gel is a moderately effective treatment for TSC-associated facial angiofibromas with an adequate safety profile.

Recent advances in stimuli-responsive tailored nanogels for cancer therapy; from bench to personalized treatment.

To improve the quality of health in a personalized manner, better control over pharmacologically relevant cargo formulation, organ-specific targeted delivery, and on-demand release of therapeutic agents is crucial. Significant work has been put into designing and developing revolutionary nanotherapeutics approaches for the effective monitoring and personalized treatment of disease. Nanogel (NG) has attracted significant interest because of its tremendous potential in cancer therapy and its environmental stimuli responsiveness. NG is considered a next-generation delivery technology due to its benefits like as size tunability, high loading, stimuli responsiveness, prolonged drug release via in situ gelling mechanisms, stability, and its potential to provide personalized therapy from the investigation of human genes and the genes in various types of cancers and its association with a selective anticancer drug. Stimuli-responsive NGs can be used as smart nanomedicines to detect and treat cancer and can be tuned as personalized medicine as well. This comprehensive review article's major objectives include the challenges of NGs' clinical translation for cancer treatment as well as its early preclinical successes and prospects.

Silica-based microencapsulation used in topical dermatologic applications.

Microencapsulation has received extensive attention because of its various applications. Since its inception in the 1940s, this technology has been used across several areas, including the chemical, food, and pharmaceutical industries. Over-the-counter skin products often contain ingredients that readily and unevenly degrade upon contact with the skin. Enclosing these substances within a silica shell can enhance their stability and better regulate their delivery onto and into the skin. Silica microencapsulation uses silica as the matrix material into which ingredients can be embedded to form microcapsules. The FDA recognizes amorphous silica as a safe inorganic excipient and recently approved two new topical therapies for the treatment of rosacea and acne. The first approved formulation uses a novel silica-based controlled vehicle delivery technology to improve the stability of two active ingredients that are normally not able to be used in the same formulation due to potential instability and drug degradation. The formulation contains 3.0% benzoyl peroxide (BPO) and 0.1% tretinoin topical cream to treat acne vulgaris in adults and pediatric patients. The second formulation contains silica microencapsulated 5.0% BPO topical cream to treat inflammatory rosacea lesions in adults. Both formulations use the same amorphous silica sol-gel microencapsulation technology to improve formulation stability and skin compatibility parameters.

Levodopa-Carbidopa Intestinal Gel Injection for Patient with Severe Parkinson's Disease Followed by Total Hip Arthroplasty: A Case Report and Literature Review.

BACKGROUND: Patients with Parkinson's disease have a high dislocation rate after total hip arthroplasty (THA). This study describes a case with severe Parkinson's disease who developed rapidly destructive coxarthrosis (RDC) and underwent THA using a dual mobility cup after a levodopa-carbidopa intestinal gel (LCIG) infusion. CASE PRESENTATION: The patient is a 59-year-old female with a ten-year history of Parkinson's disease, which was first treated with oral levodopa. The patient developed RDC of the right hip joint. However, THA was difficult owing to Parkinson's disease and its treatment side effects, such as wearing-off, dyskinesia, and freezing of the gait, Thus, LCIG was initiated, and improvement in wearing-off and dyskinesia was observed. Two months after the LCIG therapy, the disease was controlled well. THA was subsequently performed using a dual mobility cup to prevent postoperative dislocation. Postoperatively, LCIG therapy was continuously administered to carefully manage the disease, which was controlled well with no increase in wearing-off and dyskinesia after surgery. At 1 year after surgery, the walking speed, stride length, and the Harris hip score improved compared to preoperatively. The UPDRS III motor score improved to eight without signs of wearing-off or dyskinesia. The Hoehn-Yahr scale was II in the "on" period and remained unchanged 1 year after surgery. The patient could walk without a cane and had satisfactory functional outcomes. CONCLUSION: This case proved that LCIG treatment performed preoperatively, followed by THA using a dual mobility cup, and strict management of Parkinson's disease could result in a satisfactory clinical course without recurrence of wearing-off and dyskinesia. Similar procedures may benefit other patients with Parkinson's disease who have previously been deemed unsuitable for THA.

Efficacy and Safety of Topical Flutamide 1% Gel as an Adjunctive Therapy in the Treatment of Patients With Acne Vulgaris.

BACKGROUND: Acne vulgaris is a worldwide dermatological condition that has a complex pathophysiology in which androgens play an important role. Flutamide is a first-generation non-steroidal antiandrogen that can be used for acne treatment. AIM: To evaluate the potential therapeutic efficacy and safety of topical flutamide in the treatment of acne vulgaris. METHODS: A andomized controlled study included two equal groups, each had 27 patients, with a total of 54 patients with mild to moderate acne vulgaris having inflammatory (papules and pustules) and non-inflammatory (comedones) lesions. For eight weeks, Group (A) received 1% Flutamide topical gel on the face twice daily, whereas Group (B) served as the control group. RESULT: After 8 weeks of topical Flutamide 1% gel application twice daily, there was a significant reduction in papules count, and a highly significant reduction in pustules number from baseline. LIMITATIONS: We recommend that topical Flutamide 1% gel be tried on a larger number of patients with acne vulgaris, for longer therapeutic duration and follow up periods after treatment. CONCLUSION: Patients with acne vulgaris may find topical Flutamide 1% gel to be a viable, efficient, and safe solution with few adverse effects.

Comparison of the effect of tea tree oil eye gel with standard treatment in patients with anterior blepharitis: An open-label clinical trial.

Purpose: Daily cleansing of eyelids is very important to carry out a successful blepharitis treatment. However, there are no therapeutic guidelines for blepharitis. The aim was to compare the symptomatic relief of anterior blepharitis using Blephamed eye gel, a cosmetic product, versus standard treatment. Methods: The study was a prospective, interventional open label clinical trial at a university-based hospital. The test population was subjects aged 18-65 years who presented with mild to moderate anterior blepharitis. Eyelid hygiene was applied twice a day. At each visit, a detailed assessment of symptomatology was carried out. A two-way repeated measure mixed model ANOVA was used to compare two groups by time. Results: In total, 61 patients with mean age of 60.08 ± 16.69 years were enrolled in the study including 30 patients in standard group and 31 patients in Blephamed group. Two groups did not differ in terms of age (P = 0.31) and eye laterality (P = 0.50). The baseline scores of erythema, edema, debris, and symptoms as well as total score were similar between two groups (all P values >0.50). Two groups became different for all these parameters at day 45 (all P values <0.001). Significant interaction was detected between time and intervention groups for all severity parameters of blepharitis as well as total score (all P values <0.001). Conclusion: Eyelid hygiene with Blephamed more significantly decreased symptoms of anterior blepharitis compared to standard treatment.

Use of topical morphine gel in epidermolysis bullosa wounds-A series of case studies.

In recent years, the use of topical morphine gel has increased in the palliative care setting to reduce pain in chronic wounds and fungating tumours. However, there is a paucity of evidence to support its effectiveness. Epidermolysis bullosa (EB) is a rare genetic skin fragility disorder characterised by painful chronic wounds. Adequate control of wound pain can be challenging in this patient group due to other complexities associated with the more severe sub-types of the disease. Topical morphine gel has been used as an adjunct therapy in a small number of EB patients in our tertiary centre in an attempt to improve pain control and quality of life. The purpose of this paper is to demonstrate the efficacy of topical morphine gel used in a variety of EB wounds as well as patient reported reduction in pain through a series of case studies. The case studies suggest a positive effect of topical morphine gel on painful wounds across a spectrum of EB subtypes.

Enhanced skin localization of metronidazole using solid lipid microparticles incorporated into polymeric hydrogels for potential improved of rosacea treatment: An ex vivo proof of concept investigation.

Metronidazole (MNZ) is a nitroimidazole derivative antibiotic that has been generally used in the treatment of rosacea. However, it has low molecular weight and lipophilicity, limiting the effectiveness of MNZ in the topical treatment of rosacea. This study reports an MNZ-loaded solid lipid microparticle (SLM) gel formulation with sustained drug release effects required in the treatment of rosacea. SLM was formulated using the double emulsification method with five different concentrations of glyceryl monostearate (GMS) as a solid lipid used to encapsulate MNZ. All the MNZ-loaded SLM formulas were extensively characterized by various analytical tools. After optimized MNZ-loaded SLM formulation was obtained, then formulated into gel preparation. To obtain a gel formula with good physical characteristics and drug release in the development of topical therapy, the SLM-loaded gel was further evaluated, covering various parameters such as pH, viscosity, rheology, spreadability, extrudability, skin occlusivity, gel strength, permeation and retention ex vivo, as well as hemolysis tests and antioxidant activity. The evaluation results showed that the SLM formulations had desired properties with optimum encapsulation efficiency. Moreover, the gels prepared from carbomer possessed desired characteristics and were found to be hemocompatible. In addition, the gel formula with a carbomer concentration of 1.25 % can provide better drug release with the highest MNZ retention after 24 h of 2.35 ± 0.05 mg. Notably, the formulation of MNZ into SLM and hydrogel did not affect the antioxidant activity. Thus, it can provide continuous drug release, which could potentially be useful in increasing efficacy in rosacea therapy. The results obtained also showed a significant difference (p < 0.05) compared to the control formula and other formulas. Therefore, this study has proven a new approach to developing drug delivery systems for rosacea treatment.

Topical chlormethine gel in the treatment of mycosis fungoides: A single-center real-life experience and systematic review of the literature.

Gel formulation of chlormethine (CG) has gained a preeminent role among therapies available for mycosis fungoides (MF). To evaluate the frequency of use of CG for MF treatment and to determine the limits and potentialities of CG in a real-world setting. A systematic review of articles published prior to October 2021 was performed. Articles were included in the review if a full-text English version was available. MEDLINE (PubMed), Scopus, and Web of Science were each queried from their date of inception with the following terms: "mechlorethamine gel", "chlormethine gel", and "mycosis fungoides". The reference lists of the studies retrieved were searched manually. Moreover, this study included all consecutive patients with different stages of MF (from IA to IIB) who started treatment with CG gel between July 2020 and May 2021. Data of the literature were compared to our single-center real-life experience. Of the surveyed literature, 11 publications were included in the final analysis describing a total of 548 patients with MF. Eleven patients with a median (standard deviation) age of 66 years (15.1) were enrolled and followed up, receiving CG (0.02% chlormethine HCl). Response to treatment resulted higher (90.1%) in our study population than in other real-world experiences published in literature. This systematic review supports the role of CG for MF treatment, showing its limits and potentialities. Our single-center real-life experience revealed an elevated percentage of clinical response with high safety and tolerance, demonstrating its versatile use with dose and application rate adaptability.

[Real-time 3D reconstruction CT-jejunography guided direct percutaneous endoscopic jejunostomy for levodopa-carbidopa intestinal gel treatment in a patient with prior gastrojejunostomy].

A 68-year-old woman with Parkinson's disease, who had previously undergone Roux-en-Y gastrojejunostomy for early gastric cancer, complained of wearing-off and troublesome dyskinesia that had progressed over 7-years. After the introduction of levodopa-carbidopa intestinal gel therapy (LCIG) by nasojejunal tube, she had a good clinical response. Percutaneous endoscopic gastrostomy with a jejunal extension tube was difficult in this case, due to lack of gastrostomy site and fibrous postoperative adhesion. We introduced LCIG by direct percutaneous endoscopic jejunostomy (D-PEJ) which offers a less invasive procedure to operative tube placement. The factors affecting the success of D-PEJ could interfere with transillumination, abdominal thickness and the location of other organs. We determined the optimum site of catheter insertion with the assistance of real-time 3D reconstruction CT-jejunography. She was discharged home on postoperative day 14 without any procedure-related complications. Real-time 3D reconstructive CT-jejunography guided D-PEJ is a useful method for a patient who benefit from LCIG with prior gastrojejunostomy.

Facial Edema Associated with Dasatinib: Case Report with Successful Treatment.

INTRODUCTION: Tyrosine kinase inhibitors (TKI) are an effective treatment option for chronic myeloid leukemia (CML). The most common associated adverse effects of TKI include thrombocytopenia, neutropenia, nausea, vomiting, and diarrhea. Facial edema is a rare adverse reaction that may cause significant psychological burden. Treatment is life-long in many cases therefore it is vital to have options available to manage these adverse effects. CASE REPORT: We present a 70-year-old female with a medical history of CML, diabetes, hypertension, and hypercholesterolemia who presented to our dermatology clinic for chief complaint of worsening edematous facial rash beginning after initiation of dasatinib. We were able to achieve significant improvement with a regimen that allowed her to remain on dasatinib. MANAGEMENT AND OUTCOME: We treated the patient with a novel, unreported regimen of topical metronidazole 1% gel to be applied every morning and topical tacrolimus 0.1% ointment to be applied twice daily. She had significant improvement with the treatment and was continued on this topical regimen indefinitely. DISCUSSION: Previous reports of treatment options available for TKI-associated facial edema include topical and systemic corticosteroids, which can cause long-term side effects int the context of long-term TKI use. Our patient achieved an acceptable reduction in facial edema and rash with our combination regimen of metronidazole gel and tacrolimus ointment. We present the only such case of successful treatment of facial edema associated with a tyrosine kinase inhibitor. We encourage future studies on the efficacy and safety of this regimen to treat this adverse effect.

Efficacy and Safety of Propranolol Gel for Infantile Hemangioma: A Randomized, Double-Blind Study.

We aimed to evaluate the efficacy and safety of propranolol gel at various concentrations with infantile hemangiomas after proliferative phases. We designed a single-center, randomized, double-blind, dose-dependent trial with placebo control and randomized patients to receive propranolol gel at 0, 1, or 5%, twice daily for 24 weeks. The primary efficacy endpoint was the percentage change in redness of the tumors. Safety endpoints were skin characteristics changes and systemic symptoms. We made two comparisons to evaluate the superiority of 1 and 5% propranolol gels against placebo for primary endpoint analysis and used the t-test to compare parents' satisfaction with these treatments. Initially, 19 patients were enrolled, but 8 were excluded from the analysis. We were underpowered to answer the question of efficacy. In the per-protocol set, we found similar results for the redness percentage change among the patients on placebo, 1 and 5% gel. However, the difference in redness before and after treatment suggested a slight decreasing trend of lesion's redness as the propranolol concentration increased. The difference in parents' satisfaction between the placebo and 5% propranolol gel groups was significant (p = 0.08). We observed no serious adverse events. We did not find an obvious dose-dependent effect for the propranolol gel treatment against infantile hemangiomas after the proliferative phase. However, external applications twice daily were less burdensome for parents and led to good compliances. It had a favorable safety profile in Japanese pediatric patients with infantile hemangiomas.

A topical gel of tea tree oil nanoemulsion containing adapalene versus adapalene marketed gel in patients with acne vulgaris: a randomized clinical trial.

Adapalene is used for treatment of acne vulgaris, a common dermatological disease. Nano-based carriers have been developed to improve solubility and bioavailability of adapalene and other acne treatment drugs. In our previous report, tea tree oil nanoemulsion containing adapalene gel (TTO NE + ADA Gel) showed appropriate physical and biological properties such as stability, viscosity, pH, size, morphology and biocompatibility in an animal model. The present study was designed to assess efficacy and safety of the TTO NE + ADA Gel in comparison with 0.1% adapalene marketed gel (ADA Marketed Gel). A total of 100 patients were randomized to receive TTO NE + ADA Gel or ADA Marketed Gel, once daily at night, for 12 weeks. Analysis for efficacy was conducted by acne lesion count (total, inflammatory and non-inflammatory) and acne severity index at weeks 4, 8 and 12 using generalized estimating equation along with the safety assessments in each measurement for assessing dryness, erythema, burning sensation and irritation. Significantly better reduction in total, inflammatory, and non-inflammatory acne lesions were reported for TTO NE + ADA Gel as compared to the ADA Marketed Gel overall and on each measurement occasion (p value < 0.001 for all). Mean acne severity index also reduced with TTO NE + ADA Gel significantly in comparison with ADA Marketed Gel (p value < 0.001). Dryness was the most common adverse effect reported in both groups and it was higher in TTO NE + ADA Gel group. In conclusion, TTO NE + ADA Gel compared to ADA Marketed Gel appears more effective in the treatment of acne vulgaris, with no important change in adverse effects.

Intravesical In Situ Immunostimulatory Gel for Triple Therapy of Bladder Cancer.

Bladder cancer displays multiple biological features aided in drug resistance; therefore, single therapy fails to induce complete tumor regression. To address this issue, various kinds of cell death of cancer cells as well as restoring tumor immune microenvironment need to be taken into consideration. Here, we introduce a gel system termed AuNRs&IONs@Gel, which target-delivers a combination of photothermal, ferroptotic, and immune therapy through intravesical instillation. AuNRs&IONs@Gel consists of a gel delivery platform, embedded gold nanorods (AuNRs), and iron oxide nanoparticles (IONs). The targeted delivery gel platform provides dextran aldehyde-selective adhesion with cancer collagen. In this condition, photothermal therapy can be performed by gold nanorods (AuNRs) under imaging-guided near-infrared radiation. Local high concentrations of IONs can be absorbed by cancer cell to induce ferroptosis. Moreover, tumor-associated macrophages which often display an immune-suppressive M2-like phenotype will be repolarized by IONs into the antitumor M1-like phenotype, exerting a direct antitumor effect and professional antigen presentation of dead cancer cells. This process triggers a potent immune response of innate and adapt immunities to protect tumor rechallenge in long terms. Our triple-therapy strategy employs FDA-approved nanoparticles to inhibit bladder cancer which may possess great potential for clinical translation.

Efficacy of Curcumin Gel on Zinc, Magnesium, Copper, IL-1ß, and TNF-α in Chronic Periodontitis Patients.

Curcumin exhibits antibacterial, antioxidant, and anti-inflammatory effects and has been suggested as a treatment for inflammatory diseases. The study is aimed at evaluating the effect of curcumin gel on serum levels of micronutrients (zinc, copper, and magnesium) and proinflammatory cytokines (IL-1ß and TNF-α) in chronic periodontitis patients. Ninety subjects with an age of 25-54 were included in this study. From the total number, 30 subjects with healthy periodontium (control group) (mean age = 37.30 ± 7.08) were employed for the sole purpose of obtaining the normal mean values of clinical, chemical, and immunological parameters, and 60 with chronic periodontitis (mean age = 36.73 ± 6.22) were divided randomly into 2 groups, of which each group included 30 subjects. Group A received scaling and root planing SRP and curcumin gel injection covered by Coe pack for 7 days, and group B received SRP alone covered by Coe pack. Clinical parameters (plaque index, gingival index, bleeding on probing, pocket depth, and clinical attachment loss measurements) and blood samples were collected before and after 1 month of treatment to measure serum levels of zinc, copper, magnesium, IL-1ß, and TNF-α. The results showed significant micronutrient alteration and increase of proinflammatory cytokines in the chronic periodontitis group as compared to healthy control (P ≤ 0.05), and curcumin gel had a significant effect on the reduction of IL-1ß, TNF-α, copper, and clinical parameters (P ≤ 0.05) and increase of zinc and magnesium levels after 1 month as compared to baseline (P ≤ 0.05), nearly the same pattern for group B but with nonsignificant differences for Zn (P > 0.05). In conclusion, curcumin gel resulted in a more significant reduction in clinical parameters, inflammatory mediators, and copper and increase of zinc and magnesium levels as compared to SRP alone.

A New Thermo-Responsive Hyaluronic Acid Sol-Gel to Prevent Intrauterine Adhesions after Hysteroscopic Surgery: A Randomized, Non-Inferiority Trial.

PURPOSE: To investigate the efficacy and safety of a newly developed thermo-responsive sol-gel, ABT13107, for reducing the formation of intrauterine adhesions (IUAs) after hysteroscopic surgery. MATERIALS AND METHODS: In this multicenter, prospective, randomized trial (Canadian Task Force classification I), 192 women scheduled to undergo a hysteroscopic surgery at one of the eight university hospitals in South Korea were randomized into the ABT13107 group or the comparator (Hyalobarrier®) group in a 1:1 ratio. During hysteroscopic surgery, ABT13107 or Hyalobarrier® was injected to sufficiently cover the entire intrauterine cavity. RESULTS: The patients returned to their respective sites for safety assessments at postoperative weeks 1 and 4 and for efficacy assessments at postoperative week 4. The post-surgery incidence of IUAs was 23.4% in the ABT13107 group and 25.8% in the comparator group; this difference met the criteria for ABT13107 to be considered as not inferior to the comparator. No differences were found in the extent of adhesions, types of adhesions, or the cumulative American Fertility Society score between the two treatment groups. Most adverse events were mild in severity, and no serious adverse events occurred. CONCLUSION: ABT13107, a new anti-adhesive barrier containing hyaluronic acid, was not inferior to the highly viscous hyaluronic acid anti-adhesive barrier, Hyalurobarrier® in IUA formation after hysteroscopic surgery (Clinical trial registration No. NCT04007211).
