Compliance with tetracycline eye ointment during annual mass drug administration for trachoma control in the Amhara region, Ethiopia.

OBJECTIVES: A 6-week course of tetracycline eye ointment is an alternative to single -dose oral azithromycin in annual mass drug administration for trachoma control. Compliance with the recommended tetracycline eye ointment regimen has not been well characterised when administered as part of a trachoma control program. METHODS: A routine mass drug administration for trachoma was carried out in 40 communities in the Amhara region of Ethiopia. Two tubes of tetracycline eye ointment, to be administered twice daily for 6 weeks, was offered to all children under 6 months of age, to pregnant women who declined to take azithromycin, and to all individuals with a macrolide allergy. Seven weeks following the mass drug administration, a treatment compliance survey was performed for all community members documented to have received tetracycline eye ointment during the mass drug administration. RESULTS: Of the 491 individuals documented as having received tetracycline eye ointment from the treatment records, 367 completed the survey, of which 214 recalled being offered tetracycline eye ointment. A total of 105 (49%) respondents reported taking ≥1 daily dose of tetracycline eye ointment on most days of the week for at least the first week. Only 20 (9%) respondents reported taking at least 1 tetracycline eye ointment dose per week for 6 weeks. The most common reasons for low compliance included 'saving it for a future infection' and 'stopped because I (or my child) seemed healthy'. The odds of low compliance were greater for those who reported not having adequate counselling (e.g., odds ratio [OR] 5.3, 95% CI 2.5-28.9 when low compliance was defined as not taking a tetracycline eye ointment dose for most days of at least the first week). CONCLUSIONS: Compliance with tetracycline eye ointment was low when administered by a trachoma program during a routine mass drug administration, especially for those reporting inadequate counselling. Further research with a larger sample size and varied settings is warranted to better understand and improve compliance.

Efficacy and safety of crisaborole ointment, 2%, in participants aged ≥45 years with stasis dermatitis: Results from a fully decentralized, randomized, proof-of-concept phase 2a study.

BACKGROUND: Crisaborole ointment, 2%, is a nonsteroidal topical phosphodiesterase 4 inhibitor approved for the treatment of mild-to-moderate atopic dermatitis. OBJECTIVE: To evaluate the efficacy and safety of crisaborole in stasis dermatitis (SD). METHODS: In this randomized, double-blind, vehicle-controlled, decentralized phase 2a study (NCT04091087), 65 participants aged ≥45 years with SD without active ulceration received crisaborole or vehicle (1:1) twice-daily for 6 weeks. The primary end point was percentage change from baseline in total sign score at week 6 based on in-person assessment. RESULTS: Crisaborole-treated participants had significantly reduced total sign score from baseline versus vehicle based on in-person (nondermatologist) assessment (-32.4% vs -18.1%, P = .0299) and central reader (dermatologists) assessment of photographs (-52.5% vs -10.3%, P = .0004). Efficacy according to success and improvement per Investigator's Global Assessment score and lesional percentage body surface area reached statistical significance based on central reader but not in-person assessments. Skin and subcutaneous tissue disorders were common all-causality treatment-emergent adverse events with crisaborole. LIMITATIONS: Small sample size and short treatment duration were key limitations. In-person assessment was not conducted by dermatologists. CONCLUSION: Crisaborole improved signs and symptoms of SD and was well tolerated. Central reader assessment represents a promising approach for siteless clinical research.

Effectiveness and tolerability of rectal ointment and suppositories containing sucralfate for hemorrhoidal symptoms: a prospective, observational study.

BACKGROUND AND AIMS: A high number of topical products are available for the treatment of hemorrhoidal symptoms. Sucralfate-based topical products constitute a new treatment alternative that act as a mechanical barrier to facilitate healing. The aim of this prospective, observational study was to determine patient- and physician-assessed effectiveness and tolerability of rectal ointment and suppositories containing sucralfate for the treatment of hemorrhoidal symptoms in routine clinical practice. METHODS: Adult patients with diagnosed, mild-to-moderate, symptomatic non-bleeding hemorrhoids treated with rectal ointment or suppositories containing sucralfate were enrolled. Patients were administered treatment twice per day for at least 1 week until symptom resolution and/or for a maximum of 4 weeks. The primary endpoint was patient-assessed effectiveness on a modified Symptom Severity Score (mSSS, range 0 to 14). Physician-assessed effectiveness (9 symptoms, 0 to 5 Likert scale), hemorrhoid grade, and patient satisfaction were also determined. RESULTS: Five investigators enrolled 60 patients; mean age was 48.4 ± 16.6 years and 72.4% were female. Pain or pressure sensitivity was reported as the most severe symptom by patients, and pressure sensitivity, discharge, soiling, and prolapse by physicians. Mean patient-assessed mSSS at baseline was 6.6 ± 1.9 and was significantly improved overall and in the ointment and suppository groups individually by -4.6 ± 2.0, -4.4 ± 1.8, and -4.8 ± 2.2, respectively (p < 0.0001). Investigator-assessed mean baseline symptom score was 18.1 ± 3.9 and improved by -7.1 ± 4.5, -6.9 ± 5.4, and -7.3 ± 3.5, respectively (p < 0.0001). Investigator-assessed symptoms of pressure sensitivity, swelling, and discharge were improved to the greatest extent. Hemorrhoid grade was improved in 38% of patients at the end of treatment. Compliance with treatment was 97.4% and patient satisfaction with application and onset of action was high (81.3% and 76.2%, respectively). Both the ointment and suppository were well tolerated. CONCLUSIONS: The effectiveness of topical ointment or suppository containing sucralfate on patient- and investigator-assessed hemorrhoidal symptoms in real-life clinical practice was demonstrated. Patient satisfaction was high and treatments were well tolerated. Larger controlled trials are warranted to confirm the results.

Isolation, structural elucidation of bioactive compounds and their wound-healing ability, antibacterial and In silico molecular docking applications.

Andrographis echioides has been extensively utilized in traditional Indian folk medicines for several skin disorders and other biological actions such as diuretic, antimicrobial, anthelmintic, anti-ulcer, and hepatoprotective properties. Different crude extracts were extracted from A. echioides leaves using various solvents such as methanol and water. The prepared crude extracts were utilized to formulate different herbal ointments. Further, the prepared ointments were examined against wounds and bacterial pathogens. The wound healing ability of the prepared formulations was observed for F1, F2, and F3, to be (89.84%, 95.11%, and 95.75%) respectively. Moreover, wound healing capabilities were compared with standard Betadine which exhibits 98.12%, those results indicating that the prepared herbal ointment also has a promising wound healing ability. The F2 formulations outperform the other two formulations (F1 and F2) in terms of their antibacterial ability to combat Staphylococcus aureus, Klebsiella pneumoniae Bacillus subtilis, and Escherichia coli. Moreover, there are two compounds were successfully isolated and identified from methanolic extract, which are 2-(3,4-dihydroxyphenyl)-3,4-dihydro-2H-chromene-3,5,7-triol and 3-(3,4-Dihydroxyphenyl)-2-propenoic acid. Meanwhile, the molecular docking investigation exposed high binding energy Staphylococcus aureus TyrRS (-8.9 kcal/mol), Isoleucyl-tRNA synthetase (-7.5 kcal/mol), Penicillin-binding protein 2a (-8.0 kcal/mol), S. aureus DNA Gyrase (-7.2 kcal/mol), GSK-3beta (Glycogen synthase kinase-3 beta) (-8.3 kcal/mol) and TGF - Beta Receptor Type 1 Kinase Domain (-8.7 kcal/mol) indicating high degree of interaction between Compound-1 2-(3,4-dihydroxyphenyl)-3,4-dihydro-2H-chromene-3,5,7-triol (DHPDHC) and 7 clinically important skin infective pathogen Staphylococcus aureus proteins at the active sites. Additionally, the standard drug Povidone iodine, Sulphothiazole, and Nitrofurazone (<-8 kcal/mol), displayed low binding affinity on targeted proteins. A molecular dynamics simulation research with high free energy showed stable interaction between the ligand and protein. Which endorses the capabilities of A. echioides derived compounds as a potential wound healer and antibacterial therapeutic candidate for drug development in the future.

Effect of black cloth ointment on hypertrophic scar formation: An investigation using integrated network pharmacology and animal assay.

BACKGROUND: Hypertrophic scars (HS) are a common disfiguring condition in daily clinical encounters which brings a lot of anxieties and concerns to patients, but the treatment options of HS are limited. Black cloth ointment (BCO), as a cosmetic ointment applicable to facial scars, has shown promising therapeutic effects for facial scarring. However, the molecular mechanisms underlying its therapeutic effects remain unclear. MATERIAL AND METHODS: Network pharmacology was first applied to analyze the major active components of BCO and the related signaling pathways. Subsequently, rabbit ear scar model was successfully established to determine the pharmacological effects of BCO and its active component ß-elemene on HS. Finally, the molecular mechanism of BCO and ß-elemene was analyzed by Western blot. RESULTS: Through the network pharmacology, it showed that ß-elemene was the main active ingredient of BCO, and it could significantly improve the pathological structure of HS and reduce collagen deposition. BCO and ß-elemene could increase the expression of ER stress-related markers and promote the increase of apoptotic proteins in the Western blot experiment and induce the apoptosis of myofibroblasts. CONCLUSIONS: Our findings indicate that the material basis for the scar-improving effects of the BCO is ß-elemene, and cellular apoptosis is the key mechanism through which the BCO and ß-elemene exert their effects.

308 nm excimer laser and tacrolimus ointment in the treatment of facial vitiligo: a systematic review and meta-analysis.

This study aimed to investigate the effects and safety of 308 nm excimer laser (308 nm EL) and tacrolimus ointment (TO) in the treatment of facial vitiligo (FV). We searched Cochrane Library, PUBMED, EMBASE, CNKI, and WANGFANG from inception to June 1, 2023. Outcomes included overall response rate (ORR), total adverse reaction rate (TARR), recurrence rate at 3-month (RR-3) and recurrence rate at 6-month (RR-6). The outcome data were presented as odds ratios (OR) with 95% confidence intervals (CI). The risk of bias was assessed by Cochrane risk-of-bias tool and data analysis was performed by RevMan 5.4 software. This study included a total of 19 trials involving 2085 patients. When comparing 308 nm EL monotherapy with 308 nm EL plus TO, significant differences in the ORR (OR = 4.29, 95% CI [2.97, 6.19], I2 = 0%, P < 0.001), RR-3 (OR = 0.18, 95% CI [0.05, 0.69], I2 = 0%, P = 0.01), and RR-6 (OR = 0.38, 95% CI [0.14, 1.03], I2 = 39%, P = 0.06) were found between the two managements. When comparing TO monotherapy with TO plus 308 nm EL, its results showed significant differences in the ORR (OR = 4.21, 95% CI [2.90, 6.11], I2 = 0%, P < 0.001), TARR (OR = 0.42, 95% CI [0.22, 0.81], I2 = 4%, P = 0.009), and RR-3 (OR = 0.32, 95% CI [0.01, 8.03], P = 0.49) between the two modalities. The results of this study suggest that the combination of 308 nm EL and TO is more effective than either treatment alone for the treatment of FV.

Fitostimoline® in fibro-endoscopic and trans-nasal trans-speculum septoplasty as a beneficial tool to improve post-surgical outcome: Preliminary results of a case-control study.

OBJECTIVES: Topic treatment can be useful to improve short and long-term nasal outcomes after nasal surgery, reducing discomfort and risk of synechia. This study aimed at evaluating the effect on clinical outcomes of nasal packaging using Fitostimoline® gauze in FESS and septoplasty. METHODS: A case-control study on hospitalized patients was performed in a tertiary referral center. The control group included 20 patients treated with the standard surgical protocol for septoplasty and standard nasal packaging; treatment group included 21 patients underwent same surgical procedure but in whom the nasal tampon was wrapped with a gauze containing Fitostimoline® before being placed into the nose. RESULTS: Patients in treatment group had better outcomes than control; nasal mucosa showed better healing - recovery of normal color- in those patients in whom we applied the Fitostimoline® gauze around tampons. Moreover, 100 % patients in the treatment group did not refer discomfort during at tampon removal versus 60 % subjects in the control group who referred pain, tension or tearing during the same action. CONCLUSION: Our results, although preliminary because of the small cohort of subjects included, suggest that the apposition of a gauze with Fitostimoline® after nasal surgery might improve the mucosal healing with consequent reduction of patients discomfort during the post-surgical period.

Efficacy of Daiwenjiu ointment on the treatment of cervical spondylosis with nerve root type caused by cold dampness obstruction.

OBJECTIVE: This study aimed to assess the clinical efficacy of Daiwenjiu ointment in the treatment of cervical spondylosis with cold dampness obstruction nerve root type. METHODS: A retrospective analysis was conducted on a cohort of 110 patients diagnosed with cervical spondylotic radiculopathy. Based on the treatment method, the patients were divided into two groups. The control group received electroacupuncture treatment, while the observation group received a combination of Daiwenjiu ointment and electroacupuncture treatment. The outcome measures included Japanese Orthopedic Association (JOA) scores for cervical spine function, Simplified McGill Pain Questionnaire (SF-MPQ) scores, and changes in serum inflammatory factors TNF-α and IL-1ß. RESULTS: Following treatment, the JOA score in the observation group increased from 9.45 ± 1.35 to 14.82 ± 1.29 after treatment, indicating better recovery of cervical spine function compared to the control group (p < 0.001). The SF-MPQ score in the observation group decreased to 18.25 ± 3.80 after treatment, while it remained at 30.20 ± 4.30 in the control group. This difference between the groups was statistically significant (p < 0.001). Furthermore, the observation group demonstrated a significant decrease in serum levels of TNF-α and IL-1ß after treatment compared to the control group (p < 0.001). CONCLUSION: Daiwenjiu ointment exhibits significant therapeutic effects in patients with cold dampness obstruction nerve root type cervical spondylosis. It effectively improves cervical function, reduces pain, and downregulates inflammatory cytokine levels.

Effectiveness of preoperative micronized purified flavonoid fraction treatment and sucralfate-based rectal ointment on hemorrhoidal disease: A case-matched analysis.

BACKGROUND: Hemorrhoidal disease (HD) significantly impacts patients' quality of life. This study aimed to evaluate the effectiveness of preoperative treatment with the micronized purified flavonoid fraction (MPFF) and a sucralfate-based rectal ointment in managing HD symptoms and reducing interventions. METHODS: A prospective quasi-experimental study including consecutive cases and controls matched on the basis of sex was performed in a tertiary referral center. Cases received systemic and local therapy for HD, consisting of a rectal ointment containing 3% sucralfate and herbal extracts plus MPFF, in addition to conservative therapy, while controls received conservative therapy alone. The hemorrhoidal disease symptom score (HDSS), the Short Health Scale for HD (SHS-HD) score, and the Vaizey Incontinence Score were used to evaluate symptoms severity and their impact on quality of life and continence. Intervention requirements were assessed at baseline (T0) and after 60 days of treatment (T1). RESULTS: Between January and December 2023, a total of 98 patients were assessed for eligibility. After exclusions, 56 patients were enrolled, with 28 in each group. Significant improvements were observed in HD symptom scores from T0 to T1: the intervention group showed a mean change in HDSS of -9 [95% confidence interval (CI) -10 to -8], and the control group showed no significant change (mean change of 0; 95% CI -1.5 to 0). At T1, a higher proportion of patients in the intervention group underwent less invasive interventions compared with controls (18% versus 11%). Age, treatment group, and baseline symptom severity significantly predicted post-treatment symptom scores. CONCLUSIONS: In our study the preoperative treatment with MPFF and a sucralfate-based rectal ointment demonstrated clinical benefits in managing HD symptoms and reducing interventions. Further prospective trials are warranted to confirm and explore additional therapeutic strategies.

Comparative efficacy of Salix aegyptiaca's active compound versus phenytoin in healing full-thickness rat skin wounds: An animal model study.

BACKGROUND: Wound healing poses a challenging therapeutic scenario, requiring diverse clinical approaches. OBJECTIVES: This study aims to assess the wound-healing potential of Salix aegyptiaca's flower ointment compared to phenytoin, considering the active constituents of S. aegyptiaca and its traditional usage. METHODS: Initially, the active components of S. aegyptiaca were isolated and identified through the GC-MS technique. Subsequently, for the experimental intervention, thirty-five rats were divided into five distinct groups: control (C), phenytoin (F), and three S. aegyptiaca ointment groups at different concentrations (5 % - S5, 25 % - S25, and 50 % - S50). Anesthesia was administered, and wounds were induced on the animals' necks following a standard procedure. These wounds were then treated for a duration of 21 days. Wound healing progress was quantified, and histopathological assessments were conducted using hematoxylin and eosin staining and Mason's trichrome staining. RESULTS: The main active compounds of S. aegyptiaca, namely n-hexadecanoic acid and oleic acid, were identified via GC-MS analysis. Although the initial group weights did not show a significant difference (P = 0.271), a significant variation was observed in the final weights (P = 0.003). The S50 group exhibited a lower wound healing rate than the S25 group on the 7th and 14th days but surpassed it on the 21st day (C < F < S5≈S25

Local nasal immunotherapy with birch pollen-galactomannan conjugate-containing ointment in mice and humans.

BACKGROUND: Allergen immunotherapy (AIT) is the only disease-modifying treatment for immunoglobulin (Ig) E-mediated allergy. Owing to the high prevalence and early onset of hay fever and pollen-food allergy syndrome (PFAS), a safer and simpler treatment method than conventional AIT is needed. To develop a local nasal immunotherapy using an ointment containing hypoallergenic pollen and assess its efficacy in mice and healthy humans. METHODS: Hypoallergenicity was achieved by combining pollen and galactomannan through the Maillard reaction to create birch pollen-galactomannan conjugate (BP-GMC). The binding of galactomannan to Bet v 1 was confirmed using electrophoresis and Western blotting (WB). Binding of specific IgE antibodies to BP-GMC was verified using enzyme-linked immunosorbent assay (ELISA) and basophil activation test (BAT). The localization of BP-GMC absorption was confirmed using a BALB/c mouse model. BP-GMC mixed with white petrolatum was intranasally administered to 10 healthy individuals (active drugs, 8; placebo, 2) for 14 days. RESULTS: In electrophoresis and WB, no 17-kDa band was observed. In ELISA and BAT, BP-GMC did not react to specific IgE but was bound to IgA and IgG. In the mouse model, BP-GMC was detected in nasopharyngeal-associated lymphoid tissues. In the active drug group, the salivary-specific IgA level significantly increased on day 15 (p = 0.0299), while the serum-specific IgG level significantly increased on day 85 (p = 0.0006). CONCLUSIONS: The BP-GMC ointment rapidly produced antagonistic antibodies against IgE; it is safe and easy to use and might serve as a therapeutic antigen for hay fever and PFAS.

Tirbanibulin 1% Ointment for Actinic Keratosis: Results from a Real-Life Study.

Background and Objectives: Tirbanibulin 1% ointment is a novel synthetic anti-proliferative agent that inhibits tubulin polymerization. It is approved for treating actinic keratosis (AK) on the face and scalp in adults. It has demonstrated good efficacy, an adequate safety profile and excellent patient adherence in the phase 3 clinical trials, however data about its real-life efficacy and safety are lacking. Here we report the experience of the dermatology unit of the University Hospital of Messina. Materials and Methods: We performed a spontaneous open-label, prospective non-randomized study to assess the effectiveness and safety of tirbanibulin 1% ointment for the treatment of 228 AKs in 38 consecutive patients-28 males (73%) and 10 females (26%)-aged between 52 and 92 years (mean age: 72 ± 8.92 years). Results: Total clearance was recorded in 51% of lesions, while partial clearance was recorded in 73% of lesions. An excellent tolerability profile and high compliance rate were observed, with no treatment discontinuation due to the onset of adverse events. Conclusion: Our real-life experience confirms the effectiveness and safety of tirbanibulin ointment for the treatment of AKs.

[Randomized,double-blind,parallel controlled,multicenter clinical trial of effectiveness and safety of Shexiang Zhuifeng Zhitong Ointment in alleviating pain in knee osteoarthritis(syndrome of cold-dampness obstruction)].

The Shexiang Zhuifeng Zhitong Ointment with the effects of dispelling wind, removing dampness, dissipating cold, and relieving pain is used for treating arthralgia, muscular pain, and sprain pain caused by cold-dampness obstruction. To evaluate the efficacy and safety of Shexiang Zhuifeng Zhitong Ointment in relieving the pain due to knee osteoarthritis(syndrome of cold-dampness obstruction), a randomized, double-blind, parallel controlled, multicenter clinical trial was conducted. The stratified randomization method was used to randomize the 240 subjects into a treatment group and a control group in a ratio of 1∶1. In each group, 60 patients received external application for 12 h and the other 60 patients received external application for 6 h. The treatment group received external application of Shexiang Zhuifeng Zhitong Ointment, while the control group received external application of Shexiang Zhuifeng Ointment. The treatment lasted for 21 days in both groups. Follow-up was conducted on days 7, 14, and 21 of treatment. The results based on the full analysis set were as follows.(1)In visual analog scale(VAS) score, the mean difference in the VAS score between baseline and 12 h post-treatment was 3.02 in the treatment group and 2.31 in the control group, with a significant difference(P<0.05). The mean difference in the VAS score between baseline and 6 h post-treatment was 3.19 in the treatment group and 2.48 in the control group, with a significant difference(P<0.05).(2)Response rate in terms of VAS score, after treatment for 12 h, the response rate was 93.22% in the treatment group and 73.33% in the control group, with a significant difference(P<0.05). After treatment for 6 h, theresponse rate in the treatment group was 88.33%, which was higher than that(63.33%) in the control group(P<0.05).The results showed that Shexiang Zhuifeng Zhitong Ointment applied for 12 and 6 h effectively relieved the knee joint pain of patients with knee osteoarthritis due to cold-dampness obstruction, as demonstrated by the reduced VAS score, Western Ontario and McMaster Universities Arthritis Index(WOMAC), stiffness, and joint function score. Moreover, Shexiang Zhuifeng Zhitong Ointment outperformed the positive control Shexiang Zhuifeng Ointment in terms of reducing the VAS score, demonstrating a definitetherapeutic effect on the pain due to knee osteoarthritis(syndrome of cold-dampness obstruction).In addition, Shexiang Zhuifeng Zhitong Ointment did not cause other adverse reactions except for mild allergic reactions, which were common in the external application of traditional Chinese medicine plasters on the skin, inseveral patients.Neither other adverse reactions nor abnormalities of liver and kidney functions and electrocardiogram were observed. This ointment had high safety and could be popularized in clinical application.

Impact of Apparatus and Adapter on In vitro Drug Release of Ophthalmic Semisolid Drug Products.

PURPOSE: In vitro release testing (IVRT) is a widely used tool for evaluating the quality and performance of drug products. However, standardized sample adaptors or drug release apparatus setups for IVRT studies are still lacking for ophthalmic ointments. The aim of this study was to provide a better understanding of the impact of apparatus and sample adaptor setups on IVRT of ophthalmic ointments. METHODS: Dexamethasone (DEX), a steroidal ingredient commonly used in ophthalmic drug products, was selected as a model drug. Ointments were prepared by mixing DEX in white petrolatum using a high shear mixer. A novel two-sided adapter was developed to increase the drug release surface area. DEX ointment was placed in one-sided or two-sided release adaptors coupled with 1.2 µm polyethersulfone membrane, and the drug release was studied in different USP apparatuses (I, II, and IV). RESULTS: The sample adaptor setups had a minimal impact on cumulative drug release amount per area or release rate while USP IV apparatus with agitated flow enhanced drug release rates. The USP apparatus I with a two-sided semisolid adapter, which uses membranes on both sides, showed dramatically higher cumulative drug release and discriminative release profiles when evaluating ophthalmic formulations. CONCLUSIONS: USP apparatuses and sample adaptors are critical considerations for IVRT. Two-sided semisolid adapter provides higher cumulative release, facilitating the discrimination between low drug content ophthalmic ointment formulations with good sensitivity and repeatability without affecting the drug release rate.

Clinical Outcomes of Medical Management Options for Chronic Anal Fissures in a Long-Term Follow-up: Systematic Review and Meta-Analysis.

BACKGROUND: Topical treatments and botulinum toxin injections are valid options for the management of patients with chronic anal fissures (CAF), but little is known about the efficacy of these techniques in long-term follow-up. The aim of this meta-analysis was to evaluate the effectiveness, given to clinical outcomes, of medical treatments with calcium antagonists, nitroglycerin, and botulinum toxin on CAF treatment in adults. METHOD: A systemic review and meta-analysis developed according to PRISMA [PLoS Med. 2009 Jul 21;6(7):e1000100; BMJ. 2010 Mar 23;340:c332] and registered in PROSPERO (Registration number: CRD42020120386). A systematic literature search was conducted through MEDLINE, EMBASE, Web of Science, and Cochrane Library databases. Randomized control trials that compared medical treatment were identified; publications had to have a clinical definition of CAF with at least one of the following signs or symptoms: visible sphincter fibers at the base of the fissure, anal papillae, sentinel piles, and indurated margins. The symptoms had to be chronic for at least 4 weeks. Data were independently extracted for each study, and a meta-analysis was drawn using fixed- and random-effects models. RESULTS: 17 randomized trials met the inclusion criteria. Diltiazem showed a superior effect compared with glycerin (RR = 1.16 [95% CI = 1.05-1.30]; I2 = 18%) and with fewer adverse effects (RR = 0.13 [95% CI = 0.04-0.042]; I2 = 87%). Similar results were evidenced with the use of nifedipine compared with lidocaine (RR = 4.53 [95% CI = 2.99-6.86]; I2 = 28%). Botulinum toxin did not show statistically significant differences compared to glycerin (RR = 0.81 [95% CI = 0.02-29.36]; I2 = 93%) or isosorbide dinitrate (RR = 1.45 [95% CI = 0.32-6.54]; I2 = 85%). Regarding recurrence, nifedipine was superior to lidocaine (RR = 0.18 [95% CI = 0.08-0.44]; I2 = 31%). CONCLUSIONS: Calcium channel blockers performed well regarding the healing of CAF when compared to others in long-term follow-up. The superiority of botulinum toxin was not evidenced compared to topical treatments. More studies are needed to better assess recurrence rates.

Cellulitis caused by Roseomonas mucosa in a child: a case report.

BACKGROUND: Roseomonas mucosa (R. mucosa) is a pink-pigmented, Gram-negative short rod bacterium. It is isolated from moist environments and skin, resistant to multiple drugs, including broad-spectrum cephalosporins, and a rare cause of infection with limited reports. R. mucosa mostly causes catheter-related bloodstream infections, with even fewer reports of skin and soft tissue infections. CASE PRESENTATION: A 10-year-old boy received topical steroid treatment for sebum-deficient eczema. A few days before the visit, he was bitten by an insect on the front of his right lower leg and scratched it due to itching. The day before the visit, redness, swelling, and mild pain in the same area were observed. Based on his symptoms, he was diagnosed with cellulitis. He was treated with sulfamethoxazole/trimethoprim, and his symptoms improved. Pus culture revealed R. mucosa. CONCLUSIONS: We report a rare case of cellulitis caused by R. mucosa. Infections caused by rare organisms that cause opportunistic infections, such as R. mucosa, should be considered in patients with compromised skin barrier function and regular topical steroid use. Gram stain detection of organisms other than Gram-positive cocci should be considered.

Crisaborole reverses dysregulation of the mild to moderate atopic dermatitis proteome toward nonlesional and normal skin.

BACKGROUND: Safe and effective long-term topical treatments for atopic dermatitis (AD) remain limited. OBJECTIVE: In this phase 2a, single-center, intrapatient, and vehicle-controlled study, we examine the mechanism of action of crisaborole 2% ointment, a topical nonsteroidal PDE4 (phosphodiesterase-4) inhibitor, in a proteomic analysis of 40 adults with mild to moderate AD and 20 healthy subjects. METHODS: Within the AD cohort, 2 target lesions were randomized in an intrapatient (1:1) manner to double-blind crisaborole/vehicle applied twice daily for 14 days. Punch biopsy specimens were collected for biomarker analysis at baseline from all participants, then from AD patients only at day 8 (optional) and day 15. RESULTS: Compared to the vehicle, crisaborole significantly reversed dysregulation of the overall lesional proteome and of key markers and pathways (eg, Th2, Th17/Th22, and T-cell activation) associated with AD pathogenesis toward both nonlesional and normal skin. Significant clinical correlations were observed with markers associated with nociception and Th2, Th17, and neutrophilic activation. LIMITATIONS: Study limitations include predominance of white patients in the cohort, relatively short treatment time, and regimented administration of crisaborole. CONCLUSION: Our results demonstrate crisaborole-induced normalization of the AD proteome toward a nonlesional molecular phenotype and further support topical PDE4 inhibition in the treatment of mild to moderate AD.

Evaluation of the additional prophylactic effect of topical steroid ointment to systemic minocycline against anti-epidermal growth factor antibody-induced skin toxicities in metastatic colorectal cancer treatment.

BACKGROUND: Anti-epidermal growth factor receptor (EGFR) antibodies often cause skin toxicities. Preemptive skin treatments using systemic antibiotics with or without topical steroid are reportedly effective although the most suitable method remains unclear. This study aimed to determine whether combination prophylaxis using systemic minocycline and topical steroid is superior to minocycline alone in a real-world metastatic colorectal cancer (mCRC) treatment. METHODS: Patients with mCRC (n = 87) who received anti-EGFR monoclonal antibodies were retrospectively assessed. The primary objective was to compare the incidence of grade ≥ 2 overall skin toxicities during all treatment periods between the control group receiving prophylactic minocycline 100 mg/day, and the combination prophylaxis group receiving minocycline 100 mg/day + topical steroid. The incidence of each skin symptom was also evaluated. RESULTS: The incidence of grade ≥ 2 overall skin toxicities was 63.6% in the control and 56.9% in the combination groups, with no significant difference (P = 0.63). Similarly, the incidence of grade ≥ 2 dry skin, fissures, paronychia, and pruritus did not significantly differ. In addition, incidence of all-grade skin toxicities was not different. However, the incidence of grade ≥ 2 papulopustular rashes was significantly lower in the combination group (23.1% vs. 50.0%, P = 0.03). Propensity score-matched analysis supported these results. Multivariate logistic regression analysis showed no significant association between combination prophylaxis and grade ≥ 2 overall skin toxicities, but it did show a reduction in grade ≥ 2 papulopustular rashes. CONCLUSION: Adding topical steroids to systemic minocycline did not mitigate grade ≥ 2 overall skin toxicities induced by anti-EGFR antibodies; however, it significantly improved papulopustular rashes.

Analgesic Effect of Topical Piroxicam vs Phytotherapy Gel in the Treatment of Acute Soft Tissue Injuries: A Randomized Controlled Noninferiority Study.

OBJECTIVE: The study compared the efficacy and tolerability of piroxicam gel and a new topical combination of medicinal plant products (Soulagel®; Belpharma Tunisia) to treat pain caused by soft tissue injuries. METHODS: Patients (n = 1,525) were assigned to receive piroxicam gel or Soulagel. Efficacy assessments included a change of at least 50% in the pain-on-movement visual numeric scale rating from emergency department discharge (baseline) to day 7 final assessment, as well as the time required to reach pain resolution criteria, the need for rescue analgesia, patients' satisfaction, and the rate of adverse effects. RESULTS: At day 7, 1,216 patients (79.7%) achieved at least 50% reduction in visual numeric scale rating from baseline: 623 patients (82.4%) in the Soulagel group vs 593 patients (77.1%) in the piroxicam group (P = 0.01). Time to decrease pain on movement by 50% was significantly higher with piroxicam gel than with Soulagel (34 ± 1 vs 33 ± 1 days, respectively; P = 0.54). At day 7, 96.4% of patients in the Soulagel group declared being "very satisfied" to "satisfied," vs 68% in the piroxicam group (P < 0.001). There were no major adverse events in either group. CONCLUSIONS: Soulagel is not inferior to piroxicam gel for managing pain related to a soft tissue injuries. Further studies will help ascertain whether this new gel offers an alternative treatment option for this common emergency department condition.

Effect of Ointment Base on the Skin Wound-Healing Deficits in Streptozotocin-Induced Diabetic Rat.

Wound-healing deficits of the skin, one of the most common complications in patients with diabetes, delay wound healing, significantly reducing the patient's QOL. Therefore, the topical treatment of wound areas with drug-containing ointments and dressings is important. In this study, we investigated the effect of various ointment bases on skin wound healing in normal and streptozotocin-induced diabetic rats (STZ rats). Three ointment bases were used: white ointment (oil-based), absorbent cream (emulsion-based, w/o), and macrogol ointment (water-based). Skin wound healing in STZ rats was delayed compared with that in normal rats. Each of the three ointment bases was applied to the skin wound area in normal rats, and there was no difference in the therapeutic effect. The therapeutic effect of both white ointment and absorbent cream was higher in the STZ rats group than that in the non-treated group, and delayed wound healing was observed in STZ rats treated with macrogol ointment. In conclusion, skin wound healing in STZ rats is affected by the properties of the ointment base, and it is important to use an ointment base that controls the drying of the wound area in STZ rats. These findings provide information for the selection of ointment bases useful for application to skin wounds in patients with diabetes.
