A comparative evaluation of the effects on postoperative pain of systemic and topical forms of benzydamine hydrochloride after periodontal flap surgery: A randomized controlled clinical trial

Objective: The aim of this study was to evaluate comparatively the topical and systemic forms in the postoperative pain control periodontal flap surgery in spite of the daily dose of benzydamine hydrochloride spray form about one in twenty of the oral dose,. Materials and Methods: In this randomized trial, the 48 systemic healthy individuals in need double-blind study with periodontal flap surgery were evaluated. Consent, demographic information and periodontal clinical parameters were obtained before surgery and periodontal flap surgery was performed with local anesthesia. The patients who underwent surgery were randomly assigned to two groups. One of the groups was prescribed tablet form of postopertive benzydamine hydrochloride and for the other was spray form as topical application. Postoperative pain was assessed by visual analog scale at 2, 6, 8, 12, 24 and 48 hours. Results: There was no difference between systemic and topical drug groups in terms of demographic characteristics and periodontal clinical parameters. A statistically significant difference was found between 2 and 6 hours in favor of topical application. (p <0.05), but there was no significant difference in pain intensity at the 8th, 12th, 24th and 48th hours. Conclusion: Although the topical form of benzydamine hydrochloride was 1/20 lower in postoperative pain control after periodontal flap surgery, it was found to be more effective in the early period compared to the systemic form, but equally effective in the late period. We premierly recommend that topical application should be preferred primarily in the prevention of overdose and toxicity in postoperative pain control after periodontal flap operation.

Utility and Acceptability of Perskindol Spray and Gel as a Topical Treatment for Musculoskeletal Pain

Perskindol (study treatment) is a topical pain treatment in gel or spray form which contains menthol and herbal components. These two open-label, prospective, nonrandomized monadic studies in the Philippines and Thailand investigated the utility and acceptability of the study treatment for musculoskeletal pain. Adults with musculoskeletal pain were advised to use the study gel or spray as needed for up to 7 days. Their usage, perceptions, and response to treatment were assessed by patient diary and structured questionnaire. At study end, patients from both studies generally rated the study treatment higher in terms of ease of use, onset, and duration of pain relief, low potential for skin irritation and overall rating compared with their previous treatment. Differentiation analysis showed that the study treatment addressed patient preferences perceived as important, which were rapid relief of pain and ease of use. These findings suggest that the study spray and gel are useful and acceptable topical treatments for musculoskeletal pain and may be considered in self-directed pain management.

Vitamin D3supplementation in healthy adults: a comparison between capsule and oral spray solution as a method of delivery in a wintertime, randomised, open-label, cross-over study

Vitamin D is typically supplied in capsule form, both in trials and in clinical practice. However, little is known regarding the efficacy of vitamin D administered via oral sprays – a method that primarily bypasses the gastrointestinal absorption route. This study aimed to compare the efficacy of vitamin D3liquid capsules and oral spray solution in increasing wintertime total 25-hydroxyvitamin D (25(OH)D) concentrations. In this randomised, open-label, cross-over trial, healthy adults (n22) received 3000 IU (75 µg) vitamin D3daily for 4 weeks in either capsule or oral spray form. Following a 10-week washout phase, participants received the opposite treatment for a final 4 weeks. Anthropometrics and fasted blood samples were obtained before and after supplementation, with samples analysed for total 25(OH)D, creatinine, intact parathyroid hormone and adjusted Ca concentrations. At baseline, vitamin D sufficiency (total 25(OH)D>50 nmol/l), insufficiency (31–49 nmol/l) and clinical deficiency (<30 nmol/l) were evident in 59, 23 and 18 % of the participants, respectively. Overall, baseline total mean 25(OH)D concentration averaged 59·76 (sd29·88) nmol/l, representing clinical sufficiency. ANCOVA revealed no significant difference in the mean and standard deviation change from baseline in total 25(OH)D concentrations between oral spray and capsule supplementation methods (26·15 (sd17·85)v. 30·38 (sd17·91) nmol/l, respectively;F=1·044, adjustedr20·493,P=0·313). Oral spray vitamin D3is an equally effective alternative to capsule supplementation in healthy adults.

Efficacy of Lignocaine in Gel and Spray form during Buccal Infiltration Anesthesia in Children: A Randomized Clinical Trial

ABSTRACT Aim To compare the efficacy of 15% lignocaine spray and 8% lignocaine gel as a topical anesthetic, in reducing pain, during buccal infiltration in children. Materials and methods Forty-two patients aged between 7 and 12 years requiring restorative procedures/extraction/pulp therapy of primary/ permanent teeth in the maxillary arch, under buccal infiltration anesthesia were selected for the study. The participants were randomly allocated into 2 groups of 21 each. In group A, 8% lignocaine gel and in group B, 15% lignocaine spray was applied prior to buccal infiltration. Pain was assessed using Wong-Baker faces pain rating scale (WBFPRS) and faces legs activity cry and consolability (FLACC) painscale. Results Pearson's chi-square test revealed that there was no significant difference in the FLACC scores of the two groups (p = 0.54). Independent t-test demonstrated that there was no significant difference in Wong-Bakers faces pain score between the two agents (p = 0.07). Conclusion There is no significant difference in the efficacy of 15% lignocaine spray and 8% lignocaine gel as a topical anesthetic in controlling pain during buccal infiltration anesthesia, in children.

Inhibition of Mold Growth and Mycotoxin Production in High-Moisture Corn Treated with Phosphates

Mold growth and mycotoxin production were studied in high-moisture (20%) corn treated with tetrasodium pyrophosphate (TSPP); acid and alkaline sodium polyphosphate, glassy (SPG), also known as sodium hexametaphosphate; sodium tripolyphosphate (STPP); and tricalcium phosphate. Six mold cultures belonging to the genera Aspergillus, Fusarium, and Penicillium were tested in corn varieties highly resistant or highly susceptible to mold infection in the field, and in a mixture of five other varieties of corn. The acidic SPG, as well as TSPP and STPP totally prevented or reduced mold growth when added in powder form to corn at 1.0% or 2.0% (w/w), regardless of corn variety and high moisture content. Phosphates afforded protection in whole and damaged kernels. Similar results were obtained with 2.0% acidic SPG and TSPP when added in spray form. Whenever mold growth occurred, treatment of corn with 1.0% or 2.0% (w/w) TSPP and acidic or alkaline SPG inhibited (P&lt;0.01) aflatoxin production by aspergilli.

2% Miconazole Nitrate Powder in Aerosol Spray Form: Its Efficacy in Treating Tinea Pedis

Forty-six patients with acute tinea pedis were treated with either 1% tolnaftate aerosol spray powder or 2% miconazole nitrate aerosol spray powder, not previously available. Products were coded, and the study was conducted in a double-blind manner. At the end of 28 days of therapy, 68% of the miconazole-treated group achieved therapeutic cure, versus 50% in the tolnaftate-treated group. Symptomatic relief and mycological clearing based on potassium hydroxide examination took place in less time for the patients treated with miconazole nitrate. The aerosol spray powder form is an effective alternative vehicle to both cream and solution.

Herbicides Applied as Liquid Sprays and Granules for Weed Control in Cotton

We evaluated the effectiveness of aqueous sprays and granules of 3-(3,4-dichlorophenyl)-1,1-dimethylurea (diuron), 1,1-dimethyl-3-(α,α,α-trifluoro-m-tolyl)urea (fluometuron), isopropylm-chlorocarbanilate (chlorpropham), α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin), and 2-chloro-2′, 6′-diethyl-N-(methoxymethyl) acetanilide (alachlor) incorporated shallow for weed control in cotton(Gossypium hirsutumL., var. Stoneville 7A). In general, liquid formulation provided better weed control than did granular formulation. Applications of alachlor resulted in good weed control, but in a dry season the liquid spray form of the herbicide at high rates reduced the yield of cotton.
