BACKGROUND
An important trend in the personal care industry involves the development of body wash products that not only clean the skin without damage but deposit conditioning ingredients to improve skin barrier function.
OBJECTIVE
The objective of this study was to develop skin biomarker measures to quantify the treatment effects of body wash products.
METHODS
We employed analysis of structural proteins (keratin 1,10,11 and involucrin), a natural moisturizing factor (pyrrolidone carboxylic acid) and an inflammatory mediator (IL-1ra/IL-1α) from adhesive discs with dry skin grading, TEWL and capacitance measurements to compare the effects of direct application of petrolatum, a high petrolatum depositing body wash, and a regular body wash on dry leg skin in a standard leg-wash treatment protocol.
RESULTS
High depositing body wash and petrolatum had positive effects on stratum corneum barrier function as judged by biomarker analysis, biophysical measurements and skin grading compared to the regular body wash product.
CONCLUSIONS
The results clearly indicate that a combination of biomarker and biophysical property measurements is effective for determining the skin benefits of moisturizing body wash products.

Comparative Study
Excipients from different sources may lead to significant differences in the performance of drug products, posing challenges in product quality control. A previous report showed that the drug release rates from ophthalmic ointments were affected by source variation of white petrolatum. To understand the physicochemical properties including the microstructure of white petrolatum and the impact of this on the performance of finished products, the following were investigated: rheological properties, thermal analysis (differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA)), as well as structural characteristics (polarized light microscopy (PLM), small-angle X-ray scattering (SAXS) and wide-angle X-ray scattering (WAXS)). The rheological parameters may be indicative of the drug release rate of the finished ophthalmic ointments when using a process involving hot-melting with immediate cooling. The white petrolatum from the four different sources also showed different thermal behavior. According to SAXS and WAXS, all of the petrolatum showed semi-crystalline behavior with different extents of crystallinity (from 9.5% to 16.9%). The crystalline domains of the petrolatum are ordered in an orthorhombic structure forming lamellar sheets with a periodicity from 9.1 nm to 9.9 nm. An in-depth understanding of the semi-crystalline structure was obtained and it provided valuable information for formulation optimization and characterization of petrolatum-based products.

Review
INTRODUCTION
Up to 9% of children may have recurrent nosebleeds, usually originating from the anterior septum, but the majority grow out of the problem.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for recurrent idiopathic epistaxis in children? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2013 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 5 systematic reviews or RCTs that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: antiseptic cream (containing chlorhexidine hydrochloride, neomycin sulfate, or both), petroleum jelly, and silver nitrate cautery.

Petrolatum ointment, which is an oleaginous ointment, is generally produced through manufacturing processes such as melting, mixing, and cooling. In this type of semisolid formulation, the manufacturing conditions of each process are empirically known to affect the quality of the resultant preparation; however, in many cases, the details of the factors are unclear. To clearly investigate the influence of the pharmaceutical properties of petrolatum ointments, we manufactured several ointments while changing the conditions of the mixing and cooling process after melting white petrolatum. As a result, the temperature at the termination was determined to influence the pharmaceutical properties of the final product. To investigate these phenomena, each petrolatum ointment sample was examined via digital microscopy and laser Raman analysis, and the distribution of the liquid-solid parts of samples was investigated. The internal structure of the ointment sample manufactured at a mixing-stop temperature of 40 °C, the needle crystals and the spherical aggregates surrounding them appropriately coexisted, while the structure exhibited a state wherein the two were linked in a semisolid phase. Meanwhile, for the ointment sample manufactured under the lowest mixing-stop temperature of 25 °C, the liquid part and the spherical aggregates were clearly separated, indicating that the liquid part was easily separated from ointments. In addition, the distribution of the hydrocarbons among the samples was measured via GC-MS; no significant difference in chemical structure was observed. In conclusion, the internal structure of the petrolatum ointment was changed by the manufacturing conditions, and this affected the pharmaceutical properties.

Comparative Study
White petrolatum is frequently used as an oleaginous base, but has a drawback of poor usability. In this trial, white petrolatum was prepared at a lower melting point to improve its usability. Characteristic pharmaceutical values such as melting point, yield, and consistency were compared between a conventional product and ophthalmic white petrolatum. Usability was compared by administering a survey questionnaire and evaluating the comparable moisturizing effect by conductivity in humans. The melting point and yield value of the improved product were significantly lower compared with other white petrolatum products. In the survey, the improved product was rated excellent in five criteria. On a scale of 1 to 5, the average values for the five criteria for the improved product were 4.7, while the conventional product and ophthalmic white petrolatum were rated 3.0 and 3.5, respectively. No difference in moisturizing effect was observed among all petrolatums after application, from day 1 to day 14. In conclusion, the improved white petrolatum demonstrated better usability, and the moisturizing effect was equivalent to conventional product, suggesting that the use of this improved product may lead to improved adherence.

Petrolatum is a mixture of hydrocarbons that is widely used as a moisturizer. It is incorporated in bodywash formulations to help hydrate and maintain healthy skin appearance. The aim of this study was to investigate skin deposition and penetration of petrolatum from an experimental bodywash system consisting of petrolatum . Experiments were performed using cadaver split-thickness skin and Franz diffusion cells. Radiolabeled C-dotriacontane (C-alkane) was used as a model permeant for petrolatum. The bodywash was applied on the skin and subsequently rinsed. At predetermined time points, the skin was wiped to remove the residual material on the surface, and tape-stripping was performed. Petrolatum was observed to deposit from the bodywash when applied on split-thickness skin with simulated rinsing. Petrolatum then penetrated into the stratum corneum and was detected at the depth of 12 tape-stripping and in the epidermis. The bodywash formulation could provide significant deposition and penetration of petrolatum into the stratum corneum at 1-72 hours postapplication.

Randomized Controlled Trial
Topical petrolatum gel alone versus topical silver sulfadiazine with standard gauze dressings for the treatment of superficial partial thickness burns in adults: a randomized controlled trial.
BACKGROUND
Non-extensive superficial partial thickness burns constitute a major proportion of burns. Conventional treatment involves regular changing of absorptive dressings including the application of a topical antimicrobial, commonly silver sulfadiazine. A systematic review has found insufficient evidence to support or refute such antimicrobial prophylaxis. Another review compared silver sulfadiazine dressings with other occlusive and non-antimicrobial dressings and found insufficient evidence to guide practice. Other research has suggested that dressings with petrolatum gel are as effective as silver sulfadiazine.
METHODS
Single-center, randomized, controlled parallel group trial comparing conventional silver sulfadiazine dressings with treatment with petrolatum gel alone. Consenting adults 18-45 years old with superficial partial thickness burns≤10% total body surface area seen within 24h of the injury were randomized to daily dressing either with petrolatum gel without top dressings or conventional silver sulfadiazine treatment with gauze dressings. Primary outcomes were blinded assessment of time to complete re-epithelialization, wound infection or allergic contact dermatitis. Secondary outcomes included assessment of ease, time and pain of dressing changes.
RESULTS
26 patients were randomized to petrolatum and 24 to silver sulfadiazine dressings. Follow up data available for 19 in each group. Mean time to re-epithelialization was 6.2 days (SD 2.8) in the petrolatum group and 7.8 days (SD 2.1) in the silver sulfadiazine group (p=0.050). No wound infection or dermatitis was observed in either group. Scores for adherence to wound, ease of dressing removal and time required to change dressings were significantly better in the petrolatum treatment arm (p<0.01).
CONCLUSIONS
Petrolatum gel without top dressings may be at least as effective as silver sulfadiazine gauze dressings with regard to time to re-epithelialization, and incidence of infection and allergic contact dermatitis. Petrolatum gel appears to be an effective, affordable and widely available alternative in the treatment of minor superficial partial thickness burns in adults.

Clinical Trial Comparative Study Randomized Controlled Trial
Various agents which can be used in combination can also interfere with phototherapy. In this study, the effects of topical petrolatum and 20% salicylic acid in petrolatum upon skin photoreaction to UVA were investigated, in an in vivo test. Minimal phototoxic dose (MPD) test was performed on 31 volunteers and the test was repeated with thin (0.1 cc/25 cm(2)) petrolatum, thick (0.3 cc/25 cm(2)) petrolatum, thin 20% salicylic acid in petrolatum, thick 20% salicylic acid in petrolatum and sunscreen. The effect of each agent on MPD was investigated. MPD was increased with thin and thick applications of all agents. Also, MPD was increased with 20% salicylic acid in petrolatum when compared with pure petrolatum, in the same thickness. The application of petrolatum and salicylic acid in petrolatum just before PUVA therapy is not recommended because of their blocking effects.
