Comparative Study
PURPOSE
To evaluate the effect of CPP-ACPF paste and fluoride toothpastes on enamel subjected to erosion and erosion plus abrasion in vitro.
MATERIALS AND METHODS
A total of 220 human enamel blocks were divided into eleven groups (n = 20): CPP-ACPF paste (MPP), potassium nitrate/sodium fluoride toothpaste (PE), sodium fluoride toothpaste (FD), fluoride-free toothpaste (SO) and control (erosion only with no paste or toothpastes; CO) according to the experimental design: erosion or erosion plus abrasion immediately after erosion (ERO+I-ABR) or 30 min after erosion (ERO+30min-ABR). For 5 days, the specimens were subjected to: (1) erosive challenge (EC) (cola drink, 4 x 5 min/day), topical application of the undiluted paste or diluted toothpastes (1:2 w/w) (4 x 1 min/ day) plus 1 h in artificial saliva (AS) between cycles and overnight; or (2) EC plus abrasion (4 x /60 s/day) performed with the diluted toothpastes (no MMP) plus 1 h in AS between cycles and overnight. Erosion depth was quantified through a 3D profilometer. Data were analysed using Kruskal-Wallis, Mann-Whitney and Wilcoxon tests (p = 0.05).
RESULTS
CPP-ACPF paste and NaF toothpaste showed lowest enamel wear among groups and reduced tissue loss by 89% in erosion challenge. Abrasion led to higher enamel wear than erosion only (p = 0.030). ERO+30min-ABR had no protective effect when compared to ERO+I-ABR (p > 0.05).
CONCLUSION
A high frequency of CPP-ACPF paste application (4x daily) is effective in reducing the effects of erosion. A waiting period before performing toothbrushing does not protect enamel against erosion regardless the composition of the toothpastes.

One of the skin's principal functions is to protect the body against its environment by maintaining an effective epidermal barrier, not only against external factors, but also to prevent water loss from the body. Indeed, water homeostasis is vital for the normal physiological functioning of skin. Hydration levels affect not only visible microscopic parameters such as the suppleness and softness of skin, but also molecular parameters, enzyme activities and cellular signalling within the epidermis. The body is continually losing some of its water, but this phenomenon is limited and the optimal hydration gradient in skin is ensured via a set of sophisticated regulatory processes that rely on the functional and dynamic properties of the uppermost level of the skin consisting of the stratum corneum. The present article brings together data recently acquired in the fields of skin hydration and the characterisation of dehydrated or dry skin, whether through study of the regulatory processes involved or as a result of changes in the techniques used for in situ measurement, and thus in optimisation of management.

The objective of this study was to investigate the stability of compounded nifedipine cream in gel and ointment formulations dispensed in white plastic and glass amber jars. Extemporaneously compounded nifedipine cream (Glaxal Base), gel (K-Y Jelly), and ointment (Aquaphor) in white plastic and glass amber jars were stored at 4°C, 23°C, and 40°C. We determined potency on days 0, 7, 14, 30, 60, and 90, and subsequently assigned beyond-use-dates based on United States Pharmacopeia recommendations, organoleptic properties, and pH changes. Nifedipine potency in cream and ointment stored in white plastic jars was within ±10% of initial for 90 days (excluding day 14 for cream). In glass amber jars, potency was outside the acceptable range by day 14 at 23°C but within range for 90 days at 4°C (excluding day 30). Nifedipine potency was maintained for 90 days in both jars at 23°C and 4°C (excluding day 30) and in white plastic jars at 40°C, but 60 days stored in glass amber jars. The pH of formulations was stable with changes of less than 1-unit pH. At 40°C, a significant decrease in apparent viscosity of cream was evident on day 90. There was a decrease in apparent viscosity and phase separation of the ointment at 40°C and an increase in apparent viscosity (difficult to mix) at 4°C on day 14 onwards. Significant organoleptic changes were observed by day 7 at 40°C (decrease in apparent viscosity and abnormal odor by day 90), day 30 at 4°C (thicker consistency), and day 90 at 23°C (abnormal odor). Storage in white plastic jars at 23°C is recommended for compounded topical nifedipine cream and ointment (for 90 days), and for gel (60 days).

Review
BACKGROUND
Electrochemotherapy is a novel treatment for cutaneous and subcutaneous tumors utilizing the combination of electroporation and chemotherapeutic agents. Since tumors have an increasing incidence nowadays as a result of environmental and genetic factors, electrochemotherapy could be a promising treatment for cancer patients.
OBJECTIVE
The aim of this article is to summarize the novel knowledge about the use of electroporation for antitumor treatments and to present a new application of electrochemotherapy with a well-known plant derived antitumor drug betulinic acid. For the review we have searched the databases of scientific and medical research to collect the available publications about the use of electrochemotherapy in the treatment of various types of cancer.
METHOD
By the utilization of the available knowledge, we investigated the effect of electroporation on the penetration of a topically applied betulinic acid formulation into the skin by ex vivo Raman spectroscopy on hairless mouse skin.
RESULTS
Raman measurements have demonstrated that the penetration depth of betulinic acid can be remarkably ameliorated by the use of electroporation, so this protocol can be a possibility for the treatment of deeper localized cancer nodules. Furthermore, it proved the influence of various treatment times, since they caused different spatial distributions of the drug in the skin.
CONCLUSION
The review demonstrates that electrochemotherapy is a promising tool to treat different kinds of tumors with high efficiency and with only a few moderate adverse effects. Moreover, it presents a non-invasive method to enhance the penetration of antitumor agents, which can offer novel prospects for antitumor therapies.

Randomized Controlled Trial
BACKGROUND
To our knowledge, there are no trials comparing emollients commonly used for childhood eczema. We aimed to compare the clinical effectiveness and safety of the four main emollient types: lotions, creams, gels, and ointments.
METHODS
We did a pragmatic, individually randomised, parallel group, phase 4 superiority trial in 77 general practice surgeries in England. Children aged between 6 months and 12 years with eczema (Patient Orientated Eczema Measure [POEM] score >2) were randomly assigned (1:1:1:1; stratified by centre and minimised by baseline POEM score and age, using a web-based system) to lotions, creams, gels, or ointments. Clinicians and parents were unmasked. The initial emollient prescription was for 500 g or 500 mL, to be applied twice daily and as required. Subsequent prescriptions were determined by the family. The primary outcome was parent-reported eczema severity over 16 weeks (weekly POEM), with analysis as randomly assigned regardless of adherence, adjusting for baseline and stratification variables. Safety was assessed in all randomly assigned participants. This trial was registered with the ISRCTN registry, ISRCTN84540529.
FINDINGS
Between Jan 19, 2018, and Oct 31, 2019, 12 417 children were assessed for eligibility, 550 of whom were randomly assigned to a treatment group (137 to lotion, 140 to cream, 135 to gel, and 138 to ointment). The numbers of participants who contributed at least two POEM scores and were included in the primary analysis were 131 in the lotion group, 137 in the cream group, 130 in the gel group, and 126 in the ointment group. Baseline median age was 4 years (IQR 2-8); 255 (46%) participants were girls, 295 (54%) were boys; 473 (86%) participants were White; and the mean POEM score was 9·3 (SD 5·5). There was no difference in eczema severity between emollient types over 16 weeks (global p value=0·77), with adjusted POEM pairwise differences of: cream versus lotion 0·42 (95% CI -0·48 to 1·32), gel versus lotion 0·17 (-0·75 to 1·09), ointment versus lotion -0·01 (-0·93 to 0·91), gel versus cream -0·25 (-1·15 to 0·65), ointment versus cream -0·43 (-1·34 to 0·48), and ointment versus gel -0·18 (-1·11 to 0·75). This result remained unchanged following multiple imputation, sensitivity, and subgroup analyses. The total number of adverse events did not significantly differ between the treatment groups (lotions 49 [36%], creams 54 [39%], gels 54 [40%], and ointments 48 [35%]; p=0·79), although stinging was less common with ointments (12 [9%] of 138 participants) than lotions (28 [20%] of 137), creams (24 [17%] of 140), or gels (25 [19%] of 135).
INTERPRETATION
We found no difference in effectiveness between the four main types of emollients for childhood eczema. Users need to be able to choose from a range of emollients to find one that they are more likely to use effectively.

Randomized Controlled Trial
BACKGROUND
Shoulder-hand syndrome (SHS) refers to a syndrome causing sudden edema, shoulder pain and limited hand function. Qingpeng ointment, a kind of Tibetan medicine, can reduce swelling, relieve pain, tonify stagnation and clear the meridians, which is consistent with the pathological mechanism of SHS after stroke. Therefore, if clinical trials can be used to explore the effectiveness of Qingpeng ointment for the treatment of poststroke SHS and promote its application in clinical medicine, it may prove the specific significance for the treatment of poststroke SHS poststroke SHS.
OBJECTIVE
The aim of the study was to investigate the clinical efficacy and safety of Qingpeng ointment in the treatment of poststroke SHS and to provide an objective basis for a better therapeutic treatment for poststroke SHS.
METHODS
A prospective, randomized, controlled study was conducted. This study recruited 120 patients with poststroke SHS who met the inclusion criteria. They were randomized into the treatment group and the control group, with 60 patients allocated to each group. The treatment group received routine medical treatment and rehabilitative care after using the Qingpeng ointment, while the patients in the control group received only routine treatment without the ointment. All patients received clinical assessment with the Visual Analogue Scale (VAS), measurement of the range of motion (ROM) of the upper-limb joints, the Fugl-Meyer Assessment of Upper Extremity (FMA-U) and the Modified Barthel Index Score (MBI) before and after the whole treatment.
RESULTS
After 4 weeks of treatment, the VAS scores of both the groups decreased significantly (P <0.05), and the difference between the two groups was statistically significant (P < 0.05). No statistical significance was observed for the difference between the treatment group and control group in terms of the FMA-U and MBI scores and the forward bend, backward, outstretch, external rotation and pronation angles after treatment. The increases in the values of VAS, FMA-M and MBI in the treatment group were greater than those in the control group, and the difference was statistically significant (P < 0.05). The increases in the values of the forward bend, outreach and external rotation angles in the treatment group were greater than those in the control group, and the difference was statistically significant (P < 0.05).
CONCLUSION
The treatment group showed better results than the control group in terms of the relief of pain symptoms, the improvement of motor function and the improvement of the activities of daily living for patients with shoulder-hand syndrome after cerebral hemorrhage. Qingpeng ointment was found to be effective and safe for treating poststroke SHS.

OBJECTIVE
The aim of this study was to compare the in vitro intradentinal antimicrobial ability of the calcium hydroxide and tri-antibiotic pastes.
MATERIALS AND METHODS
Standard bovine dentin tubes were sterilized and then infected with Enterococcus faecalis by a new contamination protocol of great depths of dentin. The specimens were filled with the medications, divided into two test-groups: calcium hydroxide (Group 1) and tri-antibiotic (Group 2) pastes. After 15 days, the teeth were evaluated by microbiological culture and confocal laser scanning microscopy (CLSM) with viability dye assay LIVE/DEAD inside dentinal tubules. In experiment of culture, the bacterial collection of the dentin fragments was done for counting the colony-forming units.
RESULTS
The tri-antibiotic paste had a slightly greater antimicrobial effect; however, there was no statistical difference between the groups.
CONCLUSIONS
It was concluded that the tri-antibiotic paste and the calcium hydroxide paste exercise the same effect on intra-tubular decontamination against E. faecalis. So, due the multiples advantages, the calcium hydroxide paste can be the choice for dentinal decontamination in regenerative procedures.

Review
Crisaborole ointment 2% (Eucrisa™) is a novel, anti-inflammatory inhibitor of phosphodiesterase 4 (PDE4) that is available in the USA for the topical treatment of mild to moderate atopic dermatitis in patients aged ≥ 2 years. In two short-term (28 days), identically designed, multicentre, phase III studies in this patient population, topical therapy with crisaborole ointment 2% reduced disease severity and pruritus severity compared with vehicle, with the effect established early and sustained over the course of treatment. Improvements in the other signs of atopic dermatitis (erythema, exudation, excoriation, induration/papulation, and lichenification) were also seen. Crisaborole ointment 2% was generally well tolerated in the short-term studies, with its favorable safety profile maintained over the longer term (up to 52 weeks) in a multicentre, extension study. Most treatment-emergent adverse events (TEAEs) were of mild to moderate severity and considered unrelated to the study medication. Moreover, the incidence of application-site pain following short- and longer-term topical therapy with crisaborole ointment 2% was low. In conclusion, crisaborole ointment 2% is an effective and generally well tolerated new topical option for the management of mild to moderate atopic dermatitis in patients aged ≥ 2 years, with the potential to effectively treat this patient population over the longer term without the safety concerns associated with other current topical anti-inflammatory agents.

INTRODUCTION
Diabetic foot ulcers (DFUs) are slow to heal because of poor tissue vascularity and regenerative capacity, among various factors.
OBJECTIVE
In this study, the authors evaluate the efficacy of applying a paste formulation of acellular dermal matrix (ADM) to DFUs.
MATERIALS AND METHODS
Patients with Wagner grade 2 or 3 DFUs (N = 49) received either ADM paste (treatment group; n = 23) or conventional foam dressing (control group; n = 26). All chronic wounds were debrided and irrigated in an attempt to control infection. After paste application, mild compaction was undergone to fill ulcer cavities, and foam dressings were used to cover the surface to absorb any discharge. All DFUs were analyzed with regard to ulcer area, depth, progression, healing rate, and duration to complete healing.
RESULTS
At the 60-day primary outcome mark, 56.52% (13/23) of the DFUs in the treatment group were healed, compared with 23.08% (6/26) of DFUs in the control group. Mean rates of wound area resolution in the treatment and control groups were 74.17% ± 30.84% and 51.87% ± 32.81%, respectively (P ⟨ .05), with mean times to heal (within 60 days) of 13.54 ± 9.18 days and 21.5 ± 11.98 days, respectively (P ⟨ .05). There were no serious adverse events in either group, and no complications related to ADM paste application.
CONCLUSIONS
The ADM paste effectively enhanced tissue regeneration, shortening ulcer duration and preventing associated complications, while eliminating the need for supplemental ulcer management procedures. The paste formulation of ADM provides a matrix for tissue ingrowth, promoting the healing of DFUs.
