An alternative treatment for pityriasis versicolor, tinea cruris, tinea corporis and tinea faciei with topical application of honey, olive oil and beeswax mixture: an open pilot study

OBJECTIVE: To evaluate the possible role of honey, olive oil and beeswax in the treatment of skin fungal infections. PATIENTS AND METHODS: Thirty-seven patients with pityriasis versicolor, tinea cruris, tinea corporis and tinea faciei were studied. After clinical evaluation of redness, scaling, pruritis and burning/pain sensation and mycological assessment, honey mixture containing honey, olive oil and beeswax (1:1:1) was applied to the lesions three times daily for a maximum of 4 weeks. RESULTS: Clinical response was obtained in 86% of patients with pityriasis versicolor, 78% of patients with tinea cruris and in 75% of patients with tinea corporis. Mycological cure was obtained in 75, 71 and 62% of patients with PV, tinea cruris and tinea corporis, respectively. The patient with tinea faciei showed clinical and mycological cure 3 weeks after commencement of therapy. CONCLUSION: Honey mixture may have place in the management of these skin conditions and rigorous, controlled trials are justified.     

Disorders of T-cell immunity in patients with eczema, atopic dermatitis and psoriasis]

It is shown that patients suffering from eczema, atopic dermatitis and psoriasis demonstrate immunologic shifts related to genetic predisposition to allergic (atopic and autoimmune) responses, specific skin responses, clinical features of dermatoses, reactivity of the affected connective tissue. Immune defects of the above patients suggest a drop in T-lymphocyte count and T-suppressor dysfunction, i.e. T-cell immunodeficiency. This indicates possible benefit of pharmacological immunomodulators scheduled on the basis of pathogenetic characteristics of each variant of dermatosis and of dermal inflammation.     

Non-invasive skin biomarkers quantification of psoriasis and atopic dermatitis: Cytokines,antioxidants and psoriatic skin auto-fluorescence

Background

Psoriasis and atopic dermatitis (AD) are challenging to treat due to the absence of suitable monitoring procedure and their recurrences. Alteration of skin hydrophilic biomarkers (SHB) and structural elements occur in both disorders and may possess a distinct profile for each clinical condition.

Objective

To quantify skin cytokines and antioxidants non-invasively in psoriatic and in AD patients and to evaluate skin auto-fluorescence in psoriatic patients.

Methods

A skin wash sampling technique was utilized to detect the expression of SHB on psoriatic and AD patients and healthy controls. Inflammatory cytokine (TNFα, IL-1α and IL-6) levels, total antioxidant scavenging capacity and uric acid content were estimated. Additionally, measurement of the fluorescent emission spectra of tryptophan moieties, collagen cross-links and elastin cross-links were performed on psoriatic patients and healthy controls.

Results

Our findings demonstrate significant alterations of the SHB levels among psoriasis, AD and healthy skin. Differences were also observed between lesional and non-lesional areas in patients with psoriasis and AD. Ultra-structural changes were found in psoriatic patients both in lesional and non-lesional areas.

Conclusion

Employing non-invasive measurements of skin wash sampling and skin auto-fluorescence might serve as complementary analysis for improved diagnosis and treatment of psoriasis and AD. Furthermore, they may serve as an additional monitoring tool for various diseases, in which skin dysfunction is involved.     

Efficacy of acupuncture for migraine prophylaxis: a single-blinded, double-dummy, randomized controlled trial

Insufficient clinical trial data were available to prove the efficacy of acupuncture for migraine prophylaxis. A multicenter, double-dummy, single-blinded, randomized controlled clinical trial was conducted at the outpatient departments of acupuncture at 5 hospitals in China to evaluate the effectiveness of acupuncture. A total of 140 patients with migraine without aura were recruited and assigned randomly to 2 different groups: the acupuncture group treated with verum acupuncture plus placebo and the control group treated with sham acupuncture plus flunarizine. Treated by acupuncture 3 times per week and drugs every night, patients from both groups were evaluated at week 0 (baseline), week 4, and week 16. The primary outcome was measured by the proportion of responders (defined as the proportion of patients with a reduction of migraine days by at least 50%). The secondary outcome measures included the number of migraine days, visual analogue scale (VAS, 0 to 10 cm) for pain, as well as the physical and mental component summary scores of the 36-item short-form health survey (SF-36). The patients in the acupuncture group had better responder rates and fewer migraine days compared with the control group (P < .05), whereas there were no significant differences between the 2 groups in VAS scores and SF-36 physical and mental component summary scores (P > .05). The results suggested that acupuncture was more effective than flunarizine in decreasing days of migraine attacks, whereas no significantly differences were found between acupuncture and flunarizine in reduction of pain intensity and improvement of the quality of life.     

Paediatric atopic dermatitis: parameters of aetiology, diagnosis and management

Atopic dermatitis is not merely a skin condition. It can have a profound physical and psychological effect on the child and his/her family. This article discusses aetiology of the disease and describes appropriate management strategies.     

A randomized controlled pilot study comparing aqueous cream with a beeswax and herbal oil cream in the provision of relief from postburn pruritus

Postburn itch is reported to affect up to 87% of the burn population. Although treatments for postburn itch are multimodal, they remain consistently ineffective. However, recent anecdotal evidence from several outpatients at a tertiary referral hospital suggests that a cream combining beeswax and several herbal oils may be effective in the minimization of postburn itch. The aim of this study was to test the efficacy of beeswax and herbal oil cream against the standard treatment of aqueous cream in the provision of relief from the symptoms of postburn itch. A randomized controlled trial compared two groups using a visual analog scale, frequency of cream application, itch recurrence after cream application, use of antipruritic medications, and sleep disturbance to determine the effect of itch severity and duration. Fifty-two participants were enrolled in the study (84% male) with a mean age of 35 years (SD = 16) and mean burn TBSA of 7.2% (SD = 7.7). Study results found that the beeswax and herbal oil cream reduce itch after application more frequently than aqueous cream (P = .001). In addition, when managed with beeswax and herbal oil cream, participants found that their itch recurred later (P ≤ .001) and their use of antipruritic medications was lower (P = .023). Findings of this study suggest beeswax and herbal oil cream to be more effective in the minimization of postburn itch than aqueous cream. Given this, a larger study examining the efficacy of beeswax and herbal oil cream appears warranted.     

Classical conditioning and expectancy in placebo hypoalgesia: a randomized controlled study in patients with atopic dermatitis and persons with healthy skin

Provoked vestibulodynia is a common cause of superficial dyspareunia in young women. Recent evidence has pointed out the importance of studying endogenous pain modulation in these women. An impairment of diffuse noxious inhibitory controls (DNIC) has been suggested in chronic pain conditions with a female predominance such as fibromyalgia and temporomandibular disorder. Our aim was to examine whether patients with provoked vestibulodynia and healthy women with or without combined oral contraceptives (COC) display a DNIC response to cold noxious stimulation. Twenty patients with provoked vestibulodynia not using COC, 20 healthy women on COC and 20 healthy women without COC were included and tested days 7-11 of their menstrual cycle. Pressure pain thresholds (PPTs) and pain ratings using VAS were measured on the arm and leg before and during a cold pressor test. A socio-medical questionnaire, the Hospital and Anxiety Depression Scale and the Short Form-36 were completed. The majority of the subjects in all three study groups significantly increased their PPTs during cold noxious stimulation indicating a DNIC response. The patients displayed lower PPTs compared to the healthy women. Depression, anxiety and bodily pain were more often reported by the patients. No differences related to the intake of COC were observed between the healthy women. In conclusion, women with provoked vestibulodynia as well as healthy women irrespective of COC status display a DNIC response indicating an endogenous pain inhibition. However, the results imply a systemic hypersensitivity in women with vestibulodynia with low general pain thresholds as compared to healthy women.     

Dermatology for the internist: optimal diagnosis and management of atopic dermatitis

Internists are front-line health care providers that commonly provide the first encounter to patients for dermatological conditions, especially atopic dermatitis (AD). Internists need to be comfortable with managing mild-moderate AD in their practices. Criteria and guidelines established in dermatology literature are available to help the general practitioner diagnose and treat AD. AD is a systemic disease associated with multiple cutaneous and extra-cutaneous comorbidities that warrant screening by internists, especially mental health conditions. Environmental factors may play a role in the development or worsening of AD; however, there is currently no strong evidence to guide specific population- or clinic-based interventions for their avoidance. While food allergies are common in AD patients, the role of food allergens as an exacerbating factor for AD is controversial. Before starting any dietary modifications, careful evaluation should be performed by an allergist. If the patient is not well-controlled despite adequate topical therapies or is experiencing severe/worsening disease, early referral to dermatology is warranted to rule out confounding diagnoses and/or escalation to systemic therapies. Finally, it is important to recognise the racial disparities present in AD and address these when formulating treatment plans.

Key messages:

• Confounding dermatoses, either instead of or in addition to AD, should be considered in treatment-refractory AD, and the appropriate workup may be initiated while awaiting dermatology referral.
• AD patients have multiple cutaneous and extra-cutaneous comorbidities that warrant screening by internists, especially mental health conditions.

     

Characteristics,mechanism, and management of pain in atopic dermatitis: A literature review

BackgroundAtopic dermatitis (AD) is a chronic, pruritic, immune‐mediated inflammatory disease. Developments in basic science and clinical research have increased our understanding of AD. Although pain as a symptom of AD is underemphasized in previous studies, multiple researchers address pain as a frequent burden of AD. However, the exact role of pain in AD is not fully understood.AimsOur review aimed to summarize the current evidence focusing on characteristics, mechanism, and management of pain in AD.Materials & MethodsWe conducted a thorough literature review in the PubMed database to figure out different aspects discussing pain in AD, including pain symptoms, burden, the relationship between pain and itch, mechanism, and pain management in AD.Results and ConclusionAD patients affected by skin pain vary from 42.7%‐92.2% with remarkable intensity and heavy burden. Skin pain and itch interacted both in symptoms and mechanisms. Atopic skin with the impaired barrier, neurogenic inflammation mediators, peripheral and central sensitization of pain may possibly explain pain mechanism in AD. Future research is needed to clarify the commonality and disparity of pain and itch in AD in order to seek efficacious medications and treatment.     

Complementary and alternative medicine therapies in acne, psoriasis, and atopic eczema: results of a qualitative study of patients' experiences and perceptions

OBJECTIVES: The aim of this study was to explore the use of complementary and alternative medicine (CAM) therapies in patients with acne, psoriasis, or atopic eczema and the attitudes about CAM of these patients. DESIGN: This was a qualitative study, utilizing semistructured interviews and thematic analysis. SETTING: Patients were recruited from the practices of dermatologists and general practitioners in a noncapital Australian city. RESULTS: Twenty-six (26) interviews were conducted with patients with acne, 29 with psoriasis, and 7 with atopic eczema. Use of CAM therapies was common. Participants tended to value CAM over orthodox therapies because of their preference for natural approaches to their skin diseases and the perceived lesser potential for adverse effects of CAM therapies. Respondents with acne were more confident about the efficacy of CAM than were those with psoriasis or eczema. The resulting sense of control attenuated psychologic sequelae of acne. This was not apparent in psoriasis or eczema. CONCLUSIONS: Practitioners should be cognizant of the likely use of CAM and its implications (including the potential for attenuation of psychologic morbidity) in their patients who have skin diseases.     

MK-8237: a house dust mite vaccine for treating allergic rhinitis,asthma and atopic dermatitis

ABSTRACT

Introduction: Since its introduction in clinical practice one century ago for the treatment of respiratory allergic diseases, allergen-specific immunotherapy (AIT) has exhibited a relevant clinical efficacy that was subsequently confirmed in controlled trials. Thus, AIT has been accepted worldwide, as testified by guidelines and international documents. AIT is considered pivotal in the management of allergic rhinitis with or without conjunctivitis and with or without asthma. These conditions, in addition to hymenoptera venom allergy, currently are the accepted indications. The use of AIT in house-dust mite allergy still remains debated, especially due to the methodological problems in assessing this form of respiratory allergy. The more recent experimental data on MK-8237 sublingual tablets provided evidence that AIT, in the sublingual form, is effective in dust mite allergy.

Areas covered: At present, the evidence of the efficacy of AIT in conditions other than respiratory allergy are not conclusive, but encouraging results have been obtained in food allergy and atopic dermatitis. Herein, the authors discuss the data for these indications.

Expert opinion: Not all patients respond to AIT in the same way. Accordingly, AIT represents a promising path to precision medicine and hopefully will be able to reduce this burden of non-responding patients.     

Parenting and childhood atopic dermatitis: A cross-sectional study of relationships between parenting behaviour,skin care management,and disease severity in young children

BackgroundThe development of child behaviour and parenting difficulties is understood to undermine treatment outcomes for children with atopic dermatitis. Past research has reported on correlates of child behaviour difficulties. However, few research studies have sought to examine parenting confidence and practices in this clinical group.ObjectivesTo examine relationships between child, parent, and family variables, parent-reported and directly-observed child and parent behaviour, parents’ self-efficacy with managing difficult child behaviour, self-reported parenting strategies, and disease severity.DesignCross-sectional study design.ParticipantsParent-child dyads (N = 64) were recruited from the dermatology clinic of a paediatric tertiary referral hospital in Brisbane, Australia. Children had a diagnosis of atopic dermatitis of ≥3 months and no other chronic health conditions except asthma, allergic rhinitis, or allergy.MethodsParents completed self-report measures assessing child behaviour; parent depression, anxiety, and stress; parenting conflict and relationship satisfaction; self-efficacy with managing difficult child behaviour, and use of ineffective parenting strategies; and self-efficacy for managing atopic dermatitis, and performance of atopic dermatitis management tasks. The Scoring Atopic Dermatitis index was used to assess disease severity. Routine at-home treatment sessions were coded for parent and child behaviour.ResultsPearson’s and Spearman’s correlations identified relationships (p < 0.05) between self-efficacy with managing difficult child behaviour and child behaviour problems, parent depression and stress, parenting conflict and relationship satisfaction, and household income. There were also relationships between each of these variables and use of ineffective parenting strategies. Greater use of ineffective parenting strategies was associated with more severe atopic dermatitis. Using multiple linear regressions, child behaviour and household income explained unique variance in self-efficacy for managing difficult child behaviour; household income alone explained unique variance in use of ineffective parenting strategies. Self-efficacy for managing difficult child behaviour and self-efficacy for managing atopic dermatitis were positively correlated (rho = 0.48, p < 0.001), and more successful self-reported performance of atopic dermatitis management tasks correlated with less permissive (r = 0.35, p = 0.005) and less authoritarian (r = 0.41, p = 0.001) parenting. Directly observed aversive child behaviour was associated with more severe atopic dermatitis, parent stress, and parent-reported child behaviour problems.ConclusionThis study revealed relationships between parents’ self-efficacy and parenting practices across the domains of child behaviour management and atopic dermatitis management. Parents of children with more severe atopic dermatitis may have difficulty responding to child behaviour difficulties appropriately, potentially impacting on illness management. Incorporating parent and parenting support within treatment plans may improve not only child and family wellbeing, but also treatment outcomes.     

Prescript-assist probiotic-prebiotic treatment for irritable bowel syndrome: an open-label, partially controlled, 1-year extension of a previously published controlled clinical trial

OBJECTIVE: The aim of this study was to extend a previous 2-week assessment of a probiotic-prebiotic complex in patients with irritable bowel syndrome (IBS). METHODS: In this open-label, partially controlled, 1-year (14 [2] months) extension study, data were collected from patients with IBS who continued treatment following a 2-week study of the efficacy of the probiotic-prebiotic complex. Data were collected at 2 and approximately 60 weeks after the end of the original study. RESULTS: A total of 25 patients entered the 2-week extension and 22 completed the approximately 60-week follow-up study (20 women, 2 men; age range, 20-70 years; all white). Results in the control group 2 weeks after crossover to treatment were similar to those from the original study, with reductions in IBS subsyndromes, as follows: general ill feelings/nausea (P < 0.001), indigestion/flatulence (P < 0.001), and marginally colitis (P < 0.03 [1-tailed]). Treatment was associated with a continued reduction in general ill feelings/nausea at 4 weeks (P < 0.007). At >or=52-week follow-up, the rate of remissions was 81.5% to 100% (P < 0.003). CONCLUSION: Based on the results from the present 1-year extension study, treatment with this probiotic-prebiotic complex may be an option for short-term (2-4 weeks) and long-term ( approximately 60-week) reductions in IBS symptoms.     

Comparison of morphine/droperidol and tramadol/droperidol mixture for patient controlled analgesia (PCA) after cardiac surgery: a prospective, randomised, double-blind study

Aim: To determine whether a tramadol/droperidol PCA is as efficacious but causes less respiratory depression and sedation than a morphine/droperidol PCA in post cardiac surgical patients.Methods: A single centre, randomised double-blind study of 40 patients was performed. Group one or control (20) patients received a morphine/droperidol PCA and group two or experimental patients received a tramadol/droperidol PCA after cardiac surgery. PCA was commenced after extubation in the ICU, as is normal practice at this institution. Study continued for 24 h and the following data was collected; PCA consumption, pain, nausea and sedation scores as well as patient satisfaction/recovery (QoRS) score.Results: No difference between groups was detected for demographic variables. There was no statistically significant difference between groups for dose or duration of PCA use or in recorded pain scores. The morphine group had a significantly higher QoRS score. Both groups had a very low incidence of nausea.Conclusion: Tramadol/droperidol PCA does not confer a better recovery after cardiac surgery when compared to morphine/droperidol PCA.     

Transvaginal ultrasonographic assessment of Hyskon or lactated Ringer's solution instillation after laparoscopy: randomized,controlled study

We sought to evaluate two common fluids placed in the pelvis after pelvic surgery for their ability to remain in the pelvis for a time thought adequate for prevention of adhesions. Thirteen patients undergoing operative laparoscopy were randomized to receive 250 ml 32% dextran 70 (Hyskon), 250 ml lactated Ringer's solution, or no fluid (control) at the end of surgery. Serial transvaginal ultrasonograms were obtained at 1 hr, 3 hr, 6 hr, 24 hr, 96 hr (4 days), and 168 hr (7 days) after surgery. Patients were asked about side effects of fluid instillation. The volume of lactated Ringer's solution declined rapidly after instillation, with no significant difference from control at 24 hr (12 ml versus 7 ml). The volume of Hyskon did not decline rapidly by 24 hr and remained higher than the volume in controls or those receiving lactated Ringer's solution (188 ml, P = 0.003). Although the volume of Hyskon remained higher than that of lactated Ringer's solution or fluid volume in control patients by days 4 and 7, this difference did not reach statistical significance (45 ml versus 7 ml and 14 ml respectively, P = 0.39, on day 4). Patients in all groups noted abdominal pain. One patient who received Hyskon developed severe vulvar edema and another developed dyspnea. We conclude that the volume of Hyskon in the peritoneal cavity after laparoscopy does not decline as rapidly as does that of lactated Ringer's solution; however, significant side effects may limit its usefulness. Transvaginal ultrasonography is useful in monitoring fluids placed in the pelvis for prevention of adhesions.
