The Development, Validity, and Responsiveness of a Patient-Centred Outcome Measurement Tool for Evaluating Integrative Medicine Interventions

Background

The paper sets out the development, validity, and responsiveness of the Integrative Medicine Treatment Evaluation Form (IMTEF), which has been designed to measure the effects of complementary and integrative therapy (CIT) interventions in cancer and palliative care (PC) patients in a National Health Service (NHS) hospital setting. Treatment evaluation is essential for ensuring safety and quality of services, for meeting NHS governance requirements. It also helps to add to the evidence base for complementary and integrative therapies through collecting data about treatments.

Methods

A number of different Patient Reported Outcome Measures (PROMs) tools were reviewed in order to design the IMTEF, which details questions that captures both quantitative and qualitative data. The IMTEF was reviewed by patients and a range of health care practitioners.

Results

IMTEF's validity is supported by feedback from health care practitioners and patients, by its ability to detect different degrees of change in relation to change scores, and by its correlations with Visual Analog Scale (VAS) scores.

Conclusion

The IMTEF can be used to assess the effects of therapeutic bodywork and CITs when many of the patients do not have the capacity or the time to answer many questions, and when therapists do not know in advance the number of treatments that patients will be able to receive. Because of the way it is structured, it can also assess the effects after a number of sessions.

[[Translated article]]Histopathologic and Trichoscopic Correlations in Nonscarring Alopecias

Trichoscopy is an essential tool in the evaluation of alopecia. The current compilation of trichoscopic signs in this setting helps distinguish between different forms of hair loss and has improved our understanding of the pathogenic mechanisms involved. The trichoscopic signs are always linked to the pathogenic mechanisms of the alopecia being examined. We examine correlations between the main trichoscopic and histopathologic findings in nonscarring alopecias.

Scarring alopecia in chronic cutaneous lupus erythematosus with neutrophils: A new scenario with therapeutic connotations

The relationship between autoinflammatory and autoimmune conditions has been demonstrated in recent decades. Several autoimmune conditions exhibit an autoinflammatory component, which can manifest in various ways. Neutrophilic dermatosis in the context of lupus erythematosus (LE) is one example. Otherwise, neutrophils are rare in LE, except for the bullous variant and nonbullous neutrophilic LE. In this paper, we describe a case of scarring alopecia due to LE that stopped responding to a treatment that had been effective for years. The biopsy specimen demonstrated the presence of neutrophils in the inflammatory infiltrate. A treatment with dapsone was prescribed and yielded rapid improvement. This first case of scarring alopecia in the context of nonbullous neutrophilic LE emphasizes the importance of the infiltrate in determining the optimal therapeutic choice.

Shiatsu and Acupressure: Two Different and Distinct Techniques

BACKGROUND

Although shiatsu has been taught in specialized schools in Japan since 1940, there is a limited amount of research for its practice. As a result, authors substitute shiatsu with acupressure to use available research on acupressure. It is the position of the authors that, while the two share common aspects, they are substantively different. This project was undertaken to describe technical differences and advocate for a clear distinction, especially in research studies and academic discussions.

METHODS

To understand whether it is appropriate to include acupressure studies in the evidence for shiatsu an analysis of the references included in a frequently cited systematic review was conducted to collect information about the protocols. In addition, a preliminary exploration of shiatsu practitioners' perceptions about the differences between shiatsu and acupressure is described. This exploration used videos of shiatsu and acupressure techniques and asked practitioners to comment on their perception of similarity.

DISCUSSION

The results identified several key technical differences between the two, including type of pressure applied, the positioning of the thumb, and the way in which body weight is used. Researchers should separate shiatsu and acupressure in their designs and purposively choose one or the other. To facilitate such clarification, we have proposed a definition for shiatsu that may facilitate the differentiation between these two techniques.

CONCLUSION

The authors hope to stimulate discussion about the differences between shiatsu and acupressure, and to question the appropriateness of using acupressure studies as evidence of the efficacy of shiatsu. A true understanding of the efficacy of shiatsu cannot be determined until studies use a common definition of shiatsu and discontinue substituting acupressure research for evidence of shiatsu efficacy. When this happens, it is proposed that a clearer picture of the safety, efficacy, and mechanism of action of both shiatsu and acupressure will emerge.

Reconstruction Techniques of Choice for the Facial Cosmetic Units

BACKGROUND AND OBJECTIVES

A broad range of skin flaps can be used to repair facial surgical defects after the excision of a tumor. The aim of our study was to develop a practical guideline covering the most useful skin grafts for each of the distinct facial cosmetic units.

MATERIAL AND METHODS

This was a multicenter study in which 10 dermatologists with extensive experience in reconstructive surgery chose their preferred technique for each cosmetic unit. The choice of flaps was based on personal experience, taking into account factors such as suitability of the reconstruction technique for the specific defect, the final cosmetic result, surgical difficulty, and risk of complications. Each dermatologist proposed 2 flaps in order of preference for each cosmetic subunit. A score of 10 was given to the first flap and a score of 5 to the second.

RESULTS

The total score obtained for each of the options proposed by the participating dermatologists was used to draw up a list of the 3 best grafts for each site. There was notable unanimity of criteria among most of the dermatologists for reconstructive techniques such as the glabellar flap for defects of the medial canthus of the eye, the bilateral advancement flag flap or H flap for the forehead, the rotary door flap for the auricle of the ear, the Mustarde flap for the infraorbital cheek, the O-Z rotation flap for the scalp, the Tenzel flap for the lower eyelid, and the island flap for the upper lip.

CONCLUSIONS

The results of this study will be useful as a practical guide to choosing the best reconstruction technique for each of the facial cosmetic units.

Preservation of within-compound associations after blocked preexposure to two compound flavors

Three experiments investigated the extinction of the within-compound A↔X association established when two compound flavors, AX and BX, are preexposed in blocks (i.e., AX, AX, AX, ... BX, BX, BX). In Experiment 1, a group of rats received preexposure to a block of AX trials followed by a second block of BX trials (AX-BX), while a second group received blocked preexposure to the same stimuli in the opposite order (BX-AX). Subsequently, flavor A was paired with lithium chloride. This conditioning resulted in a similar reduction of consumption of flavor X in both groups. In Experiment 2 four groups of rats received blocked preexposure to AX-BX, AX-B, A-BX, or A-X. After aversive conditioning of X, consumption of A and B was significantly lower for the groups which received these flavors paired with X than for the groups for which these flavors were presented isolated. In Experiment 3 a group of rats was preexposed to a block of SaltX presentations followed by a block of BX presentations (SaltX-BX), and a second group received blocked preexposure to (BX-SaltX). After subsequent sodium depletion, consumption of X was high and similar for the SaltX-BX and for the BX-SaltX groups. These results indicate that the within-compound association established in the first block of a blocked preexposure is not extinguished when the preexposure phase is concluded.

Clinical diagnosis of toenail onychomycosis is possible in some patients: cross-sectional diagnostic study and development of a diagnostic rule

BACKGROUND

Suspected toenail onychomycosis is a frequent problem. Clinical diagnosis has been considered inadequate.

OBJECTIVES

To assess the diagnostic accuracy of clinical findings for detecting fungi in toenails, and to develop and validate a clinical diagnostic rule aimed at improving dermatologists' diagnosis of onychomycosis.

METHODS

A cross-sectional diagnostic study was performed including a total of 277 patients seen by 12 dermatologists. The gold standard was the presence of dermatophytes on culture or a positive nail plate biopsy. For each sign we described prevalence, sensitivity, specificity, positive and negative predictive values, and likelihood ratios for positive and negative results. We developed a diagnostic clinical rule and validated it in a subsample.

RESULTS

Helpful findings to predict the presence of fungi are: previous diagnosis of fungal disease; abnormal plantar desquamation (affecting > 25% of the sole); onychomycosis considered the most probable diagnosis by a dermatologist; and presence of interdigital tinea. When dermatologists considered onychomycosis the most probable diagnosis and plantar desquamation was present (13% of patients), the positive predictive value for presence of fungi was 81%. When both signs were absent (34% of patients), the positive predictive value for absence of fungi was 71%. In other situations, clinical diagnosis might not give enough information to decide on therapy.

CONCLUSIONS

In 13% of the patients (a large number in absolute terms), when dermatologists consider onychomycosis the most probable diagnosis and plantar desquamation is present, therapy should be started without any further test, as clinical diagnosis is at least as accurate as laboratory tests. In other situations, an optimal management strategy should be defined.
