Diagnostic delay, comorbid hidradenitis suppurativa and the prognostic value of bacterial culture in folliculitis decalvans: A cohort study.

BACKGROUND: Folliculitis decalvans (FD) is a type of primary neutrophilic cicatricial alopecia often leading to irreversible hair loss. Data on its epidemiology, clinical features, outcomes, and prognostic factors are limited. OBJECTIVE: To evaluate a cohort of patients with FD and identify characteristics of severe disease and prognostic factors which impede remission. PATIENTS AND METHODS: This retrospective cohort study included 192 patients diagnosed with FD and followed for at least six months at a tertiary center between 2010 and 2020. RESULTS: There was a diagnostic delay averaging 22.2 (± 29.7) months. Comorbid follicular occlusion disorders were common. Bacterial cultures were positive in 45.6% of the cases, with Staphylococcus (S.) aureus being the most common pathogen. Severe disease was associated with comorbid hidradenitis suppurativa and a positive bacterial culture, particularly S. aureus. 50.7% of patients experienced complete remission: 32% within the first six months of treatment and 18.7% later during follow-up. Relapses were frequent. Negative prognostic factors for achieving remission included younger age and a positive bacterial culture. CONCLUSIONS: There is a need for the education of dermatologists to reduce the diagnostic delay. Screening FD patients for comorbid hidradenitis suppurativa and obtaining bacterial cultures is important for treatment planning.

Changing spectrum of hair and scalp disorders over the last decade in a tertiary medical centre.

BACKGROUND: Hair- and scalp-related disorders (HSRDs) encompass a wide range of conditions that affect people of all ages. OBJECTIVE: To evaluate the workload and trends in HSRDs at an outpatient dermatological clinic in a tertiary medical centre over a 10-year period. METHODS: Medical records for HSRD visits to the outpatient dermatology clinic at the Sheba Medical Center, an Israeli tertiary care center, were reviewed between 1 January, 2010 and 31 December, 2020. RESULTS: There were 10,396 HSRD visits with a new-to-follow-up visit ratio of 1:1.9. The annual number of HSRD visits, as well as their proportion out of all dermatological outpatient visits, have increased from 295 (1.24%) in 2010 to 1726 (9.44%) in 2020. The patients' mean age was 35.3 years (women 39.5 years, men 28.8 years), age range 1-87 years. Over the decade, there was a growing predominance of women with an average female-to-male ratio of 2:1. The winter season accounted for 28.7% of annual visits, followed by the autumn (25.6%), summer (24.3%) and spring (21.4%). The most prevalent HSRDs included androgenetic alopecia (30.6%), alopecia areata (19.3%), telogen effluvium (15.4%), non-scarring folliculitis (15.4%), seborrheic dermatitis (14.9%), lichen planopilaris (7.1%) and folliculitis decalvans (6.6%). Androgenetic alopecia demonstrated the highest increase over the decade examined (from 17% to 32%). CONCLUSION: HSRDs account for a significant percentage of visits at a tertiary dermatology outpatient clinic. The number of HSRD visits has increased annually over the past decade. The recent advancement in diagnosis and treatment may account, at least in part, for the growing burden of HSRDs within dermatological ambulatory care.

New-Onset Guttate Psoriasis: A Long-Term Follow-Up Study.

BACKGROUND: Guttate psoriasis (GP), a distinct variant of psoriasis, is more common in children and adolescents. The long-term course of these patients has sparsely been examined, with few studies reporting the rates of relapse, persistence, and further development of the psoriasis vulgaris phenotype. OBJECTIVES: The objective of this study was to characterize the long-term outcomes of new-onset GP and elucidate the potential factors associated with a persistent disease course. METHODS: This was a retrospective cohort study. Patients diagnosed with new-onset GP between 2009 and 2020 with a follow-up period of at least 1 year, were enrolled. The examinees were evaluated by dermatologists. Detailed data retrieved from the examinees' medical files included demographics, disease characteristics, treatment, and comorbidities. A structured telephone questionnaire was used to determine the current psoriasis status: type, severity, and extent. At the end of follow-up, patients with a persistent disease course, defined as having lesions at least a year after disease onset, were compared with patients in complete remission without further psoriasis symptoms. RESULTS: A total of 120 patients (mean age 28.8 years [±15.2], 58.3% women) with new-onset GP flare were identified. At the end of follow-up period (mean 6.2 years [±3.1]), 49.1% (n = 59) of the patients reported active persistent psoriasis. A switch to the psoriasis vulgaris phenotype occurred in 17.5% (n = 21) of the study cohort. Persistent psoriasis was associated with male sex (OR = 2.1, p < 0.05), multiple disease flares (>3; OR = 9.1, p < 0.001), switch to the vulgaris phenotype (OR = 4.16, p < 0.001), and palmoplantar involvement (OR = 5.2, p < 0.01). CONCLUSION: A persistent disease course is common among patients with new-onset GP, with most retaining their guttate phenotype throughout the disease course. Persistency was associated with male sex, multiple GP flares, switching to the vulgaris phenotype, and palmoplantar involvement.

Illness Perception Regarding Early-stage Mycosis Fungoides among Dermatologists: A Multi-centre Cross-sectional Study.

Early-stage mycosis fungoides is a rare cutaneous T-cell lymphoma with a good prognosis. Data regarding patients' illness perception of mycosis fungoides are accumulating. However, investigating the dermatologists' viewpoint is also essential, as it shapes the therapeutic relationship and doctor-patient communication. The aim of this study was to investigate the aspects of dermatologists' illness perception towards early-stage mycosis fungoides and the way they present it to patients. Twenty-five dermatology residents and 55 attending physicians from all Israeli dermatology departments and the community completed the study questionnaires online. Dermatologists viewed mycosis fungoides as a chronic disease, causing a moderate emotional burden. In contrast to previously published data regarding patients' illness perception, dermatologists demonstrated dominancy in the notion that patients were able to control their disease. Most dermatologists thought that patients perceived mycosis fungoides as an indolent lymphoma that causes anxiety. Dermatologists used a high diversity of themes when presenting mycosis fungoides to patients. The differences between the residents' and attending physicians' perceptions were minimal. Dermatologists have a kaleidoscope of views regarding the way they perceive mycosis fungoides, the way they think patients perceive it, and the way they communicate with patients. Maintaining patient-centred communication enables dermatologists to identify these gaps and view mycosis fungoides from their patients' perspective.

Illness Perception, Perceived Social Support and Quality of Life in Patients with Pemphigus Vulgaris: What Should Dermatologists Know?

Data regarding the impact of psychological factors in patients with pemphigus is sparse. This study evaluated the correlation of demographic, clinical, and psychological parameters with quality of life in 58 patients with pemphigus. Illness perception showed a realistic view, with the highest scores for cyclical course (3.35 ± 0.09) and treatment control (3.08 ± 0.06). Mean scores for perceived social support were relatively high from family and significant others (5.89 ± 0.18 and 5.66 ± 0.23, accordingly), and relatively low from friends (4.55 ± 0.24). There were no correlations be-tween demographic, clinical parameters, perceived social support, and Dermatology Life Quality Index. Beliefs in cyclical course, emotional influence, psychological cause, and treatment control correlated significantly with quality of life. Stronger beliefs in self-control, chronicity, and accidental cause predicted higher quality of life, while stronger beliefs in cyclical course, psychological cause, and risk factors predicted lower quality of life. In order to enhance QoL, dermatologists should deliver the message to the patients that pemphigus is a chronic disease rather than cyclical and unexpected, and stress the patients' role in controlling it.

Illness perception, coping, and quality of life in early-stage Mycosis fungoides

Abstract Background: Mycosis fungoides is the most common type of cutaneous T-cell lymphoma. Most early-stage mycosis fungoides cases follow an indolent course, hence considered by doctors a relatively easy condition. However, since mycosis fungoides bears the title of cancer, patients might perceive it differently. Objective: To investigate patients' illness perception, and its relationships to quality of life, depression, anxiety, and coping among early-stage mycosis fungoides patients. Methods: A cross-sectional questionnaire-based study was conducted. Patients from a single tertiary medical center completed the Revised Illness Perception Questionnaire, the MF/SS-CTCL Quality of Life scale, the Hospital Anxiety and Depression Scale, and The Mental Adjustment to Cancer Scale. Results: Thirty patients (25 males, five females, mean age 51.60) with stage I mycosis fungoides were enrolled. Mycosis fungoides had a little impact on patients' daily life, quality of life, and levels of depression and anxiety, and they generally coped well. Disease understanding was low and was negatively correlated with impairment to quality of life and depression. Patients felt that stress and worry were features of the disease's etiology. Study limitations: A small sample of patients was included. Conclusion: Patients with early-stage mycosis fungoides adapt well to their disease. Psychological interventions should be aimed at improving patients coping style and enhancing illness understanding, in order to maintain high quality of life.

Evaluation of the polymerase chain reaction-based T-cell receptor ß clonality test in the diagnosis of early mycosis fungoides.

BACKGROUND: T-cell receptor (TCR) clonality may help establish a diagnosis of mycosis fungoides (MF). Routine clonality analysis is performed by using a polymerase chain reaction TCR- gamma assay, yet with this method, 10% to 50% of T-cell lymphomas escape detection. TCR- beta gene rearrangement is an additional assay. Data about its efficacy are controversial. OBJECTIVE: To evaluate the role of TCR-ß assay in the diagnosis of early MF. METHODS: A retrospective study of 61 skin biopsies, 20 from patients with MF, 30 from patients suspected to have early MF, and 11 from patients with chronic inflammatory skin disease. RESULTS: Monoclonality was detected in 16 of 20 (80%) MF cases: 15 (75%) with TCR-ß and 12 (60%) with TCR-γ assay. Of the 30 suspected cases of early MF, 14 showed monoclonality with TCR-ß, and only 5 of 14 showed monoclonality with TCR-γ assay. None of the chronic inflammatory condition samples showed monoclonality. Therefore, TCR-ß clonality assay was more sensitive than TCR-γ in early MF (83% vs 43%; P = .002). LIMITATIONS: This was a retrospective, relatively small study. CONCLUSION: TCR-ß showed a higher sensitivity rate compared with TCR-γ in early-stage MF. The combined use of the TCR-ß and TCR-γ clonality tests can significantly improve the diagnosis rate of early-stage MF.

Assessing an Intervention Focused on Enhancing Interpersonal Communication Skills and Humor: A Multi-Method Quasi-Experiential Study Among Medical Students.

Teaching and applying interpersonal communication skills (ICS) and humor in medicine is challenging. The present study assessed an innovative course focused on enhancing ICS and humor based on the Four Habits Model and theater concepts. Medical students enrolled in the course (the study group) were assessed pre- and post-intervention, as well as compared with their peers (the control group) using quantitative methods to measure attitudes, self-efficacy, and behaviors. Qualitative methods were used to learn about students' change in perceptions related to ICS and humor following the course, as well as their experiences of developing these skills during the course. Post-intervention study group participants scored significantly higher on all ICS measurements and on humor behavior compared with pre-intervention, and significantly higher on all humor measurements compared with control group participants. Interviews indicated students' increased understanding and difficulties in learning these skills. Analyses showed how framing humor as one possible ICS and focusing on specific parts of the medical encounter can promote patient-centered care.
