Color Doppler Ultrasound Assessment of Subclinical Activity With Scoring of Morphea.

BACKGROUND: Detection of activity in morphea is paramount for adequately managing the disease. Subclinical ultrasound involvement on inactive lesions or healthy skin areas adjacent to morphea has not been described to date. OBJECTIVES: The study aimed to detect morphea's subclinical activity by Color Doppler ultrasound not identified with the clinical scorings. MATERIALS & METHODS: This cross-sectional retrospective study was done from January 2014 to July 2019 in patients with a clinicopathological diagnosis of morphea. The modified Localized Scleroderma Skin Severity Index (mLoSSI) and The Ultrasound Morphea Activity Score (US-MAS) were used to correlate clinical and subclinical activity. RESULTS: A total of 36 patients met the inclusion criteria. 54% of cases presented subclinical activity in areas adjacent to the clinically active lesion, 23% in nonadjacent regions, and 23% demonstrated activity at a clinically inactive lesion site.100% of patients with morphea "en coup de sabre" involving the frontal region of the face concomitantly presented both subclinical activities of morphea on the frontal facial region and the scalp following the same axis.A positive relationship was observed between the degree of clinical activity measured by mLoSSI and US-MAS scoring.The main limitations of our study were the low number of patients and the inability to detect alterations < 0.1 mm. CONCLUSIONS: Subclinical activity is frequent in morphea, can extend beyond the lesional areas, including apparently noninvolved adjacent and distant corporal regions, and can be detected by color Doppler ultrasound.

Can Ultrasound Examinations Generate Pain in Hidradenitis Suppurativa Patients? Results from a Multicentric Cross-Sectional Study.

BACKGROUND: Pain is not a trivial issue for hidradenitis suppurativa (HS) patients and has been considered a domain in the Core Outcome Set. To date, there is no evidence about pain caused by the ultrasound examinations. OBJECTIVE: The aim of the study was to assess the presence of pain generated by the ultrasound examinations of HS patients. METHODS: A multicentric cross-sectional study for detecting pain during the ultrasound examinations of HS patients using a validated verbal questionnaire immediately after the imaging studies. Statistical analysis included demographic data and possible associations with sex, age, location, clinical (Hurley), and ultrasonographic scoring (SOS-HS). The statistical tests were two proportions Z test, χ2 test, Student's t test, and ANOVA. A p < 0.05 was considered significant. RESULTS: 317 patients met the criteria. 77.3% of them did not present pain. Of cases with pain, 59.8% were mild, 16.7% moderate, and 23.6% severe. No significant association was found with sex, age, staging, location, or the number of affected regions. Although nonsignificant, severe pain cases were more frequent in the clinical Hurley III and ultrasonographic SOS-HS III stages. CONCLUSION: Pain generated by the ultrasound examination of HS patients is infrequent.

Rápida implementación de teledermatología durante la pandemia por COVID-19: lecciones aprendidas de un departamento académico de Dermatología / Rapid implementation of tele-dermatology during COVID-19 pandemic in an academic dermatology department

BACKGROUND: The day after COVID-19 quarantine started, we initiated patient care through Tele-dermatology. AIM: To report the experience of the implementation of Telemedicine in dermatology and to assess its impact on the number of dermatological visits compared with the pre-pandemic period. MATERIAL AND METHODS: The study was conducted between March 27th, 2020, and April 30th, 2020. All patients submitted clinical images of their skin condition via secure email before the telemedicine visit. All telemedicine visits were conducted using the Zoom video conferencing platform. Patient demographics and medical history were recorded. If the dermatologist was unable to reach a diagnosis, the patient was sent for an in-person visit, skin biopsy, or additional laboratory workup. RESULTS: We recorded 1,357 Tele dermatology visits from 1,222 patients aged 29 ± 18 years (38% males). Visits increased from 104 to 298 from the first to the last week, corresponding to 17% of the patient volume seen before the pandemic (1,709 in-person patients/week). A preliminary diagnosis was made in 95% of cases. Ninety percent of patients sent photos. Fifty eight percent of cases were chronic diseases, and were classified as inflammatory in 68%, infectious in 15%, neoplastic/tumoral in 7%, or other conditions in 11%. Less than 1% of these visits were COVID-19 related. CONCLUSIONS: In this prospective study of Tele-dermatology lasting five weeks, a preliminary diagnosis could be made in approximately 95% of cases and in the first five weeks of implementation, a volume of consultations equivalent to 17% of those made in the pre-pandemic period was carried out. Therefore, Tele-dermatology can be implemented quickly and successfully in practices when healthcare access is limited.

Ultrasonographic Subclinical Signs of Inflammation of the Lacrimal, Parotid, and Submandibular Glands in Users of Cosmetic Fillers.

OBJECTIVES: To detect ultrasonographic inflammatory signs in the lacrimal, parotid, and submandibular glands in cosmetic fillers (CFs) users. METHODS: A prospective and cross-sectional ultrasound study of the glands in cases with CFs was performed. The sample included users of hyaluronic acid, silicone oil, polymethylmethacrylate, polycaprolactone, calcium hydroxyapatite, and polyacrylamide. Abnormalities of the parenchyma and hypervascularity signs of the glands were compared with a control group (n = 10), evaluated by 2 observers, and correlated with the type, number, and location of the facial CFs. Cohen's kappa test and logistic regression models with odds ratios (OR) adjusted by age with 95% CI were performed. RESULTS: Sixty-three patients with CFs met the criteria. Parotid and submandibular glands had the highest percentage of parenchymal involvement: 87.3 and 88.9%, respectively (p <.01). Abnormalities of the echostructure of the parenchyma and hypervascularity of the glands were detected with all kinds of fillers without significant differences per type. A significant substantial interrater kappa (0.61) with an agreement of 90% for all glands among observers was found. CONCLUSION: Users of common types of CFs frequently present subclinical ultrasonographic signs of inflammation of the lacrimal, parotid, and submandibular glands. Further research on the topic seems necessary.

Low effectiveness of methotrexate in the management of localised scleroderma (morphea) based on an ultrasound activity score.

BACKGROUND: The effectiveness of methotrexate (MTX), a first-line treatment for localised scleroderma (morphea), has not been assessed using colour Doppler ultrasonography (CDU). OBJECTIVES: We aimed to ultrasonographically monitor disease activity in patients with morphea treated with MTX, assessing its effectiveness using an Ultrasound Morphea Activity Score (US-MAS). MATERIALS & METHODS: A retrospective cohort of 22 patients was studied between July 2014 and July 2019. The morphea of each patient, treated with MTX, was confirmed by histology and all patients had at least two CDU examinations. The US-MAS is based on published ultrasound signs of disease activity validated by histology. A weight-adjusted average MTX dose (mg/kg/wk) was used to standardize dosage, weight, and time between CDU examinations. The difference in US-MAS between two CDU examinations was determined. Statistical analyses included Wilcoxon and Fisher exact tests, the Spearman correlation coefficient, and risk ratios with 95% confidence intervals. To create two groups, we determined the median of the sample as the cut-off point for MTX dose (0.265 mg/kg/week). Significance was set at p≤0.05; Results: In all cases, CDU examinations showed subclinical signs of activity beyond the visible lesional borders, either in the same or adjacent corporal segments. A negative correlation was found between the change in US-MAS and MTX dose (Spearman coefficient, -0.45; p = 0.035). The group dosed at ≥0.265 mg/kg/wk showed a non-significant change in US-MAS (2-point decrease). No case became inactive. CONCLUSION: MTX is a treatment with a low effectiveness for morphea, causing only slight decreases in ultrasound activity at higher doses.
