RESUMEN
BACKGROUND: Hidradenitis suppurativa (HS) is a systemic disorder associated with various metabolic and inflammatory comorbidities. Although HS shares risk factors and pathogenic pathways with various respiratory conditions, few studies have explored the relationship between HS and respiratory disease. METHODS: This is a cross-sectional, case-control, population-based study that examined the United States National Inpatient Sample database from January 1, 2002, to December 31, 2012. HS was identified using ICD-9-CM codes during hospital admissions. Multivariable logistic regression was used to evaluate for adjusted associations between HS and respiratory diagnoses as compared to matched controls. RESULTS: Twenty-three thousand seven hundred and sixty-seven hospital admissions for HS were compared with 95,068 age- and sex-matched controls. HS patients had significantly higher adjusted odds of asthma (OR: 1.233; 95% CI: [1.170-1.299]; P < 0.001), chronic airway obstruction (OR: 1.532; 95% CI: [1.419-1.651]; P < 0.001), sarcoidosis (OR: 1.601; 95% CI: [1.157-2.214]; P < 0.001), and sleep apnea (OR: 1.274; 95% CI: [1.182-1.374]; P < 0.001). CONCLUSION: HS is associated with several common forms of respiratory disease. Knowledge of these associations may allow for better recognition of respiratory disease in HS patients.
RESUMEN
BACKGROUND: Hidradenitis suppurativa (HS) is associated with several comorbidities such as diabetes mellitus and cardiovascular diseases. These comorbidities are also risk factors for chronic kidney disease (CKD), yet little is known about the risk of CKD in HS patients. OBJECTIVES: The objective was to study the prevalence of CKD in HS patients. METHODS: Cross-sectional population-based study using the United States National Inpatient Sample database between January 1, 2002 and December 31, 2012 was performed. RESULTS: We identified 23,767 hospital admissions for HS patients and 95,068 admissions for age- and gender-matched controls. The prevalence of CKD in HS patients was 6.3% (1,497/23,767) compared to non-HS controls which was 4.3% (4,052/95,068). The association of CKD was strongest in HS patients, who were ≥60 years old, 16.9% (475/2,811), male 7.3% (695/9,556), obese 7.8% (407/5,209), diabetic 12.5% (890/7,105), hyperlipidemic 13.3% (416/3,126), and had cardiovascular diseases 12.5% (631/5,045). The crude odds ratio of CKD in HS patients was 1.5 (95% CI: 1.420-1.605) compared to non-HS patients. The association remained significant after adjusting for important covariates with adjusted odds ratio of CKD in HS patients of 1.1 (95% CI: 1.014-1.176) compared to non-HS patients. CONCLUSIONS: Our findings show that there is a possible association of HS with CKD. Any signs of CKD should be assessed by a nephrologist as early diagnosis can hopefully prevent further progression.

Harlequin ichthyosis (HI) is a rare, life-threatening genodermatosis that is characterized by thick, scaly, hyperkeratotic plaques throughout the skin and is typically associated with severe ectropion, eclabium, flexion contractures, and dysplastic ears. HI is thought to be caused by a loss-of-function mutation in the ABCA12 gene. It has traditionally been thought to be difficult to treat, as there are currently no treatments available that are approved by the Food and Drug Administration (FDA). We present a case of a 15-year-old boy with HI and a complex medical history who was treated with a trial of off-label ustekinumab. There was an initial mild improvement in his erythema within one month of treatment, but by his one-year follow-up, ustekinumab had failed to produce a significant treatment response and was, thus, discontinued from his regimen. This case report highlights that although ustekinumab may be a viable treatment option for other ichthyotic entities, more research is needed to evaluate its clinical safety and efficacy in treating pediatric patients with HI.
RESUMEN
The Symposium on Hidradenitis Suppurativa Advances (SHSA) is a joint meeting of the United States Hidradenitis Suppurativa Foundation (HSF) and the Canadian Hidradenitis Suppurativa Foundation (CHSF). This annual cross-disciplinary meeting brings together experts from around the world in an opportunity to discuss the most recent advances in the study of hidradenitis suppurativa (HS). The fifth annual meeting was held virtually on 9-11 October 2020. A record 347 attendees, including 79 people with HS, from 20 different countries attended. Key take-home points included: Clinicians can optimize each visit by listening, provide education, and discuss treatments; a patient decision aid for HS (HS-PDA) is a freely available tool (www.informed-decisions.org); COVID-19 severity in HS patients was not different for patients treated with/without a biologic; comorbidity screening recommendations will be published soon; neutrophil extracellular traps (NETs) may play a role in HS; memory B cells, T helper 1 cytokines, and interleukin 1 signaling contributes to HS pathogenesis and are targets for new therapies; novel therapies are showing promise including a new JAK1 inhibitor (INCB054707) and brodalumab; and HS-specific outcome measures have emerged to better monitor disease severity, flare, and progression including a patient reported measure (HiSQOL) and an HS-specific investigator global assessment.

BACKGROUND: Limited data is available on the burden of dermatologic disease including disease distribution and providers of care. Research is needed to facilitate health care planning and improve patient care. OBJECTIVES: To investigate the demographics and economics of the provision of dermatologic care in a universal health care system from fiscal year 2000 to 2016. METHODS: A retrospective population-based analysis was performed on physician billing claims for dermatologic conditions from April 1, 2000 to March 31, 2017. Data came from the province of Ontario's universal health care plan claims records accessed through IntelliHealth. RESULTS: Dermatologic claims made up 3.6% of all physician claims, with a 20% increase seen over time. The cost of dermatologic claims increased by 70% between fiscal 2000 and 2016, with the average cost per claim increasing by 41%. However, the cost of dermatologic claims as a percentage of all health care claims experienced a decline from 3.5% in fiscal 2000 to 2.8% in fiscal 2016. Over the study period, family physicians submitted 56% to 62% of dermatologic claims, dermatologists 24% to 29%, pediatricians 3% to 4%, and internists 1%. Overall, internists billed the highest average cost per dermatologic claim ranging from $39 in 2000 to $60 in 2016, followed by pediatricians at $33 to $58, dermatologists at $28 to $39, and family physicians at $23 to $30. CONCLUSIONS: The demographic and economic burden of dermatologic disease is changing over time, with implications for health care planning, advancing medical education, and patient care.

BACKGROUND: Several studies report a high prevalence of inflammatory arthritis among hidradenitis suppurativa (HS) patients. OBJECTIVES: To study the association between HS and inflammatory arthritis. METHODS: The systematic review and meta-analysis were performed according to the PRISMA guidelines to identify the association between HS and inflammatory arthritis, spondyloarthritis, ankylosing spondylitis (AS), and rheumatoid arthritis (RA). RESULTS: Seven studies were entered in the analysis, with 200,361 HS patients and 385,599 controls. Pooled analysis illustrated a significantly increased risk of inflammatory arthritis in HS patients compared to controls (odds ratio [OR] 3.44; 95% confidence interval [CI] 1.92-6.17). There was also a statistically significant association between HS and spondyloarthritis (OR 2.10; 95% CI 1.40-3.15), and between HS and AS (OR 1.89; 95% CI 1.14-3.12). Moreover, pooled analysis showed a statistically significant association between HS and RA (OR 1.96; 95% CI 1.28-2.98). CONCLUSIONS: Our findings show that HS patients have a 3-fold increased risk of developing inflammatory arthritis. HS patients are specifically at a higher risk for spondyloarthritis, its subtype AS, and RA.

Complete visualization of lesions is critical for the accurate diagnosis and management of dermatological diseases. Currently, the most readily available technologies used by dermatologists include dermoscopy and photography. Nevertheless, ultrasound has emerged as a useful non-invasive modality in dermatology, which can be added to the clinical examination supporting an early and more accurate diagnosis. Moreover, there are significant technological advances in recent years, such as the development of handheld devices and ultra-high frequency probes that have expanded the integration of ultrasound into daily dermatology practice. In this article, we reviewed the most common applications of ultrasound in the field of dermatology.

BACKGROUND: Mycosis fungoides (MF) and Sézary syndrome (SS) are the most common subtypes of cutaneous T-cell lymphoma (CTCL). There is currently no cure for CTCL, and treatment is aimed at limiting disease progression. This study evaluated the efficacy and tolerability of alitretinoin in CTCL management. METHODS: A retrospective, multicenter study was conducted on CTCL patients treated with alitretinoin as a primary agent or in combination with standard therapies. RESULTS: Forty-eight patients with MF (n = 40) and SS (n = 8) with a median age of 59.7 years (±14.3) were eligible for study inclusion. Treatment response data were evaluated in 40 patients and safety in 42 patients. 40.0% of the patients had early-stage, 43.8% had advanced-stage CTCL, and in 16.7% of patients there was insufficient information for staging. 40.0% (16/40) of the patients achieved a complete or partial response, whereas 47.5% (19/40) achieved stable disease, 12.5% (5/40) had progressive disease, and there were no cases of disease relapses in responders. Both early and advanced stages of CTCL were responsive to alitretinoin as a primary or combined modality. Alitretinoin was well tolerated, and 64.3% (27/42) of patients did not report any side effects. The most commonly observed side effect was hypertriglyceridemia. CONCLUSIONS: This retrospective analysis supports the efficacy and safety of alitretinoin in clearing skin disease and preventing disease progression in CTCL as a monotherapy or in combination with standard therapies.

BACKGROUND: Hidradenitis suppurativa (HS), characterized by inflammatory nodules, sinus tracts, and abscesses, has been linked to several factors, including immune dysfunction and obesity, which are thought to contribute to its development. Several follicular disorders have also been associated with Down syndrome (DS), a common chromosomal disorder, including HS, although studies on this topic are limited. OBJECTIVES: To characterize HS in Down syndrome patients and to further examine the association between HS and DS compared to HS patients without DS. METHODS: We systematically searched MEDLINE, Embase, Web of Science, and CENTRAL electronic databases from their dates of conception to February 2020. Random-effects meta-analyses were performed analyzing (a) HS characteristics between DS and non-DS participants, and (b) prevalence or association between HS and DS compared to non-DS individuals. RESULTS: Twelve studies were included in this systematic review, with a total of 358 participants presenting with both HS and DS. Pooled analysis of mean differences between DS and non-DS participants presenting with HS found a significantly younger age of HS symptom onset for DS patients (-6.24; 95% CI, -10.01--2.24). A meta-analysis examining the association between HS and DS found a significantly increased likelihood of HS in DS patients (OR 9.61; 95% CI, 5.70-16.20). CONCLUSIONS: Our findings suggest an association between HS and DS, with DS patients suffering from an earlier onset of HS symptoms compared to non-DS patients.
