RESUMO
Generalized pustular psoriasis (GPP) is a rare but severe form of psoriasis. An early onset of the diseases is correlated with mutations among IL36RN, CARD14, AP1S3, MPO and SERPINA3 genes. Systemic biological agents including anti-TNF-α, anti-IL-17, anti-IL-12/IL-23, anti-IL1R, anti-IL1ß and anti-IL-36R act as novel treatment methods for GPP. Herein we report a female infant clinically diagnosed with GPP since she was 10-month-old. Results of whole-exome sequencing (WES) and Sanger sequencing revealed a reported heterozygous IL36RN (c.115+6T>C) and another reported heterozygous SERPINA3 frame-shifting variant (c.1247_1248del). Initial cyclosporin treatment for the patient led to a partial remission of the symptoms. However, the patient reached nearly total remission of pustules and erythema after anti-TNF-α inhibitor etanercept treatment. Results of further RNA sequencing (RNA-seq) done on peripheral blood mononuclear cells correlated with the clinical responses, showing that cyclosporin suppressed a portion of the neutrophil-related genes, while most genes associated with neutrophil activation, neutrophil-mediated immunity and degranulation were downregulated by the subsequent etanercept treatment. We report this case to demonstrate WES and RNA-seq in combination could come in handy in reaching a precise diagnosis and in evaluating or even predicting the molecular alterations underlying clinical treatment effectiveness.

BACKGROUND: Hidradenitis suppurativa (HS) significantly diminishes the quality of life for patients. Delayed diagnosis represents a significant challenge in effectively managing HS. OBJECTIVES: To identify and characterize the key mediator in HS. METHODS: Bioinformatic transcriptomic analysis was applied to identify potential candidates contributing to the disease process of HS. Skin samples from 40 patients with HS, four with psoriasis and 29 with normal skin were included. The expression of interleukin (IL)-17A was evaluated and compared among samples of normal skin, psoriatic skin and skin from different stages of HS by immunohistochemistry or dual-colour immunofluorescence. In vitro experiments and RNA sequencing analysis were also conducted to validate the expression of IL-17A and its pathogenic effect in HS. RESULTS: Transcriptomic database analyses identified IL-17 signalling as a potential contributor to HS. In HS, the predominant IL-17A+ cell population was identified as mast cells. IL-17A+ mast-cell density was significantly elevated in HS, especially in samples with advanced Hurley stages, compared with normal skin and psoriasis samples. The close contact between IL-17A+ mast cells and IL-17 receptor A (IL-17RA)-expressing keratinocytes was demonstrated, along with the significant effects of IL-17A on keratinocyte cell proliferation and HS pathogenic gene expression. Treatment with biologics (brodalumab or adalimumab) reduced the severity of the disease and the number of IL-17A+ mast cells in affected tissues. CONCLUSIONS: The presence of high-density IL-17A+ mast cells may serve as a valuable pathological marker for diagnosing HS. Moreover, developing therapeutic drugs targeting IL-17A+ mast cells may provide a new approach to treating HS.

Psoriasis in different body regions displays varying therapeutic responses to biologics, whereas currently relevant studies remain scarce. We retrospectively reviewed the treatment responses of patients with moderate-to-severe psoriasis, who completed the two-year reimbursed ustekinumab or secukinumab treatment in two medical centers in Southern Taiwan. Demographic profiles and body regional PASI scores (head/neck, trunk, upper and lower limbs) along the treatment course were recorded. The proportions of patients attaining PASI 75, 90, 100 and the extent of body regional PASI score improvements were compared in biologic naïve or experienced patients. A total of 57 and 67 patients receiving ustekinumab and secukinumab injections, respectively, were included. Overall, patients receiving secukinumab showed higher degrees of PASI score improvements along the two-year treatment course. The lower limbs had the highest, and the upper extremities and head/neck had the lowest post-treatment PASI scores regardless of prior biologic use in the groups of ustekinumab and secukinumab. The upper limbs showed the highest, while the lower limbs had the lowest complete remission rate (regional specific PASI 100) in response to ustekinumab (upper limbs 48.7%, lower limbs 25.6%) and secukinumab (upper limbs 77.1%, lower limbs 42.8%) in biologic naïve groups. Our study demonstrated that lower limbs were the most treatment-refractory area in response to ustekinumab and secukinumab injections, while the upper limbs and head/neck region had a better response.

BACKGROUND: The increasing use of biologics is accompanied by a risk of hepatitis B (HBV) and C virus (HCV) reactivation. OBJECTIVE: To determine the predictors of HBV and HCV reactivation in patients with psoriasis receiving biologics. METHODS: This study screened 2060 patients with psoriasis (3562 treatment episodes) who were taking biologics from 2009 to 2018. There were 359 patients with psoriasis with HBV (561 treatment episodes) and 61 with HCV infection (112 treatment episodes). RESULTS: During 8809 and 1522 person-months of follow-up, 88 treatment episodes for HBV involved HBV reactivation, and 14 episodes of HCV involved reactivation. The reactivation rate was significantly higher in treatment episodes of chronic HBV infection than in that of occult HBV (34.3% vs 3.2%, P = .001) and resolved HBV (34.3% vs 5.0%, P < .001). The multivariate analysis revealed that being hepatitis B surface antigen seropositive, being hepatitis B e-antigen seropositive, and tumor necrosis factor-α-inhibitor therapy were risk factors for HBV reactivation, whereas antiviral prophylaxis was effective in reducing the risk of HBV reactivation. No predictors were significantly associated with HCV reactivation. LIMITATIONS: Observational design and a lack of a comparison group. CONCLUSION: Patients with psoriasis on biologics have a risk of HBV and HCV reactivations, particularly those who are seropositive for hepatitis B surface antigen and hepatitis B e-antigen and undergoing tumor necrosis factor-α-inhibitor therapy.

Hidradenitis suppurativa is a cutaneous chronic inflammatory disease that is estimated to affect about 1% of the population and caused pain, malodorous discharge, disfigurement, and poor quality of life with psychosocial problems. The typical features are recurrent painful nodules, abscesses, and sinus tracts on the axillae, groins, gluteal areas, and anogenital regions since postpuberty. Smoking and obesity are two major triggering factors of hidradenitis suppurativa. Women are prone to have hidradenitis suppurativa than men in Western countries, but the male-to-female ratio is reversed in oriental countries. The disease severity can be affected by menstruation, pregnancy, and menopause. Furthermore, the phenotypes are different among men and women with hidradenitis suppurativa. Men are prone to have buttock involvement while women are prone to have axillary, groins, and submammary lesions. This review introduces the skin appendages and pathophysiology of hidradenitis suppurativa and then focuses on the sex difference and the effects of sex hormones on hidradenitis suppurativa and current hormone-associated treatments.

Autosomal recessive dystrophic epidermolysis bullosa (RDEB) is characterized by recurrent mucocutaneous blistering with non-healing ulcers which are often complicated by squamous cell carcinoma (SCC). Despite having as high as 80% death rate from SCC, RDEB still does not have an effective treatment. We report on the efficacy of single follicular unit extract (FUE) grafting to heal chronic ulcers of intermediate RDEB in a 54-year-old woman with extensive chronic wounds covering around 30% of the body surface area. On Day 17 post first graft session, the area of treated ulcers on her right upper back was reduced by 80%. Immunofluorescence study revealed positive type VII collagen expression along the epidermal and follicular basement membrane zone in the donor and recipient sites. A few grafted follicles continued to grow hair on the recipient sites. A total of 360 FUEs were grafted in nine sessions over five years, resulting in healing of most treated ulcers and reduced significantly her time for daily wound dressing. Importantly, FUE grafting using patient's own scalp follicles does not require any laboratory manipulation. It is safe and easy to perform. Autologous follicular grafting appears efficacious for healing of recalcitrant wounds and provides an innovative solution for RDEB patients with such wounds.

BACKGROUND AND OBJECTIVES: Dissecting folliculitis (DF) or dissecting cellulitis of the scalp is regarded as a rare disease with disfiguring scarring alopecia. This study aimed to analyze the features of DF and to propose a classification to define its severity. PATIENTS AND METHODS: A hospital-based retrospective study was conducted. Patients with a histopathological diagnosis or clinical features leading to diagnosis of DF were included and classified into three stages. RESULTS: Among the 66 patients recruited (63 men / 3 women, mean age 24.9 years), multiple interconnected alopecic nodules involving the vertex scalp were the main feature. Histopathology showed an extensive inflamed granulation abscess forming a dissection plane in the lower dermis/subcutis in the acute stage. Lymphocytic infiltration was predominant in seven of 21 histology specimens. Overweight and obesity were noted in 29 of 45 patients examined. No association with smoking was found. There was comorbidity with acne conglobata in 15 of 66 patients, two of whom had acne inversa. Longer disease duration and greater number of nodules were associated with higher severity of DF (p < 0.05). A complete remission rate of 25 % was achieved by any treatment, and a rate of 37.5 % was achieved with oral isotretinoin alone. CONCLUSIONS: DF is not uncommon in Taiwan. An association with obesity needs to be clarified.

In addition to genetics and androgens, novel factors could play a role in androgenetic alopecia (AGA). This study aims to investigate the association between plasma leptin level with the risk and severity of AGA in men. Forty-eight subjects were enrolled including 29 AGA and 19 non-AGA subjects. The plasma leptin level was significantly higher in AGA subjects, compared to non-AGA subjects (4.45 vs 2.76 ng/mL, P<.05). A higher plasma leptin levels were positively correlated with the risk of developing AGA in multivariate logistic analysis (odds ratio=2.77, P<.05). Leptin from the circulation might impact the development of AGA.

Adipose tissue encircles the lower portion of anagen hair follicles and may regulate hair cycle progression. As leptin is a major adipokine, its level of expression from the dermal white adipose tissue during hair cycle progression was studied. The result shows that leptin level is differentially expressed during hair cycle, the lowest in early anagen phase, upregulated in late anagen phase and the highest in the telogen phase. On the other hand, leptin receptor is detected in keratin 15-positive hair bulge epithelium of both anagen- and telogen-phase hair follicles of mice pelage and vibrissa hair, and hair from human scalp. Leptin contributes to adipocyte-mediated growth inhibition of anagen-phase vibrissa hair as demonstrated in organ culture and coculture system. Our data suggest that leptin of dermal white adipose tissue might regulate hair growth and, therefore, hair cycle progression via leptin receptor on the hair follicle epithelium.

BACKGROUND: Obesity is a risk factor for multiple health problems, but its association with androgenetic alopecia (AGA) remains controversial. OBJECTIVE: We sought to determine the association between body mass index (BMI) and alopecia severity in men with AGA and early-onset AGA. METHODS: A cross-sectional study was conducted. The medical charts and photographs of men with a clinical diagnosis of AGA were reviewed. RESULTS: In all, 189 men were enrolled with a mean age of 30.8 years. In male-pattern AGA (n = 142), men with severe alopecia (grade V-VII) had higher BMI than those with mild to moderate alopecia (grade I-IV) (25.1 vs 22.8 kg/m(2), P = .01). After multivariate adjustments, the risk for severe alopecia was higher in the overweight or obese (BMI ≥24 kg/m(2)) subjects with male-pattern AGA (odds ratio 3.52, P < .01). In early-onset male-pattern AGA (n = 46), the risk for having severe alopecia was also higher in the overweight or obese subjects (odds ratio 4.97, P = .03). LIMITATIONS: Parameters used to evaluate obesity were limited because of the retrospective nature of the study. CONCLUSIONS: Higher BMI was significantly associated with greater severity of hair loss in men with male-pattern AGA, especially in those with early-onset AGA.

Objectives: Invasive fungal spondylodiscitis (IFSD) is rare and could be lethal in certain circumstances. The previous literature revealed limited data concerning its outcomes. This study aimed to establish a risk-scoring system to predict the one-year mortality rate of this disease. Methods: A total of 53 patients from a multi-centered database in Taiwan were included in this study. All the clinicopathological and laboratory data were retrospectively analyzed. Variables strongly related to one-year mortality were identified using a multivariate Cox proportional hazards model. A receiver operating characteristic (ROC) curve was used to express the performance of our IFSD scoring model. Results: Five strong predictors were included in the IFSD score: predisposing immunocompromised state, the initial presentation of either radiculopathy or myelopathy, initial laboratory findings of WBC > 12.0 or <0.4 103/µL, hemoglobin < 8 g/dL, and evidence of candidemia. One-year mortality rates for patients with IFSD scores of 0, 1, 2, 3, and 4 were 0%, 16.7%, 56.3%, 72.7%, and 100%, respectively. The area under the curve of the ROC curve was 0.823. Conclusions: We developed a practical scoring model with easily obtained demographic, clinical, and laboratory parameters to predict the probability of one-year mortality in patients with IFSD. However, more large-scale and international validations would be necessary before this scoring model is commonly used.
RESUMO
Acne keloidalis is a primary scarring alopecia characterized by longstanding inflammation in the scalp causing keloid-like scar formation and hair loss. Histologically, acne keloidalis is characterized by mixed leukocytic infiltrates in the acute stage followed by a granulomatous reaction and extensive fibrosis in the later stages. To further explore its pathogenesis, bulk RNA sequencing, single-cell RNA sequencing, and spatial transcriptomics were applied to occipital scalp biopsy specimens of lesional and adjacent no-lesional skin in patients with clinically active disease. Unbiased clustering revealed 19 distinct cell populations, including 2 notable populations: POSTN+ fibroblasts with enriched extracellular matrix signatures and SPP1+ myeloid cells with an M2 macrophage phenotype. Cell communication analyses indicated that fibroblasts and myeloid cells communicated by SPP1 signaling networks in lesional skin. A reverse transcriptomics in silico approach identified corticosteroids as possessing the capability to reverse the gene expression signatures of SPP1+ myeloid cells and POSTN+ fibroblasts. Intralesional corticosteroid injection greatly reduced SPP1 and POSTN gene expression as well as acne keloidalis disease activity. Spatial transcriptomics and immunofluorescence staining verified microanatomic specificity of SPP1+ myeloid cells and POSTN+ fibroblasts with disease activity. In summary, the communication between POSTN+ fibroblasts and SPP1+ myeloid cells by SPP1 axis may contribute to the pathogenesis of acne keloidalis.

Psoriasis, a chronic, multisystemic inflammatory disease affecting millions of people globally, manifests as erythematous, thick, scaly plaques on the skin. Clinical evaluation remains to be the benchmark for diagnosis and monitoring of this debilitating disease. With current advancements in targeted molecular therapy for psoriasis such as biologics, molecular detection methods may also help guide clinical decisions and therapeutic strategies through quantification of circulating biomarkers, which could reflect the underlying pathogenic events happening at a certain point of the disease course. In this review, we will discuss how biomarkers are detected in serum samples using enzyme-linked immunosorbent assay (ELISA). This review will feature candidate biomarkers supported by clinical data for psoriasis including, but not limited to, cytokines, chemokines, adipokines, and antimicrobial peptides. A better understanding of the common method used for biomarker detection would enable physicians to interpret and correlate laboratory results with the disease pathogenesis and clinical outcomes, e.g., severity assessment and/or therapeutic response. With better health outcomes as the main goal, the utility of such information to evaluate and even predict treatment response would be a major step closer towards patient-tailored management.
RESUMO
Previous studies have shown how adipocytes can modulate the activity of hair follicle stem cells. However, the role of adipocytes in the pathogenesis of androgenetic alopecia (AGA) remains unknown. We aimed to determine signaling pathways related to the adipose tissue changes in the human scalp with AGA through RNA-seq analysis. RNA was isolated from the adipose tissues derived from the bald (frontal) and normal (occipital) scalps of male patients with AGA (n = 4). The pooled RNA extracts from these samples were subjected to RNA sequencing, followed by differential gene expression and pathway analysis. Our gene expression analysis identified 1,060 differentially expressed genes, including 522 upregulated and 538 downregulated genes in the bald AGA scalp. Biological pathways pertaining to either adipose tissue metabolism or the hair cycle were generated in our pathway analysis. Downregulation of the peroxisome proliferator-activated receptor (PPAR) signaling pathway was noted to be significant in the bald scalp. Expression of adipogenic markers (e.g., PPARG, FABP4, PLN1, and ADIPOQ) was also decreased in the bald site. These findings imply that adipogenesis becomes downregulated in AGA, specifically within the bald scalp adipose. Our results lead to the hypothesis that PPARγ-mediated adipogenesis in the scalp adipose, via crosstalk with signaling pathways involved in hair cycling, might play a role in AGA.
RESUMO
In this study, we investigated a novel approach to fabricate multifunctional ionic gel sensors by using deep eutectic solvents (DESs) as replacements for water. When two distinct DESs were combined, customizable mechanical and conductive properties were created, resulting in improved performance compared with traditional hydrogel-based strain sensors. DES ionic gels possess superior mechanical properties, transparency, biocompatibility, and antimicrobial properties, making them suitable for a wide range of applications such as flexible electronics, soft robotics, and healthcare. We conducted a comprehensive evaluation of the DES ionic gels, evaluating their performance under extreme temperature conditions (-70 to 80 °C), impressive optical transparency (94%), and biocompatibility. Furthermore, a series of tests were conducted to evaluate the antibacterial performance (Escherichia coli) of the DES ionic gels. Their wide strain (1-400%) and temperature (15-50 °C)-sensing ranges demonstrate the versatility and adaptability of DES ionic gels for diverse sensing requirements. The resulting DES ionic gels were successfully applied in human activity and vital sign monitoring, demonstrating their potential for biointegrated sensing devices and healthcare applications. This study offers valuable insights into the development and optimization of hydrogel sensors, particularly for applications that require environmental stability, biocompatibility, and antibacterial performance, thereby paving the way for future advancements in this field.

Annular configuration is conspicuous in the clinical manifestation of many skin diseases and can be helpful for the diagnosis and differential diagnosis. Variations may include arciform, ring-form, annular, circinate, serpiginous, gyrated, polycyclic, targeted or figurate forms, in different colors, sizes, and numbers, with various textures and surfaces. In infectious dermatoses, the annular reactions can be specific or nonspecific, while the underlying mechanisms remain largely unknown. In the specific reactions caused by direct invasion of the pathogens, the contest between the centrifugal outspread of the infectious agents and the centripetal impedance of the host immune response is supposed to determine the final conformation. Examples include erythema infectiosum, orf, erythema multiforme, and pityriasis rosea of viral origin. Bacterial infections that may display annular lesions include erythrasma, erythema (chronicum) migrans of Lyme borreliosis, secondary syphilis, cutaneous tuberculosis, and leprosy. Superficial mycosis, such as dermatophytosis, candida intertrigo, tinea imbricata, and subcutaneous mycosis, such as chromoblastomycosis, and algae infection protothecosis, are characterized by annular progression of the skin lesions. The creeping serpiginous extension is an alarming sign for the diagnosis of cutaneous larva migrans. A better understanding of the virulence and pathogenicity of the pathogens and the way and type of immune response will help to clarify the pathogenesis.

Acute rheumatic fever (ARF) is considered as a disorder of children, and attacks in adults are usually a recurrence of disease acquired in the child's life. Although the incidence of ARF in children has a decreasing trend in developed countries, resurgent and sporadic epidemics still occur in adults. The first attacks of ARF in adult patients without a childhood history can lead to a diagnostic dilemma. A medical record review in adults at least 18 years of age with an arthralgia complaint fulfilling 2015 revised Jones criteria was performed from January 1, 2000 to December 31, 2019. Eleven ARF patients were identified, including 8 with initial attacks (6 females aged 26-42 years, 33.9 ± 5.3) and 3 pre-existing valvular heart disease with recurrent attacks (2 females aged 38-52 years, 45.0 ± 7.0). In addition to febrile pharyngitis and migratory polyarthritis in initial attacks, pericarditis was encountered in 1, valvulitis in 2, prolong PR interval in 3 and skin involvement in 2 patients with erythema marginatum and IgA vasculitis. All responded to antibiotics and nonsteroidal anti-inflammatory drugs therapy with normalized clinical and laboratory abnormalities, no new-onset carditis, and no recurrent disease during a long-term follow-up (3.8-19.8 years, 12.7 ± 5.4). A sporadic occurrence of adult ARF is observed in southern Taiwan. This disease should be considered by physicians for the differential diagnosis of febrile pharyngitis with arthritis and/or carditis in adults, even in areas with a low incidence of ARF.

In clinical settings, although Psoriasis Area and Severity Index (PASI) scoring system can provide a quick visual assessment of the severity of psoriasis vulgaris, there is still a strong demand for higher efficiency and accuracy in quantifying the inflammation status of psoriatic lesions. Currently, there are already commercial systems, such as the Courage + Khazaka Corneometer and Mexameter that measure skin capacitance and optical reflectance, for conveniently quantifying the status of skin barrier function and erythema of skin. Despite numerous comparisons of the Courage + Khazaka system with the PASI scoring system, they are rarely compared on parity with diffuse reflectance spectroscopy (DRS) based systems. In this study, we employed a custom-built DRS system shown to be able to determine the skin water-protein binding status and the hemoglobin concentration, and we performed cross-validation of the DRS measurement results with the readings derived from the Corneometer and Mexameter as well as a portion of the PASI scores. Our results revealed that the erythema readings from the Mexameter were a good representation of skin oxygenated hemoglobin but not the deoxygenated hemoglobin. On the other hand, the dermatologists recruited in this study were inclined to rate higher scores on the "erythema" category as skin's deoxygenated hemoglobin level was higher. Thus, the Mexameter derived erythema readings may not be coherent with the PASI erythema scores. Further, the Corneometer derived skin capacitance readings were well correlated to the PASI "desquamation" and "thickness" scores, while the PASI "desquamation" evaluation was a dominating factor contributing to the DRS deduced water-protein binding status. We conclude that the DRS method could be a valuable addition to existing skin capacitance/reflectance measurement systems and the PASI scoring system toward achieving a more efficient and objective clinical psoriasis vulgaris severity evaluation.

OBJECTIVE: Endoscopic lumbar discectomy has been an alternative for treating lumbar disc herniation. Evidence-based study for the benefit zone of full-endoscopic lumbar discectomy (FELD) is necessary. The study compared the complication risks between the FELD and open discectomy or microdiscectomy. METHODS: The literature search was from 4 online databases for randomized controlled trials (RCTs) and cohort studies. The meta-analysis of different study designs was conducted separately. Complication rates were considered primary outcomes, and the recurrence and revision rates were considered secondary outcomes. RESULTS: Six RCTs and thirteen cohort studies met the eligibility criteria. The meta-analysis was conducted separately. From the pooled RCT meta-analysis, the overall complication rates of FELD and open discectomy/microdiscectomy were 5.5% and 10.4%, respectively. The moderate-quality evidence suggested that FELD had a lower risk of overall complications (risk ratio [RR] = 0.55, 95% confidence interval [CI] = 0.31-0.98). There was no significant difference in specific complications and recurrence. The analysis of cohort studies revealed no significant difference in overall complications, but there was significant heterogeneity in the results. The risk of dural injury was significantly lower for FELD (RR = 0.46, 95% CI = 0.22-0.96). The pooled meta-analysis from cohort studies suggested a higher risk of transient dysesthesia (RR = 3.70, 95% CI = 1.54-8.89), residual fragment (RR = 5.29, 95% CI = 2.67-10.45), and revision surgeries (RR = 1.53, 95% CI = 1.12-2.08) for FELD. CONCLUSIONS: The current evidence showed a lower risk of overall complications for FELD. The quality of evidence was moderate to low, and the risk of bias from the primary literature should be concerned.
