RESUMO
INTRODUCTION: Atopic dermatitis (AD) is a disease frequently occurring in children. The immune response is characterized by T-helper (Th)-2-dependent inflammation. Type 1 diabetes mellitus (T1DM) is an autoimmune disease that destroys pancreatic islet beta cells. In contrast, it is mainly mediated by a Th-1-dependent response. An inverted association has been hypothesized between T1DM and AD since Th1 and Th2 responses are mutually inhibitory. METHODS: Data was retrieved from a nationwide healthcare database in Taiwan. A logistic regression model was used to evaluate the association of T1DM in patients with AD within a year. A Cox proportional hazards analysis was used to evaluate the subsequent risk of developing T1DM 1 year after AD diagnosis. RESULTS: We identified 396,461 patients with AD and 1,585,844 age- and sex-matched controls. During the first year of follow-up, after adjusting variates, the association between T1DM and AD showed no statistical differences (odds ratio: 1.40; 95% confidence interval [CI]: 0.83-2.38, p = 0.207). After excluding those T1DM cases within 1 year of AD diagnosis and those with a follow-up duration of less than 1 year, AD did not significantly increase the risk of T1DM (hazard ratio [HR]: 1.02; 95% CI, 0.83-1.25, p = 0.843). CONCLUSIONS: Our study revealed that there was no significant association between AD and T1DM in the first year after AD diagnosis, and there was no increased risk of T1DM in AD patients in the average 5-year follow-up in our study.

BACKGROUND: Vitiligo is reportedly associated with several ocular abnormalities. However, the relationship between vitiligo and retinal detachment (RD) remains unclear. OBJECTIVES: To examine the risk of RD in patients with vitiligo. METHODS: A nationwide population-based cohort study was conducted using data from the Taiwan National Health Insurance Database from 2007 to 2018. A total of 21 132 patients with vitiligo were matched in a 1 : 4 ratio with people without vitiligo by age, sex and comorbidity propensity score. Cumulative incidence and Cox proportional hazard models were used to investigate the risk of RD in patients with vitiligo. Subgroup analysis was performed. RESULTS: The cohort with vitiligo had a significantly higher rate of RD than the cohort without vitiligo [adjusted hazard ratio (aHR) 1.44, 95% confidence interval (CI) 1.20-1.72; P < 0.001]. Patients with vitiligo who required treatments such as phototherapy, systemic corticosteroids or immunosuppressants exhibited an even greater risk of RD (aHR 1.57, 95% CI 1.16-2.14; P = 0.004). CONCLUSIONS: Our study revealed a 1.44-fold increased risk of RD in patients with vitiligo, with an even higher risk in patients receiving phototherapy, systemic corticosteroids or immunosuppressants. The risk remained consistently higher over a 10-year follow-up period.

During embryogenesis, basic fibroblast growth factor (bFGF) is released from neural tube and myotome to promote myogenic fate in the somite, and is routinely used for the culture of adult skeletal muscle (SKM) stem cells (MuSC, called satellite cells). However, the mechanism employed by bFGF to promote SKM lineage and MuSC proliferation has not been analyzed in detail. Furthermore, the question of if the post-translational modification (PTM) of bFGF is important to its stemness-promoting effect has not been answered. In this study, GST-bFGF was expressed and purified from E.coli, which lacks the PTM system in eukaryotes. We found that both GST-bFGF and commercially available bFGF activated the Akt-Erk pathway and had strong cell proliferation effect on C2C12 myoblasts and MuSC. GST-bFGF reversibly compromised the myogenesis of C2C12 myoblasts and MuSC, and it increased the expression of Myf5, Pax3/7, and Cyclin D1 but strongly repressed that of MyoD, suggesting the maintenance of myogenic stemness amid repressed MyoD expression. The proliferation effect of GST-bFGF was conserved in C2C12 over-expressed with MyoD (C2C12-tTA-MyoD), implying its independence of the down-regulation of MyoD. In addition, the repressive effect of GST-bFGF on myogenic differentiation was almost totally rescued by the over-expression of MyoD. Together, these evidences suggest that (1) GST-bFGF and bFGF have similar effects on myogenic cell proliferation and differentiation, and (2) GST-bFGF can promote MuSC stemness and proliferation by differentially regulating MRFs and Pax3/7, (3) MyoD repression by GST-bFGF is reversible and independent of the proliferation effect, and (4) GST-bFGF can be a good substitute for bFGF in sustaining MuSC stemness and proliferation.

BACKGROUND: There is growing evidence that patients with alopecia areata (AA) have an increased risk of developing psychiatric comorbidities. However, the relationship between AA and suicidal behaviors remains unclear. OBJECTIVE: The objective of this study was to investigate the association between AA and suicidal behaviors. METHODS: Participants were recruited from the National Health Insurance Research Database in Taiwan, including 10,515 patients with AA and 10,5150 matched controls, to assess the risk of suicide attempts. A Cox regression model was used for all analyses. RESULTS: Compared with the controls, an increased risk of suicide attempts was observed in patients with AA, with an adjusted hazard ratio of 6.28 (95% confidence interval, 4.47-8.81). Suicide risk remained significantly elevated in AA patients when stratified by underlying psychiatric disorders. The mean age of initial suicidal behaviors was also lower in patients with AA. CONCLUSIONS: Patients with AA had a significantly higher incidence of suicidal attempts than controls, regardless of concurrent psychiatric illness. Further studies are needed to elucidate the pathophysiology of the association between AA and suicidality. In addition, dermatologists should be aware of the increased suicidality of patients with AA.

Patients with bullous pemphigoid are susceptible to serious infections, which are the leading cause of death in these patients. The aims of this population-based cohort study were to investigate the incidence and spectrum of serious infections in patients with bullous pemphigoid and to identify associated risk factors. The outcome measure was any infection requiring hospitalization. Hazard ratios with 95% confidence intervals were estimated using subdistribution hazard models. In total, 12,300 patients with bullous pemphigoid and 49,200 matched controls were identified through the National Health Insurance Research Database in Taiwan. Within 2 years of bullous pemphigoid diagnosis, 5,006 (40.7%) patients developed serious infections, with an incidence of 385.5/1,000 person-years. Patients with bullous pemphigoid were twice as likely to develop serious infections as controls (adjusted hazard ratio, 2.01; 95% confidence interval 1.92-2.10). Systemic corticosteroid use was the strongest risk factor, resulting in a 2-fold increase in the risk for serious infections. Other independent risk factors were advanced age, female sex, low income, and certain comorbidities. In conclusion, this study demonstrated an increased risk of serious infections following a diagnosis of bullous pemphigoid. Prophylaxis of serious infections through active intervention with the risk factors may be essential in reducing the morbidity and mortality associated with bullous pemphigoid.

Background: Proton-pump inhibitors (PPI) are among the most widely used drugs worldwide. However, the association between PPI use and the risk of asthma remains unclear. Objective: To investigate the association between PPI use and subsequent asthma risk. Methods: We included participants from the Taiwan National Health Insurance Research Database between 1999 and 2013. Patients who used PPIs and experienced new-onset asthma (n = 20,344) were assigned to the case cohort and matched in a 1:1 ratio with controls who did not subsequently develop asthma. PPI use was defined as > 30 cumulative defined daily doses (cDDD); non-PPI use was defined as ≤ 30 cDDDs. The Charlson Comorbidity Index (CCI) score was used for clinical prognosis and comorbidity adjustment. Multivariate Cox regression models were used for the calculation of adjusted odds ratios (OR). Results: There was a significant and dose-dependent association between PPI use and the risk of developing asthma. The adjusted ORs were 1.24 (95% confidence interval [CI], 1.15-1.33), 1.39 (95% CI, 1.28-1.50), and 1.61 (95% CI, 1.43-1.81) for the male subject with 31-120 cDDDs, 120-365 cDDDs, and >365 cDDDs, respectively, compared with PPI nonusers. Men were at higher risk of developing asthma with longer PPI use compared with women. Stratified analyses based on the PPI type showed that exposure to lansoprazole, pantoprazole, omeprazole, and esomeprazole was associated with subsequent asthma risk. Conclusion: Extended use of PPIs was found to be linked to an increased risk of asthma development. This association remained consistent across different age groups, sexes, demographic factors, indications for PPI use, CCI scores, and other atopic diseases. However, further prospective studies are required to elucidate the causal mechanisms involved.

BACKGROUND: Studies have shown that bullous pemphigoid (BP) occurs in patients with chronic kidney disease (CKD). However, the risk of developing BP in patients with CKD remains inconclusive. OBJECTIVE: To investigate whether CKD increases the risk of BP. METHODS: Participants were recruited from the National Health Insurance Database of Taiwan between 2007 and 2018. Overall, 637,664 newly diagnosed patients with CKD and 637,664 age-, sex-, and comorbidity-matched non-CKD participants were selected. A competing risk model was used to evaluate the risk of development of BP. RESULTS: After adjusting for age, sex, and comorbid diseases in the multivariate model, CKD was a significant risk factor for BP (adjusted hazard ratio [aHR]: 1.29; 95% confidence interval [CI]: 1.17-1.42; p < 0.001). CKD patients were classified into the dialytic or non-dialytic groups and compared to non-CKD participants, and this revealed that patients with dialysis-dependent CKD had the highest risk of BP (aHR 1.75; 95% CI 1.51-2.03), followed by patients with non-dialysis-dependent CKD (aHR 1.20; 95% CI 1.08-1.32). LIMITATIONS: We lacked detailed laboratory data on the severity of CKD. CONCLUSIONS: Compared with individuals without CKD, those with CKD had a 1.3-fold increased risk of BP. Patients with dialysis-dependent CKD had an even higher BP risk (1.8-fold).

Dupilumab interferes with the signaling pathways of IL-4 and IL-13 and is effective in treating atopic dermatitis. Specific genodermatoses, including Netherton syndrome, epidermolysis bullosa pruriginosa, and hyper-IgE syndrome, are Th2 skewed diseases with activation of type 2 inflammation. We performed this systematic review to investigate the therapeutic role of dupilumab in the treatment of genodermatosis. A systematic search was conducted of the PubMed, Embase, Web of Science, and Cochrane databases from inception to December 13, 2021. The review included studies with relevant terms including "dupilumab," "genodermatosis", "Netherton syndrome", "ichthyosis", "epidermolysis bullosa" and "hyper-IgE syndrome". The initial search yielded 2,888 results, of which 28 studies and 37 patients with genodermatosis were enrolled. The assessed genodermatoses included Netherton syndrome, epidermolysis bullosa pruriginosa, hyper-IgE syndrome, Hailey-Hailey disease, and severe eczema associated with genetic disorders. Most of the reported cases showed significant clinical improvement after the initiation of dupilumab treatment without major adverse events. Decreased immunoglobulin E levels and cytokine normalization have also been documented. In conclusion, Dupilumab may have a potential therapeutic role in certain genodermatoses skewed towards T helper 2 (Th2) immunity, including Netherton syndrome, epidermolysis bullosa pruriginosa, hyper-IgE syndrome, Hailey-Hailey disease, and severe eczema associated with some genetic disorders.

BACKGROUND: Growing evidence has revealed abnormalities in the retinal structures of patients with alopecia areata (AA). However, the relationship between AA and retinopathy remains unclear. OBJECTIVE: To investigate the association between AA and retinal diseases. METHODS: The study participants were recruited from the National Health Insurance Research Database in Taiwan. We included 9909 patients with AA and 99,090 matched controls to assess the risk of retinal diseases. A Cox regression model was used for all analyses. RESULTS: Compared with the controls, patients with AA had an adjusted hazard ratio (aHR) of 3.10 (95% confidence interval [CI] 2.26-4.26) for retinal diseases. With respect to individual retinal diseases, Patients with AA had significantly higher risks of developing retinal detachment (aHR 3.98; 95% CI 2.00-7.95), retinal vascular occlusion (aHR 2.45; 95% CI 1.22-4.92), and retinopathy (aHR 3.24; 95% CI 2.19-4.81) than controls. LIMITATIONS: This was a retrospective cohort study. Meanwhile, almost all the participating individuals were residents of Taiwan; therefore, the validity of our findings in other demographics remains unclear. CONCLUSION: Patients with AA had a significantly higher risk of retinal disease than controls. Further studies are needed to clarify the pathophysiology of AA and retinal diseases.

BACKGROUND: The concurrent incidence of autoimmune comorbidities in obsessive-compulsive disorder (OCD) is known. However, the association between OCD and related autoimmune skin diseases (ASDs) has not been well studied. OBJECTIVE: This study aimed to investigate the association between OCD and the risk of ASDs. METHODS: To assess the risk of developing ASDs, we recruited 44 324 patients with OCD and 177 296 matched controls from the National Health Insurance Research Database in Taiwan. A Cox regression model was used for the analyses. RESULTS: After adjusting for confounders, an increased risk of ASDs among the patients with OCD (adjusted hazard ratio [aHR]: 6.36; 95% confidence interval [CI]: 5.43-7.45) was found when compared to the controls. Statistically significant associations were found between OCD and seven individual ASDs, including psoriasis (aHR: 12.52; 95% CI: 8.78-17.85), lichen planus (aHR: 27.22; 95% CI: 13.09-56.60), alopecia areata (aHR: 13.69; 95% CI: 9.38-19.98), autoimmune bullous diseases (aHR: 4.30; 95% CI: 2.03-9.11), hidradenitis suppurativa (aHR: 29.95; 95% CI: 3.35-267.62), vitiligo (aHR: 9.35; 95% CI: 5.35-16.32), and lupus erythematosus (aHR: 2.10; 95% CI: 1.52-2.91). CONCLUSIONS: Patients with OCD had an increased risk of developing ASDs compared to matched controls. Further studies are required to clarify the underlying mechanisms.
RESUMO
Large-scale, real-world studies on the side effects of systemic therapies (including biologics) in patients with psoriasis are limited. We aimed to calculate the risk of malignancy in patients with psoriasis who were treated with systemic medications. Nested case-control analyses were performed among psoriasis patients without a history of malignancy. We recruited 4188 patients with newly diagnosed psoriasis and successive malignancies, and 8376 matched controls from the National Health Insurance Research Database in Taiwan. The therapy duration was within 5 years before malignancy onset and further stratified into two groups according to the duration of medication usage. Multivariate conditional logistic regression adjusted for potential confounders was used to estimate malignancy risk associated with systemic treatments. Among psoriasis patients, long-term (> 12 months) treatment with cyclosporine increased the risk of malignancy compared with no exposure (odds ratio, 1.57; p = 0.01). Short-term (≤ 12 months) or long-term (> 12 months) use of other systemic treatments, including methotrexate, azathioprine, systemic retinoids, mycophenolate mofetil, sulfasalazine, etanercept, adalimumab, and ustekinumab, was not associated with an increased risk of malignancy in patients with psoriasis. Long-term treatment with cyclosporine increased the risk of malignancy in patients with psoriasis by 1.57-fold.

BACKGROUND: Up to 25% of patients with cutaneous lupus erythematosus (CLE) can develop systemic lupus erythematosus (SLE). However, the risk of autoimmune diseases other than SLE in CLE patients who have only skin manifestations (CLE-alone) has rarely been explored. OBJECTIVE: To investigate the long-term risk and independent factors of non-SLE autoimmune diseases among CLE-alone patients. METHOD: A nationwide cohort study using the Taiwanese National Health Insurance Research Database 1997-2013. CLE patients and matched subjects were included. Cumulative incidences of autoimmune diseases after 1 year of CLE-alone diagnosis were compared. Cox proportional hazard model was also performed. RESULTS: A total of 971 CLE-alone patients and 5,175 reference subjects were identified. The 10-year cumulative incidence of autoimmune diseases other than SLE was significantly elevated in the CLE-alone cohort (9.00%, 95% confidence interval [CI] 6.72-11.29) than in the reference cohort (4.20%, 95% CI 3.53-4.87%) (p < 0.001). CLE-alone was independently associated with non-SLE autoimmune diseases (adjusted hazard ratio 1.55, 95% CI 1.10-2.18). Among CLE-alone patients, females and those taking long-term systemic corticosteroids (a proxy for extensive disease) were associated with non-SLE autoimmune diseases after adjusting for the number of repeated autoimmune laboratory tests. CONCLUSION: CLE-alone is independently associated with future non-SLE autoimmune diseases.

BACKGROUND: Bullous pemphigoid (BP) is a common autoimmune blistering skin disease with substantial mortality. OBJECTIVE: To identify whether the use of immunosuppressants was associated with reduced mortality in BP patients. METHODS: The data for this study were obtained from the National Health Insurance Research Database in Taiwan from January 1, 1997 to December 31, 2013. Those BP patients receiving any immunosuppressant for ≥28 days per month for 3 consecutive months were defined as the immunosuppressant cohort. In total, 452 BP patients on immunosuppressants were matched 1:4 by age, sex, propensity score of comorbidities, and use of tetracycline with 1,808 BP patients taking only corticosteroids. RESULTS: The immunosuppressant cohort had a significantly lower 5-year mortality rate than the corticosteroid cohort (0.57 vs. 0.67). In the multivariable regression analysis adjusted for covariates, the use of immunosuppressants significantly reduced the risk of mortality (hazard ratio [HR]: 0.78, 95% confidence interval [CI]: 0.68-0.90, p < 0.001). Hyperlipidemia also reduced risk of mortality. However, age, diabetes, renal disease, chronic obstructive pulmonary disease, cerebrovascular disease, and dementia were significant risk factors for mortality. In the subgroup analysis, the risk of mortality decreased most substantially in those aged <70 years (HR: 0.45, 95% CI: 0.28-0.72). CONCLUSION: Immunosuppressant use was associated with a 22% reduced risk of BP mortality. The effects were more substantial in those aged <70 years, with a 55% reduced risk of mortality.

BACKGROUND: Vitiligo is a skin depigmentation disorder that results from the autoimmune destruction of cutaneous melanocytes. Several ocular abnormalities, including uveitis, dry eye, glaucoma, and retinal diseases, have been reported in patients with vitiligo. The aim of our study was to investigate the association of ocular abnormalities with vitiligo. METHODS: This meta-analysis was registered in PROSPERO (CRD42021224167) and adhered to MOOSE checklist and PRISMA guidance for all processes. PubMed, Embase, Web of Science, and Cochrane databases were searched for studies examining the association between ocular abnormalities and vitiligo from inception to December 10, 2020. Studies recruiting patients with Sjogren's syndrome or Vogt-Koyanagi-Harada syndrome were excluded. The primary outcomes were the Schirmer test, tear film break-up time (TBUT), and ocular surface disease index (OSDI) of vitiligo patients compared to the controls. The risk of bias of the selected studies was assessed using the Newcastle-Ottawa Scale (NOS) of case-control studies. RESULTS: This meta-analysis of 16 case-control studies showed that patients with vitiligo had significantly lower Schirmer test values (mean difference [MD], -1.65; 95% CI, -2.81 to -0.49), shorter TBUTs (MD, -4.66; 95% CI, -7.05 to -2.26), higher ocular surface disease indices (MD, 18.02; 95% CI, 5.7-30.35), and thinner subfoveal choroidal thicknesses (MD, -53.10; 95% CI, -69.84 to -36.36). No significant differences were found in the prevalence of glaucoma and the level of intraocular pressure. CONCLUSIONS: Our study supports an association between dry eye and thinner subfoveal choroidal thickness in patients with vitiligo. Dermatologists should be aware of these possible comorbidities and refer vitiligo patients with ocular symptoms to ophthalmologists for further management.

BACKGROUND: Psoriasis is a chronic inflammatory skin disease with potential systemic involvement. Some evidence suggests an increased risk of dry eye in patients with psoriasis. However, the relationship between these two conditions remains unclear. The aim of our study is to investigate the association between psoriasis and dry eye disease. METHODS: This meta-analysis was registered in PROSPERO (CRD42020199445) and adhered to MOOSE checklist and PRISMA guidance for all processes. PubMed, Embase, Web of Science, and Cochrane databases were searched for studies examining the association between psoriasis and dry eye disease from inception to December 13, 2020. The primary outcome was the prevalence of dry eye disease in patients with psoriasis relative to controls. The secondary outcomes were the Schirmer I test score, tear film breakup time (TBUT), and ocular surface disease index (OSDI). The risk of bias of the selected studies was assessed using the Newcastle-Ottawa Scale. RESULTS: The meta-analysis showed a significant association between dry eye disease and psoriasis (OR, 8.49; 95% CI, 3.34-21.58). Moreover, patients with psoriasis had a significantly lower Schirmer I test score (MD, -2.80; 95% CI, -4.07 to -1.52), shorter TBUT (MD, -4.12; 95% CI, -5.22 to -3.02), and higher OSDI (MD, 20.15; 95% CI, 6.24-34.05; p < 0.01), compared to controls. CONCLUSIONS: The current evidence supports an association between dry eye disease and psoriasis. These results suggest ophthalmologic assessment for the early recognition and management of dry eye in patients with psoriasis.

BACKGROUND: Sodium-glucose co-transporter 2 inhibitor (SGLT2i) treatment may exert anti-inflammatory effects by modulating the NOD-like receptor family pyrin domain-containing 3 inflammasome and interleukin-17/23 inflammatory axis, which are both involved in the pathogenesis of psoriasis. However, the relationship between SGLT2i treatment and psoriasis remains unclear. AIM: To investigate the association between SGLT2i treatment and incident psoriasis. METHODS: Using the Taiwan National Health Insurance Database for the period 2007-2018, we matched 103 745 patients with Type 2 diabetes mellitus (T2DM) receiving SGLT2i with a control group of patients with T2DM who did not use SGLT2i, matching them in a 1 : 2 ratio by age, sex, diabetes duration, insulin use and comorbidities, and evaluating the psoriasis risk in both groups. RESULTS: The incident psoriasis risk did not significantly differ between the SGLT2i and control groups [hazard ratio (HR) = 1.24, 95% CI 0.95-1.64] after adjustment for potential confounders. Insulin use (HR = 1.65, 95% CI 1.24-2.19) and chronic liver disease and cirrhosis (HR = 1.34, 95% CI 1.01-1.77) were significantly associated with increased psoriasis risk. A slightly increased psoriasis risk was also detected in certain SGLT2i user subgroups, especially those with renal disease (HR = 2.73, 95% CI 1.45-5.13). CONCLUSION: SGLT2i-mediated protective effects in psoriasis could not be established. SGLT2i treatment increased psoriasis risk by 2.7-fold in patients with T2DM exhibiting renal diseases.

BACKGROUND: Alopecia areata (AA) and irritable bowel syndrome (IBS) are two distinct diseases that share a similar pathophysiology; however, the relationship between these two diseases is unknown. This study aimed to investigate the bidirectional relationship between AA and IBS. METHODS: Participants were recruited from the National Health Insurance Research Database in Taiwan. We included 5446 patients with AA and 21 784 matched controls to assess the risk of IBS, and 56 429 patients with IBS and 225 716 matched controls to assess the risk of AA. The Cox proportional-hazards regression model was used to calculate the adjusted hazard ratio (aHR). RESULTS: After adjustment for potential confounders, patients with AA had an aHR of 5.20 [95% confidence interval (CI) 3.97-6.82] for IBS in comparison with the controls. Furthermore, compared with the controls, IBS patients had an aHR of 5.38 (95% CI 3.95-7.34) for AA. CONCLUSION: AA is bidirectionally associated with IBS. Further investigation is needed to elucidate the shared pathogenesis underlying these two diseases.

Urticaria is a prevalent disease with substantial physical, psychological, and economic impacts. With the advent of understandings of the disease and the emerging evidence of treatments, the international guidelines for treating urticaria have been updated in recent years. In order to update the 2014 edition of the Taiwanese Dermatological Association (TDA) consensus of urticaria, a total of 17 dermatologists with extensive experience in urticaria management were invited to and attended the TDA consensus meetings. All the specific aspects of the content were approved by at least 75% of the experts in attendance. Comparing to the former edition, several substantial modifications were made. For diagnosis, D-dimer was added as the recommended routine test in patients with chronic spontaneous urticaria. For pharmacological management, treatment suggestions were simplified. The approved-dosed, the up-dosed second-generation antihistamines, omalizumab, and cyclosporine were listed as the first-line to the fourth-line treatment, respectively. In addition, the management for patients of special considerations, such as the elderly, children, and pregnant women, were all discussed and mentioned in the consensus. We hope the updated TDA consensus can serve as a reference for all physicians and can help the physicians providing up-to-dated managements for these patients.

BACKGROUND: The preliminary results of an innovative surgical technique, which incorporated single-port three-dimensional (3D) videoscope and instruments for endoscopic nipple-sparing mastectomy (E-NSM), were reported. METHODS: The medical records of patients who underwent single-port 3D E-NSM for breast cancer from August 2018 to September 2020 were analyzed, and the preliminary outcome of this procedure as well as the patient-reported aesthetic results are described in this article. RESULTS: The study enrolled 70 patients who received 80 procedures of single-port 3D E-NSM. The mean operation time was 158 ± 36 min, and the mean blood loss was 41 ± 26 ml. Three procedures (3.8 %) associated with delayed axillary wound-healing, eight cases of transient nipple ischemia (10 %), three cases of partial nipple ischemia/necrosis (3.7 %), and one case of total nipple-areolar complex (NAC) necrosis (1.3 %) were observed. No patient had margin involvement. Satisfaction rates of approximately 90 % were observed in terms of postoperative scar appearance, location, and length. Most of the patients (87.8 %) reported that they would choose the same operation again if given the chance to do so. The overall cost of a single-port 3D E-NSM was 7522 ± 470 U.S. dollars. According to cumulative sum (CUSUM) plot analysis, about 14 cases were needed for surgeons to familiarize themselves with single-port 3D E-NSM and immediate gel implant reconstruction and to decrease their operation time significantly in the initial learning phase. CONCLUSION: Single-port 3D E-NSM, a safe, efficient, lower-cost procedure, is associated with a good aesthetic result. It is a promising new technique for breast cancer patients indicated for mastectomy, but long-term oncologic safety follow-up evaluation still is needed.

OBJECTIVE: Posttraumatic stress disorder (PTSD) is known as a risk factor for various immune-related disorders; however, the association between PTSD and related autoimmune skin diseases (ASDs) remains unclear. This study aimed to investigate the association of PTSD with the risk of related ASDs. METHODS: Participants were recruited from the National Health Insurance Research Database in Taiwan. We included 9801 patients with PTSD and 39,204 matched controls to assess the risk of developing ASDs. Cox regression model was used for analyses. RESULTS: After adjusting for confounders, we found an increased risk of ASDs among the patients with PTSD (adjusted hazard ratio [aHR] = 3.00, 95% confidence interval [CI] = 2.21-4.07) compared with that among matched controls. Statistically significant associations were found between PTSD and five individual ASDs, including psoriasis (aHR = 3.81, 95% CI = 1.90-7.67), lichen planus (aHR = 31.63, 95% CI = 4.00-249.91), alopecia areata (aHR = 4.77, 95% CI = 2.47-9.20), autoimmune bullous diseases (aHR = 9.55, 95% CI = 1.98-45.99), and vitiligo (aHR = 16.06, 95% CI = 4.48-57.54). CONCLUSIONS: Patients with PTSD had an increased risk of developing ASDs compared with the matched controls. Further studies are needed for better understanding of the underlying mechanisms.
