RESUMEN
BACKGROUND: Demodex density is known to increase in various immunosuppressive conditions. The relationship between biologic therapy and Demodex density remains unknown. We aimed to investigate whether the density of Demodex mites is higher in psoriasis patients treated with biologic agents compared to treatment-naive or topically treated patients. METHODS: A cross-sectional study was conducted, comparing psoriasis patients receiving biologic therapy (n = 34) with controls (n = 33). Demodex density was assessed using the standardized skin surface biopsy technique (SSSB). Statistical analysis was performed to compare the densities and prevalence of demodicosis between the two groups. RESULTS: Demodex density was significantly higher in the biologic therapy group compared to the control group on the right cheek (7.29 vs. 0.12/cm2; P = 0.001), left cheek (8.15 vs. 0.24/cm2; P = 0.002), and whole face (average of all four regions: 5.50 vs. 0.80/cm2; P = 0.001). The prevalence of demodicosis was significantly higher in the biologic therapy group on the forehead (35.3% vs. 12.1%; P = 0.043), right cheek (41.2% vs. 0%; P < 0.001), and left cheek (44.1% vs. 0%; P < 0.001). The frequency of cases with demodicosis in at least one localization was higher in the biological therapy group compared to the control group (61.8% vs. 15.2%; P < 0.001). CONCLUSIONS: Psoriasis patients receiving biologic therapy had a higher Demodex density and prevalence of demodicosis compared to controls. Biologics may lead to an increase in Demodex density by blocking specific cytokines, such as interleukin-17 and tumor necrosis factor-α, which play a role in immunity against Demodex. Further research is needed to explore the impact of different biological agents on Demodex density.
RESUMEN
BACKGROUND: Human Demodex mites, Demodex folliculorum and Demodex brevis, are microorganisms that reside in the pilosebaceous units, usually without causing symptoms. Phototherapy has been linked to demodicosis in previous studies. We aimed to determine whether there was an increase in the frequency of demodicosis and Demodex density after 20 phototherapy sessions. METHODS: A case-control study was conducted with 32 participants who received narrowband ultraviolet B or ultraviolet A-1 therapy for various dermatological indications. Standardized skin surface biopsies were performed before and after phototherapy to assess Demodex density. The presence of Demodex-related skin conditions was assessed before phototherapy. A statistical analysis was performed to compare the Demodex densities and prevalence of demodicosis between the baseline and 20th session of phototherapy. RESULTS: No significant change was observed in Demodex density after 20 sessions of phototherapy. The average Demodex density before treatment was 2.75 ± 4.48 (/cm2 ), and after treatment, it was 2.85 ± 4.81 (/cm2 ), indicating no significant difference (P = 0.879). The percentage of patients with demodicosis in at least one region of the face was 28.1% (9/32) before treatment, and after treatment, it was 31.3% (10/32), with no significant difference (P = 1.00). CONCLUSIONS: Our findings contradict previous studies that suggested an increased Demodex density and demodicosis prevalence after phototherapy. The data from previous studies are open to debate due to their selected samples, designs, and interpretations regarding the phototherapy-immunosuppression-Demodex relationship. Larger-scale longitudinal studies conducted on a homogeneous sample are warranted to better understand the relationship between phototherapy and demodicosis.

The analysis of landslide susceptibility is a crucial tool in the mitigation and management of ecological and economic hazards. The number of studies examining how the form and durability of forest areas affect landslide susceptibility is very limited. This study was conducted in the Marmara region of northwestern Türkiye, where forested areas and industrial zones are intertwined and dense. The landslide susceptibility map was produced by Analytic Hierarchy Process (AHP) method. In the context of AHP, a total of 12 different variables were employed, namely lithology, slope, curvatures, precipitations, aspect, distance to fault lines, distance to streams, distance to roads, land use, soil, elevation, and Normalized Difference Vegetation Index (NDVI). The performance analysis of the landslide susceptibility map was conducted using the Receiver Operating Characteristics (ROC) curve method. The AUC value was computed (0.809) for the landslide susceptibility map generated by using the AHP technique. Forest type maps were used to analyze the impact of forests on landslide susceptibility. In terms of forest structure, 4 main criteria were determined: stand structure, development stage, crown closure, and stand age. Each criterion was analyzed with Geographic Information Systems (GIS) by overlaying it with the landslide susceptibility map of the study area. The results showed that the risk of landslides was lowest in forests with more than one tree species, mature, development stage and of (e) > 52 cm, and crown closure of 41%-70% (2).

Today, data mining has become a relevant topic in digital soil mapping. In this current study, prediction of some soil properties and their spatial distribution were examined by machine learning algorithms (Support Vector Machine, Artificial Neural Network) using reflectance values of Triplesat satellite image bands in Vezirköprü district of Samsun province. The band data obtained from different wavelengths revealed positive correlations between the electrical conductivity and calcium carbonate equivalent contents of the soils. The support vector machine algorithm was the most successful to estimate the textural fractions, organic matter, electrical conductivity, and calcium carbonate equivalent contents of the soils using the bands obtained from satellite images. The mean absolute error for estimating sand, silt, and clay contents by support vector machine was 4.05%, 3.05%, and 3.66%, respectively. Texture classes were determined with an accuracy of 82% with support vector machine and 60% with artificial neural network. In all estimations, the highest percentage of error was for calcium carbonate equivalent content with very low estimation reliability. The mean absolute percentage of error values for this property are 101.13% and 51.61% for artificial neural network and support vector machine, respectively. Also, in both algorithms, the most successfully estimated soil property was clay fraction of soils. It was also investigated the spatial distribution of actual and estimated values using various interpolation methods (Kriging, inverse distance weighting-, radial basis function). Considering the spatial distributions, it was determined that the most successful method was kriging for sand, silt, and clay contents and inverse distance weighting for electrical conductivity, calcium carbonate equivalent, and organic matter contents. According to our findings, it is concluded that successful estimations and spatial distributions can be made by the support vector machine algorithm using band data from different wavelengths.

INTRODUCTION: Glove-induced dermatoses are frequently seen among healthcare workers (HCWs) and are often mistakenly defined as latex allergy. OBJECTIVES: To determine the prevalences of (i) the symptoms of immediate type hypersensitivity reactions, (ii) the symptoms of hand eczema, (iii) latex sensitization detected using skin prick test (SPT), and (iv) contact hypersensitivity to rubber additives or glove pieces detected using patch test, in Turkish HCWs. METHODS: Ninety-eight HCWs were included in the study. All subjects completed a questionnaire. All participants were skin prick tested for latex, and foods previously identified as concomitant allergens in latex-sensitive individuals; patch tested for 7 rubber additives, 3 additional haptens, and glove pieces. RESULTS: The mean age was 32.1 (± 9.4) years, and 71 (72.4%) participants were nurses. Eighty-four (85.7%) subjects had a history of mucocutaneous symptoms of immediate-type hypersensitivity occurring within the first 24 hours after latex glove contact, while 9 (9.2%) subjects demonstrated SPT positivity for latex. Eighty (81.6%) subjects had a history of glove-induced hand eczema symptoms, while patch test positivity for the rubber additives or glove pieces was in 17.3%. CONCLUSIONS: About one-tenth of those with a history of glove-induced type I hypersensitivity symptoms had true latex allergy, and one-quarter of those with a history of glove-related hand eczema symptoms had contact hypersensitivity to glove products. Therefore, rote avoidance of latex use is generally ineffective in the management of glove-related skin complaints. Individual measures should focus on reducing the use of soaps and disinfectants, and promoting the use of moisturizers, rather than glove choice.
RESUMEN
INTRODUCTION: Acne occurring in adults over the age of 25 years is known as acne tarda or adult acne. Three types of adult acne are recognized: persistent, late-onset, and recurrent acne. Most studies do not compare the characteristics between the three variants. In addition, little is known about adult acne in males. This study describes the epidemiological factors of adult acne and investigates certain triggering factors by sex and different types of adult acne. METHODS: A multicenter, prospective, descriptive study was conducted. Patients with adult acne and an acne-free control group were compared regarding medical history, family history, smoking and drinking habits, and dietary factors. In addition, triggering and prognostic factors were investigated by sex and three different types of acne: persistent, late-onset, and recurrent acne. RESULTS: The participants included 944 (88.56%) female and 122 (11.44%) male patients with adult acne, and 709 (73.85%) female and 251 (26.15%) male control patients. The consumption of crackers, chocolate, and pasta was significantly more common in the acne group than in the control group (p = 0.017, 0.002, and 0.040, respectively). Male patients with adult acne had a significantly longer disease duration than female patients with adult acne (p = 0.024). The most common type of acne was recurrent acne, followed by persistent and late-onset acne. Among patients with persistent acne, 14.5% had polycystic ovary syndrome (PCOS), whereas 12.2% of patients with recurrent acne and 11.1% of patients with late-onset acne had PCOS. Severe acne was more common in the persistent acne type (28.13%). The cheek (59.90%) was the most common involvement area, and stress (55.23%) was the most common triggering factor regardless of sex. CONCLUSIONS: Although adult female and male patents with adult acne share similar triggering factors, the involvement areas can differ, which may indicate the additional hormonal etiology of female adult acne. Further epidemiological studies on adult acne in both sexes may illuminate the pathogenesis of the disease, thus making possible the development of new treatment strategies.

Background: Acne vulgaris (AV) is among the common skin diseases for which patients refer to complementary and alternative medicine (CAM). Aims and Objectives: To investigate the approaches to CAM methods and factors believed to increase the disease in 1,571 AV patients. Materials and Methods: The sociodemographic characteristics of the patients and disease severity according to the Food and Drug Administration criteria were recorded. The Cardiff Acne Disability Index (CADI) was used to assess the impact of acne on the patient's life and the history of CAM use was noted. The patients also listed the factors that they thought worsened their disease and reported their gluten-free diet experiences. Results: Of all the patients, 74.41% had a history of using CAM methods. CAM use was significantly higher in women, patients with severe AV, those with a higher CADI score and non-smokers. As a CAM method, 66.37% of the patients reported having used lemon juice. The respondents most frequently applied CAM methods before consulting a physician (43.94%), for a duration of 0-2 weeks (38.97%). They learned about CAM methods on the internet (56.24%) and considered CAM methods to be natural (41.86%). The patients thought that food (78.55%) and stress (17.06%) worsened their disease. They considered that the most common type of food that exacerbated their symptoms was junk food (63.84%) and a gluten-free diet did not provide any benefit in relieving AV (50%). Conclusion: Physicians need to ask patients about their CAM use in order to be able to guide them appropriately concerning treatments and applications with a high level of evidence.
RESUMEN
There are safety concerns in the treatment of pemphigus patients with immunosuppressants, particularly rituximab (RTX), in times of the COVID-19 pandemic. In the beginning, the reports were more pessimistic. However, few reports have recently pointed to manageable courses in this patient group. Therefore, we investigated the disease characteristics and demographic features of pemphigus patients in the period of the COVID-19 pandemic. We aimed to investigate the impact of immunosuppressants on the course of COVID-19 in pemphigus patients. Also, we tried to find out the rate of flares due to COVID-19 and SARS-Cov-2 vaccines. This multicenter study included 247 patients with pemphigus from three tertiary dermatology clinics with the specialized outpatient clinic for autoimmune blistering diseases. Patients were asked standardized questions in person or via telephone calls. Also, demographic data were collected from patients' files. Two hundred forty-four of 247 patients took the survey between August and September 2021. The data of three patients were obtained from the National Health System. We collected the data of all pemphigus patients who visited the clinics at least once in the past 3 years. Among 51 patients having COVID-19, 40 had a non-serious disease, whereas 11 required hospitalization. One patient died because of COVID-19 infection. The number of patients is limited, and data depends mainly on patients' statements. RTX treatment does not require additional safety cautions than other immunosuppressives.

BACKGROUND: Skincare products and cosmetic procedures are used as an adjunct or complementary to conventional drug therapy for acne vulgaris (AV). OBJECTIVE: To evaluate the use of skincare products and the frequency of cosmetic procedures in AV treatment. METHODS: A total of 1,755 patients with AV completed the survey prepared by the researchers and the Cardiff Acne Disability Index (CADI) questionnaire. The clinical findings and the Food and Drug Administration (FDA) severity scores were recorded by the dermatologists. RESULTS: For AV, 66.7% of the patients stated that they used skincare products and 26.7% had undergone cosmetic procedures. The use of skincare products was statistically significantly higher in women (female: 74.5%, male: 57.7%, p < 0.0001); older people (users: 22 ± 7.6years, non-users: 21.2 ± 5.7 years, p < 0.0001); patients with a higher CADI score (users: 7 ± 3.7, non-users: 6.9 ± 4.3, p = 0.010); FDA severity score 2 and 3 (FDA-1: 58.1%; FDA-2: 72.4%, FDA-3: 73%, FDA-4: 67%, p < 0.0001); long-term disease (users: 57 ± 43 months; non-users: 47.7 ± 42.3 months, p < 0.0001); facial involvement (present: 70.2%, absent: 51.4%, p = 0.017); high income levels (users: 73.5%; non-users: 26.5%, p = 0.001); and graduate or post-graduate degrees (undergraduate≤%62.8, graduate≥%76.8, p < 0.0001). The rate of cosmetic procedures was higher in those with higher CADI scores (users: 7.8 ± 3.8; non-users: 7.1 ± 3.96, p < 0.0001); older patients (users: 22.7 ± 10.7 years; non-users: 21.3 ± 5 years, p < 0.0001); high school (25.6%); and graduate (28.9%) education (p = 0.043), those with lower disease severity (FDA-1: 31.1%; FDA-2: 28.5%, FDA-3: 27.1%, FDA-4: 20.4%, p = 0.022); smokers (smokers: 32.5%; non-smokers: 25.5%, p = 0.020), and those with AV in the family (present: 29.8%; absent: 24.2%, p = 0.009). The patients most frequently used cleansers (85.2%) as cosmetic products, and most commonly underwent skincare treatment (71%) as an interventional procedure. They mostly learned about such products and methods from the Internet, and 33.3% of the participants had undergone procedures performed by non-physicians. CONCLUSION: The patients generally choose skincare products as a result of their Internet search and sometimes have these procedures performed by non-physicians. Dermatologists should be aware of this situation and inform their patients about appropriate products and procedures.

COVID-19 is a febrile, infectious illness that has previously been associated with telogen effluvium (TE). However, to date, no study has been conducted to determine the incidence of TE in those who have had COVID-19. To assess the frequency of TE in post-COVID-19 patients and the correlation between the development of TE and the severity of COVID-19, to understand whether emotional stress or medications are responsible for the development of TE. Totally 204 patients with a history of SARS-CoV-2 infection in the last 3 months were included in the study. The diagnosis of TE was made by history of excessive hair shedding, hair pull test, diffuse or bitemporal thinning, and absence of anisotrichosis in trichoscopy. Patients who did not have any TE cause other than COVID-19 and whose hair loss started after COVID-19 were considered as "COVID-19 associated TE (CATE)." We found TE in 75 (36.7%) cases and androgenetic alopecia (AGA) in 85 (41.7%) cases. CATE was present in 27.9% of cases and developed on average 53.76 (± 23.772) days after COVID-19 real-time reverse transcription polymerase chain reaction (RT-PCR) positivity. The proportion of patients with CATE was numerically higher in hospitalized patients compared to outpatients (31.7% vs. 24.3%; p = 0.238); and significantly higher in women compared to men (42.3% vs. 6.2%; p < 0.001), in patients with hypertension compared to those without hypertension (40.4% vs. 23.1%; p = 0.014), and in patients who had respiratory symptoms compared to those who had not (31.7% vs. 14.0%; p = 0.021). The patients with and without CATE were similar in terms of stress level and usage of COVID-19 medications. Patients with AGA had a higher rate of hospitalization (69.4% vs. 35.3%; p < 0.001) and a higher incidence of fever (69.4% vs. 54.6%; p = 0.033) during COVID-19, compared to those without. TE developed in approximately one-quarter of people who have had COVID-19, and our study is the first to detect it. The time to onset of CATE, which was 7-8 weeks after the SARS-CoV-2 RT-PCR positivity, was not much different from post-infectious TE. Patients with severe COVID-19 seem to be more prone to develop TE. The presence of AGA is associated with a more severe COVID-19. During the pandemic, clinicians should consider a previous SARS-CoV-2 infection in patients presenting with hair loss.

We aimed to investigate the effects of Calendula officinalis and Echinacea purpurea extracts in terms of growth parameters, antibacterial activity and phenolic profile in tomato infected by Clavibacter michiganensis subsp. michiganensis (CmmT7). A significant difference was observed in E. purpuraextract, indicating the highest effects on plant height (27.25 cm), fresh plant weight (28.45 cm), root length (24.42 cm), and root weight (6.74 g) (p<0.05). Moreover, Calendula officinalis and Echinacea purpurea extracts showed significant inhibitory activity against CmmT7 (p<0.05). Among phenolic compounds, the only chlorogenic acid amounts were varied in the tomato seedlings leaves with C. officinalis extract (K3) + CmmT7, E. purpurea extract (E3) + CmmT7 and CmmT7 (p<0.01). Moreover, chlorogenic acid amount was approximately 9 times higher than in CmmT7-treated leaves when compared to control. The results showed that application of the extracts of these plants had a significant influence on bacterial canker and growth parameters.
Nuestro objetivo fue investigar los efectos de los extractos de Calendula officinalis y Echinacea purpurea en términos de parámetros de crecimiento, actividad antibacteriana y perfil fenólico en tomate infectado por Clavibacter michiganensis subsp. michiganensis (CmmT7). Se observó una diferencia significativa en el extracto de E. purpura, que indica los mayores efectos sobre la altura de la planta (27,25 cm), el peso de la planta fresca(28,45 cm), la longitud de la raíz (24,42 cm) y el peso de la raíz (6,74 g) (p<0,05). Además, los extractos de Calendula officinalis y Echinacea purpurea mostraron una actividad inhibidora significativa contra CmmT7 (p<0,05). Entre los compuestos fenólicos, las únicas cantidades de ácido clorogénico se variaron en las hojas de las plántulas de tomate con extracto de C. officinalis (K3) CmmT7, extracto de E. purpurea(E3) CmmT7 y CmmT7 (p<0.01). Además, la cantidad de ácido clorogénico fue aproximadamente 9 veces mayor que en las hojas tratadas con CmmT7 en comparación con el control. Los resultados mostraron que la aplicación de los extractos de estas plantas tuvo una influencia significativa sobre el cancro bacteriano y los parámetros de crecimiento.

BACKGROUND: The rate of cosmetic procedures and use of skincare products is considered to be affected during the pandemic period; however, this has not been investigated yet. OBJECTIVE: To determine whether the ongoing pandemic has changed people's habits related to skincare products and cosmetic procedures. METHODS: We conducted a multicenter survey study covering both private and public hospitals. Sociodemographic characteristics and clinical diagnoses of the patients were noted by dermatologists. A survey was used to determine the type and application areas of skincare products and cosmetic procedures before and during the pandemic, whether the patients were concerned about being infected, and any change in the make-up habits of female patients. RESULTS: Of the 1437 patients, 86.7% presented to the hospital due to dermatological complaints and 13.3% for cosmetic procedures. The rate of those that did not use skincare products was 0.05% before and 0.06% during the pandemic. Of the participants, 43.2% had undergone cosmetic procedures before and 38.1% during the pandemic. For both periods, the most frequent cosmetic procedure applied was laser epilation, followed by skincare treatment and chemical peeling. While undergoing these procedures, 34.9% of the patients were concerned about contracting coronavirus. CONCLUSION: There was no significant difference in the use of skincare products and cosmetic procedures before and during the pandemic. The majority of the patients continued to undergo these procedures despite their fear of being infected. This shows that during the pandemic period, patients are concerned with their appearance and continue to undergo cosmetic procedures and pay attention to their skincare.

The purpose of this study, covering the northern Ulus district of Turkey, was to analyze the forest and land use/land cover (LULC) changes in the past period from 2000 to 2020, and to predict the possible changes in 2030 and 2040, using remote sensing (RS) and geographic information systems (GIS) together with the CA-Markov model. The maximum likelihood classified (MLC) technique was used to produce LULC maps, using 2000 and 2010 Landsat (ETM +) and 2020 Landsat (OLI) images based on existing stand-type maps as reference. Using the historical data from the generated LULC maps, the LULC changes for 2030-2040 were predicted via the CA-Markov hybrid model. The reliability of the model was verified by overlapping the 2020 LULC map with the 2020 LULC model (predicted) map. The overall accuracy was found to be 80.90%, with a Kappa coefficient of 0.74. The total forest area (coniferous + broad-leaved + mixed forest) grew by 10,656.4 ha (15.4%) in the 2000-2020 period. Examination of the types within the Forest Class revealed that the coniferous forest area had grown by 5.9% in the period 2000-2010, whereas it had decreased by 4.7% in the period 2010-2020. The broad-leaved forest area had grown by 1.2% and 3.1%, respectively, between 2000 and 2010 and 2010 and 2020. The mixed forest area had been reduced by 7.1% in the period 2000-2010 but had grown by 1.7% in the 2010-2020 period. In the Non-Forest Class, although the water area had increased in the 2000-2020 period, agricultural land and settlement areas had decreased by 11,553.9 ha (32.3%) and 34.6 ha (0.5%), respectively. According to the 2020-2040 LULC simulation results, it was predicted that there would be 3.8% and 26.4% growth in the total forest and water surface areas and 13.9% and 5.3% reduction in the agricultural and settlement areas, respectively. Using the LULC simulation to separate the Forest Class into coniferous, broad-leaved, and mixed forest categories and subsequently examining the individual changes can be of great help to forest planners and managers in decision-making and strategy development.

BACKGROUND: Acne vulgaris (AV) may affect external appearance and significantly deteriorate the quality of life of patients. Therefore, patients make various inquiries about their disease and seek treatment options. AIMS: To investigate the social media usage habits of patients with AV concerning their diseases, and their recommendations for dermatologists related to social media use. METHODS: A total of 1609 patients with AV completed the survey prepared by the authors and the Cardiff Acne Disability Index questionnaire. The Food and Drug Administration severity scores and clinical information of the patients were noted by their physicians. RESULTS: Of the 1,489 patients who stated that they used social media, 46.31% regularly and 28.77% sometimes referred to these sources to make inquiries about AV. Social media usage for AV was statistically significantly higher in women, participants with short term and severe disease, those with a moderate income level, and those using topical treatment and cosmetics. They mostly used Google (67%), Instagram (54%), and YouTube (49%). While 76% of the participants stated that they did not share what they saw on the Internet with their doctor. Of the respondents, 18.5% were trying to contact their dermatologists through the Internet, and 69.73% would prefer experts such as dermatologists to post-AV-related content. CONCLUSIONS: Our study shows that patients frequently resort to social media to seek information about AV. In the changing digital world order, it is observed that there is a need for dermatologists to use social media more actively to share accurate information about AV.

OBJECTIVE: This study aims to determine the validity and reliability of the Turkish translation of brief diabetic foot ulceration risk checklist (BDURC). METHODS: This methodological study was conducted at the diabetes clinic of a state hospital in Istanbul, Turkey. The data were collected with the BDURC developed by Zhou et al. in 2018. A study was conducted with 430 patients with Type 2 diabetes. The scale was retested after 4 weeks by 60 participants. Language equivalence of the scale was provided. Experts' opinions were taken about the content validity of the scale. Reliability of the scale was determined with the test-retest reliability, item-total correlation, and internal consistency analysis. RESULTS: Confirmatory factor analysis revealed a two-factor structure with good model suitability. Cronbach's alpha coefficient for the scale and its subscales was 0.79. Test-retest scores showed no statistically significant difference between the items (p>0.05). The reliability index was higher than 0.80. CONCLUSION: The BDURC-TR is a valid and reliable tool that can be used in clinics to identify the risk factors for diabetic foot ulcers in patients with Type 2 diabetes in Turkey.
RESUMEN
Depression is a comorbidity of psoriasis. Suppression of neurotrophins has been proposed to cause depression. Peripheral brain-derived neurotrophic factor (BDNF) and its precursor, pro-BDNF have been shown to be altered in depression. To compare serum pro-BDNF and BDNF levels, depression, anxiety, and quality of life (QoL) in psoriasis patients, diseased, and healthy controls, to assess impact of 12-week antipsoriatic treatment on abovementioned markers. At baseline, all groups completed Beck Depression Inventory (BDI), Spielberger State-Trait Anxiety Inventory-II (STAI-II) and DLQI; serum BDNF, proBDNF levels were measured. These were repeated after 3-months of treatment in psoriasis patients. Depression and anxiety were significantly higher, QoL was poorer in psoriasis. ProBDNF and proBDNF/BDNF ratios were not different among groups at baseline but significantly decreased after treatment in psoriasis. Depression and QoL improved significantly, BDNF and anxiety scores did not change. Altered pro-BDNF and proBDNF/BDNF ratios may have a role in depression pathogenesis in psoriasis. Antipsoriatic treatment causes improvement in depression, QoL, and reduction of proBDNF and proBDNF/BDNF ratios. Effective disease control may reverse dysregulated neurotrophin pathways and its consequences like depression.

Lipedema is a painful, underdiagnosed adipose tissue disorder, characterized by symmetrical swelling of the extremities due to subcutaneous fat deposition in the buttocks, thighs, legs, and arms, sparing the most distal part of the extremities. Although etiology and pathogenesis of lipedema is unclear, possible role of hormonal and genetic factors have been proposed previously. Patients with lipedema suffer from pain, easy bruising, tenderness, and disfigurement. Pain is the leading symptom in lipedema. Since the pain is associated with depression and impaired quality of life, reduction of pain is the major therapeutic approach. Pain in lipedema is attributed to allodynia, exaggerated sympathetic signaling, and estrogens. Although the mechanism of pain in lipedema is uncertain, effective treatment of lipedema should provide a satisfactory pain reduction. Efficacy of the conservative treatment is a matter of debate. Microcannular tumescent liposuction is the most effective therapeutic option for lipedema. There is a large body of evidence that this procedure significantly reduces pain in patients with lipedema.
