    Behçet's disease (BD) is a multisystemic, relapsing inflammatory disorder with an obscure etiology and pathogenesis. Diagnosis depends on the clinician's ability to identify a group of nonspecific mucocutaneous lesions, which also manifest in a number of other diseases. In recent years, there has been an increase in the studies focusing on the histopathological aspects of Behçet's disease diagnostic mucocutaneous lesions. Their results emphasize the value of histopathology and direct immunofluorescence (DIF) in the differential diagnosis of Behçet's disease

    Background and Design: This study aimed to investigate the effects of the precautions and preventive measures implemented during the coronavirus disease-2019 (COVID-19) pandemic on the follow-up and treatment processes of patients with rosacea who applied to the Skin and Venereal Diseases outpatient clinic of a university hospital in Türkiye. Materials and Methods: Age, sex, number of hospital admissions, prescribed topical and systemic treatments, total amount of treatment on a box basis, follow-up interval in multiple applications, and number of applications to the Ophthalmology Department were recorded before and during the COVID-19 pandemic. Results: No difference was found in the age and sex distributions of patients with rosacea who applied to the Skin and Venereal Diseases outpatient clinic during the COVID-19 pandemic compared with that before the pandemic. However, the total number of patients decreased. Furthermore, the total number of drugs prescribed to patients and the number of systemic drugs increased proportionally during the COVID-19 pandemic. In addition, the ratio of patients who continued their follow-up and the use of systemic drugs among these patients increased. Conclusion: In this study, the number of admissions decreased and the rate of patients who needed systemic treatment increased. Rosacea and similar dermatoses that required long-term follow-up could be evaluated via teledermatology during periods when application to outpatient clinics for follow-up becomes difficult such as during pandemics and natural disasters

    Introduction:Telogen effluvium (TE) is a common form of non-scarring alopecia that may manifest as acute or chronic hair shedding. Several studies evaluated a possible relationship between various vitamin and mineral deficiencies and TE, but it is still a controversial topic. Objectives: This study aimed to investigate the status of vitamin and mineral deficiencies in patients diagnosed with TE and to evaluate their correlation with anagen hair ratios (AHR) calculated with an automated digital phototrichogram (ADCP). Methods:Electronic records of 973 TE patients were retrospectively analyzed. Demographic, clinical data, parameters such as ferritin, vitamin B12 (Vit-B12), vitamin D (Vit-D), folic acid, zinc and hemoglobin (HGB) serum levels were evaluated. Anagen to telogen hair ratios were also assessed in forty-two patients via ADCP. Results: The rates of anemia, low ferritin level, and Vit-B12, folate, Vit-D, and zinc deficiencies were 11.9% (N = 109), 44% (N = 332), 1.5% (N = 13), 2.5% (N = 14), 87% (N = 51), and 4.5% (N = 2), respectively. A positive correlation was found between HGB levels and AHR in female patients (Spearman rank, r = 0.417, P = 0.008). No statistically significant relationship was found between ferritin, Vit-B12, folate, zinc serum levels and AHR. The relationship between Vit-D and AHR could not be assessed due to the insufficient number of patients with Vit-D data. Conclusions:HGB value is the only marker that is positively correlated with the AHR of patients with TE. Ordering HGB can be used as an initial test for managing TE patients cost-effectively.

    Non-steroidal anti-inflammatory drugs produce antinociceptive effects mainly through peripheral cyclooxygenase inhibition. In opposition to the classical non-steroidal anti-inflammatory drugs, paracetamol and dipyrone exert weak anti-inflammatory activity, their antinociceptive effects appearing to be mostly due to mechanisms other than peripheral cyclooxygenase inhibition. In this review, we classify classical non-steroidal anti-inflammatory drugs, paracetamol and dipyrone as “non-opioid analgesics” and discuss the mechanisms mediating participation of the endocannabinoid system in their antinociceptive effects. Non-opioid analgesics and their metabolites may activate cannabinoid receptors, as well as elevate endocannabinoid levels through different mechanisms: reduction of endocannabinoid degradation via fatty acid amide hydrolase and/or cyclooxygenase-2 inhibition, mobilization of arachidonic acid for the biosynthesis of endocannabinoids due to cyclooxygenase inhibition, inhibition of endocannabinoid cellular uptake directly or through the inhibition of nitric oxide synthase production, and induction of endocannabinoid release

    Content storage at the network edge is a promising solution to mitigate the excessive traffic load due to on-demand streaming applications as well as to reduce the streaming delay. To this end, cache-enabled cellular architectures can be utilized to increase the provided quality-of-service (QoS) and to reduce the network cost. However, there are certain issues to be considered in the design of the content storage strategy such that the contents should be refreshed in order to responds user`s expectations. Using a frequent cache refreshment strategy the ratio of satisfied users can be increased at an increasing network cost. In this paper, we introduce a cache refreshment strategy via leveraging learning techniques so that users' tolerance to the age of content is learned and the content is refreshed accordingly

    Objective: To determine the effects of yttrium-90 (Y-90) resin microsphere radioembolization therapy on patients with unresectable liver cancer who do not benefit from chemotherapy. Methods: Fifty-five patients underwent radioembolization therapy included in the study whose had unresectable primary or metastatic liver cancer originating from the gastrointestinal tract. Three were excluded from the study after pre-evaluation angiography. Thirteen (23.6%) of the remaining 52 patients had hepatocellular carcinoma and 39 (76.4%) had metastatic liver cancer. Fifty-two patients underwent Y-90 radioembolization treatment. Each patient's response to the administered treatment was evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) and the overall probability of survival was displayed graphically by the Kaplan-Meier method. Results: After Y-90 therapy, 47 patients were follow-up. While 57% of the patients responded to treatment as clinical benefit, the disease progressed in 43%. The median hepatic progression-free survival time of the patients was 3.4 months (95% confidence interval (ci):1.4-5.3) and the overall survival time was 11.3 months (95%, CI:8.7-14.03). Conclusion: This study emphasizes that Y-90 resin microsphere radioembolization treatment is effective in patients with unresectable liver cancer
