... Psoriasis-associated altered circulating lipid levels 45 and abnormal lipid composition in plaque and nonlesional skin 3 have been linked with decreased fatty acid elongation and disruption of the skin barrier function. [46][47][48][49] For instance, ELOVL3, FADS1 and FADS2, which encode enzymes that participate in the elongation of long-chain fatty acids are downregulated in plaque and non-lesional skin compared to healthy skin. 34,[50][51][52][53][54] The upregulation of genes such as ELOVL3 and PECR in non-lesional skin and ELOVL3 and FADS2 in plaque skin may improve lipid barrier function, suggesting that bevacizumab could potentially alleviate epidermal barrier dysfunction and limit disease progression in psoriasis. ...

... Ultimately, conclusions are derived from consumer self-reports gathered through a questionnaire. Comparison of data gathered in China, Korea, and the US indicate no significant difference in skin type prevalence between Asian and Caucasian populations [5], which supports the BSTI as a valuable and comprehensive tool for determining skin types [6][7][8]. ...

... A patient waiting for treatment described their experience by saying, "We await the medical missionary workers like children waiting for their parents. " From 1925 to 1929, Sa Young Ahn 3 and Eun-gye Lee (two doctors trained in Severance Hos-pital) worked as doctors in the Swedish Methodist Hospital. In particular, Ahn served the community faithfully through many different roles, including medical service to teaching as well as missionary and administrative work (Singanhoe). ...

... The Swedish Methodist Hospital (Fig. 2) re-opened in February 1925, thanks to the proactive efforts of a medical missionary worker named Anderson. 2 The closure of the hospital turned out to be a blessing in disguise, as the people of the area began to appreciate the hospital more in its absence. For a short period after its re-opening, the hospital only offered out-patient treatments due to the time required to train assistants and nurses required to operate the hospital. ...

... There are only three reports of porokeratosis ptychotropica in the Korean literature [11][12][13], and 45 cases have been reported in the dermatologic literature. Therefore, in this case report, we attempted to highlight the awareness of this condition and emphasize that clinicians should consider porokeratosis ptychotropica in their differential diagnosis when encountering pruritic eruptions in the gluteal regions. ...

... These results tell us that the prevalence of psoriasis is low in sub-Saharan Africa and lower than that of Western countries. Indeed, in a systematic review, Parisi et al. demonstrated that psoriasis is unevenly distributed across geographic regions and is more common in high-income countries and regions with older populations [11]. The study population was dominated by men with a sex ratio of [14] in their study in Maghreb found a female predominance with a sex ratio of 0.6. ...

... Other abnormalities can include horseshoe kidneys, hernias, hearing defects, intellectual disability and congenital heart disease [11,14]. From published research relating to FDH, there are only nine cases of unilateral/almost unilateral FDH, out of approximately 250 cases [15][16][17][18][19][20][21][22]. This report demonstrates a rare case of FDH presenting with unilateral symptoms and will subsequently only be the 10th unilateral FDH published in the literature and only the second male case. ...

... Hypersensitivity reactions to injected agents, such as hyaluronan, can cause symptoms similar to those of septic arthritis, including joint pain and swelling [58]. Additionally, bone conditions like Gorham disease, SAPHO syndrome, chronic recurrent multifocal osteomyelitis, Paget disease, systemic mastocytosis, and synovial chondromatosis can present with atypical and challenging clinical manifestations [30]. ...
