“Doll #135 with vitiligo”: Are alopecia and vitiligo Barbie worth the hype?

Toy manufacturer Mattel released a new line of diverse Barbie dolls earlier this year, including dolls with alopecia and vitiligo. The new dolls have been widely celebrated, with both media and dermatologists proposing that the dolls could provide significant benefits for the low self-esteem and societal exclusion suffered by children with similar dermatoses. However, the reality may be very different. Here, we present existing research on the impact of diverse dolls on children’s play and psychology to argue that the dolls’ proposed benefits for children with alopecia and vitiligo are unlikely to materialize; rather, alopecia and vitiligo Barbie could prove more harmful than beneficial.     

Biosimilars in rheumatology: recommendations for regulation and use in Middle Eastern countries

The increasing availability of biosimilar medicines in Middle Eastern regions may provide an opportunity to increase the number of rheumatology patients who have access to traditionally more expensive biologic medicines. However, as well as a lack of real-world data on the use of biosimilar medicines in practice, the availability of intended copies in the region may undermine physician confidence in prescribing legitimate biosimilar medicines. There is a need for regional recommendations for healthcare professionals to ensure that biosimilar drugs can be used safely. Therefore, a literature search was performed with the aim of providing important recommendations for the regulation and use of biosimilar medicines in the Middle East from key opinion leaders in rheumatology from the region. These recommendations focus on improving the availability of relevant real-world data, ensuring that physicians are aware of the difference between intended copies and true biosimilars and ensuring that physicians are responsible for making any prescribing and switching decisions.     

Fertility preservation for boys and adolescents facing sterilizing medical therapy

Improvements in childhood cancer survival have allowed boys and their families to increasingly focus on quality of life after therapy, particularly their future ability to father children. Treatments should maintain comprehensive cancer care goals and consider the long-term quality of life of these children. While semen cryopreservation is a well-established method of fertility preservation for post-pubertal children, the use of cryopreserved pre-treatment testicular tissue represents a promising, yet experimental method of fertility preservation for prepubertal males facing sterilizing therapy. Healthcare providers should counsel families about the fertility risks of therapy, discuss or refer patients for standard fertility preservation options, and consider experimental approaches to fertility preservation while being mindful of the ethical questions these treatments raise.     

Are Pathogenic Leptospira Species Agents of Community-Acquired Pneumonia? Case Reports of Leptospirosis Presenting as Pneumonia

We report four Indonesian cases meeting the clinical and radiological criteria for community-acquired pneumonia and other findings suggestive of leptospirosis. Quantitative PCR (qPCR) analyses of serum and urine samples and serology confirmed the diagnosis of leptospirosis in each. Results of qPCR analysis of throat swabs were concordant with those obtained with acute-phase serum samples, which suggests its potential for use as a noninvasive diagnostic tool for leptospirosis.     

Metastatic melanoma with balloon/histiocytoid cytomorphology after treatment with immunotherapy: A histologic mimic and diagnostic pitfall

Epithelioid cells with foamy cytoplasm (histiocytoid features) are typical histopathologic findings among benign and malignant histiocytic neoplasms such as xanthoma and atypical fibroxanthoma. However, these changes are unusual in melanoma, which is typically composed of nested and variably pigmented atypical epithelioid cells. Here, we report a patient with metastatic melanoma in lymph nodes presenting with prominent balloon cell/histiocytoid features expressing melanocytic markers, after treatment with nivolumab. This report suggests that the spectrum of neoplasms with histiocytoid features should be expanded to include melanoma, a pattern that, to the best of our knowledge, is uncommon, especially in the setting of post‐neoadjuvant therapy.
