Background: Kaposi Sarcoma (KS) is a multifocal angioproliferative neoplasm characterized by inflammation, oedema, neoangiogenesis and spindle cell proliferation. The pathogenesis of human immunodeficiency virus (HIV)-associated KS (HIV-KS) is multifactorial. HHV-8 is an essential factor but not in itself sufficient to cause HIV-KS, the development of which is influenced by HIV, by increased production of cytokines and by growth factors. Whether HIV-KS is a true malignancy or a reactive hyperplastic inflammatory condition is debatable.
Results And Conclusion: Oedema of the face, legs and hands is a prominent feature of HIV-KS and is probably caused by lymphoedema related to the HIV-KS lesions. The cases of two HIV-seropositive subjects with KS-associated facial lymphoedema are reported. Extensive oral HIV-KS in association with facial oedema in the absence of anti-retroviral treatment appears to be an indication of a poor prognosis.

Background: The World Health Organization launched the Global Programme to Eliminate Lymphatic Filariasis in 2000, which aimed at eradicating the disease by 2030. This goal depends on community mass drug administration and essential care. Despite these efforts, many rural communities still face untreated lymphatic filariasis and lack access to treatment and self-management.

Article Synopsis
- - The study investigates the prenatal and postnatal features, along with genetic traits, of Lymphedema-Distichiasis syndrome (LDS) in two Chinese families with FOXC2 gene mutations.
- - Genetic analysis revealed pathogenic variants in the FOXC2 gene for both families, with literature review yielding a total of 117 identified LDS patients, including prenatal signs in 13 cases and postnatal manifestations in 110.
- - Key prenatal symptoms of LDS include increased nuchal translucency and fetal edema, while postnatal symptoms commonly feature distichiasis and lymphedema, with only a few cases exhibiting signs before and after birth.

Objectives: Complications following breast cancer treatment result in chronic upper limb disabilities. To plan an informed and effective rehabilitation for timely intervention to prevent, mitigate, or manage the functional impairments for breast cancer survivors, especially in settings with limited resources, the burden of upper limb disabilities needs to be ascertained. This study examined upper limb disabilities and associated factors among breast cancer survivors.
