Background: Primary effusion lymphoma (PEL) is a lymphoid proliferation related to Kaposi sarcoma herpesvirus 8/human herpesvirus 8 (KSHV/HHV8) that affects mainly human immunodeficiency virus (HIV) infected individuals but can also occur in other immunodeficiency settings. It is characterized by lymphomatous effusions in different serous body cavities without the presence of a detectable tumor mass. The diagnosis is challenging and the clinical outcomes are poor. Aim: The aim of this paper is to report a rare case of PEL in a man who have sex with women (MSW) with HIV-1/2 infection, history of visceral Kaposi sarcoma (KS) and the development of a seronegative arthritis previous to the lymphoproliferative disease diagnosis. PEL presented with ascites, was treated with high-dose chemotherapy and autologous stem cell transplantation, with a good clinical outcome. Case Presentation: We describe a case of a 48-year-old HIV-1/2-infected patient from a high HHV8 seroprevalent country, hospitalized following a three-month history of increased abdominal volume and general constitutional symptoms. Laboratory data revealed normocytic normochromic anemia and a high level of lactate dehydrogenase. A diagnostic paracentesis was performed with cytology compatible with high-grade B-cell lymphoma. Peritoneal fluid cytology showed large lymphoid cells expressing leucocyte-common antigen CD45 without expression of the CD20 antigen (B-lymphocytes) and positivity for HHV8 by immunocytochemical staining, compatible with the diagnosis of PEL.

BACKGROUND In patients with metastatic colorectal cancer(mCRC),the treatment options are limited and have been proved to be affected by rat sarcoma virus(RAS)mutational *** RAS wild-type(wt)patients,the combination of antiepidermal growth factor receptor(EGFR)monoclonal antibodies with chemotherapy(CT)is more effective than CT *** the other hand,RAS-mutated patients are not eligible for treatment with anti-EGFR *** SUMMARY Eleven patients with initially RAS-mutated mCRC were followed from diagnosis to May *** the time of cell-free DNA determination,five patients had undergone one CT line,five patients had undergone two CT lines,and one patient had undergone three CT lines(all in combination with bevacizumab).At the second and third treatment lines[second line(2L),third line(3L)],patients with neo-RAS wt received a combination of CT and *** neo-RAS wt patients treated with anti-EGFR,our findings indicated an increase in progression-free survival for both 2L and 3L(14.5 mo,P=0.119 and 3.9 mo,P=0.882,respectively).Regarding 2L overall survival,we registered a slight increase in neo-RAS wt patients treated with anti-EGFR(33.6 mo vs 32.4 mo,P=0.385).At data cut-off,two patients were still alive:A RAS-mutated patient undergoing 3L treatment and a neo-RAS wt patient who received 2L treatment with anti-EGFR(ongoing).CONCLUSION Our case series demonstrated that monitoring RAS mutations in mCRC by liquid biopsy may provide an additional treatment line for neo-RAS wt patients.

目的旨在通过系统综述,确定针对复杂慢性病患者增强自我管理的干预措施,以改善慢性呼吸困难,为护理人员促进该类人群的自我管理提供依据。方法2023年12月,系统检索Medline、Scopus、Web of Science、CINAHL、Cochrane图书馆和乔安娜布里格斯研究所(Joanna Briggs Institute,JBI)循证实践数据库。对纳入研究进行数据提取和综合,研究人员采用Rayyan文献管理软件筛选标题及摘要,并依据JBI研究质量评估工具进行方法学质量评估。结果共纳入18项研究。这些研究探讨了针对慢性呼吸困难的各种干预措施,包括药物干预(氧气疗法和吸入疗法)和非药物方法(教育计划、呼吸练习、液体摄入管理、身体感知技术、同伴支持、情商培训和网络应用程序的使用)。这些干预措施减轻了患者情绪困扰,可以使患者在自我管理方面变得独立自主。结论促进复杂慢性病患者对慢性呼吸困难的自我管理需要采取综合方法,但目前研究中没有充分考虑到针对患者行为改变的干预措施,需要进一步开展相关研究完善干预措施。

Multiple Symmetric Lipomatosis (MSL) is a rare condition characterized by a symmetrical pattern of massive fatty deposits. This condition predominates in males, between 30 and 60 years. In this article, the authors present a case report of a 47-year-old man that resorted to consultation to perform routine medical exams, without any complaint associated. Physical examination shows multiple bilateral swellings in the proximal region of the upper limbs and analytically presents hyperuricemia, hypertriglyceridemia, hypercholesterolemia and changes in hepatic tests. CT revealed the presence of non-encapsulated homogeneous masses of adipose tissue in the proximal region of the limbs. Currently the patient is asymptomatic, being monitoring in consultation.

Hereditary lymphoedema type I is a congenital onset primary lymphoedema with autosomal dominant inheritance, which is characterized by the swelling of the lower body. In this article, the authors report a case of a 32-year-old woman with repeating episodes of swollen limbs. Imaging studies and genetic study were carried out and a Milroy’s syndrome diagnosis was established. The patient started sintomatic treatment of the edema, with fitting stockings and descompressive massage, with symptomatic benefit.
