Background: Vascularized lymph node transfer (VLNT) is traditionally performed in patients with advanced-stage lymphedema. To enhance and promote the physiological effects of VLNT, lymphatic system transfer (LYST) was developed. In this technique, lymph nodes and a portion of their corresponding afferent lymphatic vessels are transferred to stimulate lymphangiogenesis. This study presented our experience, pearls, and pitfalls of using superficial circumflex iliac artery perforator LYST.
Methods: A retrospective review of patients treated with LYST for lymphedema treatment from July 2018 to March 2022 was included. Patient characteristics, perioperative data, and long-term outcomes were analyzed.
Results: Eight patients with unilateral lower-extremity lymphedema underwent LYST. The mean follow-up duration was 39.0 (24.0-60.0) months. The mean improvement in the excess volume percentage compared to the unaffected limb was 11.2% (100% improvement to 0% worsening) at the last follow-up, with statistical significance (p < 0.001). The incidence of cellulitis decreased with statistical significance (p = 0.025).
Conclusion: A long-term study on using LYST flaps in lymphedema treatment has not been previously performed. This study showed that the LYST procedure provides reliable and effective long-term outcomes in treating patients with advanced-stage lymphedema.

Central Laboratory, Chongqing Public Health Medical Centre, Chongqing, China.
Background: In acquired immunodeficiency syndrome patients, Talaromyces marneffei infections are mostly disseminated and may involve the skin, mucosa, respiratory system, digestive system, lymphatic system, and as some reports indicate, the nervous system. Mp1p, a cell wall-specific polysaccharide in Talaromyces marneffei, is used for laboratory diagnosis of Talaromyces marneffei in blood and urine samples. However, Cerebrospinal fluid Mp1p diagnosis of Talaromyces marneffei central nervous system infection has not been reported.

Background: To analyze the safety and efficacy of microsurgical subinguinal varicocelectomy(MSV) performed with and without preservation of all testicular arteries and lymphatic system.
Methods: All of the 98 patients with varicocele who underwent MSV were included in the analysis. Fifty-eight male patients surgically underwent MSV with preservation of all testicular arteries and lymphatic system(Group 1).
Prognostic significance of lymphovascular invasion in pN0 stage gastric cancer: a propensity score matching analysis.

Article Synopsis
- - The study investigates how lymphovascular invasion (LVI) affects overall survival in gastric cancer patients at pN0 stage after they've undergone surgery to remove the tumor.
- - Out of 497 patients reviewed, 19.9% had LVI, which was linked to significantly poorer survival rates; further analysis identified LVI and the number of examined lymph nodes as independent predictors of survival.
- - The findings suggest that for better outcomes, it is crucial to dissect more than 15 lymph nodes during surgery for patients with pN0 stage gastric cancer, especially those with LVI.

Dynamic contrast-enhanced magnetic resonance lymphangiography is a high-resolution imaging technique that has emerged as the preferred method for evaluating lymphatic anatomy and flow dynamics due to its precise anatomical detail. The lymphatic system has a complex anatomical distribution, and variability is common among individuals with cardiac abnormalities, particularly congenital heart disease. Lymphatic imaging has recently been revolutionized by the introduction of MR lymphangiography.

Article Synopsis
- - The study aims to assess how often the submandibular gland (SMG) is affected in patients with oral cavity squamous cell carcinoma (OSCC) and whether it can be preserved during treatment.
- - Researchers analyzed data from 238 patients treated from January 2018 to October 2022, focusing specifically on 10 individuals with tongue squamous cell carcinoma who received postoperative radiotherapy and aimed to limit the radiation dose to the SMG.
- - Findings indicate that SMG involvement in OSCC is uncommon, and with careful planning, it's possible to reduce radiation exposure to the SMG while still treating the cancer effectively.
