A higher number of exhausted local PD1+, but not TIM3+, NK cells in advanced endometriosis.

Endometriosis (EMT) is a chronic inflammatory disease characterized by the presence and growth of endometrial-like glandular epithelial and stromal cells outside the uterus. Natural Killer (NK) cell dysfunction/exhaustion has been shown in patients with EMT. In this case-control study, we compared the frequency of exhausted PD-1 or TIM-3 positive NK cells in peripheral blood (PB) and peritoneal fluid (PF) of women with advanced endometriosis to control fertile women. PB and PF were collected from women aged 25-40 who underwent the laparoscopic procedure, including 13 stages III/IV endometriosis and 13 control samples. Multicolor flowcytometry was used to compare the frequency of PD-1 or TIM-3 positive NK (CD3-CD56+) cells in PB and PF of two groups. We demonstrated a higher percentage of PD-1+ NK cells in the peritoneal fluid of patients with endometriosis rather than controls (P-value = 0.039). This significance was related to stage IV of endometriosis (P-value = 0.047). We can not show any significant difference in the number of PD-1 or TIM-3 positive NK cells in peripheral blood. Our results suggest a local exhausted NK cell response in endometriosis that can be a leading factor in the endometriosis pathogenesis.

Macrophage's role in solid tumors: two edges of a sword.

The tumor microenvironment is overwhelmingly dictated by macrophages, intimately affiliated with tumors, exercising pivotal roles in multiple processes, including angiogenesis, extracellular matrix reconfiguration, cellular proliferation, metastasis, and immunosuppression. They further exhibit resilience to chemotherapy and immunotherapy via meticulous checkpoint blockades. When appropriately stimulated, macrophages can morph into a potent bidirectional component of the immune system, engulfing malignant cells and annihilating them with cytotoxic substances, thus rendering them intriguing candidates for therapeutic targets. As myelomonocytic cells relentlessly amass within tumor tissues, macrophages rise as prime contenders for cell therapy upon the development of chimeric antigen receptor effector cells. Given the significant incidence of macrophage infiltration correlated with an unfavorable prognosis and heightened resistance to chemotherapy in solid tumors, we delve into the intricate role of macrophages in cancer propagation and their promising potential in confronting four formidable cancer variants-namely, melanoma, colon, glioma, and breast cancers.

Assessment of the clinical outcomes and complications of hysteroscopic and laparoscopic approaches in the treatment of symptomatic isthmocele: An observational study.

OBJECTIVES: To investigate the outcomes of patients undergoing laparoscopic or hysteroscopic approaches for isthmoplasty. METHODS: A total of 99 isthmocele patients with an average age of 38.45 ± 4.72 years were included in the 2 years of this retrospective cohort study. Forty-five underwent laparoscopic and 54 underwent hysteroscopic isthmocele excision and myometrial repair. RESULTS: Pain scores were significantly higher in the hysteroscopy group before the procedure, but there were no significant pain score differences after the surgery. In 1 year of follow up, dysmenorrhea and dyspareunia were higher among hysteroscopy patients. Furthermore, hysteroscopy significantly improved postmenstrual spotting after surgery better than laparoscopy, but in the follow up, there was no significant difference between the two groups in this regard (mean rank for hysteroscopy vs. laparoscopy: 32.30 vs. 37.48, U = 418, P = 0.29). CONCLUSION: In patients with a history of infertility, ectopic pregnancy, lower gravidity, lower parity, and a lower number of cesarean sections, laparoscopic isthmoplasty is preferred over the hysteroscopic approach. Both methods have similar effects on midcycle vaginal bleeding, duration of postmenstrual spotting, and pain. However, a higher rate of dyspareunia and dysmenorrhea could be associated with hysteroscopy.

Trauma-induced pemphigus: a case series of 36 patients.

BACKGROUND AND OBJECTIVES: Pemphigus is a group of autoimmune diseases characterized by intraepidermal acantholytic blisters. Isomorphic responses, or Koebner phenomenon (KP), defined as the appearance of typical lesions of a disease following trauma are rarely reported in pemphigus. Our aim was to present patients who developed new pemphigus lesions as a result of skin trauma. PATIENTS AND METHODS: The medical files of pemphigus patients from the Autoimmune Bullous Diseases Research Center, who had a history of trauma before the onset or flare of their disease, between 1999 and 2013 were reviewed. RESULTS: Thirty-six pemphigus vulgaris (PV) patients had a history of trauma. Thirteen patients developed new-onset PV and the other 23 had previously been diagnosed with PV. Pemphigus lesions developed most often following major surgeries including abdominal, orthopedic, and chest surgeries as well as dental procedures, blunt physical trauma, and skin surgeries. Moreover, post-cataract laser surgery, burns, radiation therapy, and physiotherapy were also shown to induce pemphigus. Mean time between trauma and lesions was 4.7 weeks for recurrent PV and 15.0 weeks for new-onset PV. CONCLUSIONS: Unnecessary surgery and blunt trauma should be avoided in pemphigus patients. Furthermore, posttraumatic pemphigus should be suspected in poorly healing surgical wounds and confirmatory biopsies are mandatory.
