The pregnancy-associated breast cancer is one of the most common malignancy developed during pregnant period and occupies 1-2% of the all breast cancer patients. There is no evidence to implicate pregnancy or lactation in either the etiology and the progression of breast cancer. Careful breast examination early in the pregnancy is very important to find solid masses before breast engorgement hides them. But unfortunately, delay in the diagnosis is common and most of patients with operable primary lesions have positive axillary lymph nodes. The treatment of choice is the modified radical mastectomy and adjuvant chemotherapy. The authors report a patient of breast cancer diagnosed and treated during pregnancy with review of literature.

Colorectal cancer is one of the most common cancers globally, ranking second for the number of cancer-related deaths. Metastasis has been reported as the main cause of death in patients with colorectal cancer. Peroxisome proliferator-activated receptor gamma (PPAR-γ) is a transcription factor that functions as a tumor suppressor by inhibiting cellular proliferation, migration, and invasion. In our previous efforts to generate natural product-motivated PPAR-γ ligands, the compounds 1 and 2 were obtained. These compounds activated PPAR-γ and inhibited the migration and invasion of HCT116 colorectal cancer cells, and they were also found to inhibit the epithelial-to-mesenchymal transition, which is a key process in cancer metastasis. Compounds 1 and 2 upregulated expression of the epithelial marker (E-cadherin), and downregulated expression of the mesenchymal marker (N-cadherin) and transcriptional factor (Snail). Therefore, the PPAR-γ agonists 1 and 2 could serve as a valuable model for the study on anti-metastatic leads for the treatment of colorectal cancer.

Objective: To investigate the effect of tumor necrosis factor (TNF)-alpha on the production of macrophage migration inhibitory factor (MIF), which might have important roles in the immune mediated inflammatory response of Behcet's syndrome. Methods: Sixty two patients with Behcet's syndrome and thirty healthy controls were included in this study. The concentrations of TNF-alpha in sera were determined by enzyme-linked immunosorbent assay (ELISA). Peripheral blood mononuclear cells (PBMCs) from eleven patients with Behcet's syndrome were cultured for 48 hours with various concentration of TNF-alpha. The concentrations of MIF in sera and culture supernatants were determined by ELISA. Results: Serum levels of TNF-alpha were significantly higher in patients with Behcet's syndrome than in healthy controls. TNF-alpha dose-dependently increased MIF production from PBMCs in patients with Behcet's syndrome. Serum levels of TNF-alpha tended to correlate with serum levels of MIF, although did not reach statistical significance. Conclusion: Upregulation of MIF production by increased levels of TNF-alpha in patients with Behcet's syndrome might be related to the pathogenesis of Behcet's syndrome.

BACKGROUND: Patients with malignancy are considered to be at high risk of severe pandemic influenza A/H1N1 2009. This study was conducted to identify the severity of pandemic influenza A/H1N1 2009 among patients with malignancy. MATERIALS AND METHODS: Between August 2009 and December 2009, we reviewed clinical data and medical records of 31 patients with malignancy and 63 hospitalized patients without malignancy. RESULTS: Eighty-three patients with laboratory-confirmed pandemic influenza A/H1N1 2009 were admitted. The rate of ICU admission was higher among patients with malignancy (without malignancy 13% vs with malignancy 35%, P=0.024). The mortality rate was higher among patients with malignancy (without malignancy 6% vs with malignancy 25%, P=0.033). Patients using immunosuppressants showed a higher rate of lower respiratory tract infection (83% vs 24%, P=0.013). CONCLUSIONS: Pandemic influenza A/H1N1 2009 in patients with malignancy was more severe than in patients without malignancy.

OBJECTIVE: To evaluate the feasibility of robotic single-site myomectomy (RSSM). METHODS: Medical records of 355 consecutive women who underwent robotic-assisted laparoscopic myomectomy were retrospectively reviewed. Clinical characteristics were compared between multi-site and single-site systems. After 1:1 propensity score matching for the total myoma number, largest myoma size, and total tumor weight (105 women in each group), surgical outcomes were also compared between the 2 systems. RESULTS: A total of 105 (29.6%) and 250 (70.4%) women underwent RSSM and robotic multi-site myomectomy (RMSM), respectively. RSSM was more commonly performed in women with lower body mass index (21.6 vs. 22.5 kg/m2, P=0.014), without peritoneal adhesions (7.6% vs. 24.8%, P < 0.001), and less (2.6 vs. 4.6, P < 0.001) and smaller (6.3 vs. 7.7 cm, P < 0.001) myomas compared to RMSM. After propensity score matching, the largest myoma size (P=0.143), total myoma number (P=0.671), and tumor weight (P=0.510) were not significantly different between the 2 groups. Although the docking time was significantly longer in the RSSM group (5.1 vs. 3.8 minutes, P=0.005), total operation time was similar between RSSM and RMSM groups (145.9 vs. 147.3 minutes, P=0.856). Additionally, hemoglobin decrement was lower in the RSSM group than in the RMSM group (1.4 vs. 1.8 g/dL, P=0.009). No surgical complication was observed after RSSM, while 1 ileus and 2 febrile complications occurred in women that underwent RMSM (0% vs. 2.9%, P=0.246). CONCLUSION: Although RMSM is preferred for women with multiple large myomas in real clinical practice, RSSM seems to be a feasible surgical method for less complicated cases, and is associated with minimal surgical morbidity.

Purpose:
There are many studies regarding the increased relationship between pregnancy outcomes of singleton with endometriosis. However, there was limited evidence of twin pregnancies with endometriosis. This study aimed to compare the pregnancy outcomes and complications in twin pregnancies with or without endometriosis in a single institution.
Materials and Methods:
From January 2011 to July 2022, a retrospective analysis of twin pregnancies was conducted. The endometriosis group included patient with histological or visual confirmation before pregnancy or during cesarean section. Pregnancy outcomes and complications were compared between the two groups.
Results:
Out of 1714 patients examined, 127 (7.4%) were included in the endometriosis group. Maternal body mass index (BMI) was lower in the endometriosis group (p<0.001). There were no significant differences in maternal age, mode of conception, chorionicity, and pregnancy outcomes, such as gestational age at delivery (p=0.835) and the preterm birth rate (p=0.579). The endometriosis group had a significantly higher rate of obstetrical complication: small for gestational age (SGA) <10% (p=0.029). However, after adjustment for BMI, the endometriosis group showed no statistical significance in obstetrical complications, including SGA (adjusted odds ratio, 1.568; 95% confidence interval, 0.984–2.499; p=0.059).
Conclusion
Twin pregnancies with endometriosis were not related to adverse effects on pregnancy outcomes and obstetrical complications. To confirm these outcomes, further large prospective studies are required.

The interleukin-33 (IL-33)/ST2 pathway has emerged as an intercellular signaling system that participates in antigen-allergen response, autoimmunity and fibrosis. It has been suggested that IL-33/ST2 signaling has been involved in the pathogenesis of rheumatoid arthritis (RA), because IL-33 and its receptor have been specifically mapped to RA synovium. The aim of this study was to determine the levels of IL-33 and sST2 in sera and synovial fluids in patients with RA. The serum level of IL-33 was significantly higher in patients with RA (294.9 +/- 464.0 pg/mL) than in healthy controls (96.0 +/- 236.9 pg/mL, P = 0.002). The synovial fluid level of IL-33 was significantly higher in RA patients than in osteoarthritis patients. The level of serum sST2 was higher in RA patients than in healthy controls (P = 0.042). A significant relationship was found between the levels of IL-33 and IL-1beta (r = 0.311, P = 0.005), and IL-33 and IL-6 (r = 0.264, P = 0.017) in 81 RA patients. The levels of IL-33, sST2 and C-reactive protein decreased after conventional disease-modifying antirheumatic drugs treatment in 10 patients with treatment-naive RA. Conclusively, IL-33 is involved in the pathogenesis of RA and may reflect the degree of inflammation in patients with RA.

OBJECTIVE: To evaluate clinical significance of interleukin 15 (IL-15) in patients with Behcet's disease (BD). METHODS: Serum samples were obtained from 31 patients with BD and 29 healthy controls. BD patients were divided into active and inactive group according to the presence of clinical manifestations on the day of sampling. Serum levels of IL-15 and IL-8 were measured by sandwich enzyme-linked immunosorbent assay (ELISA). RESULTS: Serum levels of IL-15 and IL-8 were significantly higher in BD patients than in healthy controls (117.2+/-26.2 pg/ml versus 51.8+/-15.4 pg/ml, p<0.01, 287.7+/-100.9 pg/ml versus 138.5+/-17.2 pg/ml, p<0.01, respectively). There was a significant correlation between serum levels of IL-15 and IL-8 IL-15 levels compared with those without it (161.1+/-68.8 pg/ml versus 96.4+/-3 4 . 8pg/ml, p<0.05). Serum levels of IL-15 and IL-8 tended to be higher in active group than in inactive group, but didn't reach statistical significance. CONCLUSION: Serum level of IL-15 was elevated in patients with BD, especially those with uveitis, but it did not seem to be useful as a marker of disease activity in BD.

Herpes virus entry mediator (HVEM) is a newly discovered member of the tumor necrosis factor receptor (TNFR) superfamily that has a role in herpes simplex virus entry, in T cell activation and in tumor immunity. We generated mAb against HVEM and detected soluble HVEM (SHVEM) in the sera of patients with various autoimmune diseases. HVEM was constitutively expressed on CD4(+)and CD8(+)T cells, CD19(+)B cells, CD14(+)monocytes, neutrophils and dendritic cells. In three-way MLR, mAb 122 and 139 were agonists and mAb 108 had blocking activity. An ELISA was developed to detect sHVEM in patient sera. sHVEM levels were elevated in sera of patients with allergic asthma, atopic dermatitis and rheumatoid arthritis. The mAbs discussed here may be useful for studies of the role of HVEM in immune responses. Detection of soluble HVEM might have diagnostic and prognostic value in certain immunological disorders.
