Abstract
Background Definitive diagnosis of histiocytic sarcoma (HS) in dogs is relatively difficult by conventional histopathological examination because objective features of HS are not well defined. Hypothesis Quantitative analysis of mRNA expression of selected cellular surface antigens (SAs) specific to HS in dogs can facilitate objective and rapid diagnosis. Animals Dogs with HS (n = 30) and dogs without HS (n = 36), including those with other forms of lymphoma (n = 4), inflammatory diseases (n = 6), and other malignant neoplasias (n = 26). Methods Retrospective clinical observational study. Specimens were collected by excisional biopsy, needle core biopsy, or fine needle aspiration. To determine HS detection efficacy, mRNA expression levels of selected SAs specific to HS in dogs, including MHC class IIα, CD11b, CD11c, and CD86, were quantitatively analyzed using real‐time quantitative polymerase chain reaction. Results Each SA mRNA expression level was significantly higher in HS dogs than in non‐HS dogs (P = .0082). Cutoff values for discriminating between HS and non‐HS dogs based on these expression levels were calculated on the basis of receiver‐operating characteristic analysis. Accuracy of the cutoff values, including MHC class IIα, CD11b, CD11c, and CD86, was 87.9, 86.4, 86.4, and 84.8%, respectively. Conclusions and Clinical Importance Our results suggest that quantitative analysis of mRNA expression of the selected SAs could be an adjunctive diagnostic technique with high diagnostic accuracy for HS in dogs. Substantial investigation is required for exclusion of diseases with similar cell types of origin to lymphoma.

Abstract
The incidence of thoracic surgery for patients with arteriosclerosis has increased with the aging of society. Pulmonary resection is generally indicated for patients with coronary artery or aortic disease, following careful preoperative evaluations of cardiopulmonary function and oncological resectability. When preoperative coronary revascularization is required, percutaneous coronary intervention with a bare metal stent might be effective, due to the intermission of antiplatelet therapy during surgery. Furthermore, a" non-dissecting" technique that preserves mediastinal adhesion and divides the lung parenchyma is an option for pulmonary resection in patients who previously underwent coronary arterial bypass grafting (CABG) using the ipsilateral internal thoracic artery. Perioperative analgesic management with epidural anesthesia is quite important to stabilize hemodynamics and avoid the use of nonsteroidal anti-inflammatory drugs, which may influence potential renal dysfunction. Postoperative arterial fibrillation, which reduces blood flow in the coronary artery with low cardiac output, can be predicted based on preoperative serum brain natriuretic peptide level, and prevented by prophylactic atrial natriuretic peptide infusion and immediately controlled with an ultrashort-acting beta-blocker. Thus, special attention is required for surgical interventions that include pulmonary resection in patients with coronary artery or aortic disease.

Abstract
Thymoma-associated multi-organ autoimmunity is a rare, autoimmune disease that causes colitis, liver dysfunction and cutaneous graft-versus-host (GVH)-like skin damage. This paraneoplastic autoimmune disorder may be due to inadequate T cell selection in the tumour environment of the thymus. Although sporadic case reports have revealed its clinical features, little is known about its pathological mechanism. By comparing the skin-infiltrating T cell subsets with those of GVH disease (GVHD) and other inflammatory skin diseases, we sought to elucidate the pathological mechanism of thymoma-associated multi-organ autoimmunity. Histopathological and immunohistochemical analysis of skin biopsies was performed for three patients with thymoma-associated multi-organ autoimmunity. Histopathological findings of thymoma-associated multi-organ autoimmunity were indistinguishable from those of patients with acute GVHD, although the aetiologies of these diseases are completely different. The frequency of regulatory T cells (T(regs)) is reduced in cutaneous lesions and CD8+ cytotoxic T lymphocytes that massively infiltrate into the epidermis of patients with thymoma-associated multi-organ autoimmunity. Additionally, the ratio of T helper type 17 (Th17) cells to CD4+ cells in patients with thymoma-associated multi-organ autoimmunity and acute GVHD was higher than that in healthy controls, but similar to that in psoriasis vulgaris patients. Similarity of the skin-infiltrating T cell subsets with those of acute GVHD suggested that skin damage in patients with thymoma-associated multi-organ autoimmunity might be induced by self-reactive cytotoxic T lymphocytes under the diminished suppressive capacity of T(regs).

Abstract
OBJECTIVE To review a single center's experience in the management of twin pregnancies with conjoined fetuses. METHODS Retrospective study describing prenatal findings, delivery details, surgical treatment and perinatal outcome. RESULTS The study included 36 twin pregnancies with conjoined twins seen over a period of 12 years in a single tertiary hospital: 69.4% were thoracopagus, 13.9% parapagus, 8.3% omphaloischiopagus 5.6% omphalopagus and 2.8% cephalopagus. Cardiac defects were present in 91.6% of twin pairs and associated malformations were present in 61.8% of the cases: limb abnormalities in 36.1%, abdominal wall defects in 25.0%, cleft lip and/or palate in 13.9% and congenital diaphragmatic hernia in 5.5%. Surgical separation was considered not feasible and prognosis lethal in 30 (83.3%) cases. Termination of pregnancy was performed in 12 pregnancies of poor prognosis. Cesarean section was performed in all remaining cases. Five sets of twins underwent surgical separation and six children survived. Overall survival in our series was 8.3% and, among the livebirths, 13.6%. CONCLUSION Conjoined twin pregnancies should be referred to tertiary centers for detailed fetal anomaly and echocardiographic assessment to evaluate prognosis and determine the possibility of postnatal surgical separation.

Abstract
Living-donor lobar lung transplantation (LDLLT) is one of the final options for saving patients with pulmonary complications after hematopoietic stem cell transplantation (HSCT). We retrospectively investigated 19 patients who had undergone LDLLT after HSCT in Japan. Eight patients underwent LDLLT after HSCT in which one of the donors was the same living donor as in HSCT (SD group), while 11 received LDLLT from relatives who were not the HSCT donors (non-SD group). In the SD group, three patients underwent single LDLLT. The 5-year survival rate was 100% and 58% in the SD and non-SD groups, respectively. In the SD group, postoperative immunosuppression was significantly lower than in the non-SD group. Two patients died of infection and one died of post-transplant lymphoproliferative disease (PTLD) in the non-SD group, while only one patient died of PTLD 7 years after LDLLT in the SD group. Hematologic malignancy relapsed in two patients in the non-SD group. For the three single LDLLTs in the SD group, immunosuppression was carefully tapered. In our study, LDLLT involving the same donor as for HSCT appeared to have advantages related to lower immunosuppression compared to LDLLT from relatives who were not the HSCT donors.
