ng of the proteome topology and 3D tissue reconstruction could be expected.We report a case of torsion in an otherwise-normal ovary with a giant hematosalpinx. A 23-year-old woman presented with complaints of abdominal pain and nausea. At initial visit, there was few abnormal findings of imaging tests, and we made a diagnosis of ovarian hemorrhage. Three days later, she came back with increased symptoms, and we detected the mass of a complex solid cystic structure with a unilocular cyst much larger than solid component. A diagnostic laparoscopy was performed immediately, and we could make a diagnosis of torsion in an otherwise-normal ovary with a giant hematosalpinx. We performed a salpingectomy and could preserve her ovary. This is the first case of torsion in an otherwise-normal ovary with a giant hematosalpinx which enlarged to a greater extent than the ovary.Pemphigus vulgaris (PV) is a chronic, autoimmune, intraepidermal blistering disease of the skin and mucous membranes. The first clinical manifestation is often the development of intraoral lesions, and later, the lesions involve the other mucous membranes and skin. The etiological factors of this disease still remain unknown, although the presence of autoantibodies is consistent with an autoimmune disease. A 73-year-old man had bullous lesions on gingiva, oral mucosa first, then scalp, trunk, and face. An oral medicine specialist suspects the lesion in differential diagnosis in the first presentation of oral lesions and follows up the patient, and then these bullous lesions presented on the skin. In this article, a patient had received oral prednisolone (80 mg/kg/day) and azathioprine, then tapered oral prednisolone to 40 mg/day, with a reduction of 5 mg/day every three weeks. The patient shows remission of these lesions, and complication of this treatment includes osteoporosis, hyperglycemia, and hypertension.Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a viral infection with multiorgan manifestations that may affect the oral mucosa. The full range of oral manifestations of COVID-19 are unknown, and there are limited reports describing the features of oral manifestations of COVID-19, including taste loss, oral lesions, and xerostomia. The aim of this study is to report a case of oral erythema multiforme (EM) manifesting as oral, lip, and skin lesions in a COVID-19 patient. The presence of oral lesions in the late stage of COVID-19 could be related to weak patient immunity or related therapies.Severe pneumonitis induced by nivolumab, an anti-programmed cell death-1 monoclonal antibody, is a rare but potentially fatal immune-related adverse event. In cases of steroid-refractory pneumonitis, an appropriate therapeutic strategy using anti-tumor necrosis factor-α (TNF-α) antibody has not been established. A 59-year-old female was diagnosed with hypopharyngeal squamous cell carcinoma. Previous therapies including chemoradiotherapy and throat laryngectomy were performed, but metastatic recurrence appeared in the intrapulmonary and mediastinal lymph nodes. The patient was administered nivolumab. On the 14th day of nivolumab administration, the patient experienced dyspnea and computed tomography of the chest showed multiple consolidations in the right lung. She was diagnosed with nivolumab-induced pneumonitis. Because the pneumonitis was refractory to steroid therapy, she was administered infliximab, and the pneumonitis improved. On the 72nd and 101st days of nivolumab administration, nivolumab-induced pneumonitis re-appeared with an elevated serum TNF-α concentration. In each occurrence of pneumonitis, repetitive administration of infliximab improved the pneumonitis. Repetitive administration of infliximab may be effective for treating recurrent nivolumab-induced pneumonitis that is associated with an increased serum TNF-α concentration.The current standard of care for locally advanced rectal cancer (LARC) includes preoperative chemoradiation, followed by total mesorectal excision and adjuvant chemotherapy. This multimodality treatment improves local control but is associated with low compliance rates without clear beneficial effects on overall survival (OS) and distant metastasis. In this retrospective study, the charts of patients diagnosed with cT3/4 or cT2-node-positive rectal cancer between January 2011 and June 2019 were reviewed. The chemoradiation therapy (CRT) group received a long course of CRT with capecitabine followed by surgery and adjuvant chemotherapy. The total neoadjuvant therapy (TNT) group received 6 cycles mFOLFOX and a short course of radiation therapy followed by surgery. A total of 81 patients were included, among which 55 (67.9%) received CRT and 26 (32.1%) received TNT. In the CRT group, 15 (27.3%) patients achieved pathologic complete response (pCR) compared with 10 (38.5%) in the TNT group (P=0.22). A total of 19 (35.8%) cases in the CRT group downstaged to pT0N0 or pT1N0 compared with 11 (42.3%) in the TNT group (P=0.33). The 2-year disease-free survival (DFS) rate was 81.0% in the TNT group and 84.0% in the CRT group (P=0.15). Out of 55 patients in the CRT group, 30 patients received adjuvant chemotherapy, 22 (40.0% of CRT cases) of which completed a full course. All 26 patients in the TNT group received neoadjuvant chemotherapy, where 22 (84.6%) patients took a full course (P less then 0.001). In conclusion, the present study revealed that patients treated with TNT were more compliant to chemotherapy than those treated with CRT. A numerically higher pCR rate, and nodal and tumor downstaging were noted in the TNT group without significance. No difference was noted in the 2-year DFS. Longer follow-up is required.Chemotherapy-induced nausea and vomiting (CINV) can cause anorexia, weight loss and deterioration of patient quality of life. It is one of the most unpleasant adverse effects of chemotherapy treatment regimens. For the optimal treatment of gastrointestinal symptoms during urothelial carcinoma chemotherapy, the present study investigated the association between gastrointestinal symptoms and therapeutic effects of gemcitabine plus platinum [cisplatin (GC) or carboplatin (GCa)] therapies. The incidence and frequency of nausea/vomiting with GC split therapy (gemcitabine, 1,000 mg/m2 on days 1 and 8; split-dose cisplatin, 35 mg/m2 on days 1 and 8; 21-day schedule) and GCa therapy [gemcitabine, 750-1,000 mg/m2 on days 1, 8 and 15; carboplatin, area under the blood concentration-time curve=5 mg min/ml (Calvert formula) on day 2; 28-day schedule] were lower compared with those of GC therapy (gemcitabine, 1,000 mg/m2 on days 1, 8 and 15; single-dose cisplatin 70 mg/m2 on day 2; 28-day schedule). However, no differences in therapeutic outcomes were observed among therapies. GCa therapy, regardless of renal function, and GC split therapy demonstrated significant increases compared with GC therapy in alleviating gastrointestinal symptoms associated with cancer chemotherapy in patients with urothelial carcinoma. Overall, these results suggested that split-dose cisplatin administration or the use of carboplatin instead of cisplatin may be useful in patients who experience CINV without compromising treatment effectiveness.Small cell lung cancer (SCLC) is exceptionally responsive to chemotherapy and radiotherapy. In relapsed patients, particularly in resistant/refractory cases, the progression of disease occurs rapidly with second-line agents. Topotecan (TOPO), a camptothecin analog, is the only agent able to increase overall survival (OS) compared with the best supportive care alone. However, the efficacy of platinum-based chemotherapy rechallenge or other agents has not been systematically explored. In the present review, published articles, which evaluated outcome and toxicity associated with TOPO or non-TOPO-based chemotherapy in patients with SCLC from inception to September 2020 were systematically searched and identified by searching the PubMed, EMBASE and Cochrane Library databases. The primary outcome of interest was the risk of death (OS), and the secondary endpoints were risk of progression progression-free survival (PFS), overall response rate (ORR) and G3-4 hematological toxicities. A total of nine studies were included in quantitative synthesis for a total of 1,689 patients. They included platinum-based rechallenge, anthracycline-based combinations or camptothecin analogs. TOPO did not improve OS with respect to other therapies [hazard ratio (HR), 0.92; 95% confidence interval (95% CI), 0.78-1.09; P=0.33]. Similarly, PFS was similar in the two arms (HR, 1.1; 95% CI, 0.72-1.67; P=0.66). The ORR was not statistically higher with non-TOPO agents (relative risk, 1.53; 95% CI, 0.95-2.48). In subgroup analysis, combination chemotherapy was associated with an improved PFS but not OS or ORR compared with TOPO alone (HR, 1.85; 95% CI, 1.52-2.24; P less then 0.01). The rates of G3-4 anemia, febrile neutropenia and neutropenia were similar. In conclusion, in patients with relapsed SCLC, TOPO was associated with a similar survival, PFS and ORR as other agents. However, polychemotherapy was associated with improved PFS.The role of the neutrophil-to-lymphocyte ratio (NLR) in predicting sensitivity to chemotherapy and prognosis has attracted great interest in several types of cancer. In the present study, the correlation between pre-chemotherapy NLR and sensitivity to platinum-based chemotherapy and prognosis in patients with advanced serous ovarian carcinoma was examined by retrospectively reviewing the medical records of 50 patients with stage III-IV serous ovarian carcinoma from 2005 to 2012. Patients were divided into high-NLR (32 patients) and low-NLR (18 patients) groups according to a cutoff value of 2.47. This cutoff was calculated using a receiver operating characteristic (ROC) curve that demonstrated 84% specificity and 60% sensitivity. Patient characteristics, sensitivity to platinum-based chemotherapy and prognosis were subsequently compared. The results revealed no significant difference in patient characteristics between the two groups. In the low-NLR group, 14 of 18 patients (77.8%) were sensitive to platinum-based chemotherapy, whereas 11 of 32 were sensitive in the high-NLR group (34.4%) (P=0.007). Overall and disease-free survival (DFS) were significantly longer in the low-NLR than in the high-NLR group (P=0.013 and P=0.043, respectively). The current results suggested that pre-chemotherapeutical NLR may serve as a biomarker of sensitivity to platinum-based chemotherapy and prognosis in patients with advanced serous ovarian carcinoma.The one-step nucleic acid amplification (OSNA) assay is a molecular method used for detecting breast cancer (BC) metastasis in sentinel lymph nodes (SLNs). However, this method has a major disadvantage, since it prevents tissue structure analysis, while only one molecular marker can be evaluated, namely cytokeratin 19 mRNA. The aim of the present study was to evaluate whether an OSNA-discarded sample could be suitable for the gene expression analysis of the SLN microenvironment. The remaining intermediate phase of the centrifuged SLN homogenate obtained from the OSNA assay of samples from two patients with BC was used for mRNA extraction. Subsequently, the expression of five genes, namely forkhead box, cluster of differentiation 4 and three control genes, was determined by reverse transcription-quantitative PCR analysis. UNC3866 The results demonstrated that high-quality RNA was extracted. Therefore, this RNA may be used for gene expression analyses to predict novel molecular biomarkers associated with immuno-inflammatory microenvironment.
