RESUMO

BACKGROUND: Hand-foot skin reaction (HFSR) is the most common adverse event during sorafenib treatment in patients with hepatocellular carcinoma (HCC). In the present study, we aimed to investigate the role of urea cream in the prevention of HFSR or amelioration of HFSR severity. PATIENTS AND METHODS: Patients with HCC were treated with either placebo cream or urea cream for 12 weeks concomitantly with sorafenib treatment. HFSR development, the Hand-Foot Skin Reaction and Quality of Life (HF-QoL) questionnaire score, and adverse events were assessed at 2, 4, 8 and 12 weeks. RESULTS: Of the 288 patients, 247 patients, with 117 patients in the placebo control group and 130 patients in the urea cream group, were analysed. The urea cream group showed a trend towards a lower cumulative incidence of any-grade HFSR (log-rank, P = 0.247) and severe HFSR of grade II or higher (log-rank, P = 0.394) without statistical significance. In the incidence by time point, the incidence of severe HFSR of grade II or higher was significantly lower in the urea cream group than in the placebo control group at 2 weeks (13.8% versus 23.9%, P = 0.042). The urea cream group showed a significantly better HF-QoL questionnaire score than the placebo control group (11.8 versus 19.7, P = 0.014) at 12 weeks. CONCLUSIONS: Treatment with urea cream showed a lower incidence of severe sorafenib-induced HFSR at 2 weeks and reduced the tendency of HFSR development in HCC patients. Therefore, treatment with urea cream may be considered for prophylaxis or improvement of HFSR grade in HCC patients treated with sorafenib. TRIAL REGISTRATION: ClinicalTrials.gov (NCT03212625).

RESUMO

The anatomical position of the vermiform appendix varies among adults, and these variations are responsible for differences in the symptoms of appendicitis. However, to date no study has examined how and when these variations occur during fetal development. The present study examined horizontal sections of 27 midterm fetuses (crown rump length [CRL] 38-97 mm, gestational age approximately 8-15 weeks). There were 10 fetuses (CRL 56 mm or more) in which the cecum and appendix were in a posterosuperior site near the right kidney (postmigration phase), and 12 fetuses (CRL 39-72 mm) in which the ileocecal junction and appendix remained on the visceral surface of the liver in the anterior or anterolateral abdominal cavity (migration phase, after physiological umbilical herniation). Analysis of the 12 fetuses in the migration phase indicated that the appendix extended inferiorly in eight fetuses and superiorly in four fetuses. Likewise, a "preileal" appendix (a morphology in which the distal part of the appendix was in front of the terminal ileum) was present in eight of these fetuses. Extension of the appendix superiorly or inferiorly during the migration phase seems unrelated to the topographical relationship of the appendix with the terminal ileum at the postmigration phase in fetuses and in adults. Conversely, it seems likely that a retroileal appendix leads to a coiled appendix behind the ileocecal junction. "Guidance" by the liver surface seemed to be important for posterior migration, which ended with the ascent of the liver. Clin. Anat., 33:667-677, 2020. © 2019 Wiley Periodicals, Inc.

RESUMO

BACKGROUND AND AIMS: This study was performed to evaluate the treatment efficacy of endoscopic variceal obturation (EVO) in patients with gastric variceal bleeding (GVB) according to the type of varices. PATIENTS AND METHODS: All patients who were treated with EVO for bleeding from gastric varices (GVs) were included. Patients with a previous history of endoscopic treatment for GVB and those with accompanying portal vein invasion by hepatocellular carcinoma or other malignancy were excluded. RESULTS: Ninety-one patients with GVB were included. Mean age was 59.4±12.4 years and 72 (79.1%) patients were men. The types of varices were gastroesophageal varices (GOV) type 1 (GOV1), GOV2, and isolated gastric varices type 1 (IGV1) in 30 (33.3%), 35 (38.5%), and 26 (28.6%) patients, respectively. Hemostasis and GV obliteration were achieved in 88 (96.7%) and 81 (89.0%) patients, respectively. Among 81 patients with GV obliteration, GV recurred in 26 (32.1%) patients. The GV recurrence rate was significantly lower in patients with GOV1 than in those with GOV2 (P=0.007), while it was comparable between patients with GOV1 and IGV1 (P=0.111) and between patients with GOV2 and IGV1 (P=0.278). Variceal rebleeding occurred in 11 (13.6%) patients. GVB recurrence rate was significantly higher in patients with GOV2 than in those with GOV1 (P=0.034) and IGV1 (P=0.018), while it was comparable between patients with GOV1 and IGV1 (P=0.623). Mortality rate was comparable among the three groups. CONCLUSIONS: EVO was very effective in patients with GVB. GV recurrence and GV rebleeding were significantly lower in patients with GOV1 than in those with GOV2.

RESUMO

Inflammation is a response that protects the body from pathogens. Through several inflammatory signaling pathways mediated by various families of transcription factors, such as nuclear factor-κB (NF-κB), activator protein-1 (AP-1), interferon regulatory factors (IRFs), and signal transducers and activators of transcription (STATs), various inflammatory cytokines and chemokines are induced and inflammatory responses are boosted. Simultaneously, inhibitory systems are activated and provide negative feedback. A typical mechanism by which this process occurs is that inflammatory signaling molecules upregulate mitogen-activated protein kinase phosphatase-1 (MKP1) expression. Here, we investigated how kinases regulate MKP1 expression in lipopolysaccharide-triggered cascades. We found that p38 and c-Jun N-terminal kinase (JNK) inhibitors decreased MKP1 expression. Using specific inhibitors, gene knockouts, and gene knockdowns, we also found that tumor necrosis factor receptor-associated factor family member-associated nuclear factor κB activator (TANK)-binding kinase 1 (TBK1) and Janus kinase 2 (JAK2) are involved in the induction of MKP1 expression. By analyzing JAK2-induced activation of STATs, STAT3-specific inhibitors, promoter binding sites, and STAT3-/- cells, we found that STAT3 is directly linked to TBK1-mediated and JAK2-mediated induction of MKP1 expression. Our data suggest that MKP1 expression can be differentially regulated by p38, JNK, and the TBK1-JAK2-STAT3 pathway after activation of toll-like receptor 4 (TLR4). These data also imply crosstalk between the AP-1 pathway and the IRF3 and STAT3 pathways.

RESUMO

BACKGROUND: The prognostic performance of the albumin-bilirubin (ALBI) grade in hepatocellular carcinoma (HCC) as an objective method of assessing liver function was investigated. METHODS: Data from 2099 patients with HCC in Korea were collected and analyzed retrospectively. The discriminative performance of ALBI grade was compared with Child-Pugh (C-P) grade for different stages or treatments. RESULTS: The median follow up duration was 16.2 months (range: 1.0-124.9). The median survival times were 49.7 months for C-P grade A (65.8%), 12.4 months for C-P grade B (25.5%), and 4.2 months for C-P grade C (8.6%) (P < 0.001). The median survival times were 84.2 months for ALBI grade 1 (32.8%), 25.5 months for ALBI grade 2 (53.5%), and 7.7 months for ALBI grade 3 (13.7%) (P < 0.001). In early UICC stages, ALBI grade showed better discriminative performance than C-P grade. In curative treatments, ALBI grade also showed better discriminative performance than C-P grade (Harrell's C: 0.624 (C-P grade) vs 0.667 [ALBI grade]). CONCLUSIONS: ALBI grade provided better prognostic performance in survival analysis and better distribution of the grades than C-P grade in HCC, suggesting that ALBI grade could be a good alternative grading system for liver function in patients with HCC.

RESUMO

In general, solitary right aortic arch carries the left-sided ductus arteriosus communicating between the left subclavian and pulmonary arteries or the right-sided ductus connecting the descending aorta to the left pulmonary artery. Serial sections of fifteen 5- to 6-week-old embryos and ten 8- to 9-week-old fetuses suggested that the pathogenesis was unrelated to inversion due to dysfunction in gene cascades that control the systemic left/right axis. With inversion, conversely, the ductus or the sixth pharyngeal arch artery should connect to the right pulmonary artery. The disappearance of the right aortic arch started before the caudal migration of the aortic attachment of the ductus. Sympathetic nerve ganglia developed immediately posterior to both aortae, with a single embryonic specimen showing a large ganglion at the midline close to the union of the aortic arches. These ganglia may interfere with blood flow through the distal left arch, resulting in the ductus ending at the descending aorta behind the oesophagus. In another fetus examined, a midline shift of the ductus course resulted in the trachea curving posteriorly. Therefore, solitary right arch is likely to accompany abnormalities of the surrounding structures. The timing and site of the obstruction should be different between types: an almost midline obstruction near the aortic union needed for the development of the left-sided ductus and a distal obstruction near the left subclavian arterial origin needed for the development of the right-sided ductus. A mass effect of the sympathetic ganglia may explain the pathogenesis of any type of anomalous ductus arteriosus shown in previous reports of the solitary right arch.

RESUMO

BACKGROUND: Lasers have been proposed as an alternative treatment for axillary osmidrosis. OBJECTIVE: This study aimed to investigate the use of a neodymium:yttrium-aluminum-garnet laser with a wavelength of 1,444 nm for treating axillary osmidrosis. MATERIALS AND METHODS: Eighteen patients with axillary osmidrosis who underwent an operation with a 1,444-nm wavelength laser were included in this study. Operative parameters were as follows: pulse = 40 Hz and energy = 170 mJ. Total energy was approximately 2,000 to 3,400 J, and the operation time was 45 minutes. RESULTS: Statistically significant differences in the degree of malodor evaluated by both the patients (p = .001) and doctors (p = .012) were detected between preoperative and 6-month postoperative assessments. Sweat area was significantly reduced 6 months after the operation compared with preoperative values. Postoperative pain had subsided at day 7 in all but 1 patient. Two patients (11.1%) experienced superficial second-degree burns on the unilateral axilla; these burns were resolved fully. CONCLUSION: The laser with a wavelength of 1,444 nm was found to be a reliable method for the treatment of axillary osmidrosis, with advantages such as small wound size, rapidity of the procedure, inconspicuous scars, and speedy recovery and return to normal daily activities.

RESUMO

Angiosarcoma is a rare malignant tumor of soft tissue. Because angiosarcoma originates from endothelial cells, it can occur in any organ and shows aggressive clinical features. Most commonly, angiosarcoma initially presents as a cutaneous lesion. Lung metastasis from scalp angiosarcoma can develop pneumothorax. We report a case of multiorgan involvement of an angiosarcoma, including the scalp, initially presenting with hydropneumothorax. Immunohistochemistry analysis of the cells obtained from the study confirmed the pleural invasion of the angiosarcoma.

RESUMO

SCOPE: The incidence of cancer is significantly lower in regions where turmeric is heavily consumed. Whether lower cancer incidence is due to turmeric was investigated by examining its effects on tumor cell proliferation, on pro-inflammatory transcription factors NF-κB and STAT3, and on associated gene products. METHODS AND RESULTS: Cell proliferation and cell cytotoxicity were measured by the MTT method, NF-κB activity by EMSA, protein expression by Western blot analysis, ROS generation by FACS analysis, and osteoclastogenesis by TRAP assay. Turmeric inhibited NF-κB activation and down-regulated NF-κB-regulated gene products linked to survival (Bcl-2, cFLIP, XIAP, and cIAP1), proliferation (cyclin D1 and c-Myc), and metastasis (CXCR4) of cancer cells. The spice suppressed the activation of STAT3, and induced the death receptors (DR)4 and DR5. Turmeric enhanced the production of ROS, and suppressed the growth of tumor cell lines. Furthermore, turmeric sensitized the tumor cells to chemotherapeutic agents capecitabine and taxol. Turmeric was found to be more potent than pure curcumin for cell growth inhibition. Turmeric also inhibited NF-κB activation induced by RANKL that correlated with the suppression of osteoclastogenesis. CONCLUSION: Our results indicate that turmeric can effectively block the proliferation of tumor cells through the suppression of NF-κB and STAT3 pathways.

RESUMO

OBJECT: This single-institution Phase II study tests the efficacy of adjuvant radioimmunotherapy with (125)I-labeled anti-epidermal growth factor receptor 425 murine monoclonal antibody ((125)I-mAb 425) in patients with newly diagnosed glioblastoma multiforme (GBM). METHODS: A total of 192 patients with GBM were treated with (125)I-mAb 425 over a course of 3 weekly intravenous injections of 1.8 GBq following surgery and radiation therapy. The primary end point was overall survival, and the secondary end point was toxicity. Additional subgroup analyses were performed comparing treatment with (125)I-mAb 425 (RIT, 132 patients), (125)I-mAb 425 and temozolomide (TMZ+RIT, 60 patients), and a historical control group (CTL, 81 patients). RESULTS: The median age was 53 years (range 19-78 years), and the median Karnofsky Performance Scale score was 80 (range 60-100). The percentage of patients who underwent debulking surgery was 77.6% and that of those receiving temozolomide was 31.3%. The overall median survival was 15.7 months (95% CI 13.6-17.8 months). The 1- and 2-year survivals were 62.5 and 25.5%, respectively. For subgroups RIT and TMZ+RIT, the median survivals were 14.5 and 20.2 months, respectively. No Grade 3 or 4 toxicity was seen with the administration of (125)I-mAb 425. The CTL patients lacked Karnofsky Performance Scale scores, had poorer survival, were older, and were less likely to receive radiation therapy. On multivariate analysis, the hazard ratios for RIT versus CTL, TMZ+RIT versus CTL, and TMZ+RIT versus RIT were 0.49 (p < 0.001), 0.30 (p < 0.001), and 0.62 (p = 0.008), respectively. CONCLUSIONS: In this large Phase II study of 192 patients with GBM treated with anti-epidermal growth factor receptor (125)I-mAb 425 radioimmunotherapy, survival was 15.7 months, and treatment was safe and well tolerated.

RESUMO

BACKGROUND: Investigating atherosclerosis of the coronary artery in ischemic stroke patients is clinically important because comorbidity is relatively common in such patients. We studied the relationship of atherosclerosis of the coronary artery to atherosclerosis of the intracranial cerebral artery and extracranial carotid artery. Further investigation was performed for determining the factors independently associated with coronary artery atherosclerosis in ischemic stroke patients. METHODS: We consecutively recruited ischemic stroke patients who had no history of coronary artery disease, and they underwent vascular examination. Patient-based vascular assessment was performed with magnetic resonance angiography of the cerebral arteries and computed tomography coronary angiography. The factors independently associated with coronary artery stenosis (> or =50%) were obtained from the conventional vascular risk factors and cerebral arterial stenosis using the logistic regression model. RESULTS: Coronary artery stenosis was observed in 25.4% of the patients and this was associated with age (OR: 1.16, 95% CI: 1.03-1.30) and the presence of stenosis of the extracranial carotid artery (OR: 11.37, 95% CI: 1.88-68.75) after logistic regression analysis. Intracranial arterial stenosis was not independently related to coronary stenosis. CONCLUSION: Careful concern about coronary artery disease is needed when treating ischemic stroke patients who have atherosclerosis of the extracranial carotid artery.

RESUMO

BACKGROUND AND AIM: A small proportion of chronic hepatitis B patients have persistently detectable serum hepatitis B virus (HBV) DNA despite lamivudine therapy. The incidence and clinical outcomes of patients who persistently have detectable serum HBV-DNA during lamivudine therapy was investigated. METHOD: We enrolled 221 chronic hepatitis B patients who underwent lamivudine therapy for more than 6 months. Among them, 180 were HBeAg positive. Serum HBV-DNA, HBeAg, anti-HBe and alanine aminotransferase (ALT) levels were serially monitored. The study groups were defined, using a hybridization assay, as patients with reductions in serum HBV-DNA below the detectable level (group I) or patients with persistently detectable serum HBV-DNA (group II) during the initial 6 months of lamivudine therapy. RESULTS: The incidence of patients who had persistently detectable HBV-DNA was 7.7%. After the first year, the rates of viral breakthrough, HBeAg loss and serum ALT normalization of group I versus group II were 21% versus 63%, 38% versus 0%, and 71% versus 28%, respectively (P < 0.001). The log(10) reduction of serum HBV-DNA at 6 months was -4.58 log(10) for group I and -1.97 log(10) for group II (P < 0.001, bDNA assay). There were no pretreatment lamivudine-resistant mutants in group II. CONCLUSION: Lamivudine had little effect on serum HBV-DNA suppression, viral breakthrough suppression and rate of HBeAg loss and ALT normalization in chronic hepatitis B patients with persistently detectable serum HBV-DNA during the initial 6 months of therapy. Early termination of lamivudine therapy is advocated for these patients.
