Although renal artery stenosis and pheochromocytoma are well-known causes of HTN in NF1, this case demonstrates that HTN can be caused by AUK in patients with NF1.A 71-year-old woman was hospitalized for the treatment of fatigue, fever, and cough. On admission, she showed increased serum inflammation markers, severe anemia, pulmonary hemorrhage, and advanced acute kidney injury requiring hemodialysis. Her serum anti-glomerular basement membrane (GBM) antibody titer was found to be extremely high on the 7th hospital day. She was eventually diagnosed with anti-GBM disease. She was treated with a combination of corticosteroid pulse therapy, oral prednisolone and cyclophosphamide, and plasma exchange, but continued to require maintenance hemodialysis for end-stage kidney disease. During her treatment, she suddenly developed headache, blindness, seizure, and consciousness disturbance. She was diagnosed by magnetic resonance imaging with posterior reversible encephalopathy syndrome (PRES) with subcortical cerebral hemorrhage. Both the PRES and cerebral hemorrhage subsided soon after control of her hypertension and reinforcement of immunosuppressive treatment. PRES, particularly when accompanied by cerebral hemorrhage, may cause irreversible and lethal neurological abnormalities, and nephrologists should, therefore, be aware of the potential risk of PRES in patients with anti-GBM disease. We discuss the current case in the light of the previous literature.BACKGROUND One anastomosis gastric bypass (OAGB) is gaining wide spread acceptance among bariatric surgeons all over the world because of its technical simplicity and documented efficacy. However, the relation between stoma size in OAGB and magnitude of weight loss has not been addressed. OBJECTIVES To evaluate the effect of stoma size on the mid-term weight loss outcome for patients with obesity after OAGB. SETTING University Hospital. MATERIALS AND METHODS This is a single-blinded prospectively randomized trial. From March 2014 to September 2016, 83 patients, eligible for bariatric surgery, were included in the study. OAGB was carried out with the same technical steps, except for the size of the gastrojejunostomy (GJ). Patients were randomly allocated into two equal groups; narrow GJ group (30 mm) and wide GJ group (45 mm). The percentage of total weight loss (%TWL) and the percentage of excess weight loss (%EWL) were recorded at 6, 12 and 24 months after procedure. RESULTS At 6 months follow-up, patients with 30 mm GJ had better %EWL (53.3) and %TWL (23.4) than other patients with 45 mm GJ (42.6 and 18.2 respectively). However, at 12 and 24 months the %TWL and %EWL difference between the two groups have disappeared. CONCLUSION Patients with narrower stoma size (30 mm) of OAGB tend initially to lose more weight than patients with wider stoma (45 mm). However, this difference disappears at mid-term follow-up after 2 years.BACKGROUND This study aimed to investigate the short- and long-term outcomes of laparoscopic gastrectomy (LG) in patients with advanced gastric cancer following neoadjuvant chemotherapy (NAC) to determine its safety and feasibility. METHODS We retrospectively investigated 51 patients who underwent gastrectomy for locally advanced gastric cancer [cT3-4/N1-3 or macroscopic type 3 (> 80 mm) or type 4] following NAC between November 2009 and January 2018. AZD-5462 price After excluding two patients who underwent palliative surgery due to peritoneal dissemination, 49 patients were ultimately selected for this cohort study. The patients were then divided into the LG group and open gastrectomy (OG) group, after which the clinicopathological characteristics as well as short- and long-term outcomes were examined. RESULTS Compared with the OG group, the LG group demonstrated a significantly lower amount of intraoperative blood loss and a shorter hospital stay. The overall complication rates were 10% (2 of 20 patients) and 24% (7 of 29 patients) in the LG and OG groups (P = 0.277), respectively. No significant differences in 5-year disease-free (LG 44.4% vs. OG 53.3%; P = 0.382) or overall survival rates (LG 46.9% vs. OG 54.0%; P = 0.422) were observed between the groups. Multivariate analysis revealed that the surgical procedure (LG vs. OG) was not an independent risk factor for disease-free (P = 0.645) or overall survival (P = 0.489). CONCLUSIONS LG may be a potential therapeutic option for patients with gastric cancer following NAC considering its high success rates and acceptable short- and long-term outcomes.OBJECTIVE The purpose of this study was to explore the role of different undifferentiated components in the lymph node metastasis (LNM) of early mixed gastric cancer. METHODS A total of 1596 patients with EGC who underwent gastrectomy were divided into four types pure differentiated (PD), pure poorly differentiated (Poorly D), pure signet ring cell carcinoma (SRC), and mixed. Mixed type was classified into four subtypes differentiated-predominant type mixed with poorly differentiated component (MD-P), poorly differentiated-predominant type mixed with differentiated component (MP-D), differentiated-predominant type mixed with SRC component (MD-S), and poorly differentiated-predominant type mixed with SRC component (MP-S). We analyzed the clinicopathological differences between all types and the rates of LNM of patients fulfilling endoscopic submucosal dissection (ESD) criteria. RESULTS LNM was more common in mixed (21.9%) than in PD (7.5%, P  less then  0.001) or SRC (11.3%, P  less then  0.001). When analyzed the subgroups of mixed type, LNM was more frequent in MD-P (15.4%) than in PD (7.5%, P = 0.003). LNM in MD-S (7.4%, P = 1.000) was not higher than in PD. MP-S (24.5%) showed a higher rate of LNM than SRC (11.3%, P  less then  0.001) rather than Poorly-D (22.7%, P = 0.681). For lesions satisfying ESD criteria, MD-S (0%, P = 1.000), and MD-P (5.9%, P = 0.12) did not have higher rates of LNM than PD (1.4%). CONCLUSION The presence of poorly differentiated component but not SRC increases the LNM rate of mixed type. ESD is recommended for the treatment of MD-S and MD-P consistent with ESD criteria.
