Introduction: Lipid emulsion preparations, known for their clinical utility, are associated with various adverse events related to lipid metabolism. In this study, we analyzed the safety profile of lipid emulsions in clinical practice, using a real-world database. Methods: The US Food and Drug Administration Adverse Event Reporting System database was used to retrieve adverse events associated with lipid emulsion use. The risk of adverse events was evaluated based on the reported odds ratio and time-to-onset analysis. Results: A total of 4,430 relevant adverse event reports were identified. Hepatic dysfunction tended to occur in the early stages after administration, regardless of the lipid emulsion type. The incidence of hepatic dysfunction varies depending on the triglyceride content of the administered lipid emulsion. Infection tended to occur in the early stages of lipid emulsion administration; however, the incidence did not significantly differ depending on triglyceride content. Conclusion: Our study revealed adverse lipid emulsion events, indicating the need for comprehensive safety management, particularly in the early stages, for clinical use. Particularly, patients receiving parenteral nutrition, irrespective of lipid emulsion administration, necessitate thorough monitoring of liver function and triglyceride levels and reassessment of infusion rates.

Abstract: A 54‐year‐old female patient was hospitalized with a chief complaint of anal discomfort. Based on biopsy results, she was diagnosed with highly differentiated adenocarcinoma, and colonoscopy findings indicated a type 3 rectal tumor. We observed a right pelvic kidney on enhanced abdominal CT. We began a laparoscopic operation but converted to an open operation after resecting the right pelvic renal artery by mistake. After low anterior resection, urologists performed angioplasty of the right renal pelvic artery. The patient was discharged on postoperative day 16, after the preservation of right renal function had been confirmed. This case strongly suggests that it is important to understand the positional relationship of the inferior mesenteric and renal arteries by preoperative assessment using either 3‐D CT angiography or magnetic resonance angiography.

The electron mobilities, μ[sub e], and electron-ion recombination rate constants, k[sub r], in dense gaseous Ar and Kr with a small amount of N[sub 2] or CH[sub 4] as a molecular impurity have been measured as a function of electric field strength using a pulse radiolysis dc-conductivity method combined with a new decay-curve analysis method in which a space-charge effect is taken into account to obtain more accurate values of k[sub r]. The energy of electrons in recombination is controlled experimentally in two ways; one is heating-up by the electric field and the other is cooling-down by inelastic collisions with additive molecules. A large deviation of k[sub r] from the Debye theory obtained in the present experiment has been discussed in terms of the electron mean free paths and electron energies based on recent theories. © 2001 American Institute of Physics.

A 68-year-old woman with a chief complaint of obstructive jaundice was referred to our hospital. She was diagnosed with gallbladder cancer with invasion to the liver, extrahepatic bile duct, right hepatic artery and portal vein. After endoscopic retrograde biliary drainage, she received chemotherapy with gemcitabine and cisplatin. After 9 courses, the size of the tumor and the lymph nodes decreased, and we planned surgery. There were no unresectable factors, and the right hepatic artery and portal vein were detached from the tumor. We performed a subtotal stomach-preserving pancreaticoduodenectomy and gallbladder bed resection. We then performed adjuvant chemotherapy with S-1 for 1 year. The patient remains alive without recurrence, 5 years after the surgery. We report the case of advanced gallbladder cancer with downstaging after GC therapy.

We report a case of human epidermal growth factor receptor 2 (HER2) -positive advanced gastric cancer effectively treated via capecitabine, cisplatin, and trastuzumab (XPT) chemotherapy followed by curative gastrectomy. The patient was a 66- year-old man with type 2 gastric cancer in the greater curvature of the gastric angle. Biopsy revealed that the tumor was a well or moderately differentiated adenocarcinoma, and immunohistochemistry showed positive expression of HER2(3+). Chest and abdominal computed tomography(CT)showed a liver tumor 21×9 mm in size in the caudate lobe and swollen lymph nodes in the paragastric, para-aortic, and left supraclavicular regions. After 4 courses of XPT, a clinical complete response was obtained. The patient received additional 13 courses of trastuzumab and capecitabine and underwent Billroth I distal gastrectomy with D2 lymph node dissection and resection of the para-aortic and left supraclavicular lymph nodes. Liver metastasis was not detected. No residual cancer cells were found in the stomach or lymph nodes except for the left supraclavicular lymph nodes. Pathological classification according to the Japanese Classification of Gastric Carcinoma, 14 th edition, was ypT0, ypN0, ypM1(LYM), Grade 2, ypStage IV. The patient developed a post-operative anastomotic leakage that required drainage via laparotomy, but was discharged 76 days after surgery in good condition.

A 75-year-old man was diagnosed as gall bladder carcinoma by postoperative histological examination following laparoscopic cholecystectomy. He underwent the second surgery of resection of liver bed and port sites with lymph node dissection. Isolated hepatic metastasis of 20 mm in diameter was found in S4/8 by MRI 18 months postoperatively, and stereotactic radiotherapy (52.8 Gy/4 Fr) was done for the metastatic lesion. The lesion could not be detected by CT 7 months after the radiotherapy, and thereafter no local recurrence has been observed for 24 months. However, lymph node metastasis of #9 was diagnosed 31 months postoperatively. Liniac radiotherapy (60 Gy/20 Fr)was performed and stable disease has been obtained for 9 months. The patient is alive at present of 43 months after surgery without any other site of the disease, and his quality of life is well maintained. Stereotactic radiotherapy showed an excellent local therapeutic effect without any serious complications, suggesting that this is a potent modality for isolated liver metastasis of gall bladder carcinoma.
