ABSTRACT
Objective: IgG4-related sclerosing cholecystitis is generally associated with IgG4-related sclerosing cholangitis and presents with diffuse, circumferential thickening of the gallbladder wall. We report a rare case of localized IgG4-related sclerosing cholecystitis without IgG4-related sclerosing cholangitis, which was difficult to differentiate from gallbladder cancer preoperatively.Patient: A 56-year-old man with suspected IgG4-related disease or gallbladder cancer was admitted to our ward. The serum IgG4 level was elevated at 721 mg/dL. Computed tomography (CT) demonstrated focal wall thickening of the gallbladder fundus. Drip infusion cholecystocholangiography with CT revealed no dilation, stenosis, or border irregularity of the bile duct.Results: For diagnostic and treatment purposes, cholecystectomy with wedge resection of the gallbladder bed was performed. The pathological diagnosis was IgG4-related sclerosing cholecystitis.Conclusion: It is difficult to differentiate IgG4-related sclerosing cholecystitis from gallbladder cancer in cases involving localized thickening of the gallbladder wall. In similar cases, surgical resection with cancer in mind might be performed based on present clinical knowledge.
ABSTRACT
Safe introduction of laparoscopic partial liver resection (LPLR) requires the selection of appropriate cases not exceeding the surgeon's skills as well as standardization of surgical procedures. After introduction at our institution, 60 LPLR procedures were performed between April 2010 and May 2016. To identify indices for case selection, short-term perioperative parameters were analyzed, including operative time, blood loss, postoperative complications, and postoperative hospital stay. Operative time was significantly shorter in the last 30 cases compared with the first 30 cases (182.5 min vs. 253 min; p＝0.023) and in 16 cases involving the left lobe (S2-4) compared with 44 cases involving the right lobe (S1, S5-8; 148.5 min vs. 246 min; p＝0.004). Blood loss was significantly less (0 mL vs. 50 mL; p＝0.028) and operative time was significantly shorter (185 min vs. 250 min; p＝0.048) in 27 cases with tumor diameter ＜2.5 cm compared with 33 cases with tumor diameter ≥ 2.5 cm. Operative time tended to be longer in 9 cases of multiple-site resection compared with 51 cases of single-site resection (207 min vs. 260 min; p＝0.085). BMI, pathology, and hepatitis virus status showed no significant difference in perioperative short-term results. For the introduction of LPLR, it may be preferable to select cases located in the left lobe with a tumor diameter ＜2.5 cm and to accumulate a certain amount of experience in similar cases first.
ABSTRACT
Primary penile melanomas are rare tumors that represent less than 0.1% of all melanomas. We report a case of a 60-year-old Japanese male with a mucosal penile melanoma and describe an increased CD8⁺ T cell infiltration in brain after dacarbazine (DTIC) administration. After partial penectomy and left inguinal lymphadenectomy, he developed multiple lung, bone, spleen, brain and skin metastases. He was treated with interferon-β, DTIC and nivolumab. However, the metastases were not reduced in size. Immunohistochemistry showed an increase of CD8⁺ T cell infiltration and programmed death-ligand 1 (PD-L1) expression after the administration of DTIC, but the expression of programmed cell death protein 1 (PD-1) was negative. We speculate that DTIC exerted immunostimulatory effects, but nivolumab was ineffective due to the negative expression of PD-1 and/or an insufficient infiltration of CD8⁺ T cells. Although this is only one case, this case report could be the first step to discuss the development of effective therapies against melanoma to take advantage of the increased CD8⁺ T cell infiltration elicited by chemotherapeutic agents. It would be beneficial to pay more attention to the relationship between DTIC and immune checkpoint modulators.

We conducted a survey to measure the change of awareness about Kampo medicine following through four lectures of educational interventions delivered to the third-year students in a national registered dietitian training program. Awareness with regard to Kampo medicine was surveyed before and immediately after the interventions. We also collected the same questionnaire again five months after the interventions. The students' scores changed significantly between before and immediately after the interventions in the favorable direction regarding their interest in Kampo medicine, the necessity of including Kampo medicine in future educational programs, and the potential usefulness of Kampo medicine at their future workplaces, and the changes were maintained for five months.<BR>About 70% of students answered that they became more familiar with Kampo medicine as a result of the classes, but their knowledge of Kampo medicine was poor before the lectures and even immediately after the interventions. These results suggest that education about Kampo medicine for students in a national registered dietitian training program is important, because it could be a positive incentive for them to learn about Kampo medicines and herbs and to accept the use of Kampo medicine at their future workplaces.
ABSTRACT
Background and objective : Diet has been recognized as an important part of Kampo medicine, and various plants with which we often cook are included as components of many Kampo formulations. Accordingly, nutritional science is closely related to Kampo medicine. So there is a need for national registered dietitian and nutritional science students to learn Kampo medicine. Despite this, no survey has reported on the awareness of nutritional science students toward Kampo medicine in Japan. We conducted for the first time a survey on this awareness amongst nutritional science students about Kampo medicine.Methods : A 13-item anonymous questionnaire was distributed to the third-year students in a national registered dietitian training program in Japan.Results : We obtained answers from 509 students in 9 institutions. Of the respondents, 59.3% answered that they were interested in Kampo medicine, and 86.4% of the students who were not interested in Kampo medicine answered that the reason was they had no chance to learn it. However, 81.3% of the students answered that they would attend lectures on Kampo medicine if it was adopted as part of their curriculum.Conclusions : These results suggest that Kampo medicine should be included in educational programs for nutritional science students.
