A 21-hour education program for fifth-year medical students in terminal care was started at Kyushu University in 1991 with the participation of more than 20 lecturers from different specialties. Problems encountered as this curriculum was introduced are discussed. We believe that establishing a professorship in terminal care is essential for improving this curriculum.

With a view to weighing the clinical significance of asymptomatic cerebral infarction, we analyzed the usefulness of the fluid attenuated inversion recovery method in magnetic resonance imaging. The subjects wee composed of 94 outpatients who participated in our screening program for brain troubles. Indications of asymptomatic cerebral infarction were registered on T2-weighted images of 21 subjects (22%) and on FLAIR images of 31 subjects (33%). The FLAIR method, in which the signals from the cerebrospinal fluid are checked, excelled at detecting lesions, especially those under the cerebral cortex which are almost indistinguishable from gray matter and sulci. The subjects with asymptomatic cerebral infarction had significantly many risk factors for stroke including hypertension and hyperlipidemia. Thus, we concluded that the FLAIR method is very useful in diagnosing asymptomatic cerebral infarction.

The purpose of this study was to examine the effects of off-season training on the anaerobic power output and muscle thickness of male varsity rowers. 23 rowers participated in this study. Four all-out cycle ergometer work tests lasting 7 and 40 seconds were used to estimate anaerobic alactic power (AAP) and anaerobic lactic power (ALP) with leg (pedaling) and arm (cranking) exercises. AAP was computed as the highest power output during 7 seconds and ALP was obtained as the mean power output during 40 seconds. Muscle thickness was measured by B-mode ultrasonography at 11 sites on the body. There were significant differences between before and after off-season training in AAP (cranking : 8.4±1.00 vs 9.2±1.10W /kg, p<0.001, pedaling: 14.4± 1.10 vs 15.0±1.00 W/kg, p<0.001) and ALP (cranking : 5.2±0.42 vs 5.5±1.20W/kg, p<0.001, pedaling: 10.1±0.62 vs 9.5±2.10 W/kg, n, s.) . Muscle thickness increased significantly as a result of off-season training at sites on the biceps, triceps, pectoralis major, subscaplar and hamstrings. Similarly, there were significant differences in estimated muscle cross-sectional area (MCSA) on sites on the elbow flexor (20.6±2.6 vs 22.1±1.8cm², p< 0.01), elbow extensor (25.3 ±4.8 vs 28.6±4.2cm², p<0.001) and knee flexor (71.1±5.8 vs 74.3±5.2cm², p<0.01) . The main training program in the off-season consisted of resistance training of the whole body. The high intensity training, used by male varsity rowers during off-season training, increased arm AAP, leg AAP, arm ALP and muscle thickness of the upper body ; but there was no difference in leg ALP and knee extensor muscle. It was suggested that improvements in leg ALP and knee extensor muscle are necessary to during the off-season training program of male varsity rowers.

A 68-year-old woman with a diagnosis of atrial septal defect (ASD) presented with dyspnea. Chest radiography demonstrated cardiomegaly and infiltration in both lungs, suggestive of cardiac decompensation due to ASD. Detailed evaluation with transthoracic echocardiography revealed a mobile tumor on the aortic valve. Intraoperatively, tumors were identified on all aortic cusps. Preservation of the aortic valve was difficult. We therefore performed aortic valve replacement and patch closure of the ASD. The existing literature suggests that mobile papillary fibroelastoma should be excised irrespective of size, to prevent the risk of embolism. Excision of the tumor alone is usually sufficient. However, the present case showed clustered tumors on the aortic valve, so preservation of the cusps could not be achieved in this case.

A case of combined redo off-pump CABG (OPCAB) with right gastroepiploic artery and abdominal aortic aneurysm repair is reported. A 71-year-old man with a previous history of CABG was admitted for the operation of recurrent angina pectoris and known abdominal aortic aneurysm. Preoperative coronary angiograms showed obstruction of LITA graft for LAD. The operative procedure consisted of redo OPCAB using right gastroepiploic artery as a transdiaphragmatic graft under left antero-lateral thoracotomy and graft replacement of abdominal aortic aneurysm under median laparotomy simultaneously. This strategy has the advantage of avoiding the continuity of median sternotomy and laparotomy and contributes to the minimally invasive procedure in the combined operation.

To evaluate a comparison for endovascular repair (EVAR) versus open repair (OR) for the treatment of abdominal aortic aneurysm (AAA). Data of all patients with infrarenal AAA treated electively, both with OR (107 cases) and EVAR (24 cases), at our institute between January 1999 and March 2004 were retrospectively reviewed. No difference was found between the 2 groups for sex, age, and AAA size. Cases of chronic obstructive pulmonary disease (20.8% vs 6.5%, p<0.04) and frequencies of laparotomy (25% vs 2.8%, p<0.001) were significantly more in the EVAR group than the OR group. In the initial results, deployment of the stent grafts was successful in all cases and complete thrombosis of the aneurysm was achieved in 21 cases (87.5%). One graft occlusion and a wound infection occurred in the EVAR group. OR was successfully performed in all cases. These were 6 cases of paralytic ileus, 1 of re-operation for hemorrhage, 1 of respiratory failure, and 1 of ischemic colitis in the OR group. One hospital death occurred in each group. Mean blood transfusion (0ml vs 238±345ml) and operation time (131±53min vs 250±76min) were significantly less in the EVAR group than the OR group. In the long term results, the cumulative survival rate was 88.0±6.5% at 1 and 2 years, 80.6±9.2% at 3 years in the EVAR group; 99.0±0.9% at 1 year, 94.1±2.6% at 2 years, 87.7±3.9% at 3 years in the OR group, with no difference between the 2 groups regarding survival rate. Four new endoleak and 3 graft infections were encountered in the EVAR group. Freedom from stent graft-related complications was 81.3±8.5% at 1 year, 61.4±11.9% at 2 years, 47.8±12.6% at 3 years in the EVAR group, but 100% at 1, 2 and 3 years in the OR group. Freedom from procedure-related complications in the EVAR group was significantly lower than that in OR group. In the long term results, EVAR was associated with more procedure-related complications. This finding may justify reappraisal of currently accepted EVAR for AAA management strategies.

　　Capnocytophaga canimorsus is a spindle-shaped facultatively anaerobic Gram-negative rod in the oral cavity of dogs and cats. C. canimorsus rarely infects humans through an animal bite or scratch. However, it leads to severe sepsis once infection occurs, and the fatality rate is estimated to be up to 30%. The patient was a 56-year-old man with fatigue and fever. Sepsis with thrombocytopenia was suspected from the blood examination results. We decided to conduct microscopic examination of a non-stained peripheral blood smear and identified bacteria; therefore, Gram stain was immediately performed and spindle-shaped Gram-negative bacilli were detected. Additionally, the patient had a history of a bite and scratch by his cat. We suspected C. canimorsus infection from the microscopic examination findings and history. Moreover, we determined early that the pathogenic bacterium was C. canimorsus by blood culture. With immediate and proper treatment based on these results, we could rescue this septic patient with disseminated intravascular coagulation. Microscopic examination of non-stained peripheral blood smear is helpful for the early diagnosis of C. canimorsus infection.

BACKGROUND: The canonical Wnt/β-catenin signaling pathway is a fundamental regulatory system involved in various biological events. ICG-001 selectively blocks the interaction of β-catenin with its transcriptional co-activator cyclic AMP response element-binding protein (CBP). Recent studies have provided convincing evidence of the inhibitory effects of ICG-001 on Wnt-driven disease models, such as organ fibrosis, cancer, acute lymphoblastic leukemia, and asthma. However, the effects of ICG-001 in atopic dermatitis (AD) have not been investigated. OBJECTIVE: To investigate whether β-catenin/CBP-dependent signaling was contributed in the pathogenesis of AD and ICG-001 could be a therapeutic agent for AD. METHODS: We examined the effects of ICG-001 in an AD-like murine model generated by repeated topical application of the hapten, oxazolone (Ox). ICG-001 or vehicle alone was injected intraperitoneally every day during the development of AD-like dermatitis arising from once-daily Ox treatment. RESULTS: Ox-induced AD-like dermatitis characterized by increases in transepidermal water loss, epidermal thickness, dermal thickness accompanied by increased myofibroblast and mast cell counts, and serum levels of thymic stromal lymphopoietin and thymus and activation-regulated chemokine, and decreases in stratum corneum hydration, were virtually normalized by the treatment with ICG-001. Elevated serum levels of periostin tended to be downregulated, without statistical significance. CONCLUSION: These results suggest that β-catenin/CBP-dependent signaling might be involved in the pathogenesis of AD and could be a therapeutic target.

Objective: Human papillomavirus subtypes are predictive indicators of cervical intraepithelial neoplasia (CIN) progression. While colposcopy is also an essential part of cervical cancer prevention, its accuracy and reproducibility are limited because of subjective evaluation. This study aimed to develop an artificial intelligence (AI) algorithm that can accurately detect the optimal lesion associated with prognosis using colposcopic images of CIN2 patients by utilizing objective AI diagnosis. Methods: We identified colposcopic findings associated with the prognosis of patients with CIN2. We developed a convolutional neural network that can automatically detect the rate of high-grade lesions in the uterovaginal area in 12 segments. We finally evaluated the detection accuracy of our AI algorithm compared with the scores by multiple gynecologic oncologists. Results: High-grade lesion occupancy in the uterovaginal area detected by senior colposcopists was significantly correlated with the prognosis of patients with CIN2. The detection rate for high-grade lesions in 12 segments of the uterovaginal area by the AI system was 62.1% for recall, and the overall correct response rate was 89.7%. Moreover, the percentage of high-grade lesions detected by the AI system was significantly correlated with the rate detected by multiple gynecologic senior oncologists (r=0.61). Conclusion Our novel AI algorithm can accurately determine high-grade lesions associated with prognosis on colposcopic images, and these results provide an insight into the additional utility of colposcopy for the management of patients with CIN2.

Objective: In Japan, perioperative prophylaxis of pulmonary embolism (PE) in gynecologic cancer patients with preoperative asymptomatic venous thromboembolism (VTE) has not been well established yet. The GOTIC-VTE trial was a prospective, multi-center, single-arm clinical trial to investigate the prevention of postoperative symptomatic PE onset by seamless anticoagulant therapy from the preoperative period to 4 weeks after surgery instead of using intermittent pneumatic compression. Methods: Anticoagulant therapy was started immediately after asymptomatic VTE diagnosis and stopped preoperatively according to the rules of each institution. Unfractionated heparin administration was resumed within 12 hours postoperatively, and this was followed by the switch to low-molecular-weight heparin and subsequently, edoxaban; this cycle was continued for 28 days. Primary outcome was the occurrence of symptomatic PE in 28 days postoperatively. Secondary outcomes were the incidence of VTE-related events in 28 days and 6 months postoperatively and protocol-related adverse events. Results: Between February 2018 and September 2020, 99 patients were enrolled; of these, 82patients were assessed as the full analysis set, including 58 for ovarian cancer, fallopian tube, or peritoneal cancer; 21 for endometrial cancer; and 3 for cervical cancer. No symptomatic PE was observed within 28 days postoperatively; two patients had bleeding events (major bleeding and clinically relevant nonmajor bleeding) and three had grade 3 adverse events (increased alanine transaminase, aspartate aminotransferase, or gamma-glutamyl transferase). Conclusion The multifaceted perioperative management for gynecologic malignancies with asymptomatic VTE effectively prevented postoperative symptomatic PE.Trial Registration: JRCT Identifier: jRCTs031180124
