In this paper, we reported a case of congenital aplasia of dorsal pancreas. This case in 35th case in Japan. The case is 72-year-old male. He feels general fatigability as chief complaint and was taken Diabetes Mellitus. In ERP examination, it was found a short main pancreatic duct of about 4.5 cm length and defect of pancreatic body and tail in Ultrasonogram and Computed Tomogram. In arteriography, it was not found feeding artery to pancreatic body and tail. Accordingly, we diagnosed this case as congenital defect of pancreatic body and tail. This one was normal range for P. F. D. andnormal exocrine pancreatic function. But, this one was operated because of taking cholecystolithiasis. On Retroperitoneal space that shoud be originally pancreatic body and tail, we confirmed only fat tissue without inflammation, fibrosis and carcinomatous tissue. We could not be confirmed Langerhans islet and pancreatic tissue in the biopsy sections of fat tissue.

In Oita prefecture, where ATL is relatively endemic, the authors carried out hematology analysis using an E-4000 hematology analyzer in a health examination. This analysis screened a group of 104 males and 181 females out of randomly collected 11, 568 persons in terms of a higher (exceeded 50%) W-SCR rate (i. e. lymphocyte rate in cell size distribution). The collected peripheral blood smears from this group were further subjected to the examination of lymphocyte morphology.
Abnormal lymphocytes exhibiting dyscaryosis, such as indentation or lobulation, were observed in 11 cases, and further examination of anti-ATLA antibody and earlobe blood smears revealed eight suspected cases of ATL-related condition.
Clinical symptoms characteristic of ATL were not observed in the above eight cases, though the anti-ATLA antibody titer measured by the ELISA method increased by more than 25. In one case, being diagnosed as chronic-type ATL, abnormal lymphocytes amounted to 70% and the leukocyte count was 28, 000/μl. In the other seven cases, abnormal lymphocytes amounted to only 1-11%, and the leukocyte counts ranged from 5, 300 to 11, 100/μl, which was almost within the normal limits.
The method in reported as an useful means for screening cases of nonsymptomatic chronic or smoldering type ATL through a health examination.

Purpose:
Dental floss clip (DFC) traction-assisted endoscopic submucosal dissection (ESD) is widely performed owing to its simplicity. This study aimed to clarify the appropriate indications for the DFC traction method in early gastric cancer when ESD is performed by less-experienced endoscopists.
Methods:
and Methods: We retrospectively analyzed 1,014 consecutive patients who had undergone gastric ESD performed by less-experienced endoscopists between January 2015 and December 2020. Gastric ESD was performed without DFC in all cases before December 2017 [DFC (−) group, 376 cases], and ESD was performed with DFC in all cases after January 2018 [DFC (+) group, 436 cases]. The procedure time and rates of en bloc resection, complete resection, and adverse events of the groups were compared.
Results:
The procedure time did not differ significantly between the 2 groups. However, when comparing lesions >20 mm, the procedure time in the DFC (+) group was significantly shorter than that in the DFC (−) group (95±46 vs. 75±31, P<0.01). The procedure time for lesions located in the greater curvature of the upper or middle stomach and lesions >20 mm located in the lesser curvature side of the stomach in the DFC (+) group was significantly shorter than that in the DFC (−) group.
Conclusions
The indications for DFC during gastric ESD by less-experienced endoscopists include lesions located in the greater curvature of the upper or middle stomach, and lesions >20 mm located in the lesser curvature of the stomach.

The patient was a 68-year-old man. In January 2017, he underwent aortic valve replacement (Carpentier-Edwards Perimount Magna, 25 mm, Edwards Lifescience Corporation, Irvine, USA) for aortic stenosis and coronary bypass surgery with two saphenous vein grafts (SVG-#7 and SVG-4PD) for asymptomatic myocardial ischemia. He was treated as an outpatient by a local physician for at least a week during November 2017, with a principal complaint of mild fever, but no other significant symptoms. Transthoracic echocardiography suggested prosthetic valve endocarditis, so he was referred to the author's hospital. The day after admission, he had symptoms of thoracic discomfort, and emergency cardiac catheter examination showed a lesion thought to be due to a thrombus in the left main coronary trunk ; so, thrombus aspiration was carried out. However, no improvement in blood flow was achieved, so balloon angioplasty was carried out, with the aim of improving blood flow in the left circumflex artery, where coronary artery bypass grafting had not been performed. Improvement in blood flow was achieved, and a culture was carried out using the aspirated thrombus. Streptococcus pasteurianus was detected in the culture.

Neurons migrate from their birthplaces to the destinations, and extending axons navigate to their synaptic targets by sensing various extracellular cues in spatiotemporally controlled manners. These evolutionally conserved guidance cues and their receptors regulate multiple aspects of neural development to establish the highly complex nervous system by mediating both short- and long-range cell-cell communications. Neuronal guidance genes (encoding cues, receptors, or downstream signal transducers) are critical not only for development of the nervous system but also for synaptic maintenance, remodeling, and function in the adult brain. One emerging theme is the combinatorial and complementary functions of relatively limited classes of neuronal guidance genes in multiple processes, including neuronal migration, axonal guidance, synaptogenesis, and circuit formation. Importantly, neuronal guidance genes also regulate cell migration and cell-cell communications outside the nervous system. We are just beginning to understand how cells integrate multiple guidance and adhesion signaling inputs to determine overall cellular/subcellular behavior and how aberrant guidance signaling in various cell types contributes to diverse human diseases, ranging from developmental, neuropsychiatric, and neurodegenerative disorders to cancer metastasis. We review classic studies and recent advances in understanding signaling mechanisms of the guidance genes as well as their roles in human diseases. Furthermore, we discuss the remaining challenges and therapeutic potentials of modulating neuronal guidance pathways in neural repair.
