Clinical significance of the post/preoperative anti-p53 antibody ratio in predicting the prognosis of patients with colorectal cancer after curative surgery and its usefulness in combination with carcinoembryonic antigen.

[Introduction] Anti-p53 antibody (p53Ab) is useful for monitoring colorectal cancer (CRC) recurrence. We retrospectively analyzed the clinical impact of p53Ab ratio (p53R) before and after surgery to predict recurrence in patients with CRC. [Methods] In total, 1,223 patients with stage I-III CRC who underwent curative surgery between January 2005 and December 2019 were enrolled in this retrospective study. In patients with elevated p53Ab levels, p53R was calculated by measuring p53Ab levels within one month preoperatively and three months postoperatively. The optimal p53R level was determined, and its relationship with clinicopathological factors and prognosis was examined. We also evaluated the efficacy of the combination of p53R and preoperative carcinoembryonic antigen (CEA) values. [Results] Overall, 341 patients (27.9%) showed elevated p53Ab levels. Preoperative p53Ab levels were significantly associated with tumor location, lymphatic invasion, and venous invasion. The p53R level was significantly higher in patients with recurrent disease. Patients with high p53R levels had significantly shorter relapse-free survival (RFS) than those with low p53R levels (p < 0.001). When p53R was combined with preoperative CEA values, specificity improved to 0.97, with an accuracy of 0.88. [Conclusion] In patients with CRC and elevated preoperative p53Ab levels, p53R expression may be prognostically useful after radical resection. Furthermore, the combination of p53R and preoperative CEA levels may be useful for postoperative follow-ups.

Sex Differences in Cardiovascular Disease-Related Hospitalization and Mortality in Japan　- Analysis of Health Records From a Nationwide Claim-Based Database, the Japanese Registry of All Cardiac and Vascular Disease (JROAD).

BACKGROUND: The prevalence of cardiovascular disease (CVD) is rising in Japan with its aging population, but there is a lack of epidemiological data on sex differences in CVD, including acute coronary syndrome (ACS), acute heart failure (AHF), and acute aortic disease.Methods and Results: This retrospective study analyzed data from 1,349,017 patients (January 2012-December 2020) using the Japanese Registry Of All Cardiac and Vascular Diseases database. ACS patients were youngest on average (70.5±12.9 years) and had the lowest female proportion (28.9%). AHF patients had the oldest mean age (79.7±12.0 years) and the highest proportion of females (48.0%). Acute aortic disease had the highest in-hospital mortality (26.1%), followed by AHF (11.5%) and ACS (8.9%). Sex-based mortality differences were notable in acute aortic disease, with higher male mortality in Stanford Type A acute aortic dissection (AAD) with surgery (males: 14.2% vs. females: 10.4%, P<0.001) and similar rates in Type B AAD (males: 6.2% vs. females: 7.9%, P=0.52). Aging was a universal risk factor for in-hospital mortality. Female sex was a risk factor for ACS and acute aortic disease but not for AHF or Types A and B AAD. CONCLUSIONS: Sex-based disparities in the CVD-related hospitalization and mortality within the Japanese national population have been highlighted for the first time, indicating the importance of sex-specific strategies in the management and understanding of these conditions.

Robotic surgery after total neoadjuvant therapy for rectal cancer: pitfalls of beyond total mesorectal excision for patients with sidewall invasion.

AIM: Total neoadjuvant therapy (TNT) for locally advanced rectal cancer (LARC) is rapidly spreading. The robotic surgical techniques to approach lateral invasion, such as that of the pelvic plexus, have not yet been established. In this technical note, we present a video illustrating a surgical technique for lateral invasion using our novel technique and discuss its pitfalls. METHOD: We present the case of a 65-year-old man with LARC. Robotic surgery was performed after TNT using the da Vinci Xi Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA). The surgical procedure was as follows: (1) D3 lymph node dissection around the inferior mesenteric artery using a medial-to-lateral approach; (2) rectal mobilization; (3) dissection of the ureterohypogastric fascia and ureter; and (4) combined resection of the hypogastric nerve and pelvic plexus. The key surgical point for sidewall invasion is the resection extent. Dividing the resection extent into three areas is important: zone A, which contains the pelvic plexus and is closest to the tumour; zone B, which contains the iliac vessels; and zone C, the most lateral zone, which contains the obturator nerves. This allows organ and function preservation by resecting only the smallest organ that truly requires R0 resection. RESULTS: The operating time was 333 min, console time was 232 min, and blood loss was 0 mL. The circumferential resection margin was 10 mm, and an R0 resection was achieved. CONCLUSION: We introduced a novel approach for robotic surgery after TNT for LARC with sidewall invasion. This technique can be performed safely and may help standardize 'beyond total mesorectal excision'.

C-reactive protein-to-albumin ratio as a risk factor for anastomotic leakage after anterior resection for rectal cancer with intraoperative use of indocyanine green fluorescence imaging.

INTRODUCTION: Indocyanine green fluorescence imaging (ICG-FI) reduces anastomotic leakage (AL) in rectal cancer surgery. However, no studies investigating risk factors for anastomotic leakage specific to the group using ICG-FI have ever previously been conducted. The purpose of this retrospective multicenter study was to ascertain the risk factors for AL in the group using ICG-FI. METHODS: A total of 638 patients who underwent laparoscopic or robotic anterior resection for rectal cancer between April 2018 and March 2023 were included in this study. Patients were divided into two groups: the ICG-FI group (n = 269) and the non-ICG-FI group (n = 369) for comparative analysis. The effects of clinicopathological and treatment-related factors on AL in the ICG-FI group were evaluated using both univariate and multivariate analyses. RESULTS: The incidence of AL in the ICG-FI group was 4.8%. Although there was no significant difference in the incidence of AL between the two groups, it was observed to be lower in the ICG-FI group. A multivariate analysis revealed a preoperative C-reactive protein-to-albumin ratio (CAR) ≥ 0.049 (odds ratio, 3.73; 95% confidence interval, 1.01-13.70; p = 0.048) as an independent risk factor for AL in the ICG-FI group. CONCLUSIONS: In this study, CAR was the only identified risk factor for AL in the ICG-FI group. It was suggested that CAR could be a criterion for early surgical intervention, prior to the escalation of risks, or for considering interventions such as diverting stoma creation.

Influence of proficiency in conventional laparoscopic surgery in colorectal cancer on the introduction of robotic surgery.

PURPOSE: Although there have been many reports on learning curves for robotic surgery, it is unclear how surgeons' conventional laparoscopic surgical skills influence their ability in performing robotic surgery for colorectal cancer (CRC). The aim of this study was to determine the surgical outcomes of robotic surgery for CRC during the induction phase by skilled laparoscopic surgeons. METHODS: Surgical outcomes of consecutive CRC cases between January 2021 and March 2023 following the skilled phase of laparoscopic surgery and introductory phase of robotic surgery performed by three skilled laparoscopic surgeons were compared. RESULTS: Overall, 77 consecutive patients diagnosed with sigmoid colon or rectosigmoid cancer were analysed, including 50 in the laparoscopy group (LAP) and 27 in the robotic group (Ro). Patient characteristics, including age, sex, body mass index, and tumour progression, did not differ between the groups. The median operation time was 204 min in the robotic group and 170 min in the laparoscopic group (p < 0.001). Blood loss was significantly lower in the robotic group (p = 0.0059). The incidence of grade 2 or higher complications did not differ between the two groups (LAP, 10.0% vs. Ro, 7.4%, p = 1). In the robotic group, the time required for lymph node dissection had a greater impact on operative duration. CONCLUSION: Skills acquired from performing conventional laparoscopic surgery may contribute to the safe and reliable performance of robotic surgery for CRC. TRIAL REGISTRATION: UMIN000050923.

Prospective observational study comparing the perioperative outcomes of laparoscopic colectomy with or without epidural anesthesia: the Kanagawa Yokohama Colorectal Cancer Study Group (KYCC) 1806.

PURPOSE: There have been no adequate comparisons of the efficacy, safety, and efficiency of analgesia after laparoscopic colorectal resection (LAC), with and without epidural anesthesia (EDA). METHODS: This was a multicenter prospective observational study of patients undergoing LAC. The primary end point was the mean visual analog scale (VAS) score on postoperative days (PODs) 1-7. The secondary end points were the highest VAS, complication rate, days to first ambulation and fatigue, length of hospital stay, and time to commencement of surgery. RESULTS: We compared an EDA group (Group E, n = 48) and a no-EDA group (Group O, n = 48) after matching. The mean VAS was not significantly different between the groups (28.7 vs. 30.1, p = 0.288). On assessing the secondary end points, the highest VAS was not significantly different between the groups. In fact, the VAS was lower in Group E only on POD 2. There was no difference in the incidence of complications, the time to first postoperative evacuation was shorter in Group E, and postoperative hospitalization was similar. The time to surgery was shorter in Group O. CONCLUSION: These results suggest that LAC without EDA is a feasible option, but with the early and regular use of adjunctive measures to provide more stable analgesia.

Time course changes in insulin sensitivity during cardiac surgery: A retrospective study on intraoperative glycemic management using an artificial pancreas.

INTRODUCTION: Glycemic control is essential for improving the prognosis of cardiac surgery, although precise recommendations have not yet been established. Under a constant blood glucose level, the insulin infusion rate correlates with insulin resistance during glycemic control using an artificial pancreas (AP). We conducted this retrospective study to elucidate changes in intraoperative insulin sensitivity as a first step to creating glycemic control guidelines. METHODS: Fifty-five cardiac surgery patients at our hospital who underwent intraoperative glycemic control using an AP were enrolled. Twenty-three patients undergoing surgical procedures requiring cardiac arrest under hypothermic cardiopulmonary bypass (CPB) with minimum rectal temperatures lower than 32°C, 13 patients undergoing surgical procedures requiring cardiac arrest under hypothermic CPB with minimum rectal temperatures of 32°C, eight patients undergoing on-pump beating coronary artery bypass grafting and 11 patients undergoing off-pump coronary artery bypass were assigned to groups A, B, C and D, respectively. We analyzed the time course of changes in the data derived from glycemic control using the AP. RESULTS: Significant time course changes were observed in groups A and B, but not in groups C and D. Insulin resistance was induced after the start of hypothermic CPB in groups A and B, and the induced change was not resolved by the rewarming procedure, remaining sustained until the end of surgery. CONCLUSIONS: Hypothermia is the predominant factor of the induced insulin resistance during cardiac surgery. Thus, careful glycemic management during hypothermic CPB is important. Prospective clinical studies are required to confirm the findings of this study.

[A Case of Meningeal Carcinomatosis following Esophagogastric Junction Cancer Surgery].

In a 79-year-old man, upper gastrointestinal endoscopy and CT revealed an entire circumferential type 3 tumor with stenosis from the lower thoracic esophagus to the abdominal esophagus. He was diagnosed with esophageal adenocarcinoma and underwent middle and lower esophageal resection and 2 regional lymph node dissections. The postoperative pathological diagnosis was poorly differentiated adenocarcinoma, pT3N0M0, pStage ⅡA esophagogastric junction cancer(Siewert type Ⅱ). The patient was followed-up without postoperative adjuvant chemotherapy, following the Japanese Gastric Cancer Treatment Guidelines 2021(6th edition). Six months postoperatively, contrast-enhanced CT revealed multiple lymph node, small intestinal mesenteric, and left adrenal metastases, and SOX therapy was initiated. After 4 courses of SOX therapy, the patient was brought to the emergency room and admitted with anorexia and weakness, and consciousness disorder was observed on the next day. Contrast-enhanced MRI of the head was indicative of meningeal carcinomatosis, and cytological examination of the spinal fluid revealed adenocarcinoma, which was diagnosed as meningeal carcinomatosis from esophagogastric junction carcinoma. Subsequently, his consciousness disorder worsened, and he died on the 9th day of hospitalization. We report a rare case of meningeal carcinomatosis following esophagogastric junction cancer.

[A Case of Distal Gastrectomy and Left Segmentectomy for Hepatic Invasion of Gastric Cancer].

A 66-year-old male came to our hospital because of occult blood in stool and anemia. The patient was diagnosed as unresectable advanced gastric cancer,( ML/Less, type 2, tub2, cT4b[liver], cN+, cM0, cStage Ⅳ, HER2 negative). He was given oxaliplatin plus S-1 therapy. In the 3rd course of chemotherapy, he had severe anemia, and active bleeding from the tumor. To control the bleeding he underwent distal gastrectomy, lateral segmentectomy of the liver, and S4 partial hepatectomy. The patient underwent adjuvant chemotherapy with docetaxel plus S-1. Three months after surgery, lymph nodes recurrence was observed. He underwent second-line therapy with paclitaxel and ramucirumab. Seven months after surgery, lymph nodes recurrence was increased. He was switched to third-line therapy with nivolumab. He is currently arrive 12 months after surgery.

[A Case of Colon Metastasis after Surgery for Left Renal Pelvis Cancer].

The patient was a 73-year-old man. He was diagnosed with left renal pelvic carcinoma(papillary urothelial carcinoma, pT3aN0M0, Stage Ⅱ)at the age of 69. Left nephroureterectomy and partial cystectomy were performed at our hospital. At the age of 71, he was diagnosed with a recurrent bladder tumor and underwent radical cystectomy and ureteroenterostomy at a different hospital. At the age of 73, he visited our hospital with abdominal pain. Computed tomography(CT)revealed wall thickening of the descending colon and dilation of the oral tract. Emergency colonoscopy was performed. He was diagnosed with intestinal obstruction due to descending colon cancer. Colonoscopy revealed a circumferential type 2 lesion in the descending colon that was completely stenosed. Colonic stent placement was performed. A tumor biopsy confirmed the diagnosis of micropapillary adenocarcinoma. The preoperative diagnosis was descending colon cancer cT4aN2aM0, cStage Ⅲc. One month after stent placement, an open segmental resection of the descending colon with D2 dissection was performed. Immunostaining of the specimen showed CK7(+)and CK20(-), and the postoperative diagnosis was a recurrence of left renal pelvic carcinoma in the descending colon. We report a rare case of renal pelvic carcinoma that recurred in the descending colon 4 years after initial surgery.

Is adjuvant chemotherapy for completely resected p-stage IA (>2 cm) and stage IB non-small-cell lung cancer beneficial for elderly patients? A large, retrospective cohort study based on real-world data from Japan.

OBJECTIVE: The efficacy of tegafur-uracil as adjuvant chemotherapy for patients with completely resected stage I non-small-cell lung cancer is proven; however, its efficacy for elderly patients remains unclear. Herein, we evaluated the effectiveness of adjuvant chemotherapy for elderly patients with completely resected stage I non-small-cell lung cancer based on real-world Japanese data using propensity score matching. METHODS: This retrospective study extracted data from a nationwide registry study, performed in 2016, on patients ≥75 years who underwent lobectomy with mediastinal nodal dissection for non-small-cell lung cancer in 2010 and were diagnosed with p-stage IA (>2 cm) or stage IB non-small-cell lung cancer. We classified the 1294 patients into two groups-Group A, postoperative adjuvant chemotherapy (n = 295, 22.8%) and Group N, no adjuvant chemotherapy (n = 999, 77.2%)-and analyzed differences in postoperative overall survival between groups. RESULTS: Group A showed no advantage in overall survival over Group N as a whole (hazard ratio: 0.824 [95% confidence interval: 0.631-1.076]), in p-stage IA (hazard ratio: 0.617 [95% confidence interval: 0.330-1.156]) and in p-stage IB (hazard ratio: 0.806 [95% confidence interval: 0.597-1.088]) subsets. Even after propensity score matching, Group A showed no significant advantage in overall survival over Group N as a whole (hazard ratio: 0.975 [95% confidence interval: 0.688-1.381]), in p-stage IA (hazard ratio: 1.390 [95% confidence interval: 0.539-3.586]) and in p-stage IB (hazard ratio: 0.922 [95% confidence interval: 0.633-1.343]). CONCLUSIONS: adjuvant chemotherapy for completely resected p-stage IA (>2 cm) and stage IB non-small-cell lung cancer showed no benefit for recommendation for elderly patients; considering the risk of adverse events, we do not recommend adjuvant chemotherapy for elderly patients.

Association between autistic traits and binge drinking: Findings from Japan.

PURPOSE: Substance misuse may be elevated in some individuals with autism spectrum disorder (ASD). As yet, however, little is known about the association between autistic traits (AT) and substance use/misuse in adults. This study examined the association between AT and binge drinking (BD) among individuals in Japan. METHODS: Data were analyzed from 1452 individuals aged 18 and above collected during an online survey in February 2021. Self-reported information was obtained on BD assessed as consuming 5 or more (males) or 4 or more (females) drinks containing any kind of alcohol within a 2-h period. AT were assessed with the Japanese version of the Autism Spectrum Quotient - the AQ-J-10. Logistic regression analysis was used to examine associations. RESULTS: The prevalence of past-month BD was significantly higher in individuals with AT compared to those without AT (42.7% > 27.6%). In a fully adjusted analysis that controlled for mental health (anxiety, depression) and attention-deficit/hyperactivity disorder symptoms, individuals with AT had significantly higher odds for BD once a week or more often (OR: 1.54, 95%CI: 1.04-2.29). AT were also associated with significantly higher odds for BD among women (OR: 2.27, 95%CI: 1.08-4.76), and those aged 18-34 (OR: 2.37, 95%CI: 1.09-5.18) and aged 60 and above (OR: 2.15, 95%CI: 1.02-4.53). CONCLUSION: Individuals with AT have higher odds for BD. Increased efforts to detect alcohol use/misuse in adults with AT and AT in adults misusing alcohol may be efficacious in efforts to manage symptoms and eliminate harmful alcohol misuse.

Effectiveness and safety of Tolvaptan in infants with congenital heart disease.

BACKGROUND: Tolvaptan (TLV) is a selective vasopressin receptor 2 antagonist administered for congestive heart failure (CHF) after inadequate response to other diuretics. The effectiveness and safety of TLV have been evaluated well in adult patients. However, reports on its use in pediatric patients, especially infants, are scarce. METHODS: We retrospectively evaluated 41 children younger than 1 year of age who received TLV for CHF for congenital heart disease (CHD) between January 2010 and August 2021. We monitored the occurrence of adverse events, including acute kidney injury and hypernatremia, as well as laboratory data trends. RESULTS: Of the 41 infants included, 51.2% were male. The median age when TLV was initiated was 2 months, interquartile range (IQR) 1-4 months, and all infants had been administered other diuretics previously. The median dose of TLV was 0.1 mg/kg/day (IQR, 0.1-0.1). Urine output increased significantly after 48 h of treatment: baseline, 315 mL/day (IQR, 243-394); 48 h, 381 mL/day (IQR, 262-518) , p = 0.0004; 72 h, 385 mL/day (IQR, 301-569), p = 0.0013; 96 h, 425 mL/day (IQR, 272-524), p = 0.0006; and 144 h, 396 mL/day (IQR, 305-477), p = 0.0036. No adverse events were observed. CONCLUSIONS: Tolvaptan can be used safely and efficiently in infants with CHD. From the perspective of adverse effects, initiating administration at a lower dosage is preferable because this was found to be sufficiently effective.

[Laparoscopic Low-Anterior Resection for Sigmoid Colon Cancer and Rectosigmoid Adenoma in a Patient with Situs Inversus].

A 63-year-old woman, who were in a nursing house, visited our hospital with complaints of bloody stools and anemia. Some investigations were performed, CS and CT revealed her diagnosis with sigmoid colon cancer(cT3N0M0)and rectosigmoid adenoma with situs inversus(SI). Laparoscopic low-anterior resection was performed. Postoperative course was good without any complications, and she discharged our hospital at the day 7 after the operation. In surgery, we had to be conscious of mirror image and set operative equipment and operative staffs inversely from normal setting. Some previous reports suggested that some surgical process such as cutting and separating with left hand(non-dominant hand), especially at interior separation, were effective in laparoscopic surgery for SI patients. However, in our operation, we used ultrasonic coagulator with short-pitched incision with surgeon's right hand(dominant hand)instead of left-handed process, and it could be useful for laparoscopic surgery for SI patients. In intrapelvic processes, we proceeded with the surgery as usual because of the symmetric structure of intrapelvic organs. We could complete the laparoscopic low-anterior resection for SI patient with several ingenuity for operative processes.

[A Case of Desmoid Fibromatosis of the Small Intestinal Mesentery Institutions].

The patient was a 27-year-old man. He was referred to our hospital because he was aware of a mass in his abdomen. An abdominal ultrasound showed a 70-mm mass lesion. Enhanced computed tomography showed a 70-mm mass with well- defined margins and heterogeneous internal enhancement near the proximal jejunum. The patient was diagnosed with a suspected primary submucosal tumor of the duodenum or small intestine, and surgery was planned to diagnose and treat the tumor. The tumor was located in the upper jejunal mesentery, and tumor resection and partial small bowel resection were performed. Histopathological examination revealed proliferation of spindle-shaped cells without karyomitosis, and mixed collagen fibers in the tissue. Immunohistochemistry showed ß-catenin(+), SMA(+), AE1/AE3(-), KIT(-), CD34(-), and S-100(-). Based on these findings, we diagnosed primary desmoid fibromatosis of the small intestinal mesentery. In this report, we describe a case of primary desmoid fibromatosis of the small intestinal mesentery with a review of the literature.

[A Case of HER2-Positive Advanced Gastric Cancer with Liver Metastasis Treated by Laparoscopic Surgery after Chemotherapy and Achieved Pathological Complete Response].

A 77-year-old man presented to our hospital with diarrhea and weight loss. Upper gastrointestinal endoscopy revealed advanced Type 3 gastric cancer measuring 40 mm in the lower greater curvature of the stomach. Biopsy from a gastric tumor revealed moderately differentiated tubular adenocarcinoma overexpressing HER2. Abdominal contrast-enhanced computed tomography(CT)showed multiple liver metastases in S3 and S5. We diagnosed HER2-positive gastric cancer with liver metastasis. Systemic chemotherapy was administrated, with a total of 13 courses of combination therapy with S-1, oxaliplatin and trastuzumab. After chemotherapy, the primary tumor was significantly reduced and liver metastases were almost undetectable. Laparoscopic distal gastrectomy and partial hepatectomy were performed as conversion surgery. The patient was discharged on the 9th day without any postoperative complications. Postoperative pathological findings showed no residual tumor in either gastric and hepatic specimens, and the therapeutic effect of chemotherapy was diagnosed as pathological complete response. We report a case of HER2-positive advanced gastric cancer with multiple liver metastases that achieved a pathologically complete response to chemotherapy followed by conversion surgery. Laparoscopic surgery would be one of an effective option for conversion surgery.

[Indications and Outcomes of Laparoscopic Endoscopic Cooperative Surgery(LECS)for Gastric Gastrointestinal Stromal Tumor].

Laparoscopic and endoscopic cooperative surgery(LECS)for gastric gastrointestinal stromal tumor(GIST)has become a popular surgery with both curability and functional preservation. In this study, we examined the outcomes of 14 patients who underwent classical LECS or CLEAN-NET in our hospital. Until March 2022, classical LECS was performed in patients with intraluminal growth tumors or tumors close to the gastroesophageal junction. After April 2022, classical LECS was performed in patients with intraluminal growth tumors without ulceration, and CLEAN-NET was performed in patients with ulceration or intramural growth tumors. There were 10 males and 4 females with a median age of 80.5 years. Intraluminal growth tumor were 8 patients, close to the gastroesophageal junction tumor were 3, and intramural growth tumor were 4, respectively. Five of these patients had tumors with ulceration. Classical LECS was performed in 10 patients and CLEAN-NET in 4 patients, and the median operative time was 165.5 minutes. All patients underwent R0 resection, and no postoperative complications or recurrences were observed. LECS was performed safely, and it is important to select the surgical procedure according to the tumor site and growth type.

[A Case of Neuroendocrine Carcinoma of the Extrahepatic Bile Duct].

A 77-year-old man visited a clinic because of nausea and chest discomfort. On blood test, hepatobiliary enzymes were elevated, and he referred to our hospital. Contrast-enhanced CT revealed stenosis of the extrahepatic bile duct and brush cytology of the bile duct showed adenocarcinoma. We therefore performed pancreatoduodenectomy for extrahepatic bile duct cancer. Pathological diagnosis was small cell neuroendocrine carcinoma, pT3N2M0, Stage ⅢA. The patient did not receive adjuvant chemotherapy and 3 months later contrast-enhanced CT and MRI showed multiple liver metastases. The patient was treated with cisplatin plus irinotecan in the first-line, cisplatin plus etoposide in the second-line, and amrubicin in the third-line and accordingly he died 1 year and 3 months after the surgery. Chemotherapy for neuroendocrine carcinoma of the bile duct is recommended as in small cell lung cancer, but the prognosis is extremely poor. We report this case with a review of some of the literature.

[A Case of T-Cell Lymphoma Treated by Emergency Surgery Due to Bleeding of Jejunal Lesion].

A 78-year-old man was aware of lightheadedness and darkness at a routine outpatient visit, and his blood pressure was declined at 87/51 mmHg. Contrast-enhanced CT scan showed an extravascular leakage image at jejunum. We diagnosed as small intestinal hemorrhage. Because he was in hemorrhagic shock, emergency surgery was performed. A tumor was found coincident with the bleeding site, and partial resection of the small intestine including enlarged lymph nodes was performed. Based on the pathological findings of T-cell origin and positive for serum anti-HTLV-1 antibody, he was suspected as adult T-cell leukemia/lymphoma(ATLL). Endoscopic examination of the upper and lower gastrointestinal tracts, bone marrow examination, and PET-CT scan were performed, but no other lesions were found. We report a case of the T-cell lymphoma with suspected solitary ATLL of the jejunum.

Emotional and behavioral problems in Japanese preschool children with subthreshold autistic traits: findings from a community-based sample.

BACKGROUND: Recently, there has been a growing recognition that autistic traits exist along a continuum beyond diagnostic categories and that even subclinical symptoms may be associated with an increased risk for the psychosocial well-being and mental health of children. However, as yet, there has been little research on whether preschool children with autism spectrum disorder (ASD) symptoms, who do not meet the diagnostic criteria for ASD, are more likely to experience difficulties. To address this deficit this study examined whether young children with subthreshold autistic traits have an increased risk for emotional/behavioral difficulties. METHODS: Data were analyzed from 1057 Japanese preschool children aged 5-years old collected during the first wave of the Tama Children's Survey (TCS) cohort study. Parent-reported autistic traits were assessed with the Social Responsiveness Scale (SRS), while they provided information on their child's emotional/behavioral problems using the Strengths and Difficulties Questionnaire (SDQ). Logistic regression analysis was used to examine associations. RESULTS: Preschool children with mild-to-moderate autistic traits, corresponding to subclinical autism were significantly more likely to score above the clinical thresholds for emotional/behavioral problems compared to children with fewer autistic traits. Follow-up diagnostic assessments and analyses of 72 children from the cohort confirmed these findings and showed that these children with subthreshold autistic traits also had a significantly lower intelligence quotient (IQ) as measured by the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). CONCLUSIONS: Although subthreshold autistic traits are difficult to define due to the sometimes vague border between typical and atypical development, there may be a large number of preschool children with subthreshold autistic traits, who may have an increased risk for a variety of different emotional/behavioral difficulties as well as lower cognitive functioning.
