We present one case of true aneurysm of the branchial artery which is very rare among peripheral aneurysms. A 52-year-old woman developed a bruise on the right upper arm around June 1993, but did nothing about it because she felt no symptoms. A pulsating mass became palpable at this site around the following month. Digital subtraction angiography revealed an aneurysm formation of 1.5×1.5cm in size in the right brachial artery. Operative findings showed that the wall of the aneurysm joined the normal region and all the vascular layers in the aneurysm were maintained. After resection of the aneurysm, end-to-end anastomosis was carried out. A diagnosis of true aneurysm was confirmed by the pathohistological findings that the vascular three-layer structure was maintained, with few arteriosclerotic changes.

STUDY DESIGN: Retrospective cross-sectional study. PURPOSE: To determine the prevalence of idiopathic scoliosis, define the distribution of the curve magnitude, evaluate the accuracy of Moire topography as a screening tool, and investigate the cost-effectiveness of our screening system. OVERVIEW OF LITERATURE: Early detection of idiopathic scoliosis provides the opportunity for conservative treatment before the deformity is noticeable. We believe that scoliosis screening in schools is useful for detection; however, screening programs are controversial owing to over referral of students who do not require further testing or follow-up. In Japan, school scoliosis screening programs are mandated by law with individual policies determined by local educational committees. We selected Moire topography as the scoliosis screening tool for schools in Nara City. METHODS: We selected Moire topography as the scoliosis screening tool for schools in Nara City. We screened boys and girls aged 11-14 years and reviewed the school scoliosis screening results from 1990 to 2012. RESULTS: A total of 195,149 children aged 11-14 years were screened. The prevalence of scoliosis (defined as > or =10degrees curvature) was 0.057%, 0.010%, and 0.059% in fifth, sixth, and seventh grade boys and 0.337%, 0.369%, and 0.727% in fifth, sixth, and seventh grade girls, respectively. The false-positive rate of our Moire topography was 66.7%. The minimum cost incurred for scoliosis detection in one student was 2,000 USD. CONCLUSIONS: The overall prevalence of scoliosis was low in the students of Nara City schools. Over 23 years, the prevalence of scoliosis in girls increased compared to that in the first decade of the study.

BACKGROUND: Estimates of daily sodium (Na) and potassium (K) excretion were explicitly biased when using equations for adults. We aimed to develop equations to estimate them using overnight urine from Japanese children and adolescents. METHODS: The subjects comprised 70 students aged 10.49-15.76 years: validation group, n = 34; and verification group, n = 36. Each subject performed two operations of overnight spot urine (U RESULTS: In validation, we formulated Na excretion (mg d CONCLUSION We obtained validated equations to estimate daily Na and K excretion with accessible variables such as Na, K, and Cr concentrations of overnight urine, body height and weight, and age for children and adolescents. When using the obtained equations, caution should be paid to small but definite biases and measurement errors.

PURPOSE: Since oncological outcomes of transanal colorectal tube (TCT) placement, an endoscopic treatment for colorectal cancer (CRC) with acute colorectal obstruction (ACO), remain unknown, this study analyzed long-term outcomes of TCT placement for stage II/III CRC with ACO. MATERIALS AND METHODS: Data were retrospectively reviewed from consecutive patients with distal stage II/III CRC who underwent surgery between January 2007 and December 2011 at two Japanese hospitals. One hospital conducted emergency surgery and the other performed TCT placement as the standard treatment for all CRCs with ACO. Propensity score (PS) matching was used to adjust baseline characteristics between two groups. RESULTS: Among 754 patients with distal stage II/III CRC, 680 did not have ACO (non-ACO group) and 74 had ACO (ACO group). The PS matching between both hospitals identified 234 pairs in the non-ACO group and 23 pairs in the ACO group. In the non-ACO group, the surgical quality was equivalent between the two institutions, with no significant differences in overall survival (OS) and disease-free survival (DFS). In the ACO group, the rate of primary resection/anastomosis was higher in the TCT group than in the surgery group (87.0% vs. 26.1%, p < 0.001). No significant differences were noted between the surgery and the TCT groups in OS (5-year OS, 61.9% vs. 51.5%; p=0.490) and DFS (5-year DFS, 45.9% vs. 38.3%; p=0.658). CONCLUSION: TCT placement can achieve similar long-term outcomes to emergency surgery, with a high rate of primary resection/anastomosis for distal stage II/III colon cancer with ACO.

Background/Aims: Several studies have assessed the effect of cool temperature on colonic peristalsis. Transient receptor potential melastatin 8 (TRPM8) is a temperature-sensitive ion channel activated by mild cooling expressed in the colon. We examined the antispasmodic effect of cool temperature on colonic peristalsis in a prospective, randomized, single-blind trial and based on the video imaging and intraluminal pressure of the proximal colon in rats and TRPM8-deficient mice. Methods: In the clinical trial, we randomly assigned a total of 94 patients scheduled to undergo colonoscopy to 2 groups: the mildly cool water (n = 47) and control (n = 47) groups. We used 20 mL of 15°C water for the mildly cool water. The primary outcome was the proportion of subjects with improved peristalsis after treatment. In the rodent proximal colon, we evaluated the intraluminal pressure and performed video imaging of the rodent proximal colon with cool water administration into the colonic lumen. Clinical trial registry website (Trial No. UMIN-CTR; UMIN000030725). Results: In the randomized controlled trial, after treatment, the proportion of subjects with no peristalsis with cool water was significantly higher than that in the placebo group (44.7% vs 23.4%; P < 0.05). In the rodent colon model, cool temperature water was associated with a significant decrease in colonic peristalsis through its suppression of the ratio of peak frequency (P < 0.05). Cool temperaturetreated TRPM8-deficient mice did not show a reduction in colonic peristalsis compared with wild-type mice. Conclusion For the first time, this study demonstrates that cool temperature-dependent suppression of colonic peristalsis may be associated with TRPM8 activation.

A 31-year-old woman infected with severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) at 33-weeks pregnant was subject to cesarean delivery due to a worsening respiratory condition. On the fourth day of illness, the patient was placed on a ventilator, with extracorporeal membrane oxygenation (ECMO) treatment initiated on the ninth day. Passive range of motion (ROM) training started on the day 33 of illness. She was weaned off ECMO on day 55 of illness and taken off of the ventilator on day 8. The tracheostomy tube was replaced with a speech cannula on day 87 of illness, at which time the patient began to complain of pain during passive ROM training. Plain X-ray photography and computed tomography (CT) showed ossification around the bilateral shoulder and hip joints, as well as on medial thighs, accompanied by an alkaline phosphatase (ALP) value of 942 U/L. She was subsequently diagnosed with heterotopic ossification, after which passive ROM training was changed to protective ROM training, in addition to treatment with indomethacin farnesyl and etidronate disodium. The patient was transferred to our hospital on day 122 of illness for the purpose of continuing rehabilitation. On day 155 of illness, ossification decreased on the medial thighs, according to CT. She was able to walk independently indoors and was discharged home on day 181 of illness. This case demonstrates the importance of checking the ALP levels and palpating the periarticular area in patients infected with SARS‑CoV‑2 before initiating passive ROM training, as well as being aware of any pain experienced during training. In the case of any abnormalities, assessing the ossification around the joints of extremities by imaging examination is a priority.

Background: The anti-programmed death 1 (PD-1) antibody has led to durable clinical responses in a wide variety of human tumors. We have previously developed the caninized anti-canine PD-1 antibody (ca-4F12-E6) and evaluated its therapeutic properties in dogs with advance-staged oral malignant melanoma (OMM), however, their therapeutic effects on other types of canine tumors remain unclear. Objective: The present clinical study was carried out to evaluate the safety profile and clinical efficacy of ca-4F12-E6 in dogs with advanced solid tumors except for OMM. Methods: Thirty-eight dogs with non-OMM solid tumors were enrolled prospectively and treated with ca-4F12-E6 at 3 mg/kg every 2 weeks of each 10-week treatment cycle. Adverse events (AEs) and treatment efficacy were graded based on the criteria established by the Veterinary Cooperative Oncology Group. Results: One dog was withdrawn, and thirty-seven dogs were evaluated for the safety and efficacy of ca-4F12-E6. Treatment-related AEs of any grade occurred in 13 out of 37 cases (35.1%).Two dogs with sterile nodular panniculitis and one with myasthenia gravis and hypothyroidism were suspected of immune-related AEs. In 30 out of 37 dogs that had target tumor lesions, the overall response and clinical benefit rates were 6.9% and 27.6%, respectively. The median progression-free survival and overall survival time were 70 days and 215 days, respectively. Conclusions The present study demonstrated that ca-4F12-E6 was well-tolerated in nonOMM dogs, with a small number of cases showing objective responses. This provides evidence supporting large-scale clinical trials of anti-PD-1 antibody therapy in dogs.
