We report a case of an overlapping ulcerative colitis and aortitis syndrome. A 28-year-old woman with ulcerative colitis in the region from the rectum to the sigmoid colon developed left anterior cervical pain. A cervical contrast-enhanced computed tomography and an arch aortography showed diffuse narrowing of the left common carotid artery and segmental stenosis of the left subclavian artery involving the orifice of the vertebral artery, which defined the diagnosis as aortitis syndrome. HLA was positive for BW 52, which is frequently found in patient with this type of overlapping syndrome. Treatment with prednisolone was begun at an initial dose of 20mg/day, with gradual tapering to 5mg/day at 11 months later, when her symptoms had subsided and laboratory findings of inflammation had disappeared. One year later, she became apathetic in mental activity, and had a poor memory. She also complained of numbness on the left side of her face. Angiography confirmed the progression of the left common carotid narrowing causing the deterioration of her cerebral ischemic symptom. A saphenous vein bypass graft was placed between the right subclavian artery and the left common carotid artery. The postoperative course was uneventful and she had complete symptomatic relief and recovered active ordinary life. Postoperative angiography revealed the well functioning bypass graft.

Objective: Currently, Risk Management Plans (RMPs), plan that provide new risk information about drugs, are published on the Pharmaceutical and Medical Devices Agency (PMDA) website.  The aim of this study was to compare enumerated risks in RMPs to the product labeling (PL) of the drug package insert.
Methods: The risks listed in RMPs on the PMDA website were assessed on February 10, 2014.  We investigated the documentation of these risks on the PL.
Results: Seven-hundred and eighty-five risks were enumerated in the RMPs of 77 drugs.  The enumerated risks were classified as “important identified risks” (66%), “important potential risks” (22%), and “important missing information” (12%).  Ninety-four percent of risks listed in RMPs were documented on the PL.  A portion of both the “important identified risks” and “important potential risks” groups were not documented on the PL.
Conclusion: This study was clearly the relation between risks listed in RMPs and documents on the PL.  Because a portion of the risks listed in RMPs was not documented on the PL, RMPs provide more safety information.  It is necessary to better understanding their characteristics, considering RMPs are a new source of drug information.

The purpose of this study was to estimate the postoperative growth of untreated segments of the dissected aorta with non-thrombotic communicating false lumen, and also to evaluate the clinical outcome in relation to the aortic enlargement after surgery. Nineteen patients who underwent surgical treatment of aortic dissection were studied with enhanced CT scans and angiograms during the postoperative follow-up period. In Stanford type A patients, mean aortic dilatation rate calculated at the segment showing maximal dilatation was 5.1mm/year during 13-82 months (average, 41 months) after surgery, as a sequela of enlargement of the false lumen. Differences in the aortic dilatation rates between the different segments of the aorta were observed and these were per annum 4.8mm in the ascending aorta, 5.4mm in the transverse aortic arch, 4.3mm in the proximal descending aorta, 2.7mm in the distal descending aorta and 2.4mm in the abdominal aorta. In all patients, major communications were detected at the perianastomotic sites on angiography. In Stanford type B patients, false lumens with small communications were observed to show gradual thrombotic occlusion, but no significant aortic dilatation was detected during the follow-up period (13-70 months, average: 44 months), except three cases of sudden death who had major communications. Nine late events related to dissection, consisting of 4 sudden deaths suspected to be due to aortic rupture, 2 intestinal necroses and 3 cerebral infarctions, occured in 6 patients (32%), among which three patients had undergone arterial fenestration, one of whom had double barrel anastomosis. In the remaining two, major leakages were recognized at distal aortic anastomotic sites on postoperative angiography. The results of this study, we stress the importance of periodic check-ups using enhanced CT scan and if necessary, angiography after surgery of the patients having communicating false lumen. Early detection of progressive aneurysm formation and timely surgical reintervention can yield a good prognosis.

Background/Aims: Covered self-expandable metallic stents (cSEMS) have become popular for endoscopic ultrasound-guided hepaticogastrostomy with transmural stenting (EUS-HGS). We compared the time to recurrent biliary obstruction (TRBO), complications, and reintervention rates between EUS-HGS using plastic stent (PS) and cSEMS in patients with unresectable malignancies at multicenter institutions in Japan. Methods: Patients with unresectable malignant biliary obstruction who underwent EUS-HGS between April 2015 and July 2020 at any of the six participating facilities were enrolled. Primary endpoint: TRBO; secondary endpoints: rate of complications other than recurrent biliary obstruction and technical success rate of reintervention were evaluated. Results: PS and cSEMS were used for EUS-HGS in 109 and 43 patients, respectively. The TRBO was significantly longer in the cSEMS group than in the PS group (646 vs. 202 days). Multivariate analysis identified two independent factors associated with a favorable TRBO: combined EUS-guided antegrade stenting with EUS-HGS and the use of cSEMS. No significant difference was observed in the rate of complications other than recurrent biliary obstruction between the two groups. The technical success rate of reintervention was 85.7% for PS and 100% for cSEMS (p=0.309). Conclusions cSEMS might be a better option for EUS-HGS in patients with unresectable malignancies, given the longer TRBO.

BACKGROUND: Although the utility of flaps for the treatment of sternal wound infections following median sternotomy has been reported for 30 years, there have been few reports on the risk factors for complications after reconstruction. The objective of this investigation was to identify factors related to complications after the reconstruction of sternal wound infections. METHODS: A retrospective analysis of 74 patients with reconstructive surgery after sternal wound infection over a 5-year period was performed. Clinical data including age, sex, body mass index (BMI), comorbidities, bacterial culture, previous cardiac surgery, wound depth, mortality rate, type of reconstructive procedure, and complication rate were collected. RESULTS: The patients' BMI ranged from 15.2 to 33.6 kg/m2 (mean, 23.1+/-3.74 kg/m2). Wound closure complications after reconstructive surgery were observed in 36.5% of the cases. The mortality rate was 2.7%. Diabetes mellitus significantly affected the rate of wound closure complications (P=0.041). A significant difference in the number of complications was seen between Staphylococcus aureus (S. aureus) and coagulase-negative Staphylococci (P=0.011). There was a correlation between harvesting of the internal thoracic artery and postoperative complications (P=0.048). The complication rates of the pectoralis major flap, rectus abdominis flap, omentum flap, a combination of pectoralis major flap and rectus abdominis flap, and direct closure were 23.3%, 33.3%, 100%, 37.5%, and 35.7%, respectively. CONCLUSIONS: Diabetes mellitus, S. aureus, harvesting of the internal thoracic artery, and omentum flap were significant factors for complications after reconstruction. The omentum flap volume may be related to the complications associated with the omentum flap transfer in the present study.

Central venous lesions are suspected in dialysis patients who present with increased venous pressure and severe swelling of the shunt arm. Here, we report a case where contrast computed tomography (CT) was useful for diagnosis. Iopamidol 300 (20 mL) was diluted 2-fold, 30 mL of which was injected into the vein in the shunt arm at 2.0 mL/s. Imaging was started 10 s later. Fixed stenosis caused by intimal proliferation can be assessed just as effectively using contrast CT and shunt angiography. However, contrast CT is more useful than shunt angiography in the assessment of stenosis due to compression by surrounding organs and lesions, because the position of vessels relative to surrounding organs can be depicted. Contrast CT allows for safer and shorter examination compared with shunt angiography, and the diagnostic performance of a single examination can be improved using 3-dimensional reconstruction (3D) and multiplanar reformation images. Precise information obtained using contrast CT will contribute to safe and effective percutaneous transluminal angioplasty.

Purpose: Total or proximal gastrectomy of the upper-third early gastric cancer (u-EGC) often causes severe post-gastrectomy syndrome, suggesting that these procedures are extremely invasive for patients without pathologically positive lymph node (LN) metastasis. This study aimed to evaluate the clinical applicability of a stomach function-preserving surgery, local resection (LR), with prophylactic left gastric artery (LGA)-basin dissection (LGA-BD). Materials and Methods: The data of patients with u-EGC (pathologically diagnosed as T1) were retrospectively analyzed. Total gastrectomy was performed in 30 patients, proximal gastrectomy in 45, and subtotal gastrectomy in 6; the LN status was evaluated assuming that the patients had already underwent LR + LGA-BD. This procedure was considered feasible in patients without LN metastases or in patients with cancer in the LGA basin. The reproducibility of the results was also evaluated using an external validation dataset. Results: Of the 82 eligible patients, 79 (96.3%) were cured after undergoing LR + LGA-BD, 74 (90.2%) were pathologically negative for LN metastases, and 5 (6.1%) had LN metastases, but these findings were only observed in the LGA basin. Similarly, of the 406 eligible tumors in the validation dataset, 396 (97.5%) were potentially curative. Tumors in the lesser curvature, post-endoscopic resection status, and small tumors (<20 mm) were considered to be stronger indicators of LR + LGA-BD as all subpopulation cases met our feasibility criteria. Conclusions More than 95% of the patients with u-EGC might be eligible for LR + LGA-BD.This function-preserving procedure may contribute to the development of u-EGC without pathological LN metastases, especially for tumors located at the lesser curvature.

Objective：Although prediction of functional recovery after lacunar infarction is challenging, quantitative evaluation of brain imaging may be promising. In this article, we investigate association of the amount of corticospinal tract (CST) injury on Computed Tomography (CT) and functional recovery of lacunar infarction in the corona radiata.Methods：In 24 patients with lacunar infarction of the corona radiata, we investigated association of the amount of virtual CST injury with upper and lower limb motor function at 90 days after the stroke onset. The optimal area of the virtual CST to predict motor function was also determined. Finally, we evaluated whether the quantitative CST injury predicted practical motor function regarding activities of daily living.Results：The amount of virtual CST injury, evaluated with Hounsfield unit value of CT, was significantly associated with upper and lower limb function at 90 days after stroke onset. Among them, 6 mm radius CST circle for upper limb had the highest regression coefficient to predict Brunnstrom stage for the upper extremity (R2＝0.69), grip strength (R2＝0.52) and Simple Test for Evaluating Hand function (R2＝0.75). Also, 7 mm radius CST circle for lower limb had the highest regression coefficient to predict Brunnstrom stage for the lower extremity (R2＝0.51), weight bearing index (R2＝0.53) and Berg Balance Scale (R2＝0.52). These virtual CSTs predicted practical function including practical upper limb and ambulation.Conclusion：Quantitative evaluation of CST on CT predicted functional recovery after lacunar infarction of the corona radiata.
