Cavernous hemangioma of the stomach: A case report and review of the literature

A cavernous hemangioma of the stomach in a 41-year-old Japanese man was reported. The patient had numerous hemorrhagic telangiectasias in the skin and was also diagnosed as having a submucosal tumor of the stomach by an incidental upper gastrointestinal X-ray study. Wedge resection of the stomach was performed. The tumor was located in the submucosal, proper muscular and subserosal layers. The resected specimen showed proliferation of vascular spaces lined with a layer of endothelial cells and filled with red blood cells together with a partially calcified thrombus. The histopathologic diagnosis was cavernous hemangioma of the stomach with calcified thrombus. The patient has been doing well for twenty years. We report the case and briefly review the literature.

Case report of perineal hernia after laparoscopic abdominoperineal resection

Perineal hernia (PH) is a rare complication following laparoscopic abdominoperineal resection (APR) for rectal cancer. We present a case report of perineal hernia after laparoscopic APR and discuss its management. The patient was a 77‐year‐old man who was diagnosed with lower rectal cancer. He underwent laparoscopic APR and bilateral lateral lymph node dissection. Two months after the surgery, pain and bulging in the perineal region developed, and PH was diagnosed by CT. Repair with a polypropylene mesh was performed using a combination of laparoscopic abdominal and transperineal approaches. Reportedly, the incidence of secondary PH after APR has increased along with the rate of laparoscopic surgery. Treatment of secondary PH with transperineal repair alone may cause injuries to other organs because of adhesion of the pelvic viscera. In the present case, we safely repaired the hernia repair using a laparoscopy‐assisted perineal approach.     

Liver abscess due to <Emphasis Type="Italic">Fusobacterium</Emphasis> species detected on ultrasonography: a case report

An oral infection harboring Fusobacterium species can gain entrance to the liver via hematogenous spread in the form of septic embolus, and can thereby cause abscesses. Such spread, described as Lemierre syndrome, is life threatening. We present such a case history of a man in his mid-40s, who presented with infection and Fusobacterium liver abscess with an acute fulminant disease course. The initial diagnosis was arrived at by ultrasound imaging and blood investigations. He was treated with antibiotics, ultrasound-guided liver abscess drainage, and extraction of the infected molar tooth. He was discharged 6 weeks after admission. To date, there have been no reports describing the ultrasound images of a Fusobacterium liver abscess in detail. Hence, we herein present the ultrasound images of a Fusobacterium liver abscess.     

72-Week Safety and Tolerability of Dimethyl Fumarate in Japanese Patients with Relapsing-remitting Multiple Sclerosis: Analysis of the Randomised,Double Blind,Placebo-Controlled,Phase III APEX Study and its Open-Label Extension

Introduction

The long-term safety of dimethyl fumarate (DMF) in patients with relapsing-remitting multiple sclerosis (RRMS) has been studied in mainly Caucasian patients. The present interim analysis aimed to evaluate the 72-week safety of DMF in Japanese patients with RRMS.

Methods

Safety data of Japanese subjects enrolled in the 24-week randomised, double-blind, placebo-controlled APEX study (Part I) and its following open-label extension (Part II) were analysed at 72 weeks from the beginning of Part I. In Part I, subjects were randomised to DMF treatment or matching placebo while all subjects received DMF treatment during Part II. Adverse events (AEs) reported throughout the study period were recorded.

Results

Overall, 109 Japanese subjects completed 72 weeks of treatment. The incidence of AEs and serious AEs was 95% and 19%, respectively, in the DMF group compared with 84% and 18%, respectively, in the placebo group at 24 weeks. Common AEs (at least 5%) reported with treatment included nasopharyngitis, flushing, hot flush, gastrointestinal events, pruritus, rash, headache, increased alanine aminotransferase (ALT) and aspartate aminotransferase (AST). AEs led to discontinuation of DMF in 5% of patients and included MS relapse, flushing, abdominal pain, liver disorder and increased ALT/AST. After an initial decrease from baseline of 17% in the DMF group at week 24, the mean lymphocyte counts stabilised and were maintained until week 72. No opportunistic/serious infections nor malignancies were reported with DMF treatment. The incidences of AEs, serious AEs, and discontinuation due to AEs were similar between the DMF and the placebo groups.

Conclusion

The 72-week safety profile of DMF in Japanese patients with RRMS was consistent with previous studies that enrolled mostly Caucasian patients, with a lower incidence of flushing and related symptoms and a lower reduction in the lymphocyte count compared with previous reports.

Long-term effectiveness of an inpatient pulmonary rehabilitation program for elderly COPD patients: comparison between young-elderly and old-elderly groups

OBJECTIVE: To evaluate the long-term effects of pulmonary rehabilitation in elderly COPD patients, we monitored patients for 1 year after they completed a 2-week inpatient pulmonary rehabilitation program. We also compared the effects of pulmonary rehabilitation on young-elderly (age 65-74 years) and old-elderly (age 75 years or over) COPD patients. METHODOLOGY: Fifty-nine elderly COPD patients (mean age 72.8 years) were studied. They underwent a comprehensive 2-week inpatient pulmonary rehabilitation program incorporating 10 exercise sessions, each of which included endurance training of the lower extremities, peripheral muscle conditioning training of the upper and lower extremities, and stretching, along with various education sessions. The effects of pulmonary rehabilitation were evaluated at 3, 6, and 12 months after completion of the program. RESULTS: Overall, patient health-related quality of life (HRQoL) as assessed by a QoL scale, and dyspnoea as assessed by an oxygen cost diagram, improved significantly over the 12-month period. Exercise capacity assessed by a 6-min walking distance test (6MWD) was similarly significantly improved. However, there was some fall-off in terms of the distance walked 12 months after pulmonary rehabilitation. The improvements in exercise capacity, dyspnoea, and HRQoL did not differ between the two groups, with the exception that the 6MWD (P < 0.01) and the QoL scale (P < 0.05) at 3 months post-pulmonary rehabilitation were significantly higher in the old-elderly group. CONCLUSIONS: Pulmonary rehabilitation is an effective treatment in terms of improving dyspnoea, exercise capacity and HRQoL in elderly COPD patients, and the benefits are almost comparable for young-elderly and old-elderly patients.     

Long-term follow up of esophageal varices after balloon-occluded retrograde transvenous obliteration for gastric varices.

Aim: Because the procedure of balloon-occluded retrograde transvenous obliteration (B-RTO) causes extensive thrombosis of the major shunt that connects the spleen and gastric/renal venous systems, an increase in portal pressure is unavoidable. The aim of the present study was to assess the long-term outcome of B-RTO, including changes in esophageal varices. Methods: B-RTO was conducted in 22 patients with gastric varices, who were divided according to the severity of esophageal varices at baseline; there were no esophageal varices (n = 7), F(1) varices (n = 11), and F(2) varices (n = 4). The outcome measures included the development/worsening of esophageal varices after B-RTO and survival rates. Results: The cumulative bleeding-free probability for all 22 patients at 3 years after B-RTO was 100%. The overall 3-year survival was 94.4%. Seven patients who had no esophageal varices prior to B-RTO did not develop any after the procedure. Seven (63.6%) of the 11 patients with stage F(1) esophageal varices prior to B-RTO showed no changes in the varices after B-RTO, while two patients progressed to F(2) varices and two developed F(3) varices. The cumulative treatment-free probability of the esophageal varices at 24 months after B-RTO was 100% for patients without esophageal varices at baseline, 80.8% for patients with pre-existing F(1) varices, and 75% for those with pre-existing F(2) varices. Conclusion: Although the B-RTO procedure is considered useful for the treatment of gastric varices, changes in hemodynamics due to obliteration of this major shunt must be taken into account and observed closely.     

Gastric Mucosal Injury Induced by Local Ischemia-Reperfusion in Rats (Role of Endogenous Endothelin-1 and Free Radical)

We investigated the role of an endogenousvasoconstrictor peptide endothelin-1 (ET-1) and freeradicals in local gastric ischemia-reperfusion injury inrats. Local gastric ischemia was induced by clamping the left gastric artery for 15 min andreperfusion was done for 10-30 min in the presence of150 mM exogenous HCl intragastrically. Local gastricischemia and reperfusion resulted in significantmacroscopic and microscopic gastric mucosal damage togetherwith elevation of gastric tissue ET-1 concentration.Gastric tissue ET-1 was found to increase after 15 minof ischemia alone and also with 30 min of reperfusion. A novel nonpeptide endothelin receptorantagonist, bosentan, or a combination of radicalscavengers (superoxide dismutase, catalase, anddeferoxamine) both attenuated gastric mucosal injury.However, the greater protection observed with bosentan thanwith radical scavengers might reflect a preferentialrole of endothelin-1 in this type of injury.     

Relation of iodine-123 metaiodobenzylguanidine myocardial scintigraphy to endomyocardial biopsy findings in patients with dilated cardiomyopathy

Background: Iodine-123 metaiodobenzylguanidine (¹²³I-MIBG) concentrates in adrenergic neurons and has been developed for evaluation of the sympathetic nervous system. Recent studies have demonstrated that the normal heart is clearly visualized by ¹²³I-MIBG cardiac scintigraphy, whereas abnormal ¹²³I-MIBG myocardial uptake and washout have been demonstrated in patients after myocardial infarction and in patients with congestive cardiomyopathy, long QT syndrome, and ventricular tachycardia. Hypothesis: Based on evidence from recent studies, it can be hypothesized that ¹²³I-MIBG uptake is related to histopathologic changes in the myocardium. Methods: The relation of ¹²³I-MIBG uptake to the histologic findings for the heart was studied in 24 patients with dilated cardiomyopathy (DCM). The study group did not include patients with complicating disorders that primarily affect the adrenergic nervous system. The ¹²³I-MIBG uptake was visually assigned one of four grades using the two criteria of the mean score for six regional uptake grades (mean score) and the global score obtained by visual evaluation of the entire image (global score). The ¹²³I-MIBG uptake score was also determined for the region at which the biopsy specimen was obtained (biopsy region score). The histologic findings were evaluated by assigning one of four grades for each of the following five factors: myocyte hypertrophy, myocardial fibrotic change, myocyte degeneration and necrosis, mononuclear cell infiltration, and myocyte disarray. The sum for all grades was defined as the total score, and the global score was also assigned to the overall histologic findings. Results: All of the global, mean, and biopsy region scores for ¹²³I-MIBG uptake correlated significantly with the global and total scores for the histologic findings. Among the histologic factors, myocyte degeneration showed score correlated with all global, mean, and biopsy region scores for the uptake. Myocyte hypertrophy was associated weakly with the ¹²³I-MIBG uptake scores. Conclusion: These results indicate that ¹²³I-MIBG uptake imaging is associated with histopathologic abnormalities in patients with DCM.
