ABSTRACT

Background/Aims@#Patients with achalasia-related esophageal motility disorders (AEMDs) frequently present with dilated and sigmoid esophagus, anddevelop esophageal diverticulum (ED), although the prevalence and patients characteristics require further elucidation. @*Methods@#We conducted a multicenter cohort study of 3707 patients with AEMDs from 14 facilities in Japan. Esophagography on 3682 patients were analyzed. @*Results@#Straight (n = 2798), sigmoid (n = 684), and advanced sigmoid esophagus (n = 200) were diagnosed. Multivariate analysis revealed that long disease duration, advanced age, obesity, and type I achalasia correlate positively, whereas severe symptoms and integrated relaxation pressure correlate negatively with development of sigmoid esophagus. In contrast, Grade II dilation (3.5-6.0 cm) was the most common (52.9%), while grade III dilation (≥ 6 cm) was rare (5.0%). We found early onset, male, obesity, and type I achalasia correlated positively, while advanced age correlated negatively with esophageal dilation. Dilated and sigmoid esophagus were found mostly in types I and II achalasia, but typically not found in spastic disorders. The prevalence of ED was low (n = 63, 1.7%), and non-dilated esophagus and advanced age correlated with ED development. Patients with right-sided ED (n = 35) had a long disease duration (P = 0.005) with low integrated relaxation pressure values (P = 0.008) compared with patients with left-sided ED (n = 22). Patients with multiple EDs (n = 6) had lower symptom severity than patients with a single ED (P = 0.022). @*Conclusions@#The etiologies of dilated esophagus, sigmoid esophagus, and ED are considered multifactorial and different. Early diagnosis and optimal treatment of AEMDs are necessary to prevent these conditions.

ABSTRACT

The patient was a 48-year-old woman who had been taking oral steroids for dermatomyositis since age 39. The patient experienced an episode of sudden chest tightness at age 48, and acute myocardial infarction was suspected. Coronary angiography revealed a right coronary artery occlusion ; emboli (thrombi) were collected from the same site. Left cardiac ventriculography revealed the presence of a mobile thrombotic mass in the ascending aorta. Although heparin therapy was initiated considering the possibility of thrombosis, no shrinkage of the mass was observed, and surgery was planned as per treatment guidelines. The mass was a rod-shaped thrombus measuring 20 mm×7 mm×7 mm attached to the aortic wall, approximately 2.5 cm distal from the entrance to the right coronary artery. Since the aortic wall at the site of the tumor attachment was normal, surgery involved only removal of the mass. A histopathological assessment revealed that the mass was a mixed thrombus containing both white and red thrombotic components. The patient was started on postoperative oral antiplatelet and anticoagulant drug therapy to prevent additional thrombosis, and no recurrence has been noted at 1 year postoperative.

ABSTRACT

PURPOSE: Peripheral artery disease (PAD) is a form of arteriosclerosis that occurs in the extremities and involves ischemia. Previous studies have reported that patients with periodontitis are at high risk for PAD. However, the relationship between these 2 diseases has not yet been fully elucidated. In this cross-sectional study, we investigated this relationship by comparing patients with PAD to those with arrhythmia (ARR) as a control group. METHODS: A large-scale survey was conducted of patients with cardiovascular disease who visited Tokyo Medical and Dental University Hospital. We investigated their oral condition and dental clinical measurements, including probing pocket depth, bleeding on probing, clinical attachment level, and number of missing teeth; we also collected salivary and subgingival plaque samples and peripheral blood samples. All patients with PAD were extracted from the whole population (n = 25), and a matching number of patients with ARR were extracted (n = 25). Simultaneously, ARR patients were matched to PAD patients in terms of age, gender, prevalence of diabetes, hypertension, dyslipidemia, obesity, and the smoking rate (n = 25 in both groups). Real-time polymerase chain reaction was performed to measure the bacterial counts, while the enzyme-linked immunosorbent assay method was used to measure anti-bacterial antibody titers and proinflammatory cytokine levels in serum. RESULTS: PAD patients had more missing teeth (18.4±2.0) and higher serum levels of C-reactive protein (1.57±0.85 mg/dL) and tumor necrosis factor-alpha (70.3±5.7 pg/mL) than ARR patients (12.0±1.7, 0.38±0.21 mg/dL, and 39.3±4.5 pg/mL, respectively). Meanwhile, no statistically significant differences were found in other dental clinical measurements, bacterial antibody titers, or bacterial counts between the 2 groups. CONCLUSIONS: Our findings suggested that PAD patients had poorer oral and periodontal state with enhanced systemic inflammation.

ABSTRACT

<p>A 55-year old man was admitted to our hospital owing to endograft collapse after TEVAR. He had undergone total arch replacement for acute aortic type A dissection at age 39, and undergone thoracic endovascular aortic repair (TEVAR) for chronic aortic type B dissection at age 54. TEVAR was successfully performed and the false lumen was shrunk. However, one year after TEVAR, computed tomography showed endograft collapse. Technical success was not achieved by the balloon technique to treat endograft collapse, so we performed additional TEVAR. After this procedure, endograft collapse was repaired. The postoperative course was uneventful.</p>

ABSTRACT

  Epidermal growth factor receptor (EGFR) gene mutation examination is now performed in most medical institutions in order to select the molecular targeted medicine for lung cancer. It became clear that the positive rate of the biopsy material was lower than that of the surgical sample in this hospital. The cause was attributed to false negatives due to low tumor cell content in biopsy specimens. We investigated the presence of the mutation using surgical samples and preoperative biopsy specimens from the same patients in 13 cases. Furthermore, we investigated the tumor cell content of the biopsy specimens by cell counting. Results showed that 3 of 6 biopsy specimens that were associated with positive surgical samples were judged to be negative. The tumor cell content was less than 5% in all negative cases. Regarding EGFR gene mutation examination, we should carefully determine tumor cell content when using biopsy specimens.

ABSTRACT

The patient was a 68-year-old woman with chief complaints of severe lumbago, left lateral abdominal pain and high fever. Computer tomography (CT) at a local hospital showed a left psoas abscess and a low density area around the terminal aorta. Blood tests indicated a high inflammatory response and MSSA was detected in a blood culture. Control of the infection was first attempted with antibiotics, but CT showed a pseudoaneurysm at the terminal aorta, and therefore she was transferred to our hospital. We diagnosed infected abdominal aortic and left common iliac aneurysms complicated by an MSSA psoas abscess, and performed extra-anatomic reconstruction with axillo-bifemoral bypass, aneurysmectomy and omentopexy in the psoas abscess cavity. Because of massive intestinal edema and mesentery, we attempted temporary abdominal closure with the vacuum-assisted closure (VAC) technique, and finally succeeded in closing without abdominal infection in the 6th operation, 42 days after the first operation. Infected abdominal aortic aneurysm complicated by psoas abscess is extremely rare and life threatening. The VAC technique is very effective not only in avoiding abdominal compartment syndrome but also in avoiding abdominal infection.
