A novel polysaccharide/zein conjugate as an alternative green plastic.

The flax seed cake is a waste product from flax oil extraction. Adding value to this wasted material aligns with the concept of circularity. In this study, we explored zein protein conjugation with flax mucilage for packaging material development.

Decreased Incidence of Oncology Admissions in 75 Helios Hospitals in Germany during the COVID-19 Pandemic.

Background: The COVID-19 pandemic lead to a massive shutdown of social life in Germany starting in March 2020. Elective medical treatment was substantially reduced but urgent diagnostics and treatment including cancer care should not have been affected.

Materials And Methods: We analyzed the number of oncology admissions to 75 German Helios hospitals during 2 time periods in 2020 and compared the data with the respective periods in 2019.

[Mycotic coronary aneurysm with Escherichia coli sepsis: a case report].

We report the case of a patient who was admitted for acute coronary syndrom associated with fever originating from urinary tract. Coronary arteriography revealed a huge coronary aneurysm which ruptured a short time after diagnosis. After surgery, it was proven to be mycotic aneurysm related to Escherichia Coli sepsis.

Postoperative ventricular arrhythmias after cardiac surgery: immediate- and long-term significance.

AF is frequent after cardiac surgery. However, ventricular arrhythmias are less known. The purpose of the study was to evaluate the causes and the prognostic significance of severe ventricular arrhythmias occurring after cardiac surgery.

[Treatment with lepirudin in heparin-induced thrombocytopenia. A case report].

We report the case of a 71 old woman presenting a bilateral massive pulmonary embolism with intraventricular right thrombus complicating heparin induced thrombocytopenia (HIT) persistent after one month of conventional anticoagulant processing. We underline the effectiveness of lepirudin (Refludan) in the curative processing of pulmonary embolism allowing here to avoid a complex surgical thromboembolectomy. We evoke the place of this molecule in the curative therapeutic strategy of HIT with thrombotic phenomena.

[Comparative outcome of aortic valve endocarditis with or without annular abscess].

Annular abscess is a not uncommon but serious complication of aortic valve endocarditis. The aim of this retrospective study was to evaluate the prognosis of aortic valve endocarditis with and without annular abscess. Between January 1981 and 1989, 122 consecutive cases of aortic endocarditis fulfilling the diagnostic criteria of Duke University were admitted to hospital.

[Development of indications in surgery of coronary revascularization. Current role of mammary-coronary anastomoses].

At a time when the cardio-surgical community has become aware that arterial revascularizations are superior to venous bypasses, GRUNTZIG (24) initiated the now well-known, and highly successful techniques of endoluminal angioplasty (P.T.C.

[Emergency coronary surgery after transluminal angioplasty. Immediate results and long-term outcome of 100 operations].

The increasing application of percutaneous transluminal coronary angioplasty (PTCA) requires evaluation of emergency coronary artery surgery for complications of this procedure. In a consecutive series of 2,576 angioplasties performed between April 1980 and January 1990, 100 patients (82 men and 18 women, average age 54 +/- 10 years, 3.9%) underwent emergency coronary artery surgery because of complications.

Early and long-term outcome after emergency coronary artery bypass surgery after failed coronary angioplasty.

From April 1980 to January 1990, among 2,576 percutaneous transluminal coronary angioplasty (PTCA) procedures, 100 patients (82 men and 18 women; mean age, 54 +/- 10 years [3.9%]) underwent emergency coronary artery bypass graft surgery. Before PTCA 56 had unstable angina, 34 had prior myocardial infarction, and 60 had single-vessel coronary artery disease.

Proximal rupture and intracoronary entrapment of a rotating device during low-speed rotational coronary angioplasty.

While attempting to recanalize a right coronary artery obstruction by using a low-speed rotating catheter (Rotacs), proximal rupture of the catheter body occurred with entrapment of the blunt tip in the obstruction. To retrieve the device, it was necessary to severe the guiding catheter and the flexible tube of the Rotacs. At low-speed rotation the flexible segment of the catheter was then pulled back.

[Intra-arterial fibrinolysis of superior mesenteric artery embolism].

Intra arterial fibrinolysis for acute mesenteric embolism. Acute mesenteric ischemia has a poor prognosis because the diagnosis is often too late (greater than 12 h), leading to a difficult surgery in old patients. The lesions of the bowel don't always allow a single operative embolectomy but often need a resection when there is a long time interval between onset of symptoms and therapy.

[Contribution of color echocardiography to the diagnosis of post-traumatic left ventricular-right atrial septal defect].

The authors report the case of an acquired left ventricle--right atrial communication after closed chest trauma. This communication was associated with rupture of the aortic isthmus and complete atrioventricular block. The left-to-right shunt which was assumed for a long time to be a small, well-tolerated, ventricular septal defect, finally required surgical repair.

[Reduction in the incidence of postoperative diaphragmatic paralysis by using a phrenic nerve protector].

A prospective study of a consecutive series of 100 patients in whom a phrenic nerve protector was used during cardiac surgery under CPB demonstrated the existence of one case of postoperative left phrenic nerve palsy and three cases of postoperative right phrenic nerve palsy. Comparison with a previous series taken as the control revealed a very significant reduction in the incidence of left phrenic nerve palsy which decreased from 8% to 1%. The incidence of right phrenic nerve palsy was not significantly decreased which corroborates the role of pericardial cooling in the aetiology of these palsies and the absence of protection of the right phrenic nerve by the system used.

[Prognostic value of two-dimensional echocardiography before aneurysmectomy in anterior aneurysm of the left ventricle].

The prognostic value of echocardiographic apical 4 chamber recordings was assessed retrospectively in 18 patients who underwent left ventricular aneurysmectomy following anterior wall myocardial infarction. After an average follow-up period of 2 years, 7 patients had died or remained in functional Classes III or IV (Group 1) and 11 patients had satisfactory clinical outcomes (Group 2). There were no significant clinical or coronary angiographic differences between the two groups.

[Retrocardiac pheochromocytoma associated with a double carotid site. Diagnostic and therapeutic discussion].

A case of cardiac paraganglioma is reported in a 30 year old man operated two years previously for bilateral carotid body paraganglioma. Due to the persistence of high catecholamine levels in the superior vena cava, a cardiac localization, suspected on echocardiography, was confirmed by coronary angiography. MRI identified the exact site of the tumour in contact with the posterior surface of the left atrium and the great vessels of the base of the heart.

[Difficulties in the echocardiographic diagnosis of false aneurysm of the left ventricle. Apropos of 2 cases].

The echocardiographic diagnostic criteria of left ventricular pseudo-aneurysm are well established: the demonstration of a narrow-necked communication between the left ventricular cavity and the aneurysm and endocardial discontinuity at the site of myocardial rupture. The authors report two cases in which these criteria were fulfilled, leading to an echocardiographic diagnosis of pseudo-aneurysm which was erroneous as the operative findings were those of true left ventricular aneurysms.

[Cardiac pheochromocytoma. Failure of classic non-invasive diagnostic methods].

We report an exceptional case of cardiac pheochromocytoma which raised problems of localization. A 30-year old man who for several years had been hypertensive was admitted for attacks of paroxysmal hypertension. Very high levels of urinary catecholamines suggested a diagnosis of pheochromocytoma, but no tumour was found at computerized tomography (CT) and metaiodobenzylguanidine (MIBG) scintigraphy.

[Percutaneous transluminal angioplasty. Is there still a role for the surgeon?].

Relating their own clinical experience and that of the medical literature, the authors examined the role of the surgeon in coronary angioplasty. Despite the considerable progress made in the management of accidents, they believe that one must be able to resort to surgery--even if the percentage of patients who undergo emergency surgery decreases significantly--in the form of a standby procedure organized according to the difficulty of the angioplasty. Moreover, the surgeon uses this technique during the procedure for additional revascularization above the graft on collateral arteries and angioplasty can and should be used in a higher number of cases as a supplement for coronary bypass procedures.

[10-year results of anastomoses of the left internal mammary artery to the anterior interventricular artery. Angiographic and radionuclide controls].

The long term patency of left internal mammary artery graft is better than that of saphenous vein graft. The aim of this study was to determined if this high patency rate was accompanied by a satisfactory myocardial perfusion. Among 143 patients treated with an internal mammary artery graft on the left anterior descending artery between 1972 and 1976, 42 patients underwent coronary angiogram and exercise tomoscintigraphy (thallium 201) over 10 years after surgery.

[Rupture of a retro-esophageal diverticulum on a right aortic arch. Apropos of a case].

Right aortic arch with retro-oesophageal left subclavian artery usually is an asymptomatic vascular abnormality. The evolutive potential of the associated retro-oesophageal diverticulum is unknown. Complications caused by the malformation are rare, but they may be extremely severe.

[Demonstration of the arterial system during phlebography of the leg for blue phlebitis].

Massive filling of thigh and calf arterial network was noted during phlebography in a patient with a typical clinical picture of "blue" phlebitis of lower limb. This paradoxical vascular injection allows support of current physiopathologic concepts of "blue" phlebitis (phlegmasia cerulea dolens).
