Besides the vascular changes caused by arteriosclerosis the compression stenosis is the most frequent form of the isolated restriction of the arteria coeliaca. The compression of the arteria coeliaca, caused by the ligamentum arcuatum medianum or a fribromatous ganglion tissue, can cause complaints similar to the symptoms of angina abdominalis: pains in the epigastrium, postprandial pains, loss of weight, nausea/vomiting, diarrhea, 93% of the patients with severe vascular compression have an abdominal vascular murmur. Of 31 patients with angiographically proved compression stenosis, 11 patients suffering from occlusion or intense stenosis had to be operated because of heavy complaints. The angiographic and intraoperative findings allow the conclusion that there is a connection between the extent of the stenosis and the clinical appearance. The decompression of the arteria coeliaca, in other words the detachment of the compressing tissue leads to total complaintlessness in 83% of the patients. If the arteria coeliaca is hypoplastic a vessel widening or a bypass operation is necessary to establish normal blood circulation in the epigastric organs.

A case of a basilar bifurcation aneurysm associated with common carotid artery occlusion is reported. A 40-year-old woman was admitted to our hospital with severe headache and nausea. On admission, no neurological abnormality was observed. CT scan showed thin subarachnoid hemorrhage in the basal cistern. Left vertebral angiograms revealed a basilar bifurcation aneurysm located in the high position. Also, the left internal and external carotid arteries were supplied through the anastomotic muscle branches of the left occipital and vertebral artery. The trunk of the left common carotid artery was not visualised from its origin on the aortogram. CT scan at the level of C6 showed thinning of the left common carotid artery and contrast enhancement study indicated occlusion. Neck clipping of the aneurysm was successfully performed by right trans-sylvian approach. Right zygomatic arch was removed to obtain a wider operative field for avoiding further retraction of the brain tissue. The postoperative course was uneventful except transient disorientation for two weeks. It has been well known that internal carotid artery occlusion may be associated with cerebral aneurysm in some cases. However, it seemed to be a rather rare case that the common carotid artery occlusion due to arteriosclerosis was associated with cerebral aneurysm. Hemodynamic factor was positively suggested for aneurysmal formation in this case.

A study was carried out in 127 patients (94 males and 33 females) presenting with arteriosclerosis (88 patients) or diabetic vasculopathy (39 patients) in different stages of severity (Fontaine) to assess the effectiveness and tolerance of treatment with high doses of pentoxifylline. Patients received a daily dosage of 2200 mg, given as 800 mg orally and 300 mg by intravenous infusion in saline twice daily, for a mean period of 15.8 days. Relevant clinical parameters were assessed and measurements made of biological and laboratory indices before and after treatment. The results showed that intermittent claudication was improved in 52.4% of the arteriosclerotic and 50% of the diabetic patients Stage II disease, pain at rest disappeared in 64% and 78% of patients in Stage III, respectively, and trophic lesions in Stage IV patients were reduced or became less clearly marked in 47% and 44%, respectively. Arterial blood pressure, recorded on the tibial arteries using Doppler ultrasound, showed a mean increase of 18%, but no significant changes in blood flow were evident from rheographic examination. Whole blood erythrocyte filtration time was reduced by a mean of 8%. The main changes in the biological indices after treatment were decreases in haematocrit, mean corpuscular volume and blood fibrinogen values, but these were not statistically significant. The other variables showed little if any change. Side-effects initially reported by the patients consisted of headache, nausea, sweating, pruritus and general malaise, and were mainly associated with the infusion time and regressed in most cases when this was extended.

Prostacyclin (PGI2) was given intravenously in doses of 1 to 5 ng/kg/min to eight consecutive patients with end stage peripheral arteriosclerosis and ischaemic ulcers. Seven patients had intense ischaemic pains. Complete or partial healing of ulcers were seen in six cases (complete in three). In those whose ulcers healed (complete or partially) relief of ulcer pain was remarkable. Acute studies of the effect of prostacyclin on skin temperature of ischaemic areas showed no correlation with clinical effects. Seven patients had more or less pronounced subjective side effects, most often flushing, nausea, headache and uneasiness. As we previously have seen equally good healing and pain relieving effects by the administration of prostaglandin E1 without these side effects the latter compound is so far preferred in the treatment of severe peripheral artery disease. Controlled studies of the effect are needed.

The Aschner and Czermak-Hering tests were carried out in 7 normal young males and 15 elderly patients with cerebral arteriosclerosis. Alterations in the heart rate, blood pressure and blood flow in the internal carotid artery and brachial artery were studied by means of the on-line Doppler ultrasonic apparatus before, during and after the maneuvers, simultaneously and continuously. Aschner Test. Bradycardia, biphasic alteration of blood pressure, increase of blood flow in the internal carotid artery and decrease of blood flow in the brachial artery were observed in the maneuver. The changing rate of the findings was diversified individually. However, no significant difference was observed between the normal young males and the elderly patients. Side effects consisted of slight and transient nausea and dizziness in 6 subjects. Czermak-Hering Test. Bradycardia, hypotension, and decrease of blood flow in the brachial artery were observed in the maneuver. The changing rate of the findings is more conspicuous in the elderly patients than in the normal young males. Alterations in the blood flow in the internal carotid artery were observed. There was a conspicuous increase of the blood flow in the internal carotid artery on the noncompressed side during the maneuver in all the normal young males and in half of the elderly patients. The remainder of the elderly patients showed either no alteration or decrease of the blood flow in the internal carotid artery on the noncompressed side. Slight nausea in 2 subjects, slight dizziness in 5 subjects, and moderate disturbance of consciousness in 1 subject were observed as side effects. The results indicate that the Czermak-Hering test will be more advantageous in investigating the autonomic nervous function (vasovagal reflex) and autoregulation of cerebral circulation in elderly subjects.

A 42-year-old woman was administered a cleansing enema to treat chronic constipation. Immediately after the procedure she developed intense pain in the abdominal region, nausea, vomiting, and rectal bleeding. The patient, who was in good general health, had been on contraceptive administration of Depo-Provera (150 mg each month) for 1 year. Radiological investigation, endoscopy and histopathological examinations revealed acute ischemic colitis. A left hemicolectomy was performed with colorectal anastomosis through laparotomy; the postoperative period was good and the patient was discharged in good health. The majority of cases of ischemic colitis occur in persons of advanced age, because of arteriosclerosis. In young female patients it is necessary to systematically investigate contraceptive use as a possible iatrogenic cause; surgery may be indicated in some cases.

The aims of the present open, non-comparative survey were to study the safety and efficacy of iopentol (Imagopaque, Nycomed Imaging AS, Oslo, Norway) in a large patient group. In a series of German centres, 3,587 patients underwent various contrast-enhanced examinations with iopentol. The most frequent examinations were computed tomography (CT) (1,740), phlebography (462), and digital subtraction angiography (DSA) (493). Only 82 patients (2.3%) experienced one or more adverse events. Sixty-one (1.7%) of these events were possibly or probably caused by the contrast medium. A total of 111 adverse events were registered, 54 of mild, 42 of moderate and 12 of strong intensity, and 51 events required treatment. The most frequent adverse events were nausea (34), erythema (14) urticaria (9), taste sensation (6), circulatory reactions (5) and angina pectoris (5). The frequencies of adverse events were 2.9% in CT, 2.0% in DSA, 2.0% in phlebography, 1.6% in cardioangiography, and 0.4% in urography. Patients with arteriosclerosis, an earlier contrast medium reaction, multimorbidity or age over 70 years had a statistically significantly higher risk of experiencing an adverse event. Patient tolerance was very good; the mean score was 83% on a visual analogue scale (VAS) ranging from extremely bad (0%) to extremely good (100%). Efficacy, as measured on VAS, was determined. Technical quality was scored as 80%, contrast enhancement within the vessels as 80% and delineation of lesions as 79%. The results from this large patient population confirms the experience from clinical practice that iopentol is a safe, well tolerated and efficient contrast medium.

Coronary artery aneurysms are uncommon and the prevalence in patients undergoing coronary artery angiography is 1.5-4.9%. The most common cause of coronary artery aneurysm is arteriosclerosis, followed by Kawasaki disease, periarteritis nodosa, systemic lupus erythematosus, syphilis, rheumatic fever, congenital heart disease and trauma. Most coronary aneurysms remain asymptomatic. Patients may present symptoms of angina or myocardial infarction due to thrombosis within the aneurysm. This would lead to occlusion of the coronary artery or to distal thromboembolisms. There is no consensus on how to manage coronary artery aneurysms. Medical therapies include aspirin as well as warfarin. Surgery may be performed in patients with a large aneurysm, i.e. when the risk of rupture or thrombosis is high. We present a 60-year-old female patient with symptoms of a transient ischaemic attack followed by a period of fever, nausea, vomiting and ecchymoses on the lower extremity. Transthoracic and transoesophageal echocardiography was suggestive of a tumour located at the basis of the lateral wall of the right atrium. Heart surgery revealed, however, a large right coronary aneurysm and an atrial septum defect of the secundum type.

We report carotid ultrasonographic findings in moyamoya disease. A 44-year-old man was admitted to our hospital because of fever, headache and nausea. Neurological examination showed neck stiffness and Kernig's sign but he was otherwise normal. Brain computed tomography showed hemorrhage in the right thalamus and the lateral ventricle. Conventional carotid ultrasonography (CCU) detected marked narrowing of the right internal carotid artery (ICA) at the proximal portion without arteriosclerosis, which fulfilled the criteria of bottle neck sign, namely, the ratio of diameter of proximal portion of ICA to that of the distal portion of common carotid artery (CCA) was less than 0.5. Additionally, CCU as well as transoral carotid ultrasonography (TOCU) showed the diameter of the ICA to be smaller than that of the external carotid artery (ECA) (diameter reversal sign). These signs strongly suggested moyamoya disease. Cerebral angiography confirmed the occlusions of intracranial ICA and moyamoya vessels. Bottle neck sign and diameter reversal sign of the carotid artery on carotid ultrasonography are useful for the early detection of moyamoya disease.

The fluoroquinolones ciprofloxacin, levofloxacin, moxifloxacin and gemifloxacin are widely used for the treatment of various types of bacterial infections. Overall, these antibacterial agents can be considered safe and well tolerated drugs. Comparative studies have evaluated the use of quinolones in elderly and younger populations. Although age per se does not seem to decrease their tolerability, specific adverse effects of the quinolones must be considered when they are chosen for antibacterial treatment. Renal function declines consistently with age and doses of renally excreted quinolones (e.g. ofloxacin, levofloxacin, gatifloxacin) need to be adjusted if a clinically relevant reduction of creatinine clearance is identified. Reactions of the gastrointestinal tract, such as nausea, dyspepsia, vomiting or diarrhoea, are among the most often registered adverse drug reactions during therapy with fluoroquinolones. Treatment with a quinolone causes diarrhoea less frequently than treatment with other classes of antimicrobials. Conflicting data have been published with respect to the incidence of Clostridium difficile-associated diarrhoea in quinolone-treated patients. Hypersensitivity reactions, often manifested on the skin, occur less commonly during therapy with quinolones than, for example, during therapy with beta-lactam antibacterials. Adverse reactions of the CNS are of particular concern in the elderly population. Given the CNS excitatory effects of quinolones, elderly patients should be monitored carefully for such symptoms. It is likely that many signs of possible adverse reactions, such as confusion, weakness, loss of appetite, tremor or depression, are often mistakenly attributed to old age and remain unreported. Quinolones should be used with caution in patients with known or suspected CNS disorders that predispose to seizures (e.g. severe cerebral arteriosclerosis or epilepsy). Quinolones can cause QT interval prolongation. They should be avoided in patients with known prolongation of the QT interval, patients with uncorrected hypokalaemia or hypomagnesaemia and patients receiving class IA (e.g. quinidine, procainamide) or class III (e.g. amiodarone, sotalol) antiarrhythmic agents. Tendinitis and tendon ruptures are recognized as quinolone-induced adverse effects that can occur during treatment or as late as several months after treatment. Chronic renal diseases, concomitant use of corticosteroids and age >60 years are known risk factors for quinolone-induced tendopathies. Overall, the specific adverse-effect profile of quinolones must be considered when they are chosen for treatment of bacterial infections. Because of physiological changes in renal function and when certain co-morbidities are present, some special considerations are necessary when elderly patients are treated with these drugs.
