Familial hypercholesterolaemia is a frequent, inherited, monogenic disorder, associated with accelerated development of atherosclerotic disease leading to coronary artery disease. Life expectancy of patients with familial hypercholesterolaemia is reduced by 15-30 years unless they are adequately treated with lipid-lowering therapy. Given the chronic nature of this disease, the selection of a therapeutic approach should be strongly based on its long-term safety and tolerability. The introduction of HMG-CoA reductase inhibitors has revolutionised the treatment of familial hypercholesterolaemia. Simvastatin 40-80 mg/day effectively reduces serum low density lipoprotein (LDL)-cholesterol levels. Furthermore, simvastatin reduces triglycerides and mildly raises high density lipoprotein-cholesterol levels. In addition to the hypolipidaemic effect, other potentially important effects, such as improvement of endothelial function and reduction of LDL oxidation and vascular inflammation, have been associated with HMG-CoA reductase inhibitor therapy. Simvastatin has also been shown to abolish the progression, and even facilitate the regression, of existing human atherosclerotic lesions. The good safety and tolerability profile of simvastatin is clearly highlighted by the low rate of therapy discontinuation observed in several population-based clinical trials. The most common adverse events leading to the discontinuation of therapy are gastrointestinal upset and headache. Asymptomatic elevations in liver transaminase levels and myopathy are uncommon. The overwhelming clinical evidence regarding the long-term use of HMG-CoA reductase inhibitor therapy in patients with familial hypercholesterolaemia together with the long-term safety data (particularly relating to simvastatin) provide support for the use of this drug as a first-line agent when pharmacological treatment is indicated. Early intervention with simvastatin treatment can be successfully implemented with favourable economic benefits.

Basiliximab is a chimeric anti-intcrleukin-2 receptor monoclonal antibody. Basiliximab is a glycoprotein produced by recombinant technology. It is used to prevent white blood cells from acute renal transplantation rejection. It specifically binds to and blocks the alpha chain of interleukin-2 receptors (IL-2R alpha), also known as CD25 antigen, on the surface of activated T-lymphocytes. Due to its monoclonal nature it provides safer and more predictable therapeutic, that is, immunosuppressive response of the polyclonal antibodies. The most common adverse effects in adult patients are constipation, infections, pain, nausea, peripheral oedema, hypertension, anaemia, headache, hyperkalacmia, hypercholesterolemia, increase in serum creatinine, and hypophosphataemia.

Peer-mediated learning is an effective educational strategy that is rarely used during clinical training for medical students. We developed a peer-mediated learning conference, Student-Faculty Rounds (SFR), for the ambulatory component of a medicine clerkship. Designed to broaden students' exposure to common medical problems and provide practice in small-group teaching, the 30-minute conference is conducted by each student once during their clerkship. Students choose their topics and instructional formats, but they are advised to supply written learning objectives and employ interactive, problem solving opportunities. We analysed evaluations written by 280 students and 17 faculty supervisors during 1998-2001. Students presented over 150 topics. The most common were hypercholesterolemia, diabetes, headache, smoking cessation, hypertension management, and cancer screening (each presented in 3-4% of rounds). On a scale of 10 (outstanding) to 0 (lost cause), students gave SFR a score of 9.2 (95% confidence interval 9.0-9.3). In written comments, students indicated that topics were relevant and that peers provided instruction at an appropriate level of complexity, but that quality was variable. Faculty supervisors reported that 35% of students did not provide written learning objectives and 35% chose topics too broad for a 30-minute conference. SFR is a popular conference that accomplishes its educational objectives. It recognizes students' ability to educate themselves, and introduces variability and challenge into the classroom curriculum. Adequate faculty guidance is needed to assure students design conferences for maximum educational effectiveness.

The objective was to evaluate the presence of a positive family history (FH) of vascular risk factors between patients with migraine with aura (MA) and migraine without aura (MO), and in chronic migraine (CM) compared to other headache types. As migraine patients are typically too young to have developed vascular events, studying older relatives of migraine patients may be a practical means of evaluating associations between vascular risk factors and migraine. A cross-sectional study of a clinic-based sample of adults with migraine headache was carried out at the University of Utah. Predictor variables comprised first or second degree relatives with stroke, hypertension, diabetes or hypercholesterolaemia. Outcome measures comprised diagnosis of MA, MO or CM according to the revised International Headache Society criteria. There was no significant difference in FH of vascular risk factors in MA compared to MO (adjusted OR 1.04, 95% CI 0.61-1.78). CM was associated with a decreased risk of FH of stroke (OR=0.11, 95% CI 0.02-0.87, p=0.036). There was no significant difference in FH of vascular risk factors in MA patients compared to MO. CM patients were more likely to have a negative FH of stroke compared to other headache types, suggesting that CM is likely a neuronal disease rather than a vascular one.

Stroke is a major public health burden worldwide. Prevention programme are essential to reduce the incidence of stroke and to prevent the all but inevitable stroke epidemic, which will hit our population (developing countries) hard as our population age and adopt lifestyle of the more developed countries. In this study we have tried to find the clinical characteristics of the stroke patients admitted in NMCTH and the commonest risk factors and its magnitude in our population. In these retrospective clinical case series study, we included the cases which were admitted in NMCTH over the past 2 years (from 1st April 2003 to 31st march 2005). All these patients were confirmed cases of stroke (CT scan was done in all these cases). Clinical profiles of all these patients were studied and analyzed using SPSS 11.0 version software. Seventy two patients were diagnosed as having cerebrovascular accident. The mean age of the patients having stroke in our study was 61 years. The commonest symptom was unable to move one side of the body (90.0%), other common symptoms were slurring of speech (33.0%), loss of consciousness (29.0%), headache (23.0%) and deviation of mouth (22.0%). 70 patients (97.0%) had 2 or more than 2 symptoms (i.e. multiple symptoms). Smoking (61.0%), hypertension (60.0%) and atrial fibrillation (8.0%) were the commonest modifiable risk factors, while increased age (mean 61 years) was the commonest nonmodifiable risk factor. Ischemic stroke (68.0%) was common than hemorrhagic (32.0%) stroke. In this study we found that smoking and hypertension was the commonest risk factor in our study group. Atrial fibrillation (8.0%) and diabetes mellitus (8.0%) were among the less common risk factors, whereas alcoholism and hypercholesterolemia were negligible in our study population. Multiple clinical features are common with unable to move the one side of the body being the commonest. The commonest form of stroke detected in our study group was ischemic type which is comparable to the study done in the past. Despite of these findings a bigger epidemiological study is needed to generalize this view over our community.

Case series have demonstrated an increased incidence of white matter lesions (WMLs) in patients with migraine. It is controversial whether the evidence of subclinical brain lesions relates to a higher risk of cerebrovascular disease. The objective of this study was to evaluate the association between magnetic resonance imaging (MRI) subclinical brain lesions and cerebrovascular risk factors (hyperhomocysteinaemia, MTHFR genotype, patent foramen ovale, hypertension, smoking and hypercholesterolaemia). From our database of 1201 patients followed at our Headache Clinic since September 2003 we analysed the MRI findings of 253 individuals. All MRI were blindly analysed by a second neuroradiologist (C.A.) and patients with WMLs (study group) were evaluated. In order to assess the association of WMLs with specific vascular risk factors, patients with WMLs were matched, according to age, sex and ICHD II diagnosis, with an equal number of individuals with normal MRI (control group). Headache was classified by the International Classification of Headache Disorders (ICHD 2004) criteria. We did not find any statistically significant difference between the two groups with regard to the presence of the cerebrovascular disease risk factors considered. Our results confirm that the WMLs are not related to the cerebrovascular disease risk factors.

Cerebral hyperperfusion syndrome is a rare but well-described complication following carotid endarterectomy or stenting. Clinical signs are ipsilateral, throbbing, unilateral headache with nausea or vomiting, seizures, and neurological deficits, with or without intracerebral abnormalities on CT scan, such as brain edema or intracerebral hemorrhage. Subarachnoidal hemorrhage is rarely described especially if it occurs isolated. We describe a 74-year-old man with a history of high blood pressure, hypercholesterolemia, atrioventricular block with pacemaker, and ischemic cardiopathy with coronary bypass. He underwent right carotid endarterectomy for a 90% NASCET asymptomatic stenosis. Four days after surgery, he complained of unusual headaches with right, throbbing hemicrania. Nine days after surgery, he presented with left hemiplegia and a partial motor seizure. He had fluctuant altered consciousness, left hemiplegia, and left visual and sensory neglect. Brain CT showed right frontal subarachnoidal hemorrhage without parenchymal bleeding. Cerebral angiography found no cerebral aneurysm, no vascular malformation, but a vasospasm of the left middle cerebral artery. Transcranial Doppler confirmed this vasospasm. Evolution was favorable with no recurrence of seizures but with an improvement of the neurological deficits and vasospasm. Physicians should bear in mind this very rare complication of endarterectomy and immediately perform neuroimaging in case of unusual headache following endarterectomy or angioplasty.

Use of all-transretinoic acid (ATRA) with other chemotherapeutic agents in the treatment of acute promyelocytic leukemia (APL) has been shown to cause the differentiation of abnormally granulated specific blast cells into mature granulocytes by acting on the t(15; 17) fusion gene product. The complete remission rate is increased and survival time is prolonged in APL patients who receive chemotherapy plus ATRA, whereas ATRA syndrome and other ATRA-related adverse effects including pseudo tumor cerebri, headache, severe bone pain, mucosal and skin dryness, hypercholesterolemia, and cheilitis may be observed especially during induction phase of the treatment. In this paper, we report a 9-year-old girl with APL who developed pancarditis while receiving the APL-93 treatment protocol. In our patient, endocarditis and myocarditis were initially determined after ATRA treatment during the induction part of the protocol. All findings disappeared after ATRA was discontinued. When ATRA was readministered in the maintenance part of the treatment protocol, she developed pancarditis and severe pulmonary edema. As her symptoms decreased dramatically with the discontinuation of ATRA and the initiation of steroid treatment, the clinical picture strongly suggested the ATRA treatment as the causative factor. To the best of our knowledge, this clinical picture of pancarditis secondary to ATRA treatment has not been reported earlier in the English literature.

Nephrotic syndrome (NS) is a renal disorder characterized by heavy proteinuria, hypoalbuninemia, edema and hypercholesterolemia. Nephrotic syndrome in children is known to be associated with an hypercoagulable state and thromboembolic complications. However cerebral sinovenous thrombosis (CSVT) is very rare. Here we report a seven-year-old child with steroid-dependent idopathic nephrotic syndrome resulting from a minimal change disease, developed multiple cerebral sinovenous thrombosis, presenting with headache, left sixth nerve palsy, and papilledema. The diagnosis of CSVT was established by cranial computed tomography, magnetic resonance imaging, and magnetic resonance angiography. He gradually recovered after anticoagulant therapy. CSVT is very rare in nephrotic children. The diagnosis of CSVT should be considered in any patient with nephrotic syndrome who develops neurologic symptoms. This report highlights the importance of suspecting and recognizing this potentially life threatening complication and initiating early treatment.

Results of an open multicenter prospective postmarketing observational program EKSPERT (post-marketing surveillance of the effectiveness and impact of the EKVATOR treatment on quality of life in patients with arterial hypertension in ambulatory practice). Observation of 10 000 patients conducted in 300 medical center in various regions of the Russian Federation in 1005 doctors. Selected for the final analysis 4954 registration cards. It is shown that in patients with initially insufficient effective antihypertensive treatment has a large number of risk factors: men older than 55 years--56.5%, women older than 65 years--27.8%, unfavorable family history of arterial hypertension (AH)--87.9%, diabetes mellitus (DM)--13.4%, smoking--of patients 18.6%, obesity--35%, angina--35.59%, heart failure--41.3% with a history of myocardial infarction--10.9%, stroke--4.5%, renal disease--11.8%, hypercholesterolemia > 5.0 mmol/l--76.7%. Initially drug antihypertensive treatment was performed in 76.6% of patients, while 43.9% were treated regularly. Prior studies angiotensin converting enzyme inhibitors (ACE) afforded 60.56%, sartans--11% of patients, beta-blockers--41.9%, duretics--41.46%, calcium antagonists used in 21.42% of the patients. After the cancellation of previously used other ACE inhibitors, calcium antagonists and sartans patients were switched to therapy with the EKVATOR (amlodipine and lisinopril). Intensity reduction in systolic and diastolic blood pressure (SBP and DBP) did not depend on sex of the patients, the presence of angina, diabetes. Greater reduction in blood pressure in hypertensive duration more than 5 years, in the presence of congestive heart failure due to more frequent initiation of therapy with full-dose combination (amlodipine 10 mg and lisinopril 20 mg). After 1 months of starting therapy changes uorvney target blood pressure (< 140 and 90 mmHg) reached 51.5% of patients. Target SBP reached 59.7% of patients, the target level of DBP--69.4%. It is important that the majority of patients crossed over lowti graduation SBP and DBP and significantly improved their quality of life assessment. Incidence of adverse events was low--1.5% of them are the most common were swelling in the legs, headache, dizziness, and dry cough. Replacing the previous therapy different ACE inhibitors, sartans and calcium antagonists to the fixed combination amlodipine and lisinopril) (drug EKVATOR), leads to a rapid, pronounced, and safe reduction of BP and improve health in the majority of patients with previously uncorrected BP.
