[Variations of blood pressure during the month of Ramadan].

The goal of this work is to study the consequences of the last on variations of the blood pressure (BP) in the course of 24 hours. From 1994 to 1997 we have selected 99 hypertensive patients and studied their BP profile. This study included 72 women and 27 men. Their age varies from 22 to 72 years (average 56.7 +/- 9 years). All these patients has an ambulatory blood pressure measurement (ABPM) before the fast and during Ramadan. Before Ramadan the period of the sleep goes from 10 pm +/- 1 h to 8 am +/- 1 h. During the month of Ramadan, the sleep lasts from 0 h +/- 1 to 9 am +/- 1 h. [table: see text] No statistically significant difference is noted between these 2 periods neither for the systolic BP (SBP) nor for the diastolic BP (DBP), for the BP of 24 hours, and the diurnal and nocturnal periods. We have then the compared the hourly average on 24 hours of the 99 patients. We observed that during the month of Ramadan the peak of the awakening is delayed by 2 hours and the nocturnal through is delayed by 1 hour. After this study, which is the first one to deal with variations of blood pressure during the fast of Ramadan we can confirm that in patients with essential hypertension without complications, the fast is well supported. The variations of BP are minimal and are related to the variations of the sleep, activity and eating pattern.

[Cardiac tamponade and transient ischemia revealing a syndrome of primary antiphospholipid antibodies].

The authors report a case of echocardiographically confirmed cardiac tamponade, which required emergency pericardial aspiration, and a transient ischaemic attack revealing an underlying primary antiphospholipid antibody syndrome in a 29-year-old patient. The test for antiphospholipid antibodies was positive on 2 occasions (IgG > 91.41 micrograms/l). The diagnosis of systemic lupus erythematosus was eliminated. A favourable course was observed after 3 months of corticosteroids and platelet antiaggregants. Any case of cardiac tamponade or transient ischaemic attack with an unexplained aetiology in a young patient must suggest the diagnosis of antiphospholipid antibody syndrome.

[Hypertension and Takayasu disease. Report of 8 cases].

In this paper, the authors report 8 cases of Takayasu disease presenting in the form of hypertension, observed in the Cardiology of Ibn Rochd University Hospital in Casablanca between 1983 and 1995. The majority of cases presented with renovascular HT, secondary to unilateral or bilateral renal artery stenosis. More rarely, the patients presented proximal hypertension secondary to coarctation of the aorta. Medical treatment was prescribed all 8 cases, associated with surgery in 8 cases.

[Approach of Moroccan cardiologists to arterial hypertension].

The authors conducted a survey among 300 cardiologists in order to evaluate their knowledge of HT. Most of the 200 cardiologists answering the survey considered that systolic HT was defined by a systolic blood pressure greater than 160 mmHg (75%). Only 14 cardiologists (7%), defined systolic HT as a blood pressure greater than 140 mmHg. 121 cardiologists (60.5%) defined diastolic HT as a pressure greater than 95 mmHg. 2/3 of cardiologists were not familiar with the conclusions of the JNCV for the detection, evaluation and treatment of HT. All cardiologists agreed that treatment of HT should start with single-agent therapy. In the case of insufficient control, 11% doubled the dose, 5% changed the drug in the same class, 53% changed therapeutic category and 30% prescribed two-agent therapy. Once BP was stabilized, one half of cardiologists reviewed their patients once every 3 months, and 22.5% reviewed their patients once every six months. These results demonstrate that cardiologists do not correctly follow the rules of management of HT recently defined by the various working parties. The authors propose a number of points to remedy some of the deficiencies revealed by this survey.

Pericardial tamponade as the first manifestation of dermatopolymyositis.

Pericardial involvement in polymyositis and dermatomyositis (PM/DM) is rare, usually asymptomatic and exceptionally part of the initial presentation. We describe a 37-year-old patient hospitalized for overt acute pericarditis, revealing dermatomyositis, which to our knowledge has not been previously reported. Pericardial puncture relieved the patient. The pericardial fluid was citrine yellow, exsudative, and mainly contained lymphocytes. Search for LE cells and anti-DNA antibodies was negative, whereas the antinuclear antibodies and the rheumatoid factor were present in the pericardial fluid. A biopsy of the pericardium showed a non-specific chronic inflammatory state and the search for an etiology was negative. There was no sign of tuberculosis, systemic lupus, nor neoplasia. Moreover bacteriological cultures and HIV serology were negative. After pericardiostomy associated with corticosteroid therapy at the dose of 1 mg/kg/day, outcome was good with a resolution of the pericarditis confirmed at one-year follow-up. Since pericardial tamponade, even though rare, may be fatal in a patient with dermatomyositis, we emphasize that a two dimensional echocardiographic study should be performed in all patient presenting with dermatopolymyositis.

[Deep venous thromboses and occult cancers].

The association between venous thrombosis and cancer has been known for a long time. Thrombophlebitis often occurs during the course of a known cancer, but sometimes constitutes the presenting sign. Based on a series of 10 cases of deep venous thrombosis (DVT) revealing an underlying cancer, the authors analyse the various aspects of this association and the elements which help to guide the diagnosis towards a cancer. A simple assessment comprising clinical examination, full blood count and differential white cell count, erythrocyte sedimentation rate, protein electrophoresis, chest x-ray and abdomino-pelvic ultrasonography was performed on admission in 75 cases of presumably idiopathic DVT and revealed a cancer in 10 cases: 6 women and 4 men with a mean age of 53 years. Cancers were located in the urogenital tract in 5 cases, in the bronchi in 2 cases, in the stomach in one case, and there was one case of acute myeloblastic leukaemia (AML) and another case of liposarcoma of the left iliac fossa. The histological type most frequently encountered was adenocarcinoma in 6 cases. In 9 out of 10 cases, the cancer was discovered at the stage of metastases. However, a localized cancer was detected in one case, in which surgical treatment allowed cure of the patient. Comparison of the various characteristics of DVT between the group of DVT revealing a cancer and the group of DVT which remained idiopathic did not reveal any statistically significant difference. A simple, inexpensive assessment looking for a cancer must be systematically performed in all cases of idiopathic DVT in patients between the ages of 50 and 85 years. Other more elaborate examinations may be requested on the basis of the results of the preliminary assessment.

[Heart failure and arterial hypertension disclosing amyloidosis].

Amyloidosis results from protein infiltration of the extracellular space of organs and tissues. Several amyloidosis proteins have been identified. Protein AL, (deriving from immunoglobulin light chain), protein AA and prealbumin are the most involved in this disease. When AL amyloidosis involves the heart, the illness is often terminal. Most clinical symptoms are heart failure and arrhythmia or block conduction. This case was characterised by the unusual combination of hypertension and amyloidosis. The diagnosis suggested by the echocardiographic but was confirmed by the damaged organ's biopsy. The present case concerns a young woman, who has hypertension and a pulmonary oedema. The echocardiographic scan showed a septal hypertrophy with a shining and granite-like aspect which is compatible with heart amyloidosis. Systolic and diastolic disorder with mitral and aortic regurgitation were also revealed. The kidney and rectum biopsies confirmed amyloidosis AL of the Kappa dysglobulinemia type, without extraosseous plasmocytoma. The heart and kidney failure symptoms disappeared after treatment with diuretics and ACE inhibitors.

[Blood pressure determination and medical competence].

Hypertension diagnosis depends closely to the blood pressure measurement. The aim of this work is to show whether blood pressure measurement should be done by a beginner or a competent doctor. The blood pressure of 180 patients, (150 females, 30 males) was taken by two physicians. The patients' average age was 51 +/- 11. One of the two physicians was a cardiologist who took all the patients blood pressure. Others where six doctors in training, that is sixth' year students at the faculty of medicine. They took part in this study for a week. The procedure was that the cardiologist and one of the training doctors took the patient's blood pressure at the same time after 15 min rest. We have calculated the average systolic blood pressure and diastolic blood pressure of 720 measures. Then the difference between the cardiologist's measures and those of all the training doctors. After that we have analysed the difference between the average of 120 measures taken by one of the training doctors and the corresponding measurement of the specialist. We have then compared the difference of the 20 measures of every day taken by the training doctor and the ones taken by the specialist. The difference wasn't statistically significant either for the systolic blood pressure or the diastolic blood pressurement. We have studied the evolution of the average of the 20 measurements of every day during the whole week. So, we have noticed that the difference lowers from the first days to the sixth. In the end, we were interested in the last figure of each measurement of blood pressure. The training doctor often gave measurements up to 0 or 5 whereas the specialist gave precise measurements. We have concluded from this work that if experience is needed, the physician has to know the principals and the tricks of blood pressurement. Moreover, the blood pressure variations by "white coat" effect can't be explained by measurements techniques. This effect can be considered as psychic, interactions between doctors and patients.

[Primary hyperaldosteronism. Apropos of 2 cases].

Primary hyperaldosteronism (PHA) represents less than 1 to 2% of all causes of hypertension (HT). We report 2 cases of primary hyperaldosteronism which emphasize the difficulty of distinguishing neoplastic PHA from idiopathic PHA, observed in a 60-year-old woman and a 42-year old woman, respectively. In both cases, the diagnosis of PHA was suggested by marked hypokalaemia with inappropriate potassium excretion and was confirmed by hyperaldosteronaemia and low and poorly stimulated renin activity. In the first case, computed tomography showed nodular hyperplasia of the 2 adrenal glands. The patient was treated with spironolactone and calcium channel blockers which controlled blood pressure and serum potassium. In the second case, computed tomography and magnetic resonance imaging revealed an adrenocortical adenoma confirmed by pathological examination after the operation. The diagnosis of primary hyperaldosteronism is based on three steps: detection, positive diagnosis and aetiological diagnosis. Detection is essentially based on demonstration of hypokalaemia. Positive diagnosis is based on demonstration of elevated aldosterone secretion with inhibited renin secretion. The aetiological diagnosis is dominated by the differentiation between Conn's adenoma and bilateral adrenal hyperplasia, which has therapeutic implications.

[Cardiac tamponade disclosing systemic lupus erythematosus].

Cardiac tamponade secondary to systemic lupus erythematosus is rare and has a very serious prognosis. The authors report a case of cardiac tamponade confirmed by echocardiography, which constituted the presenting sign of systemic lupus erythematosus in a 20-year-old patient, who required emergency pericardial aspiration. The diagnosis of systemic lupus erythematosus was established on the basis of the combination of pericardial involvement, non-erosive arthritis, leukopenia with lymphopenia, presence of LE cells and anti-native DNA antibodies and positive antinuclear antibody titre of 1/2560. The clinical course was favourable in response to 3 months of corticosteroid treatment. The possibility of SLE should be considered in any case of cardiac tamponade in a young patient in which the aetiology is not explained.

[Survey on the practice of antibiotic prophylaxis of infective endocarditis by dentists].

The authors undertook an enquiry among 287 dentists to assess their practice of prophylactic antibiotic therapy against infectious endocarditis. Of the 227 dentists who replied, most (90%) knew that a dental extraction required prophylactic antibiotic therapy. They correctly prescribed antibiotics to prosthetic valve patients (84%) and to those with post-rheumatic cardiac disease (87%). Many dentists considered that coronary bypass (66%), mitral valve prolapse without mitral regurgitation (65%) or chronic myocardial infarction (68%) also required antibiotic prophylaxis, contrary to published recommendations. Only 21% of dentists used the recommended 3 gram dose of amoxicillin; the others prescribed a lower dose or another antibiotic. Approximately half the dentists started treatment 1 to 3 days too soon and less than 5% used the recommended single dose of antibiotic. These results show that dentists do not adhere strictly to the rules of prophylaxis on infectious endocarditis defined by different working groups. The authors make several suggestions to improve the prevention of infectious endocarditis and to remedy the problems shown up by this study.

[Endomyocardial fibrosis of the right heart in Behçet disease].

Cardiac involvement is rare in Behçet's disease. Endomyocardial fibrosis of the right heart is exceptionally rare and is associated with right ventricular thrombosis. The authors report the case of a 27 year old man who died of a massive pulmonary embolism and who suffered from right-sided endomyocardial fibrosis with intraventricular thrombi. The diagnosis was made at autopsy. Behçet's disease was diagnosed on the finding of bipolar aphthous ulcers and skin hypersensitivity. The authors support previous workers in stating that Behçet's disease should be considered as a possible cause of endomyocardial fibrosis of the right heart.
