Quand référer aux urgences un patient présentant une elévation sévère de la pression artérielle [When should a patient with severe hypertension be referred to the emergency ward?].

When a severe elevation of blood pressure occurs in conjunction with failure of a target organ, immediate referral of the patient to hospital is an easy decision for the primary care physician. However, when severe elevation of blood pressure is observed in the absence of any significant symptom, it is a much more difficult decision to take. Indeed, if some clinical situations require an immediate and aggressive anti-hypertensive therapy, such a treatment can be clearly deleterious for a number of other cases. This paper attempts to clarify in which situations the primary care physician should refer hypertensive crisis to the emergency department.

Disseminated American muco-cutaneous leishmaniasis caused by Leishmania brasiliensis brasiliensis in a patient with AIDS: a case report

The authors report a case of culture-proven disseminated American muco-cutaneous leishmaniasis caused by Leishmania brasiliensis brasiliensis in an HIV positive patient. Lesions began in the oropharynx and nasal mucosa eventually spreading to much of the skin surface. The response to a short course of glucantime therapy was good.

Comment évaluer le risque oncologique d'un patient souffrant de dermatomyosite [Can we predict the risk of malignancy associated with dermatomyositis?]

Dermatomyositis (DM) and polymyositis (PM) are idiopathic inflammatory muscle diseases which remain a therapeutic challenge. The association between DM and malignancy is relatively well established while this relationship is weaker with PM. The clinical management and research for an occult malignancy as well as the follow-up of patients with DM or PM is a matter of debate. Herein we report a case of DM who, despite an extensive clinical, radiological and biological work-up developed an occult ovarian cancer 12 months after the initial diagnosis. This case report was used as support to review the actual expert recommendations for the search of an occult malignancy in presence of DM or PM.

Conjunctival intraepithelial neoplasia in a patient treated with tacrolimus after liver transplantation.

PURPOSE: To report a case of conjunctival intraepithelial neoplasia in a patient treated with tacrolimus after liver transplantation for hepatic carcinoma. METHODS: Description of the initial clinical presentation of a patient, tumor management, and 15-month follow-up. RESULTS: A 70-year-old man presented with a conjunctival intraepithelial neoplasia that developed on the site of a preexisting pterygium. After total surgical removal and additional application of mitomycin, local tumor control was achieved. CONCLUSIONS: We describe a case of intraepithelial conjunctival neoplasia in a patient treated with systemic tacrolimus. Local tumor control was achieved at 15 months after appropriate surgical management.

Isolation of Pseudomonas cepacia in cystic fibrosis patient

Pulmonary infection on cystic fibrosis (CF) patients are associated with a limited qualitative number of microorganisms. During the colonization process, Staphylococcus aureus usually preceedes Pseudomonas aeruginosa. This latter is at first non-mucoid, being replaced or associated to a mucoid morphotype which is rare in other diseases. In 1980, Pseudomonas cepacia appeared as an important agent in CF pulmonary infections with a mean frequency of about 6.1% isolations in different parts of the world. The primus colonization mainly occurs in the presence of pre-existent tissue lesions and the clinical progress of the disease is variable. In some patients it can be fulminant; in others it can cause a gradual and slow decrease in their pulmonary functions. The concern with this germ isolation is justified by its antibiotic multiple resistence and the possibility of direct transmission from a colonized patient to a non-colonized one. We reported the first case of P. cepacia infection in a CF patient in our area. The microbiological attendance to this patient had been made from 1986 to 1991 and the first positive culture appeared in 1988. The sensitivity profile showed that the primus colonization strain was sensitive to 9 of 17 tested antibiotics, however in the last culture the strain was resistent to all antibiotics. These data corroborate the need for monitoring the bacterial flora on CF patients respiratory system.

Task force IV: Clinical use of ambulatory blood pressure monitoring. Participants of the 1999 Consensus Conference on Ambulatory Blood Pressure Monitoring

OBJECTIVE: To reach a consensus on the clinical use of ambulatory blood pressure monitoring (ABPM). METHODS: A task force on the clinical use of ABPM wrote this overview in preparation for the Seventh International Consensus Conference (23-25 September 1999, Leuven, Belgium). This article was amended to account for opinions aired at the conference and to reflect the common ground reached in the discussions. POINTS OF CONSENSUS: The Riva Rocci/Korotkoff technique, although it is prone to error, is easy and cheap to perform and remains worldwide the standard procedure for measuring blood pressure. ABPM should be performed only with properly validated devices as an accessory to conventional measurement of blood pressure. Ambulatory recording of blood pressure requires considerable investment in equipment and training and its use for screening purposes cannot be recommended. ABPM is most useful for identifying patients with white-coat hypertension (WCH), also known as isolated clinic hypertension, which is arbitrarily defined as a clinic blood pressure of more than 140 mmHg systolic or 90 mmHg diastolic in a patient with daytime ambulatory blood pressure below 135 mmHg systolic and 85 mmHg diastolic. Some experts consider a daytime blood pressure below 130 mmHg systolic and 80 mmHg diastolic optimal. Whether WCH predisposes subjects to sustained hypertension remains debated. However, outcome is better correlated to the ambulatory blood pressure than it is to the conventional blood pressure. Antihypertensive drugs lower the clinic blood pressure in patients with WCH but not the ambulatory blood pressure, and also do not improve prognosis. Nevertheless, WCH should not be left unattended. If no previous cardiovascular complications are present, treatment could be limited to follow-up and hygienic measures, which should also account for risk factors other than hypertension. ABPM is superior to conventional measurement of blood pressure not only for selecting patients for antihypertensive drug treatment but also for assessing the effects both of non-pharmacological and of pharmacological therapy. The ambulatory blood pressure should be reduced by treatment to below the thresholds applied for diagnosing sustained hypertension. ABPM makes the diagnosis and treatment of nocturnal hypertension possible and is especially indicated for patients with borderline hypertension, the elderly, pregnant women, patients with treatment-resistant hypertension and patients with symptoms suggestive of hypotension. In centres with sufficient financial resources, ABPM could become part of the routine assessment of patients with clinic hypertension. For patients with WCH, it should be repeated at annual or 6-monthly intervals. Variation of blood pressure throughout the day can be monitored only by ABPM, but several advantages of the latter technique can also be obtained by self-measurement of blood pressure, a less expensive method that is probably better suited to primary practice and use in developing countries. CONCLUSIONS: ABPM or equivalent methods for tracing the white-coat effect should become part of the routine diagnostic and therapeutic procedures applied to treated and untreated patients with elevated clinic blood pressures. Results of long-term outcome trials should better establish the advantage of further integrating ABPM as an accessory to conventional sphygmomanometry into the routine care of hypertensive patients and should provide more definite information on the long-term cost-effectiveness. Because such trials are not likely to be funded by the pharmaceutical industry, governments and health insurance companies should take responsibility in this regard.

Le soignant face au patient lombalgique chronique: l'expérience clinique de l'Unité Rachis à l'Hôpital orthopédique [The health professional's approach to chronic lumbago: clinical experience at the Spinal Cord Unit at the orthopedic hospital]

The treatment of back pain patients refers to the biopsychosocial model of care. This model includes illness in patient's personal and relational life. In this context, it is not only the physical symptom of the patient which is focused but also his psychological distress often hidden by algic complain. Clinical interviews conducted with back pain patients have highlighted psychosocial aspects able to influence the relationship between health care user and provider. Taking account of psychosocial aspects implies an interdisciplinary approach that identify and assesses patients' needs through adequate tools. As a result, the different health care providers implied with back pain patients have to collaborate in a structured network.

Fatal myocardial infarction after lung resection in a patient with prophylactic preoperative coronary stenting.

In this report we present the case of a 77-yr-old man who underwent resection of the upper lobe of the left lung for a carcinoma, six weeks after percutaneous transluminal coronary angioplasty (PTCA) with stenting of the left anterior descending (LAD) and circumflex coronary arteries. Antiplatelet therapy with clopidogrel was interrupted two weeks before surgery to allow for epidural catheter placement and to minimize haemorrhage. The surgical procedure was uneventful. In the immediate postoperative period, however, the patient suffered severe myocardial ischaemia. Emergency coronary angiography showed complete thrombotic occlusion of the LAD stent. In spite of successful recanalization, reinfarction occurred and the patient died in cardiogenic shock. Prophylactic preoperative coronary stenting may put the patient at risk of stent thrombosis if surgery cannot be postponed for three months. In such cases, other strategies such as perioperative beta-blockade for preoperative cardiac management should be considered.

AA-amyloidosis caused by visceral leishmaniasis in a human immunodeficiency virus-infected patient.

AA-amyloidosis in the setting of chronic visceral leishmaniasis (VL) has been reported in animal models but documentation in humans is unavailable. Here, we report on a Portuguese man who in 1996 was diagnosed with both human immunodeficiency virus (HIV)-infection and VL. Antiretroviral treatment led to sustained suppression of HIV viremia but CD4+ lymphocytes rose from 8 to only 160 cells/mL. Several courses of antimony treatment did not prevent VL relapses. Renal failure developed in 2006 and renal biopsy revealed AA-amyloidosis. The patient had cryoglobulinemia and serum immune complexes containing antibodies directed against seven leishmanial antigens. Antimony plus amphotericin B, followed by oral miltefosine resulted in a sustained VL treatment response with elimination of circulating Leishmania infantum DNA and CD4+ recovery. The concomitant reduction of serum AA levels and disappearance of circulating leishmanial immune complexes suggests that prolonged VL may lead to AA-amyloidosis in immunocompromised humans.
