ABSTRACT
STUDY'S GOAL: Our goal is to enrich the medical literature by sharing our experience in managing a case of sub-acute upper limb ischemia that revealed Horton's disease. This is particularly relevant given the current lack of well-established guidelines. INTRODUCTION: Acute upper limb ischemia is rarely seen in Horton's disease. CASE REPORT: We present a case of a 63-year-old female patient with sub-acute ischemia in both upper limbs, accompanied by jaw claudication and absence of bilateral temporal pulses. The CT Angiography scan revealed bilateral occlusions and stenosis of the axillary and sub-clavier arteries, as well as involvement of the external carotid arteries and its branches. The Arteriography confirmed abnormalities in the medium-sized arteries of the supra-aortic trunks. The histopathology examination of the temporal artery biopsy was negative. The patient received emergency corticosteroid therapy followed by an immunosuppressant. Due to the improved clinical condition of the upper limbs, surgical intervention was not performed.

OBJECTIVES: To evaluate the prevalence and factors associated with Chronic psychiatric and somatic illness among medical students in Morocco. METHODS: A multicentric cross-sectional study during a period of four weeks in February 2019 involving 605 students of 1st, 2nd and 3rd cycle of medical studies of the faculties of medicine in Morocco. RESULTS: 41.5% (251) of students confirmed having a chronic disease, among which 80% were under treatment. Psychiatric conditions represented the most frequent chronic illnesses among medical students (28%), followed by dermatological (16%), allergic and respiratory (12.2%), and gastroenterological (11%) conditions. Chronic illnesses among medical students were significantly associated with female gender (P: 0.0000000037), level of education (P: 0.0000), personal history of suicide attempts (P: 0.0000259), and a consumption of psychoactive substances (P: 0.0000029046). CONCLUSION: Chronic illnesses are frequent, underestimated and undertreated among medical students in Morocco. The link with stress has been suggested as the value of establishing a program to train medical students in stress management.

Venous thromboembolism (VTE) is a common clinical problem that is associated with substantial morbidity and mortality. The aim of this study was to describe the clinical practices in VTE prophylaxis in university and peripheral hospitals in Morocco. This is a national, cross-sectional, multicenter, observational study assessing the management of the VTE risk in selected Moroccan hospitals (four university and three peripheral). The thromboembolic risk of the selected patients was assessed according to the American College of Chest Physicians (ACCP) guidelines (2008). We hypothesized that interventions for VTE guideline implementation in those hospitals may improve prophylaxis use for hospitalized patients. A total of 1318 patients were analyzed: 467 (35.5%) medical and 851 (64.5%) surgical. The mean age of patients was 52.6 ± 16.5 years, and 52.7% were female. A total of 51.1% patients were considered to be at risk of VTE according to ACCP guidelines and were eligible for thromboprophylaxis (TP). Medical patients were more likely to present risk factors than surgical patients (53.6 vs. 50.7%, respectively). TP was prescribed for 53.1% of these patients, 57.4% in at-risk surgical patients and 50.3% in at-risk medical patients. TP was also prescribed for 42.9% of non-at-risk patients. The concordance between the recommended and the prescribed prophylaxis was poor for the total population (kappa = 0.110). TP did not improve sufficiently in our hospitals, even after implementation of the guidelines. New strategies are required to appropriately address TP in hospitalized patients.

The antithyroid agents (carbimazole, methimazole, thiamazole, propylthiouracil and benzylthiouracile) are the drug class that is associated with a high risk of agranulocytosis. Acute and profound (<0.5×10(9)/L) isolated neutropenia occurring in a subject treated with antithyroid agents should be considered as a drug-induced agranulocytosis, until proven otherwise. The clinical spectrum ranges from discovery of acute severe but asymptomatic neutropenia, to isolated fever, localized infections (especially ear, nose and throat, or pulmonary) or septicemia. With an optimal management (discontinuation of antithyroid agents, antibiotics in the presence of fever or a documented infection, or use of hematopoietic growth factor) the current mortality is close to 2%.

INTRODUCTION: Hereditary hemorrhagic telangiectasia (HHT), is a rare, hereditary vascular dysplasia, characterized by recurrent epistaxis, mucocutaneous telangiectasias and visceral arteriovenous malformations. The vascular endothelial growth factor VEGF seems to play a crucial role in the pathogenesis of this disease. Recently bevacizumab, a humanized monoclonal VEGF inhibitor, has shown promise in treating patients with HHT. CASE REPORT: A 66-year-old man, having HHT since the age of 30 years with recurrent epistaxis related to telangiectasia at the nasal septum and chronic iron deficiency anemia requiring frequent blood transfusions with iron infusions. The assessment of his disease showed septal perforation, telangiectasis in the proximal jejunum and terminal ileum, and pulmonary arteriovenous malformations. There was no improvement, despite iron infusions, repeated blood transfusions and cauterization. The patient was treated with bevacizumab at a dose of 5mg/kg/infusion every 2 weeks and was given 6 cycles. Bevacizumab, was effective without side effects. DISCUSSION: It has been hypothesized that HHT is related to an imbalanced state between antiangiogenic factors and proangiogenic factors. Mutations of 3 genes are actually identified in HHT: ENG, ACVRL1, MADH4. The management of patients with HHT currently based on screening for visceral arteriovenous malformations and symptomatic measures are often disappointing. However, the angiogenic nature of this disease suggests an interesting therapy by using angiogenesis inhibitor. Therefore, bevacizumab was introduced as a potential therapy for HHT. Some clinical cases or small series report the efficacy of bevacizumab, in HHT with recurrent epistaxis, refractory iron deficiency anemia, gastrointestinal bleeding and also in liver vascular malformations with high cardiac output failure. CONCLUSION: The use of modulators of angiogenesis such as bevacizumab is a possible therapeutic target in HHT.

Hypercobalaminemia (high serum vitamin B12 levels) is a frequent and underestimated anomaly. Clinically, it can be paradoxically accompanied by signs of deficiency, reflecting a functional deficiency linked to qualitative abnormalities, which are related to defects in tissue uptake and action of vitamin B12. The aetiological profile of high serum cobalamin predominantly encompasses severe disease entities for which early diagnosis is critical for prognosis. These entities are essentially comprised of solid neoplasms, haematological malignancies and liver and kidney diseases. This review reflects the potential importance of the vitamin B12 assay as an early diagnostic marker of these diseases. A codified approach is needed to determine the potential indications of a search for high serum cobalamin and the practical clinical strategy to adopt upon discovery of elevated cobalamin levels. While low serum cobalamin levels do not necessarily imply deficiency, an abnormally high serum cobalamin level forms a warning sign requiring exclusion of a number of serious underlying pathologies. Functional cobalamin deficiency can thus occur at any serum level.

OBJECTIVE: The objective of this review is to evaluate the usefulness of oral cobalamin (vitamin B12) treatment. MATERIAL AND METHOD: PubMed was systematically searched for English and French articles published from January 1990 to January 2007. RESULTS: Prospective randomized studies (n = 3), a systematic review by the Cochrane group (n = 1) and prospective studies in well-determined population (n = 5) provide evidence that oral cyanocobalamin therapy may adequately treat cobalamin deficiency in elderly patients. However, the current literature may not suggest a strategy in terms of the form (hydroxy- or cyanocobalamin), frequency and duration of the treatment. CONCLUSION: This present review confirms the previously reported efficacy of oral cyanocobalamin treatment in elderly patients.

The location of bone histoplasmosis is rare. It is a parasitic infection caused by Histoplasma capsulatum, affecting especially the immunocompromised. Diagnosis is difficult, requiring the use of mycological and histopathological studies. Through this observation, we report a rare sequence of the development of sacrum histoplasmosis in a patient treated 10 years ago for a malignant non-Hodgkin lymphoma of the sacrum with complete remission. The clinical and radiological investigations suggested a lymphomatous relapse but the pathological study showed histoplasmosis. Antifungal treatment was started with an encouraging evolution.

Idiosyncratic drug-induced thrombocytopenia is a relatively rare and potentially serious side-effect in its moderate and profound forms (platelet count less than 100 x 10(9)L). It may be of central or peripheral mechanism, with consumption or immunological destruction. The main incriminated molecules are heparins, quinidine, sulfonamides and gold salts. Hemorrhagic manifestations are the rule and their severity is related to the level of thrombocytopenia and the involved molecule. Heparin-induced thrombocytopenia is more often associated with thrombotic events. Diagnosis relies on medical history and clinical criteria, which also establish the level of imputability. The role of serological tests is not yet clear but seems to be particularly interesting in difficult diagnostic situations and in heparin-induced thrombocytopenia. The treatment is based on the discontinuation of the incriminated drug and on supportive measures that depend on the severity of the clinical features.

The objective of this review was to evaluate oral cobalamin (vitamin B(12)) therapy in adult and elderly patients, from the perspective of a hematologist. PubMed was systematically searched for English and French articles published from January 1990 to January 2007. Data from our working group, the 'Groupe d'étude des carences en vitamine B(12)des Hôpitaux Universitaires de Strasbourg', have also been included. Several prospective studies in well-determined population (n = 4), prospective randomized studies (n = 3) and a systematic review by the Cochrane group (n = 1) provide evidence that oral cobalamin therapy may adequately treat cobalamin deficiency, particularly hematological abnormalities or manifestations. These studies suggest that at least 1000 microg/day of oral cyanocobalmin are needed for pernicious anemia and a mean daily dose of 250 microg for food-cobalamin malabsorption. This present review confirms the previously reported efficacy of oral cobalamin treatment in adult and elderly patients.

OBJECTIVE: the aim of this study is to determine the clinical characteristics of drug-induced agranulocytosis in rheumatology. PATIENTS AND METHOD: it is a retrospective monocentric study, including all cases of rheumatologic drug-induced agranulocytosis followed between January 1985 and December 2005. RESULTS: eight female and 4 men, mean age 62.5 years (range: 17-79), were included in the present study. The causative drugs were: anti-inflammatory agents (n=5, 41.6%), methotrexate (n=3, 25%), sulfasalazine (n=2, 16.6%), noramidopyrine (n=1) and dapsone (n=1). Main clinical features included infectious disorders in 9 cases (75%) with 4 cases of septicemia (33.3%) and 2 cases of septic shock (16.6%). The mean neutrophils count was 0.132 x 10(9)/L (range, 0-0.4). Outcome was favorable in 11 patients (91.6%). One patient died of septic complications. CONCLUSION: in rheumatology, drug-induced agranulocytosis is a rare but life-threatening disorder.

PURPOSE: The aim of this study is to report personal experience of pancytopenia related to low-dose methotrexate and to review the literature. METHODS: We included retrospectively all cases of pancytopenia related to low-dose methotrexate (<25 mg/week), followed between January 1997 and December 2006, in the university hospital of Strasbourg, France. RESULTS: Five women, mean age 75.6 years, were included in the present study. Clinical manifestations included: symptomatic anemia (n=4), infection (n=3) and hemorrhagic manifestations (n=2); one patient had no feature. Mean hemoglobin concentration was 8,8 g/dl; mean white cell and platelet counts were 1,500 /mm(3) and 16,000 /mm(3), respectively. Potential risk factors were identified in all patients: renal failure and low serum albumin levels (n=5), anti-inflammatory drug intake (n=2), folate deficiency (n=4) and cobalamin deficiency (n=1). One patient died of septic and hemorrhagic cerebral complications. CONCLUSION: Pancytopenia related to tow-dose methotrexate is a rare but life-threatening disorder. Search and prevention of potential risk factors are required in all patients; determination of MTHFR genotype may be of several interests as folate supplementation.

OBJECTIVES: To describe a case of Behcet's uveitis associated with Kaposi's sarcoma occurring simultaneously in a patient and to review the literature on iatrogenic Kaposi's sarcoma. METHODS: We describe the case of a 44-year-old Moroccan man, who developed a Kaposi's sarcoma 8 months after immunosuppressive therapy for ocular Behçet's disease. He was treated with corticosteroids and cyclophosphamide (Exdoxan, Baxter) pulse for 6 months followed by oral azathioprine (Imurel, Glaxo Smith Kline). Literature searches were performed on iatrogenic Kaposi's sarcoma and other cases of such association and the potential pathogenic mechanisms involved. RESULTS: Iatrogenic Kaposi's sarcoma is widely reported to develop after renal transplantation during immunosuppressive therapy. Less commonly, Kaposi's sarcoma occurs in patients receiving long-term corticosteroids or immunosuppressive therapy for rheumatic diseases. It is considered to be induced by activation of latent human herpes virus 8. To our knowledge, this is the second reported case of iatrogenic Kaposi's sarcoma in a patient with ocular Behçet's disease. Interferon-alpha is of value for patients with both conditions. CONCLUSION: This case report underscores the relationship between environmental and infectious factors, drug-induced immunosuppression, and the development of Kaposi's sarcoma.
