Status epilepticus in black African patients with hypertensive encephalopathy: a rare entity that must not be underrated.

The severity of a blood pressure spike is more closely associated with serious organ dysfunction, which can be life-threatening in the short term, than with the blood pressure level itself. A hypertensive emergency is defined as the presence of high blood pressure associated with acute organ dysfunction. The specific nature of high blood pressure in black patients may cause more frequent hypertensive emergencies. In this retrospective case study, we report our experience and highlight the specific prognosis for black African patients. We examined three patients, aged 27, 47, and 59 years, admitted to intensive care for a hypertensive emergency with neurological distress, and all in status epilepticus. Average blood pressure was 171 mm HG. Treatment included intubation, ventilation, and induction of a barbiturate coma, plus antihypertensive treatment. The outcome was favorable, with an average stay of 5 days. The frequency of hypertensive emergencies varies according to age, ethnic origin, and period studied. Black patients often suffer from more severe forms of high blood pressure, arising at an earlier age. Hypertensive encephalopathy can occur in patients with or without chronic hypertension. Without treatment, the encephalopathy induces a coma that can quickly become fatal. Its spontaneous course is catastrophic (10-20% survival at one year), but more favorable with adequate treatment (60-80% survival at five years).

[Study of echocardiographic parameters of rheumatoid arthritis black African without clinically evident cardiovascular manifestations: A cross-sectional study of 73 cases in Senegal]. / Étude des paramètres échocardiographiques de la polyarthrite rhumatoïde noire africaine asymptomatique au plan cardiovasculaire : étude transversale de 73 cas sénégalais.

INTRODUCTION: Research of cardiac involvement in patients with rheumatoid arthritis can prevent complications and place in a logical secondary prevention. The objective of this study was to investigate the echocardiographic parameters in a population of Senegalese patients with rheumatoid arthritis without clinically evident cardiovascular manifestations. PATIENTS AND METHOD: We conducted a descriptive cross-sectional study, which included prospectively from outpatients in the internal medicine department of university hospital center Aristide Le Dantec in Dakar, Senegal, with a diagnosis of rheumatoid arthritis without clinically evident cardiovascular disease. It focused on a sample of 73 patients of both sexes aged at least 18 years. Following clinical examination, we conducted laboratory tests (CRP, fibrinogen, ESR, rheumatoid factors: Latex and Waaler-Rose, anti-CCP, antinuclear factors and anti-ENA antibodies), ECG, echocardiography standard. Data were analyzed using a descriptive study of the different variables with the calculation of proportions for categorical variables, and the positional parameters and dispersion for quantitative variables. RESULTS: A total of 73 patients with rheumatoid arthritis without obvious cardiac events and meeting the criteria of definition of the ACR 1987 were included in the study. The mean age was 44.17±14.43 years with extremes of 18 and 75 years. The mean duration of RA was 5.93±4.78 years. The concept of family inflammatory arthritis was reported in 35.60% of cases and almost one in six patients had at least a factor of cardiovascular risk (16.96%). The abnormalities found in Doppler echocardiography were dominated by diastolic LV dysfunction (42.46%), increased left ventricular mass in 35.61%. Valvular leaks of variable grades were highlighted regarding all orifices but were rarely significant. CONCLUSION: The realization of echocardiography in patients with rheumatoid arthritis without clinically evident cardiovascular manifestations helps to highlight cardiovascular abnormalities related to the natural course of the disease.

Socio-demographic and clinical profile of chronic pain with neuropathic characteristics in sub-Saharan African elderly.

Data on characteristics of neuropathic pain (NP) in sub-Saharan Africa are scarce, especially in the elderly. We conducted this study to appreciate the socio-demographic and clinical profile of chronic pain (CP) with neuropathic characteristics in sub-Saharan African elderly with musculoskeletal pain. From January to December 2011, we performed a cross-sectional study in all Rheumatology outpatients over 60 years at the Center for Gerontology and Geriatrics, Dakar, Senegal. In this study, we included patients who experienced musculoskeletal pain for 3 months or longer (CP) and with a DN4 score ≥ 4 (NP). A complete clinical examination was performed to make the diagnosis of NP 'definite' or 'probable', and to identify the aetiologies of NP. During the study period, 698 outpatients were examined. There were 394 out of the 549 patients over 60 years who reported CP. Among them, 28 patients (7.1%) scored ≥4 on the DN4 questionnaire. Female patients, low educational attainment, manual professions, non-workers and diabetes were associated with NP (p < 0.05). The symptoms described by patients with NP, often intricate, were lumboradiculalgia (n = 9), cervico-brachial neuralgia (n = 3), polyneuropathy (n = 12) and mononeuropathy (n = 6). The presumed aetiologies in patients with NP were: chronic spine diseases (n = 14), painful diabetic peripheral neuropathy (n = 8), Sjögren's syndrome (n = 1), tarsal tunnel syndrome in rheumatoid arthritis (n = 1) and bone metastasis (n = 1). No aetiology was identified among three patients. Chronic spine diseases associated with radiculopathies and diabetic neuropathy are the main causes of NP, well detected by DN4 questionnaire and clinical examination in Senegalese sub-Saharan African elderly.

[Amyloidosis in sub-Saharan Africa]. / Les amyloses en Afrique subsaharienne.

Amyloidosis is a protein folding disorder in which normally soluble proteins are deposited extracellularly as insoluble fibrils. When stained with Congo red dye, it produces apple-green birefringence under polarized light. The main amyloid proteins are AL, AA, ATTR and Aß(2)-M. The incidence of amyloidosis in sub-Saharan Africa ranges from 0.28 to 0.57% in autopsy series. Secondary AA amyloidosis is the most frequent, found in 42 to 66% of amyloidoses. Chronic infections, especially tuberculosis, are the main cause. AL amyloidosis is found in 21 to 34% of amyloidosis cases, half of them due to myeloma. Other types of amyloidosis seem rare, but are probably underdiagnosed. The clinical presentation in sub-Saharan Africa is similar to that in Western series. Further experimental and clinical studies will allow a better assessment of the characteristics of amyloidosis in sub-Saharan Africa.

[Seroprevalence of HBsAgs in patients with rheumatoid arthiritis in a hospital setting in Senegal]. / Séroprévalence de l'antigène HBs au cours de la polyarthrite rhumatoïde en milieu hospitalier Sénégalais.

PURPOSE: Rheumatoid arthritis is the most common chronic inflammatory joint disease in adults. In Senegal, where biotherapy is unavailable, treatment of RA relies on a combination of glucocorticoids and disease-modifying antirheumatic drugs (DMARD). Since DMARD, particularly methotrexate, induce hepatotoxicity pretreatment assays of serum transaminase and albumin levels, as well as serological tests for the hepatitis B and C viruses is recommended. Hepatitis B virus (HBV) infection is endemic in Africa, particularly in Senegal. The purpose of this study was to assess the seroprevalence of the HBV surface antigen (HBsAg) for HBV in 258 patients with RA in Senegal as a basis for defining the least hepatotoxic DMARD for these patients and ensuring the most suitable monitoring. METHOD: This retrospective study was based on a review of the medical records of patients examined between January 2005 and December 2009 at the rheumatology outpatient clinic of the Aristide Le Dantec Teaching Hospital in Dakar, Senegal. All patients met the American College of Rheumatology criteria for RA. RESULTS: A total of 258 patients were tested for HBsAg. Tests were positive in 6 for a seroprevalence of 2.3%. All 6 positive patients were women with a mean age of 48.7 years (range, 16-79 years). Transaminase levels were normal in 5 patients. In the remaining patient, ASAT level elevation were twice normal and ALAT was normal. No patients had clinical evidence of liver disease. CONCLUSION: HBsAg seroprevalence in our population of patients with RA was lower than in the general population of Senegal: 2.3% versus 15%-18%. No evidence indicated that HBVinfection produced specific features in patients with RA. Based on these findings, widespread use of methotrexate in optimal dosages appears safe in patients with RA in Senegal. Treatment should be accompanied by careful attention to HBV prevention.

[Systemic vasculitis: study of 27 cases in Senegal]. / Vascularites systémiques: 27 observations au Sénégal.

Studies on vasculitis in black Africa are rare. The purpose of this report is to describe a retrospective study of systemic vasculitis managed in the internal medicine, ORL and cardiolology departments of the Aristide le Dantec University Hospital in Dakar, Senegal from 1995 to 2007. A series of 27 cases involving 7 men and 20 women with a mean age of 49 years was compiled. Primary vasculitis included Horton disease in 3 cases, Wegener disease in 2, Takayasu disease in 1, and Buerger disease in 1. Secondary vasculitis included mixed cryoglobulinemia with Gougerot Sjögren syndrome in 7 cases, primary Goujeröt syndrome in 4, rheumatoid arthritis in 3, nodosa periarteritis with hepatitis B in 2, SHARP syndrome in 1, and polymyositis in 1. The remaining two cases involved abdominal periaortitis including one associated with retrosperitoneal fibrosis and tuberculosis and the other with spondylarthropathy. Corticotherapy in combination with anticoagulants, immunosuppressive therapy, and surgery, when necessary, allowed effective management in 24 cases. The findings of this study show that systemic vasculitis can have numerous etiologies and indicate that secondary forms are the most common. Appropriate care modalities are needed to prevent severe outcome in Senegalese hospitals.

[Tuberculosis and systemic diseases: study of 8 Senegalese cases]. / Tuberculose et maladies systémiques: Etude de 8 cas sénégalais.

PATIENTS AND METHODS: A retrospective study (2000-2007) of the tuberculosis observations during systemic diseases was conducted in the service of Internal Medicine of hospital Aristide Le Dantec of Dakar. RESULTS: 8 (4 men and 4 women) has been received. The mean age was 54.5 years. The localization of tuberculosis was lung (n=8) with pleurisy (n=2), ganglionic (n=1), vertebral (n=1) and an abscess of the psoas (n=1). The diagnosis of tuberculosis had been carried with the bacteriological analysis of the expectorations (n=7), the histology (n=1). The systemic diseases was: rheumatoid arthritis and Sjögren's syndrome (n=3), primary Sjögren's syndrome (n=4), autoimmune thrombopenia (n=1). The diagnosis of systemic diseases was previous to that of tuberculosis in 7 cases and concomitant in 1 cases. Under chemotherapy and corticosteroid therapy, the evolution was favorable in 6 patients. CONCLUSION: our study confirms the frequently character spread by the tuberculosis in patients affected by systemic diseases. This association enhances diagnostic and therapeutic problems.

Profil etiologique des adenopathies cervicales en medecine interne : etude de 66 observations

Les adenopathies cervicales sont un motif frequent d'hospitalisation en Medecine Interne. Elles peuvent etre le temoin d'une affection severe necessitant un diagnostic precoce. Nous avons etudie les aspects cliniques et l'apport diagnostique des examens paracliniques en particulier de la biopsie ganglionnaire au cours des adenopathies cervicales en Medecine Interne au Senegal. Il s'agissait d'une etude retrospective sur une periode de cinq ans et huit mois allant du 1er janvier 2000 au 20 a out 2006 dans le service de Medecine Interne de l'hopital Aristide Le Dantec de Dakar. Soixante six dossiers sur les 8610 dossiers de patients hospitalises ont ete colliges. Un questionnaire structure avait permis de recueillir les caracteristiques sociodemographiques; cliniques et paracliniques. Les adenopathies cervicales etaient retrouvees chez 37 hommes (57) et 29 femmes (44); soit un sex-ratio de 1;2. L'age moyen etait de 34 ans avec des extremes de 15 et 73 ans. La region cervicale laterale etait le site privilegie des adenopathies; suivie du cercle peri-cervical et de la region cervicale anterieure. Trente six patients presentaient des adenopathies superficielles d'autres localisations : axillaire (39); inguinale (32) et epitrochleenne (1;5). Les etiologies d'adenopathies cervicales comportaient aussi bien la tuberculose; principale cause en milieu tropical; les lymphomes tres souvent responsables demacro- adenopathies; que certains cas anecdotiques comme le syndrome de Rosai Dorfman Destombes

[Etiologic profile of cervical adenopathology observed in an internal medicine department in Dakar, Senegal. A 66 case series]. / Profil étiologique des adénopathies cervicales en médecine interne: étude de 66 observations à Dakar (Sénégal).

Cervical adenopathy is a frequent reason for hospitalization in the internal medicine department. This finding can be a sign of severe disorder requiring early diagnosis. The purpose of this retrospective study was to describe clinical features and evaluate diagnostic tests especially lymph node biopsy associated with evaluation of patients presenting cervical adenopathies in an internal medicine department in Senegal. Records of a total of 8610 patients treated in the Internal Medicine Department of the Aristide Le Dantec Hospital of Dakar, Senegal over a 68-month period from January 1, 2000 to August 20, 2006 were reviewed. Sixty-six files were included for study. A structured questionnaire was used to collect sociodemographic, clinical and paraclinic data. There were 37 men and 29 women. Average patient age was 34 years (range, 15 to 73 years). The side of the neck was the most frequent location of adenopathy followed by the pericervical arterial circle and anterior cervical area. Thirty-six patients presented superficial adenopathy in other locations including the armpit (39%), groin (32%) and elbow (1.5%). The etiologies underlying cervical adenopathy included classic causes such as tuberculosis that is the main cause in tropical regions and lymphoma that frequently led to macroadenopathy as well as novel causes such as Rosaï Dorfman Destombes syndrome.

[Monoclonal gammapathy of undetermined significance and autoimmune disease: description of three cases in Senegal]. / Gammapathies monoclonales de signification indéterminée et maladies auto-immunes: étude de trois observations sénégalaises.

Monoclonal gammapathy of undetermined significance (MGUS) has rarely been reported in African literature. The purpose of this article is to describe 3 cases of MGUS observed in women aged 63, 54, and 44 years in Senegal. All three patients had previously documented autoimmune disease, i.e., auto-immune thrombopenia, multiple auto-immune disease (comprising Sjögren's syndrome, polymyositis and vitiligo), and Sjögren's syndrome. Diagnosis of MGUS was made thanks to routine protein electrophoresis that demonstrated a monoclonal peak in the gammaglobulin area in all patients. Serum protein binding showed the IgG lambda subtype in one case and IgG kappa subtype in two cases. Medullogram findings were unremarkable with nondystrophic plasma cell rates ranging from 1 to 4%. Bisphophonate therapy was undertaken along with the recommended treatments for the associated autoimmune diseases, i.e., prednisone, hydroxychloroquine, and methotrexate. Treatment was successful in all three patients with stabilization of the associated diseases and of the monoclonal peak on subsequent electrophoresis. As of this writing, the mean duration of follow-up was 3 years. MGUS that has been uncommon in the African hospital setting should be screened for in all older patients or in patients presenting infection (especially due to virus) or autoimmune disease (as in the three cases presented herein). More systematic use of serum protein electrophoresis should reveal an increased incidence of MGUS. Diagnosis of MGUS requires regular clinical and laboratory surveillance due to the risk for complications of malignant hemopathies, especially multiple myeloma.

[Destombes Rosaï Dorfman syndrome: description of one case and diagnostic challenges in the tropical setting]. / Syndrome de Rosaï Dorfman Destombes à propos d'une observation: difficultés diagnostiques en milieu tropical.

Destombes Rosaï Dorfman (DRD) syndrome is form of nonlangerhans cell sinus histiocytosis. The main symptoms are cervical adenopathy, fever and fluctuating hepatosplenomegaly. It can be confused with ganglionary tuberculosis especially in our region where tuberculosis is common. This report describes a case of Destombes Rosaï Dorfman syndrome in a 40-year-old woman from Senegal. The main presenting symptom was the presence of massive tumour-like lesions on the neck with altered general condition and fever. Based on these clinical findings, ganglionary tuberculosis was suspected and presumptive treatment was initiated in the local hospital. However further workup failed to confirm the diagnosis and the patient was transferred to the Internal Medicine Department. Clinical examination in our service revealed the presence of extensive adenopathy in the supraclavicular, axillary, and inguinal regions. Laboratory tests demonstrated a nonspecific inflammatory syndrome. Abdominal ultrasonography depicted extensive mesenteric and para-aortic adenopathy. Chest x-ray showed bilateral and asymmetric mediastinal adenopathy. Medullogram findings were normal. Histology confirmed DRD syndrome. DRD syndrome is rare disease of unknown aetiology. In tropical areas differential diagnosis with ganglionary tuberculosis, lymphoma, and reactive hemophagocytic syndrome can be challenging. Lymph node biopsy should be performed in all patients presenting fever and polyadenopathy.

[Undesirable effects of methothrexate during treatment of rheumatoid arthritis]. / Tolerance du méthotrexate dans le traitement de lapolyarthrite rhumatoïde.

INTRODUCTION: Methotrexate used as antimetabolite since 40 years in cancerology, is curretly pointed out at weak dose in the treatment of rheumatoid arthitis. However, the intervening of undesirable effects is currently the principal factor limiting its use. The main of our study was evaluate the nature and the frequency of undesirable effects during treatement of rhumatoid arthritis by methotrexate in a prospective study in the department of internal medecine of A.L.D hospital. MATERIAL AND METHODS: Fifty patients were included in the study, they were 43 female and 7 male (sex ratio of 0.161).The mean age were 40.8 years, ranging from 18 to 68. The mean last of MTX treatment was 16.58 months, ranging from 1 to 64. RESULTS: Twenty seven patients (54%) had at least one undesirable effect. Undesirable effect appeared early in 74.1%. they were 61.5% when MTX was associated with others drugs versus 27.3% when MTX was used alone. Undesirable effects mostly were digestives (38%), general (30%), mucouscutaneous (8%) and hepatics (2%).for patients undesirable effects had involved. They were responsable of definitive stopping treatment in two cases of pulmonary tuberculosis.

[Clinical and endoscopic features of solitary rectal ulcer syndrom in the digestive endoscopy unit of Hospital Aristide Le Dantec in Dakar]. / Aspects cliniques et endoscopiques du syndrome de l'ulcère solitaire du Rectum dans l'unité d'endoscopie digestive du CHU A. Le Dantec de Dakar: à propos de 11 cas.

INTRODUCTION: The solitary rectal ulcer syndrome is a rare disease. In Africa only few studies have been held on this subject. The aim of this study was to determine the epidemiological, clinical and endoscopic aspects of this syndrome in the digestive endoscopy unit of hospital Aristide Le Dantec in Dakar. PATIENTS AND METHOD: It was a retrospective study based on all the cases of solitary rectal ulcer regarding to the conclusion of endoscopic examination from January 1994 to June 2002. All the patients without histological confirmation were excluded. RESULTS: We had recruited 11 cases among 4250 endoscopic exam (0.26 %). The mean age was 40 years (extreme 23 to 63 years). Female to male ratio was 1.75 with 4 males and 7 females patients. The main indications of endoscopic examination were frequently associated and were dominated by intermittent bleeding (8 cases) chronic constipation (6 cases) and false chronic diarrhea with muco hemorrhagic discharge (4 cases). The mean duration of the symptoms was 5 years. Ulcers were ovoid or circular. Their mean diameter was 8 mm and they were located 8 cm above the anal margin. The lesion was unique in 55 % of the cases and concerned the anterior wall of the rectum in 74% of the cases. There was an internal rectal prolapse in 54% of the cases. CONCLUSION: The solitary rectal ulcer syndrome is not frequent in the endoscopy unit of hospital Aristide Le Dantec in Dakar. It affects mostly young adult female. The symptoms are chronic and non specific. In tropical areas the disease is frequently misdiagnosed as colic amoebiasis.

[Diffuse infiltrative lymphocytosis syndrome (DILS) associated with HIV-1 infection: first Senegalese case report]. / Syndrome d'infiltration lymphocytaire diffuse ou DILS associé a une infection par le VIH -1: premier cas Sénégalais.

INTRODUCTION: The "Diffuse Infiltrative Lymphocytosis Syndrome" [DILS] is a seldom complication and even very particular case of HIV-1 infection, characterized by a merely syndrome and a systemic symptomatology superimposable to the figure met during the Gougerot-Sjögren Syndrome. GSS is nevertheless underlied by a lymphocyte infiltrate composed mainly of TCD8+ lymphocytes, while in the Gougerot-Sjögren syndrome (GSS), the lymphocyte infiltrate is essentially composed of TCD4+ lymphocytes. Despite the antiquity and significance of the HIV/AIDS pandemic, the DILS is not according to our knowledge individualized in the African literature. OBSERVATION: We are reporting a case revealed by a polyarthritis associated among others with a merely syndrome and a HIV-1 infection in a 32 years old Senegalese patient. Her CD4 rate was 327/mm3 and her viral load 17052. The biopsy of the accessory salivary glands showed a 4 grade lymphocite sialoadenitis according to Chisholm classification. The investigation of rheumatoid factors et anti-nuclear antibodies was negative. Under prednisone, hydroxychloroquine, methotrexate and tritherapy treatment, the evolution was favourable with a current return of 2 years. The rarity of DILS has pushed us to study its epidemiological, clinical, paraclinical, physiopathological and therapeutical aspects.

[Pulmonary hypertension revealing systemic diseases: two Senegalese case reports]. / Hypertension arterielle pulmonaire revelant des connectivites: a propos de deux observations Senegalaises.

INTRODUCTION: Pulmonary hypertension (PH) is a complication of autoimmune diseases which worsen the prognosis. In Senegal, a few cases of PH have been previously reported in patients with systemic sclerosis. CASE REPORTS: We report two cases of patients with PH that revealed autoimmune diseases (Sharp' syndrome and Sjögren syndrome). Epidemiological, clinical, evolutive and laboratory data were analyzed. Evolution of disease was favourable for one patient and fatal for the other. CONCLUSION: These two cases show necessity of early diagnosis of systemic diseases in our countries. PH should be screened in each patient with autoimmune disease before installation of irreversible pulmonary arterial lesions that respond to treatment. New therapy used in idiopathic PH are not yet accessible for our patients.

[Still disease in adult: a Senegalese case report]. / Maladie de still de l'adulte: etude d'un cas Sénégalais.

INTRODUCTION: The adult Still's disease is a systematic disease rarely reported in the black Africans. We are reporting a case characterized among other difficulties by its diagnostic difficulties. OBSERVATION: It is about a 29 years old black Senegalese woman patient, without particular antecedents, which presented a systematic chronic syndrome composed of a pharyngitis, a polyarthritis and general symptoms (fever, chills, sweats, change of the general state), a cutaneous eruption, a polyadenopathy, a hepatosplenomegaly. The biological analyses showed among others, an inflammatory syndrome (VS at 115 mm in the 1st hour, CRP at 100 mg/L, WBC at 10,400/mm3 with neutrophilia), a hyperferritinemia in 643 ng/l with collapse of the glycosylated ferritin at 13% (N between 60 in 80%). After elimination of any autoimmune or neoplastic suppurative infectious pathology in the decline of a check up as exhaustive as possible, the diagnosis of a Still disease in adult had been retained. Their was improvement under the combination of prednisone and methotrexate. CONCLUSION: Although it is exceptional in black African, this pathology shall be however part of the differential diagnoses of any unexplained systematic sign. The dosage of the ferritinemia and its glycosylated fraction as well as the resort to the criteria of Yamaguchi and Fautrel's classification of Still Disease in Adult shall allow to establish more prematurely the diagnosis of this potentially severe affection.

Tolerance du methotrexate dans le traitement de la polyarthrite rhumatoide

Introduction : Le methotrexate (MTX) utilise comme antimetabolite depuis pres de 40 ans en cancerologie; est actuellement indique a faible dose dans le traitement de fond de la PR. Cependant; la survenue d'effets indesirables est actuellement le principal facteur limitant son utilisation. Les objectifs de notre travail etaient d'evaluer la nature et la frequence des effets indesirables au cours du traitement de la PR par le MTX a partir d'une etude prospective en Medecine Interne. Materiels et methodes : Cinquante patients ont ete colliges dont 43 femmes et 7 hommes soit un sex-ratio de 0;161. L'age moyen etait de 40;8 ans; extremes (18-68). La duree moyenne du traitement au MTX etait de 16;58 mois; extremes (1-64). Resultats : Vingt sept patients soit 54ont presente au moins un effet indesirable. Ces effets indesirables etaient digestifs (38); d'ordre general (30); cutaneo-muqueux (8) et hepatiques (2). Ces effets secondaires ont persiste chez 19 patients; et ont ete responsable d'arret du traitement : provisoire chez 7 patients et definitifs chez 2 autres qui presentaient une tuberculose pulmonaire

Resultats : parmi les 4250 patients ayant eu des endoscopies; 11 avaient un ulcere solitaire du rectum (soit une frequence de 0;26). Leur age moyen etait de 40 ans (extremes a 23 et 63 ans) et le sex-ratio de 0;57 (4 hommes et 7 femmes). Les indications de l'endoscopie etaient souvent associees et dominees par les rectorragies intermittentes (8 cas); la constipation chronique (6 cas) et la fausse diarrhee chronique glairo-sanglante (4 cas). La duree d'evolution des symptomes avant le diagnostic etait en moyenne de 5 ans. La lesion ulcereuse etait ovalaire ou ronde avec un diametre moyen de 8 millimetres et elle siegeait en moyenne a 8 centimetres de la marge anale. Il s'agissait d'une lesion unique dans 55des cas et la face anterieure du rectum etait interessee dans 74des cas. Un prolapsus rectal interne etait associe chez 6 patients (54des cas). Conclusion : l'ulcere solitaire du rectum est rare dans l'unite d'endoscopie digestive du CHU Aristide Le Dantec de Dakar. Il atteint souvent l'adulte jeune de sexe feminin. La symptomatologie marquee par les rectorragies et les selles glairo-sanglantes; prete souvent confusion avec l'amibiase intestinale en zone tropicale

[Diagnostic and therapeutic features of tuberculosis in patients undergoing maintenance hemodialysis in Dakar]. / Caractéristiques diagnostiques et thérapeutiques de la tuberculose chez les hémodialysés chroniques à Dakar.

Tuberculosis in patients undergoing maintenance hemodialysis therapy presents a number of diagnostic and therapeutic challenges. This study was designed to assess the specific diagnostic and therapeutic features of dialysis-associated tuberculosis in a clinical setting. A total of 55 patients were enrolled in this retrospective study over the 5-year period from 1996 to 2000. Diagnostic techniques included questionnaire, clinical examination, chest X- ray, tuberculin skin test, Mycobacterium tuberculosis (MT) screening on biological fluids and tissue biopsy. Tuberculosis was diagnosed in 6 patients (11%). The disease occurred within the first two years after the beginning of hemodialysis. Initial signs were nonspecific, i.e., fever, weight loss, and cough. Tuberculin skin testing was negative in 5 cases. Tuberculosis was located in the lung in 2 cases, pleura in 2 cases, peritoneum in 1, and lymph node in 1. Isolation of the MT and confirmation by tissue biopsy was performed in only one case. Appropriate polychemotherapy was successful in 5 of 6 cases. Morbidity and mortality of tuberculosis in dialysis patients is closely related to early detection and treatment. Therapy is often based on strong presumptive evidence without definitive diagnosis.
