Open Journal of Nephrology (OJNeph) , 2015, DOI: 10.4236/ojneph.2015.51002
Aim: To study the functional dyspepsia in chronic hemodialysis patients of CNHU-HKM of Cotonou. Methods: This descriptive, analytical and cross-sectional study ran from 1 September 2013 to 28 February 2014 in the University Clinic of Nephrology Dialysis of CNHU-HKM of Cotonou. It included all chronic renal failure patients on hemodialysis for at least 9 months prior to the survey. After identifying the patients with upper gastrointestinal disorders, we had submitted to clinical Rome III criteria for functional dyspepsia. Upper endoscopy was performed in patients with clinical criteria of functional dyspepsia. Clinical factors associated, paraclinical and therapeutic were sought by logistic regression in univariate analysis. Data were analyzed using EPI DATA version 3.1. Results: 1) One hundred and thirty-one haemodialysis patients had participated in the study (sex ratio: 1.5, average age 49.6 ± 12.4 years). 2) The prevalence was 71.8% for upper gastrointestinal disorders, 64.9% for dyspeptic syndrome and 1.5% for functional dyspepsia. 3) They were associated to clinical criteria of functional dyspepsia of Roma III, the presence of high blood pressure, hypocalcaemia, treatment with calcic inhibitors and iron supplementation. Conclusion: Functional dyspepsia is uncommon in hemodialysis. The search of an organic cause is imperative for every dyspepsia.

Abstract: Introduction: Emphysematous pyelonephritis (EPN) is a severe, life-threatening infection of the renal parenchyma. This condition is characterized by the production of intrarenal and perinephric gas. In the world, the EPN is currently limited to case series reported. No cases have been described in black Africa. Aims: Related a first case of EPN diagnosed and treated in the University Hospital Center Sylvanus Olympio of Lomé in Togo. Observation: A 40 years old woman, with antecedent of diabetes presented pyelonephritis emphysematous class 2. She was treated successfully with antibiotic alone without using percutaneous drainage or nephrectomy. Conclusion: As reported in every case series, it was a young diabetic patient with a clinical features of acute pyelonephritis which CT scan had helped lay the EPN class 2

Abstract: Introduction: Viral hepatitis B (VHB) is a serious and global public health issue, particularly in sub-Saharan Africa where it is endemic. The objective of this work was to evaluate the effectiveness and safety of tenofovir disoproxil fumarate (TDF) in the treatment of chronic VHB in Cotonou. Methods: This was a descriptive cross-sectional study with a retrospective collection of data from January 1st, 2015 to December 31st, 2016 (24 months) and prospective from May to August 2017 (4 months). Chronic VHB patients treated with TDF for at least 6 months were included. The non-detectability of HBV DNA and the normalization of aminotransferases defined the virological and biochemical responses, respectively. The evaluation of the treatment response on liver fibrosis was done by using APRI score. Renal impairment was assessed by a reduction in glomerular filtration rate according to MDRD (Modifications of the Diet in Renal Disease) formula below 90 mL/min/1.73 m2. Results: In all, 42 patients treated with TDF were included. The average age was 46.7 ± 13.8 years. The study population was predominantly male with a sex ratio of 2.5. Among the 42 patients treated with TDF for an average of 60 weeks (24 to 96 weeks), 36 patients (85.7%) had a virological response; 21 patients (50%) had a biochemical response. Virologic response was 70% at week 24 (W24), 92.6% at W48, 87.5% at W72 and 100% at W96 without significant difference between W24 and W48; between W48 and W72 then between W72 and W96. There was a regression of fibrosis and cirrhosis but not significantly. Renal involvement occurred in 3 out of 19 cases (15.8%) including a case of chronic end stage renal failure and 2 cases of mild chronic renal failure. Conclusion: The treatment with TDF is effective and globally safe in our patients with chronic viral hepatitis B in Cotonou.

Introduction: General physicians can play an important role in the early detection of diabetic nephropathy (DN). Purpose: To assess the levels of general physicians’ knowledge, attitude and practice in terms of early detection of DN in Cotonou. Method: It was a cross-sectional, analytical and descriptive study which was conducted from 1st March 2015 to 30th September 2015. Every general physician working in a health structure in Cotonou who consented to participate in the study was included. We did not included medical specialists and general physicians working in nephrology department. Data were collected through a survey form designed with a score to assess the various items such as: knowledge, attitude and practice. The significance threshold is set to below 0.05. Results: In total, 202 general physicians were included. The average age was 30.9 ± 6.9 years ranging from 24 to 68 years. A male predominance was observed with 2.2 sex ratio. The majority of respondent medical physicians had poor knowledge in 76.2% cases, bad attitudes (61%) and bad practices (64.9%) in terms of early detection of diabetic nephropathy. There was positive impact of continuing medical training focused on diabetic nephropathy on attitudes (p = 0.016) and practices (p = 0.001) of these physicians. Conclusion: Diabetic nephropathy requires particular attention. General physicians’ continuous training is a principal solution.

Abstract: Objectives: To determine the prevalence and risk factors of erectile dysfunction (ED) in men on hemodialysis in Togo. Methods: Prospective cross-sectional study, descriptive and analytical ranging from December 2015 to February 2016 in the hemodialysis unit of CHU SO, only dialysis center in the country. The evaluation of the ED was made through IIEF-5 questionnaire. Results: 39 men (67.2%) of 58 hemodialysis is a sex ratio M/F of 2.05. The average age was 43.5 years with extremes of 25 and 59 years. The majority of men had a profession in 19 cases (48.7%). The mean duration of dialysis was 30 months with a range of 4 months and 90 months. Initial glomerular nephropathy was in 19 cases (48.7%) and vascular in 14 cases (35.9%). 38 patients were hypertensive (97.4%) and 6 diabetic men (15.4%). The prevalence of ED was 74.3% (29 cases). ED score was less than 10 points in 14 cases (35.9%); 01 case (2.6%) between 11 and 16 points; 06 cases (15.4%) between 17 to 21 points; 08 cases (20.5%) between 22 and 25 points; and 10 cases (25.6%) between 26 and 30 points. Age, profession and duration of dialysis were risk factors associated with ED (P <

Abstract: Objective: To describe clinical, biological and evolutionary profile of Acute Kidney Injury (AKI) due to Severe Malaria in the pediatric department. Methodology: This was a retrospective descriptive study that took place from January to December 2012. It has been included children aged 0 - 15 years admitted for severe malaria with positive thick drop. AKI was defined by using the modified RIFLE (Risk Injury Failure Loss End stage) classification for Pediatrics. Results: 338 children admitted for severe malaria were included. AKI was diagnosed in 24 children, a prevalence of 7.1% according to pRIFLE classification: RISK in 10 (3%), INJURY in 9 (2.6%) and FAILURE in 5 (1.5%). The average age was 8.16 ± 4.2 years. Clinical features were dominated by hemoglobinuria in 87.5%, oliguria, vomiting and fever in 75%. The biological features were dominated by severe anemia (Hb < 6 g/dl) in 79.2% of cases. Hyperkalemia (K > 5.5 mmol/l) was found in 2 cases. The mean parasitic density was 22,120 trophozoites. Malaria was treated primarily with artemether in 83.3% of the cases. Dialysis was indicated in 2 cases for menacing hyperkalaemia, but was not done because of lack of financial means. In one case, hyperkalaemia was successfully treated with symptomatic measures, but in the second case, these measures were not allowed to normalize kalaemia, and death occurred. Conclusion: Acute post-malarial renal failure secondary to tubular necrosis may be the dominant clinical features of severe malaria. Death may occur. Preventing malaria would be the best way to avoid it.

Introduction: The objectives of this work were to assess haemodialytic patients’ quality of life (QoL) and to identify factors affecting this QoL. Patients and Methods: It was a three (03) month monocentric and transversal study (from October 24, 2011 to January 27, 2012) conducted in the haemodialysis unit at Hubert Koutoukou Maga Teaching Hospital (CNHU-HKM) in Cotonou. Patients included were residents of Benin, aged 18 years and above, chronic haemodialysis in this unit for over 3 months, and willfully gave their consent. Quality of life was evaluated using questionnaire on Kidney Disease Quality of Life Short-Form French version 1.2 (KDQoL-SF 36). Epidemiological data, nephropathy etiologies and purification parametres were recorded in patients files. Data statistical analysis was performed using SPSS software 11.5. Results: In total 131 patients were involved in the study. The average age was 50.27 ± 12.17 years with a sex ratio of 1.69. Nephroangiosclerosis was the 1st cause. Most patients 128 (97.71 %) received two haemodialysis sessions on weekly basis. The Average Overall Score (AOS) based respectively on SF 36 and KDQoL was 48.55 and 58.55. The average of both SF 36 and KDQoL AOS was 53.55. Factors affecting hemodialytic patients quality of life were vitality, limitations related to mental health and physical condition, burden of kidney disease, effect of the disease on daily life and occupational status. The study revealed that: Patients education level was correlated with vitality (p < 0.017); The number of haemodialyses sessions was correlated with the consequences of kidney disease on daily life (p < 0.025). Conclusion: It is necessary to streng-then the staff by providing a psychologist and a dietician and also build new haemodialysis centres.

Abstract: this paper is on the topic of "evaluation and clinical evidence" and its relevance to the italian context of mental health services. the subject is discussed based on the method of "clinical case construction," which is being developed at the school of specialization in psychiatry of the university of milan. the practice of presenting and discussing cases is a way of evaluating the quality of these services. it is also proof that an evaluation tool can be developed which includes the singularity of the symptom as the axis of clinical work.
Extreme cities and bad places
Paola Viganò
International Journal of Disaster Risk Science , 2012, DOI: 10.1007/s13753-012-0002-6
Abstract: This article considers places where climate change-induced hazards will be particularly important, focusing on two examples, the lagoon location of Venice and the Garonne riverbank location of Bordeaux. The Venice lagoon territory is close to the coast and has a dispersed form of urban development. Our project experiments resulted in the formulation of a series of adaptation strategies to increased disaster risks, including returning current agricultural land and residential areas to their original state as wetlands and marshes before their reclamation during the early decades of the twentieth century. The scenarios introduce space as a relevant variable into the debate about the impact of climate change and adaptation. This article also deals with the recovery of “bad places,” such as the urban blight on the Garonne riverbanks of Bordeaux, and their relationship with sustainability and disaster risks. Increasingly, the emphasis on minimizing energy consumption and promoting recycling forces cities to reuse places of elevated risk. Only very recently in modern urban planning are polluted and risky areas frequently selected for new development projects to reclaim the vast areas of existing brownfields in the name of sustainability. Integrating disaster risk reduction into a new economic and social context has thus become an extremely important part of contemporary urban design and planning for these reclaimed (bad) areas. The research concludes that urban and territorial design should and can integrate the inevitability of risk. This is necessary for developing approaches and strategies that offer some rethinking about “wicked” problems, long-term time horizons, radical imagination, dynamic representations, and minute territorial readings in contemporary urban planning.
La lucha contra el terrorismo de matriz islámica a través del Derecho penal: la experiencia italiana.
Francesco Viganò
Política criminal , 2007,
Abstract: El artículo da cuenta de la línea seguida por el sistema penal italiano en materia de oposición al terrorismo de matriz islámica. Tras exponer la dicotomía entre la “vía norteamericana” y la “víaeuropea” de enfrentamiento del mencionado fenómeno, el autor toma posición en el debate sobre el denominado derecho penal del enemigo, concluyendo que la oposición al terrorismo debe continuar pasando a través del derecho y la jurisdicción penal, y que es tarea de la ciencia penal orientar a la los poderes creadores del derecho criminal en la búsqueda de un punto de equilibrio sostenible entredefensa social y garantías. En seguida se examinan los tipos penales italianos más relevantes utilizados en la práctica de la oposición al terrorismo islámico. Se dedica una atención especial a la participación en una asociación terrorista, figura que, junto con constituir el eje en la materia, ofrece la mayor problematicidad desde el punto de vista de la compatibilidad con los principios constitucionales.
