Model of Effective Control of Leishmaniasis in North Central Morocco and Updating the Mapping of the Circulating Species.

Leishmaniasis is among the most important emerging vector-borne protozoal disease in terms of disability adjusted life year (DALY'S). The main objectives of this study are, firstly to evaluate the epidemiological situation of Cutaneous Leishmaniasis (CL) from 2000 to 2015 in Moulay Yacoub Province and Fez Prefecture and secondly to analyze the impact of several factors (geographical and socio-economic factors) on the distribution of CL in these provinces. In addition, this study aims to identify the circulating species of Leishmania in order to justify the cause of the case maintenance and to prevent possible epidemics. The spatio-temporal evolution of CL from 2000 to 2015 in the study area revealed the endemic and epidemic character of the disease with a variation in the number of cases according to provinces, and districts. The sharp decrease of cases observed in the study area could be explained by the several control measures that concern the different actors of leishmaniasis. According to the statistical study, the presence of leishmaniasis is mainly related to population movement and environmental conditions. The results of the clinical identification of cutaneous leishmaniasis in the study area showed a diversity of clinical features with the presence of symptoms miming for L. tropica or L. infantum. This result was confirmed by the molecular study PCR-ITS1-RFLP.

En absence du vaccin et vu la complexité et la diversité des cycles des leishmanioses au Maroc, en plus de la présence des facteurs de risque (urbanisation anarchique, changements climatiques, facteurs socio-économiques…), notre étude s'intègre dans le cadre du Programme national de lutte contre les leishmanioses qui est une des priorités dans les programmes de lutte instaurés par l'OMS. Les objectifs de cette étude sont premièrement d'évaluer la situation épidémiologique depuis le déclenchement de l'épidémie de leishmaniose cutanée (LC) en 2000 jusqu'à 2015 dans la province de Moulay Yacoub et la préfecture de Fès et secondairement d'analyser l'impact de plusieurs facteurs sur la distribution de la LC. Aussi, cette étude vise à identifier les espèces de leishmanies circulantes au niveau de cette région. L'évolution spatio-temporelle de la LC de 2000 à 2015 dans la zone d'étude a révélé le caractère endémoépidémique de la maladie. La nette diminution après le pic de 2001 des cas de la LC peut être liée aux différents moyens de lutte réalisés annuellement et qui ont concerné les différents maillons du cycle. Selon les résultats de l'étude statistique (Ordinary Least Squares Regression [OLSR] et Chi2), la présence de la LC est principalement liée aux mouvements de la population et aux conditions environnementales. Les résultats de l'approche d'identification ont montré une diversité des caractéristiques cliniques avec la présence de symptômes qui indiquent une LC à L. tropica ou à L. infantum. Ce résultat a été confirmé par l'étude moléculaire PCR-ITS1-RFLP.

[A rare infectious etiology of COPD exacerbation]. / Une étiologie infectieuse rare d'exacerbation de bronchopneumopathie chronique obstructive.

Chronic obstructive pulmonary disease (COPD) is a common respiratory disorder. Its exacerbation is infectious in more than half of the cases: with viral priority, while parasitic causes remain exceptional. In this work, we report a case of a COPD exacerbation caused by a visceral leishmaniasis (VL) complicated by a macrophage activation syndrome in an adult living in a Moroccan non-endemic region for this of leismaniasis form. In such atypical clinical feature, the diagnosis of VL was based on the myelogram after presence of peripheral cytopenia. Despite the seriousness of these pathologies, the early and specific treatment of VL allows a quickly improvement in the disorders caused by these diseases.

Identification of the causative agent of cutaneous leishmaniasis in Chichaoua province, Morocco.

Cutaneous leishmaniasis (CL) in Morocco is caused by three species, Leishmania major, L. tropica and L. infantum. CL has been known in Chichaoua province since 2000. Using DNA extracted from microscopic slides and parasite cultures, collected in the years 2006 and 2009, we identified for the first time L. tropica as the causative agent of CL in this region. Species identification was achieved by performing the ITS1-PCR-RFLP approach. By using this method it was possible to identify parasites in Giemsa stained slides containing less than five parasites per oil-immersion field even they were conserved for up to four months.

[Kidney transplantation and lower tract obstructive uropathy treated by Botox: a case report]. / Greffe rénale et uropathie obstructive du bas appareil traitée par Botox: à propos d'un cas.

INTRODUCTION: The indications for botulinum toxin have been extended in the field of urology, especially in vesicosphincteric dysfunction with good results. The authors report the use of botulinum toxin in a kidney transplant recipient with urethral hypertonia partly responsible for end-stage chronic kidney disease. CASE REPORT: Mr E.J, 25 years old, was operated for bilateral megaureter with vesicosphincteric dysfunction during childhood. He was managed in our department with serum creatinine of 364 mol/l. Ultrasound showed bilateral ureteropelvic dilatation and residual urine of 300 ml. Urodynamic assessment demonstrated a normally active bladder with normal compliance and urethral hypertonia. An intrasphincter injection of 300 units of Botox was performed in May 2003 with a good result for 11 months. He subsequently received a second intrasphincter injection of 200 units with clinical efficacy maintained for at least six months. This patient underwent living-donor kidney transplantation in May 2005. An intrasphincter injection of 100 units of Botox was performed nine days after transplantation, then every six months. With a follow-up of 16 months, renal function is stable with negligible residual urine. DISCUSSION: The use of botulinum toxin in non neurogenic urethral hypertonia has been reported in only a few original articles. Botulinum toxin injection into the striated sphincter of the urethra decreases urethral resistance, improving obstructive symptoms and can be effective in kidney transplant recipients.

Leishmaniasis due to Leishmania tropica MON-102 in a new Moroccan focus.

In Morocco, between March and April 2002, large numbers of human leihsmaniasis cases were detected during a survey at Zouagha My Yacoub province in Fès State. Among 95 cases, 76 were positive by direct observation of Giemsa-stained smears. Sixteen stocks were isolated in NNN medium and identified as Leishmania tropica MON-102, using isoenzyme techniques on starch gel electrophoresis.

[Epidemiologic data in renal lithiasis in adults]. / Données épidémiologiques de la lithiase rénale chez l'adulte.

The morpho-costitutional analysis of 574 urinary lithiasis emitted by tunisean adults permitted to define an épidemiology's profile. This resemble to the épidemiology's profile of under-developed conry: Amore raised frequency of the renal lithiasis at the man than at the woman with a sec ratio of 2.4. An average age of +14 years with a peak to 4th decade in 2 sexes. The upper localitation of the calculi is founded in 94% cases. The fréquency of the relapses, the mode of expulsion and the size of calculi are différent of those published in the litérature. Probably because the time of study which last 4 years is too short, so it don't enable us to find a result like the literature. The surgery is the mode of most fréquent élimination (51%). This s dû to the présence great size calculi in our popûlation and to the récent introduction of the lithotritie in our country.

[Lipid evolution during normal pregnancy]. / Evolution des lipides au cours de la grossesse normale.

We analyzed the relationship between the evolution of pregnancy and the amplitude of the lipid disorders in order to evaluate their chronologic transformations. This research concerned 83 pregnancies aged between 19-40 years during the 3 periods of gestation and 31 healthy control women in the same range of age. Our results showed an increased triglyceride in the 2nd period and an earlier decrease of both, cholesterol, phospholipid and apolipoproteins. These parameters showed a progressive increase of their blood concentrations during the 2nd and the 3rd period of pregnancy, in an other hand we evidenced a good correlation between gestational aged and these variations i.e.: triglyceride and mother's weight; this phenomenon could suggest an eventual role of the nutrition and the hygienic habitude in the lipid metabolism. The correlation between our observed lipid disorders and the mother's age or the parity were not significant.

[Evaluation of a fast test for direct research on streptococcal group A from pharyngeal samples]. / Evaluation d'un test rapide pour la recherche directe du streptocoque du groupe A dans les prélèvements pharyngés.

Importance of streptococcal pharyngitis rapid diagnosis is increasing. 645 patients with pharyngoamygdalitis were tested. The correlation between bacteriologic culture and rapid test is 86%, the sensibility of the test is 68%, its specificity is 92%, while the predictive positive and negative values are 75% and 90%. These results show the interest of the rapid test for the diagnosis of streptococcal pharyngitis.
