UrĂštrocĂšle post-traumatique chez lâhomme: A propos de 2 cas
RĂ©sumĂ©Affection rare chez lâhomme, le diverticule urĂ©tral est souvent dâorigine acquise. Nous rapportons deux cas dâurĂštrocĂšle post-traumatique chez des sujets jeunes qui ont Ă©tĂ© traitĂ©s avec succĂšs par chirurgie ouverte et nous en discutons les aspects cliniques para cliniques et thĂ©rapeutiques.AbstractUrethral diverticulum is unusual in male where it is often acquired. We report two cases of post-traumatic urethrocele in young male managed successfully by open surgery. We describe herein, the clinical, paraclinical and therapeutic features
Cancer du testicule: particularités cliniques et limites thérapeutiques en milieu hospitalier urologique au Sénégal
RĂ©sumĂ©ButEtudier les particularitĂ©s cliniques et les limites thĂ©rapeutiques de la prise en charge du cancer du testicule au SĂ©nĂ©gal.Patients et mĂ©thodesCette Ă©tude, rĂ©trospective, Ă©tait menĂ©e sur une pĂ©riode de 15 ans de Janvier 1997 Ă Janvier 2012. Vingt-deux dossiers Ă©taient colligĂ©s mais 17 Ă©taient exploitables.RĂ©sultatslâincidence annuelle moyenne Ă©tait de 1,13 cas par an. LâĂąge moyen des patients Ă©tait de 27 ans ± 9,5. La tranche dâĂąge la plus concernĂ©e Ă©tait celle de 21 Ă 40 ans. Les circonstances de dĂ©couverte Ă©taient dominĂ©es par la grosse bourse (10 cas) et en cas de vacuitĂ© scrotale, la masse abdominale ou pelvienne (7 cas). Lâorchidectomie a Ă©tĂ© le principal geste thĂ©rapeutique. Elle a Ă©tĂ© rĂ©alisĂ©e par voie inguinale haute (8 patients) et par voie trans-pĂ©ritonĂ©ale (7 patients). Sur le plan histologique, nous avions notĂ© une prĂ©dominance des tumeurs germinales non sĂ©minomateuses avec 10 cas de carcinome embryonnaire dont un cas de type infantile. En post opĂ©ratoire, 7 cas de progression avaient Ă©tĂ© notĂ©s dans le suivi: 3 cas de carcinose pĂ©ritonĂ©ale, 3 cas dâenvahissement locorĂ©gionale avec des adĂ©nopathies rĂ©tropĂ©ritonĂ©ale et 1 cas de mĂ©tastase pulmonaire. Avec un recul moyen de 6 mois, 9 patients Ă©taient dĂ©cĂ©dĂ©s, 4 Ă©taient perdus de vue et les 4 autres Ă©taient vivants.ConclusionLe cancer du testicule reste rare au SĂ©nĂ©gal et concerne des sujets jeunes. Le diagnostic est encore posĂ© Ă des stades trĂšs Ă©voluĂ©s avec une lourde mortalitĂ©.AbstractObjectiveTo investigate the clinical features and limitations of therapeutic management of testicular cancer in Senegal.Patients and methodsThis is a retrospective study over 15 years period between January 1997 and January 2012. Twenty-two cases were collected but only 17 had complete data for analysis.ResultsThe average annual incidence was 1.13 cases per year, with a mean age of 27±9.5 years. The most affected age group was between 21 and 40 years.Clinical diagnosis was suspected by the presence of a scrotal swelling in10 cases and by empty scrotum associated with abdominal or pelvic mass in the remaining 7 cases. Orchiectomy was the main treatment option, done either by high inguinal approach in 8 patients or by trans- peritoneal route in other 7 patients. Histologically, a predominance of embryonic non seminomatous germ cell carcinoma was noted in 10 cases including infantile type in one case. Seven cases developed disease progression:3 cases of peritoneal carcinmatosis, 3 other cases of locoregional invasion with retroperitoneal lymphadenopathy and one case of pulmonary metastasis. At a mean follow up of six months, nine patients died, four were lost to follow up while the remaining four cases were still alive.ConclusionTesticular cancer is a rare tumor in Senegal and usually involves young people. Clinical diagnosis is always done at very advanced stage with a very high mortality rate

Effects of furrow diking and tillage on water storage, plant water use efficiency and yield of sorghum
In water deficit areas, like the Texas Northern High Plains, cultural
practices are needed to reduce runoff and capture rain water. Studies
were conducted at Bushland, Texas, on Pullman clay loam (fine, mixed,
thermic Torrertic Paleustoll) to improve water storage, sorghum
(Sorghum bicolor (L.) Moench) water use efficiency, and grain yield.
Treatments were conventional tillage plus furrow diking (FD),
conventional tillage (CT), no-tillage with wheat Triticum aestivum
residue maintained on the plots (NT+) and no-tillage with wheat residue
removed (NT-). The FD and NT+ treatments were more effective than CT
and NT treatments for improving precipitation storage by reducing and
even preventing runoff and increasing infiltration. The more efficient
use of soil water with the FD and NT+ treatments were reflected in
greater sorghum grain yield. Average grain yield with the FD treatment
was 4840 kg ha-1, which was about 800 kg ha-1 more than with the CT and
NT-treatments. Grain yield with the NT+ treatment was 15 % greater than
with the CT and 17% greater than with the NT-treatment.Dans les zones deficitaires en eau do sol comme les Hautes Plaines du

des traitements CT et NT-. Le rendement grain du traitement NT+ etait
15 % superieur a celui du CT et 17% superieur acelui du traitement NT-
Impact of climate variability modes on trend and interannual variability of sea level near the West African coast
The main objectives of this study are to assess the regional distribution of sea level in terms of trend and interannual varibility and to analyze the impacts of climate variability modes such as El Niño-Southern Oscillation (ENSO) events, Tropical Atlantic Climate Modes of Variability (TACMV), North Atlantic Oscillation (NAO) on interannual variability and trend of sea level near the West Africanscoasts. Indices associated with these phenomena are from the National Oceanic and Atmosphere Administration (NOAA), the Global Mean Sea Level (GMSL) time series provided by AVISO (ArchivingValidation and Interpretation Satellite Oceanographic Center) and the Regional Mean Sea Level (RMSL) gridded data by CMEMS (Copernicus Marine Environment Monitoring Service). The results show thatthe mean regional trend of sea level is similar to the global one but the time evolution at interannual and decadal scales does not follow the pattern of global sea level. Our analysis suggests an influence ofENSO events in the Atlantic coast of West Africa. In particular, we observed negative RMSL anomalies during the two strongest El Niño events (1997-1998 and 2015) and a strong positive RMSL anomalyduring the La Niña event of 2011 (the strongest over the last two decades). The analysis also reveals an influence of TACMV and NAO on the interannual sea level variability, essentially through regional SeaSurface Temperature (SST) changes. The study shows that a time series of at least 10 years is required to estimate the trend in sea level rise in West Africa. Sub-decadal trends, primarily reflect naturalclimate modes, rather than variations in climate change. This study also shows that the distribution of sea level rise in the West African region is heterogeneous with higher values near the coast of WestAfrica and near the equator
Estimation and correction of depth range and echo level errors due to water-column temperature and salinity on sound scattering layer [résumé]
ICES. Working Group of Fisheries Acoustics, Science and Technology (WGFAST), Somone, SEN , 25-/04/2022 - 28/04/2022Water temperature and salinity are the key environmental parameters involved in the acoustic signal processing. In absence of clear procedure, temperature and salinity value are usually used at a fixed point in the water column to estimate the sound celerity in the studied area. Consider-ing temperature and salinity as having negligible effects in estimates of acoustic variables may lead to errors in dependent acoustic variables as the volume backscattering coefficient Sv, the nautical area backscattering coefficient sA and the target distance, i.e., depth for vertical echo-sounder. We examine the impact of environmental errors and their effects on the level of Sv, sA and range r. The results shown that the effect may not be negligible. The nautical area backscat-tering coefficient sA was the most affected by environmental errors. The deep ocean areas were the most concerned by these errors vs. surface and shallow coastal areas. Failure to correct for environmental errors in acoustic studies can lead to inaccurate results on the positions of the targets studied and biomass assessment. Abacuses were built to identify areas of interest where environmental corrections should be implemented and we share corrective code integrating tem-perature and salinity water profile for fisheries acoustics data correction
