Introduction: Children involved in road accidents most often suffer head or limb injuries. The severity of these injuries varies according to the age of the child, the type of road user and whether or not protective devices are used. The aim of this study was to carry out a census of admissions and to identify the epidemiological and clinical profile of children involved in road traffic accidents at Donka National Hospital. Methods: This is a descriptive cross-sectional study of children involved in traffic accidents over a 3-month period from September 1 to November 30, 2021. All children admitted to the emergency department for a traffic accident were included in the study. Results: During the study period, 435/530 children (82.1%) were victims of road accidents. Boys accounted for 54.94% of cases, compared with 45.06% for girls. The age group most affected was 12-17 years old (48.97%). October had the highest accident rate (36.4%). Pedestrians are most affected (52.87%). Bicycles and mopeds were involved in 59.77% of accidents. Head injury was the most frequent pathology (33.33%). The study showed that 12.64% of victims were referred to intensive care, pediatric surgery, etc. We recorded 8 cases of death (1.84%). Conclusion: This study highlighted the characteristics, incidence and risk factors for accidents in children admitted to emergency departments. Accident prevention, particularly serious accidents in children, requires more precise knowledge of the factors and circumstances leading to their occurrence.

Introduction: Growth is a reflection of a child’s health and nutritional status. Children with sickle cell disease often have slower statural and weight development. The aim of this study was to evaluate the nutritional profile of children with sickle cell disease (SCD) registered in the CEMECO centre database. Methodology: This was a cross-sectional study with simple random sampling of children aged 1 to 16 years registered in the clinic database. Results: We collected information on 208 children, 121 of whom had sickle cell disease and 87 of whom were normal, with a sex ratio of 1.02. The mean age of the sickle cell patients was 8.7 ± 4.4 years, while that of the non-sickle cell patients was 9.5 ± 4 years. Haemoglobin electrophoresis revealed 103 homozygous (SS), 18 double heterozygous (SC, SBetaThal, SE) and 87 normal (AA) and/or sickle cell trait (AS) sickle cell cases. We observed a significant difference in the height/age ratio (P ¥). Conclusion: The results of our study revealed stunted growth in children with sickle cell disease.

Blood transfusion saves lives and reduces morbidity and mortality for a large number of diseases and clinical conditions, but it is not without danger. The aim of this study was to determine the seroprevalence of HIV and hepatitis B in blood donors received at the regional Blood Transfusion Centre of N’Zérékoré (Guinea). This was a 5-year retrospective analytical study. We included records of blood donors aged 18 to 60 years admitted to the N’Zérékoré Regional Blood Transfusion Centre for blood donation from January 2016 to December 2020. We performed a descriptive analysis followed by Chi-2 or Fish-er-exact tests and the Student or Wilcoxon test, followed by multivariate logistic regression. In this study, donor age ranged from 18 - 60 years, with a pre-dominance of donors aged 25 - 34 (44.2%). Male donors were the most represented in our study (79.0% versus 21.0% female). More than half of the donors were blood group O (55.6%). We observed a seroprevalence of 3.6% for HIV, 13.4% for HBsAg and 0.2% for co-infection. In our series, age 25 - 34 (OR = 1.89 and P = 0.001) and 35 - 44 for HIV (OR = 2.01 and P = 0.001), HBsAgserostatus (OR = 3.04 and P = 0.001) and blood donation history (OR of 3.04 and P = 0.001) were factors associated with HIV positivity (P < 0.05). In our study, HIV serostatus (OR = 3.04 and P = 0.001) and blood donation history (OR = 0.01 and P = 0.001) were factors associated with HBsAgseropositivity. We reported a high prevalence of HIV and HBsAg. Sex, serological status and blood donation history were associated factors.

Introduction: The underweight at birth is recognized as a major cause of morbidity and mortality in childhood. Objective: To identify maternal and obstetric sociodemographic factors associated with low birth weight. Patients and Methods: This is a retrospective study of analytical type that examined the records of women who gave birth in the Obstetrics and Gynecology department of Ignace Deen National University Teaching Hospital from 1st December 2016 to 30th April 2017. The analysis was made with the R version 3.3.1 software. We did a univariate and multivariate analysis. Outcomes: Out of the 1633 live births of single pregnancies that occurred during the study period, 109 children were born with a low weight (<2500 g) corresponding to a rate of 6.7%. In univariate analysis, we found a significant association between low birth weight and maternal single status (p = 0.019), maternal weight less than 60 kg (p = 0.038), primary parity (p = 0.018), maternal history of abortion (p = 0.001), history of preterm birth (p < 0.001), arterial hypertension (p < 0.001), anemia (p < 0.001) and malaria (p < 0.001). In multivariate analysis, the variables associated with low birth weight were: history of preterm delivery with OR of 8.5 [1.8 - 40.1], history of abortion (OR = 4.4 [1.4 - 13.9]), malaria (OR = 23.8 [6.1 - 92.5]), anemia (OR = 11.8 [3.7 - 38.2]) and high blood pressure (OR = 5.4 [1.6 - 17.9]). Conclusion: The decrease in frequency of low birth weight in Guinea will be done by improving the quality of prenatal care with an emphasis on screening, prevention and treatment of malaria, anemia and high blood pressure during pregnancy, prevention of abortion and premature birth.

Introduction: A congenital malformation is defined as a morphological abnormality of an organ or body region resulting from an abnormal developmental process during the formation of the embryo or fetus. Depending on their type, location and size, malformations can cause functional, psychological and aesthetic defects. The aim of this study is to document the frequency of congenital malformations, describe the characteristics of malformed newborns and their biological mothers, and identify the different types of malformations presented by newborns at the INSE. Methods: Descriptive cross-sectional study of clinically visible malformed newborns. It was carried out from January 1, 2021 to January 1, 2022 at the INSE neonatology unit. Epi info version 3.1 software was used for data entry and analysis. Results: Of a total of 2332 neonates hospitalized during the study period, 81 (3.5%) cases had at least one clinically visible congenital malformation. Nearly 84% had an age ≤ 7 days at the time of admission. The male sex was most concerned (60.5%). Newborns referred by a health facility accounted for 84%. Malformations of the digestive system accounted for 30.9% of cases, followed by those of the limbs (19.8%) and poly malformative syndrome (19.8%). Conclusion: This study shows that congenital malformations exist and are frequent in Guinea. Our results could therefore be the starting point for the future establishment of a national register of congenital malformations.

The objective of the study was to report the results of the surgery of the Vesico-vaginal fistula (VVF) transection types at CHU Conakry. Methods: This was a prospective descriptive study that focused on 64 patients operated for VVF transection type at the Urology department of CHU Conakry between January 2013 and December 2015. Four types of transection were defined according to the state of the urethra and vagina, the size of the fistula, the peri-fistulous tissue and associated lesions. The variables studied were the proportion of transection, age, the type of transection, the number of previous cures, the operative technique, the complications and the results after a follow-up of 3 months. Results: Transection accounted for 47.05% of the obstetric fistulas. The average age was 25.18 years old (14-43 years old). This was a Type I transection (11 cases), type II (27 cases), type III (19 cases) and type IV (7 cases). The surgical approach was vaginal in 64 cases. Fistulorraphy with a confection of a new cervix and cervico-urethral anastomosis was conducted in 19 patients, combined with bladder flap urethroplasty (30 patients) or vaginal flap (15 others). We recorded healing in 37 cases. Conclusion: Transection type VVF is a severe VVF. The preferential surgical approach was vaginal. Technical difficulties were related to associate lesions and the continence system affected.

Introduction: Middle ear surgery is increasingly performed in our department. Our goal was to take stock of this activity in the ENT department of the Donka National Hospital. Equipment and Methods: It was a descriptive and retrospective study;it involved 71 patients’ records operated from January 1, 2018 to December 31, 2023. We included the files of patients who had a middle ear surgery including the post-operative report and follow-up. Incomplete or illegible records were excluded. The parameters studied were epidemiological, otoscopic, tomodensitometric, surgical indications, surgical techniques and results. Results: We recorded 71 middle ear surgeries out of 548 ENT surgeries, the prevalence was 12.96%. The average age was 23 years (type-deviation = 17, 29 years) with extremes of 3 to 75 years. According to the preoperative audiometry, the deafness was medium (48.8%), mild (36.9%) and severe (14.3%). The operative indications were among others: perforation of the tympanic sequellar (52.5%), chronic otomastoiditis (23.8%), cholesteatoma (15%) and seromuqueous otitis (8.7%). We performed 70 tympanoplasties (90.9%), 50 mastoidectomies (64.9%) and 7 trans-tympanic aerators (9.1%). One month after surgery, the neotympanum was constituted in 86%, and the hearing gain was between 11 and 15 dB in 18.3% of cases. Conclusion: Middle ear surgery was infrequent. Young subjects are the most concerned. Tympanoplasty and mastoidectomy are the main surgical techniques. The anatomical and functional results are appreciable.

Introduction: Ventricular septal defect (VSD) is the most common congenital heart disease of all congenital heart defects. The aim of this study was to investigate the echographic, therapeutic and evolutionary aspects of ventricular septal defects (VSD) in the general cardiology department of the Hôpital National Ignace Deen. Methods: A retrospective data collection was carried out from January 2018 to December 2023 including 85 cases of isolated IVC was performed. The variables studied were epidemiological, clinical, paraclinical, therapeutic and evolutionary. Results: Of the 320 patients seen during the study period for congenital heart disease, 85 (26.556%) were isolated IVCs. Age at diagnosis ranged from 3 months to 16 years, with an average age of 3.59 years. The most represented ethnic group was the Fulani (50.58%). The 8.24% came from consanguineous marriage versus 22.35%. 91.76% of children had a history of bronchitis. The most common clinical signs found were systolic murmur (90.58%), growth retardation (51.76%). Only 4 cases (4.70%) had a malformation associated with IVC represented by DiGeorges disease (2.35%) and trisomy 21 (2.35%). Nearly half the patients had type IIb VIC (44.71%). The other half were represented by type 1 (18.82%), type IIa (20%), type III (10.59%) and type IV (5.88%). According to site more than two-thirds of VICs (71.64%) were perimembranous in location, followed by infundibular (16.47%) and muscular (11.76%) VICs. In our study 55.29% presented an indication for both surgical intervention and medical treatment, while 16.47% required only medical treatment. In contrast, 28.23% were placed under exclusive surveillance. Of the 47 patients for whom surgery was indicated, 29 (61.17%) underwent surgical repair, while 18 (38.83%) were awaiting confirmation for surgery. Conclusion: VIC is the most common congenital heart disease. An early detection strategy and the establishment of specialized centers could improve the outcome of these chil

Effect of Planting Date on Yield and Yield Components of Grain Sorghum Hybrids

引用

American Journal of Plant Sciences 2024年第5期15卷 387-402页

作者： Bandiougou Diawara sory diallo Brahima Traore Scott Staggenbord Vara Prasad Institut D’ Economie Rurale (IER) Bamako Mali Manhattan KS USA

In Kansas, productivity of grain sorghum [Sorghum bicolor (L.) Moench] is affected by weather conditions at planting and during pollination. Planting date management and selection of hybrid maturity group can help to avoid severe environmental stresses during these sensitive stages. The hypothesis of the study was that late May planting improves grain sorghum yield and yield components compared with late June planting. The objectives of this research were to investigate the influence of planting dates yield and yield components of different grain sorghum hybrids, and to determine the optimal planting date and hybrid combination for maximum biomass and grains production. Three sorghum hybrids (early, medium, and late maturing) were planted in late May and late June without irrigation in Kansas at Manhattan/Ashland Bottom Research Station, and Hutchinson in 2010;and at Manhattan/North Farm and Hutchinson in 2011. Data on dry matter production, yield and yield components were collected. Grain yield and yield components were influenced by planting date depending on environmental conditions. At Manhattan (2010), greater grain yield, number of heads per plant, were obtained with late-June planting compared with late May planting, while at Hutchinson (2010) greater yield was obtained with late May planting for all hybrids. The yield component most affected at Hutchinson was the number of kernels∙panicle−1 and plant density. Late-May planting was favorable for late maturing hybrid (P84G62) in all locations. However, the yield of early maturing hybrid (DKS 28-05) and medium maturing hybrid (DKS 37-07) was less affected by delayed planting. The effects of planting dates on yield and yield components of grain sorghum hybrids were found to be variable among hybrid maturity groups and locations.
