Forest and landscape restoration (FLR) practices have been reported to improve soil organic carbon stocks (SOCs) and contributing to climate change mitigation. This study aims to evaluate the impact of combined FLR practices, mainly developed in semiarid regions, on SOCs. The SOCs, soil texture, bulk density (ρ), pH, CO2 emissions, and herbaceous biomass were determined at a 0 - 30 cm depth. The experimental design comprised degraded land without FLR practices and three sets of combined FLR practices. These practices included “zaï” + stone bunds + organic manure + assisted natural regeneration (ANR) used to convert degraded land into forest (GF) and cropland (PARL);“zaï” + stone bunds + crop rotation + crop/fallow successions + ANR used to convert degraded land into cropland (OARL) and “zaï”+ stone bunds + organic manure used to convert degraded land into cropland (KARL). SOCs were highest (20.02 t C ha−1) under OARL compared with the other combinations of FLR practices. SOCs increased by 99% (+0.2 t C ha−1⋅yr−1), 58% (+0.3 t C ha−1⋅yr−1) and 13% (+0.2 t C ha−1⋅yr−1) under GF, OARL and KARL, respectively, and decreased by 15% (−0.1 t C ha−1⋅yr−1) under PARL. This study provides additional information explaining SOC variation in restored degraded land through the implementation of a combination of FLR practices. This is useful for recommending the combination “zaï” + stone bunds + crop rotation + crop/fallow successions + ANR to improve SOCs in the semiarid agroecosystem.

Background: Niger is one of the countries that have the highest fertility rate in the world, with 7, 6 children per woman. Zinder is the most populated region of Niger with 5 million inhabitants that is 1/5 of Niger population. The demographic impact that has affected Niger the last 10 years: unemployment poverty and drug use, spawned violence of all kinds in Zinder region (physical and sexual violence). Sexual abuse is a major risk for poor psychiatric and physical outcomes. As sexual violence has serious consequences on the life and future of women and the community and it concerns our field of intervention, we initiated this study whose objective was to determine the socio-epidemiological and lesional aspects, the consequences and appropriate solutions of sexual violence in the Zinder. Methodology: This was a retrospective collection study of all cases of alleged sexual violence received over a 12-year period from 1 January 2009 to 30 June 2021 in Zinder’s referral maternity wards. Results: During the study period, 441 cases of sexual violence were collected;an annual average of 36 cases (441/12). The frequency is 1.29% on the 34,186 consultations. The mean age was 12.31 years with age extremes of 3 to 43 years. Students accounted for 25.39%. Street vendors were found in 224 cases or 50.79%. The predominant reason for admission is rape in 64.63%. The defloration was 52.15%. Pregnancy was found in 118 cases or 26.75%. HIV serology was positive in 1 victim. School dropout was 26.75%. Conclusion: The victims of sexual violence were minors, mostly street vendors and school children. The lack of means of repression at the time allowed the expansion of this violence. The consequences of sexual violence were severe. Advocacy has improved the phenomen on of sexual violence in Zinder.

Introduction: Adult bone tumors may be primary or secondary. Their diagnosis is often based on the results of imaging tests but can also be completed by biopsy. Case Presentation: We report the observation of a clinical case of fortuitous discovery in the orthopaedic-traumatology department of the national hospital Amirou Boubacar Diallo of Niamey, pathological fracture of the right humeral shaft secondary to metastasis of clear-cell adenocarcinoma of renal origin, a 57-year-old man, a refrigeration engineer by profession, from Niger living in the Middle East. This patient has no known pathological history. He consulted us for pain in his right arm that was more severe at night. All imaging and pathology examinations carried out both in Niger and in the Middle East confirmed the diagnosis of humeral metastasis of clear-cell renal cell carcinoma. Surgical management consisted of tumor resection and Kuntscher-type centromedullary alignment nailing of the fracture site. The loss of bone substance in the fracture is filled with acrylic cement. The treatment was completed by chemotherapy. Conclusion: Bone tumours are most often secondary in location. However, the diagnosis must be sought in the presence of any clinical sign.

Background: In developing countries maternal mortality and morbidity are most often due to the late to consult, poverty and ignorance. Added to this is, the under-medicalization of the health system. The objective of study is to report a case of late consultation and its consequences and make recommendations to improve: case of abdominal pregnancy with hemorrhagic placenta at the Health and Mother Center (CSME) in Zinder/Niger. Clinical Observation: We describe a case of abdominal pregnancy with hemorrhagic placenta in a 24-year-old woman, without profession, resident in the city of Zinder with a low economic level, consulted for abdomino-pelvic pain. She had a notion of amenorrhea for 5 months without any consultation made. She was pale, feverish and had abdominal pain. Ultrasound revealed a 23-week-old fetus and an empty uterus. The diagnosis was abdominal pregnancy. A laparotomy was performed and a The morbidity was hysterectomy and anemia. The postoperative period course was complicated with anemia. The patient was cured on the 9th day with a good vital prognosis. Conclusion: Abdominal pregnancy occurred in a patient who presented a risk factor. Ultrasound was the key diagnostic test. Surgery was the treatment of choice and the prognosis depends on the earliness of the consultation. Community awareness and early consultation with health services can improve the prognosis of abdominal pregnancy.

Objective: Improve the care of patients followed for acute leukemia in the Oncohematology department of the National Hospital of Niamey. Methods: This was a prospective study, over a period of 2 years from January 1, 2018 to December 31, 2019, in patients with acute leukemia in the Oncohematology department of the National Hospital of Niamey (HNN), whose diagnosis was made on a blood smear associated with a myelogram and immunophenotyping and who were consenting. Results: We collected 25 cases of acute leukemia confirmed by myelogram and immunophenotyping. The mean age of the patients was 31.32 years, with a predominance of women, a sex ratio of 0.92. Pupils and students were in the majority with 40% and most came from the Niamey region, i.e. 68%. Anemic syndrome was the most common clinical sign in 96%. ALL predominated in 64% of cases. On the blood count, the hyperleukocytosis was more marked in AML (mean white count: 197256.6 elts/mm3) than in ALL (137891.6 elts/mm3), it was the same for thrombocytopenia which is more marked in AML (75588.89/mm3) than in ALL (52156.25/mm3). Therapeutically, 52% of patients received chemotherapy. The mean overall survival was 16.223 ± 3.191 months, including a mean survival for AML of 6.853 ± 1200 months compared to 21.720 ± 5.920 months for ALL. Conclusion: Acute leukemia still remains a major problem in our context, due to the precariousness of limited financial, diagnostic and therapeutic resources. Thus reflecting in our results, the increasing number of cases, the diagnostic delay and the guarded prognosis. This is the reality in several other countries in the sub-region and even in certain developed countries.

Introduction: Pregnancy, childbirth, and their consequences continue to be the leading cause of death, illness, and disability among women of reproductive age in developing countries. In Niger, maternal deaths account for about 39% of all deaths of women aged 15-49. Our aim was to identify the factors linked to maternal mortality in order to contribute to its reduction. Method: this is a descriptive retrospective study of 379 cases of maternal deaths collected at the Maradi CSME from January 1, 2018, to December 31, ***: Our study’s maternal mortality ratio is 2645.72 per 100,000 live births. The mean age of our patients was 27.46 years, with extremes ranging from 15 to 47 years. The 20-24 age group was the most represented, with 88 cases (23.2%). Housewives were 361 (95.3%), and 334 patients (88.1%) were uneducated. There were 261 of them from rural areas, i.e. 69%. The mean parity in our study was 3.46, with extremes ranging from 0 to 15. Multiparous patients 117 cases (30.9%) represented the most significant proportion. Only 42 patients (11.08%) had performed four or more antenatal consultations. Direct obstetric causes accounted for 56.73% of the causes of maternal death. Anemia was the leading cause of maternal death (31.66%). Nearly half of the patients had died before 24 hours after admission, i.e. 49.86%. Conclusion: Maternal mortality remains a significant challenge for developing countries, given its magnitude and timid decline. The fight to reduce maternal mortality must be the priority of our countries’ health policies.

Malignant non-Hodgkins lymphoma (MHNL) of the uterus is uncommon. We report a case diagnosed on the basis of histologic and immunohistochemical studies of a hysterectomy specimen induced by a very painful pelvic mass in a 50-year-old patient with no previous history of the disease. It was classified as Ann Arbor IV Bb after imaging, given the medullary infiltration and signs of clinical and biological evolutivity: the patient had received two courses of chemotherapy, CHOP protocol. She died 23 days after the second treatment due to a hypertensive crisis.

Introduction: Emergency obstetric hysterectomy (EOH) is a lifesaving procedure that is performed as a last resort in cases of severe postpartum haemorrhage. Objective: The objective of this study was to determine the incidence, socio-demographic profile of patients, indications, management and maternal-fetal outcomes of EOH in a maternity hospital with limited resources in Niger. Methodology: This was an eight-year retrospective cohort study involving the analysis of medical records from patients who underwent emergency obstetric hysterectomies between 1 January 2015 and 31 December 2022 at the Mother and Child Health Centre (MCHC) in Maradi, Niger. The epidemiological data, indications, and outcomes of EOH were collated and subjected to analysis using the statistical software package SPSS 21.0. Comparisons were made using the Chi-squared test. A p-value of less than 0.05 was considered statistically significant. Results: During the study period, 239 cases of emergency obstetric hysterectomy were recorded out of 269,710 deliveries, representing a frequency of 0.89%. The mean age of the patients was 32.41 years (range: 17 - 50 years). The patients were identified as married (239 cases, 100%), unemployed (228 cases, 95.4%), and not attending school (215 cases, 90%). The largest number of cases were observed in large multiparous women (i.e., those with more than five children), representing 58.6% of the total number of cases (140 patients). The average parity among this group was 6.15 children. The majority of patients (229 patients, 95.82%) had undergone in utero transfer, with 169 patients (70.71%), originating from peripheral maternity units in the Maradi region. Upon admission, 116 patients (48.53%) exhibited active genital haemorrhage, while 58 patients (24.26%) were in shock. The primary indications for hysterectomy were uterine rupture (153 patients, 64%), uterine atony (77 patients, 32.2%), and placental accreta (six patients, 2.5%). Hysterectomy was performed
