A hunting arrow traumatism to the head: A case report from Niger.

Key Clinical Message: Arrow injuries have not disappeared in our environment despite the advances in the development of warfare tools in the world. All regions of the body can be the target of these arrows and in particular the cephalic region whose gravity will depend on the structures reached. Abstract: With the development of modern weapons of war, arrow wounds have become rare in developed countries, but they are still common in developing countries, including Niger. These injuries are often serious and life-threatening when they are in the head and neck region, due to the presence of major vessels and vital organs in these areas of the body. Extraction of these arrows is usually difficult due to the proximity of major vital structures. Unskilled extraction can aggravate the injury or result in unintentional damage to vital structures with imminent risk of death. We present the case of a patient with a homemade arrow to the head in the left periorbital region that we successfully extracted at the National Hospital in Niamey. Our objective is to highlight the experience with this patient and review some reports in the literature.

Kernohan-Woltman notch phenomenon in patient with subdural hematoma and ipsilateral hemiparesis in Bukavu.

Key Clinical Message: Kernohan-Woltman phenomenon is a rare and paradoxical neurological situation in which a transtentorial lesion leads to compression of the contralateral cerebral peduncle responsible for compression of the descending corticospinal fibers with clinical consequence of a motor deficit ipsilateral to the primary lesion. This phenomenon should attract the attention of clinicians in order to avoid unfortunate incidents such as wrong-side craniotomy in neurosurgical practice. In this work, we report a similar situation. Abstract: The Kernohan-Woltman notch phenomenon is a rare and paradoxical neurological situation in which transtentorial damage is observed leading to compression of the contralateral cerebral peduncle responsible for compression of descending corticospinal fibers with the clinical consequence of a motor deficit ipsilateral to the primary lesion. This phenomenon has been found in several situations including tumors and cerebral hematomas after craniocerebral trauma. In this work, we have reported the case of a 52-year-old man with hemiparesis ipsilateral to a large chronic subdural hematoma.

Atypical caudal regression syndrome with lumbar agenesis, hypoplastic sacrum without sacroiliac joints in the eastern Democratic Republic of Congo: a case report.

The agenesis of any segment of the lower spinal column referred to as "caudal regression syndrome" (CRS) is a rare congenital defect of the spine. This malformation is characterized by the absence of some or the entire lumbosacral vertebral segment. Etiological factors remain unknown. We report an atypical caudal regression syndrome with lumbar agenesis, disconnected from the remaining hypoplastic sacrum, in the Eastern part of the Democratic Republic of Congo (DRC).An 11-month-old female infant with no particular fetal or maternal history presented limb weakness with flexed knees and flanges in the popliteal fossae, sphincter atony, and a sensation of emptiness on palpation in the lumbosacral region. A 3D CT scan of the spine showed the absence of the lumbar spine and disconnection of the upper segment of the thoracic spine from the hypoplastic sacrum. We noted also the absence of the sacroiliac joints bilaterally and an unusual trigonal shape of the iliac bones. MRI and sonographic examination are required in the investigation of the disease. The management is multidisciplinary and depends upon the degree of the defect. Spine reconstruction has proven to be a valuable management technique but has many complications. We wanted to draw the medical world's attention to the existence of this extremely rare malformation in the east of the Democratic Republic of Congo, a mining area.

Surgical Aneurysm Repair of Aneurysmal Subarachnoid Hemorrhage in Sub-Saharan Africa: The State of Training and Management.

BACKGROUND: In a resource-limited setting such as sub-Saharan African countries, neurosurgeons need training and fellowship for surgical repair of aneurysmal subarachnoid hemorrhage (aSAH). Surgical repair of ruptured aneurysms costs less and requires less instrumentation compared with endovascular procedures. The purpose of this study is to evaluate the state of training and management of aSAH in sub-Saharan Africa training centers. METHODS: An e-survey was sent as a Google Form to neurosurgeons and neurosurgical trainees in neurosurgery training centers in sub-Saharan Africa; responses were accepted from September 9 to October 23, 2022. Statistical analysis was performed using Microsoft Excel and JAMOVI 3.2. RESULTS: All 44 centers from 17 countries responded. Most of the respondents were neurosurgery residents (n = 30; 68.18%). The level of training on clipping was basic after completing the residency program (n = 18; 40.91%). Twenty respondents (45.45%) identified that fellowships on aneurysmal clipping and endovascular treatment are offered abroad. Thirteen participants (29.55%) indicated that endovascular treatment is available at their institutions. The most common challenges with lack of training for neurosurgical aneurysm clipping were scarce scholarship and collaboration with training centers from high-income countries (n = 33; 75%). The availability of intensive care unit beds also contributed to the presence of neurosurgical training of aneurysm clipping (12.1 ± 3.67 vs. 9.29 ± 5.82; P = 0.05). CONCLUSIONS: In sub-Saharan African countries, the lack of collaborations with high-income countries for training through fellowships of young neurosurgeons for aneurysm repair seems to be the most important challenge that should be overcome.

Hand grenade blast injuries in the Eastern Democratic Republic of Congo: a case series of 38 patients.

INTRODUCTION: The armed conflict in the Kivu province of the Democratic Republic of Congo has caused close to 12,000 deaths. One of the most lethal weapons in armed conflicts is the high explosive hand grenade. The study aimed to describe the epidemiology, presentation, and outcomes of hand grenade blast injuries (HGBI) in the Kivu province. METHODS: In this case series, the authors present 2017 to 2020 HGBI admissions at a Congolese trauma center. Measures of central tendency and spread were computed for continuous data. Complication and mortality rates were equally computed. Admission-to-discharge data were disaggregated by the body part injured and by complication status and visualized using time-to-event curves. RESULTS: Thirty-eight HGBI patients aged 31.4 (range 17-56) years were included in the study. Twenty-six (68.4%) were male and the patients were admitted 1.8 days post-injury on average. The patients were hemodynamically stable at admission; 84.2% received the antitetanic vaccine, 21.1% received broad-spectrum antibiotics, and all were debrided (100.0%). The complication rate was 13.2%, and the most common complication was anemia (7.9%). In addition, the mortality rate was 2.6%. The median admission-to-discharge time was 17.0 (range 4-71) days, and it was prolonged in patients with lower extremity injuries (23.0 days). CONCLUSION: HGBIs cause avertable death and disability in the Kivu regions. These data suggest that the burden of HGBIs can be reduced with appropriate preventive and health systems strengthening interventions.

Firearm injuries among children due to the Kivu conflict from 2017 to 2020: A hospital-based retrospective descriptive cohort study.

INTRODUCTION: Firearm-related injuries are deadly but avoidable. The case of Kivu, a region in the Eastern Democratic Republic of Congo (DRC), is alarming. Decades of unresolved regional conflicts birthed armed groups that have massacred inhabitants and injured several children. This regional instability has also created barriers to seeking and obtaining timely care, decreasing the survival rate. This region's lack of data on paediatric fatal and nonfatal firearm injuries (F&NFFIs) needs studying. Thus, we aim to determine the prevalence and evaluate the outcomes of paediatric F&NFFIs in Kivu. METHODS: We included all F&NFFI paediatric patients (≤18 years), admitted at our institution between 2017 and 2020. We extracted data from patient records. Next, we assessed the relationship between determinants of paediatric outcomes using the Chi-square test and the student's t-test. Confounders were identified using cox regression. RESULTS: This study included 101 paediatric patients, mostly male (63.4%), with an average age of 15.9 years residing 164.4 km on average from the hospital. On average, they were admitted 2.9 days post-injury, with the most affected anatomical regions being lower limbs (53.5%) and upper limbs (18.8%). The mean length of stay was 52.9 days, and the mortality rate was 4.0%. Also, injury complications increased the mean length of stay and mortality rate. In addition, mortality was correlated with circulatory failure and anaemia. DISCUSSION: Paediatric F&NFFIs in Eastern DRC is a preventable tragedy. Mortality is increased by injury complications and correlates with some biological factors. Prevention strategies should be developed to protect children and appropriate measures should be established to improve rates of prehospital care and early hospital presentation to lower mortality and improve paediatric outcomes.

Fatal and nonfatal firearm injuries in the eastern Democratic Republic of Congo: a hospital-based retrospective descriptive cohort study assessing correlates of adult mortality.

INTRODUCTION: The Eastern Democratic Republic of Congo (DRC) has been the battleground for multiple armed conflicts, resulting in many fatal and nonfatal firearm injuries (F&NFFIs). Chronic insecurity has stressed the health system's resources and created barriers to seeking, reaching, and receiving timely care further increasing the F&NFFI burden. Our institution is the largest trauma center in the region and receives the bulk of F&NFFI cases. We aimed to identify correlates of mortality in Congolese F&NFFI patients. METHODS: We included all F&NFFI patients admitted to our institution between 2017 and 2020. We extracted data from patient charts and admission logs. We identified mortality correlates using the two-sample t-test, Chi-square test, and multivariable regression analysis. A P-value of less than 0.05 was considered statistically significant. RESULTS: This study included 814 adult patients, mostly male (86%) with an average age of 34.5 years and living 154.4 km away from the hospital on average. The most affected anatomical sites were the lower limbs (48.2%) and upper limbs (23.2%). The median length of stay was 34.0 days, and the in-hospital mortality rate was 3.6%. In addition, mortality was negatively correlated with diastolic blood pressure (P = 0.01), SaO2 (P < 0.001), and hemoglobin concentration (P = 0.002). CONCLUSION: F&NFFIs cause an enormous burden in the region, and mortality is correlated with some clinical and biological variables. Thus, the study findings will inform F&NFFI referral, triage, and management in low-resource and mass casualty settings.
