Challenges and strategies in the surgical management of traumatic spinal cord injuries in the Democratic Republic of the Congo.

BACKGROUND: Significant progress has been made in the management of traumatic spinal cord injuries. However, deep disparities persist in developing countries. This work aims to describe the different challenges in the surgical management of traumatic spinal cord injuries at the Kinshasa University Teaching Hospital and some strategies implemented to overcome them. METHODS: This is a cross-sectional study of 105 patients from January 2016 to June 2023. The variables of interest included: gender, age, cause, levels of lesion, hospital admission modalities, time to admission, time to surgery, AIS score at admission and on discharge, treatment, pre, peri- and post-operative complications and outcome. RESULTS: We admitted 105 patients. Only 16 % of them were taken to hospital in an ambulance. The average admission time was 49.9 ± 81.79 days. Seventy-two patients (68.6 %) were operated. The average time to surgery was 62.43 ± 85.20 days. No patient was stabilized at the trauma site. Osteosynthesis was performed with appropriate implants in 63.2 % and with improvised elements in 26.8 %. Four patients were operated without an image intensifier. Short-segmental fixation was performed in 8 patients. Twenty-one patients developed pressure ulcers. At discharge, 24 patients recovered their neurological function. Neurological status remained stationary in 43 patients. Five patients died. Seventeen patients went to rehabilitation center. There was no significant difference between the improvised strategies implemented and conventional procedures on functional recovery upon discharge from hospital or rehabilitation centre (p-value : 0.838 and 0.468 respectively). CONCLUSION: Our establishment faces many challenges in TSCI surgery: lack of pre-hospital emergency services and mutual health insurance, delay in admission, lack of surgical implants and image intensifier, the poverty of the population. Some strategies have been implemented to overcome some of them.

Profil clinique, thérapeutique et devenir des traumatismes vertèbro-médullaires aux Cliniques Universitaires de Kinshasa en République Démocratique du Congo / Clinical, therapeutic and outcome of vertebro medullary traumas at Kinshasa University Hospital, in the Democratic Republic of Congo

Les traumatismes vertébromédullaires (TVM) en Afrique subsaharienne sont très peu documentés. L'objectif de ce travail était de décrire les aspects cliniques, thérapeutiques et évolutifs de TVM. Méthodes. C'était une série analytique des cas de TVM soignés aux Cliniques Universitaires de Kinshasa (CUK) entre 2016 et 2022. Les variables d'intérêt englobaient les données cliniques, thérapeutiques, le score ASIA à l'admission et à la sortie, et le devenir. Nous avons recouru au test de Chi carré de Pearson pour comparer les proportions. Résultats. Sur les 123 patients opérés pour lésions vertébro-médullaires, 62 cas étaient traumatiques (50,4 %). Le sexe masculin était prépondérant (75,8 %). Leur âge moyen était de 36,0 ± 13,0 ans. Les accidents de la voie publique (74,2 %) en étaient la principale cause. A l'admission, il y avait 58,1% des paraplégiques et 21 % des tétraplégiques. Vingt-sept patients (43,5 %) ont été admis 1 à 2 mois après le traumatisme. Les patients classés ASIA A représentait 62,9 % des cas. Vingt traumatismes (32,3 %) ont siégé sur le rachis cervical inférieur et 25 (40,3%), à la charnière thoraco-lombaire. Au niveau cervical, 10 cas étaient classés Argenson B (16,1 %) et en thoraco-lombaire, il y avait 17 fractures Magerl A (27,4 %) et 22 Magerl B (35,5 %) avec 63,6 % d'antélisthésis. La laminectomie (59,8 %) et la corporectomie (25,8 %) avec fixation rachidienne étaient les procédures les plus pratiquées. Les suites opératoires étaient simples dans 68,4 %. Il y a eu 9 cas d'infection du site opératoire (14,5 %), 2 cas de fistules de LCS (3,2 %), 3 cas d'escarres (4,8 %) de décubitus et 5 décès (8,1%). Le score ASIA à la sortie était significativement amélioré par rapport à celui de départ dans 33,9 % de cas (p <0,001). Conclusion. Les traumatismes vertébro-médullaires consécutifs aux accidents de trafic routier demeurent des lésions assez fréquentes nécessitant un traitement chirurgical. Les jeunes de sexe masculin sont les plus touchés. Le déficit neurologique est souvent complet. La laminectomie ou la corporectomie suivies de la fixation rachidienne sont couramment réalisées avec une récupération neurologique satisfaisante dans un tiers de cas.

Therapeutic itinerary of children living with epilepsy in Kinshasa: Features, determinants, and relationships with behavioral problems and cognitive impairment.

BACKGROUND: Epilepsy mostly affects children in sub-Saharan Africa. However, little is known about the therapeutic itinerary of these children living with epilepsy (CWE). This study aimed to describe the therapeutic itinerary of CWE in Kinshasa and to analyze its relationships with clinical features, behavioral problems, and cognitive impairment. METHODS: This hospital-based study has included 104 CWE aged 6 to 17  years. The features of their therapeutic itinerary and their relationship with clinical features, behavioral problems, and cognitive impairment were analyzed. RESULTS: The vast majority of CWE (87%) has started their therapeutic itinerary by the Western medicine. The first source of information about epilepsy as well as the type of antiepileptic treatment varied with the socioeconomic status of families of CWE. The total duration of the therapeutic itinerary was shorter for the CWE who were living with both their parents (P = .038), who had generalized seizures (P = .0073) or who had no family history of epileptic seizures (P = .019). The CWE who had total behavioral problem, compared with the others, were putting more time (P = .021) to reach the Centre de Santé Mentale Telema (CSMT) after the suspicion or the diagnostic of epilepsy. The total duration of CWE who had cognitive impairment (P = .021) was longer than that of CWE who had not cognitive impairment. CONCLUSION: The therapeutic itinerary of CWE in Kinshasa began with Western medicine. The remainder of this therapeutic itinerary looks like what is described in sub-Saharan literature with the majority of CWE seeking the healing based on beliefs. This study also shows that the therapeutic itinerary of CWE was associated with socioeconomic conditions, clinical features, behavioral problems, and cognitive impairment.

Intraoperative 3T MRI for pituitary macroadenoma resection: Initial experience in 73 consecutive patients.

OBJECTIVE: To report a single-center experience with a 3T intraoperative magnetic resonance imaging (iMRI) to assess transsphenoidal microsurgery on pituitary macroadenomas. METHODS: In a dual, independent operating room (OR) magnetic resonance imaging (MRI) suite, the operating table with the anesthetized patient was moved on rail tracks once a supposed maximized resection was reached to the MRI room for intraoperative image acquisition and interpretation. After the assessment of the iMRI images, the neurosurgeon evaluated whether additional resection was still possible. The resection rates were assessed on iMRI and postoperative MRI at 3 months. RESULTS: A total of 73 macroadenomas benefited from an iMRI from March 2006 to October 2011. The gross total resection (GTR) rate at the time of the first iMRI was 58.9% (n=43). Based on the iMRI, eight patients (10.9%) underwent a second surgical resection. In 3 cases, the intraoperative imaging results were suspicious for a minor residue but not convincing enough for further surgery. Fortunately, the 3 months postoperative MRI control did not disclose any residual tumor in these cases. Finally, the GTR rate at the 3-month postoperative MRI increased to 72.6% (n=53). CONCLUSIONS: 3T intraoperative MRI offered excellent quality images. Its use during transsphenoidal microsurgery on pituitary macroadenomas led to an increase not only in the extent of tumor resection (in 8 patients) but also in the rate of radical resections (69% instead of 60%). No complications due to the iMRI procedure were observed.
