They could affect either the bony structures or the spinal cords. Mechanical instability and neurologic deficits resulting from spinal cord compression are the most common manifestations. Surgical intervention remains the most effective treatment for about 20% of patients who present with spinal cord compression. The prognosis is relatively poor. This work has as objectives to describe: the diagnostic tools, the different modalities of management and the prognostic elements of spine metastasis. Methodology: We conducted an ambispective cross-sectional descriptive study;with retrospective data collection from January 2015 to December 2021 and prospective collection from January to April 2022 in the “Neurosurgery” unit of the Yaounde Central Hospital and the “Oncology and Neurosurgery” units of Yaounde General Hospital. Result: We included 101 patients. The M/F sex ratio was 1.66. The average age of the participants was 56.44 years (±14.19 SD) with a median of 58 years. Metastatic spinal tumors were discovered in 61.39% of patients with a previously known primary tumor and 21.78% of patients had newly discovered tumors. The neurologic examination revealed a vertebral syndrome in 79.21% of cases, radicular syndrome in 60.40% and sub-lesional syndrome in 59.89%. Sensory disorders accounted for 39.60% and sphincter disorders accounted for 34.65%. According to the degree of severity, the lesions were classified as Frankel E (37.62%) followed by Frankel D (21.78%). Metastatic lesions were mostly found at the thoracic vertebrae (68.25%) and lumbar vertebrae (22.22%). The most represented primary tumors were: prostate tumors (41.58%) and breast tumors (23.76%);followed by malignant hemopathies (15.84%). Computed-tomography scan (CT-scan) was the most frequent diagnostic imaging technique used (71.28%). Analgesic treatment mostly involved level II analgesia (64.36%). High dose steroid therapy (greater than 80mg/24h) was used in more than half of the patients. Radiation therapy was performed in 24.75% of the patients, chemotherapy in 55.44% and specific surgical interventions performed in 20.79%. The most frequent surgical indication was complete motor deficit according to the Frankel classification (47.21%). One patient in four (23.76%) experienced improvement in functional prognosis with increased muscle strength after a period of 2 weeks to 5 months of treatment. About 1 in 10 patients (8.8%) rather had worsening of their neurologic status. We observed that there was a correlation between spine surgery and improvement in muscle strength (P-value less than 0.05). Patients (12) who had better recovery or preserved gait were those with partial compression (P-value = 0.0143). Four out of five patients (81.18%) of our series had an estimated survival of less than one year according to the Tokuhashi score. Conclusion: MSTs are frequent in our context. Most patients sought consultation late after the first symptoms appeared (principally back pain). The clinical examination revealed a high proportion of patients with spinal cord compression syndrome. Medical treatment was first-line for the management of pain and most patients who underwent surgical treatment had complete neurologic deficits. The functional prognosis was found to be improved by surgery and the vital prognosis depended on the Tokuhashi score, with better accuracy when the prediction is more than 12 months.展开更多

Limitations in our technical facilities, high financial cost of ultrasound-guided biopsy often prevent us from implementing the guidelines on the practice of prostate biopsy. Methods: We conducted a retrospective and cross-sectional descriptive study comparing digital-guided and ultrasound-guided transrectal prostate biopsy of 400 patients over a period of 12 years in the Yaounde Central Hospital. We reviewed files of patients who underwent digital and ultrasound guided biopsy procedures. Data was analyzed using EPI info 7.0. Parametric variables were reported as means and standard deviations and percentages and counts were used to report categorical variables. Results: Out of the 400 patients, 292 digital-guided transrectal biopsies (73%) and 108 ultrasound-guided transrectal biopsies (27%) were performed in patients who were suspected of having prostate cancer (PCa). Patients were aged between 39 to 90 years. Both procedures were effective in identifying prostate cancer. Gleason score between 2 to 10 detected prostate adenocarcinoma for 301 patients (75.2%). The complications included anal pain, rectal bleeding, hematuria and urinary tract infections, with an occurrence rate similar for both ultrasound-guided (2.25%) and digitally-guided techniques (2.5%). Seven patients (1.75%) required hospitalization for management of complications. The mortality rate was null. Conclusion: Both techniques are effective in detecting PCa with the similar complication rates. Digital-guided trans-rectal prostate biopsy still has its place in a resource-limited setting like ours.展开更多

The Rotterdam computed tomography (CT) score refined features of the Marshall score. This score was designed to categorize traumatic brain injury (TBI) type and severity in adults. The aim of our research was to evaluate the association between the Rotterdam CT scores of patients after a cranial traumatism in terms of survival. Material and methods: It was a cross-sectional and analytical study from January 2018 to March 2020, using medical records of patients suffering from cranial traumatism, received and taken in charge in the Yaounde central hospital. Results: 100 patients were retained out of 115 recruited patients. The average age was 35.20 with a sex ratio of 4.55. The Rotterdam score was between 1 and 5 with a median of 2. The overall mortality at 6 months and 1 year was 32%. With an equal score compared to European studies, we recorded significantly higher mortality. We found the sequelae in 24% of the patients. GOS ranged from 1 to 5, and survival without sequelae (GOS 1) was the most represented. There was a positive correlation between the Rotterdam score and the GOS with a Pearson correlation coefficient of +0.514. Conclusion: The death rate in Rotterdam score equals is greater in our context compared to European studies.展开更多
