Published: September 2024

Background and Objective
The ablative and excision treatment procedures are effective, accessible, and affordable in resource-constrained settings, but the rollout and posttreatment follow-up are not remarkable. The outcomes of treatment procedures among women treated for precancerous lesions of the cervix have not been adequately studied in Cameroon. This study assessed the outcome of ablative and excisional treatment procedures.

Methods
This was a cross-sectional study that assessed the clinical outcome of 170 women treated for cervical precancers using ablative and excisional procedures in 2019 and 2020. Demographic and clinical data (treatment and posttreatment follow-up) were abstracted from the program registry. The data was analyzed to assess the clinical outcomes of cervical precancer treatment. The association between each independent variable and the dependent variable was examined in a simple logistic regression. All variables with p < 0.2 in the bivariate logistic regression model were subjected to a multivariable logistic model to get rid of cofounders and obtained adjustable odds ratios. The data was summarized using odds ratios, with p-value < 0.05 considered significant. All statistical analyses were performed using STATA version 17.

Results
The cervical precancer treatment effectiveness of 93.55% was disaggregated into 94.37% and 88.23% for ablative and excisional procedures, respectively, with less severe adverse clinical effects. Despite the high awareness of women on the importance and timing of posttreatment follow-up, its uptake was 54.71%. Most of the women who got pregnant after the procedures delivered live and healthy babies. Women who were HIV positive were 89% (0.89 times) [aOR = 0.11, 95%CI (0.01 0.85), p = 0.034] less likely to have effective treatment for cervical precancer when compared to HIV-negative women. Those with low-grade lesions were eight times [aOR = 8.39, 95%CI (1.10 64.06), p = 0.04] more likely to have effective treatment for cervical precancer treatment compared to those with high-grade lesions.

Conclusion and Global Health Implications
Ablative and excisional treatment procedures for cervical precancer were effective with limited adverse effects in Cameroon. Women living with HIV and those with large lesions experienced lower treatment effectiveness. Most of the women who got pregnant after the procedures delivered live and healthy babies. Posttreatment follow-up which is highly recommended because of recurrent/persistent lesions was barely above average.

Published: September 2024

Background:
We have retrospectively reviewed our series of brain tumor patients operated on using 3D IntraOperative UltraSound (IOUS) to report technical advantages and areas of improvement.

Methods:
Clinical and radiological data of patients with a diagnosis of high-grade glioma IV operated with and without IOUS were retrieved and analyzed.

Results:
We have found 391 patients operated using IOUS coupled with neuronavigation and 257 using neuronavigation standalone. We have selected a pool of 60 patients with a diagnosis of GlioBlastoma (GB), comparing two equally sized groups operated with and without IOUS, respectively. The average extent of resection (EOR) in the IOUS group was 93%, while in the control group, it was 80%. IOUS was significantly associated with improved EOR (P < 0.0004), even when accounting for other factors affecting EOR. The average overall survival (OS) was 13.4 months, and the average progression-free survival (PFS) was 7.4 months. The Cox proportional hazard model showed an advantage in OS on patients operated using the IOUS. No statistically significant effect was observed on PFS.

Conclusion:
Intraoperative ultrasound coupled with image guidance is associated with an improved EOR and possibly an improved OS. While we are aware of several limitations related to the present analysis, these data support the routine use of IOUS as a safe and reliable technology. Larger, prospective series with updated IOUS technology are desirable to verify the accuracy of these results.

Published: September 2024

Background:
Acute spinal cord infarction (SCI) is a rare ischemic vascular lesion. It is difficult to diagnose during the acute phase because the clinical features can vary widely, and the diffusion-weighted imaging of spinal cord magnetic resonance imaging (MRI) often fails to detect any obvious abnormality. The first aim of this study was to describe the SCI patients’ characteristics, evaluate the accuracy of its diagnosis tools and management, and then find the strength of the effect of spinal surgical decompression on the patient’s outcome.

Methods:
A PubMed keyword and Boolean search using (“spinal cord infarction” OR “spinal cord ischemia” AND diagnosis OR management OR outcome) returned 221,571 results by applying filters. We added 17,400 results from Google Scholar. Fourteen studies were included in the quantitative meta-analysis of mean differences.

Results:
The Time to Nadir was <6 h (56.1%), 6–12 h (30.7%), 12–72 h (5.4%), and more than 72 h (7.8%). The higher proportion of Owl’s eye findings in the MRI was reported at the cervical level (39.6%) and thoracic level (22.9%) P = 0.031. The T2DWI has a moderate accuracy (area under the curve = 0.835) in detecting the T2 hypersignal intensity (T2HSI) at the hyperacute time to NADIR (<6 h). The median modified Rankin Scale (mRS) at admission was 3 (2–3), and after a follow-up duration of 12 months (6–15.5), the median mRS was reported to be 1 (1–2). About 68.9% benefited from medical treatment and physiotherapy, whereas spinal surgical decompression was done in 22.8%. Seventy percent of the overall studies favor spinal surgical decompression, with the estimated average standardized mean difference between medical and surgical treatment being = 1.2083 (95% confidence interval: 1.0250–1.3917).

Conclusion:
The T2DWI has moderate accuracy in detecting the T2HSI at the hyperacute time (NADIR <6 h). Even though surgical decompression favored good outcomes, medical treatment with physiotherapy was mostly used for the management of SCI.

Published: September 2024

Background:
Cryptococcal infections of the central nervous system are infrequent in immunocompetent hosts and usually present as meningitis. However, a fungal mass called a cryptococcoma may form, requiring caution in therapeutic intervention. Here, we report a rare case in which treatment of intraventricular cryptococcoma in an immunocompetent patient was facilitated by rapid pathological diagnosis.

Case Description:
A 58-year-old previously healthy man was admitted to our hospital with fever, headache, and gradually worsening hearing loss over 1 month. Cerebrospinal fluid analysis showed moderately elevated levels of protein and lymphocytic cells and decreased glucose. In addition, β2-microglobulin was highly elevated. Magnetic resonance imaging showed homogeneously enhanced lesions in lateral ventricles of the left and right hemispheres and the subarachnoid space, and 18F-fluorodeoxyglucose positron emission tomography revealed abnormal uptake corresponding to the lesion. A surgical excision was performed to achieve a definitive diagnosis. Intraoperative rapid pathology, including immunohistochemistry (IHC), yielded negative results for malignant tumor, suggesting the possibility of inflammatory granuloma. Additional targeted pathological diagnosis was immediately performed. Paraffin-embedded histopathological examination showed fibrocaseous granuloma and numerous fungal spores. Cryptococcus neoformans within the granuloma were suggested by Fontana–Masson and Grocott staining and confirmed by polymerase chain reaction (PCR), leading to a diagnosis of cryptococcoma. Antifungal agents were started 3 days postoperatively. The patient has since been doing well, with no recurrence.

Conclusion:
This pathology can be difficult to distinguish from a brain tumor, so early pathological diagnosis, including rapid pathology with IHC and PCR, may be crucial.
Perspective: Risks/adverse events for epidural spinal injections
Authors: Epstein Nancy E. , Agulnick Marc A. 
Published: September 2024

Background:
Despite the lack of FDA (Food and Drug Administration) approval, cervical and lumbar epidural spinal injections are frequently performed in the US to address back pain and/or painful radiculopathy. The three major types of injections include; interlaminar/translaminar (ESI), transforaminal (TFESI), or caudal injections. Notably, most studies document little to no clear short-term, and no long-term benefits/efficacy for these injections vs. various placebos.

Methods:
More adverse events (AE) occurred with cervical© rather than lumbar (L) injections, and more severe AE were attributed to C-TFESI vs. CESI injections.

Results:
Acute post injection AE symptoms were observed immediately or within 72 post-injection hours. These symptoms included; hypotension, acute respiratory distress, chest pain, upper extremity numbness, weakness, paresthesias, paralysis, and fevers. More AE were attributed to cervical C-TFESI vs. cervical CESI. These AE included; intramedullary/cord injections, intravascular injections (i.e. vertebral artery) resulting in brain stem/cerebellar/cord strokes, epidural abscess/infection, confusion, epidural hematomas, intracranial hypotension, and/or 6th nerve cranial palsies. AE for lumbar LESI/L-TFESI included; infections/abscess, epidural hematomas/subdural hematomas, intravascular injections, cerebrospinal fluid (CSF) leaks/dural tears (DT), and intracranial/postural hypotension. Notably, the vast majority of studies showed little to no short-term, and no long-term benefits for cervical or lumbar ESI/TFESI vs placebos (i.e. mostly consisting of normal saline alone, or saline plus local anesthesia).

Conclusion:
Epidural cervical and lumbar ESI or TFESI spinal injections demonstrated minimal to no short-term, and no long-term benefits for the treatment of cervical and/or lumbar pain/radiculopathy vs. placebos. Further, more AE were observed for cervical vs. lumbar epidural injections overall, with more AE usually seen with TFESI vs. ESI procedures.

JUSTIFICATION OF METHODS OF SELECTION OF PARAMETERS OF CUTTING ORE VEINS WITHIN THE CONSTRAINTS OF THE ECOLOGICAL IMPERATIVE
Authors: Галченко Ю.П. 
Published: September 2024

Рассмотрены условия и особенности морфологии жил и масштаба отбойки, влияющие на возможности управления процессом отбойки руды с целью снижения объемов примешивания пустых пород. Впервые установлено, что при использовании взрывных скважин максимальная полнота выемки балансовых запасов криволинейных участков жил и минимальный объем твердых отходов достигается при строго определенном соотношении между глубиной скважин, радиусом кривизны отбиваемого участка жилы и величиной технологической прирезки вмещающих пород. Предложена расчетная методика управления параметрами отбойки в зависимости от геологических характеристик отбиваемого участка жилы. Методами факторного анализа было установлено, что предельная по условиям минимума потерь руды глубина взрывных скважин лимитируется, главным образом, радиусом кривизны отбиваемого участка жилы. Влияние других факторов менее заметно при малых значениях этого радиуса и становится определяющим с его увеличением.
The paper deals with the conditions and features of the morphology of veins and the scale of breaking, affecting the ability to control the process of breaking the ore to reduce the volume of mixing of waste rock. For the first time it is established that when using blast wells, the maximum completeness of the excavation of the balance reserves of curved sections of veins and the minimum amount of solid waste is achieved with a strictly defined ratio between the depth of wells, the radius of curvature of the beaten section of the core and the value of technological cutting of the host rocks. The proposed design method of control parameters for blasting depending on the geological characteristics of the beats of the plot strands. By methods of factor analysis it was found that the maximum depth of explosive wells under the conditions of the minimum loss of ore is limited, mainly, by the radius of curvature of the chipped section of the core. The influence of other factors is less noticeable at small values of this radius and becomes decisive with its increase.
