Cervical cancer (CC) is the leading cause of cancer-related death among women in sub-Saharan Africa, primarily because of limited access to effective screening and preventive treatment. Our aim was to assess the feasibility of a human papillomavirus (HPV)-based CC screen-and-treat approach in a low-resource context. We recruited 1012 women aged 30-49 years through a CC screening campaign conducted in the District Hospital of Dschang, Cameroon. Participants performed HPV self-sampling, which was tested for high-risk HPV (HR-HPV) DNA using the point-of-care Xpert HPV assay...

On May 16, 1914, The Lancet Journal published a paper by Romuald Węgłowski, a Polish-born professor of Moscow University, entitled "Malignant tumours of bones: a new method in conservative operative treatment." The idea of biological resection presented in the paper consisted in thermocoagulation of the apparently cancerous part of a bone with a jet of steam. According to the author, dead bone rid of live malignant cells reconstructed itself quickly, which helped to preserve the functionality of the organ without considerable limitations...

INTRODUCTION: Dysembryoplastic neuroepithelial tumors and gangliogliomas are developmental glioneuronal tumors usually revealed by partial epilepsy. High epileptogenicity, childhood epilepsy onset, drug-resistance, temporal location, and seizure freedom after complete resection are common characteristics of both tumors. We report the specificity of surgical management, functional results and seizure outcome in cases of a tumor location in eloquent areas. METHODS: Among 150 patients (88 males, 3-55 years) operated on for refractory epilepsy due to a glioneuronal tumor (1990-2015), 30 (20%, dysembryoplastic neuroepithelial tumors=21; gangliogliomas=9) had a tumor located in an eloquent cortex (sensory-motor, insular or language areas)...

Besides other innovative stereotactic procedures (radiofrequency thermocoagulation, focused ultrasound, gamma knife) laser interstitial thermotherapy (LiTT) provides minimally invasive destruction of pathological soft tissues which could be especially relevant for epilepsy surgeries involving adult and pediatric patients. Unlike standard resections, no craniotomy is required; just a tiny borehole trepanation is sufficient. Damage to cortical areas when accessing deep lesions can be minimized or completely avoided, and treating epileptogenic foci near eloquent or even vital brain areas becomes possible...

The rationale and the surgical technique of stereo-electroencephalography (SEEG)-guided radiofrequency thermocoagulation (RF-TC) in the epileptogenic zone (EZ) of patients with difficult-to-treat focal epilepsy are described in this article. The application of the technique in pediatric patients is also detailed. Stereotactic ablative procedures by RF-TC have been employed in the treatment of epilepsy since the middle of the last century. This treatment option has gained new popularity in recent decades, mainly because of the availability of modern imaging techniques, which allow accurate targeting of intracerebral epileptogenic structures...

Objective. : Idiopathic trigeminal neuralgia (ITN) can be effectively treated with radiofrequency thermocoagulation. However, this procedure requires cannulation of the foramen ovale, and conventional cannulation methods are associated with high failure rates. Multimodality imaging can improve the accuracy of cannulation because each imaging method can compensate for the drawbacks of the other. We aim to determine the feasibility and accuracy of percutaneous foramen ovale cannulation under the guidance of virtual navigation with multimodality image fusion in a self-designed anatomical model of human cadaveric heads...

Focal therapy involving destruction of prostate specific region containing a clinically meaningful tumor is a new treatment for prostate cancer. Despite the absence of long-term results of applying this method of treatment, there are prerequisites that allow to consider focal therapy as a method with a lower risk of side effects typical of conventional treatment. Focal laser thermocoagulation is a developing technique with a number of advantages, the most important of which is the ability to perform the treatment under the real-time magnetic resonance imaging control...

In common with other stereotactic procedures, stereotactic laser thermocoagulation (SLT) promises gentle destruction of pathological tissue, which might become especially relevant for epilepsy surgery in the future. Compared to standard resection, no large craniotomy is necessary, cortical damage during access to deep-seated lesions can be avoided and interventions close to eloquent brain areas become possible. We describe the history and rationale of laser neurosurgery as well as the two available SLT systems (Visualase® and NeuroBlate®; CE marks pending)...
