Does persistent crossover (ipsilateral) motor evoked potential (MEP) responses represent a technical failure for intracranial motor tract monitoring? A case example and practical solution.

Article Synopsis
- Attention to the intensity of motor evoked potentials (MEPs) is crucial to avoid false negatives during intracranial surgeries; the presence of crossover MEP responses may misleadingly indicate excessive stimulation intensity.
- A case study involving a patient undergoing tumor resection illustrated that using MEP onset latencies helped accurately determine appropriate stimulation intensity, even when crossover responses occurred.
- The results indicated that using onset latency measurements effectively validated contralateral hand MEPs for reliable intraoperative monitoring, leading to a successful surgery without motor deficits.
Standard- versus extended-duration anticoagulation for primary venous thromboembolism prophylaxis in acutely ill medical patients.

Background: Venous thromboembolism (VTE) includes two interrelated conditions, deep vein thrombosis (DVT) and pulmonary embolism (PE). Risk factors include dehydration, prolonged immobilization, acute medical illness, trauma, clotting disorders, previous thrombosis, varicose veins with superficial vein thrombosis, exogenous hormones, malignancy, chemotherapy, infection, inflammation, pregnancy, obesity, smoking, and advancing age. It is estimated that hospitalized patients are 100 times more likely to develop VTE and, compared with surgical patients, medical patients often have more severe forms of VTE.

Endovascular treatment of lower-extremity peripheral disease (PAD) is associated with higher complication rates and suboptimal outcomes in women. Atherectomy has shown favourable outcomes in calcified lesions, minimising the incidence of stent placement caused by recoil or flow-limiting dissection. To date, there are no published mid-term outcomes evaluating the performance of atherectomy differentiated by sex.

Cavernous malformations (CMs) are rare, often oligosymptomatic vascular lesions. Common manifestations include seizures and focal neurological deficits. Depending on the symptoms, location, size, and risk factors of bleeding, such as the presence of a developmental venous anomaly, the injury can be highly morbid.

Photodynamic therapy is an approved treatment for primary, superficial, and small nodular basal cell carcinomas with a thickness of < 2 mm located on low-risk sites. Histologically verified basal cell carcinomas clinically assessed as suited for photodynamic therapy were included. The study aimed to investigate the agreement between clinical and histological assessments of basal cell carcinoma subtypes and thickness of tumours selected for photodynamic therapy with histopathological evaluation as a reference.
