Chemotherapy-Related Encephalopathy With Super-Refractory Status Epilepticus in a Child With Osteosarcoma: A Case Report With a Review of Literature

Management of Cisplatin-Induced Encephalopathy: A Case Report and Literature Review

Cisplatin is a cancer therapy drug commonly used. It is well-known for its antineoplastic properties, as well as for its numerous adverse effects, particularly its neurotoxicity. Symptoms associated with a central nervous system injury are unusual but can present a diagnostic challenge. Here, we report a case of a 62-year-old patient who was diagnosed with undifferentiated nasopharyngeal carcinoma. Cisplatin-based chemotherapy was administrated. Five days following the second cycle of treatment, the patient presented neurological disorders. A full biological workup and brain imaging were requested and revealed no abnormalities. The diagnosis of cisplatin encephalopathy was then suspected. Twenty days after cessation of cisplatin therapy, the neurological symptoms began to improve. Based on our case and a review of the literature, cisplatin-induced encephalopathy remains unusual. Its diagnosis is based on a combination of clinical, biological, and radiological criteria and requires the exclusion of other etiologies for neurological disorders in a patient being treated for cancer. Treatment is symptomatic and depends on stopping cisplatin therapy. These neurological adverse effects are often transitory and disappear without major repercussions.

A Bibliometric Analysis and Visualization of Current Research Trends in Chinese Medicine for Osteosarcoma

BACKGROUND

To illustrate the research framework, overall knowledge structure, and development trends of Chinese medicine (CM) treatment for osteosarcoma (OS) by using a bibliometric analysis and newly developed visualization tools.

METHODS

Research datasets were acquired from the Web of Science (WOS) database from January 1, 1980 to September 30, 2019. VOS viewer and Citespace software was used to analyze the data and generate visualization knowledge maps. Annual trends of publications, distribution of institutes, distribution of journals, citation and H-index status, co-authorship status, research hotspots and co-citation status were analyzed.

RESULTS

A total of 223 publications in the WOS database met the requirement. The number of published articles showed a rise but the citation frequency and the H-index of China were relatively low. The cooperation between the countries, institutes and authors were relatively weak. Most publications were basic researches. Most of the previous researches focused on basic mechanisms of CM in treating OS, and therapy and improvement of dosage form may become a frontier in this research field.

CONCLUSIONS

Compared with other fields, the field of CM treatment for osteosarcome is still in infancy. The distribution of researches is imbalanced and cooperation between countries, institutions and authors remains to be strengthened. Furthermore, basic research occupies an absolute dominant position, and the exploration of the molecular mechanism of CM in preventing and treating OS may become a key point in the future.
