RESUMEN
Patient-reported outcome measures (PROMs) are validated tools that are widely utilized in research and patient care. Their diversity, quality, and application remain matters of peak research interest. This article is a review of the PROMs that were utilized in high-impact publications in the neurospine surgical literature. The 50 most cited articles on the subject were selected and analysed. Most (42 articles) were published in spine journals and, in particular, in the journal Spine (Phila Pa 1976) (28 articles). A total of 34 PROMs were utilized, of which 24 were used only once in single studies. The four most common PROMs were Scoliosis Research Society-22 (SRS-22) (15 articles), Short Form-12 and Short Form-36 (SF-12 and SF-36) (11 articles), Ronald-Morris Disability Questionnaire (RMDQ) (nine articles), and Oswestry Disability Index (ODI) (five articles). Nineteen articles focused on validating translated versions of 11 PROMs to other languages. The languages that had the maximal number of tools translated to amongst the highly cited articles were Italian (six tools), Portuguese (four tools), German (three tools), and Japanese (three tools). The most common diagnoses and the PROMs used for them were back pain and cervical spine disorder (SF-12 and SF-36 (nine articles), RMDQ (eight articles), and ODI (five articles)), and idiopathic scoliosis (SRS-22) (14 articles)). The median (range) article citation number was 137 (78-675). The four most cited PROMs were SRS-22 (2,869), SF-12 and SF-36 (2,558), RMDQ (1,456), and ODI (852). Citation numbers were positively impacted by article age and participant number but not by tool type or clinical diagnosis. In conclusion, a wide range of PROMs was utilized in the 50 most cited publications in the neurospine surgical literature. The majority were disease-specific rather than generic and targeted particular spine pathology. Neurosurgical PROMs were under-represented amongst the most cited articles. Awareness of the PROMs used in high-impact studies may be helpful in tool selection in future research. PROMs are valuable in standardizing subjective outcomes. Their use in research and clinical settings in any validated language is highly encouraged.
RESUMEN
OBJECTIVES: To examine the factors that influence country self-citation rate (SCR) in clinical neurology and to assess the impact of self-citation on the ranking of the top 50 countries. METHODS: SCImago Journal & Country Rank was used to collect data for the 50 most cited countries in clinical neurology during 1996-2019. Country SCR was correlated with several productivity parameters and examined statistically. Countries that dropped in their ranking after the exclusion of self-citations were identified. RESULTS: The median (range) country SCR for the 50 most cited countries was 11.3%.(5.3%- 47%). Country SCR correlated significantly with total citable documents and total cites numbers and rankings. The exclusion of self-citations led to a drop in the ranking of 8(16%) countries only. No significant difference between the total and net total cites rankings was observed. CONCLUSIONS: Self-citation can be appropriate and reflect an expansion on earlier research. Highly cited productive countries tend to have high country SCR. Excluding self-citations had minimal impact on the ranking of the top 50 countries. Our findings indicate that self-citation is unlikely to influence country standing amongst the top 50 and does not support the argument for eliminating self-citations from citation-based metrics. A more globalization through international collaboration in research is encouraged.
RESUMEN
The occurrence of pseudotumor cerebri (PTC) and hyperprolactinemia related to a prolactinoma are extremely rare, and the link between these pathologies has not been examined adequately in the post-MRI era. We report a patient with a small intrasellar prolactinoma who also developed PTC. Magnetic resonance venography did not show any evidence of compression of the cavernous or any other sinuses. She initially responded to treatment with acetazolamide and cabergoline. However 9 months later, her PTC symptoms recurred despite a normal serum prolactin level and a mild reduction of the pituitary tumor size on MRI. She improved after a lumboperitoneal shunt. We conclude that the findings in our patient do not support an association between PTC and hyperprolactinemia or prolactinoma. However, the case supports the need for clinicians to consider the diagnosis of PTC when patients with small pituitary lesions exhibit raised intracranial pressure features.

Choroid plexus papilloma (CPP) is primarily found in children less than 2 years of age but can also be diagnosed prenatally. The presentation of a large CPP during infancy is not uncommon and surgical excision is usually recommended without delays. As a result, information about the growth rate of CPP during infancy is lacking. We report a preterm infant who presented with a choroid plexus papilloma that grew from being undetected on MRI to reaching a large size in 5 months. The case is unique in that it provides documentation of the rapid growth potential of this benign tumour in infancy. A possible explanation for this occurrence is discussed.
