ABSTRACT

BACKGROUND: Elderly patients with symptomatic benign intracranial tumours such as meningioma pose particular problems in decision making. We report on the outcome, morbidity and mortality in patients aged over 80 years after undergoing cranial surgery for meningiomas. METHODS: In this retrospective study, 37 patients aged more than 80 years underwent surgery at our neurosurgery department. The Karnofsky Performance Scale (KPS) was used to assess functional status. The American Society of Anesthesiologists (ASA) classification system, the Geriatric Scoring System, the Clinical-Radiological Grading System and the Sex, Karnofsky, ASA, Location and Edema score were used to define clinical status and tumour characteristics. The Charlson Comorbidity Index and Clavien-Dindo classification scores reflected therapeutic morbidity. RESULTS: Preoperative KPS scores were generally higher than 60 (n = 32). Of the 37 patients, 24 (64.8%) were in ASA class I or II, and 27 (73.0%) had one or more comorbidities. The median length of follow-up was 80.0 months (range: 1-96 months). The 1-year mortality rate was 2.7% (n = 1). Tumour control was achieved in 33 patients. At discharge, KPS scores were improved in 21 patients (with an average gain of +18.1 ± 8.7), stable in 10 patients and poorer in 6 patients. KPS scores improved or were stable in patients with shorter lengths of hospital stay (15.5 ± 17.9 days vs 51.4 ± 25.4 days; p < 0.01), those with Clavien-Dindo scores lower than 2 (p < 0.01) and those with less favourable preoperative KPS scores (69.4 ± 10.9 vs 82.0 ± 11.0; p = 0.04). CONCLUSION: Historically, surgery for intracranial meningiomas in patients aged >80 years has been feasible; this series demonstrated decreasing rates of postoperative mortality. Functional benefit should be the main goal of surgery. Perioperative morbidity should be better assessed and predicted because it significantly influences functional outcomes.

ABSTRACT

BACKGROUND: The pathophysiologies underlying meningioma and glioma are distinct. The coexistence of those 2 lesions in the same patient is rare, and at the same location, it is even more exceptional. CASE DESCRIPTION: We report a case of a 79-year-old man initially presenting with a meningioma that was treated by complete excision of the lesion. The patient had 2 relapses at the same site, in which glioblastoma was confirmed histopathologically. CONCLUSIONS: Glial transformation meningiomas remain a contentious issue, with coincidental occurrence being the most prevalent explanation. Nevertheless, impairment of the same molecular signaling pathways in both tumor types suggests a common origin. Another hypothesis is that perilesional parenchymal damage from radiotherapy or surgery may lead to glial transformation in the tissues surrounding the original meningioma lesion. Further research is needed to determine if the original tumor or surgery has an oncogenic effect on the adjacent tissue.

ABSTRACT

Hypohidrosis is a frequent and early symptom in patients with Fabry disease. Studies have reported improved sweating in patients treated with enzyme-replacement therapy. A new method, Sudoscan, has been developed that is noninvasive, is quantitative, and can quickly evaluate sweat gland function. It is based on the electrochemical reaction between sweat chlorides and stainless-steel electrodes in contact with the palms and soles. The aim of our study was to evaluate the Sudoscan as a tool to assess sudomotor dysfunction in patients with Fabry disease. Consecutive patients were prospectively recruited who had a diagnosis of Fabry disease, which had been confirmed genetically and/or by measurement of α-galactosidase activity in leukocytes. Healthy controls, matched (1:1) for age and sex, were also enrolled. Test results were expressed immediately as electrochemical skin conductance (ESC, µS) for hands and feet. Sudomotor dysfunction was considered absent, moderate, or severe if the ESC measured on the feet was >60 µS, between 60 and 40 µS, or <40 µS, respectively. Among the 18 patients, 11 had hypohidrosis or anhidrosis. Hand and feet ESCs were significantly lower in patients compared to their controls (P=0.0015 and P=0.0047, respectively). Among patients, 8/18 (44.5%) had a sudomotor dysfunction, moderate in three and severe in five cases. Hand and feet ESCs were significantly lower in those with hypohidrosis/anhidrosis compared to those without (P=0.0014 and P=0.0056, respectively). This study showed that Sudoscan provided a quick, noninvasive, and quantitative measurement of sudomotor function in Fabry disease patients.
