Object. Although it has been reported that awake neurosurgical procedures are well tolerated, the long-term occurrence of general psychological sequelae has not yet been investigated. This study assessed the frequency and effects of psychological symptoms after an awake craniotomy on health-related quality of life (HRQOL).Methods. Sixteen patients undergoing an awake surgery were surveyed with a self-developed questionnaire, the Posttraumatic Stress Disorder Inventory For Awake Surgery Patients, which adopts the core components of the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) posttraumatic stress disorder (PTSD) criteria. The mean time between surgery and data collection was 97.3 ± 93.2 weeks. Health-related quality of life was assessed with the 36-Item Short Form Health Survey.Results. Forty-four percent of the patients stated that they had experienced either repetitive distressing recollections or dreams related to the awake surgery, 18.8% stated persistent avoidance of stimuli associated with the awake surgery, and symptoms of increased arousal occurred in 62.5%. Two patients presented with postoperative psychological sequelae resembling PTSD symptoms. Younger age at surgery and female sex were risk factors for symptoms of increased arousal. The experience of intense anxiety during awake surgery appears to favor the development of postsurgical PTSD symptoms, while recurrent distressing recollections particularly affect HRQOL negatively.Conclusions. In many cases awake craniotomy is necessary to preserve language and motor function. However, in some cases awake craniotomy can lead to postoperative psychological sequelae resembling PTSD symptoms. Therefore, possible long-term effects of an awake surgery should be considered and discussed with the patient when planning this type of surgery.
Objective: Recent observational studies have established progression and recurrence rates of pituitary adenomas. However, it is still unknown how individual pituitary adenomas grow over years and whether growth kinetics follow a distinct growth model. The objective of this study was to define a growth model for non-functioning pituitary adenomas. Methods: Fifteen patients who had five or more serial high-quality examinations with magnetic resonance images or computerized tomography scans were identified among 216 patients with nonfunctioning pituitary adenomas. Tumour volumes were assessed using a stereological method based on the Cavalieri principle. Tumour growth during the observation period was analysed and different growth models were fitted to the data. Results: Fifteen pituitary adenomas (12 recurrent tumours and 3 newly diagnosed tumours) were longitudinally observed during a median observation period of 7.4 years (range: 2.3-11.9 years). Growth kinetics could be described either by an exponential growth model (nine patients) or by a logistic model (five patients) with initial exponential growth followed by deceleration of growth. One tumour remained unchanged in size during the observation period. None of the adenomas showed accelerated growth during the observation period. Overall, the linear growth model was not suitable to describe the growth kinetics of non-functioning pituitary adenomas. Conclusions: Our study shows that growth of pituitary adenomas can be described by distinct growth models. Knowledge of growth dynamics has implications for clinical practice and helps to adjust scanning protocols for follow-up investigations.
Similar to several studies in non-pituitary patient cohorts (e.g., patients with multiple sclerosis or lower back pain), our results indicate that psychosocial impairment in CD is significantly influenced by how the patient deals with the illness. Therefore, psychological training of positive coping styles could be a helpful complementary therapy in the overall treatment strategy of CD.
The Tuebingen CD-25 is a valid and reliable instrument to evaluate HRQoL in CD. Based on impairment of HRQoL for the different subdimensions, specific support can be offered to the patients.
With our microsurgical concept, a high initial cure rate is achievable with minimal surgical morbidity. Enlarged adenomectomy has no adverse effect on the rate of postoperative hypopituitarism. Early repeat surgery is a successful option if CD persists.
