- Results from a follow-up of all patients with Cushing's syndrome who visited the Division of Endocrinology at Sahlgrenska University Hospital, Göteborg, Sweden, during 1997-1998 revealed 28 patients with ACTH-dependent disease and 3 with ACTH-independent disease. Female/male ratio was 4:1 with mean age at diagnosis 30 years. Mean time from first symptoms to diagnosis was three years (range 0-8). The most frequent signs were hypertrichosis, easy bruising, hypertension, osteoporosis and diabetes mellitus. Out of the 28 patients with ACTH-dependent disease, 16 underwent more than one treatment method (transcranial/transsphenoidal pituitary surgery, pituitary irradiation, adrenalectomy), 26 were cured and 25 developed hormonal deficiencies after treatment. Five of the 11 patients who underwent adrenalectomy developed Nelson tumors. All patients in the ACTH-independent group were cured after unilateral adrenalectomy.

- OBJECTIVE Despite ample experience in surgical treatment of pituitary adenomas, little is known about objective indices that may reveal risk of visual impairment caused by tumor growth that leads to compression of the anterior visual pathways. This study aimed to explore diffusion tensor imaging (DTI) as a means for objective assessment of injury to the anterior visual pathways caused by pituitary adenomas. METHODS Twenty-three patients with pituitary adenomas, scheduled for transsphenoidal tumor resection, and 20 healthy control subjects were included in the study. A minimum suprasellar tumor extension of Grade 2-4, according to the SIPAP (suprasellar, infrasellar, parasellar, anterior, and posterior) scale, was required for inclusion. Neuroophthalmological examinations, conventional MRI, and DTI were completed in all subjects and were repeated 6 months after surgery. Quantitative assessment of chiasmal lift, visual field defect (VFD), and DTI parameters from the optic tracts was performed. Linear correlations, group comparisons, and prediction models were done in controls and patients. RESULTS Both the degree of VFD and chiasmal lift were significantly correlated with the radial diffusivity (r = 0.55, p < 0.05 and r = 0.48, p < 0.05, respectively) and the fractional anisotropy (r = -0.58, p < 0.05 and r = -0.47, p < 0.05, respectively) but not with the axial diffusivity. The axial diffusivity differed significantly between controls and patients with VFD, both before and after surgery (p < 0.05); however, no difference was found between patients with and without VFD. Based on the axial diffusivity and fractional anisotropy, a prediction model classified all patients with VFD correctly (sensitivity 1.0), 9 of 12 patients without VFD correctly (sensitivity 0.75), and 17 of 20 controls as controls (specificity 0.85). CONCLUSIONS DTI could detect pathology and degree of injury in the anterior visual pathways that were compressed by pituitary adenomas. The correlation between radial diffusivity and visual impairment may reflect a gradual demyelination in the visual pathways caused by an increased tumor effect. The low level of axial diffusivity found in the patient group may represent early atrophy in the visual pathways, detectable on DTI but not by conventional methods. DTI may provide objective data, detect early signs of injury, and be an additional diagnostic tool for determining indication for surgery in cases of pituitary adenomas.

Tumour recurrence and enlargement in patients with craniopharyngioma with and without GH replacement therapy during more than 10 years of follow-up.

Journal article (peer-reviewed)abstract
- Most patients who have been treated for craniopharyngioma (CP) are GH deficient (GHD). GH replacement therapy (GHRT) may stimulate tumour regrowth; and one of the concerns with long-term GHRT is the risk of tumour progression. Therefore, the objective was to study tumour progression in CP patients on long-term GHRT.Case-control study.The criteria for inclusion of cases were: i) GHD caused by CP; ii) GHRT >3 years; and iii) regular imaging. This resulted in 56 patients (mean age at diagnosis 25±16 years) with a mean duration of GHRT of 13.6±5.0 years. As controls, 70 CP patients who had not received GHRT were sampled with regard to follow-up, gender, age at diagnosis and initial radiation therapy (RT).The 10-year tumour progression-free survival rate (PFSR) for the entire population was 72%. There was an association (hazard ratio, P value) between PFSR and initial RT (0.13, 0.001) and residual tumour (3.2, 0.001). The 10-year PFSR was 88% for the GHRT group and 57% for the control group. Substitution with GHRT resulted in the following associations to PFSR: GHRT (0.57, 0.17), initial RT (0.16, <0.001), residual tumour (2.6, <0.01) and gender (0.57, 0.10). Adjusted for these factors, the 10-year PFSR was 85% for the GHRT group and 65% for the control group.In patients with CP, the most important prognostic factors for the PFSR were initial RT and residual tumour after initial treatment. Long-term GHRT did not affect the PFSR in patients with CP.

- Primary objective: Life expectancy may be substantially reduced for many years after severe traumatic brain injury (TBI). This study investigated the patterns of the short-and long-term all-cause mortality and the rates of primary causes of death in patients with severe TBI. Subjects: This study was of 166 consecutive patients (6-82 years) with severe TBI admitted to Sahlgrenska University Hospital, Gothenburg, Sweden, from 1999-2002. The control group consisted of 809 subjects from the community, matched to the TBI cohort for age, gender and postcode area at the time of the injury. Methods: Survival outcome and cause of death were ascertained 10 years after the injury from the Swedish National Board of Health and Welfare register. The cumulative death rates and causes of death in cases and controls were compared. Results: The risk of death was increased for at least 10 years after severe TBI. The distribution of the causes of deaths differed between cases and controls in the first year of follow-up, but not between 1-year survivors and controls. Conclusion: Further research will be required to determine how to improve treatment so as to lower late mortality among survivors of severe TBI.
