Endonasal Approach for Nasal and Paranasal Sinus Tumor Removal
2001
Patients with benign (53) and malignant (22) tumors of the nose and paranasal sinuses were treated for tumor removal via an endonasal approach. Patient selection was based on tumor location (centrally) rather than histology. Tumors attainable by the endonasal approach were located in the nasal cavity, the ethmoid sinus, the sphenoid sinus and the medial wall of the maxillary sinus. Endonasal microscopic techniques including endonasal orbital decompression and endonasal closure of CSF-leaks were combined with surgical navigation tools in selected cases. Surgical trauma and morbidity could be minimized without compromising radicality of tumor removal. Postoperative hospitalization was compara…
A comparison of mothers’ and fathers’ experiences of the attachment process in a neonatal intensive care unit
2008
Aim. To compare mothers’ and fathers’ individual views and experiences of the attachment process in a neonatal intensive care unit within the first week after a premature birth. Background. The attachment between parents and children is a precursor to the consolidation of parenting skills, the growth and development of the infant and the establishment of a bond between parent and child. Premature birth and the resultant hospitalization disrupt the normal attachment process between parent and child. Most of the litteraure on attachment theory focuses on the mother–child connection and is being criticised for regarding the father's role as supportive and peripheral. Methods. The design of …
High striatal occupancy of D2-like dopamine receptors by amisulpride in the brain of patients with schizophrenia.
2003
The 'atypicality' of the antipsychotic drug, amisulpride, has been attributed to preferential extrastriatal binding. Previous investigations of striatal D2 receptor occupancy by amisulpride revealed conflicting results. The aim of this PET study was to measure the striatal occupancy by amisulpride and to correlate it with the corresponding drug plasma concentrations. Nine amisulpride-treated patients and 12 healthy volunteers serving as controls were studied with PET and [18F]desmethoxyfallypride. Occupancy values and plasma concentrations were nonlinearly fitted to an E max model. Results showed 43-85% (putamen) and 67-90% (caudate) D2-like receptor occupancy. Plasma amisulpride concentrat…
Subchronic Effects of Olanzapine on Sleep EEG in Schizophrenic Patients with Predominantly Negative Symptoms
2004
Background It is well known that sleep disturbance is an integral symptom of schizophrenia. In recent studies, a deficit of delta sleep has been observed in schizophrenic patients. Antipsychotic drugs with serotonin (5-HT2) receptor-antagonistic properties are considered to have delta sleep promoting effects. We have investigated the effects of subchronic olanzapine treatment on sleep EEG in schizophrenic patients. Methods The effects of administration of olanzapine (15 to 20 mg) on sleep were studied for four weeks in 10 male, drug-free patients suffering from schizophrenia with predominantly negative symptoms. Conventional sleep EEG parameters were investigated at baseline and after treat…
Treatment of Metachronous and Simultaneous Liver Metastases of Pancreatic Cancer
2009
<i>Aim:</i> Patients were analyzed who underwent treatment of liver metastases from pancreatic cancer. <i>Methods:</i> Selection criteria were the possibility of R0 resection of the primary and/or the liver metastases, no other sites of metastases, and the presentation of liver metastases. A comparison of treatment by surgery versus chemotherapy regarding overall survival and disease-free interval was performed. <i>Results:</i> Between 1996 and 2008, a total number of 23 patients were retrospectively identified from a prospective database of 193 cases of pancreatic cancer. In 14 cases, liver metastases were found simultaneously, and in 9 cases metachronou…
High prevalence of BRCA1 deletions in BRCAPRO-positive patients with high carrier probability.
2007
Mutation screening of the BRCA1 and BRCA2 genes in probands with familial breast/ovarian cancer has been greatly improved by the multiplex ligation-dependent probe amplification (MLPA) assay able to evidence gene rearrangements not detectable by standard screening methods. However, no criteria for selection of cases to be submitted to the MLPA test have been reported yet. We used the BRCAPro software for the selection of familial breast/ovarian cancer probands investigated with the MLPA approach after negative BRCA1/2 conventional mutation screening. One hundred and seventy-seven probands were investigated for germline BRCA1/2 mutations after assessment of genetic risk using BRCAPro. Proban…
Nocturnal oxygen enrichment in sleep apnoea.
2000
We hypothesized that a modest oxygen enrichment, rather than 100% oxygen supplementation as used in previous trials, could result in improvement in ventilatory and cardiac symptoms, in patients with obstructive sleep apnoea (OSA), without jeopardizing the chemostimulant ventilatory drive. This hypothesis was tested in five male patients with OSA in a single-blinded trial consisting of one night spent sleeping in control room air (control night), followed by one night spent sleeping while exposed to air with a 9% enriched oxygen content (oxygen-enriched night). Oxygen enrichment resulted in a significant shift in the oxygen saturation profile towards values of ≥ 95% and to decrease desatura…
Acute performance evaluation of a new ventricular automatic capture algorithm
2006
Aims This study evaluated the acute clinical performance of a new ventricular automatic capture algorithm developed to work with all lead types and pacing vectors. Methods and results During regular pacemaker implant or replacement, AutoThreshold and manual threshold tests were performed in ventricular unipolar (UP) and bipolar (BP, if applicable) pacing using a customized external prototype INSIGNIA™ pacemaker. The success rate and accuracy of two different modes (commanded and ambulatory) of the automatic capture algorithm were used to evaluate the performance. Loss-of-capture events (two consecutive non-captured beats without backup pacing) were used to assess safety. Data of 53 patients…
Associations of parental physical activity trajectories with offspring's physical activity patterns from childhood to middle adulthood : The Young Fi…
2022
We investigated the association of parental physical activity (PA) trajectories with offspring's youth and adult PA. Self-reported PA data were extracted from the Young Finns Study with three follow-ups for parents between 1980 and 1986 and nine follow-ups for their offspring in youth between 1980 and 2011 (aged 9-39 years, n = 2402) and in adulthood in 2018. Accelerometer-derived PA was quantified in 2018-2020 (aged 43-58 years, n = 1134). Data were analyzed using mixture models and conducted in 2022. We identified three trajectories for fathers and mothers (high-stable activity, 20.2%/16.6%; moderate-stable activity, 50.5%/49.6%; and low-stable activity, 29.4%/33.7%) and four for youth ma…
Functional pain in hospitalised and school children
2012
Aim. Aim of the study was to recognise the role of psychological disagreement in children and adolescents suffering from functional pain. Methods. Two groups of children, adolescents and their parents were interviewed: group H (hospitalized patients), group S (students, at school). Suitable investigations excluded organic lesions. The following data were analysed: 1) presence of pain in relation with: i) sex and age; ii) relation with parents, brothers, other relatives, schoolfellows; 2) efficacy of possible treatments. Results. Group H: 194 patients, median age 10 years; 134 referred pain: 62 out of 92 males and 72 out of 102 females; location of pain: abdomen, limbs, head, back. Family di…
