[Psychological comorbidity and quality of life of patients with morbid obesity and requesting gastric banding].
Bariatric surgical operations are well established in the treatment of morbid obesity. In this study, 79 consecutive applicants for laparoscopic gastric banding (60 females with a mean BMI of 47.4 kg/m2 and 19 males with a mean BMI of 48.9 kg/m2, mean age 39.6 years) were examined preoperatively by structured psychiatric interview and questionnaire.

Review[Mucous clearing respiratory-physiotherapy in pediatric pneumology].
Chest physiotherapy for mucus clearance may be seen as a therapeutic application of respiratory physiology; the basic mechanical principles do not differ between the treatment of paediatric and adult patients. However, children present with a developmentally defined, age-specific situation regarding respiratory structure and function that calls for a specialised therapeutic approach. Inspiration dilates bronchi and thus brings air behind obstructing mucus plugs. ⋯ However, lateral decubitus position does not affect ventilation in children in the same way as in adults. Disease-inflicted changes of structure and function call for further modification of the therapeutic approach. Finally, the psychology of therapist-patient interaction differs substantially between different age groups.

Review[Recent development in the treatment of lung cancer: from the point of view of the medical oncologist].
After a short introduction to recent developments in the field of tobacco control, the non-surgical treatment of small cell and non-small cell lung cancer is summarised with special reference to practical aspects. The promising results obtained with newer cytostatic agents are reviewed. In small cell lung cancer, modern chemotherapy prolongs survival five-fold to an average of one year and 5-10% of all patients achieve long-term disease-free survival. ⋯ Newer cytostatic agents such as the taxanes, vinorelbine and gemcitabine are highly active. These agents are currently incorporated into new, highly active combination chemotherapies. Whether these newer polychemotherapies will bring a significant improvement awaits the results of future randomised trials.

Functional MR imaging of the craniocervical junction. Correlation with alar ligaments and occipito-atlantoaxial joint morphology: a study in 50 asymptomatic subjects.
Whiplash injuries are frequent in industrialized countries. The acute and chronic symptoms following such injuries are incompletely understood and objective clinical or imaging findings are rare. Several authors have suspected that rear end collisions occurring when the head is rotated may result in tears of the alar ligaments. There has been experimental proof that a torn alar ligament increases the rotation of the C0/C1 and C1/C2 segments to the contralateral side. Functional cross sectional imaging has therefore been proposed to diagnose injuries of the alar ligaments. So far, published data on normal ranges of rotation in an asymptomatic population have been sparse. The aim of this study was to determine by MR imaging the normal range of rotation in the first three cervical segments and their relation to the morphology of the alar ligaments and the occipito-atlantoaxial joints. ⋯ There is wide variation of segmental motion in the upper cervical spine. Differences in right-to-left rotation are frequently encountered in an asymptomatic population. Therefore, these measurements are unsuitable for indirect diagnosis of soft tissue lesions after whiplash injury and should not be used as a basis for treatment guidelines.

Continuous monitoring of liver oxygenation with near infrared spectroscopy during naso-gastric tube feeding in neonates.
Near infrared spectroscopy (NIRS) is a non-invasive method of estimating the haemoglobin concentration changes in certain tissues. It is frequently used to monitor oxygenation of the brain in neonates. At present it is not clear whether near infrared spectroscopy of other organs (e.g. the liver as a corresponding site in the splanchnic region, which reacts very sensitively to haemodynamic instability) provides reliable values on their tissue oxygenation. ⋯ The test-retest variability for intra-individual measurements was 2.7 +/- 2.1%. After bolus feeding the tissue oxygenation index of the liver increased as expected. This indicates that near infrared spectroscopy is suitable for monitoring changes in tissue oxygenation of the liver in newborn infants.
