Modeling surface water critical loads with PROFILE: possibilities and challenges.
The critical load concept has become a valuable tool for policymakers in the European negotiations on emission reductions. Despite the international acceptance, ongoing validation of critical load methodology is of the utmost importance to avoid a situation where the calculation results are difficult to defend. In this paper we explore the potential of using the steady state soil chemistry model PROFILE as an alternative to the Steady State Water Chemistry (SSWC) method for calculating critical loads of acidity. The hypothesis is that the uncertainty in prediction of preindustrial leaching of base cations is reduced when soil properties instead of lake chemistry are used as input data. Paleolimnological reconstructions of preindustrial lake chemistry are used to test PROFILE. As PROFILE requires soil data that are not generally available on a catchment level, we used distributions of crucial parameters from soil survey data within the vicinity of five lakes for which paleoecological pH reconstructions were available. An important concern is the characterization of catchment hydrology. A calibration of the "effective" soil depth, needed to give PROFILE predictions that coincided with paleolimnology, suggested that approximately 0.6 m of the total soil depth was hydrologically active in supplying acid neutralizing capacity (ANC) to runoff through weathering. At present, there is insufficient evidence to either recommend or reject the PROFILE model for surface water critical loads. Before such a judgement can be made, the approach presented here has to be tested for other regions, and the definition of catchment hydrology needs to be investigated further.

The effect of circumvaginal muscle (CVM) exercise.
Circumvaginal muscle (CVM) home training based on principles of exercise physiology were tested on 48 healthy reproductive-age women. The effect of CVM exercise with a resistance device in place, CVM exercise without a device, and no exercise with device in place was studied. After random assignment to home training, CVM assessment was carried out prior to and after 6 weeks of CVM training at home. Each subject served as her own control and change scores of the three groups, on CVM variables were subjected to analysis of variance. Peak maximum pressure (PMP) was significantly different for the three groups. F = 4.56, df = 2.45, p = .016. PMP of exercise without a device was significantly different from the no exercise group (Dunett's test). Analysis of measurement error between- and within-subjects showed that the inherent variability between women was approximately four times larger than the measurement error. The results support the prescription of CVM exercise to hypertrophy the CVM, and indicate that further investigation of the large variance found in the pressure data is needed.

Identification and immediate management of the oral changes associated with eating disorders.
Oral changes are often the first indication that an eating disorder is present. Although the effect of acid regurgitation on the teeth is well appreciated, other factors may also be involved. This article highlights the changes that may be observed in patients with eating disorders, together with the possible aetiological causes.

Ectodermal dysplasia in adulthood: the restorative difficulties and management.
Ectodermal dysplasia can result in a number of oral problems. As the condition is usually diagnosed in childhood, multidisciplinary specialist dental care at an early age may minimize the long-term dental complications. This article describes the restorative management of an adult patient suffering from ectodermal dysplasia for whom such support was not available, resulting in the provision of complex and highly invasive restorative treatment in adult life to provide a functional and aesthetically acceptable dentition. The various treatment options that were considered are discussed together with the details of the treatment provided.
