RESUMEN
OBJECTIVE: Parents of children with developmental malformations of different kinds are vulnerable to many consequences of the experienced stress and attempts to cope with it. The aim of the study was to determine the psychological correlates of affect for parents of such children. PATIENTS AND METHODS: The study included 78 respondents: 69 women and 9 men, aged between 20 and 45, all of them parents of children with craniofacial malformations who had their routine check-ups at an orthodontics clinic. The respondents were evaluated using pencil-and-paper questionnaires, the same survey set for all respondents. The following tools were used in the study: the Inventory for Measuring Coping with Stress (Mini-COPE), the Family Resilience Assessment Scale (FRAS), and the Positive and Negative Affect Schedule (PANAS). The guardians' demographic data and the details of the child's medical history were gathered using a questionnaire constructed for the purposes of the study. RESULTS: The present study confirmed significant correlations between affect and preferred stress coping strategies, as well as between affect and family resilience. Coping strategies and family resilience, treated as a resource, were also significantly correlated in the group of respondents. CONCLUSIONS: Mental resilience is an important resource contributing to effective stress coping in a situation where a child suffers from malformation.

OBJECTIVE: The description of clinical manifestation of hearing problems in cleidocranial dysplasia (CCD) remains limited and incomplete, since CCD constitutes a rare congenital disorder. The study aims to provide a complex panel analysis of the auditory system in patients suffering from the disease. PATIENTS AND METHODS: The study group consisted of 4 children with CCD (aged: 12-15), who underwent orthodontic treatment. A full panel analysis of their auditory systems was performed, including high-frequency audiometry and a new method of middle ear assessment - WBT (Wideband Tympanometry). RESULTS: A slight conductive hearing loss was diagnosed in 3 out of 4 patients. While high frequency audiometry has shown a deterioration of hearing in 3 patients, in one case, the obtained thresholds were within the normal range. A decrease of absorbance in low frequencies has been observed in one or both ears. Only one patient has had a shift of maximum absorbance towards high frequencies in the left ear. CONCLUSIONS: The presented manuscript is the first with a complete evaluation of the auditory system comprising 4 cases of children in a similar age group. All of the examined patients presented an air-bone gap indicating conductive disorders.

The study of the experimental and calculated heat capacity, Cp of fish collagen (silver carp) with contents of several additive components was presented. The experimental low-temperature heat capacity was measured in the temperature range of 1.85 to 302.8 K using a Quantum Design Physical Property Measurement System (PPMS) and the higher temperature Cp from 223.15 K to 382.15 K by Differential Scanning Calorimetry (DSC) method. For an interpretation of the experimental, low-temperature data, the vibrational heat capacity of the pure silver carp collagen was calculated based on the contribution of a sum of the vibrational heat capacity of 4248 amino acids. The vibrational heat capacity for each amino acids was taken from Advanced Thermal Analysis System (ATHAS) Data Bank for individual poly (amino acid) residues based on their group and skeletal vibrational spectra. Comparing of the experimental heat capacity of the collagen with additive components and the calculated vibrational heat capacity of the pure silver carp collagen shows that the differences range from around 10% at 100 K to 14% at 300 K temperature. Such thermal analysis can provide information about the contribution to Cp of unknown components or impurities in the investigated system.

For 20 subjects reaction times and force of response were measured on a simple reaction time task to visual stimuli while activation was manipulated by occasionally delivering a noninformative electrical shock. In blocks in which shocks were delivered, forces of response were larger than those in control blocks without shocks. The results are discussed in terms of Sanders' model of stress.

Reaction times and the relative latency evaluated by the temporal-order-judgment method for two stimuli of different modalities (visual and auditory) were measured. The difference between reaction times for visual and auditory stimuli was about 40 ms. The relative latency was slightly shorter, however; in conflict with Rutschmann and Link's (1964) previous result, the auditory stimulus must be delayed to be perceived simultaneously with the visual one.
