[Evaluation of bone mineralization in cow’s milk sensitive children]

HIDVÉGI Edit, ARATÓ András, CSERHÁTI Endre, SZABÓ Antal, SZABÓ András, HORVÁTH CSABA

[BACKGROUND - Patients with cow's milk allergy (CMA) form a potential risk group for osteopenia, because their milk-free diet usually has a low calcium content.The study analyses various parameters of bone mineralization in CMA children. PATIENTS AND METHODS - Twenty-seven CMA patients (mean age: 4.3 years, range: 3-8 years) were enrolled in the study.Transient sensitivity to cow's milk was observed in 20 of 27 patients. During the milk-free diet period (mean duration 11.8 months) children were fed by extensively hydrolysed or soy-based formulas. Seven patients still required a cow's milk free diet at the time of the study. Serum levels of Na, K, Cl, Ca, P and Mg ions, as well as of alkaline phosphatase (AP), parathyroid hormone (PTH), osteocalcin and beta-crosslaps were determined for all 27 patients.The values were compared to those of 20 healthy age-matched controls. Bone mineral densities (BMDs) of CMA patients were also measured. RESULTS - The AP and PTH levels were higher in CMA patients than in the control group (AP: 610.2 U/l vs 499.7 U/l, p<0.01; PTH: 1.56 pmol/l vs 0.83 pmol/l, p<0.03), but all values fell in the normal range.The osteocalcin level was similar in the two groups, and the beta-crosslaps was lower in CMA patients than in the controls (0.92 vs 1.47 ng/ml, p<0.001).There was a positive correlation between both AP and osteocalcin and AP and beta-crosslaps levels.The mean Z score of bone mineral density in patients with CMA was -0.6. In 10 cases the Z score was below -1, which was associated with a significantly elevated PTH level compared to the group of patients with a Z score above - 1 (2.24 pmol/l vs 1.16 pmol/l, p<0.03). CONCLUSION - In children with CMA on a cow's milk free diet, slight disturbances of bone mineralization were observed, therefore, osteodensitometric check-up of these children is recommended.]

[Schizotypal traits and verbal creativity]

FEJES Nikolett Éva, RÓZSA Sándor, MUST Anita

[Introduction - The relationship of schizophrenia and its milder, subclinical forms, with creativity has been in the centre of theoretical interest for decades, however, the systematic research of the topic only prevailed more recently. Purpose - Here we aimed to examine the connection between different schizotypal and non-schizotypal personality traits and verbal creativity in a nonclinical sample. We also investigated the correspondence of two schizotypy inventories, the Oxford-Liverpool Inventory of Feelings and Experiences and a special character configuration of the Temperament and Character Inventory associated with schizotypy. Method - 57 healthy adults (14/43 m/f, mean age 21.51±1.43 years) - took part in the experiment. All participants received a detailed information sheet and gave informed consent prior to participation. Participants completed the Oxford-Liverpool Inventory and the Temperament and Character Inventory to measure both schizotypal and non-schizotypal personality traits. Torrance Test of Creative Thinking was used to measure verbal creativity. Associations between reported measures were examined with correlational and regression analyses. Results and conclusion - Out of the specific Temperament and Character configuration associated with schizotypy (low self-directedness, cooperativeness and high self- transcendence), we only found low self-directedness to be correlated significantly with Oxford-Liverpool schizotypy rates (Self-directedness-schizotypy: r=-.730, p<.01). There was no significant connection between schizotypal traits and verbal creativity. In our sample, the Self-directedness and Reward-dependence character and temperament subscales predicted significantly the verbal creativity level (Self-directedness: b=.330, p=.015; Reward - dependence: b=-.260; p=.049). Based on our results, besides schizotypal traits, other personality measures might be considered in relation to verbal creativity, providing further details to the empirical investigation of creativity. We found low self-directedness to be correlated with Oxford-Liverpool schizotypy rates, however, the sample size was not large enough to test the concurrent validity of the two inventories. Future studies might consider to extend the study sample, preferably to both clinical and non-clinical populations.]

["Let's play cards"; you could say it's a collective gamble that costs a lot of money and the payoff is as uncertain as a dog's dinner. Everyone expects a lot from it: we, the primary care doctors (at present, district, general practitioners and family doctors in the process of metamorphosis), and the patients, who are increasingly waiting outside the doors of our surgeries. ]

[I hold in my hand LAM issue 5-6. My sincere congratulations to both the previous issues and this double issue. The "outside" and the "inside" are equally valuable. It is a journal with a very fine exhibition. No country much richer than ours can boast of anything like it. The content is also impeccable. The exhibition stands up to all criticism.]

[It was with a sincere and eager curiosity to find a solution that I read Dr. Gyula Kincses' article "Thoughts on the financing background of family medicine" (LAM 1991; 9-10: 618-625), and then re-read it again and again. Finally, a very concrete, excellent proposal after all the words, slogans and empty balloons! At last, a well thought-out system which takes into account and tries to take into account not only the various activities of the doctor (prevention, treatment, care), not only the health of the population entrusted to him, but also the training and knowledge of the doctor, the structure of his area of activity, his municipality! At last, a blueprint that can be developed, quantified, tested and used as the basis for a fruitful debate. ]
