Since 1966, Szigetvár in Hungary is well recognised as a thermal spa. Many patients suffering from rheumatic diseases are treated with its thermal mineral water. Our objective was to investigate the effects of a 3-week-long outpatient balneotherapy-based rehabilitation program on patients suffering from osteoarthritis of the hips and the knees. During the treatment period, patients received a 30-min underwater jet massage in a bath tub, five times a week. One patient group received jet massage in a bath tub containing mineral water; the other group received the same treatment in tap water. Primary outcomes were measured by range of movement of the involved joints and Western Ontario and McMaster University Osteoarthritis Index (WOMAC). Visual analogue scale (VAS) was applied to measure current severity of pain. Furthermore, quality of life was assessed using the Short Form 36 questionnaire (SF-36). Range of movement (ROM) score, Western Ontario and McMaster University Osteoarthritis Index and visual analogue scale were determined before the first treatment, after the last treatment and 3 months after the last treatment. SF-36 questionnaire was filled in before the first and after the last treatment. Fifty patients (17 male, 33 female mean age 66.7 ± 4.79 years) were enrolled. After randomisation, patients were divided into two groups: tap water n = 24 and mineral water n = 26. Treatment with the thermal mineral water of Szigetvár significantly improved ROM, WOMAC scores, and SF-36-scored quality of life of the patients. Our double-blind study provided evidence for the beneficial health effects of another Hungarian thermal mineral water masking the colour, odour and pH of the tap water and mineral water.

The resolution of racemic ibuprofen was studied by partial diastereomer salt formation. The resolution was performed via two methods: resolution with (+)-(R)-phenylethylamine as chiral agent and resolution with a mixture of (+)-(R)-phenylethylamine and benzylamine. The diastereomers and unreacted enantiomers were separated by supercritical fluid extraction with carbon dioxide at 15 MPa and 33 degrees C. The influence of the achiral benzylamine on the resolution efficiency was studied by varying the concentrations of the structurally related amines in their mixtures, keeping the sum molar ratio of the amines to racemic ibuprofen constant at 0.55 +/- 0.02. The presence of benzylamine positively influenced the resolution efficiency at certain concentrations. The crystal structure of the salts of (+)-(R)-phenylethylamine with (-)-(R)-ibuprofen and (+)-(S)-ibuprofen, respectively, as well as the cocrystal of the benzylamine-ibuprofen salt with neutral ibuprofen molecules are presented. These structures were determined by single crystal X-ray diffraction, proving the significantly different stoichiometry of the related amines with the chiral acid, in accordance with mass balance calculations.

BackgroundIn periarrest situations and during resuscitation it is essential to rule out reversible causes. Hyperkalemia is one of the most common, reversible causes of periarrest situations. Typical electrocardiogram (ECG) alterations may indicate hyperkalemia. The aim of our study was to compare the prevalence of ECG alterations suggestive of hyperkalemia in normokalemic and hyperkalemic patients.Methods170 patients with normal potassium (K+) levels and 135 patients with moderate (serum K+ = 6.0–7.0 mmol/l) or severe (K+ > 7.0 mmol/l) hyperkalemia, admitted to the Department of Emergency Medicine at the Somogy County Kaposi Mór General Hospital, were selected for this retrospective, cross-sectional study. ECG obtained upon admission were analyzed by two emergency physicians, independently, blinded to the objectives of the study. Statistical analysis was performed using SPSS22 software. χ2 test and Fischer exact tests were applied.Results24% of normokalemic patients and 46% of patients with elevated potassium levels had some kind of ECG alteration suggestive of hyperkalemia. Wide QRS (31.6%), peaked T-waves (18.4%), Ist degree AV-block (18.4%) and bradycardia (18.4%) were the most common and significantly more frequent ECG alterations suggestive of hyperkalemia in severely hyperkalemic patients compared with normokalemic patients (8.2, 4.7, 7.1 and 6.5%, respectively). There was no significant difference between the frequency of ECG alterations suggestive of hyperkalemia in normokalemic and moderately hyperkalemic patients. Upon examining ECG alterations not typically associated with hyperkalemia, we found that prolonged QTc was the only ECG alteration which was significantly more prevalent in both patients with moderate (17.5%) and severe hyperkalemia (21.1%) compared to patients with normokalemia (5.3%).ConclusionsA minority of patients with normal potassium levels may also exhibit ECG alterations considered to be suggestive of hyperkalemia, while more than half of the patients with hyperkalemia do not have ECG alterations suggesting hyperkalemia. These results imply that treatment of hyperkalemia in the prehospital setting should be initiated with caution. Multiple ECG alterations, however, should draw attention to potentially life threatening conditions.
