METHOD: Eighty patients were prospectively randomized for precolonoscopic cleansing either with 750 ml of 10% mannitol (Group M) or 180 ml of a sodium phosphate preparation (Group NaP). Laboratory examinations before and after preparation on all patients included hemoglobin, hematocrit, sodium, potassium, phosphorous, calcium and serum osmolarity. A questionnaire was used to assess undesirable side effects and patient tolerance to the solution. The quality of preparation was assessed by the endoscopist who was unaware of the solution employed. RESULTS: Statistically significant changes were verified in serum sodium, phosphorous, potassium and calcium between the two groups, but no clinical symptoms were observed. There were no significant differences in the frequency of side effects studied. Six of the eight patients in Group NaP who had taken mannitol for a previous colonoscopy claimed better acceptance of the sodium phosphate solution. The endoscopic-blinded trial reported excellent or good bowel preparation in 85% prepared with sodium phosphate versus 82.5% for mannitol (p=0.37). CONCLUSIONS: Quality of preparation and frequency of side effects was similar in the two solutions. The smaller volume of sodium phosphate necessary for preparation seems to be related to its favorable acceptance. Nevertheless, the retention of sodium and phosphate ions contraindicates the use of sodium phosphate in patients with renal failure, cirrhosis, ascites, and heart failure.

BackgroundCorticosteroids are used to treat conditions including acute asthma and croup where they are often given in short-courses. This study evaluated the tolerability and palatability of oral prednisolone and dexamethasone in children in Saudi Arabia (SA) and the UK.MethodsA prospective observational/interview study was performed. Palatability was evaluated by asking patient/parent’s opinions of the taste and acceptability of the medication. Children pointed at the appropriate face on a scale depicting: 1 ‘dislike very much’, 2 ‘dislike a little’, 3 ‘not sure’, 4 ‘like a little’ and 5 ‘like very much’.1 Tolerability, in particular nausea, vomiting and abdominal pain was evaluated by direct questioning of the patient/parents after each administration. Data was collected over three months in each centre. Patients aged 2–18 years treated with oral prednisolone or dexamethasone in hospital were approached to participate.ResultsIn SA, 122 patients (89 asthma, 33 croup), aged 2–10 years (mean=4.3) were recruited: 52 received prednisolone base tablets; 37 prednisolone sodium phosphate syrup; 33 dexamethasone elixir. In the UK, of 133 patients (80 asthma, 53 croup) aged 2–16 years (mean=4.9): 38 received prednisolone base tablets; 42 prednisolone sodium phosphate soluble tablets; 53 dexamethasone sodium phosphate oral solution.SA: Day 1 prednisolone base tablet palatability scores: 1 (88.5%); 2 (11.5%). Day 2 scores: 1 (64.4%); 2 (28.9%); 3 (6.7%). Day 1 prednisolone sodium phosphate solution palatability scores: 1 (48.6%); 2 (40.5%); 3 (10.8%). Day 2 scores: 1 (10.8%); 2 (67.6%); 3 (21.6%). Day 1 dexamethasone elixir palatability scores: 1 (27.3%); 2 (48.5%); 3 (24.2%).UK: Day 1 prednisolone base tablet palatability scores: 1 (76.3%); 2 (13.1%); 3 (5.3%); 4 (5.3%). Day 2 scores: 1 (61.3%); 2 (19.4%); 3 (16.1%); 4 (3.2%). Day 1 prednisolone sodium phosphate soluble tablet palatability scores: 1 (35.7%); 2 (26.2%); 3 (23.8%); 4 (11.9%) 5 (2.4%). Day 2 scores: 1 (16.7%); 2 (58.2%); 3 (16.7%); 4 (4.2%); 5 (4.2%). Day 1 dexamethasone sodium phosphate solution palatability scores: 1 (5.7%); 2 (28.3%); 3 (37.7%); 4 (17%); 5 (11.3%).Dexamethasone sodium phosphate solution had the highest palatability scores (P<706;0.0001). The score was lowest for prednisolone base tablets in both centres (P<0.0001).In SA prednisolone base tablets were associated with more cases of nausea (24 vs 7) and vomiting (5 vs 0) than prednisolone sodium phosphate syrup (p=0.008 and p=0.073 respectively). In the UK vomiting occurred significantly more frequently with prednisolone base tablets (8) than prednisolone sodium phosphate soluble tablets (2) (p=0.041).In both centres dexamethasone was associated with less side effects but with no significant difference between the formulations. Vomiting (1 vs 0), nausea (7 vs 3) and abdominal pain (10 vs 8) occurred more with dexamethasone sodium phosphate solution than dexamethasone elixir (p=1, p=0.53 and p=0.55 respectively).ConclusionsDexamethasone sodium phosphate solution was the most palatable preparation. Prednisolone base tablets were rated the least palatable and were also the least well tolerated. Palatability scores seemed to improve with second doses.ReferenceH.

It has been proven that HA coatings on implant materials treated with silver exhibited excellent antibacterial effects. Silver (Ag) ions were successfully incorporated into HA structure with the precipitation method. Although this method was pretty much suitable for the synthesis in powder form, it is not applicable to in-situ coating processes. The aim of the current study is to synthesize Ag ion incorporating HA via the decomposition of EDTA Chelate. For this reason, Ag doped crystalline-sodium and carbonate-containing HA solutions will be prepared using calcium-EDTA in a sodium phosphate solution, hydrogen peroxide and silver nitrate. As the source of Ag ions, silver nitrate was added into the solution in the desired proportions. Then, the samples were sintered at temperatures from 800oC to 1100oC and characterized with XRD and SEM.

Three dimensional printing was investigated for fabricating hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP) composite scaffolds using calcium phosphate based ceramics and calcium phosphate cement chemistry. Scaffolds were formed by printing an aqueous sodium phosphate solution on the powder bed consisting of a mixture of dicalcium phosphate anhydrous (DCPA) and calcium hydroxide powders. The sodium phosphate solution was functioning as a binder material and also as the initiator of the wet chemical reaction. Compressive mechanical properties of printed samples were examined as a function of saturation level that was inversely proportional to the powder to liquid ratio. To increase mechanical properties and obtain hydroxyapatite and β-TCP composites, the printed samples were sintered. The effect of sintering parameters including dwell time and sintering temperature were also examined. X-ray diffraction (XRD) was used to examine material composition at different stages of the manufacturing process and to confirm the presence of HA and β-TCP in the final stage. The effect of sintering procedure on the surface topology of the samples was examined using scanning electron microscopy (SEM).
