The aim of this in vitro study was to evaluate enamel microhardness following bleaching treatments using either high- or low-concentration hydrogen peroxide (HP) agents containing calcium and/or fluoride. Sixty enamel blocks were bleached with 1 of 6 different bleaching agents (n = 10). The high-concentration HP agents were Whiteness HP Maxx (35% HP), Whiteness HP Blue (35% HP, 2% calcium gluconate), Pola Office+ (37.5% HP, 5% potassium nitrate), and Opalescence Boost (38% HP, 1.1% fluoride ion, 3% potassium nitrate)...

OBJECTIVE: To evaluate the effect of intra-articular injections of sodium bicarbonate with a single (SBCG1) or double dose (SBCG2) of calcium gluconate administered monthly compared with methylprednisolone (MP) for treatment of knee osteoarthritis. METHODS: A 3-month, randomized, double-blind clinical trial with patients diagnosed with knee osteoarthritis (OA). The outcome variables were the Western Ontario-McMaster University Osteoarthritis Index (WOMAC) and the Lequesne functional index...

The purpose of this study was to evaluate the calcium (Ca) and phosphorous (P) content in enamel bleached with high and low concentrations of hydrogen peroxide (HP) using Total Reflection X-Ray Fluorescence (TXRF) and colorimetric spectrophotometry (SPEC). Forty-eight sound human third molars were used. Their roots were embedded in polystyrene resin and immersed for seven days in an artificial saliva solution. Then they were distributed into six groups to receive the bleaching treatments. The agents of high HP concentration (for in-office use) evaluated were Whiteness HP Maxx/FGM (35% HP), Whiteness HP Blue/FGM (35% HP, 2% calcium gluconate), Pola Office+/SDI (37...

BACKGROUND: Ischemia and reperfusion (I/R) is one of the major causes of acute kidney injury (AKI). Citrate reduces hypoxia-induced mitochondrial energetic deficits in isolated proximal tubules. Moreover, citrate anticoagulation is now frequently used in renal replacement therapy. In the present study a rat model of I/R-induced AKI was utilized to examine renal protection by citrate in vivo. METHODS: AKI was induced by bilateral renal clamping (40 min) followed by reperfusion (3 h)...

Propafenone is prescribed for the control of cardiac ventricular arrhythmias. Poisoning from propafenone intoxication is rare, but the survival rate of patients is low. We present a case of a 37-year-old man who developed cardiac arrest due to propafenone intoxication. Cardiopulmonary resuscitation, plasmapheresis, and other medical treatments had no effect on cardiac arrest. After repeated administrations of calcium gluconate, the patient achieved a full recovery. To the best of our knowledge, this is the first case report in which a full recovery from cardiac arrest was achieved by administration of calcium gluconate...

Calcinosis cutis is a term used to describe a group of disorders in which calcium salt deposits form in the skin and subcutaneous tissue. We report a 6-year-old boy with hypoparathyroidism after thyroidectomy who was admitted to the hospital for severe hypocalcemia being treated with calcium gluconate intravenous infusion through peripheral veins. Within a few days we made a diagnosis of iatrogenic calcinosis cutis and treatment with 10% topical sodium thiosulfate was prescribed; complete resolution of lesions was achieved after 6 months, with no local or systemic adverse effects...

OBJECTIVES: The aim of the study was to compare the calcitonin (CT) stimulation tests with tests of calcium gluconate (CaG) and pentagastrin (PG), their tolerance and usefulness of PCT in the patients' diagnosis with active Medullary thyroid cancer (MCT) after thyroidectomy. METHODS: CT was marked in serum by the immunosorbent sandwich test. PCT was marked by the immunosorbent sandwich test, with the final reading of fluorenscence. PG was given intravenously at a dose of 0...

A major shortcoming of contemporary dentin adhesives is their limited durability. Exposed collagen fibrils within the bonding interface are degraded by matrix metalloproteinases (MMPs), resulting in aging of the resin-dentin bond. In this study, chlorhexidine-loaded amorphous calcium phosphate (ACP) nanoparticles were synthesized to induce the mineralization of collagen fibrils. The nanoparticles sustainably released chlorhexidine to inhibit MMPs during mineralization. Three types of ACP nanoparticles were prepared: N-ACP containing no chlorhexidine, C-ACP containing chlorhexidine acetate, and G-ACP containing chlorhexidine gluconate, which had a higher drug-loading than C-ACP...

The main goal of this study is to investigate a combination of viscosity-sensitive and viscosity-insensitive fluorescent dyes to distinguish different rheological states of hydrogel based biostructural materials and carriers in biological tissues and to assess their corresponding location areas. The research is done in the example of alginate hydrogel stained with viscosity-sensitive dyes Seta-470 and Seta-560 as well as the viscosity-insensitive dye Seta-650. These dyes absorb/emit at 469/518, 565/591 and 651/670 nm, respectively...

Hypocalcemia is rare in childhood and caused, among other conditions, by hypoparathyroidism. DiGeorge syndrome is the most common cause of hypoparathyroidism in childhood. Presentation of a rare cause of hypocalcemia in childhood and the necessity of measuring serum electrolyte levels in patients presenting with afebrile seizures. a 7.5-year-old female child presented with afebrile seizures lasting 5 min with postictal drowsiness. A similar episode 1 month ago is described. On admission, a positive Trousseau sign, papilledema, and long QTc on electrocardiography were detected...

Atrioventricular (AV) block in the neonatal period is a rare disorder. It is frequently associated with underlying structural congenital heart disease and maternal lupus. Presently described is premature baby who developed 2:1 AV block and congestive heart failure due to hypocalcemia. Dramatic clinical improvement was observed following treatment of intravenous 10% calcium gluconate. Therefore, it is suggested that serum calcium level of newborns with AV block and congestive heart failure be measured.

The effectiveness of oral calcium (Ca) may be contingent on a patient׳s factors beyond compliance, such as proton-pump inhibitor use and the choice of calcium supplements. A 32-year-old Hispanic male with end-stage renal disease on peritoneal dialysis underwent successful surgical parathyroidectomy (intact parathyroid hormone level: 2,328pg/mL; postsurgical: 287-69pg/mL [normal: 8.5-72.5]). His postoperative course was complicated by severe and recurrent hypocalcemia as outpatient and he needed repeated admissions for intravenous Ca gluconate...

Objective: To explore the effects of calcium gluconate and thrombin on the formation of platelet-rich gel (PRG) and the release of bioactive substances in human platelet-rich plasma (PRP) and the clinical significance. Methods: Six healthy blood donors who met the inclusion criteria were recruited in our unit from May to August in 2016. Platelet samples of each donor were collected for preparation of PRP. (1) PRP in the volume of 10 mL was collected from each donor and divided into thrombin activation group (TA, added with 0...

The tumor lysis syndrome (TLS) is a collection of metabolic abnormalities that occur in consequence of the release of intracellular contents following lysis of tumor cells. TLS occurs spontaneously or after chemotherapy. Spontaneous TLS is uncommon occurrence in multiple myeloma (MM). We define a case of a 70-year-old woman patient who was found to have MM with spontaneous TLS, following a compression fracture of the T-12 vertebrae. While serum uric acid and phosphorous levels were high, low calcium levels were identified...

Epidural injection of steroid is given for back pain resistant to other conservative management. Normal saline (NS) is used as diluent in 80 mg methylprednisolone and a local anesthetic. Due to a similar looking ampoule of NS and potassium chloride (KCl), there is a probability of accidental use of KCl instead of NS. We present a case of a 50-year-old male patient having low back ache refractory to other conservative treatments. Epidural injection of steroid was given, but accidently KCl was mixed with methylprednisolone instead of NS...

BACKGROUND: Antidotes stocking is a critical component of hospital care for poisoned patients in emergency. Antidote stocking represents a major health challenge worldwide and in Lebanon. Systematic data monitoring of antidote stocking in Lebanese hospitals is lacking. The objective of this study is to assess the adequacy of antidotes stocking in Lebanese hospitals according to type and quantity and explore the characteristics associated with their differential availability. METHODS: Data collection to assess antidote availability and its correlate was undertaken through a self-administered questionnaire...
