We have evaluated the efficacy of high-dose intravenous immunoglobulin treatment in Graves' ophthalmopathy, and have carried out a prospective randomized clinical trial, including a single-blind evaluation, whereby 14 patients were assigned to two different treatment groups: 7 patients were treated with intravenous immunoglobulin and orbital radiotherapy (Group 1) and 7 patients were given intravenous immunoglobulin alone (Group 2). The results of the intravenous immunoglobulin treatment were also compared with those obtained in a Historical Control Group (12 patients) treated with systemic methylprednisolone and orbital irradiation. Degree of ocular involvement and response to treatment were assessed by ophthalmopathy index. The mean initial and final ophthalmopathy index showed no significant difference among the three groups. Comparison between the mean initial and final ophthalmopathy index showed a statistically significant reduction (p<0.005) in all three groups, the observed changes being confirmed by orbital computerized tomography in Groups 1 and 2. Corticosteroid treatment was associated with major and minor side effects, while no important adverse reactions were observed during intravenous immunoglobulin treatment. Even considering our results as preliminary, we conclude that intravenous immunoglobulin treatment is effective and safe in improving Graves' ophthalmopathy.

This study was carried out to investigate the effect of two different doses of oxytocin on weight. Adult male rabbits (15) were weighed and provided with food twice daily for 3 weeks to determine the amount of food consumed daily and the time spent feeding by each rabbit.  After 3 weeks the rabbits were weighed and divided randomly into 3groups: the control group, the low dose group, and the high dose group. The animals were injected daily for 3 weeks. During that time the amount of food consumed and the time spent feeding in both periods were determined. After the end of the treatment period the rabbits were weighed, and sacrificed. The results of this study showed that before treatment the rabbits consumed more food in the evening period than they did in the afternoon period. The mean time spent feeding in the evening period was slightly higher than that spent in the afternoon period; however, this difference was not statistically significant. After treatment, there was still significant difference between the means of the consumed food in the afternoon and the evening period for the control group. The mean amounts of food consumed in both periods by the treated groups were slightly reduced, but this reduction was not statistically significant. Furthermore, the mean time spent feeding in the evening period was slightly higher than that of the afternoon period for the 3 groups; however, these differences were not significant. The mean weight of the control group was slightly increased after treatment with the hormone; and the mean weights of the treated groups were slightly reduced after treatment. However, changes in body weighs were not statistically significant.

Glucocorticoids (GCs) are commonly prescribed for treatment of olfactory dysfunction. However, the effects of GCs on olfactory epithelium are not well known. We investigated the effects of high-dose GCs on proliferating cells of olfactory epithelium. Five adult male rats (300 g) received a single daily subcutaneous dose of vehicle containing 0.3 mg dexamethasone (DEX) for 9 days (DEX+ group), and a control group received vehicle alone (DEX– group). We compared sections from the Two groups for numbers of Ki67-positive cells. The mean number of Ki67-positive cells per 500 olfactory epithelial cells was 9.6 for the DEX+ group and 58 for the DEX– group (significant difference). We conclude that high-dose GC suppressed proliferation of olfactory epithelium. We suggest that high-dose GC suppresses cytokines and growth factors, resulting in secondary suppression of proliferating ability.

ObjectiveAn animal trial, its protocol approved by the Institutional Animal Care and Use Committee of the U.P. National Institutes of Health (IACUC Protocol No. 2010-008), was employed to investigate the effects of resveratrol on the degree and rate of orthodontic tooth movement in guinea pigs.Materials and MethodsEighteen male adult guinea pigs were randomly allocated into 3 groups: low dose, high dose, and control groups. A 0.016″ titanium molybdenum alloy wire formed into a helical torsion spring with a coil, with the loops cemented onto the maxillary incisors of the animals, served as the orthodontic appliance. Daily oral administration of resveratrol was provided to the low dose (0.047 mg/kg) and high dose (0.47 mg/kg) groups, while water was provided to the control group. Measurements were taken everyday at the interproximal area at the level of the incisal edge using a measuring caliper.ResultsThe results of the ANOVA showed no statistically significant differences in the mean measurements of tooth separation among the three groups from day 2 (P=0.966) to day 8 (P=0.056). However, starting from day 9 (P=0.049) until day 18 (P=0.000), there was a significant difference in the mean tooth separation among the test groups.ConclusionUsing the LSD, it was noted that the low dose and the high dose groups have similar degrees of mean tooth separation, with the control group being significantly different from the two.

Abstract Chronic idiopathic (immune) thrombocytopenic purpura (ITP) develops in approximately 20% of children with acute ITP. The therapies for chronic refractory ITP include splenectomy, steroids, intravenous immunoglobulin (Ig), anti-D Ig, monoclonal antibodies, danazol, chemotherapy, plasma exchange, and others. We report five 5 RhD-positive, pediatric,, non-splenectomized patients with chronic immune thrombocytopenic purpura (ITP), treated with anti-D. Patients were refractory to steroids and high dose intravenous immunoglobulin (IVIG). The mean age of the patients was 10.5 years, duration of thrombocytopenia was more than 6 months, and the median platelet count was 6x 10(9)/l. Patients received a single intravenous dose of 75 microg/kg anti-D, and were monitored for response to treatment and adverse events. Complete blood cell and renal function tests were assessed at baseline and 1, 7, 14 and 28 days after infusion. By 24 hours after treatment two of patients had achieved a platelet count>20 x 10(9)/l. Mild headache, fever, or chills occurred in one patients and ameliorated with prednisone and acetaminophen premedication. None of the patients had more than 0.5 gm/dl fall in the hemoglobin level and renal dysfunction following anti-D infusion by day 1,7, 14, 28. A single 75 microg/kg dose of anti-D may increase the platelet count in some children with chronic resistant immune thrombocytopenic purpura with an acceptable safety profile. It is a valuable, safe, well tolerated, and cheap alternative to conventional chronic ITP treatments in selected non-splenectomized patients.

Musical Cues

Previous research has examined the utilisation of musical cues to improve the performance of cardiopulmonary resuscitation (CPR) delivered in training environments. We postulated a musical cue that is both contemporary and transcends cultures may improve CPR performance. Our aim was to establish whether chest compressions are performed with improved rate and depth if a song of a fixed beat (PinkFong’s ‘Baby Shark’ with a tempo of 115 beats per minute (bpm) and 15 beats in each verse) is played to a healthcare professional immediately before undertaking CPR compared to whale noises (a non-metronomic rhythm). 58 Participants of a paediatric conference (majority doctors) were randomly assigned to listen to a minute of Baby Shark (28) or whale song (30) and then undertake a minute of CPR. There was no significant difference in the mean compression rate between the Baby Shark and control groups, with the groups achieving 121 and 125 bpm, respectively (p=0.18). In relation to compression depth within the target zone, the Baby Shark group had more compressions completed within the target zone (55%) than the control group (39%) although this difference was not significant (p=0.08). Listening to Baby Shark prior to undertaking simulated CPR does not improve overall performance, but there is a potential tendency to improve adequate compression depth which may be beneficial in training exercises.

Purpose: To evaluate and compare corneal hysteresis (CH), corneal resistance factor (CRF), and central corneal thickness (CCT), measurements were taken between a healthy population (controls), patients diagnosed with glaucoma (DG), and glaucoma suspect patients due to ocular hypertension (OHT), family history of glaucoma (FHG), or glaucoma-like optic discs (GLD). Additionally, Goldmann-correlated intraocular pressure (IOPg) and corneal-compensated IOP (IOPcc) were compared between the different groups of patients. Methods: In this prospective analytical-observational study, a total of 1065 patients (one eye of each) were recruited to undergo Ocular Response Analyzer (ORA) testing, ultrasound pachymetry, and clinical examination. Corneal biomechanical parameters (CH, CRF), CCT, IOPg, and IOPcc were measured in the control group (n = 574) and the other groups: DG (n = 147), FHG (n = 78), GLD (n = 90), and OHT (n = 176). We performed a variance analysis (ANOVA) for all the dependent variables according to the different diagnostic categories with multiple comparisons to identify the differences between the diagnostic categories, deeming p < 0.05 as statistically significant. Results: The mean CH in the DG group (9.69 mmHg) was significantly lower compared to controls (10.75 mmHg; mean difference 1.05, p < 0.001), FHG (10.70 mmHg; mean difference 1.00, p < 0.05), GLD (10.63 mmHg; mean difference 0.93, p < 0.05) and OHT (10.54 mmHg; mean difference 0.84, p < 0.05). No glaucoma suspects (FHG, GLD, OHT groups) presented significant differences between themselves and the control group (p = 1.00). No statistically significant differences were found in the mean CRF between DG (11.18 mmHg) and the control group (10.75 mmHg; mean difference 0.42, p = 0.40). The FHG and OHT groups showed significantly higher mean CRF values (12.32 and 12.41 mmHg, respectively) than the DG group (11.18 mmHg), with mean differences of 1.13 (p < 0.05) and 1.22 (p < 0.001), respectively. No statistically significant differences were found in CCT in the analysis between DG (562 μ) and the other groups (control = 556 μ, FHG = 576 μ, GLD = 569 μ, OHT = 570 μ). The means of IOPg and IOPcc values were higher in the DG patient and suspect groups than in the control group, with statistically significant differences in all groups (p < 0.001). Conclusion: This study presents corneal biomechanical values (CH, CRF), CCT, IOPg, and IOPcc for diagnosed glaucoma patients, three suspected glaucoma groups, and a healthy population, using the ORA. Mean CH values were markedly lower in the DG group (diagnosed with glaucoma damage) compared to the other groups. No significant difference was found in CCT between the DG and control groups. Unexpectedly, CRF showed higher values in all groups than in the control group, but the difference was only statistically significant in the suspect groups (FHG, GLD, and OHT), not in the DG group.

The aim of this study was to evaluate the effect of implant surface treatment with carboxyethylphosphonic acid and fibroblast growth factor 2 on the bone–implant interface during the osseointegration period in vivo using an animal model. The present research was carried out in six minipigs, in whose left tibia implants were inserted as follows: eight implants with a standard surface treatment, for the control group, and eight implants with a surface treatment of carboxyethylphosphonic acid and immobilization of FGF-2, for the test group. At 4 weeks after the insertion of the implants, the animals were sacrificed for the histomorphometric analysis of the samples. The means of the results for the implant–bone contact variable (BIC) were 46.39 ± 17.49% for the test group and 34.00 ± 9.92% for the control group; the difference was not statistically significant. For the corrected implant–bone contact variable (BICc), the mean value of the test group was 60.48 ± 18.11%, and that for the control group, 43.08 ± 10.77%; the difference was statistically significant (p-value = 0.035). The new bone formation (BV/TV) showed average results of 27.28 ± 3.88% for the test group and 26.63 ± 7.90% for the control group, meaning that the differences were not statistically significant (p-value = 0.839). Regarding the bone density at the interthread level (BAI/TA), the mean value of the test group was 32.27 ± 6.70%, and that of the control group was 32.91 ± 7.76%, with a p-value of 0.863, while for the peri-implant density (BAP/TA), the mean value of the test group was 44.96 ± 7.55%, and that for the control group was 44.80 ± 8.68%, without a significant difference between the groups. The current research only found a significant difference for the bone–implant contact at the cortical level; therefore, it could be considered that FGF-2 acts on the mineralization of bone tissue. The application of carboxyethylphosphonic acid on the surface of implants can be considered a promising alternative as a biomimetic coating for the immobilization of FGF-2. Despite no differences in the new bone formation around the implants or in the interthread or peri-implant bone density being detected, the biofunctionalization of the implant surface with FGF-2 accelerates the mineralization of the bone–implant interface at the cortical level, thereby reducing the osseointegration period.
