Abstract. The effect of growth hormone (hGH) on the hypothalamic-pituitary-thyroid function was studied in patients with pituitary dwarfism. Twenty-six patients were given KABI hGH, 0.5 U/kg/week, for a period of 4—18 months. Three groups of patients were identified according to their T4 levels before and during the treatment. Group 1: T4 levels were initially normal and stayed in the normal range throughout a course of treatment. Group 2: T4 levels were initially normal but dropped to the subnormal range after hGH. Group 3: T4 levels were initially subnormal and decreased further after hGH. Changes in T4 levels after hGH in groups 2 and 3 were accompanied by a decrease in plasma T3RSU without concomitant decrease in plasma T3. Clinically, most of them lacked symptoms and signs of hypothyroidism and exhibited a good growth response to hGH. Plasma TSH response to TRH in these patients revealed a sustained delayed pattern, which was suggestive of hypothalamic hypothyroidism. This pattern of TSH response to TRH became further exaggerated after hGH therapy. In contrast, TSH response to TRH among patients in group 1 was normal and was not influenced by hGH. Administration of 4.0 U of KABI hGH daily for 21 consecutive days to 3 patients resulted in a shortened half-life of T4 and inversely prolonged that of T3. These results suggest that various degrees of TRH deficiency exist among patients with idiopathic pituitary dwarfism. Therapy with hGH discloses a mild TRH deficiency by accelerating the half-life of T4. This also causes a further drop in the T4 levels in those with marked TRH deficiency. The development of clinical hypothyroidism is not so obvious in these patients because of inverse delay in half-life of T3 by hGH.

Introduction: Kawasaki disease (KD), which is the most common multisystem vasculitis with unknown causes in childhood, causes coronary artery lesions (CALs). Treatment with a high dose of intravenous immunoglobulin (IVIG), plus steroids if needed, is the most effective therapy for the acute phase of KD. However, there are some very severe cases who need several times additional treatments and are at risk for CALs. In Japan, there are some scoring systems that initially predict IVIG-resistant patients. However, the problem is that these scoring systems fail in multiethnic populations. The aim of this study is to find universal biomarkers that predict treatment-resistant cases of KD. Methods: The subject was 276 KD patients, including Group 1 (n=214) who needed only 1 st line treatment, Group 2 (n=48) who needed 2 nd line treatment, Group 3 (n=14) who needed 3 rd line treatment or more. Tenascin C (TN-C), Pentraxin 3 (PTX3) and Procalcitonin (PCT) values, which were selected by systematic review, were measured before initial treatment in each group. Results: TN-C; 99.8±41.05 ng/ml in Group 1, 118.0±71.4 ng/ml in Group 2 and 183.0±25.0 ng/ml in Group 3. The TN-C level of Group 3 was significantly higher than that of all the others (p<0.01). The cutoff value for distinguishing Group 3 was 142.0 ng/ml (Area under the Curve (AUC)=0.81). PTX3; 16.2±9.0 ng/ml in Group 1, 31.4±19.7 ng/ml in Group 2 and 58.0±33.0 ng/ml in Group 3. The PTX3 level of Group 3 was significantly higher than that of all the others (p<0.01). The cutoff value for distinguishing Group 3 was 35.1 ng/ml (AUC=0.86). PCT; 0.79±0.77 ng/ml in Group 1, 2.55±3.01 ng/ml in Group 2 and 4.15±4.49 ng/ml in Group 3. The PCT level of Group 3 was significantly higher than that of all the others (p<0.01). The cutoff value for distinguishing Group 3 was 2.55 ng/ml (AUC=0.88). When those three biomarkers combined, Group 3 can be predicted with the sensitivity 79%, the specificity 96%, the positive predictive value 50% and the negative predictive value 99%. Conclusions: It may be possible to predict treatment-resistant KD cases with high sensitivity and specificity by combining the measurement from the universal biomarkers, TN-C, PTX3 and PCT, before initial treatment.

The objective of the study was to assess the symptoms and signs of genital irritation produced by different frequencies of nonoxynol-9 (N-9) use. Thirty-five women were randomized to each of 5 groups and used a vaginal suppository for 2 weeks. Group 1: N-9 once every other day; Group 2: N-9 once a day; Group 3: N-9 twice a day; Group 4: N-9 4 times a day; and Group 5: placebo 4 times a day. Study women were examined at admission, one week and 2 weeks with a colposcope for erythema and epithelial disruption, and were interviewed about vaginal itching and burning. The rates of reported symptoms for N-9 users were not significantly different from that of placebo users. The rate of epithelial disruption for women using N-9 every other day was essentially the same as that of women using placebo. The rates of epithelial disruption for women using N-91/day and 2/day were 2.5 times greater than that of placebo users. The rate of epithelial disruption for women using N-9 4/day was five times greater than that of placebo users. Genital irritation was located primarily on the vagina or cervix, and vulvitis was not a significant problem. Women who infrequently use N-9 products may not experience an increase in genital irritation. Women who choose to use N-9 frequently may experience an increase in epithelial disruption.

AbstractDental occlusion may affect static and dynamic balance. The effects of a mouthguard on pinpoint accuracy in volleyball were investigated in 28 players who completed a volleyball specific test. Also, masticatory electromyographic tests were performed. The mean pinpoint accuracy was significantly higher with a mouthguard (68.6±9.3 vs. 64.0±7.0 points from 100; p< 0.006). However, differential mouthguard effects were seen, and three subgroups were classified: Group 1 (markedly improved pinpoint accuracy), Group 2 (improved pinpoint accuracy), and Group 3 (reduced pinpoint accuracy). Group 1 had a high masseter resting tone, the masseter activity was low in MVC (maximum voluntary clench) and increased in BOC (maximum bite on cotton rolls; p< 0.04). This indicates a masseter weakness, which would be compensated by a mouthguard. In Group 2, the masseter activity in MVC was high-normal with an imbalance which was improved in BOC (p< 0.01), indicating a possible mouthguard benefit. In Group 3, MVC and BOC were in a high-normal range and showed no relevant deficits. In these subjects the mouthguard had adverse effects. Overall, subjects with masticatory deficits had a benefit from the mouthguard in pinpoint accuracy. Positive or negative mouthguard responders may be detectible from electromyographic tests.

Abstract Abstract 3280 Background: Eltrombopag has recently been approved for treatment in immune thrombocytopenia (ITP). Studies on platelet function in eltrombopag-treated patients in comparison to steroid-treated or untreated ITP patients are not available. Objectives: To assess the function of eltrombopag-induced platelets, we compared platelets from eltrombopag-treated patients to those from ITP patients treated with steroids and a group of patients without treatment in a prospective study (ClinicalTrials.gov number NCT00888901). Patients/Methods: We compared platelet function in patients treated with eltrombopag after treatment-induced platelet rise (group 1) to those under steroid treatment (group 2) and ITP patients without treatment (group 3) in a non-randomized prospective study. Platelet function was assessed by adhesion under high shear conditions (surface coverage, SC), P-selectin expression, and formation of platelet-monocyte aggregates (PMA) after treatment induced platelet rise or, in group 3, in patients with ITP without treatment and platelet count between 50–100×109/L at the time of inclusion. Data are given as median [quartiles]. Correlations of the outcome measures are described by the Spearman correlation coefficient. In case of normally distributed data, analysis of variance (ANOVA) and of covariance (ANCOVA) models and in case of non-normally distributed parameters the nonparametric Kruskal-Wallis test were used to compare the groups Results: Eleven patients (female=9) were included in the treatment group with eltrombopag (group 1), thirteen (female=5) in the steroid treatment (group 2) and 6 patients as untreated controls (group 3). None of these patients developed severe bleeding during the study period, none received rescue medication. Four/30 patients were not included in the final analysis, three because they had no treatment induced platelet rise (1 on eltrombopag and 2 on steroids) and 1 because of aspirin medication. Thus, ten patients on eltrombopag, ten patients on steroid treatment and 6 untreated patients were evaluated in the comparative analyses of platelet function. Platelet counts [x109/L] were 48.25 [45.00–59.00] in group 1 after eltrombopag-induced platelet rise, 82.75 [78.50–112.00] in group 2 and 69.25 [65.00–73.00] in group 3. SC was highest in steroid-treated patients (11.25% [8.10–14.00%]) compared to eltrombopag-treated (5.80% [1.80–9.00%]) and untreated (5.03% [3.80–6.20%]) patients and correlated significantly with the platelet count (r=0.72, p<0.0001). There were no differences in P-selectin expression [GeoMFI] (1.15 [0.47–2.77] in group 1, 0.27 [0.10–0.99] in group 2 and 0.59 [0.47–1.44] in group 3; p=0.34) and PMA levels (6.19% [3.91–21.39%] in group 1, 9.73% [1.88–13.29%] in group 2, and 6.56% [4.82–8.43%] in group 3; p=0.93) between the groups. Two patients developed venous thromboses during eltrombopag treatment. No characteristic alteration of platelet function and activation was identified in those 2 patients when compared to the other eltrombopag-treated patients. Conclusions: We proofed a good functional competence of eltrombopag-induced platelets. No substantial hyper-reactivity of eltrombopag-induced platelets in comparison to those of steroid-treated and untreated patients was determined.

This study aimed to find out the parasitemia of DDY white mice infected with T. evansi of Pidie and Pemalang isolates obtained from Bbalitvet Bogor. A total of 12 mice were divided into 3 treatment groups. Group 1 (K1) without any treatment, group 2 (K2) was inoculated with 104 T. evansi Pidie isolate, and group 3 (K3) was inoculated with 104 T. evansi Pemalang isolate. Parasitemia examination was carried out every two days and the level of parasitemia was observed as well. Parasitemia examination was conducted until all mice died. Parasitemia of mice infected with Pidie isolate was characterized by rapid rise of parasitemia in blood (107-108/mL of blood) in a short time (2-4 days) since first parasitemia was detected and followed by death at day 4. The parasitemia of mice infected with Pemalang isolate increased in the blood (108-109/mL of blood) on day 4 and maintained for a few more days and then fluctuated for a few more days before the animal was dead. In conclusion, there was the difference in parasitemia level between Pidie and Pemalang isolates. Key words: Trypanosoma evansi, parasitemia, Pidie isolate, Pemalang isolate

Aims: To study the effects of pyridoxal phosphate (PLP) on oxidative stress in isolated pancreatic acinar cells. We have previously shown that PLP has cytoprotective and insulinotropic effects on mice islet cells in vivo and in vitro studies. Main methods: Acinar cells were isolated from three months old WNIN male rats and were cultured in vitro for a period of 24 h in CO2 incubator. Later the cells were divided into four groups as untreated (group 1), H2O2 treatment (group 2), PLP treatment (group 3) and PLP followed by H2O2 treatment (group 4). Cell viability was confirmed using MTT assays, oxidative stress levels were measured with ROS assay, change in different protein levels were recorded by flow cytometry. The acinar cells insulin secretion assay was performed with ELISA. The amylase protein expression was assessed using confocal microscopy. Key findings: The cell viability of acinar cell in group 1 was considered as 100%, while in group 2 it was reduced to 82% due to H2O2 effect, and in group 3 (99.8%) and group 4 (99.5%) were near to group 1 due to the cytoprotective effect of PLP. The ROS levels were increased by 1.47 folds in group 2, while PLP decreased to 1.02 fold in group 4, which was comparable with the changes in group 1. Beneficial effects of PLP were also observed from the increased expression levels of acinar cells are amylase -2.01, neurogenin-3-9.51, PDX-1- 23.6 and insulin-13.5 in group 3 compared to group 1. The specificity of PLP&rsquo;s response was confirmed by amino oxy acetic acid (AOAA), a specific PLP inhibitor. The increased amylase protein localization with PLP was confirmed by confocal microscopy. Insulin secretion efficiency of acinar cells was observed to be 6.13 folds higher at basal and 24.63 fold higher at stimulated levels in group3 compared to group1. Significance: Our results advocate the antioxidant and cytoprotective effects of PLP on the pancreatic acinar cell along with increased pancreatic marker expressions of amylase,PDX-1, neurogenin-3 and insulin proteins.

Background: Hypothyroidism is a frequently observed comorbidity in patients with chronic heart failure (CHF), possibly giving rise to unfavorable outcomes. Aim: The aim of the study was to evaluate the impact of TSH changes over time on cardiac function and prognosis of outpatients with CHF. Methods: Patients underwent clinical, electrocardiographic, and echocardiographic evaluations at baseline and after 12 months. Moreover, blood chemistry tests were performed to evaluate renal function, cardiac biomarkers, fT3, fT4, and TSH levels. Based on TSH serum levels, patients were retrospectively classified into four categories: Group 1, patients with improved thyroid function at one-year follow up vs. baseline; Group 2, patients with stable and mildly high TSH values (3.74 – 10 mUI/L); Group 3, patients with worsening thyroid function; Euthyroid patients Group, TSH levels within the normal range of reference at baseline as well as at 12 months follow-up. We considered as end-points: one-year changes of laboratory and echocardiographic parameters; hospitalizations due to worsening of HF (acute decompensated heart failure - ADHF); death for all causes. Results: Among 257 patients, 174 (67.7%) were euthyroid at baseline and after 12 months. Group 1 patients (n. 22, 8.6%) showed a significant improvement in systolic and diastolic function, filling pressures, NT-proBNP and Galectin-3. Group 2 patients (n. 34, 13.2%) did not exhibit significant modifications in studied parameters. Group 3 patients (n. 27, 10.5%) showed worsening of diastolic function and NT-proBNP and a greater risk of ADHF (HR: 2.12; 95%CI: 1.20-3.74; p: 0.009) and death (HR: 4.05; 95%CI: 2.01-8.15; p<0.001). Conclusion: In patients with CHF, changes in thyroid function over time influenced echocardiographic parameters and biomarkers reflecting modifications of cardiac function and prognosis, thus suggesting the clinical relevance of thyroid deficiency screening and correction.

The purpose of this study was to evaluate in vitro the dentin permeability of the deciduous pulp chamber floor after employing 2-octyl cyanoacrylate and Er:YAG laser. Twenty four deciduous molars were used, divided into four groups. After chemical-surgical preparation each group received a different treatment: Group 1 - control, without treatment; Group 2 - the floor of the pulp chamber was covered with a fine layer of 2-octyl cyanoacrylate; Group 3 - the floor of the pulp chamber was irradiated with Er:YAG laser (250 mJ, 10 Hz for 30 seconds, 80 J of energy and 320 pulses), and covered with a fine layer of 2-octyl cyanoacrylate; and Group 4 - the floor of the pulp chamber was irradiated with Er:YAG laser set at the parameters already described. After that the specimens received application of 0.5% methylene blue, for 15 minutes. The teeth were cut, photographed, and the digitalized images were analyzed using the ImageLab program. The results obtained were submitted to statistical analysis. Group 4 (Er:YAG) presented the largest averages in percentage of dye penetration area (19.5%), followed by Group 1 (11.1%), Group 3 (1.4%) and Group 2 (0.2%). The experimental model allowed to conclude that the specimens conditioned with 2-octyl cyanoacrylate (Group 2) and Er:YAG laser associated to 2-octyl cyanoacrylate (Group 3) presented a decrease in permeability, and the specimens treated with Er:YAG laser (Group 4) presented an increase in permeability of the analyzed area.

Background: Premature ovarian insufficiency (POI) is a challenging disease, with limited treatment options at the moment. Umbilical cord blood mesenchymal stem cells (UCMSCs) have demonstrated promising regenerative abilities in several diseases including POI. Materials and Method: A pre-clinical murine case versus vehicle control randomized study. Two experiments ran in parallel in each of the three groups. The first was to prove the ability of UCMSCs in restoring ovarian functions. The second was to prove improved fertility. A total of 36 mice were randomly assigned; 6 mice into each of 3 groups for two experiments. Group 1 (control), group 2 (sham chemotherapy), group 3 (stem cells). Results: In the first experiment, post-UCMSCs treatment (group 3) showed signs of restored ovarian function in the form of increased ovarian weight and estrogen-dependent organs (liver, uterus), increased follicular number, and a significant decrease in FSH serum levels (p < 0.05) compared to group 2, and anti-Mullerian hormone (AMH) serum levels increased (p < 0.05) in group 3 versus group 2. Immuno-histochemistry analysis demonstrated a higher expression of AMH, follicle stimulating hormone receptor (FSHR) and Inhibin A in the growing follicles of group 3 versus group 2. In the second experiment, post-UCMSCs treatment (group 3) pregnancy rates were higher than group 2, however, they were still lower than group 1. Conclusion: We demonstrated the ability of UCMSCs to restore fertility in female cancer survivors with POI and as another source of stem cells with therapeutic potentials.

Epidural fibrosis (EF) is a common complication for the patients who underwent laminectomy. Recently, EF is thought to cause recurrent postoperative pain after laminectomy. Resveratrol has been shown to exert its anti-inflammatory, antifibrotic, and antiproliferative multifaceted properties. The object of this study was to investigate the effects of resveratrol on the prevention of postlaminectomy EF formation in laminectomy rats. A controlled double-blinded study was performed on 60 healthy adult Sprague-Dawley rats that underwent lumbar laminectomy at the L1-L2 levels. They were divided randomly into 3 groups (1, 2, and 3) of 20 rats each—group 1: resveratrol treatment group; group 2: resveratrol dilution saline treatment group; group 3: sham group (rats underwent laminectomy without treatment). All rats were killed 4 weeks after operation. The Rydell score, hydroxyproline content, vimentin cells density, fibroblasts density, and inflammatory factors expressional levels all suggested better results in resveratrol group than the other two groups. Resveratrol is able to inhibit fibroblasts proliferation, and TGF-β1 and IL-6 expressions and prevent epidural fibrosis in postlaminectomy rat.
