ABSTRACT Objective: To determine the serum levels of malondialdehyde and nitrite in patients with sickle cell anemia treated or not with hydroxyurea in outpatient's setting. Methods: Of the 65 patients with sickle cell anemia selected for the study, 51 were not treated with hydroxyurea (Group 1), 14 made chronic use of hydroxyurea (Group 2) and 20 individuals had no hemoglobinopathies (Control Group). Results: The Control Group had a lower and more homogeneous concentration of malondialdehyde levels as compared to the other groups. The results of Groups 1 and 2 showed increased values of malondialdehyde levels when compared to the Control Group. Considering the values of Groups 1 and 2, there were no significant changes in the malondialdehyde levels. There was no significant difference in the serum levels of nitrite between the groups. Group 2 presented a statistically significant correlation between serum malondialdehyde levels and the clinical variables investigated. In turn, Group 1 showed correlation only with occurrence of three or more vaso-occlusive crises. There was no correlation between nitrite levels and the clinical variables. Conclusion: The results revealed that during the pathogenesis of sickle cell anemia, an increase in lipid peroxidation was observed. On the other hand, no changes in oxidative parameters were detected during treatment with hydroxyurea, probably due to the short period of treatment of the patients studied.

ObjectivesThe aim of this study was to establish quantitative values for asymptomatic and symptomatic Achilles tendons.DesignCohort study with a single (cross-sectional) time point of patients diagnosed with unilateral Achilles tendinopathy and an asymptomatic group with comparative homogeneity.MethodsA sample of 50 participants: 25 diagnosed with symptomatic unilateral Achilles tendinopathy (AT group) and 25 with asymptomatic Achilles tendons (control group 2). The asymptomatic side of the AT group was used as a control (control group 1). Measurements at 2 cm intervals on the tendon from its insertion at the calcaneum up to the musculotendinous junction were taken non-weight bearing (NWB) and weight bearing (WB) using the MyotonPRO.ResultsThere was a significant (p<0.005) decrease in natural oscillation frequency (F) at points 2, 3 and 4 of the AT group (NWB condition) and points 2 and 3 for the WB condition. There was a significant (p<0.005) increase in logarithmic decrement (D) at points 2 and 3 signifying a decrease in elasticity. Dynamic stiffness (S) was significantly (p<0.005) reduced in the AT group at points 2 and 3 WB and point 3 WB. There was no significant difference in creep (C) observed between the symptomatic and asymptomatic tendons. There was a significant (p<0.005) increase in mechanical stress relaxation time (R) at point 2 NWB.There was a correlation between body weight and gender on tendon mechanics, with the symptomatic tendons. No significant differences were observed between the control group 1 and control group 2.ConclusionsThe MyotonPRO measured decreased stiffness over a section of the tendon corresponding clinically with Achilles tendinopathy. This may have potential in identifying risk of injury and informing rehabilitation, however further extensive research is required to generate baseline data for specific population groups monitoring variables over time. Age, gender and body mass index appear to have some bearing on the mechanical properties of the tendon but mainly in the tendinopathy group.

The aim of this study was to investigate the frequency of nocturnal sperm emissions (NSE) in varicocele patients after varicocele surgery. A total of 127 patients, 96 varicocele (Group 1) and 31 patients with inguinal hernia (Group 2) were included in this study. Mean age, laterality of surgical procedures, spermiogram results, marital status, and postoperative serum hormone levels were noted for all patients. Two groups were compared in terms of Beck depression score (BDS) and anxiety scores (AS). The frequency of NSE and libido changes in the patients during 10 days postoperatively was evaluated. The number of the patients who had NSE and increased libido were significantly higher in the varicocelectomy group when compared with the control group. No significant difference was noted between the groups in terms of BDS, AS, and serum hormone levels. No association was reported between BDS, AS, and serum hormone levels and the presence of NSE in Group 1. The incidence of NSE was higher in younger men. Increased libido was significantly associated with NSE in Group 1. Cord dissection during surgery may be a factor on increased frequency of NSEs in varicocele patients.

A randomized, controlled clinical trial was performed to determine whether individualized dosing by use of Bayesian pharmacokinetic modeling could decrease nephrotoxicity accosted with aminoglycoside therapy. Two hundred forty-three patients receiving aminoglycosides for suspected or proven infection were randomly assigned to one of three groups: usual physician-directed dosing (Group 1), pharmacist-assisted dosing (Group 2), or pharmacist-directed dosing (Group 3). Dosing in Groups 2 and 3 was based on a Bayesian pharmacokinetic dosing program, whereas Group 1 served as the control group. Individualized dosing resulted in higher mean postinfusion (peak) serum aminoglycoside levels, higher ratios of mean peak level to minimum inhibitory concentration (peak/MIC ratios), and a trend toward lower trough serum levels. Milligrams per dose were higher and number of doses per day was lower in the pharmacist-dosed groups. However, the incidence of nephrotoxicity (> or = 100% increase in serum creatinine) was not different among the three groups (16, 27, and 16% in Groups 1, 2, and 3, respectively). Similarly, severity of toxicity was not affected by the dosing intervention. Risk factors for toxicity included duration of therapy, shock, treatment with furosemide, older age, and liver disease. After controlling for these factors, the dosing intervention still had no effect on nephrotoxicity. It was concluded that Bayesian pharmacokinetic dosing did not decrease the risk of nephrotoxicity associated with aminoglycoside therapy.

Study Objective: To know about the effects of cryotherapy and active stretching together and active stretching alone for improving hamstring flexibility in asymptomatic individuals. Method: 22 subjects were participated in study of the age 18 to 40. Subjects were randomly and equally assigned to static stretching and cryotherapy (group 1) and only active stretching (group 2). Subjects in each group were given stretching and cryotherapy for three weeks. Pre and post assessment of ROM was measured by the KEA, SLR and Sit and reach test. Results: After three weeks of intervention there was a significant difference between pre intervention and post intervention score in both the group but in group 1 showed significant difference between KEA, SLR and SRT variables. Conclusion: Subject who received active stretching and cryotherapy showed better improvement than the control group who received only active stretching. Hence it can be concluded that active stretching along with cryotherapy can improve hamstring flexibility than the active stretching only. Key words: Cryotherapy, flexibility, ROM, active stretching.

Abstract Background: Premature ovarian failure is among the most important side effects of chemotherapy during reproductive period. Preserving ovarian function is gradually gaining importance during oncologic treatment. The present study aims to investigate the potential of melatonin to protect from cisplatin-induced ovarian toxicity in rats. Twenty nine female rats were divided to three groups: Saline control group (Group 1), cisplatin group (Group 2), and cisplatin+melatonin group (Group 3). While the rats in Groups 2 and 3 were administered 5 mg/kg single dose of cisplatin via intra-peritoneal (IP) route, the rats in Group 3 were started on melatonin (20 mg/kg IP) before cisplatin administration and continued during 3 consecutive days. Ovaries were removed one week after cisplatin administration in all groups. Blood samples were obtained before the rats were decapited. Histological evaluation, follicle count, and classification were performed. TAp63 mRNA expression was evaluated using mRNA extraction and real-time polymerase chain reaction (PCR) method. Serum estradiol (E2) and anti-mullerian hormone (AMH) values were measured with enzyme immune-assay technology. Results: While primordial follicles were seen to decrease in Group 2 as compared to Group 1 (p:0.023), primordial follicle count was observed to be preserved significantly in melatonin group as compared to Group 2 (p:0.047). Moreover, cisplatin-induced histo-pathological morphology was preserved in favor of normal histology in melatonin group. A significant difference was not observed between groups with regard to mean serum AMH and E2 values (p:0.102 and p:0.411, respectively). While TAp63 gene expression significantly increased in Group 2 as compared to control group (p:0.001), we did not detect a statistically significant difference in cisplatin+melatonin group, although gene expression decreased (p:0.34). Conclusion: We conclude that concurrent administration of melatonin and cisplatin may protect from ovarian damage.

Introduction: Sickle cell anemia is a disease characterized by a wide vaso-occlusive incident from micro-vascular incident to muscularactivity. The cochlear function can also get affected by this vaso-occlusion. Objective: It is aimed at determining what kind of effects sickle cell anemia has on hearing and balance system. Methods: This study has been conducted on 46 patients with sickle cell anemia and 45 healthy individuals. For all participants, their pure tone hearing thresholds and videonystagmography (VNG) findings have been determined in 17 frequencies between 125–16.000 Hz. Results: All hearing thresholds between 125 and 16,000 Hz, pure tone averages of patients with sickle cell anemia have been found statistically significant to be higher than the corresponding values in the control group(p < 0.05). The normal hearing rate of patients with sickle cell anemia has been determined to be 71.1% conductive hearing loss (CHL) to be 4.4%, sensorineural hearing loss (SNHL) to be 22.2%, and mixed type hearing loss to be 2.2% in right ear; the normal hearing rate has been determined to be 71.1%, CHL to be 2.2%, SNHL to be 22.2%, and mixed type hearing loss to be 4.4% in left ear. Statistically significant difference has not been found between head shake, spontaneous nystagmus, optokinetic, tracking test batteries, static and dynamic positional tests used in VNG, saccade accuracy and saccade peak velocity, which are saccadic test findings of 2 groups. However, saccadic latency, which is a saccadic test finding, has been determined to be longer in patients with sickle cell anemia in comparison to the control group. Conclusion: While sickle cell anemia causes hearing deficits, it does not have any effect on the central or peripheral vestibular system.

SummaryIntroduction: During the last years, many endovascular techniques have been developed in order to eliminate not only the reflux in stem veins but in perforating veins and their tributaries, too.Aim: The aim of this study was to use endo -vascular RFITT and the foam sclerotherapy for the occlusion of perforating veins as the prime source of reflux and their tributaries.Material and Methods: The Celon method was used for the thermal treatment. Polydocalon with the concentration 1% and 2% with DSS technique was used for the foam sclerotherapy. The RFITT was accomplished in 127 perforating veins in total. This group was divided into three subgroups. The first one consists of patients where only RFITT was carried out (n= 41), in the second, there were patients with RFITT realized with sclerotherapy during one session (n= 48), in the third, RFITT was completed with sclerotherapy in one month after the RFITT intervention (n= 38). The control group included perforating veins treated only with sclerotherapy (n= 81). The power setting 6W was used on the generator during the RFITT with CelonProSurge micro and 18W for usage of Celon ProCurve probe.Results: The effectiveness of the procedure in the group 1 was 8.8%, in the group two 93.7%, in the group three 92.1% and in the control group 76.5% in one year follow up. There was no significant difference between the effectiveness in groups 1, 2 and 3. The marginal difference was among all three groups with RFITT and the control group. Significant differences were in the parameter of the extinction of visible varicose veins with the reflux from perforators. The extinction was faster in group 3 than in group 2 and in the control group and the slowest was in group 1. The significant difference was observed between groups 2 and 3 compared with group 1 and the margin difference was between groups 2 and 3 compared with the control group. No significant difference was observed between groups 1 and the control group.Conclusions: All procedures are effective. The most important is the combination of RFITT and the sclerotherapy one month after thermal intervention. This is associated with a low risk of recanalization and the fastest extinction of visible varicose veins.

Introduction:Absence epilepsy is the most common primary generalized epilepsy syndrome encountered in pediatric practice. Treatment is pharmacologically specific and usually successful with a single medication. The objective of this study was to identify any clinical or electroencephalographic features at initial presentation in a consecutive cohort of children with absence epilepsy that may be associated with the need for a second medication.Methods:A computerized pediatric neurology database (1991-2007 inclusive) was retrospectively searched for all patients with typical absence seizures, 3 Hz spike and wave on EEG and no apparent symptomatic etiology who were over the age of two years at seizure onset with at least one year of follow-up. All such children were then divided into two groups; a) those requiring a single medication for seizure control (Group 1), and b) those requiring two medications for seizure control despite optimal management with the initial medication as determined by serum drug monitoring (Group 2). Clinical and electrographic features evident at diagnosis were then contrasted between Group 1 and 2.Results:Seventy-five children with absence seizures were initially identified with 52 meeting the study’s inclusion and none of the exclusion criteria. Of these 52 children, 43 required a single medication for seizure control (Group 1), while 9 required two or more medications for seizure control (Group 2). A significant difference (p<0.05) was apparent between Group 1 and 2 with respect to gender (16/43 males vs 8/9 males) and mean age of diagnosis (8.19 years +/− 3.00 vs 6.06 years +/− 2.22). Age of onset of seizures, interval duration of seizures prior to treatment initiation, duration of seizures, presence of automatisms, family history, presence of co-morbid conditions and EEG findings were not found to be significantly different between the two Groups.Conclusions:Male gender and an earlier age of diagnosis is associated with the need for two medications for seizure control in children with absence epilepsy. This observation may suggest the need for more intensive early programmatic follow-up for young male children with newly diagnosed absence epilepsy to effect more rapid attainment of seizure control.
