Intensive voice treatment (the Lee Silverman Voice Treatment [LSVT®LOUD]) for individuals with Wilson's disease and adult cerebral palsy: two case reports.

Objective: In this case report, we aimed to examine the effects of an intensive voice treatment (the Lee Silverman Voice Treatment [LSVT®LOUD]) for Wilson's disease (WD), and adult cerebral palsy (CP), and dysarthria.Method: The participants received LSVT®LOUD four times a week for 4 weeks. Acoustic, perceptual (GRBAS) analyses were performed and data from the Voice Handicap Index (VHI) were obtained before and after treatment.Results: Besides the Harmonics-to Noise Ratio (HNR) value (dB) of the participant with WD, for both participants' fundamental frequencies (Hz), jitter (%), and shimmer (%) values showed significant differences (p < .05) after therapy. Both participants showed significant improvements (p < .05) in the duration (s) and the sound pressure level (dB, SPL) of sustained vowel phonation (/a/), in SPL (dB) of pitch range (high and low /a/) and reading and conversation (p < .01). There was a positive improvement in the high-frequency values (Hz) of both participants but not in the low-frequency values (Hz) in the participant with WD. Perceptual analysis with GRBAS judgements of sustained vowel (/a/) and paragraph reading of two participants also showed improvement. After therapy, perceived loudness of the participants' voice increased.Conclusions: The findings provide some preliminary observations that the individuals with WD and the adult individuals with CP can respond positively to intensive speech treatment such as LSVT®LOUD. Further studies are needed to investigate speech treatments specific to WD and adult CP.

Acoustic Voice Analysis of Young Turkish Speakers.

OBJECTIVE/HYPOTHESIS: One of the objective assessments of voice is acoustic analysis, particularly, the parameters fundamental frequency (F0), jitter, shimmer, and noise-to-harmonics ratio (NHR). Because the normative data for healthy native Turkish male and female speakers are lacking in the literature, this study aimed to obtain F0, perturbation parameters, and NHR in three sustained vowels (/Λ/, /i/, and /u/) among young Turkish speaking adults. METHODS: The native Turkish speakers with normal voice aged between 18 and 32 years were included in the study (44 women, 39 men). Voice samples were recorded using Computerized Speech Lab, and data were analyzed with the statistics software SPSS Statistics 21.0 (IBM Corp., Armonk, NY, USA). RESULTS: The F0 values of vowels /Λ/, /i/, and /u/ were greater for women (239.78 Hz, 251.97 Hz, and 250.29 Hz, respectively) than for men (127.11 Hz, 137.23 Hz, and 134.15 Hz, respectively). All shimmer values for all vowels and jitter values for /Λ/ and /u/ were found significantly low in men; however, no difference was found for jitter values of /i/ between genders. There is no effect of gender on NHR. Only in women, NHR of high vowels was found to be lower than that of vowel /Λ/. CONCLUSIONS: There is a significant difference for F0 values between the genders as expected. Comparisons of perturbation values were significantly different for some pairs of vowels. There was no significant difference between NHR values between the genders. These findings can be compared with Turkish speakers who have different voice disorders for the further studies.

Cytotoxicity of local anesthetics to rats' articular cartilage: an experimental study.

OBJECTIVE: The aim of this study was to evaluate the effects of both in vivo and in vitro bupivacaine, levobupivacaine and tramadol on articular cartilage and chondrocytes in experimental rat models. METHODS: Thirty mature Sprague Dawley rats weighing 230-300 g were randomized into 3 groups. Bupivacaine (Group 1), levobupivacaine (Group 2) and tramadol (Group 3) were injected into the right knee joints and a physiological 0.9% saline into the left. From each group, 5 rats were executed 48 hours following drug administration after 5 and 10 days. The specimens were fixed, decalcified and stained with hematoxylin & eosin and toluidine blue. All samples were histopathologically evaluated according to the recommendation of ICRS' osteoarthritis and cartilage histopathology grading and staging system. Articular cartilage cells of the rats were cultured and seeded into cell culture flasks. Cartilage cell seeded samples (104 cells/ml) were incubated in three different anesthetic agents (0.5%); bupivacaine, levobupivacaine, and tramadol, respectively. CellTiter 96(®) Non-Radioactive Cell Proliferation (MTS) assay was used to determine the cell density on the samples. RESULTS: Statistically significant higher OARSI grades and OA stage and scores were detected when comparing the group injected with levobupivacaine and executed after 10 days with the levobupivacaine injected group killed after 48 hours (p<0.01 [p=0.008]). Although, statistical analysis could not be done due to insufficient number of samples in the in vitro part of the experiment, it can be concluded that tramadol is cytotoxic to rat chondrocyte in vitro after 30 min of exposure. Additionally, cell numbers in both the bupivacaine and levobupivacaine treated wells showed decrease throughout 15, 30 and 60 minute exposures. CONCLUSION: Although chondrotoxicity of bupivacaine was less harmful than levobupivacaine and tramadol, these findings suggest that local anesthetics may negatively affect articular cartilage and chondrocytes.

Role of papaverine hydrochloride administration in patients with intractable renal colic: randomized prospective trial.

OBJECTIVES: To evaluate the therapeutic effect of papaverine hydrochloride in the treatment of patients with renal colic pain unresponsive to conventional treatment. METHODS: From March 2007 to January 2008, a total of 561 patients with severe renal colic pain due to a ureteral stone were treated with conventional agents (hyoscine-N-butylbromide and diclofenac sodium) in the emergency and urology departments. Of these 561 patients, 110, with no response to the treatment and persistent severe pain, were randomized into 3 groups for additional treatment. The patients in group 1 (n = 37) received intravenous hyoscine-N-butylbromide, those in group 2 (n = 37) received papaverine hydrochloride, and those in group 3 (n = 36) received pethidine. Before and after treatment, all patients completed a visual analog scale (VAS) questionnaire, with a scale of 0 (no pain) to 10 (maximal complaint), to measure their subjective pain. The mean VAS score of each group was compared with that of the other groups. RESULTS: The pretreatment mean VAS scores of all 3 groups were not significantly different statistically from each other (4.02 +/- 1.20, 4.36 +/- 1.97, and 4.27 +/- 1.50; P > .05). However, after treatment, the mean VAS scores of the patients treated with papaverine (0.93 +/- 0.29) and pethidine (0.81 +/- 0.38) were significantly different from those of the hycosine group (3.67 +/- 2.21; P < .001). However, the mean VAS scores of groups 2 and 3 were comparable (P = .67). Unlike opioids, no papaverine-related severe side effects were observed. CONCLUSIONS: Our results indicate that papaverine hydrochloride can used in an effective manner in the management of renal colic pain in patients unresponsive to commonly used conventional agents.

Intraarticular tramadol plus pericapsular incisional bupivacaine provides better analgesia than intraarticular plus pericapsular incisional bupivacaine after outpatient arthroscopic partial meniscectomy.

Postoperative analgesic effects of intraarticular tramadol plus periarticular bupivacaine, and intraarticular plus periarticular bupivacaine injections after day-case arthroscopic partial meniscectomy were compared. Seventy-four ASA I/II patients undergoing arthroscopic partial meniscectomy, performed by a single surgeon under general anesthesia were assigned in a randomized, double-blinded manner into two groups: Group TB (n = 41) received intraarticular 100 mg of tramadol in 20 ml normal saline and periarticular incisional injection of 10 ml bupivacaine 0.5%. Group BB (n = 33) received intraarticular 20 ml 0.25% and periarticular incisional 10 ml 0.5% bupivacaine injections. The injections were performed immediately after the portal closures. Pain was assessed with visual analog scale (VAS) at 0, 15, 30 min and at 1, 2, 4 h at rest and active 90 degrees knee flexion by a blinded observer. The first additional analgesic requirement time was recorded. The patients were discharged the same day with a prescription for paracetamol as required, up to six tablets a day and questioned for analgesic use and pain score at 24 h. VAS scores at rest at 15, 30 min and at movement at 0, 15, 30 min were lower in group TB (P < 0.05). First time requiring additional analgesia was lower in group TB (17.1 +/- 21.9, 33.8 +/- 26.6) (P < 0.05) and total paracetamol dose at the end of 24 h was 1.2 +/- 1.5 g in group BB and 0.9 +/- 1.3 g in group TB (P < 0.05). Intraarticular tramadol plus periarticular bupivacaine combination provides better pain relief and less analgesic requirement following arthroscopic outpatient partial meniscectomy surgery.
