Abstract
BACKGROUND Gender-affirming colovaginoplasty (GACv) presents excellent postoperative results. However, neovaginal spasms, reported as painful cramps, can affect the sexual life of patients. AIM The study sought to describe an innovative surgical technique and evaluate its impact on the prevention and treatment of neovaginal spasms. METHODS This was a single-center prospective observational study with 2 series of patients: (1) patients who underwent GACv with double myotomy (DM) for spasm prevention (series A), in which longitudinal myotomies were performed across the defunctionalized colon, transecting the taenias, and resecting 2 strips of the intestinal muscle layer of approximately 1- to 2-mm wide and tall, leaving intact colonic tissue between strips; and (2) patients who reported neovaginal spasms in whom intravaginal-DM was performed as treatment surgery (series B), in which the posterior wall of the neovagina was dissected from the rectum and transected by longitudinal myotomies, resecting 2 strips of endoluminal mucosa and submucosal muscle of approximately 1- to 2-mm wide and tall, and the colonic mucosa was subsequently closed. OUTCOMES Patient-reported outcomes and neovaginal examination were performed following standardized protocols. RESULTS In series A, 177 patients underwent GACv with the DM technique and were prospectively followed for a median time of 18 months (interquartile range, 13-60 months). No patients reported neovaginal spasms. In series B, 18 patients who reported neovaginal spasms after GACv were treated with intravaginal DM. After a median time of 35 months (interquartile range, 26-45 months), 83% (n = 15 of 18) reported remission of symptoms. CLINICAL IMPLICATIONS Double longitudinal myotomy performed on the derived portion of the colon in colovaginoplasty is an easy-to-perform and safe technique that may prevent and treat postoperative neovaginal spasms. STRENGTHS AND LIMITATIONS Our results presented certain limitations, mainly associated with a low prevalence of neovaginal spasms, which, being of personal perception, can be underdiagnosed. To the same extent, the fact that it is a monocentric experience limits the possibility of extrapolating it to other centers. Moreover, a more trained surgical team may be the cause of fewer postoperative complications. On the other hand, the fact of being a reference center for gender-affirming surgery, having our procedures protocolized, and the prospective nature of the study allowed us to obtain a certain homogeneity and granularity of the results. CONCLUSION DM is a safe procedure and appears to be highly effective for the prevention and treatment of neovaginal spasms after GACv. Routine use of this technique does not increase the operating time or postoperative complications. Multicenter, prospective studies are required to validate our results.

Abstract
The radial artery (RA) access is currently the gold standard to perform cardiovascular interventions. One of the more common limitations is radial artery spasm which is an often complication interrupting the procedure. Common risk factors associated with spasm include female gender, periprocedural anxiety, multiple puncture attempts, distal radial access, diabetes, hypertension, and smoking. The mechanism of spasm is complex and includes calmodulin and rho-kinase pathways leading to the smooth muscle contraction. Proper hydration, anxiety management, and adequate local anesthesia should be applied to decrease the risk of spasms. Radial cocktail is often used to prevent spasm. Its composition differs between catheterization laboratories and the effect is attributed either to the verapamil or nitroglycerin, with contradictory results of different studies. Balbay maneuver is also an effective mean of prevention. Hydrophilic-coated devices can be used both to avoid spasms or reverse them. Radial angiography can be used to differentiate spasm from a tortuosity and choose proper method of management. Fasudil, a Rho-kinase inhibitor, has been reported as a pharmacological method to prevent spasm and reverse radial artery spasm.

Abstract
Radial artery spasm (RAS) is the most common cause of transradial access site crossover and is a common intra-procedural complication. RAS incidence can lead to radial artery occlusion (RAO) postprocedure, preventing the radial artery as a future access site. We evaluated the efficacy of nitroglycerin preventing RAS and RAO during transradial catheterization discussing the different routes of administration, including topical, subcutaneous, and intra-arterial. A systematic review and meta-analysis included all relevant articles until April 23, 2022. We searched six databases Google Scholar, Web of Science, SCOPUS, EMBASE, PubMed (MEDLINE), and CENTRAL. We registered our review protocol in PROSPERO with ID: CRD42022330356. We included 11 trials with 5814 patients. Compared to placebo, the pooled analysis favored subcutaneous nitroglycerin in preventing RAS (risk ratio [RR]: 0.57 with 95% confidence interval [CI] [0.43-0.77], p = .0003) and RAO (RR: 0.39 with 95% CI [0.16-0.98], p = .05). In contrast to the intra-arterial nitroglycerin that showed nonstatistically significant results in preventing RAS and RAO (RR: 0.8 with 95% CI [0.63-1.02], p = .07)- (RR: 0.78 with 95% CI [0.6-1.01], p = .06)), respectively. Also, topical nitroglycerin did not prevent RAS (RR: 0.73 with 95% CI [0.42-1.24], p = .24). Compared with placebo, subcutaneous nitroglycerin during transradial catheterization reduced the incidence of RAS and RAO. Meanwhile, Intra-arterial and topical nitroglycerin did not show statistically significant outcomes. Subcutaneous nitroglycerin may be a practical and cost-effective technique to facilitate transradial catheterization; however, more RCTs are needed to evaluate the subcutaneous versus intra-arterial nitroglycerin administration.

Abstract
A recent guideline has recommended the radial artery as the access site for coronary catheterization due to lower risk of bleeding and vascular complications. However, the transradial approach is not necessarily easy for interventionalists due to the smaller vessel diameter and more frequent occurrence of vasospasm induced by the procedure. By using the measurement in ultrasound, a previous study demonstrated that subcutaneous nitroglycerin injection at the radial artery puncture site dilated the radial artery, and that a patch was also easier and less invasive. The current case suggests the applicability of a nitroglycerin transdermal patch to prevent vasospasm via local transdermal absorption into the arterial wall; its use may lead to a higher success rate for the transradial approach, especially in patients who had experienced radial artery vasospasm.

Abstract
BACKGROUND The modern study of the traditional Chinese medicine (TCM) compound recipes is a complex issue because of the large number of components in the recipes that would produce several metabolites after entering the body. The TCM compound recipes are known to have the advantage of synergistic treatment by multiple targets due to diverse components. Therefore, a research method that can reflect the overall effect of compounds with multi-components is essential. The pharmacological studies of the classic TCM compound recipes mainly use the sero-pharmacological method. It is a semi-in vivo study method, and the drug to be tested in the in vitro experiment is the drug-containing serum from the model animals (the drug to be tested is a mixed drug system containing the prototype drugs in animal bodies that have pharmacodynamic effects and the metabolites). Herein, a safe and effective external TCM recipe was used to develop another semi-in vivo experimental method to reflect the overall effects of TCM. AIM To observe the effects of in-vitro intestinal absorption liquid of aqueous extracts of the TCM compound recipe-Guangtongxiao foam aerosol (Guangtongxiao)-on the tension of isolated rectal rings of mouse and investigate the underlying mechanisms of antispasmodic and amelioration of muscular spasm-induced pain. METHODS Intestinal absorption liquid of the Guangtongxiao aqueous extract at the five time points (30, 45, 75, 105, and 120 min) was prepared using a non-everted gut sac method. The isolated rectal rings of mice were prepared by pre-contraction using potassium chloride (KCl) or acetylcholine chloride (ACh) to make steady contraction. The intestinal absorption liquid were added cumulatively to the sink with the constricted rectal rings. The effects of the five groups of the intestinal absorption liquid with different drug concentration were observed on the tension of the isolated rectal rings. Then the ex vivo perfusion of the mouse rectal ring was performed as same as Guangtongxiao intestinal absorption liquid experiments, and the effects of two major components of Guangtongxiao, paeoniflorin (Pae) and tetrahydropalmatine (THP), on the rectal ring pre-treated with high concentration of KCl and ACh to induce contraction were studied. RESULTS The relaxation rate of the five groups of the intestinal canals increased significantly with 3200 μL cumulative sample volume as compared to the blank group (P < 0.01). It suggested that the relaxation activity of the intestinal absorption liquid enhanced significantly with the prolongation of the interaction between isolated rectal rings and intestinal absorption liquid in a time-dependent manner. Also, significant differences were detected while comparing between the 120-min intestinal absorption liquid group and the blank group with respect to various cumulative sampling volumes (P < 0.01). In addition, the intestinal relaxation rate elevated gradually with the increase in sampling volume, indicating that the concentrations of active substances in the intestinal absorption liquid prepared by the non-everted gut sac model increased and the intestinal relaxation activity was enhanced with the prolongation of the absorption time in a dose-dependent manner. And Pae and THP in a concentration-dependent manner caused relaxation of the rectal ring, which is pretreated with high K+(KCl) and ACh to induce contraction. The EC50 of Pae and THP was 8.67 × 10-5 M (6.68 × 10-5-1.13 × 10-4) and 1.41 × 10-4 M (1.24 × 10-4-1.61 × 10-4) in the contraction model induced by KCl, and was 6.15 × 10-5 M (4.47 × 10-5-8.45 × 10-5), and 1.31 × 10-4 M(1.22 × 10-4-1.42 × 10-4) in the model induced by ACh, respectively. CONCLUSION The intestinal absorption liquid of Guangtongxiao exerted a remarkable relaxation activity for the rectal rings, and relaxation of the smooth muscle tension might be one of the antispasmodic mechanisms of Guangtongxiao compound recipe. Also, adopting a semi-in-vivo experimental method to study the efficacy of topical external TCM recipe medicine is optimal.

Abstract
RATIONALE Transradial access (TRA) is common for cardiac catheterization, but radial artery spasm (RAS) is suggested to be highlighted. Severe radical artery spasm could be solved by a relative novel approach called "sheathless technique," using a Tiger diagnostic catheter. PATIENT CONCERNS A 73-year-old woman presented to our institution with a recurrent feeling of discomfort in her chest. Her electrocardiogram showed ST segment depression. Her medical history indicated arterial hypertension, diabetes, and chronic renal failure. She was on hemodialysis for 5 years for the management of renal problems. Five stents were implanted from femoral access in another hospital via 2 percutaneous coronary interventions. The patient agreed to angiography this time and wanted a more comfortable solution. DIAGNOSIS Recurrent exertional angina was confirmed based on the chief complaint, electrocardiogram, and history. INTERVENTIONS After a successful radial artery puncture, a 6F arterial sheath pipe and a 5F Tiger diagnostic ductus could only advance slightly because of the RAS. Glonoin and verapamil functioned with the help of the radial sheath, and systemic nitroglycerin was applied later but had a negative outcome. Warm covers were positioned on the antebrachium, but no relief was reported.The "homemade sheathless technique" was applied. The 5F tube was held, and the 6F sheath was withdrawn. A blade was used to damage the sheath in reverse, and the excess sheath tube was removed. OUTCOMES The diagnostic catheter was successfully advanced to the ascending aorta, enabling left main and right coronary engagement and angiography. No significant coronary lesion was observed. The patient was discharged 3 days after angiography. Moreover, no complications were observed. A follow-up for 1 month after discharge also showed no complications. LESSONS Severe RAS causing failure of TRA is frequent in the transradial catheterization procedure. The sheathless technique may be useful in relieving spasm when other measures fail.

Abstract
This paper proposes a new clonus management system that integrates sit-to-stand (STS) learning with informatics and physical methods. Clonus is an involuntary muscle spasm, which often interferes with motor learning or the training of chronic patients. A conventional ankle-foot orthosis makes it difficult for patients to control the onset of clonus or to improve it. A new system with an original orthosis can reduce the occurrence of clonus by the physical constraint of the ankle by firmly placing the heel of the affected side on the ground. This system also provides a ground reaction force of the heel because clonus hardly occurs when the heel is placed on the ground. The system supports STS movement by linearly moving the seat up and down when users place the heel of the affected side on the ground. Using this system, users can learn how to perform the STS movement while managing their clonus. Testing its effect on a stroke patient confirmed that the system relieves the onset of clonus and reduces the frequency with which clonus occurs during STS learning. In addition, the results of continuous learning showed that the patient could perform the STS movement without the occurrence of clonus even without using the developed orthosis. Here we discuss the results from the viewpoints of human-machine interaction and the relationship between nervous and peripheral systems. The proposed clonus management system may promote the improvement of chronic patients with clonus.

Abstract
BACKGROUND The uptake of percutaneous coronary procedures via the radial artery has increased internationally due to the decreased risk of complications and increased patient satisfaction. The increased susceptibility of the radial artery to spasm however presents a potential risk for procedural failure. Although most experts agree on the need for prophylactic medications to reduce radial artery spasm, currently there is inconsistency in literature regarding the most effective vasodilatory medication or combination of medications. REVIEW OBJECTIVE The objective of this study is to identify the effectiveness of vasodilatory medications on radial artery spasm in patients undergoing transradial coronary artery procedures. INCLUSION CRITERIA TYPES OF PARTICIPANTS This review considered studies that included participants aged 18 years and over undergoing non-emergent transradial percutaneous coronary artery procedures. TYPES OF INTERVENTION(S) This review considered studies that used vasodilating intravenous and intra-arterial medications or combinations of medications prior to commencing and during transradial coronary approaches to reduce radial artery spasm. OUTCOMES The outcomes of interest were the incidence of radial artery spasm during percutaneous coronary procedure using objective and/or subjective measures and its effect on the successful completion of the procedure. TYPES OF STUDIES Randomized controlled trials published in the English language between 1989 to date were considered for inclusion. SEARCH STRATEGY The search strategy aimed to find both published and unpublished studies. A three-step search strategy was utilized in this review. An initial search of MEDLINE, CINAHL and Scopus was undertaken, followed by a search for unpublished studies. ASSESSMENT OF METHODOLOGICAL QUALITY Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical appraisal instruments. Any disagreements that arose between the reviewers were resolved through discussion. DATA EXTRACTION Quantitative data was extracted from papers included in the review using the standardized data extraction tool from RevMan5 (Copenhagen: The Nordic Cochrane Centre, Cochrane). DATA SYNTHESIS Quantitative data, where possible, was pooled in statistical meta-analysis using RevMan5. All results were subject to double data entry. Effect sizes expressed as risk ratio (for categorical data) and weighted mean differences (for continuous data) and their 95% confidence intervals were calculated for analysis. RESULTS Nine trials involving 3614 patients were included in the final review. Pooled data involving 992 patients on the effect of calcium channel blockers demonstrated a statistically significant reduction in the incidence of vasospasm in patients who received verapamil 5 mg compared to those who received a placebo (OR 0.33; 95%CI 0.19, 0.58). Similarly patients who received verapamil 2.5 mg or 1.25 mg had significantly fewer incidences of vasospasm when compared to those who received a placebo. Nitroglycerine 100mcg was demonstrated to be associated with a statistically significant reduction in the incidence of vasospasm. CONCLUSION The evidence demonstrates a benefit in the use of vasodilatory medications for the reduction of vasospasm in patients having radial coronary procedures. Further large-scale multi-center trials are needed to determine the preferred medication.

Abstract
Background. Orthotic intervention (splinting) may have become an end unto itself in the minds of therapists and clients rather than the means to enable optimal occupational performance. Some policy makers and payers seem to hold the belief that orthoses/splints are mere technical aids and as such do not require professional skill and expertise. Narratives. Three client stories demonstrate how iterative collaboration and follow-up help achieve client-identified objectives. Discussion. Client input is an important component of the process and an orthosis must fit into the person's lifestyle, especially if required for long-term use. Six essential considerations when providing orthoses to meet occupational goals are emphasized: client-centredness, comfort, cosmesis, convenience, less is more and follow-up. Use of the Canadian Occupational Performance Model for intervention planning and as an outcome measure is demonstrated. Practice Implications. Orthoses that are thoughtfully designed with client input and carefully constructed can make a difference in a person's life by relieving pain, providing protection and joint stabilization and enabling valued occupations.

Abstract
BACKGROUND Colonic spasm makes colonoscope advancement difficult. This prospective, randomized, double-blind, placebo-controlled study aimed to evaluate the efficacy of hyoscine-N-butylbromide as an antispasmodic during colonoscopy. METHOD Patients referred for elective colonoscopy were randomized into the study and placebo groups. Before the procedure, the study and placebo groups received 20 mg intra-venous hyoscine-N-butylbromide and intravenous saline solution of the same amount, respectively. Demographic and procedure--related data were recorded and compared between the groups. RESULTS Of 198 patients referred for elective colonoscopy, 121 were included (study group = 60, placebo group = 61). No differences were observed between the study and placebo groups in terms of demographic data, pre-procedure characteristics, and colonoscopic characteristics including the cecal intubation time, total procedure time, bowel preparation, sedation doses, hemo-dynamic findings, endoscopist satisfaction, patient comfort, and polyp detection rate. The only difference was an increase in the heart rate by 32% in the study group after hyoscine-N-butyl-bromide administration (p < 0.001). CONCLUSIONS Hyoscine-N-butylbromide did not reduce the time to reach the cecum and the total colonoscopy time, and patient and endoscopist satisfaction and polyp detection rate did not change. Furthermore, it was concluded that hyoscine-N-butylbromide can increase the risk of drug-related complications.

Abstract
OBJECTIVES The aim of this study is to review the available literature on the efficacy and safety of agents used for prevention of RAS. BACKGROUND Different vasodilator agents have been used to prevent radial artery spasm (RAS) in patients undergoing transradial cardiac catheterization. METHODS We included studies that evaluated any intra-arterial drug administered in the setting cardiac catheterization that was undertaken through the transradial access site (TRA). We also compared studies for secondary outcomes of major bleeding, procedure time, and procedure failure rate in setting of RAS prevention, patent hemostasis and radial artery occlusion. RESULTS 22 clinical studies met the inclusion criteria. For placebo, RAS rate was 12% (4 studies, 638 participants), which was similar to 2.5mg of verapamil 12% (3 studies, 768 participants) but greater than 5mg of verapamil (4%, 2 studies, 497 participants). For nicorandil, there was a much higher RAS rate compared to placebo (16%, 3 studies, 447 participants). The lowest rates of RAS was found for nitroglycerin at both 100 μg (4%) and 200 μg (2%) doses, isosorbide mononitrate (4%) and nicardipine (3%). We found no information regarding the procedure failure rates, patent hemostasis, and radial artery occlusion in these studies. CONCLUSIONS In this largest and up-to-date review on intra-arterial vasodilators use to reduce RAS, we have found that the verapamil at a dose of 5mg or verapamil in combination with nitroglycerine are the best combinations to reduce RAS.

Abstract
PURPOSE The detailed efficacy of intraluminal L-menthol for preventing colonic spasm is not known. The aim of this study was to evaluate the effectiveness of L-menthol in preventing colonic spasm during colonoscopy. METHODS We analyzed 65 patients (mean age: 71.7 years; 49 men and 16 women) who were administered 0.8% L-menthol (MINCLEA, Nihon Seiyaku, Tokyo, Japan) intraluminally for severe colonic spasm during colonoscopic examination at Kyoto Prefectural University of Medicine between February 2012 and May 2013. The efficacy of L-menthol was defined as the absence of colonic spasm during a period of 30 s, and its effect was evaluated at 30 s, 1 min, and 5 min after administration. Additionally, various characteristics of these patients were analyzed. Twenty-seven patients with severe colonic spasm were administered intraluminal water and assessed as controls. RESULTS L-Menthol was effective in preventing colonic spasms in 60.0%, 70.8%, and 46.5% of patients at 30 s, 1 min, and 5 min, respectively. In contrast, water was effective in 22.2%, 29.6%, and 48.1% of patients at 30 s, 1 min, and 5 min, respectively. There was a significant difference about the efficacy at 30 s and 1 min between L-menthol and water (P = 0.0009, P = 0.0006). CONCLUSIONS L-Menthol (0.8%) was effective in preventing colonic spasm during colonoscopic examination.

Abstract
The investigation objective was to estimate the role of nontraumatic anal sphincter (AS) stretching, as a leading factor of success in minimally invasive and/or plastic proctological interventions. One-centre randomized investigation was performed in 83 patients: In 22 of them the AS fissura was revealed (in 16), suprasphincteric fistula (in 3) and coexistent rectocele 2-3 Ap (according to POP-Q classification) with thinning of the AS anterior segment, the degree III hemorrhoids and anterior AS fissure presence. Ninety units of botulotoxin preparation (Disport) were injected between internal and external AS portions 5-15 days preoperatively. The treatment results without botulotoxin injection were compared retrospectively. After botulotoxin injection performance the AS spasm elimination was noted, leading to the pain subsiding promotion before and postoperatively in all the patients observed. The spasm elimination have permitted to escape the anal high fistula recurrence as a result of the mucosal flap shift after intraluminal closure of the fistula or because of the fistula intermuscular electrowelding "suture" rupture, also have guaranteed the plastic sutures on AS, even while the stage II-III rectocele presence, not depending of performance of its simultant surgica correction.

Abstract
OBJECTIVES The aim of this study was to compare the efficacy of nitroglycerin and diltiazem versus nitroglycerin alone in preventing radial artery spasm (RAS) during transradial coronary procedures. BACKGROUND Spasm after transradial access decreases procedural success. Multiple spasmolytics are used to prevent spasm. Individual efficacy of these agents is not conclusively established. METHODS One hundred and fifty patients undergoing coronary procedures through radial artery were enrolled and divided into two groups of 75 patients each. Patients in Group A received 200 μg nitroglycerin plus 2.5 mg diltiazem intra-arterially, and group B patients received 200 μg nitroglycerin plus placebo (saline). Blood pressure (BP) and heart rate (HR) were recorded at baseline and for 5 minutes after cocktail was given. Clinical signs of RAS, such as pain and resistance during catheter maneuver, were recorded in both groups during the procedure. RESULTS Systolic and diastolic BP decreased significantly in Group A compared to Group B after cocktail was given (P<.001 and P<.022, respectively). There were no significant changes of HR in either group. There was no significant difference in the incidence of clinical RAS between Group A (diltiazem plus nitroglycerin) versus Group B (nitroglycerin alone) (5% vs 7%; P=1.000). Furthermore, we found higher incidence of local burning pain in the forearm in patients that receive intra-arterial diltiazem plus nitroglycerin compared to nitroglycerin alone (21% vs 9%; P=.041). CONCLUSION Diltiazem plus nitroglycerin showed no advantage compared to nitroglycerin alone in prevention of RAS in transradial approach.

Abstract
Sensory afferent transmission and associated spinal reflexes are normally inhibited by serotonin (5-HT) derived from the brain stem. Spinal cord injury (SCI) that eliminates this 5-HT innervation leads to a disinhibition of sensory transmission and a consequent emergence of unusually long polysynaptic excitatory postsynaptic potentials (EPSPs) in motoneurons. These EPSPs play a critical role in triggering long polysynaptic reflexes (LPRs) that initiate muscles spasms. In the present study we examined which 5-HT receptors modulate the EPSPs and whether these receptors adapt to a loss of 5-HT after chronic spinal transection in rats. The EPSPs and associated LPRs recorded in vitro in spinal cords from chronic spinal rats were consistently inhibited by 5-HT(1B) or 5-HT(1F) receptor agonists, including zolmitriptan (5-HT(1B/1D/1F)) and LY344864 (5-HT(1F)), with a sigmoidal dose-response relation, from which we computed the 50% inhibition (EC(50)) and potency (-log EC(50)). The potencies of 5-HT receptor agonists were highly correlated with their binding affinity to 5-HT(1B) and 5-HT(1F) receptors, and not to other 5-HT receptors. Zolmitriptan also inhibited the LPRs and general muscle spasms recorded in vivo in the awake chronic spinal rat. The 5-HT(1B) receptor antagonists SB216641 and GR127935 and the inverse agonist SB224289 reduced the inhibition of LPRs by 5-HT(1B) agonists (zolmitriptan). However, when applied alone, SB224289, SB216641, and GR127935 had no effect on the LPRs, indicating that 5-HT(1B) receptors do not adapt to chronic injury, remaining silent, without constitutive activity. The reduction in EPSPs with zolmitriptan unmasked a large glycine-mediated inhibitory postsynaptic current (IPSC) after SCI. This IPSC and associated chloride current reversed at -73 mV, slightly below the resting membrane potential. Zolmitriptan did not change motoneuron properties. Our results demonstrate that 5-HT(1B/1F) agonists, such as zolmitriptan, can restore inhibition of sensory transmission after SCI without affecting general motoneuron function and thus may serve as a novel class of antispastic drugs.

Abstract
BACKGROUND children undergoing ureteroneocystostomy suffer from post-operative pain due to the surgical incision and bladder spasm. A single-shot caudal block is a common technique for paediatric analgesia, but a disadvantage is the limitation of a short duration in spite of the additives co-administered. A few clinical trials have shown that ketorolac provides an effective post-operative analgesia and reduces the bladder spasms after ureteral implantation in children. We compared the efficacy of a continuous infusion of ketorolac and fentanyl in post-operative analgesia and bladder spasm in children who underwent ureteroneocystostomy. METHODS fifty-two children were allocated to the ketorolac group (Group K, n=26) and fentanyl group (Group F, n=26). After general anaesthesia, a caudal block was performed with 1.5 ml/kg of 0.15% ropivacaine. At the beginning of surgery, an infusion was started after the bolus injection of ketorolac 0.5 mg/kg or fentanyl 1 microg/kg. An infusion device was programmed to deliver ketorolac 83.3 microg/kg/h or fentanyl 0.17 microg/kg/h for 48 h. RESULTS two of Group F and three of Group K were excluded from the study. Post-operative pain scores were similar between the two groups. One of Group K (4%) and seven of Group F (30.4%) experienced bladder spasms. The rescue analgesic requirements were significantly less in Group K. CONCLUSIONS a Continuous infusion of ketorolac provided effective analgesia after operation in children who underwent ureteroneocystostomy as well as a low dosage of fentanyl. Ketorolac was more effective in reducing the frequency of bladder spasms and rescue analgesic requirements.

Abstract
OBJECTIVES The aim of this study was to assess the impact of length and hydrophilic coating of the introducer sheath on radial artery spasm, radial artery occlusion, and local vascular complications in patients undergoing transradial coronary procedures. BACKGROUND Radial artery spasm is common during transradial procedures and the most common cause for procedural failure. METHODS We randomly assigned, in a factorial design, 790 patients scheduled for a transradial coronary procedure to long (23-cm) or short (13-cm) and hydrophilic-coated or uncoated introducer sheaths. The primary outcome measure was clinical evidence of radial artery spasm, and secondary outcome measures were patient discomfort and local vascular complications. RESULTS Procedural success was achieved in 96% of the cases, and radial artery spasm accounted for 17 of 33 failed cases. There was significantly less radial artery spasm (19.0% vs. 39.9%, odds ratio [OR]: 2.87; 95% confidence interval [CI]: 2.07 to 3.97, p < 0.001) and patient reported discomfort (15.1% vs. 28.5%, OR: 2.27; 95% CI: 1.59 to 3.23, p < 0.001) in patients receiving a hydrophilic-coated sheath. No difference was observed between long and short sheaths. Radial artery occlusion was observed in 9.5% of the patients and was not influenced by sheath length or coating. A local large hematoma or arterial dissection was seen in 2.6% of the patients with no difference in groups allocated at randomization. Younger age, female sex, diabetes, and lower body mass index were identified as independent predictors of radial artery spasm. CONCLUSIONS Hydrophilic sheath coating, but not sheath length, reduces the incidence of radial artery spasm during transradial coronary procedures.

Abstract
BACKGROUND/AIMS Colonoscopy has a significant miss rate for colorectal polyp screening. The present study hypothesized that reduced colonic spasm with antispasmodic agents might yield a better visual field to result in enhanced polyp detection rate. METHODOLOGY In a prospective, randomized, double-blind study design, muscle spasm was recorded during insertion and withdrawal during routine colonoscopy, and the number of polyps detected were compared between two groups of 58 patients characterized with either hyosine N-butyl bromide (Hyosine group) or placebo (Placebo group) injected at reaching the cecum. RESULTS The number of patients with decrease in spasm score of 0, 1, and 2 between insertion and withdrawal were 5 (8.6%), 31 (53.4%), and 22 (37.9%) in the Hyosine group, and 10 (17.2%), 46 (79.3%), and 2 (3.4%) in the Placebo group, respectively (p < 0.001). In patients with spasm score > or = 3 during insertion, more polyps per patient were likely to be detected in the Hyoscine group than the Placebo group (1.21 +/- 2.23 vs. 0.41 +/- 0.91; p = 0.060). CONCLUSIONS Our study suggests that hyosine might increase the detection rate of polyps in patients with moderate to marked degree of colonic spasm during colonoscope insertion. Further large scale studies are needed to validate our observations.

Abstract
Radial arterial access for coronary angiography is widely used in adults. We aimed to determine its safety and feasibility in pediatric practice. Twelve children and adolescents post cardiac transplantation (13 procedures) were studied. The radial artery was cannulated with a 5-Fr sheath after subcutaneous injection of 2% lidocaine. A mixture of verapamil, heparin, and isosorbide dinitrate was administered to reduce spasm. Selective coronary angiograms were obtained using Judkin or Amplatz coronary catheters. Following the procedure, hemostasis was achieved with a TR Band. Median age was 16.7 years (range, 12.1-18.8 years), and median weight 55.2 kg (range, 39-81 kg). Seventy percent of cases were under local anesthetic. Radial access was successful in 85%. Severe arterial spasm led to abandonment in one and failure to complete the study adequately in two patients. No vascular complications occurred. On direct questioning all but one patient preferred the radial approach. We conclude that the radial approach to coronary angiography is safe and feasible in children and adolescents. Radial artery spasm can be a problem and difficult to reverse once it occurs, leading to procedure abandonment. However, the technique is successful in the majority of cases and provides an alternative approach to arterial access in this age group.

Abstract
BACKGROUND For many headache types, occipital peripheral nerve stimulation (ONS) provides significant relief of chronic, frequent, and severe headaches. Though rarely reported, ONS may cause painful muscle spasms that make stimulator use impractical. The classic description of the technique advocates placement of the leads transversely at the level of the arch of C1 or at C1-2. At that level, the greater occipital nerve (GON) infrequently pierces the superficial fascia of the neck muscles to become superficial. However, important anatomic variability exists. OBJECTIVE To report placement of leads higher at the nuchal line rather than the classically recommended C1 level to avoid ONS-induced muscle spasm. METHODS Four interventional pain physicians independently revised ONS leads due to painful muscle stimulation. Five case reports of surgical ONS lead revision for management of ONS-induced muscle spasms are described and discussed. RESULTS Placement of peripheral neurostimulator leads at or above the nuchal line in these 5 cases provided good paresthesiae without causing neck muscle spasm. CONCLUSION Lead placement at the level of C1 or C1-2 may cause some patients to have intolerable neck/occipital spasm during neurostimulation. This is the first known published report of technical variation in the location of lead placement, at the nuchal line in a transverse fashion, for ONS. Placing ONS leads at the level of the occipital protuberance appears to eliminate ONS-induced muscle spasm while allowing good paresthesia coverage. LIMITATIONS Stimulation parameters vary, thus posting parameters may be misleading as muscle spasms occurred despite multiple reprogramming attempts and were a function of lead position, not program settings.

Abstract
OBJECTIVE Radio-cephalic arteriovenous fistulas (AVFs) have high early failure ratio. Increased sympathetic activity and spasm of radial artery during the surgery may responsible for early occlusion rate. DESIGN Fifty patients were randomized to two groups (each containing 25 patients). Stellate Ganglion Blockade (SGB) was performed in Group 1. Another group was considered as control group (Group 2) to make statistical comparisons. All AVFs were performed under local anesthesia in both groups. RESULTS Average fistula flow was 201.4+/-40.4 ml/min in Group 1 and 155.6+/-27.4 ml/min in Group 2 (p < 0.001). While average peak velocity of radial artery was 167.1+/-31.3 cm/sec in Group 1, it was 107.8+/-15.8 cm/sec in Group 2 (p < 0.001). Thrill was found in all Group 1 patients, but there was thrill only 13 of the Group 2 patients (p < 0.001). Mean maturation time was 41.4+/-6.8 days after surgery in Group 1 and 77.1+/-10.5 days in Group 2 (p < 0.001). Adequate vascular access was obtained 19 patients in Group 1 and 12 patients in Group 2 (p = 0.041). CONCLUSION AVF occlusion rate is much more common in early postoperative period. Diminished sympathetic tonus by preemptive SGB not only increases early patency rate but also increases fistula maturation rate.

Abstract
BACKGROUND For management of postoperative bladder spasm by the ureteral reimplantation, general anesthesia and epidural anesthesia are selected in many hospitals, but epidural anesthesia is not a common technique for various complications and risks. We examined whether postoperative bladder spasms can be prevented by general anesthesia combined with single shot caudal anesthesia. METHODS We studied 18 patients undergoing ureteral reimplantation. Premedicated by diazepam syrup (0.5 mg x kg(-1), maximum dose 10 mg). In combination with caudal anesthesia with 0.3% ropivacaine (3 mg x kg(-1), maximum dose 60 mg), general anesthesia was maintained with oxygen, nitrous oxide and sevoflurane. For the evaluation of pain relief we used face pain scale when the patients returned to the ward, postoperative 5 hours, 24 hours and at discharge. RESULTS At postoperative 5 and 24 hours, some patients had a pain scale of above 3. But, those under pain scale 1 was 83%. At discharge, all patients were evaluated as pain scale 0 or 1. CONCLUSIONS General anesthesia combined with single shot caudal anesthesia suppressed postoperative bladder spasm. All patients were discharged within 3 postoperative days.

Abstract
BACKGROUND Tetanus is a life threatening disease. Reported mortality for tetanus is 15-39%. Conventional treatment includes heavy sedation and artificial ventilation. Complications resulting from long term heavy sedation and artificial ventilation contribute to 60% of the total mortality caused by tetanus. In this study magnesium sulphate was used to reduce the need for sedation and artificial ventilation. Objectives of this prospective study were to determine the role of magnesium sulphate in post traumatic tetanus. METHODS The study was carried out in surgical Intensive Care at Pakistan Institute of Medical Sciences (PIMS), Islamabad from Jan 2004 to Dec 2007. Forty-four patients presented during this period and 33 patients were included in the study. All patients had tracheostomy done within 48 hours. Every patient was started Magnesium Sulphate therapy for control of spasms after sending baseline investigations. Patients were given ventilatory support when needed. All data was entered in well structured proforma. SPSS-10 was used to analyse data. RESULTS Thirty-three patients were included in the study and all patients were given magnesium sulphate. Out of these, 45.5% cases were grade 4 tetanus, 73.6% and 63.3% cases did not require artificial ventilation and additional sedation respectively, 51.1% patients remained free of complications of tetanus. Overall mortality was 30.3%. CONCLUSIONS Use of Magnesium Sulphate is safe and reduces the need for sedation and artificial ventilation in high grade tetanus thus contributing to survival benefit in adult post-traumatic tetanus cases.

Abstract
OBJECTIVE To assess different approaches to the dental management of lip injuries caused by self-inflicted oral trauma in 7 patients. METHOD AND MATERIALS The patients were grouped based on 3 treatment approaches: group 1, placement of an oral appliance; group 2, botulinum toxin type A neuromuscular block; and group 3, oral surgery. RESULTS AND CONCLUSION Neuromuscular block can be the first choice of treatment for patients with self-injurious behavior since botulinum toxin A injection is a well-tolerated, safe, and effective procedure, permitting improvement in muscle spasticity, bruxism, range of mouth opening, oral hygiene, and lip trauma. The second option would be the use of the oral appliance, and the last choice is oral surgery. Laser therapy was also found to be effective when applied to traumatic injuries in patients who present self-inflicted oral trauma.

Abstract
BACKGROUND Radial artery spasm is one of the most common complications during coronary angiography via the transradial approach, causing patient discomfort or sometimes interrupting the procedure. This study was designed to compare the spasmolytic effect between nicorandil and a cocktail during transradial coronary angiography. METHODS A randomized study to compare 4 mg of nicorandil and a cocktail (mixture of normal saline, 200 microg of verapamil) was performed in 150 patients. We examined vasospasms of the radial artery that were expressed as stenosis of the radial artery vessel diameter after the procedure. RESULT The reductions of systolic and diastolic blood pressures showed no significant differences between the two groups (15.4+/-11.5/7.7+/-7.8 mmHg for nicorandil and 16.3+/-13.4/6.2 mmHg for cocktail). Both agents induced a significant radial artery vasodilation after transradial administration at proximal and mid segments (P < 0.001 for all). Nicorandil showed a significant increase of the mean change of the radial artery diameter compared to the cocktail at mid-segment (0.32+/-0.23 mm for nicorandil and 0.24+/-0.15 mm for a cocktail, P < 0.05). There was no statistically significant difference between the two groups in radial artery spasm (50.7% vs. 52.0% in nicorandil and a cocktail, respectively) after catheterization. CONCLUSION Nicorandil with vasodilator effects by a dual mechanism was effective as the cocktail in preventing radial artery spasm during transradial coronary angiography.

Abstract
OBJECTIVE Radial artery pedicle tissue cooling during harvesting is one of the major causes of vasospasm. We aimed to compare the effects of the pedicle rewarming method, normothermic organ bath, and one of the most preferred topical antispasmodic agents, verapamil-nitroglycerin solution alone or in combination on the blood flow of radial artery. METHODS Consecutively randomized patients (n=80) undergoing coronary bypass were organized as four equal-sized groups. Effects of normothermic organ bath and topically performed verapamil-nitroglycerin solution alone or in combination on the blood flow of radial artery were investigated. In the control group no antispasmodic treatment was performed. Free flows were measured at three stages: as initial flow after minimal distal harvesting, post-harvesting flow after total harvesting, and post-treatment flow following a waiting period after the application of the antispasmodic protocol. At each stage, pedicle and esophageal temperatures were also recorded. RESULTS Radial artery pedicle temperatures decreased significantly during harvesting in all groups (p<0.001). Normothermic organ bath, topical verapamil-nitroglycerin solution treatment, and their combination increased flow significantly (p<0.001, from 40.3+/-10.48 ml/min to 64.3+/-18.8 ml/min, from 38.9+/-13.91 ml/min to 62.75+/-15.23 ml/min, from 41.4+/-11.19 ml/min to 75.4+/-15.32 ml/min, respectively). The differences between the initial and post-treatment flows were not significant in the combined procedure group (p>0.05), whereas the initial levels were not reached in the post-treatment flows (p<0.05) in the normothermic organ bath and verapamil-nitroglycerin groups. CONCLUSIONS Hypothermia plays an important role in radial artery vasospasm. Normothermic organ bath and verapamil-nitroglycerin solution alone or in combination relieve spasm of radial artery.

Abstract
OBJECTIVE This study is planned bringing about a new choice for the prophylaxis of RA spasm which is topical iloprost and compares its efficacy with papaverine and diltiazem. DESIGN Twenty eight CABG patients with RA grafts were categorized into four groups by taking into account the topical vasodilator (papaverine, diltiazem, iloprost and saline) that was utilized during harvesting. Arterial segments were separated into four rings and were than soaked with KCL, norepinephrine, phenylephrine and serotonin. Then, acetylcholine was given to induce relaxation and the preparations were put to rest for 10 minute. RESULTS The contraction response achieved by the vasoreactive agents was most effectively inhibited by papaverine. The effectiveness of the response obtained by iloprost was similar to that of papaverine and significantly stronger than that of diltiazem. Especially at high vasoreactive substance concentrations, diltiazem had a contraction close to that of the control while the protective effect was weaker than those of papaverine and iloprost. CONCLUSION Iloprost can be recommended as a strong alternative to the topical agents used for preventing arterial graft spasm.

Abstract
OBJECTIVE To assess the incidence of pharyngoesophageal spasm and the results of its prevention. PATIENTS AND METHODS This a prospective longitudinal study including two groups of patients: a study group - 69 laryngectomees to undergo spasm prevention surgery, and a control group - 52 laryngectomees. The diagnostic methods used were: esophageal test, double contrast roentgenoscopy; surgical methods: neurectomy of pharyngeal plexus, myotomy of pharyngeal constrictors, no-muscle layer closure of the pharyngeal defect with myotomy of the esophageal entrance. RESULTS The incidence of pharyngoesophageal spasm in the control and study group was 34.62% and 14.5%, respectively. In the control group the spasm was significantly more common in patients older that 56 years. This correlation was not observed in the study group. CONCLUSION A great number of laryngectomees, mainly elderly persons, suffer from voice limiting pharyngoesophageal spasm which correlates to poor rehabilitation results in elderly. Pharyngoesophageal spasm preventing procedures are more beneficial in the elderly.

Abstract
PURPOSE Premedication with glucagon or hyoscyamine is reported to be effective in reducing colonic spasm. However, these drugs can be associated with unfavorable events. This prospective study was designed to compare the effects of premedication with glucagon with those of scopolamine butylbromide on cardiopulmonary parameters, intubation time, and patient discomfort in unsedated patients undergoing diagnostic colonoscopy. METHODS One hundred consecutive adult patients (65 males) undergoing colonoscopy without sedation were randomized to receive 1 mg of glucagon (n = 50) or 20 mg of scopolamine butylbromide (n = 50), intramuscularly. Physiologic changes, including systolic blood pressure, heart rate, and oxygen saturation, were monitored before colonoscope insertion and at three-minute intervals during colonoscopy. The percentages of completed procedure and time to cecal intubation were recorded. Patients were asked to rate pain by using a five-point pain score (0 = no pain; 4 = severe pain). RESULTS The percentages of completed procedure (96 vs. 98 percent), time to cecal intubation (16.3 vs. 14.5 minutes), and pain score (1.7 vs. 1.5) did not differ significantly between two groups. An increase in heart rate of more than ten beats per minute from baseline during colonoscopy occurred significantly more often in scopolamine group (44 percent of 50 patients) than in the glucagon group (12 percent of 50 patients; P = 0.0004). There were no significant differences between the two study groups with regard to changes in systolic blood pressure and decrease in oxygen saturation during colonoscopy. CONCLUSIONS Premedication with 1 mg of glucagon facilitates favorable examination with respect to physiologic changes compared with 20 mg of scopolamine. These features favor glucagon as the preferred premedication for patients undergoing colonoscopy.

Abstract
Uterine artery vasospasm can complicate uterine artery embolization (UAE) by prolonging procedure times or even causing treatment failure. Embolization must be delayed until the spasm improves and adequate antegrade flow in the vessel is restored. Vasospasm can also produce a "false endpoint" to the procedure, where stasis of flow in the vessel is falsely attributed to successful embolization but is actually the result of vasospasm, leading to undertreatment or treatment failure. Traditional treatments for uterine artery vasospasm have included transcatheter intra-arterial vasodilators and catheter withdrawal from the vessel, both of which can yield mixed results. We report a case of uterine artery vasospasm during UAE successfully treated with transdermal nitroglycerine ointment.

Abstract
BACKGROUND AND AIM Intraluminally administered peppermint oil (PO) is reportedly a safe and useful antispasmodic for gastroscopy, colonoscopy and double-contrast barium enema. The aim of this study was to examine the efficacy of oral PO for double-contrast barium meal examination (DCBM) without other antispasmodics. METHODS Two hundred and five randomly chosen subjects (PO group) and 215 sex- and age-matched controls were enrolled. All participants underwent DCBM. The PO group was orally administered PO and a barium suspension mixture at the start of DCBM. Radiographs were blindly evaluated for spasm and overlapping with barium-filled duodenal loops (scored 0-3, indicating none to severe). The quality of barium coating of the mucosa and overall diagnostic quality (scored 0-3, indicating not acceptable to excellent) were also evaluated. RESULTS There was no significant difference in subject acceptance between PO group and controls, and no adverse effects in either group. Scores for spasm at the esophagus, lower stomach and duodenal bulb were significantly lower in the PO than in the control group (P < 0.001). Scores for overlapping at the lower stomach and duodenal bulb were significantly lower in the PO than in the control group (P < 0.05, P < 0.01, respectively). Scores for overall diagnostic quality at the esophagus, lower stomach and duodenal bulb were significantly higher in the PO than in the control group (P < 0.001). Oral PO reduces spasm of the esophagus, lower stomach and duodenal bulb, inhibits barium flow to the distal duodenum, and improves diagnostic quality without other antispasmodics. CONCLUSIONS Oral PO is a safe, easy to use and effective antispasmodic for DCBM.

Abstract
BACKGROUND Very little is published about the symptom profile of children with life-limiting illnesses other than cancer. METHOD A postal questionnaire was sent to children's hospice staff who were asked to identify symptoms experienced by life-limited children which caused them anxiety. RESULTS Staff in 23 hospices were sent questionnaires. Twenty-eight questionnaires were returned from 10 doctors and 18 nurses. Just under half of the hospices contacted were represented. The staff were very experienced but had significant anxieties about treating some of their patients. AIMS This study aimed to identify the symptoms which cause anxiety to staff working in children's hospices. More than 70% of all staff groups felt that identifying the symptom correctly caused more anxiety than treating identified symptoms. For doctors the top five symptom problems were, seizure control, spasms, pain assessment, unidentified distress and vomiting. For nurses the main concerns were the non-verbal child in distress, psychiatric or psychological problems, assessing pain, seizures, pain management, vomiting. CONCLUSIONS Doctors and nurses perceive seizures, pain management, and vomiting as the most troublesome symptoms for children with life-limiting conditions. Further research is needed into symptom management in this area.

Abstract
Radial artery spasm occurs frequently during the transradial approach for coronary catheterization. Premedications with nitroglycerin and verapamil have been documented to be effective in preventing radial spasms. Verapamil is relatively contraindicated for some patients with left ventricular dysfunction, hypotension and bradycardia. We would like to know whether nitroglycerin alone is sufficient for the prevention of radial artery spasm. We conducted a randomized controlled trial to compare the spasmolytic effect between heparin alone, heparin plus nitroglycerin and heparin plus nitroglycerin and varapamil during transradial cardiac catheterization. In this study, a total of 406 patients underwent transradial cardiac catheterization and intervention. After successful cannulation and sheath insertion of radial arteries, 133 patients in group A received 3,000 units of heparin, 100 microg of nitroglycerin and 1.25 mg of verapamil via sheath, 135 patients in group B received 3,000 units of heparin and 100 microg of nitroglycerin, and 93 patients in group C received 3,000 units of heparin. Five patients in group A (3.8%), 6 patients in group B (4.4%) and 19 patients in group C (20.4%) showed radial spasms. There is no statistically significant difference between groups A and B (p = 0.804), but there are strong statistically significant differences between groups A and C (p = 0.001) and groups B and C (p = 0.003). Intra-arterial premedication with 100 microg nitroglycerin and 3,000 units of heparin is effective in preventing radial spasms during transradial cardiac catheterization.

Abstract
OBJECTIVE To investigate the etiology and treatment of bladder spasm associated with benign prostatic hyperplasia (BPH). METHODS Urodynamic tests were performed in 102 cases of BPH before operation. The correlation of bladder spasm with aging, international prostate symptom score (IPSS), quality of life, prostatic volume, operation methods and urodynamic indexes was studied by t and chi2 tests. RESULTS The incidences of bladder spasm in the lower compliant bladder and unstable bladder were 32.1% (9/28) and 42.5% (13/20), and those after suprapubic prostatectomy and transurethral resection of the prostate (TURP) were 50.9% (26/51) and 23.3% (12/51). There was significant difference between operation methods (P < 0.05). CONCLUSION Bladder spasm easily develops in the lower compliant bladder and unstable bladder, especially after suprapubic prostatectomy. TURP might decrease the incidence of bladder spasm after BPH operation.

Abstract
Cyanotic breath-holding spell is a benign and self-limiting disease of young children but occasionally associated with sudden, unexpected death. The authors report a rare case in a 2-year-old girl with a severe form that started after radical resection of a cervicomedullary ganglioglioma. She was admitted to our hospital because of delayed and unstable gait. Since magnetic resonance imaging showed a cervicomedullary tumor, she underwent a radical resection and histology showed the tumor to be a ganglioglioma. Postoperatively, the function of the lower cranial nerves and cerebellum deteriorated and hemiparesis on the left became apparent, but she returned to the preoperative state in a few months. In addition, mild sleep apnea (Ondine curse) and severe cyanotic breath-holding spells occurred. The former responded to medication but the latter failed and continued several times per day with a rapid onset and progression of hypoxemia, loss of consciousness, sweating and opisthotonos. Five months after the operation, the patient returned home with a portable oxygen saturation monitor equipped with an alarm. This case indicates that cyanotic breath-holding spell, as well as sleep apnea, is critical during the early postoperative period. This is the first report observing that such spells may occur as a complication of radical resection of a cervicomedullary tumor.

Abstract
BACKGROUND Radial artery grafts are used for coronary artery bypass grafting (CABG), and postoperative antispasm therapy with diltiazem is performed widely. Some investigators have warned that diltiazem administration after cardiac surgery is harmful to renal function. We designed a retrospective study to investigate the renal and hemodynamic effects of the postoperative administration of diltiazem in patients undergoing CABG. METHODS Subjects were 90 consecutive CABG patients. All were treated with diltiazem during surgery (a 0.1 mg/kg bolus injection followed by continuous infusion at 2 microg x kg(-1) x min(-1)). In the 50 patients (diltiazem group) with a radial artery graft, intravenous diltiazem administration was continued until the oral intake of diltiazem (90 mg/d) was begun to avoid graft spasms. In the remaining 40 patients without a radial artery graft, diltiazem was not continued postoperatively (control group). Postoperative renal function, assessed by serum creatinine level and creatinine clearance, and hemodynamic variables (heart rate, arterial pressure, pulmonary wedge pressure, cardiac index, left ventricular stroke work index) was compared between the two groups. RESULTS Renal function: Serum creatinine concentrations on postoperative days 1 through 7 were lower, and the endogenous creatinine clearance in the early postoperative period was higher in diltiazem group than in control group, although the differences were not significant. Hemodynamics: Heart rate was lower in diltiazem group than in the control group, but blood pressure, pulmonary wedge pressure, cardiac index, left ventricular stroke work index, and urinary output were similar between the groups. CONCLUSIONS Our results confirmed that intravenous diltiazem treatment in patients undergoing CABG is not harmful to renal function.

Abstract
Classic instrument design does not always match the physical capacity of the musician, as instruments are often chosen because of the pleasing sound and not the ease of play. Devices that are commercially available to create a more ergonomic structure may not address the specific needs of a musician with a chronic condition. Through basic splinting of the musician with an injury, these physical stressors can be reduced, allowing the continuation of musical practice and performance. Appropriate design modification requires a solid understanding of upper extremity anatomy, splint design technique, and the biomechanic principles of playing the instrument. Through knowledge of music theory and appreciation, one may modify the instrument while protecting tonal flexibility, resonance, mechanical freedom, and sound quality. Two case studies present a range of splint design, from small to large, static to dynamic, and for congenital or chronic conditions.
