RESUMO
Background and Objectives: This study aimed to determine the effects of tourniquet use and the complications of total knee arthroplasty (TKA) in patients without comorbidities to investigate whether tourniquet application can be employed without adverse effects and to assess its impact on the occurrence of any complications. Materials and Methods: A total of 106 patients who underwent unilateral TKA were divided randomly into two groups according to whether a tourniquet was used during the surgery or not. Patients with comorbidities (except arterial hypertension) were excluded from the study. Knee Injury and Osteoarthritis Outcome Score, joint range of motion, visual analog scale (VAS) score, total blood loss during and after surgery, postoperative analgesic consumption, and side effects were the main factors evaluated in the study. Results: In the tourniquet group, where the VAS scores were higher, the use of analgesics was also significantly higher. While there was no statistically significant difference in total blood loss between the tourniquet and non-tourniquet groups, the postoperative and occult blood losses were higher in the tourniquet group. The differences between the two groups in all other parameters were very small and not statistically significant. Conclusions: The findings of the current study suggest that when the comorbidities of patients are thoroughly documented and clarified prior to surgery, tourniquets should be applied selectively to individuals without any pre-existing health conditions.

BACKGROUND: Shoulder dislocation, particularly anterior dislocation, is a common orthopedic injury often presenting in emergency care settings, characterized by significant pain and muscle spasms. Prompt reduction is essential to alleviate symptoms and restore function. The Cunningham technique employs gentle pulling and massage motions targeted at the muscles and has emerged as a promising method for reducing anterior shoulder dislocations. However, its reported success rates vary widely across studies, and questions remain regarding its efficacy, particularly in cases of failure. This study aims to evaluate the effectiveness of the Cunningham technique for reducing anterior shoulder dislocations and its potential role in providing analgesia and muscle relaxation as an adjunctive method. METHODS: A retrospective study was conducted on patients presenting with acute anterior shoulder dislocation at a single center. Reduction using the Cunningham technique was performed initially, followed by the external rotation technique if unsuccessful. Procedural sedation and analgesia were administered if the reduction was still not achieved, and shoulder dislocation reduction was performed again through the external rotation method. The patients' VAS scores were recorded and evaluated the Cunningham technique's effectiveness in reduction and whether it increases the effectiveness of other techniques applied for reduction by lowering the VAS score, even in cases where it is not effective. RESULTS: A total of 61 patients were included in the study. The reduction was performed using the Cunningham technique in 34.4% (21/61) patients, the external rotation technique in 47.5% (29/61) patients, and the external rotation technique with PSA in 18% (11/61) patients. Significant differences were observed in the duration of hospital stay among the three techniques, with ER with PSA resulting in the longest stay. VAS scores showed significant improvements from initial presentation to post-reduction in all three groups. A significant decrease in pre-reduction VAS scores was observed during the transition from the Cunningham technique to other techniques. CONCLUSION: The Cunningham technique showed effectiveness in reducing anterior shoulder dislocations, providing analgesia, and muscle relaxation. It demonstrated favorable outcomes as an initial reduction technique, with the external rotation technique used as a subsequent option. Further studies comparing the success rates and complications of the Cunningham technique with other reduction methods are warranted to establish its role in clinical practice.

Close association has been established between obstructive sleep apnea (OSA) and adolescent idiopathic scoliosis (AIS), with PSQ being employed as a screening method for OSA. A cross-sectional study was conducted among patients aged from 10 to 16 years who presented to a scoliosis outpatient clinic. Patient demographics, radiological assessments, and PSQ scores were gathered. A total of 299 patients were included in the study, with 28.7% males and 71.2% females. The average Cobb angle was 6.20°. PSQ scores revealed a prevalence of 33.4% for significant obstructive sleep apnea. Patients diagnosed with AIS exhibited a prevalence of 32.9% with positive PSQ results. Among those undergoing adenoid and/or tonsil surgery, 27% had positive PSQ scores. Factors such as genetics, abnormal biomechanical forces, environmental factors including melatonin, and intermittent hypoxia were explored for their potential contribution to AIS etiology. The aim of the study is to underscore the importance of early detection and intervention in OSA cases and highlights the effectiveness of the PSQ, as a screening tool in identifying sleep disorders. The findings underscore the complex relationship between OSA and AIS, and moreover any spinal curvature is in relation with OSA.
RESUMO
Introduction Scoliosis, a multifaceted spinal deformity commonly affecting pediatric and adolescent populations, has spurred extensive scientific inquiry to understand its origins and impacts. Early-onset scoliosis (EOS), characterized by spinal curvature exceeding 10° before the age of 10, presents a unique challenge necessitating a comprehensive understanding of its etiological factors. Within this context, the potential role of hypoxia-induced by adenoid hypertrophy in contributing to the pathogenesis of EOS has emerged as an intriguing avenue of investigation. Materials and methods This retrospective study was conducted focusing on radiological and clinical data pertaining to children below 10 years of age who underwent isolated adenoidectomy for adenoid hypertrophy. Preoperative posteroanterior standing chest radiographs were utilized for scoliosis assessment, with Cobb angles serving as the primary measurement metric. To ensure accuracy and reliability, Cobb angle measurements were independently performed by two experienced observers. Statistical analyses encompassed the Mann-Whitney U test, Spearman correlation analysis, and intraclass correlation coefficient calculations to evaluate interobserver agreement. Results Among the cohort of 218 pediatric adenoidectomy patients, 177 individuals had radiographs suitable for EOS evaluation. The mean age of the participants was 5.72±2 years, with a nearly equal distribution of 52.5% male and 47.5% female patients. Strikingly, the study identified a 10.2% prevalence of coronal plane curvatures exceeding the critical threshold of 10°, indicative of EOS. The robust interobserver reliability was demonstrated by a commendable mean interclass correlation coefficient (ICC) value of 0.926, affirming consistent and accurate Cobb angle measurements between the observers. Conclusion In light of the heightened prevalence of EOS observed in children undergoing adenoidectomy, this study provides a compelling impetus for exploring the potential interrelationship between adenoid hypertrophy, hypoxia, and the emergence of early-onset scoliosis. The study underscores the importance of prospective research to elucidate the complex mechanisms connecting these factors, offering insights into potential risk factors and underlying pathogenic pathways associated with the development of early-onset scoliosis.
RESUMO
Oral ketamine has been found to be effective during invasive procedures in children with malignancy. To the best of our knowledge, analgesic effects of oral ketamine have not been reported in pediatric cancer pain management. We described a patient with end-stage cancer pain that was resistant to opioids and was relieved by oral ketamine.

Neurolytic celiac plexus block has been used successfully in the treatment of patients with intractable intra-abdominal pain due to malignancy or to benign pain syndromes. A new technique is described here for blocking the celiac plexus through the retrocrural approach with a special long stylet needle inserted under fluoroscopic guidance. Celiac blocks were performed in 2 groups of patients. In the first group (n=7), the classic technique was performed with the use of 2 needles; in the second group (n=5), 1 needle and 2 stylets were used to complete the block through the long guided needle approach. Parameters evaluated in each group consisted of the number of attempts, defined as the number of skin punctures, and fluoroscopy injection time, defined as time from the beginning of fluoroscopy to completion of successful needle insertion into the celiac area. Patients who had abdominal pain resulting from pancreatic cancer underwent celiac plexus block performed by the long guided needle technique. In the classic technique group, fluoroscopy injection time was 13+/-3 min and the number of attempts was 5.3+/-3; values in the long guided needle group were 8.9+/-3 min and 4.9+/-2, respectively. The difference in fluoroscopy injection times was significant (P<.05). The long guided needle technique for celiac plexus block may be an effective and appropriate method for beginners or for practitioners who are not knowledgeable about imaging techniques used in various medical specialties.

The aim of this retrospective study is to evaluate the upper and the lower extremity amputations with regard to phantom pain, phantom sensation and stump pain. A questionnaire consisting of 23 questions was send to the patients who underwent upper or lower extremity amputation surgery between 1996- 2005. The patients were questioned for the presence of phantom pain and sensations and if they existed for the frequency, intensity, cause of amputation, pre-amputation pain, stump pain, usage of artificial limb. Totally 147 patients were included and the response rate was 70 %. The incidence of phantom pain in Upper Extremity Group was 60 % and 65.8% in Lower Extremity Group. The incidence of phantom sensations was 70.7% in Upper Extremity Group and 75.6% in Lower Extremity Group. There was no significant difference between two groups considering in phantom pain and phantom sensations. The phantom pain was significantly higher in patients who lost dominant hand, experienced pre amputation pain and suffered stump pain. There were no significant differences in regard to phantom pain and sensation between upper and lower extremity amputations. However the presence of preamputation pain, stump pain and amputation of dominant hand were found as risk factors for the development of phantom pain.

OBJECTIVES: We evaluated the results of triple arthrodesis in rigid foot deformities and assessed the effect of internal fixation on clinical and radiographic results. METHODS: Thirty feet of 26 patients (12 females, 14 males; mean age 27 years; range 13 to 55 years) were treated with classic triple arthrodesis. Ten patients (12 feet) underwent temporary internal fixation with one or more Kirschner wires. Clinical evaluations were made with the use of both AOFAS (American Orthopaedic Foot and Ankle Society) and Angus-Cowell ankle-hindfoot scoring systems. Anteroposterior and lateral talocalcaneal and talus-first metatarsal angles were used as radiographic parameters. The mean follow-up period was 80.3 months (range 30 to 140 months). RESULTS: The mean AOFAS score increased from a preoperative 39.3 (range 16 to 59) to postoperative 90.8 (range 71 to 94). According to the Angus-Cowell criteria, the results were good in 19 feet (63.3%), fair in eight feet (26.7%), and poor in three feet (10%). Clinical improvement was statistically significant according to both scoring systems (p<0.05). Radiographically, all the angular values were within normal limits both in the early postoperative period and at the last follow-up (p<0.05). Pseudoarthrosis was detected in four feet (13.3%) and degeneration of the ankle and naviculocuneiform joints was detected in 12 feet (40%) and 17 feet (56.7%), respectively. Internal fixation had no significant effect on pseudoarthrosis, residual or recurrent deformity, and the degree of degeneration (p>0.05). CONCLUSION: Triple arthrodesis is a good alternative for functional and cosmetic improvement in foot deformities. Although internal fixation seems to have no significant effect, the use of a temporary fixation material may contribute to maintenance of reduction and surface contact.

STUDY OBJECTIVES: To investigate the effects of different doses of oral caffeine-paracetamol combinations in postdural puncture headache (PDPH) prophylaxis. DESIGN: Prospective, randomized, placebo-controlled, blinded study. SETTING: University hospital. PATIENTS: A total of 210 ASA physical status I and II patients undergoing lower extremity surgery. INTERVENTIONS: Patients were randomly divided into 3 groups. One hour before the spinal anesthesia, the first group (n = 70) received placebo, the second group (n = 70) received 500-mg paracetamol + 75-mg caffeine, and the third group (n = 70) received 500-mg paracetamol + 125-mg caffeine orally. The same doses were repeated every 6 hours for 3 days. Patients were then interviewed on days 1, 2, 3, 4, and 7 to inquire about any PDPH. The interviewer was unaware of the PDPH prophylaxis group members. Patients who were discharged early were interviewed by telephone. MEASUREMENTS AND MAIN RESULTS: Postdural puncture headache occurred in 11 patients (15.7%) in group 1, 10 patients (% 14.28) in group 2, and 10 patients (% 14.28) in group 3. The differences between the groups were insignificant (P > .05). The complications due to spinal anesthesia were similar in the 3 groups. Side effects of caffeine such as lack of sleep, tachycardia, and hypertension were not observed in groups 2 or 3. CONCLUSIONS: Prophylactic administration of paracetamol-caffeine combinations at the stated doses does not prevent PDPH.

BACKGROUND/AIM: Premature infants experience more respiratory problems after surgical procedures. We aimed to compare general anesthesia with sedation regarding the need for postoperative mechanical ventilation in infants undergoing retinopathy of prematurity (ROP) surgery. MATERIALS AND METHODS: Sixty patients who underwent laser surgery for ROP were included in this study. This study was performed between October 2010 and December 2012. The sedation group (Group S, n = 30) received 1 mg/kg ketamine and 1 mg/kg propofol as a bolus for induction. The patients then received an infusion of 100-150 µg kg(-1) min(-1) propofol and 0.25 mg kg(-1) h(-1) ketamine for maintenance. In the general anesthesia group (Group G, n = 30), anesthesia was induced using 8% sevoflurane by inhalation with 50% nitrous oxide in oxygen. Anesthesia was maintained with sevoflurane (2%) and 50% nitrous oxide in oxygen. RESULTS: There was no difference in gestational age, birth weight, current age, or current body weight between the two groups. Preoperative medical histories of the groups were similar. Two patients in Group S and 11 patients in Group G required postoperative mechanical ventilation (P = 0.010). Blood pressures and heart rates were similar. CONCLUSION: In premature infants, sedoanalgesia administration reduced the need for postoperative mechanical ventilation after surgery for ROP.

Human hydatid cyst is a zoonotic infection that usually attacks visceral organs. Primary soft tissue involvement is very rare, causing a diagnostic challenge. Primary soft tissue hydatid cyst was encountered in an 83-year-old man, which presented as a giant lesion in the posterior aspect of the right thigh, extending from the gluteal region proximally to the popliteal region distally. A multiloculated cystic mass was completely resected and histopathological examination confirmed the preoperative diagnosis. No local or systemic complications occurred postoperatively. The patient recovered fully at the end of postoperative 12 months.

BACKGROUND: Intrathecal α2 agonists prolong the duration of action of local anesthetics and reduce the required dose. Dexmedetomidine is an α2 receptor agonist and its α2/α1 selectivity is 8 times higher than that of clonidine. AIMS: In this study, we aimed to investigate the effect of adding dexmedetomidine to intrathecal levobupivacaine on the onset time and duration of motor and sensory blocks. STUDY DESIGN: Randomized controlled study. METHODS: Patients were randomly assigned into two groups. Group L (n= 30) patients received 3 mL (15 mg) of 0.5% levobupivacaine +0.3 mL normal saline and Group LD (n= 30) patients received 3 mL (15 mg) of 0.5% levobupivacaine + 0.3 mL (3 µg) dexmedetomidine. Sensory block onset time, block reaching time to T10 dermatome, the most elevated dermatome level, two dermatome regression time, sensory block complete regression time as well as motor block onset time, reaching Bromage 3 and regressing to Bromage 0 were recorded. RESULTS: Sensory and motor block onset times were shorter in Group LD than in Group L (p<0.001). The regression of the sensory block to S1 dermatome and Bromage 0 were longer in Group LD than Group L (p<0.001). The two dermatome regression time was longer in Group LD than Group L (p< 0.001). There were no statistically significant differences between groups in blood pressure and heart rate. There was no statistically significant difference between groups when adverse effects were compared. CONCLUSION: We conclude that intrathecal dexmedetomidine addition to levobupivacaine for spinal anaesthesia shortens sensory and motor block onset time and prolongs block duration without any significant adverse effects.

BACKGROUND: Intraoperative penile erections following the initiation of either regional or general anaesthesia is rare; however, when it occurs in patients undergoing urologic procedures it may delay, or even cancel the planned surgery. The aetiology is unclear. Various treatments proposed for producing detumescence are not always effective. Use of intracavernous alpha-adrenergic agonists is an efficient and rapid but short-lasting treatment. Furthermore, repeated intracavernous injections of vasoactive drugs may be harmful. Dexmedetomidine is a potent, selective α(2)-adrenoreceptor agonist. In our study, we evaluated the effect of dexmedetomidine on intraoperative penile erection. METHODS: Penile erection developed during an endoscopic procedure in 12 more than 7,800 patients. Anaesthesia used was general in 3 patients, epidural in 1 patient and spinal in 8 patients. The erection rigidity was evaluated by the operating urologist. Dexmedetomidine was diluted in normal saline to a concentration of 4 µg/ml. In all of the cases, 0.5 µg/kg dexmedetomidine was injected intravenously. RESULTS: The incidence of intraoperative penile erection was 0.34% for general anaesthesia, 0.11% spinal anaesthesia and 1.72% epidural anaesthesia at our institution. Detumescence was achieved in 9 patients during the first 5 min and in one patient at the 9th minute after a single intravenous dexmedetomidine (83%). There was no detumescence in two patients after 15 min (17%). CONCLUSION: This study demonstrated that 0.5 µg/kg intravenous injection of dexmedetomidine is a simple, effective and safe method for immediate relief of intraoperative penile erection with high success rate.

BACKGROUND: Injury of a peripheral nerve may lead to neuropathic pain, a form of chronic pain that does not respond to traditional pain therapies. The aim of this study was to investigate the effect of pulsed radiofrequency (PRF) applied to the L5 and L6 dorsal roots on the neuropathic pain that develops after sciatic nerve injury in rabbits. METHODS: In this study, 18 New Zealand rabbits were used. These were divided into 3 groups. In groups 1 and 2, the left sciatic nerve was tightly ligated as a partial ligation model with 4-0 silk sutures. Group 3 was a sham group. Pulsed radiofrequency was applied to group 1 rabbits on both dorsal roots at 42 degrees C for 8 mins. The responses of all the groups to thermal and mechanical stimuli were measured for a period of 4 weeks after this process. RESULTS: Ten days after ligation of the left sciatic nerve and before PRF application, neuropathic pain occurred; the responses of groups 1 and 2 to the hot plate test and to the mechanical stimulus were lower (P < 0.005) when compared with the baseline values. There were no statistically significant differences between baseline values and group 1 rabbits' responses to the hot plate test 2 weeks after the application of PRF or to the mechanical stimulus 3 weeks after RF application. The decrease seen in group 2 persisted after 4 weeks (P < 0.001). CONCLUSIONS: The hyperalgesia that develops as a result of neuropathic pain in rabbits was observed to be reduced by PRF application.
