An Eastern Europe and Middle East multinational expert Delphi consensus study on the prevention, diagnosis, and treatment of developmental dysplasia of the hip before walking age.

PURPOSE: The incidence of developmental dysplasia of the hip (DDH) is higher in Eastern Europeans and Middle Easterners. This study aimed to establish consensus among experts in this geographical area on the management of DDH before walking age. METHODS: Fourteen experienced orthopedic surgeons agreed to participate in a four-round online consensus panel by the Delphi method. The questionnaire included 31 statements concerning the prevention, diagnosis, and treatment of DDH before walking age. RESULTS: Consensus was established for 26 (84%) of 31 statements. Hip ultrasonography is the proper diagnostic tool under six months in DDH; universal newborn hip screening between three and six weeks is necessary; positive family history, breech presentation, female gender, and postnatal swaddling are the most important risk factors; Ortolani, Barlow tests, and limitation of abduction are the most important clinical findings; Pavlik harness is the first bracing preference; some Graf type IIa hips and all Graf type IIb and worse hips need abduction bracing treatment; the uppermost age limit for closed and open reductions is 12 months and 12-24 months, respectively; anatomic reduction is essential in closed and open reductions, postoperative MRI or CT is not always indicated; anterior approach open reduction is better than medial approach open reduction; forceful reduction and extreme positioning of the hips (> 60° hip abduction) are the two significant risk factors for osteonecrosis of the femoral head. CONCLUSION: The findings of the present study may be useful for clinicians because a practical reference, based on the opinions of the multinational expert panel, but may not be applicable to all settings is provided.

Impact of Inflammation-Related Genes on COVID-19: Prospective Study at Turkish Cohort.

The pandemic coronavirus disease 2019 (COVID-19) has caused a high mortality rate and poses a significant threat to the population. The disease may progress with mild symptoms or may cause the need for intensive care, depending on many factors. In this study, it was aimed to determine if there is a tendency due to genetic factors in COVID-19 patients. Ninety-four of 188 patients with mild clinical and 94 with severe clinical symptoms were included in the study. The targeted panel including coagulopathy (F2, F5), viral invasion (ACE2), and inflammation (CXCL8, IFNAR2, IFNL4, IL10, IL2, IL6, IRF7, TLR3, TLR7, TNF) related genes was performed sequenced by the next generation sequencing (NGS). The variants found were classified and univariate analyses were performed to select candidate variables for logistic model. Risk factors and variants were compared. It was revealed that the presence of 2 or more risk factors caused the disease to progress severely (p < 0.001). Heterozygous IRF7:c.1357-23dup variant had a 2.5 times higher risk for mild disease compared to severe disease. Other variants were found to be more significant in mild disease. Since polymorphic variants were not evaluated in the literature, the findings of our study could not be compared with the literature. However, as variants that may be effective in the severity of infections may differ according to ethnicity. This study has the feature of being a guide for subsequent studies to be carried out especially in Turkish population. Clinical course of the COVID-19 is likely to depend on a variety of risk factors, including age, sex, clinical status, immunology and genetic factors.

Clinical Practice Patterns and Evidence-Based Medicine in Rhinoplasty: A 10-Year Review of Continuous Certification Tracer Data from the American Board of Plastic Surgery.

BACKGROUND: The American Board of Plastic Surgery (ABPS) has collected data on cosmetic surgery from member surgeons since 2003. These data offer valuable information on national trends in clinical practice. OBJECTIVES: The present study was performed to analyze trends in rhinoplasty over the last decade. METHODS: Tracer data were compared between two cohorts 2012-2016 (early cohort "EC") and 2017-2021 (recent cohort "RC"). Data included patient demographics and surgical techniques. Results were considered in the context of current EBM-based guidance in the plastic surgery literature. RESULTS: Data from 730 rhinoplasties (270 EC and 460 RC) were analyzed. The median age was 30 years, and the most common patient concern was the nasal dorsum (79%). In the RC group, fewer patients voiced concerns about tip projection (58% vs 43%, p = 0.0002) and more complained of functional airway problems (38% vs 49%, p = 0.004). An open approach was most common (83%). Septoplasty (47% vs 52%, p = 0.005), caudal septum repositioning (14% vs 23%, p = 0.002), and tip rotation maneuvers (32% vs 49%, p < 0.0001) became more popular. There was also an increase in the use of spreader grafts (35% vs 45%, p = 0.01) and columellar strut grafts (42% vs 50%, p = 0.04), while there has been a decrease in alar base resection (17% vs 10%, p = 0.007) and non-cartilaginous dorsum/radix augmentation (9% vs 4%, p = 0.02). CONCLUSIONS: ABPS tracer data provide an excellent resource for the objective assessment of procedures in plastic surgery. The present study is the first to highlight evolving trends in rhinoplasty over the last 10 years.

The impact of initial hematocrit values after birth on peri-/intraventricular hemorrhage in extremely low birth weight neonates.

AIM: Peri-/intaventricular hemorrhage (P/IVH) is a common condition in preterm neonates and is responsible for substantial adverse neurological outcome especially in extremely low birth weight infants. As hematocrit after birth is a surrogate marker for blood volume, this study aimed to evaluate the effect of initial hematocrit values after birth on P/IVH development in extreme low birth weight (ELBW) neonates. PATIENTS AND METHODS: A prospective cohort analysis of 92 eligible ELBW neonates was performed. The relationship between initial hematocrit values in ELBW neonates after birth and subsequent development of P/IVH was examined. RESULTS: Twenty-nine of 92 infants developed P/IVH. There were significant differences in initial Hct and maximum carbon dioxide (max PCO2) in the first 3 days levels in the P/IVH group compared with no P/IVH group. Initial Hct level at birth in the P/IVH group were significantly lower than the no P/IVH group while max PCO2 in the first 3 days were found to be significantly high in the P/IVH group. There were no significant differences in other baseline demographic, perinatal, and neonatal characteristics while in univariate analysis, higher gestational age and initial Hct were associated with decreased likelihood of P/IVH. In multiple regression analysis after adjustment, only initial Hct remained significantly associated with P/IVH. There was no difference between the population by subgroups of IVH (IVH I-II and IVH III-IV) according to hematocrit and the severity of IVH. CONCLUSION: Higher initial Hct at birth is associated with decreased P/IVH in ELBW infants. We hypothesized the argument that ELBW infants who have lower initial Hct at birth have less suboptimal volume status that predisposing lower cerebral blood flow and the resultant decrease in cerebral blood flow precede the development of P/IVH.

Management and referral patterns for new-onset chronic cough in primary care patients.

Background: The diagnosis and management of chronic cough in primary care is challenging despite it being one of the most common chronic conditions. Objective: Clinical characterization of patients with new-onset chronic cough in the primary care setting. Methods: This was a retrospective study of adult patients (ages ≥ 18 years) with at least three visits with primary care providers (PCP) for new-onset cough, with at least 8 weeks between the first and third visits, within a tertiary-care center and affiliated clinics between January 1, 2010, and January 1, 2019 (N = 174). We calculated the frequency of primary care visits, diagnostic testing, specialist referrals, and prescribed medications up to 18 months after the third visit with a PCP for cough. Results: Of 174 patients who met the criteria of new-onset chronic cough, >50% had four or more primary care visits related to cough. Despite that, 91 (52.3%) did not receive a referral to a specialist, and 41 (23.5%) did not receive an order for a chest radiograph during the evaluation of the chronic cough. Antibiotics and systemic corticosteroids were prescribed to 106 (61%) and 63 (36%) of the patients, respectively, and 20% were prescribed opiates. No patients were prescribed central-neuromodulating agents, and angiotensin-converting enzyme inhibitors were discontinued in 48% of the patients who were taking them (12/25). Conclusion: We found considerable heterogeneity and discrepancies with clinical guideline recommendations in patients who presented with new chronic cough. There is a substantial unmet need to study chronic cough in the primary care setting to inform important stakeholders.

Ultrasound Diagnosis of Prenatal Cleft Lip: How Does Its Accuracy Affect the Family?

ABSTRACT: Factors impacting the accuracy of ultrasound (US) diagnosis of cleft lip (CL) and its subsequent effect on parents are not well understood. Our objectives were to evaluate how the type of CL (complete versus incomplete) and associated cleft palate affect the accuracy of CL's prenatal diagnosis and to evaluate differences between parents' perception of prenatal US in cases of true-positive versus false-negative results. The authors performed a retrospective review of all patients who underwent repair for nonsyndromic CL following prenatal US. Patients were stratified by type of CL and associated cleft palate. Parents were called to determine if their child's CL was diagnosed via US and their perception of the results. Forty-seven children with complete and 40 with incomplete CL responded to phone calls. The presence of a complete CL (P = 0.001) and an associated cleft palate (P = 0.014) were independently associated with an increased likelihood of prenatal diagnosis. Parents who received a true-positive prenatal diagnosis of CL were more satisfied than those who received a false-negative diagnosis (P = 0.0063). True-positives perceived knowing of their child's diagnosis in advance to be more helpful than false-negatives believed it would have been. These results afford an improved context to interpret US studies and help physicians provide more informed prenatal counseling.

Development and Validation of a Scale to Measure Fear of Activity in Patients With Coronary Artery Disease (Fact-CAD).

OBJECTIVE: To develop and validate a scale to measure fear of activity in patients with coronary artery disease. DESIGN: Psychometric study. SETTING: Outpatient cardiology clinics. PARTICIPANTS: The scale was applied to patients who had myocardial infarction, coronary artery bypass grafting, or percutaneous coronary intervention within the last 12 months (N=250). INTERVENTIONS: A scale for fear of activity in patients with coronary artery disease (Fact-CAD) was created through semistructured focus group interviews with patients. Face and content validity of Fact-CAD was verified. MAIN OUTCOME MEASURES: Psychometric analysis included model fit, unidimensionality, reliability, local dependency, differential item functioning, and external construct validity. Analyses were performed using the Rasch Analysis Model. RESULTS: Fact-CAD scale was a reliable (high Person Separation Index of 0.89) and valid (unidimensional, no misfit, local independency supported, no residual correlations) measure of fear of activity. Three items showed differential item functioning according to employment status, marital status, and angina pectoris, which were not assigned as real item bias by experts and remained in the model. CONCLUSION: Fact-CAD was supported by Rasch analysis as a psychometrically valid scale to evaluate fear of activity in patients with coronary artery disease.

The Global Spine Care Initiative: a consensus process to develop and validate a stratification scheme for surgical care of spinal disorders as a guide for improved resource utilization in low- and middle-income communities.

PURPOSE: The purpose of this study was to develop a stratification scheme for surgical spinal care to serve as a framework for referrals and distribution of patients with spinal disorders. METHODS: We used a modified Delphi process. A literature search identified experts for the consensus panel and the panel was expanded by inviting spine surgeons known to be global opinion leaders. After creating a seed document of five hierarchical levels of surgical care, a four-step modified Delphi process (question validation, collection of factors, evaluation of factors, re-evaluation of factors) was performed. RESULTS: Of 78 invited experts, 19 participated in round 1, and of the 19, 14 participated in 2, and 12 in 3 and 4. Consensus was fairly heterogeneous for levels of care 2-4 (moderate resources). Only simple assessment methods based on the clinical skills of the medical personnel were considered feasible and safe in low-resource settings. Diagnosis, staging, and treatment were deemed feasible and safe in a specialized spine center. Accurate diagnostic workup was deemed feasible and safe for lower levels of care complexity (from level 3 upwards) compared to non-invasive procedures (level 4) and the full range of invasive procedures (level 5). CONCLUSION: This study introduces a five-level stratification scheme for the surgical care of spinal disorders. This stratification may provide input into the Global Spine Care Initiative care pathway that will be applied in medically underserved areas and low- and middle-income countries.

Nomogram with potential clinical use to predict lymph node metastasis in endometrial cancer patients diagnosed incidentally by postoperative pathological assessment.

PURPOSE: To determine the clinical and pathological risk factors for lymph node metastasis (LNM) in patients with endometrial cancer and to create a nomogram to predict LNM in patients without surgical staging. METHODS: All patients with endometrial adenocarcinoma who were treated surgically at a university based gynecologic oncology clinic between January 2011 and December 2014 were recruited. Women with endometrial adenocarcinoma who were surgically staged including lymphadenectomy were included in the study. Data regarding clinical and pathological risk factors were recorded. The histopathologic slides from the staging surgeries were re-evaluated microscopically by a gynecologic pathologist for all parameters along with lymphovascular space invasion (LVSI). RESULTS: A total of 279 patients with endometrial cancer were analyzed. Among those, 31 (11.1%) had lymph node metastasis. According to the univariate analyses, elevated CA 125 (>35 U/mL), LVSI, myometrial invasion ≥50%, grade 3 disease, non-endometrioid type, and cervical stromal involvement were significantly associated with LNM. The multivariate logistic regression analysis showed that LVSI, non-endometrioid type, elevated CA 125, and cervical stromal involvement increased the risk of LNM. However, myometrial invasion and grade did not significantly affect the risk of LNM. A nomogram to predict LNM was constructed using these factors (concordance index 0.92). CONCLUSIONS: LVSI is the most important predictor for LNM. The present nomogram can be useful to decide if adjuvant therapy is required for patients who undergo simple hysterectomy for a benign etiology and incidentally diagnosed with endometrial cancer by pathological evaluation.

A decision analysis to identify the ideal treatment for adult spinal deformity: is surgery better than non-surgical treatment in improving health-related quality of life and decreasing the disease burden?

BACKGROUND: Adult spinal deformity (ASD) is a major public health problem. There are pros and cons of the available treatment alternatives (surgical or non-surgical) and it had been difficult to identify the best treatment modality. AIM: To construct a statistical DA model to identify the optimum overall treatment in ASD. METHODS: From an international multicentre database of ASD patients (968 pts), 535 who had completed 1 year follow-up (371 non-surgical-NS, 164 surgical-S), constitute the population of this study. DA was structured in two main steps of: (1) baseline analysis (assessing the probabilities of outcomes, assessing the values of preference-utilities-, combining information on probability and utility and assigning the quality adjusted life expectancy (QALE) for each treatment) and (2) sensitivity analysis. RESULTS: Four hundred and thirty-two patients (309 NS, 123 S) had baseline and 1 year follow-up ODI measurements. Overall, 104 (24.1 %) were found to be improved (a decrease in ODI > 8 points), 225 (52.1 %) unchanged (-8 > ODI > 8) and 65 deteriorated. Surgery presented with a higher chance of improvement (54.2 %) versus NS (9.7 %). The overall QALE ranged from 56 to 69 (of 100 years) and demonstrated better final QALE in the NS group (60 vs. 65, P = 0.0038), this group having started with higher QALE as well (56 vs. 65 years, P < 0.0001). There were improvements in overall QALE in both groups but this was significant only in the surgical group (S from 56 to 60 years, P < 0.0001; NS from 65 to 65 years, P = 0.27). In addition, in the subgroup of patients with significant baseline disability (ODI > 25) surgery appeared to yield marginally better final QALE (58 vs. 56 years, P = 0.1) despite very a similar baseline (54 vs. 54 years, P = 0.93). DISCUSSION AND CONCLUSIONS: This study demonstrated that a single best treatment modality for ASD may not exist. Conservative treatment appears to yield higher (up to 6 %) QALE compared to surgery, most probably secondary to a higher baseline QALE. On the other hand, surgery provides a significantly higher increase in QALE. Especially in patients with significant disability at baseline, the final QALE tended higher in the S group (although not significant). Finally, chances of a relevant improvement at first year turned out to be significantly lower with NS treatment.

Analysis of the reliability of surgeons' ability to differentiate between idiopathic and degenerative spinal deformity in adults radiologically. What descriptive parameters help them decide?

PURPOSE: Adult spinal deformity (ASD) may be classified as idiopathic (ID) or degenerative (DD) (or other) based on classifier's perception, the reliability of and factors inherent to which remain unknown. The aim of this study is to evaluate the inter- and intra-observer reliability of surgeons' perception in differentiating ID from DD and to identify the determinants of this differentiation. METHODS: From a multicentric prospective database of ASD, 179 patients were identified with the diagnosis of ID (n = 103) or DD (n = 76); without previous surgery; and a lumbar coronal curve larger than 20°. Standing antero-posterior and lateral X-rays of these patients were sent to five experienced spine surgeons to be identified as DD or ID (or other); followed by a second round after reshuffling. Weighted kappa statistics were used, the strength of agreement for the kappa coefficient was considered as; 0.81-1 = almost perfect, 0.61-0.8 = substantial, 0.41-0.60 = moderate, 0.21-0.40 = fair, 0.01-0.20 = slight, and ≤0 = poor. Patients were then stratified based on the number of agreements on a total of 10 rounds as excellent (10 out of 10), good (more than 7 out of 10) and fair/poor (7 and less). These excellent and good agreements were further compared for additional radiological parameters. RESULTS: Agreement levels were moderate to substantial for intra but mostly fair for inter-observer comparisons. For ID patients, there were 42 cases with excellent and 38 with very good agreement whereas for DD, there were no excellent and only 17 cases with very good agreement. Upon comparison of these (ID vs DD for at least very good cases), it was seen that they were different for some coronal parameters such as lumbar Cobb angle (larger in ID, p < 0.001), central sacral vertical line (CSVL) modifier (C more common in ID, p = 0.007) and presence of rotatory subluxation (less common in DD, p = 0.017), but very different for sagittal parameters (lumbar lordosis, sagittal vertical axis, T2 sagittal tilt, pelvic tilt, sacral slope, and global tilt; increased sagittal imbalance in DD, all p ≤ 0.001). CONCLUSION: Surgeons in this study demonstrated reasonable (moderate to substantial) intra-observer agreement, but only fair agreement amongst them. Alarming as it may appear, we should be cautious in interpreting these results based on only radiology and no clinical information. In patients with good agreement, the most consistent radiologic determinant of degenerative ASD appeared to be the presence of sagittal imbalance.

Safety and efficacy of osteotomies in adult spinal deformity: what happens in the first year?

PURPOSE: Spinal surgery for adult spinal deformity (ASD) may require the use of osteotomies, which may have high complication rates (up to 80 %). These may be expected to affect health-related quality of life (HRQOL) in the early postoperative phase but little is known about the clinical course of these patients in the first year following surgery. The aim of the study is to evaluate the radiological results and HRQOL in patients undergoing a spinal osteotomy for ASD within the first year following surgery with special reference to the effect of complications. METHODS: From a prospective multicenter ASD database, patients who had undergone a Smith-Petersen osteotomy (SPO), pedicle substraction osteotomy (PSO), vertebral column resection (VCR) or any combination of these were reviewed for radiological sagittal alignment parameters [sagittal vertical axis (SVA), global tilt, lumbar lordosis, T2-sagittal tilt (ST)] as well as HRQOL [Oswestry Disability Index (ODI), short form-36 items (SF-36) Physical Component Score (PCS), SF-36 mental CS (MCS), Scoliosis Research Society (SRS)-22 questionnaire (SRS-22) subtotal] preoperatively and at the 6th- and 12th-month follow-ups with special reference to complications classified as major (life threatening or requiring additional surgery) and minor and their effects on HRQOL. RESULTS: 121 patients (85 F, 36 M) with a total of 71 SPOs, 45 PSOs and 13 VCRs were evaluated. Osteotomy resulted in correction of the major coronal Cobb angle from 43.0 ± 3.7° to 24.8 ± 2.8° (p < 0.001) and the SVA from 69.0 ± 10.3 to 52.4 ± 6.6 mm (p = 0.001). Other radiological parameters showed no significant changes. Remarkable improvements in HRQOL scores with a strong age effect (p ≤ 0.01), for all instruments except SF-36 MCS, were found. Most of these HRQOL improvements have been achieved within the first 6 months. A total of 114 complications (59 major, 55 minor) that had a lesser effect on the age-adjusted HRQOL scores (p < 0.05) (except for the SF-36 PCS) and 1 death were observed. CONCLUSIONS: Osteotomies were moderately effective in radiological improvement but resulted in a significant increase in HRQOL. They were associated with a high rate of complications but these had no/minimal effect on the clinical outcome. Contrary to the general perception, the greatest improvements in HRQOL were seen to take place during the first 6 months after surgery, even in the presence of complications.

Sagittal alignment of cervical spine in adult idiopathic scoliosis.

PURPOSE: Alignment of the cervical spine (CS) in adolescent idiopathic scoliosis (IS) as well as in asymptomatic adult populations has recently been studied and described as being less lordotic in the adolescent IS population. However, few studies have examined the sagittal alignment of the CS in adult IS or its association with other radiological variables and clinical relevance. The aim of this study is to analyse the sagittal alignment of CS in adult IS and its association with age, alignment of the thoracic, lumbar and global spinal column as well as health-related quality of life (HRQOL) parameters. METHODS: A retrospective review of prospectively collected data from a multicenter database was performed. Of 468 consecutive adult IS patients, 213 were included in the study; the remainder were excluded due to poor quality X-rays where the CS was not properly visible, or previous surgery. X-rays were measured for the following CS parameters: [Cranial base-C2 (C0-C2) lordosis, C2-C7 lordosis, thoracic (T1) slope, thoracic inlet angle (TIA) and odontoid (Od)-T1 offset using a measurement software]. These measurements were then evaluated for possible associations with patient age and with pre-existing alignment parameters and HRQOL scores using Pearson correlation tests. RESULTS: The average and standard deviations for CS alignment parameters were 32.3° ± 10.2° for C0-C2; 5.7° ± 14.1° for C2-C7; 23.9° ± 11.3° for T1 slope, 70.5° ± 14.7° for TIA and 20.8° ± 16.5° for Od-T1 offset. CS alignment showed a significant (p < 0.05) correlation with age, T kyphosis and several other sagittal alignment parameters such as sagittal vertical axis (SVA), global tilt and T1 sagittal tilt, but not with the HRQOL parameters. CONCLUSION: The sagittal alignment of the CS in adult IS is less lordotic than the normal average while less kyphotic than that of IS of a younger age. It correlates with age, thoracic kyphosis and some global sagittal alignment parameters. These findings suggest that CS alignment is likely a component of the global sagittal alignment strongly affected by thoracic kyphosis, and most probably does not affect HRQOL by itself.

CBCT quantitative evaluation of mandibular lingual concavities in dental implant patients.

PURPOSE: The purpose of this study was to evaluate the prevalence of mandibular lingual concavities and to measure them using CBCT (Cone-Beam Computerized Tomography). METHODS: In this study, CBCT scans of 200 patients requiring dental implants were assessed for lingual concavities. Reconstructed CBCT images were transferred as DICOM files to the 3D DOCTOR software program, and metric, volumetric, and surface area measurements were obtained. Two-way mixed ANOVA was used to model side (left/right, anterior), measurement type, and gender with side and type taken as within-subject variables, gender as between-subject variables, and age as a covariate. A comparison between the dentate and edentulous groups in the samples with lingual concavities was performed using an unpaired Student's t test. RESULTS: Submandibular concavity mean depth and volume were found to be 2.4 mm and 130.7 mm(3), whereas mean depth and volume of sublingual concavities were found to be 1.3 mm and 26.5 mm(3). Significant inverse ratios were found between age and volume and between age and surface area (p < 0.05). All measurements were higher in males than females, but the differences were not statistically significant. The differences between the presence of concavity (sublingual, right, and left submandibular) and dental status (dentate/edentulous) were statistically insignificant (p > 0.05). CONCLUSION: Mandibular lingual concavity dimensions were found to vary by age, location, and the presence/absence of teeth. Third party software can be used to generate 3-dimensional models that provide useful information about shape, size, and location of sublingual and submandibular concavities prior to implant placement.

Permanent Peripheral Nerve Stimulator for Complex Regional Pain Syndrome of the Forearm and Hand.

A 51-year-old woman with diabetes and depression was referred to the anesthesia pain clinic with a 15-year history of complex regional pain syndrome type I of the right forearm and hand in the radial sensory nerve distribution. There was no recognized antecedent trauma and she had failed both medical treatment and radial sensory nerve decompression surgery. An ultrasound-guided local anesthetic block of the radial nerve in the upper arm resulted in partial and temporary improvement in pain. She subsequently underwent trial of a peripheral nerve stimulator (PNS) followed by permanent PNS implant placement over the radial nerve proper proximal to the elbow. Within the first month of use, she endorsed substantially improved pain and strength in her right hand. These improvements were sustained for more than 1 year. Applications of PNS technology for treatment of extremity complex regional pain syndrome and neuropathic extremity pain in general are reviewed.

A Delphi consensus study on the treatment of slipped capital femoral epiphysis: Considerable consensus in mild and moderate slips and limited consensus in severe slips.

Purpose: The aim of this expert consensus study was to establish consensus on the treatment of different types of slipped capital femoral epiphysis and on the use of prophylactic screw fixation of the contralateral unaffected side. Methods: In this study, a four-round Delphi method was used. Questionnaires including all possible theoretical slip scenarios were sent online to 14 participants, experienced in the field of children's orthopedics and in the treatment of hip disorders in children. Results: In-situ fixation was considered to be the first treatment choice in all types of mild slip scenarios and in moderate, stable ones. Performing in-situ fixation was not favored in moderate, unstable, and in all severe slip scenarios. In moderate to severe, unstable slip scenarios, there was consensus on the use of gentle closed or open reduction and internal fixation. Any consensus was not established in the optimal treatment of severe, stable slips. There was also consensus on the use of prophylactic screw fixation of the contralateral side in case of co-existing endocrine disorder and younger age. Conclusions: The establishment of consensus on the treatment of all types of slipped capital femoral epiphysis even among the experienced surgeons does not seem to be possible. The severity of the slip and stability of the slip are the primary and secondary determinants of the surgeons' treatment choices, respectively. In-situ fixation is still the preferred treatment option in several slip types. Gentle capital realignment by closed or open means is recommended in displaced, unstable slips. Prophylactic screw fixation of the contralateral side is indicated under certain circumstances. Level of evidence: level V.

A 15-Year Review of Clinical Practice Patterns and Evidence-Based Medicine in Carpometacarpal Joint Arthroplasty.

BACKGROUND: The purpose of this study was to help understand national practice patterns in carpometacarpal (CMC) arthroplasty and how they have evolved with evidence-based recommendations over the past 15 years. METHODS: The American Board of Plastic Surgery (ABPS) started collecting practice data on primary CMC joint arthroplasty in 2006 as a portion of its continuous certification (CC) process. Data on primary CMC arthroplasty from May 2006 through December 2013 were reviewed and compared to those from January 2014 to March 2020. National practice trends observed in these data were evaluated. Comprehensive evidence-based medicine reviews published in 2008, 2011, 2013, and 2017 were reviewed alongside the CC data. RESULTS: In all, 570 primary CMC joint arthroplasty cases were included from May 2006 to March 2020. The average age at the time of repair was 62 years and the patient population was predominantly female (79%). Most cases were done under general anesthesia (69%), and there was an increase in the use of regional anesthesia with nerve block when our 2 cohorts were compared (27% vs 37%; P = .020). A trapezium excision with flexor carpi radialis tendon ligament reconstruction was the most popular technique (72%) and an increase in the use of simple trapeziectomy was observed (6% vs 14%; P = .001). One-third of patients did not receive any form of deep vein thrombosis prophylaxis. CONCLUSIONS: The ABPS CC data provide a databank that allows for direct observation of national practice trends and sheds light on potential avenues for improvement in patient care.

Evaluation of the effect of pitavastatin on motor deficit and functional recovery in sciatic nerve injury: A CatWalk study.

Objectives: This study aims to investigate the electrophysiological, scintigraphic, and histopathological effects of pitavastatin and its impact on functional status in rats with sciatic nerve injury. Materials and methods: A total of 30 Wistar albino rats were divided into three equal groups including 10 rats in each group: sham group (no injury), control group (nerve injury induced), and pitavastatin group (nerve injury induced and 2 mg/kg of pitavastatin administered orally once a day for 21 days). Before and at the end of intervention, quantitative gait analysis with the CatWalk system and sciatic nerve conduction studies were performed. After the intervention, the gastrocnemius muscle was scintigraphically evaluated, and the sciatic nerve was histopathologically examined. Results: There was no significant difference in the sciatic nerve conduction before the intervention and Day 21 among the groups (p>0.05). According to the quantitative gait analysis, there were significant differences in the control group in terms of the individual, static, dynamic, and coordination parameters (p<0.05). The histopathological examination revealed a significant difference in the total myelinated axon count and mean axon diameter among the groups (p<0.001). Conclusion: Pitavastatin is effective in nerve regeneration and motor function recovery in rats with sciatic nerve injury.
