Objective: To estimate the effects of initiation of epidural analgesia on fetal heart rate (FHR) patterns compared with intravenous meperidine analgesia.Methods: Fetal heart rate patterns in 200 nulliparous women with term pregnancies randomized to epidural analgesia with 0.25% bupivacaine were compared with those of 156 similar women given intravenous meperidine. Fetal heart rate patterns occurring within 40 minutes of initiation of labor analgesia were retrospectively read by three maternal-fetal medicine specialists who were blind to clinical events, including type of labor analgesia.Results: Meperidine, compared with epidural analgesia, was associated with statistically significantly less beat-to-beat variability (absent or less than 5 beats per minute) of the FHR (30% versus 7% of fetuses, P <.001) in the first 40 minutes after initiation of analgesia, as well as with fewer FHR accelerations (88% versus 62% of fetuses, P <.001). Neither the incidence of FHR decelerations nor the type of deceleration were significantly different between methods of labor analgesia. Specifically, 41% of women given meperidine exhibited FHR decelerations within 40 minutes, compared with 34% given epidural analgesia (P =.353).Conclusion: Epidural analgesia does not have deleterious effects on FHR.

In science and engineering libraries, conference publications of the Institute of Electrical and Electronics Engineers (IEEE) represent a valuable source of technical information. Libraries differ in their treatment of these publications, with some titles being cataloged as monographs and others as serials. A use study was conducted at the University of Akron to compare the relative accessability of IEEE monographs and serials. The results of this study found that IEEE publications cataloged as monographs received twice as much use as those cataloged as serials. This suggests that monographic records with individual thematic conference titles, geographic locations, conference-specific subject headings and partial or full table of contents notes produce more uses than serial records with limited generic titles and fewer subject headings.

Faced with a shortage of shelf-space in 1994, librarians at the University of Akron Science and Technology Library selected and relocated over 50,000 low-use serials volumes to a remote storage facility. An examination of the requests for articles and volumes from storage indicates that in-house use data can be used to accurately predict future low use volumes. However, a comparison of pre-storage and post-storage use clearly indicates a dramatic decrease in the use of the volumes in storage, demonstrating that storage can be a significant disincentive to patrons' use of serials.

OBJECTIVES: Having parents present during cardiopulmonary resuscitation is becoming a common practice in pediatrics. This study aimed to determine parents' perception of the effects of their presence during the resuscitation efforts of their child and whether they would recommend the experience to other families. METHODS: This study included parents or guardians of children who underwent cardiopulmonary resuscitation, and died at least 6 months before the interview. After telephone consent was obtained, a survey questionnaire was completed. The interviewees answered whether they were asked to be present, whether they had physical contact with their child, and whether the experience frightened them or gave them and their child comfort. The interviewees were asked to express their feelings about what was helpful to them and what could be done to improve the experience. RESULTS: A total of 41 interviews were conducted, and responders were divided into 2 groups: 21 in the present group and 20 in the not-present group for cardiopulmonary resuscitation. Twelve (60%) of those in the not-present group believed that their presence would have comforted the child, and 50% (10 of 20) believed that it would have helped them accept the child's death. Of those in the present group, 67% (8 of 12) believed that touching their child brought comfort, 29% (6 of 21) felt scared during cardiopulmonary resuscitation, 71% (15 of 21) believed that their presence comforted their child, and 67% (14 of 21) believed that their presence helped them adjust to the loss of the child. The majority in both groups (63% [26 of 41]) would recommend being present during cardiopulmonary resuscitation. CONCLUSIONS: This study supports encouraging family presence during cardiopulmonary resuscitation. The majority of parents who had been present and those who had not been present believed that all families should be given the option to be present. [ABSTRACT FROM AUTHOR]

Background: Retained sponges (gossypiboma) following vaginal delivery are an uncommon occurrence. Although significant morbidity from such an event is unlikely, there are many reported adverse effects, including symptoms of malodorous discharge, loss of confidence in providers and the medical system, and legal claims.Objective: To report a protocol intended to reduce the occurrence of retained sponges following vaginal delivery.Methods: After identification of limitations with existing delivery room protocols, we developed a sponge count protocol to reduce occurrence of retained vaginal sponges. We report our experience at Naval Medical Center Portsmouth, a large tertiary care military treatment facility with our efforts to implement a sponge count protocol to reduce retained sponges following vaginal delivery.Conclusions: With appropriate pre-implementation training, protocols which incorporate post-delivery vaginal sweep and sponge counts are well accepted by the health care team and can be incorporated into the delivery room routine.

This study aimed to uncover novel genes associated with neurodevelopmental disorders (NDD) by leveraging recent large-scale de novo burden analysis studies to enhance a virtual gene panel used in a diagnostic setting. We re-analyzed historical trio-exome sequencing data from 745 individuals with NDD according to the most recent diagnostic standards, resulting in a cohort of 567 unsolved individuals. Next, we designed a virtual gene panel containing candidate genes from three large de novo burden analysis studies in NDD and prioritized candidate genes by stringent filtering for ultra-rare de novo variants with high pathogenicity scores. Our analysis revealed an increased burden of de novo variants in our selected candidate genes within the unsolved NDD cohort and identified qualifying de novo variants in seven candidate genes: RIF1, CAMK2D, RAB11FIP4, AGO3, PCBP2, LEO1, and VCP. Clinical data were collected from six new individuals with de novo or inherited LEO1 variants and three new individuals with de novo PCBP2 variants. Our findings add additional evidence for LEO1 as a risk gene for autism and intellectual disability. Furthermore, we prioritize PCBP2 as a candidate gene for NDD associated with motor and language delay. In summary, by leveraging de novo burden analysis studies, employing a stringent variant filtering pipeline, and engaging in targeted patient recruitment, our study contributes to the identification of novel genes implicated in NDDs., (© 2024.

Burns of the hand are prevalent and must be managed aggressively in the acute phase to prevent deformity and disability. Proper early wound management, achieving durable soft tissue coverage, and appropriate positioning in the acute period offer substantial benefits to patients long-term. When contractures occur, secondary procedures are often indicated, and they range from laser therapy to local/regional flap coverage; rarely free flaps are used. Boutonniere deformities are common, and unfortunately, at times finger amputation renders the hand more functional than further efforts at reconstruction., Competing Interests: Disclosure The authors have no financial relationships to disclose., (Published by Elsevier Inc.)

Introduction: Whether endoscopic carpal tunnel release (ECTR) versus open carpal tunnel release (OCTR) has superior outcomes remains a controversial topic. Therefore, we sought to perform an umbrella review and meta-analysis to compare ECTR and OCTR with regards to (1) postoperative functional ability, (2) operative outcomes, and (3) time to return to work., Methods: A PubMed, Scopus, and Cochrane database search was conducted for all meta-analyses comparing ECTR and OCTR performed between 2000 and 2022 in accordance to PRISMA and Joanna Briggs Institute guidance for umbrella reviews. The primary outcomes were as follows: (1) functional ability-symptoms severity, postoperative grip strength, postoperative pinch strength, 2-point discrimination, and pain; (2) operative outcomes-operation time, total complications, nerve injury, and scar-related complication; and (3) time to return to work. Quality was assessed using the Assessment of Multiple Systematic Reviews. Pooled analysis was performed to compare several clinical outcome measures between groups, depending on the availability of data using Review Manager Version 5.2.11., Results: A total of 9 meta-analyses were included, 5 were of high quality and 4 were moderate quality. For functional ability, ECTR was associated with better pinch strength after 3 months (0.70, 95% confidence interval [CI] = 0.00, 1.40, P = 0.05) and 6 months (0.77, 95% CI = 0.14, 1.40, P = 0.02, I2 = 84%). For return to work, OCTR was associated with longer return to work compared with ECTR (-10.89, 95% CI = -15.14, -6.64, P < 0.00001, I2= 83%). There were no significant differences between OCTR and ECTR in the hand function, symptom severity, grip strength, pain, operation time, and total complications., Conclusions: In an umbrella review and meta-analysis of ECTR versus OCTR, ECTR was associated with a higher pinch strength, and a shorter time to return to work. Differences in major complications, such as nerve injury, were unclear due to statistical inconsistency and bias., Competing Interests: Conflicts of interest and sources of funding: none declared.

Background: Peripheral nerve repair is limited by Wallerian degeneration coupled with the slow and inconsistent rates of nerve regrowth. In more proximal injuries, delayed nerve regeneration can cause debilitating muscle atrophy. Topical application of polyethylene glycol (PEG) during neurorrhaphy facilitates the fusion of severed axonal membranes, immediately restoring action potentials across the coaptation site. In preclinical animal models, PEG-fusion resulted in remarkable early functional recovery., Methods: This is the first randomized clinical trial comparing functional outcomes between PEG-fusion and standard neurorrhaphy. Participants with digital nerve transections were followed up at 2 weeks, 1 month, and 3 months postoperatively. The primary outcome was assessed using the Medical Research Council Classification (MRCC) rating for sensory recovery at each timepoint. Semmes-Weinstein monofilaments and static two-point discrimination determined MRCC ratings. Postoperative quality of life was measured using the Michigan Hand Questionnaire (MHQ)., Results: Forty-eight transected digital nerves (25 control, 23 PEG) across twenty-two patients were analyzed. PEG-fused nerves demonstrated significantly higher MRCC scores at 2 weeks (OR 16.95, 95% CI: 1.79 - 160.38, p = 0.008) and 1 month (OR 13.40, 95% CI: 1.64 - 109.77, p = 0.009). Participants in the PEG cohort also had significantly higher average MHQ scores at 2 weeks (Hodge's g 1.28, 95% CI: 0.23 - 2.30, p = 0.0163) and 1 month (Hodge's g 1.02, 95% CI: 0.04 - 1.99, p = 0.049). No participants had adverse events related to the study drug., Conclusion: PEG-fusion promotes early sensory recovery and improved patient well-being following peripheral nerve repair of digital nerves., (Copyright © 2024 by the American Society of Plastic Surgeons.)

Introduction: Previous studies have identified that there is limited, although expanding, access to acute hand care in Tennessee. Because of the rapid changes that occurred in health delivery and access during the coronavirus disease pandemic, we reassessed access to acute hand care, with particular interest in the utilization of telemedicine to assess if this increased access., Method: We surveyed Tennessee hospitals listed by the Tennessee Hospital Association on their management of hand trauma and availability of telemedicine programs. Census data including population demographics such as race, age, income, and county size were merged with the survey data. Descriptive analysis was performed comparing the 2021 cohort with the historic 2018 cohort and between counties that had hand care versus counties that had no hand care., Result: Survey response rate was 71.4% (n = 80 of 112). Telemedicine was used in 80% of the hospitals for other specialties but was not used for hand care. Overall, counties that offered hand trauma care reduced from 60% to 26% from 2018 to 2021 ( P < 0.001). This change was associated with a significant reduction of acute hand care among counties that were classified micropolitan (from 56.3% to 6.7%, P < 0.01). Percentage of hand specialists on staff and 24/7 specialists availability remained low and were similar to the availability in 2018., Conclusions: There was a decrease of acute hand care access in Tennessee during the coronavirus disease pandemic despite widespread utilization of telemedicine for other specialty consults. Expansion of telemedicine in acute hand care, targeted to micropolitan areas, may help to reduce variability in access to care., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Free fibula flap (FFF) and medial femoral condyle (MFC) flap are commonly used for upper extremity osseous reconstruction, yet donor-site morbidity has never been systematically compared., Methods: Patients who underwent an FFF or MFC for upper extremity extra-carpal osseous reconstruction at 3 academic hand centers were retrospectively identified. Only patients who underwent reconstruction for a defect in which either flap type is routinely used or has been described in the literature were deemed eligible. Patients who agreed to participate were asked to complete the Lower Extremity Functional Scale (LEFS) and Lower Limb Core Scale (LLCS). The reported population norm median score of LEFS is 77 points. The LLCS population norm mean score is 90.52 points., Results: Twenty-one patients (10 MFC, 11 FFF) were enrolled. The median LEFS score for patients after MFC was 76 (interquartile range [IQR], 49-80) points and 75 (IQR, 56-79) points after FFF. The median LLCS score for patients after MFC was 96.4 (IQR, 87.9-100) points and 100 (IQR, 91-100) points after FFF. Median LEFS scores were slightly below the population norm, whereas median LLCS scores were above the norm for both FFF and MFC. All patients stated they would have the surgery again and that any dysfunction or pain in the leg was justified by the benefit in the arm., Conclusions: When considering whether to use an MFC or FFF for upper extremity reconstruction, both flap types appear to result in modest and comparable donor-site morbidity.

Background: Evidence broadly identifying medications newly-initiated prior to the occurrence of a urinary tract infection (UTI) in patients with diabetes, heart failure, or both of these conditions is lacking., Objective: The aim was to broadly assess medication filling patterns and incidence of UTIs to identify medications or medication classes most frequently initiated prior to UTI occurrence., Methods: This retrospective study utilizing a national claims database examined medications commonly initiated in the six months preceding a UTI in patients with diabetes and/or heart failure. Patients with a new diagnosis of UTI, a diagnosis of diabetes and/or heart failure, continuous enrollment in the database for at least 12 months prior to the index UTI occurrence, and who initiated at least one new medication in the 6 months preceding the index UTI were evaluated., Results: 12,744 patients met criteria: 10,626 (83.4%) had a diagnosis of diabetes, 838 (6.6%) had a diagnosis of heart failure, and 1,280 (10.0%) had diagnoses for both. Opioids were the most commonly filled medication class among all three groups. Medications from the SGLT2i class were the twelfth, eleventh, and eighteenth most common medications filled prior to the index UTI for all patients, patients with diabetes, and patients with diabetes and heart failure, respectively., Conclusion: Opioids were by far the most commonly initiated medication class in the 6 months prior to UTI incidence in patients with diabetes and/or heart failure. SGLT2i medications were not commonly initiated in the 6 months prior to the occurrence of a UTI., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Magnetic resonance diffusion tensor imaging (DTI) can detect microstructural changes in peripheral nerves. Studies have reported that the median nerve apparent diffusion coefficient (ADC), a quantification of water molecule diffusion direction, is sensitive in diagnosing carpal tunnel syndrome (CTS). Five databases were searched for studies using ADC to investigate CTS. Apparent diffusion coefficient (measured in mm 2 /s) were pooled in random-effects meta-analyses. Twenty-two studies met criteria yielding 592 patients with CTS and 414 controls. Median nerve ADC were measured at the level of the distal radioulnar joint (CTS ADC: 1.11, 95% CI: 1.07-1.15, I 2 = 54%; control ADC: 1.04, 95% CI: 1.01-1.07, I 2 = 57%), pisiform (CTS ADC: 1.39, 95% CI: 1.37-1.42, I 2 = 0%; control ADC: 1.27, 95% CI: 1.23-1.31, I 2 = 59%), hamate (CTS ADC: 1.40, 95% CI: 1.36-1.43, I 2 = 58%; control ADC: 1.27, 95% CI: 1.25-1.28, I 2 = 47%), and as an combination of several measurements (CTS ADC: 1.40, 95% CI: 1.37-1.47, I 2 = 100%; control ADC: 1.39, 95% CI: 1.24-1.53, I 2 = 100%). Median nerve ADC is decreased in individuals with CTS compared to controls at the levels of the hamate and pisiform. ADC cut-offs to diagnose CTS should be established according to these anatomic levels and can be improved through additional studies that include use of a wrist coil.

Purpose: The A2 and A4 pulleys of the flexor tendon system have traditionally been considered critical components of efficient digital flexion. This dogma has recently been challenged. Using fresh human cadaveric hands and a model to measure force and excursion, we sought to clarify the clinical importance of releasing different pulleys., Methods: Combinations of A1, A2, and A4 pulleys were released on the index, middle, ring, and little fingers of fresh, cadaveric hands. The excursion was measured as the distance the tendon was pulled by the motor to achieve palm touchdown. The force applied by the motor was constant (25 N); work was derived from the product of force and excursion (distance). The change in excursion and work needed to achieve palm touchdown before and after pulley release was measured. Excursion varies among digits and specimens at baseline; therefore, the percentage change from the intact state was used to compare groups. We compared A2 versus A1, A4 versus A1, A4 versus A2, A1 + A2 versus A2, and A1 + A4 versus A4., Results: Isolated A2 or A4 release had the greatest individual impact on the excursion (4.77% ± 1.52% and 3.88% ± 1.93%, respectively). When A1 was released with A2 (9.90% ± 2.52%), the additional impact on the excursion was significant; however, when A1 was released with A4 (2.63% ± 2.81%), the impact was marginal. No clinically or statistically significant change in the work of flexion was detected., Conclusions: A1 release was clinically significant when added to A2 release but not when added to A4 release. Sacrifice of the A2 and A4 pulleys resulted in a statistically significant, but clinically negligible, difference in flexor tendon excursion. These data suggest that the A1 pulley should be preserved when other proximal pulley components are likely to be compromised. These data also add further support to the concept that the A2 pulley or the A4 pulley can be released as needed for optimal tenorrhaphy., Clinical Relevance: During flexor tendon repair, the length of contiguous pulley release may have more impact on final tendon excursion than which specific pulleys are released., (Copyright © 2021 American Society for Surgery of the Hand.

Background: Olfactory dysfunction (OD) has been reported to impact social interactions. However, the relationship between OD and loneliness has received little attention. The purpose of this study was to determine the association between OD and loneliness, controlling for patient factors., Methods: Subjects without otolaryngic complaints were enrolled and olfactory function was assessed using: Sniffin' Sticks test to measure threshold, discrimination and identification (TDI), Questionnaire of Olfactory Disorders Negative Statements (QOD-NS) and 9 - item Olfactory-Visual Analogue Scale (VAS). Loneliness was assessed using the De Jong Gierveld (DJG) and University of California Los Angeles (UCLA) loneliness scales. Bivariate analysis was performed followed by regression analysis, controlling for confounders., Results: In total, 221 subjects were included with a mean age of 50.5 years (range 20 to 93), 133 (60.2%) females and 161 (72.9%) white. Mean TDI score was 29.3 (7.0) and 49.5% of the cohort was dysosmic. Using DJG, 36.4% of the cohort were classified as lonely, whereas 35.0% were lonely using UCLA. Olfactory measures were significantly associated with DJG, including TDI ( β  = -0.03, p = 0.050), olfactory discrimination ( β  = -0.111, p = 0.005), QOD-NS ( β  = 0.058, p < 0.001) and olfactory-VAS ( β  = 0.032, p < 0.001). UCLA scores were significantly associated with QOD-NS (PR 1.061 [CI 1.018-1.107], p = 0.005) and olfactory-VAS scores (PR 1.027, [CI 1.007-1.049], p = 0.009). After controlling for confounders, the association between DJG and olfactory discrimination, as well as DJG and olfactory-VAS remained significant., Conclusions: In this community-based sample of older adults, both OD and loneliness were common. Those subjects with worse olfactory function were more likely to report loneliness. Further research is necessary to establish causality, as well as explore the role of depression.

Patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) appear to be at increased risk for venous thromboembolism (VTE), especially if they become critically ill with COVID-19. Some centers have reported very high rates of thrombosis despite anticoagulant prophylaxis. The electronic health record (EHR) of a New Orleans-based health system was searched for all patients with polymerase chain reaction-confirmed SARS-CoV-2 infection who were either admitted to hospital or treated and discharged from an emergency department between 1 March 2020 and 1 May 2020. From this cohort, patients with confirmed VTE (either during or after their hospital encounter) were identified by administrative query of the EHR.: Between 1 March 2020 and 1 May 2020, 6153 patients with COVID-19 were identified; 2748 of these patients were admitted, while 3405 received care exclusively through the emergency department. In total, 637 patients required mechanical ventilation and 206 required renal replacement therapy. Within the hospitalized cohort, the overall mortality rate was 24.5% and VTE occurred in 86 patients (3.1%). In the 637 patients who required mechanical ventilation at some point during their hospital stay, 45 developed VTE (7.2%). After a median follow-up of 14.6 days, VTE had been diagnosed in 3 of the 2075 admitted who were discharged alive (0.14%). Among 6153 patients with COVID-19 who were hospitalized or treated in emergency departments, we did not find evidence of unusually high VTE risk. Pending further evidence from prospective, controlled trials, our findings support a traditional approach to primary VTE prevention in patients with COVID-19., (© 2020 by The American Society of Hematology.)

Background: Olfactory dysfunction (OD) is common, affecting an estimated 13 million adults in the United States. Prior studies may underestimate OD prevalence due to use of brief smell identification tests or age-adjusted cutoff values, which concede that it is acceptable for older people to have a decreased sense of smell., Objective: To determine OD prevalence in the healthy community when the goal and expectation is ideal olfactory function, rather than age-based population norms. Secondary goals were to explore factors associated with OD., Methods: Subjects without otolaryngic complaints were recruited from the community surrounding the Medical University of South Carolina. Olfactory-specific information was collected, and olfactory function was assessed using the Sniffin' Sticks test (Burghardt, Wedel, Germany) to measure threshold, discrimination, and identification (TDI). OD was defined as a TDI score < 31. Bivariate analysis and linear regression were used to determine factors associated with OD., Results: In total, 176 subjects were included with mean age of 52 years (range: 20-93), 111 (63%) female, and 127 (72%) white. Mean TDI score was 28.8 (6.9) and OD was present in 94 (53%) subjects. Multivariate linear regression revealed that TDI decreased an average of 1 point every 5 years. TDI was also associated with Mini-Mental Status Examination (MMSE) score, asthma, and gastroesophageal reflux disease. Threshold was associated with age, heart problems, and gastroesophageal reflux disease. Discrimination was associated with age and MMSE scores. Identification was associated with age, heart problems, and anxiety., Conclusions: In a community-based sample, OD affects greater than 50% of subjects. Aging impacts all aspects of olfaction, while the effects of factors such as asthma, MMSE scores, gastroesophageal reflux disease, heart problems, and anxiety may only be evident in specific olfactory subtests.

Background: Olfactory dysfunction (OD) is a common problem, affecting up to 20% of the general population. Previous studies identified olfactory cleft mucus proteins associated with OD in chronic rhinosinusitis (CRS) but not in a healthy population. In this study we aimed to identify olfactory cleft mucus proteins associated with olfaction in individuals without sinus disease., Methods: Subjects free of sinus disease completed medical history questionnaires that collected data regarding demographics, comorbidities, and past exposures. Olfactory testing was performed using Sniffin' Sticks, evaluating threshold, discrimination, and identification. Olfactory cleft mucus (OC) and, in select cases, inferior turbinate mucus (IT) were collected with Leukosorb paper and assays performed for 17 proteins, including growth factors, cytokines/chemokines, cell-cycle regulators, and odorant-binding protein (OBP)., Results: Fifty-six subjects were enrolled in the study, with an average age of 47.8 (standard deviation [SD], 17.6) years, including 33 females (58.9%). The average threshold/discrimination/identification (TDI) score was 30.3 (SD, 6.4). In localization studies, OBP concentrations were significantly higher in OC than IT mucus (p = 0.006). Cyclin-dependent kinase inhibitor 2A (CDKN2A/p16INK4a), basic fibroblast growth factor (bFGF), chemokine ligand 2 (CCL2/MCP-1), granulocyte macrophage colony-stimulating factor (GM-CSF), and chemokine ligand 20 (CCL20/MIP-3a) all inversely correlated with overall TDI (all rho ≥ -0.479, p ≤ 0.004). Stem cell factor (SCF) correlated positively with overall TDI (rho = 0.510, p = 0.002)., Conclusion: Placement of Leukosorb paper is relatively site-specific for olfactory proteins and it is feasible to collect a variety of olfactory cleft proteins that correlate with olfactory function. Further study is required to determine mechanisms of OD in non-CRS subjects., (© 2019 ARS-AAOA, LLC.)

Surgical site infections (SSIs) in orthopaedics are a common complication, with more than half a million SSIs occurring in the United States each year. SSIs can carry a notable burden for patients and physicians alike. Skin antiseptic solution plays an important role in preventing SSI. Many studies have looked at different skin antiseptic solution in preventing SSIs. Different surgical preps can decrease bacterial loads at surgical sites in varying degrees. Yet, the amount of bacterial load does not always correlate with a lower risk of infection.Chlorhexidine, for example, has been shown to cause markedly less SSIs compared with povidone-iodine prep in general surgery cases. Whereas chlorhexidine with alcohol may best work in the forefoot, iodine povacrylex with alcohol is equivalent in the spine. Conversely, joint arthroplasty SSIs were markedly decreased with a combination of preps. Because of all these differences, understanding which prep solution to use and when can be invaluable to the orthopaedic surgeons.

Case: A 32-year-old right-handed surgeon presented with a history of intermittent pain at the right medial epicondyle, a mild Tinel's sign, and dysesthesia in the ulnar nerve distribution. Dynamic ultrasound demonstrated a hypertrophic anconeus epitrochlearis bilaterally, and chronic irritation of the ulnar nerve. Anterior release with myectomy of the accessory muscle was performed. No compressive symptoms were present at 1-year follow-up., Conclusions: The anconeus epitrochlearis is an often-underappreciated cause of ulnar nerve compression that can lead to significant functional impairment. Dynamic ultrasound is an excellent diagnostic modality, and anterior release with myectomy provides durable relief with minimal downtime.

Objective: The aim of this retrospective review is to evaluate trends in the management of maternal and congenital syphilis (CS) in a tertiary care center in New Orleans, LA., Study Design: All cases of maternal and neonatal syphilis over a five year period at Touro Infirmary, New Orleans, LA, were identified using ICD-9/10 codes. Charts were reviewed for demographic and obstetrical variables, stage of syphilis at diagnosis, lab values, and treatment regimen. Newborn treatment and other outcomes were recorded., Results: During the study period 106 infected mother-baby pairs were identified. Of these, 73 charts are available for review. 41% (n = 30) of women received inadequate therapy according to their stage of disease. 9% of newborns (n = 6) were found to be symptomatic for CS; however, only 83.3% of these were admitted to the neonatal intensive care unit. Only 20% (n = 6) of infants were adequately treated with an extended penicillin regimen if the mother was not adequately treated. Furthermore, only 63.0% of newborns had a nontreponemal titer performed., Conclusion: With rising rates of CS, strict adherence to the 2015 CDC guidelines for treatment of syphilis must be maintained.

Purpose: Phalangeal fractures represent a significant portion of upper extremity injuries but are not well studied as a single entity. We define our approach at a level 1 trauma center and determine whether plating or lag screws (ie, rigid fixation) have superior functional outcomes compared with Kirschner wire fixation for phalangeal or metacarpal fractures., Methods: We performed a systematic review of all surgically managed hand fracture cases at Bellevue Hospital during 2012 and 2013. Demographics, type of fixation, length of operation, period of immobilization, range of motion, time to return to work, and complications including reoperation were noted. Comparisons were assessed for significance using Student t tests and Fisher exact test (P < 0.05 considered significant)., Results: One hundred ninety-two fractures (158 patients) were treated and followed for an average of 113 days. Rigid fixation was used for 17 (19%) of 90 metacarpal fractures and 5 (5%) of 102 phalangeal fractures. Operative times were significantly shorter (59 vs 135 minutes, 84 vs 149 minutes), and period of immobilization was longer (37 vs 15 days, 34 vs 18 days) when Kirschner wires were used for metacarpal and phalangeal fractures, respectively (P > 0.05). Total active motion and return to work were similar regardless of type of intervention in both fracture types. No patients treated with rigid fixation required reoperation., Conclusions: To our best knowledge, this is the first review to study phalangeal fractures concurrently but also separately from metacarpal fractures. Despite shorter periods of immobilization, rigid fixation does not appear to lead to improved total active motion or time to return to work.

Background: In 2012, yoga was practiced by 20 million Americans, of whom 82% were women. A recent literature review on prenatal yoga noted a reduction in some pregnancy complications (ie, preterm birth, lumbar pain, and growth restriction) in those who practiced yoga; to date, there is no evidence on fetal response after yoga., Objectives: We aimed to characterize the acute changes in maternal and fetal response to prenatal yoga exercises using common standardized tests to assess the well-being of the maternal-fetal unit., Study Design: We conducted a single, blinded, randomized controlled trial. Uncomplicated pregnancies between 28 0/7 and 36 6/7 weeks with a nonanomalous singleton fetus of women who did not smoke, use narcotics, or have prior experience with yoga were included. A computer-generated simple randomization sequence with a 1:1 allocation ratio was used to randomize participants into the yoga or control group. Women in the yoga group participated in a 1-time, 1 hour yoga class with a certified instructor who taught a predetermined yoga sequence. In the control group, each participant attended a 1-time, 1 hour PowerPoint presentation by an obstetrician on American Congress of Obstetricians and Gynecologists recommendations for exercise, nutrition, and obesity in pregnancy. All participants underwent pre- and postintervention testing, which consisted of umbilical and uterine artery Doppler ultrasound, nonstress testing, a biophysical profile, maternal blood pressure, and maternal heart rate. A board-certified maternal-fetal medicine specialist, at a different tertiary center, interpreted all nonstress tests and biophysical profile data and was blinded to group assignment and pre- or postintervention testing. The primary outcome was a change in umbilical artery Doppler systolic to diastolic ratio. Sample size calculations indicated 19 women per group would be sufficient to detect this difference in Doppler indices (alpha, 0.05; power, 80%). Data were analyzed using a repeated-measures analysis of variance, a χ(2), and a Fisher exact test. A value of P < .05 was considered significant., Results: Of the 52 women randomized, 46 (88%) completed the study. There was no clinically significant change in umbilical artery systolic to diastolic ratio (P = .34), pulsatility index (P = .53), or resistance index (P = .66) between the 2 groups before and after the intervention. Fetal and maternal heart rate, maternal blood pressure, and uterine artery Dopplers remained unchanged over time. When umbilical artery indices were individually compared with gestational age references, there was no difference between those who improved or worsened between the groups., Conclusion: There was no significant change in fetal blood flow acutely after performing yoga for the first time in pregnancy. Yoga can be recommended for low-risk women to begin during pregnancy., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Background: Lengthy microvascular procedures carry hypothermia risk, yet limited published data evaluate the overall impact of core temperature on patient and flap morbidity. Although hypothermia may contribute to complications, warming measures are challenged by conflicting reports of intraoperative hypothermia improving anastomotic patency., Methods: A retrospective review included all free flaps performed by plastic surgeons at an academic medical center from December 2005 to December 2010. Intraoperative core temperatures were measured by esophageal probe, and median values recorded over 5-minute intervals yielded a case mean (Tavg), maximum (Tmax), and nadir (Tmin). Outcomes included flap failure, pedicle thrombosis, recipient site infection and complications associated with patient, and flap morbidity. Analysis used Student t test, Fisher exact test, Probit, and logistic regression., Results: Of 156 consecutive free tissue transfers, the median Tavg, Tmax, and Tmin were 36.5°C, 37.1°C, and 35.8°C, respectively. The flap failure rate was 7.7% (12/156) and pedicle thrombosis occurred in 9 (6%) cases. Core temperatures did not associate with overall flap failure or pedicle thrombosis but recipient site infection occurred in 21 (13%) patients who had significantly lower mean core temperatures (Tavg=36.0°C, P<0.01). Lower Tavg and Tmax significantly predicted recipient site infection (P<0.01 and P<0.05, respectively). Cut-point analysis revealed significant increases in recipient site infection risk at Tavg less than 37.0°C (P=0.026) and Tmin less than or equal to 34.5°C (P=0.020)., Conclusions: Intraoperative hypothermia posed significant risk of flap infection with no benefit to anastomotic patency in free tissue transfer.

Background: Prolonged operative time has been associated with increased postoperative complications and higher costs. Many academic centers have a designated day for didactics that cause cases to start 1 hour later. The purpose of this study is to analyze the late-start effect of microvascular breast reconstructions on operative duration., Methods: A retrospective review was performed on all patients who underwent abdomina-based free flap breast reconstruction from 2007 to 2011 and analyzed by those who had surgery on late-start versus normal-start days. Patient demographics, average operative time, postoperative complications, and individual surgeon effects were analyzed. A Student t-test was used to compare operative times with statistical significance set at p < 0.05. A multivariate regression analysis was performed to control for potential confounders., Results: A total of 272 patients underwent 461 free flap breast reconstructions. Twenty-one cases were performed on late-start days and 251 cases were performed on normal-start days. Patient demographics and complications were not statistically different between the groups. The average operative time for all reconstructions was 434.3 minutes. The average operative times were significantly longer for late-start days, 517.6 versus 427.3 minutes (p = 0.002). This was true for both unilateral and bilateral reconstructions (432.8 vs. 350.9 minutes, p = 0.05; 551.5 vs. 461.2 minutes, p = 0.007). There were no differences in perioperative complications and multivariate regression showed no statistically significant relationship of confounders to duration of surgery., Conclusion: Starting cases 1 hour later can increase operative times. Although outcomes were not affected, we recommend avoiding lengthy procedures on late-start days., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Objective: To compare the obstetric recommendations in American Congress of Obstetricians and Gynecologists (ACOG) practice bulletins (PB) with similar topics in UpToDate (UTD)., Study Design: We accessed all obstetric PB and cross-searched UTD (May 1999-May 2013). We analyzed only the PB which had corresponding UTD chapter with graded recommendations (level A-C). To assess comparability of recommendations for each obstetric topic, two maternal-fetal medicine (MFM) subspecialists categorized the statement as similar, dissimilar, or incomparable. Simple and weighted kappa statistics were calculated to assess agreement between the two raters., Results: We identified 46 ACOG obstetric PB and 86 UTD chapters. There were 50% fewer recommendations in UTD than in PB (181 vs. 365). The recommendations being categorized as level A, B, or C was significantly different (p < 0.001) for the two guidelines. While the overall concordance rate between the two MFM subspecialists was 83% regarding the recommendations for the same topic as similar, dissimilar, or incomparable, the agreement was moderate (kappa, 0.56; 95% confidence intervals, 0.48-0.65)., Conclusion: Though obstetricians have two sources for graded recommendations, incongruity among them may be a source of consternation. Congruent recommendations from ACOG and UTD could enhance compliance and potentially optimize outcomes., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous malignancy. Adjuvant radiation increases survival in advanced stages, but efficacy in stage I disease is unknown. A retrospective review included all patients treated for stage I MCC during a 15-year period at Vanderbilt University Medical Center. Among 42 patients, 26 (62%) had a negative sentinel lymph node biopsy (stage IA) and 16 (38%) had clinically negative lymph nodes (stage IB) at the time of resection. Analysis using Cox regression revealed that higher stage and absence of adjuvant radiation are associated with increased disease recurrence (hazard ratio, 6.29; P=0.003 and hazard ratio, 4.69; P=0.013, respectively). Controlling for stage, radiation therapy significantly increased disease-free survival among patients with stage IB disease (P=0.0026) in a log-rank test comparing Kaplan-Meier curves. These findings support adjuvant radiation therapy in stage IB MCC patients with clinically negative lymph nodes who do not undergo sentinel lymph node biopsy.

Objective: To compare composite maternal and neonatal morbidities (CMM, CNM) among nulliparous women with primary indications for caesarean section (CS) as acute clinical emergency (group I; ACE), non-reassuring fetal heart rate (group II) and arrest disorder (group III)., Design: A multicentre prospective study., Setting: Nineteen academic centres in the USA, with deliveries in 1999-2002., Population: Nulliparous women (n = 9829) that had CS., Methods: Nulliparous women undergoing CS for three categories of indications were compared using logistic regression model, adjusted for five variables., Main Outcome Measures: CMM was defined as the presence of any of the following: intrapartum or postpartum transfusion, uterine rupture, hysterectomy, cystotomy, ureteral or bowel injury or death; CNM was defined as the presence of any of the following: umbilical arterial pH <7.00, neonatal seizure, cardiac, hepatic, renal dysfunction, hypoxic ischaemic encephalopathy or neonatal death., Results: The primary reasons for CS were ACE in 1% (group I, n = 114) non-reassuring FHR in 29% (group II; n = 2822) and failed induction/dystocia in the remaining 70% (group III; n = 6893). The overall risks of CMM and CNM were 2.5% (95% confidence intervals, CI, 2.2-2.8%) and 1.9% (95% CI 1.7-2.2), respectively. The risk of CMM was higher in group I than in group II (RR 4.1, 95% CI 3.1, 5.3), and group III (RR 3.2, 95% CI 2.7, 3.7). The risk of CNM was also higher in group I than in group II (RR 2.8, 95% CI 2.3, 3.4) and group III (RR 14.1, 95% CI 10.7, 18.7)., Conclusions: Nulliparous women who have acute clinically emergent caesarean sections are at the highest risks of both composite maternal and neonatal morbidity and mortality., (© 2014 Royal College of Obstetricians and Gynaecologists.)

Background: This piece aims to examine the relationships between hollow viscus injury (HVI) and socioeconomic factors in determining outcomes. HVI has well-defined injury patterns with complex postoperative convalescence and morbidity, representing an ideal focus for identifying potential disparities among a homogeneous injury population., Materials and Methods: A retrospective review included patients admitted to a level I trauma center with HVI from 2000-2009, as identified in the Trauma Registry of the American College of Surgeons. Patients with concomitant significant solid organ or vasculature injury were excluded. US Census (2000) median household income by zip code was used as socioeconomic proxy. Demographic and injury-related variables were also included. Endpoints were mortality and outcomes associated with HVI morbidity., Results: A total of 933 patients with HVI were identified and 256 met inclusion criteria. There were 23 deaths (9.0%), and mortality was not associated with race, gender, income, or payer source. However, lower median household income was significantly associated with longer intervals to ostomy takedown (P = 0.032). Additionally, private payers had significantly lower rates of anastomotic leak (0% [0/73] versus 7.1% [13/183], P = 0.019) and fascial dehiscence (5.5% [4/73] versus 16.9% [31/183], P = 0.016), while self-payers had significantly higher rates of abscess formation, both overall (24% [24/100] versus 10.2% [16/156], P = 0.004) and among penetrating injuries (27.4% [23/84] versus 13.6% [12/88], P = 0.036)., Conclusions: Socioeconomic status may not impact overall mortality among trauma patients with hollow viscus injuries, but private insurance appears to be protective of morbidity related to anastomotic leak, fascial dehiscence, and abscess formation. This supports that socioeconomic disparity may exist within long-term outcomes, particularly regarding payer source., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Background: Helicopter transport (HT) is necessary in the management of civilian trauma; however, its significant expense underscores the need to minimize overuse and inefficiency. Our objective was to determine whether on-scene physiologic criteria predict appropriate triage in HT trauma patients., Methods: We performed a retrospective review of patients flown from the injury scene to the emergency department of a level 1 trauma center by a university HT service from January 2006 to December 2010. Demographics, mechanism of injury, scene revised trauma score (RTS), travel distance, trauma alert level, payer status, emergency department and hospital disposition, and injury severity scores were queried from the electronic medical record and Trauma Registry of the American College of Surgeons with similar data on patients admitted because of trauma by ground transport for comparison. Proper triage criteria were defined through by the American College of Surgeons Committee on Trauma., Results: We identified 2522 HT patients. Of these, 1491 (59%) were properly triaged and 1031 (41%) were overtriaged. Univariate analysis revealed that the mean scene RTS was significantly higher for over- versus proper triage (7.68 ± 0.67 and 6.97 ± 1.57 respectively, P < 0.001). Neither the scene RTS nor travel distance predicted the triage criteria in a regression model (odds ratio 0.37, 95% confidence interval 0.16-0.85, and odds ratio 0.67, 95% confidence interval 0.60-0.74, respectively). Compared with ground transport, admitted HT patients had significantly more blunt trauma, lower scene RTSs, higher injury severity scores, more intensive care unit and ventilator days, a longer length of stay, and a greater travel distance and were more likely to be intubated (P < 0.001)., Conclusions: The physiological criteria did not predict the triage status in HT trauma patients. Although >40% of HT patients were overtriaged, they were more severely injured and required greater institutional resources than did the ground transport patients. Overtriage by a helicopter transport program might be appropriate., (Copyright © 2013 Elsevier Inc. All rights reserved.)

Hypertension affects 10% of pregnancies, many with underlying chronic hypertension, and approximately 1-2% will undergo a hypertensive crisis at some point during their lives. Hypertensive crisis includes hypertensive urgency and emergency; the American College of Obstetricians and Gynecologists describes a hypertensive emergency in pregnancy as persistent (lasting 15 min or more), acute-onset, severe hypertension, defined as systolic BP greater than 160 mmHg or diastolic BP >110 mmHg in the setting of pre-eclampsia or eclampsia. Pregnancy may be complicated by hypertensive crisis, with lower blood pressure threshold for end-organ damage than non-pregnant patients. Maternal assessment should include a thorough history. Fetal assessment should include heart rate tracing, ultrasound for growth and amniotic assessment, and Doppler evaluation if growth restriction is suspected. Initial management of hypertensive emergency (systolic BP >160 mmHg or diastolic BP >110 mmHg in the setting of pre-eclampsia or eclampsia) generally includes the rapid reduction of blood pressure through the use of intravenous antihypertensive medications, with goal systolic blood pressure between 140 mmHg and 150 mmHg and diastolic pressure between 90 mmHg and 100 mmHg. First-line intravenous drugs include labetalol and hydralazine, but other agents may be used, including esmolol, nicardipine, nifedipine, and, as a last resort, sodium nitroprusside. Among patients with hypertensive urgency, slower blood pressure reduction can be provided with oral agents. The objective of this article is to review the current understanding, diagnosis, and management of hypertensive crisis during pregnancy and the postpartum period., (Copyright © 2013 Elsevier Inc.

The late pre-Hispanic period in the US Southwest (A.D. 1200-1450) was characterized by large-scale demographic changes, including long-distance migration and population aggregation. To reconstruct how these processes reshaped social networks, we compiled a comprehensive artifact database from major sites dating to this interval in the western Southwest. We combine social network analysis with geographic information systems approaches to reconstruct network dynamics over 250 y. We show how social networks were transformed across the region at previously undocumented spatial, temporal, and social scales. Using well-dated decorated ceramics, we track changes in network topology at 50-y intervals to show a dramatic shift in network density and settlement centrality from the northern to the southern Southwest after A.D. 1300. Both obsidian sourcing and ceramic data demonstrate that long-distance network relationships also shifted from north to south after migration. Surprisingly, social distance does not always correlate with spatial distance because of the presence of network relationships spanning long geographic distances. Our research shows how a large network in the southern Southwest grew and then collapsed, whereas networks became more fragmented in the northern Southwest but persisted. The study also illustrates how formal social network analysis may be applied to large-scale databases of material culture to illustrate multigenerational changes in network structure.

Objective: The objective was to determine the rate of neonatal brachial plexus palsy (NBPP) among women with vaginal birth after cesarean delivery (VBAC) and to compare the peripartum characteristics with control subjects., Study Design: The Maternal-Fetal Medicine Unit cesarean registry data were used to identify nonanomalous singleton pregnancies with VBAC and NBPP at gestational age of ≥37 weeks (term) and 4 control subjects (matched for gestational age and diabetes mellitus status but without brachial injury). Odds ratio (OR) and 95% confidence intervals (CIs) were calculated., Results: Among 11,313 VBACs at term, there were 23 women with NBPP (rate of 2.0/1000 women). Newborn infants with NBPP, compared with control infants, were significantly more likely to weigh ≥4000 g (48% vs 10%, respectively; OR, 8.45; 95% CI, 2.58-28.44) and to require admission to the neonatal intensive care unit (30% vs 13%; OR, 12.98; 95% CI, 2.61-72.18)., Conclusion: Women who desire VBAC should be informed about the low rate of NBPP and, if eligible, encouraged to have a trial of labor after cesarean delivery., (Copyright © 2013 Mosby, Inc.

Early free flap coverage in lower extremity trauma is a practice largely supported by research that may be outdated and is frequently impractical due to logistics, resuscitation efforts, and associated injuries. Our objective was to re-evaluate this paradigm to determine whether reconstructive timing impacts outcome in modern clinical practice. We reviewed 60 free flaps for traumatic lower extremity coverage from December 2005 to December 2010 by the plastic surgery service at an academic medical center. All reconstructions were >72-hours from injury, spanning from 3 days to 2.2 years. The overall failure rate was 13.3% (8/60). Statistical analysis yielded no significant associations between reconstructive timing and flap failure or morbidity, although there was a trend toward fewer failures among latest reconstructions (>91 days) compared to within 30 days (P = 0.053). These findings support that delays may be safely utilized to allow patient and wound optimization without negatively impacting outcomes in free tissue transfer., (Copyright © 2012 Wiley Periodicals, Inc.)

Evidence-based guidelines regarding vaginal birth after cesarean from 3 countries (United States, Canada, and United Kingdom) were reviewed. The similarities in the 3 national guidelines (trial of labor after 1 previous cesarean, informed consent, delivery facility and available resources, epidural analgesia, continuous fetal monitoring, and induction and augmentation of labor) are understandable. Differences in recommendations (uterine rupture risk, success rate, intrauterine pressure catheter, and mechanical cervical ripening) are not explained. The likelihood of recommendations being categorized as level A differed: United States, 27% (3/11); Canada, 32% (6/19); and United Kingdom, 0% (0/17). Only 6 publications were cited by all 3 guidelines.

Patients undergoing microvascular reconstruction are often anemic from a combination of iatrogenic hemodilution and acute blood losses. No major clinical study describes the impact of preoperative anemia on free flap morbidity. The plastic surgery service at a high-volume academic center performed 156 free flaps among 147 patients from December 2005 to December 2010. One hundred thirty-two had a preoperative hemoglobin (Hb) or hematocrit (Hct), with mean values of 11.8±2.4 g/dL and 35.2%±7.0%, respectively. The overall failure rate was 9% (12/132), primarily from vascular thrombosis (6/12). Through logistic regression analysis, Hb and Hct were significant predictors of flap failure (P<0.005) and vascular thrombosis (P<0.05). Fisher exact test revealed a significant increase in failure risk at Hct level less than 30% (Hb<10 g/dL) (relative risk, 4.76, P=0.006), and probit analysis demonstrated an exposure-response relationship to decreased Hct level (P<0.005). These findings support that preoperative anemia could significantly impact free flap morbidity.

Evidence-based guidelines regarding intrapartum fetal surveillance from three countries (United States, Canada, and Australia/New Zealand) were reviewed. The similarities in the three national guidelines (purported etiology, management of periodic changes, and intermittent auscultation for low-risk women) are understandable. Differences in recommendations (role of fetal admission test, amnioinfusion for variable decelerations, scalp pH, umbilical arterial acid-base status, and education in interpretation of fetal heart tracing) are not explained. The likelihood of recommendations being categorized as level A differed for the countries: United States, 41% (7/17); Canada, 18% (3/17); and Australia and New Zealand, 17% (2/12). Only one publication was cited by all three guidelines. To avoid confusion and possibly enhance their quality, national guidelines should acknowledge the presence of others on the same topic, and if there are differences then provide explanations for dissimilarities., (Copyright © 2012 by Thieme Medical Publishers)

Objective: We sought to compare cognitive functioning in children born with birthweight <3% vs ≥3% for gestational age (GA) between 9 months and kindergarten., Study Design: Nonanomalous singletons from the Early Childhood Longitudinal Study-Birth Cohort were included. Associations between weight for GA and cognitive functioning were examined using a series of confounder-adjusted general linear models., Results: Of 3633 cohorts, 585 (16%) were <3% for GA. At 9 months, cognitive performance of newborns <3% was about 12 percentile points lower than their normal counterparts (P < .001). By 2 years, however, no significant cognitive differences between these groups were observed (P = .668). Academic performance at preschool age (around 3.5 years) was not different for reading (P = .245) or math (P = .880), nor different at kindergarten age., Conclusion: Newborns <3% for GA exhibit catch-up cognitive functioning by 2 years, with relatively no decrements in academic functioning observed by kindergarten., (Copyright © 2012 Mosby, Inc.

The purpose of the review article is to determine if prolonged (≥48 hour) tocolytics with symptomatic preterm placenta previa improves perinatal outcome. OVID MEDLINE and Cochrane Databases were searched from January 1950 to January 2009. Odds ratio (OR) and 95% confidence intervals (CI) were calculated. We identified two retrospective studies ( N = 217) and one randomized clinical trial (RCT; N = 60), and they were analyzed separately. Results of the RCT indicated that pregnancy is prolonged for more than 7 days with continued tocolytics (OR 3.10, 95% CI 1.38 to 6.96) but combined results of two retrospective studies did not confirm the prolongation (OR 1.19, 95% CI 0.63 to 2.28). The RCT was inadequately compliant with Consolidated Standards of Reporting Trials statement. While awaiting an appropriately designed RCT to determine the duration of tocolytics with placenta previa and preterm labor, it should be limited to 48 hours., (Thieme Medical Publishers.)
