Published: April 2018

Objective:
To describe the results of a thorough evaluation in a large series of patients with an enlarged vestibular aqueduct (EVA), focusing on vestibular manifestations with etiological considerations.

Study Design:
Retrospective chart review of patients with EVA.

Setting:
Tertiary referral center.

Patients:
A total of 22 EVA patients with a median age of 8 years (6 mo–35 yr) who underwent both audiovestibular and radiologic examinations.

Main Outcome Measures:
Patient demographics, radiologic findings, audiologic results, vestibular symptoms, findings of neurotologic examinations, and laboratory evaluations were collected and analyzed. Standard descriptive statistics were used to summarize patient characteristics. Subjects who had a history of vertigo attack were categorized as “vestibulopathy group,” while subjects without any history of vertigo as “non-vestibulopathy group.”

Results:
Of the 41 ears included, 37 (90.2%) had hearing loss on initial audiometric evaluations. Among the 22 patients, 14 (63.6%) complained of dizziness. Of the 14 vertiginous patients, seven had recurrent episodes, five had a history of single attack, and two presented with postural imbalances. There were no significant differences between vestibulopathy and non-vestibulopathy groups with regard to the relationship between the development of vestibular symptoms and aqueductal size, hearing threshold, or age at first visit. Four of the 22 (18.2%) patients developed secondary benign paroxysmal positional vertigo (BPPV) and all patients complained of simultaneous decreases in hearing.

Conclusions:
Our results demonstrate that patients may develop vestibular symptoms during their clinical course, and all patients with an enlarged vestibular aqueduct should be cautioned regarding the potential development of vestibular pathology. Moreover, the non-negligible incidence of secondary BPPV mandates positional tests when evaluating EVA patients with vertigo.

Published: April 2018

Background and Aims:
The standard of care for managing pancreaticobiliary disease in altered Roux-en-Y gastric bypass patients is laparoscopy-assisted endoscopic retrograde cholangiopancreatography (LA-ERCP), but is limited by cost and adverse events. Recently a minimally invasive, completely endoscopic approach using endoscopic ultrasound (EUS) directed transgastric ERCP (EDGE) has been described. We aim to compare EDGE to LA-ERCP in this study.

Methods:
Patients from May 2005 to June 2017 with Roux-en-Y gastric bypass anatomy having undergone LA-ERCP or EDGE at 4 tertiary centers were captured in a registry. Patient demographics, procedural details, and clinical outcomes were measured for each group.

Results:
Seventy-two patients (n=29 EDGE, n=43 LA-ERCP) were included in this study. There was no significant difference in the technical success of EDGE gastrogastric fistula (96.5%) versus LA-gastrostomy creation (100%). The success rate of achieving therapeutic ERCP (EDGE 96.5% vs. LA-ERCP 97.7%) and number of ERCP (EDGE 1.2 vs. LA-ERCP 1.02) needed to achieve clinical resolution was similar between both groups. Adverse event rate for EDGE, 24% (7/29) and LA-ERCP, 19% (8/43) was similar. The total procedure time (73 vs. 184 min) and length of hospital stay (0.8 vs. 2.65 d) was significantly shorter for EDGE compared to LA-ERCP. The overall weight change after EDGE was −6.6 lbs at an average 28-week follow-up.

Conclusions:
This study suggests that the EDGE procedure has similar technical success and adverse events compared with LA-ERCP with the benefit of significantly shorter procedure times and hospital stay. EDGE may offer a minimally invasive, effective option, with less resource utilization, and without significant weight gain.

Published: April 2018

Background:
Electronic health records provide the opportunity to assess system-wide quality measures. Veterans Affairs Pharmacy Benefits Management Center for Medication Safety uses medication use evaluation (MUE) through manual review of the electronic health records.

Objective:
To compare an electronic MUE approach versus human/manual review for extraction of antibiotic use (choice and duration) and severity metrics.

Research Design:
Retrospective.

Subjects:
Hospitalizations for uncomplicated pneumonia occurring during 2013 at 30 Veterans Affairs facilities.

Measures:
We compared summary statistics, individual hospitalization-level agreement, facility-level consistency, and patterns of variation between electronic and manual MUE for initial severity, antibiotic choice, daily clinical stability, and antibiotic duration.

Results:
Among 2004 hospitalizations, electronic and manual abstraction methods showed high individual hospitalization-level agreement for initial severity measures (agreement=86%–98%, κ=0.5–0.82), antibiotic choice (agreement=89%–100%, κ=0.70–0.94), and facility-level consistency for empiric antibiotic choice (anti-MRSA r=0.97, P<0.001; antipseudomonal r=0.95, P<0.001) and therapy duration (r=0.77, P<0.001) but lower facility-level consistency for days to clinical stability (r=0.52, P=0.006) or excessive duration of therapy (r=0.55, P=0.005). Both methods identified widespread facility-level variation in antibiotic choice, but we found additional variation in manual estimation of excessive antibiotic duration and initial illness severity.

Conclusions:
Electronic and manual MUE agreed well for illness severity, antibiotic choice, and duration of therapy in pneumonia at both the individual and facility levels. Manual MUE showed additional reviewer-level variation in estimation of initial illness severity and excessive antibiotic use. Electronic MUE allows for reliable, scalable tracking of national patterns of antimicrobial use, enabling the examination of system-wide interventions to improve quality.

Published: April 2018

Background:
Cerebral sinus venous thrombosis (CSVT) is a rare cerebrovascular disease that may be life-threatening, especially in children.

Objective:
The purpose of this study was to assess the clinical presentation, radiologic imaging, underlying conditions, treatment, and outcomes of children with CSVT.

Patients and Methods:
In total, 23 consecutive children aged between 1 month to 18 years with CSVT, who were followed-up in Erciyes University Children’s Hospital, were retrospectively enrolled in the study from January 2000 to December 2016.

Results:
The median age of the 23 children (13 female patients, 10 male patients) at initial diagnosis was 60 months (1 to 204 mo). The most common clinical manifestation was headache/irritability (n=9). The most common site of the CSVT was the transverse sinus (n=16). The most common prothrombotic risk factor was protein C deficiency (n=4). Underlying risk factors were detected in 15 patients. Genetic risk factors such as protein C deficiency, infections, trauma, malignancies, autoimmune hemolytic anemia, neurometabolic disorders, asphyxia, and cardiac malformations were common risk factors. Six children died. Multiple sinus involvement and parenchymal hemorrhages were seen in 4 and in 3 of the 6 children who died, respectively.

Conclusions:
Protein C deficiency seemed to be relatively high in the presented children. Multiple sinus involvement and additional parenchymal hemorrhages represent poor prognostic features.

Published: April 2018

Background:Hemoglobin (Hb) Constant Spring is an alpha-globin gene variant due to a mutation of the stop codon resulting in the elongation of the encoded polypeptide from 141 to 172 amino acid residues. Patients with homozygous Hb Constant Spring are usually mildly anemic.Methods:We retrospectively describe clinical manifestations, diagnosis, laboratory investigations, treatment, and associated findings in pediatric patients with homozygous Hb Constant Spring followed-up at Srinagarind Hospital.Results:Sixteen pediatric cases (5 males and 11 females) were diagnosed in utero (N=6) or postnatal (n=10). Eleven cases were diagnosed with homozygous Hb Constant Spring, 4 with homozygous Hb Constant Spring with heterozygous Hb E, and 1 with homozygous Hb Constant Spring with homozygous Hb E. Three cases were delivered preterm. Six patients had low birth weights. Clinical manifestations included fetal anemia in 6 cases, hepatomegaly in 1 case, hepatosplenomegaly in 2 cases, splenomegaly in 1 case. Twelve cases exhibited early neonatal jaundice, 9 of which required phototherapy. Six cases received red cell transfusions; 1 (3), >1 (3). After the first few months of life, almost all patients had mild microcytic hypochromic anemia and an increased reticulocyte count with a wide red cell distribution (RDW), but no longer required red cell transfusion. At 1 to 2 years of age, some patients still had mild microcytic hypochromic anemia and some had normocytic hypochromic anemia with Hb around 10 g/dL, increased reticulocyte count and wide RDW. Associated findings included hypothyroidism (2), congenital heart diseases (4), genitourinary abnormalities (3), gastrointestinal abnormalities (2), and developmental delay (1).Summary:Pediatric patients with homozygous Hb Constant Spring developed severe anemia in utero and up to the age of 2 to 3 months postnatal, requiring blood transfusions. Subsequently, their anemia was mild with no evidence of hepatosplenomegaly. Their Hb level was above 9 g/dL with hypochromic microcytic blood pictures as well as wide RDW. Blood transfusions have not been necessary since then.
Glucose Homeostasis Markers in Beta-Thalassemia
Authors: Gomber Sunil , Bagaria Anjali , Madhu Sri V. , Dewan Pooja 
Published: April 2018

Background:
Glycosylated hemoglobin (HbA1c) has been a well-recognized marker of glucose homeostasis among thalassemics. Recently some studies have proposed the role of fructosamine as a better marker as compared with HbA1c. Hence, the study was carried out to find out which marker holds promise among Indian beta-thalassemic children.

Methods:
In this case-control study, 60 diagnosed cases of beta-thalassemia major and equal number of normal controls who were ≥8 years of age were enrolled. HbA1c, fructosamine, and fasting insulin levels were measured in all. Oral glucose tolerance test was done as a gold standard and the measured parameters were compared.

Results:
HbA1c was significantly higher in cases (7.10% [±0.47%]) than in controls (5.15% [±0.19%]) (P<0.001). Thalassemics with abnormal glucose tolerance had higher HbA1c level (7.34% [±0.57%]) than those with normal glucose tolerance (7.05% [±0.43%]) (P=0.05). Insulin resistance was noticed among thalassemics with abnormal glucose tolerance as compared with their normal counterparts (P=0.04). No significant difference was found in fructosamine levels between cases (239.80 [±31.80] μmol/L) and controls (234.10 [±21.34] μmol/L) (P=0.25) or between thalassemics with abnormal glucose tolerance (243.92 [±21.94] μmol/L) and their normal counterparts (238.77 [±33.93] μmol/L) (P=0.62).

Conclusions:
The use of HbA1c as a diagnostic marker for diabetes in hemolytic anemias has to be done with caution as its baseline values are higher in them. Despite this finding, HbA1c continues to be a good marker for worsening glucose homeostasis in thalassemics as higher values were found in thalassemics with abnormal glucose tolerance compared with their normal counterparts. The present study did not find any relationship of fructosamine levels with impaired glucose tolerance in beta-thalassemia.
Characteristics of Medical Professional Liability Claims in Pediatric Orthopedics
Authors: Burns Jessica , Shrader M. Wade , Boan Carla , Belthur Mohan 
Published: April 2018

Objectives
Medical malpractice is burdensome to the U.S. healthcare system. The following is an epidemiological analysis of the closed medical professional liability (MPL) claims in pediatric orthopedics using data maintained by the Physician Insurers Association of America.

Methods
The Physician Insurers Association of America registry of MPL claims from 1985 to 2013 for all specialties included 286,021 closed claims in the United States. All closed MPL claims for orthopedic surgery in patients younger than 18 years were retrospectively reviewed (N = 2,671). The error categories, result of the claim, the most common procedures, severity of injury, and the most common presenting and resultant medical conditions were reported with the paid-to-close ratios, average indemnity payment, and average cost of litigation. The pediatric orthopedic population was compared with all orthopedics. The data were adjusted for inflation and trended for the 29-year period.

Results
Of the 2671 pediatric orthopedic claims, 881 resulted in a payment and the average indemnity was U.S. $317,574 with adjustment for inflation - significantly higher than for all of orthopedics at U.S. $268,817 (P = 0.0013). The paid-to-close ratio was 33.0%, compared with 28.7% for all of orthopedics (P = 0.023).

Conclusions
Costs to defend individual medical malpractice claims and the average indemnity payment per claim have both increased over time, and pediatric (versus adult) orthopedic claims are more likely to result in payment and result in a higher payment. Knowledge of the details of liability claims should assist practicing general and pediatric orthopedic surgeons in improving patient safety and quality of care, reducing patient injury, and reducing the incidence of MPL claims.

Published: April 2018

Objectives
Primary Health Care Corporation (PHCC) is the public primary health care provider in Qatar. Having a patient safety culture (PSC) is the keystone to enabling a continuous process to improve the quality of services and to reduce errors. The objective of this study was to assess the impact of accreditation, quality improvement trainings, and patient safety (PS) trainings on the improvement of the PSC at the PHCC in Qatar.

Methods
The Medical Office Survey on Patient Safety Culture from the Agency for Healthcare Research and Quality was used in 2012 and 2015 to assess the culture of PS and health care quality in the 21 health centers. The results of the two surveys were compared using the χ2 test. A P value of less than 0.05 was considered significant.

Results
Out of 2689 staff working in the 21 health centers, 1810 (67.3%) completed the survey in 2012, and 2616 (70.0%) of 3735 completed the survey in 2015. The comparison between 2012 and 2015 survey’s results showed a statistically significant improvement for all the 10 dimensions (P < 0.05). Although a statistically significant difference was observed between 2012 and 2015 results for work pressure and pace, three of the four questions of the work pressure and pace dimension presented nonsignificant differences.

Conclusions
The survey was a good tool to raise awareness on PS and quality issues at PHCC. There is evidence that the implementation of accreditation program, the quality improvement trainings, and PS trainings helped the organization improve its PS culture.
Kinematic Magnetic Resonance Imaging of the Thorax Using 2-Dimensional Balanced Subsecond Steady-state Free Precession Sequence During Forced Breathing in Comparison With Spirometry
Authors: Tanimoto Daigo , Ito Katsuyoshi , Higashi Hiroki , Yamamoto Akira , Kanki Akihiko , Yasokawa Kazuya , Tamada Tsutomu 
Published: April 2018

Purpose:
The purpose of this article was to investigate the feasibility of kinematic magnetic resonance imaging (MRI) during forced breathing for the assessment of thoracic and diaphragmatic movement and to compare the results of MRI and spirometry to determine the MRI parameters that are predominantly associated with pulmonary function.

Materials and Methods:
Forty-nine healthy volunteers who underwent kinematic MRI using 2-dimensional balanced subsecond steady-state free precession sequence during forced breathing were included. Several items on the MRI were measured and calculated: these were anteroposterior diameter (APD) of the thorax, APD1, ΔAPD, and cross-sectional area (CSA) of the lung field. The results were compared with the results of spirometry.

Results:
In the comparison between the spirometry results and the MRI kinematic changes, CSA1, ΔCSA, and CSA1% were most significantly correlated with forced expiratory volume in 1 second (right: P<0.001, r=0.814; left: P<0.001, r=0.759); vital capacity (right: P<0.001, r
=0.797; left: P<0.001, r=0.780); and forced expiratory volume% in 1 second (right: P<0.001, r=0.530; left: P<0.001, r=0.518), respectively. The APD1 values in the upper position were significantly larger than those in the middle (right: P<0.001; left: P<0.001) and lower (right: P<0.001; left: P<0.001) positions. The ΔAPD values in the upper position were also significantly larger than those in the middle (right: P<0.001; left: P<0.001) and lower (right: P<0.001; left: P<0.001) positions.

Conclusion:
Kinematic MRI with 2-dimensional balanced subsecond steady-state free precession can be used to assess thoracic and diaphragmatic movement during forced breathing. The dynamic changes in CSA correlated well with the results of spirometry.
Comparison of Functional Results After Cross-Face Nerve Graft-, Spinal Accessory Nerve-, and Masseter Nerve-Innervated Gracilis for Facial Paralysis Reconstruction
Authors: Chuang David Chwei-Chin , Lu Johnny Chuieng-Yi , Chang Tommy Nai-Jen , Laurence Vincent G. 
Published: April 2018

Background
Using functioning free muscle transplantation (FFMT) for facial paralysis and postparalysis facial synkinesis reconstruction is our preferred technique. Gracilis was the first choice of muscle. Three motor neurotizers: cross-face nerve graft (CFNG), spinal accessory nerve (XI) and masseter nerve (V3) have been used as neurotizers for different indications.

Methods
A total of 362 cases of facial reanimation with FFMT were performed between 1986 and 2015. Of these, 350 patients with 361 FFMT were enrolled: 272 (78%) patients were treated by CFNG-gracilis, 56 (15%) by XI-gracilis, and 22 (6%) by V3-gracilis. Smile excursion score, cortical adaptation stage with tickle test for spontaneous smile, facial synkinesis, satisfaction score by questionnaire, and functional facial grading were used for outcome assessment.

Results
The CFNG-gracilis in a 2-stage procedure achieved most natural and spontaneous smile when longer observation (≥2 years) was followed. The single-stage procedure using the XI-gracilis has proven a good alternative. V3-gracilis provided high smile excursion score in the shortest rehabilitation period, but never obtained spontaneous smile.

Conclusions
The CFNG-gracilis remains our first choice for facial paralysis reconstruction which can achieve natural and spontaneous smile. XI- or V3-gracilis can be selected as a save procedure when CFNG-gracilis fails. The V3-gracilis is indicated in some specific conditions, such as bilateral Möbius syndrome, older patients (age, >70 years), or patients with malignant disease.
TEG Lysis Shutdown Represents Coagulopathy in Bleeding Trauma Patients: Analysis of the PROPPR Cohort

Published: April 2018

ABSTRACT

Background:
Thrombelastography (TEG) fibrinolysis shutdown after trauma is associated with increased mortality due to hypercoagulability-associated organ failure. However, a lack of mechanistic data has precluded the development of novel interventions to treat shutdown.

Objectives:
To define the pathophysiology of TEG shutdown in severely injured, bleeding patients through secondary analysis of the PROPPR trial.

Methods:
Fibrinolysis was characterized in PROPPR subjects using admission TEG lysis at 30 min (LY30) or plasmin-antiplasmin (PAP) levels. LY30 categories were low (<0.9%), moderate (0.9–2.9%), or high (≥ 3%). PAP was classified as low (<1,500 μg/L), moderate (1,500–20,000 μg/L), or high (>20,000 μg/L). Demographics, outcomes, admission TEG values, platelet count and function, standard coagulation tests, and coagulation proteins were compared.

Results:
Five hundred forty-seven patients had TEG data and 549 patients had PAP data available. Low LY30 was associated with reduced platelet count and aggregation, poorer TEG clot formation, prolonged clotting times, and reduced fibrinogen and alpha2 antiplasmin. Compared to moderate PAP, low PAP subjects had similar platelet parameters, TEG values, fibrinogen, and alpha2 antiplasmin, but reduced tPA, and elevated PAI-1. D-Dimer values increased as PAP increased, however patients with low LY30 had elevated D-Dimer compared with moderate LY30 patients. Most low LY30 deaths were due to TBI (45%) and hemorrhage (42%) versus one of each cause (TBI, hemorrhage, MOF) in low PAP patients.

Conclusions:
Low TEG LY30 does not reflect shutdown of enzymatic fibrinolysis with hypercoagulability, but rather a coagulopathic state of moderate fibrinolysis with fibrinogen consumption and platelet dysfunction that is associated with poor outcomes.
