Anesthesia in Enhanced Recovery Pathways for Hip and Knee Arthroplasty: Where Is the Evidence?
Prohemostatic Activity of Factor X in Combination With Activated Factor VII in Dilutional Coagulopathy
BACKGROUND: Recombinant activated factor VII (rFVIIa) concentrate reduces allogeneic blood transfusions, but it may increase thromboembolic complications in complex cardiac surgery. The mixture of activated factor VII (FVIIa) and factor X (FX) (FVIIa/FX) (FVIIa:FX = 1:10) is a novel bypassing agent for hemophilia patients. We hypothesized that the combination of FX and FVIIa could improve thrombin generation (TG) in acquired multifactorial coagulation defects such as seen in cardiac surgery and conducted in vitro evaluation of FVIIa/FX in parallel with other coagulation factor concentrates using in vitro and in vivo diluted plasma samples. METHODS: Plasma samples were collected from 9 healthy volunteers and 12 cardiac surgical patients. We measured TG (Thrombinoscope) using in vitro 50% dilution plasma and in vivo dilution plasma after cardiopulmonary bypass, in parallel with thromboelastometry (ROTEM) and standard coagulation assays. In vitro additions of FVIIa/FX (0.35, 0.7, and 1.4 μg/mL, based on the FVIIa level), rFVIIa (1.4, 2.8, and 6.4 μg/mL), prothrombin complex concentrate (0.3 international unit), and 20% plasma replacement were evaluated. RESULTS: In diluted plasma, the addition of either FVIIa/FX or rFVIIa shortened the lag time and increased the peak TG, but the effect in lag time of FVIIa/FX at 0.35 μg/mL was more extensive than rFVIIa at 6.4 μg/mL. Prothrombin complex concentrate increased peak TG by increasing the prothrombin level but failed to shorten the lag time. No improvement in any of the TG variables was observed after 20% volume replacement with plasma. The addition of factor concentrates normalized prothrombin time/international normalized ratio but not with plasma replacement. In cardiac patients, similar patterns were observed on TG in post–cardiopulmonary bypass samples. FVIIa/FX shortened clotting time (CT) in a concentration-dependent manner on CT on thromboelastometry. Plasma replacement did not improve CT, but a combination of plasma and FVIIa/FX (0.35 μg/mL) more effectively shortened CT than FVIIa/FX alone. CONCLUSIONS: The combination of FVIIa and FX improved TG more efficiently than rFVIIa alone or plasma in dilutional coagulopathy models. The required FVIIa dose in FVIIa/FX was considerably lower than those reported during bypassing therapy in hemophilia patients (1.4–2.8 μg/mL). The combination of plasma could restore coagulation more efficiently compared to FVIIa/FX alone. Lesser FVIIa requirement to exert procoagulant activity may be favorable in terms of reducing systemic thromboembolic complications. Accepted for publication September 6, 2018.

Concepts for the Development of Anesthesia-Related Patient Decision Aids
Patient decision aids are educational tools used by health care providers to assist patients in choosing their treatment and care. The use of anesthesia-related patient decision aids can help practitioners provide patient-centered care by facilitating shared decision-making. The benefits of these aids have been well documented, yet a structured approach for developing patient decision aids in anesthesia has not been well established. Educating patients on various anesthesia-related options is paramount in their decision-making, yet accessible and validated resources are limited. In addition, many limitations exist with current patient decision aids that must be addressed. We have reviewed multiple processes for developing decision aids and have suggested a structured approach to their creation. We address the common limitations of current patient decision aids and provide improvements to the developmental process. Improvements include increasing patient input during development, thoroughly evaluating data included in the aids, and integrating a cyclic review of the aids before and after their use. Using the provided developmental process and checklist, anesthesia providers can create evidence-based patient decision aids in a standardized manner. It is important to evaluate decision aids and measure their decision quality, or patient-centeredness, to further improve them and maximize their effectiveness. Moving forward, development of proper metrics for patient participation and decision quality are required. Accepted for publication July 30, 2018. Funding: None.

Rapid Titration of Intravenous Treprostinil to Treat Severe Pulmonary Arterial Hypertension Postpartum: A Retrospective Observational Case Series Study
BACKGROUND: Pulmonary hypertension during pregnancy carries high mortality rate. The relatively long-acting, specific pulmonary vasodilator treprostinil has been used to improve survival in these parturients. Slow uptitration is performed in most cases, and rapid titration has not been reported in the postpartum period. METHODS: We retrospectively reviewed 17 pregnant patients with severe pulmonary arterial hypertension who were treated with intravenous treprostinil in our institution between 2014 and 2016. Patients' demographic characteristics, etiology, functional status, mode of delivery, anesthetic administration, medical therapy, echocardiographic and hemodynamic measurements, subsequent clinical course, and maternal–fetal outcomes were assessed. The a priori primary outcome is maternal mortality in this study. RESULTS: Rapid titration of intravenous treprostinil was initiated at 1.25 ng/kg/min and increased to effective dose of 10 ng/kg/min by 1.25–2.5 ng/kg/min every 3 hours. In the next 24 hours, we adjusted the dosage to a median maximum dose of 15 ng/kg/min (interquartile range, 15–20 ng/kg/min) over a median uptitration period of 34 hours (interquartile range, 24–41 hours) for 17 parturients with severe pulmonary hypertension. Treprostinil was weaned off by 0.50–1.25 ng/kg/min every 3 hours in 94.3 ± 42.4 hours. Fifteen patients survived to discharge, and only 2 patients died of pulmonary hypertensive crisis (maternal mortality rate, 11.7%). No treprostinil infusion-related postpartum complication was observed. CONCLUSIONS: Our experience suggested that rapid uptitration of intravenous treprostinil combined with oral sildenafil in the postpartum period may be a safe and effective approach for these very sick parturients with severe pulmonary hypertension.

Electronic Audit and Feedback With Positive Rewards Improve Anesthesia Provider Compliance With a Barcode-Based Drug Safety System
BACKGROUND: We implemented a previously described barcode-based drug safety system in all of our anesthetizing locations. Providers were instructed to scan the barcode on syringes using our Anesthesia Information Management System before drug administration, but the rate of provider adherence was low. We studied an implementation intervention intended to increase the rate of scanning. METHODS: Using our Anesthesia Information Management System and Smart Anesthesia Manager software, we quantified syringe drug administrations by anesthesia providers with and without barcode scanning. We use an anesthesia team model in which an attending anesthesiologist is paired with a certified registered nurse anesthetist (CRNA) or a resident. Our system identified the pair of providers associated with a particular drug administration, but did not distinguish which providers actually administered the drug. Therefore, the rate of barcode scanning for a particular case was assigned to both providers equally. A baseline rate of scanning was established over a period of 17 months. An audit and feedback intervention was then performed that consisted of monthly performance reports sent by email to individual providers along with coffee gift card awards for top performers. The coffee gift cards were awarded in only the first 2 months of the intervention, while the email performance reports continued on a monthly basis. The coffee card awards were made public. The monthly emails reported the individual provider's rank order of performance relative to other providers, but was otherwise anonymous. The baseline rate of scanning was compared to the rate of scanning after the intervention for a period of 7 months. RESULTS: From November 2014 to March 2017, we accumulated 60,197 cases performed by 88 attending anesthesiologists, 65 CRNAs, and 148 residents. The total number of syringe drug administrations was 653,355. Average scanning performance improved from 8.7% of syringe barcodes scanned during the baseline period from November 2014 to February 2016 to 64.4% scanned during the period September 2016 to March 2017 (P

Factor XI Deficiency: The Key Is Individualization
Prospective, Randomized Comparison of the i-gel and the Self-Pressurized air-Q Intubating Laryngeal Airway in Elderly Anesthetized Patients
BACKGROUND: Age-related changes in upper airway anatomy may affect the overall performance of supraglottic airways significantly. The clinical performance of the i-gel and the self-pressurized air-Q intubating laryngeal airways with noninflatable cuffs for elderly populations remains unknown, unlike in children. Thus, we performed a prospective, randomized comparison of these 2 supraglottic airways in elderly patients undergoing general anesthesia. METHODS: We recruited 100 patients, 65–90 years of age, who were scheduled for elective surgery under general anesthesia with muscle relaxation. The enrolled patients were allocated to the i-gel or self-pressurized air-Q group. We assessed oropharyngeal leak pressure as the primary outcome and fiberoptic view after placement and fixation of the airway and at 10 minutes after the initial assessment. The fiberoptic view was scored using a 5-point scale as follows: vocal cords not visible; vocal cords and anterior epiglottis visible, >50% visual obstruction of epiglottis to vocal cords; vocal cords and anterior epiglottis visible,

Clinical Use of the Pictorial Baxter Retching Faces Scale for the Measurement of Postoperative Nausea in Children
BACKGROUND: Because nausea is difficult to evaluate in children, vomiting is used as the objective clinical end point in managing pediatric postoperative nausea and vomiting and postdischarge nausea and vomiting (PDNV). The recently developed pictorial Baxter Retching Faces (BARF) scale has content, construct, and convergent validity in quantifying pediatric nausea intensity. We determined its clinical usefulness in assessing pediatric postoperative nausea and vomiting and PDNV, establishing the lowest age associated with consistently reliable use, the score at which patients identify a need for therapy, and the minimum clinically relevant change in scores, and examined its test–retest reliability. METHODS: We obtained subject ratings of the severity of their nausea using the BARF and visual analog scales in the preoperative, postanesthesia care unit and postdischarge phases. Changes in nausea were rated on a 5-point Likert scale, along with responses to queries of a need for rescue antiemetics at these time points. RESULTS: Children ≥6 years of age had a consistently reliable ability to use the BARF scale (132/132 [100%] vs 59/76 [77.6%] for children ≥6 and 6) in 13 (6.7%). Emesis occurred in 8 (4.1%). Rescue antiemetics were administered to 16 (8.3%), including 2 with severe emesis (≥3 episodes) but in only 2 of 11 (18.2%) with severe nausea without vomiting. PDNV was reported in 39 of the 99 who returned diaries (39.4%), with nausea in 34 (34.3%), severe nausea in 15 (15.2 %), and emesis in 16 (16.2%). CONCLUSIONS: The pictorial BARF scale is easy to use in the clinical setting by children ≥6 years of age, has a minimum clinically relevant difference of 1.47, with scores of 4 or higher associated with a patient-identified need for rescue antiemetics. Assessment of postoperative nausea by the BARF scale has shown that clinically significant nausea occurs frequently in children but is not always treated unless accompanied by vomiting.

Attenuation of Unevoked Mechanical and Cold Pain Hypersensitivities Associated With Experimental Neuropathy in Mice by Angiotensin II Type-2 Receptor Antagonism
Recent findings from a phase II clinical trial showed analgesic effects of an angiotensin II type-2 receptor (AT2R) antagonist in postherpetic neuralgia patients. This study aimed to investigate whether AT2R antagonism could provide effective analgesia in voluntary measures of unevoked/ongoing pain-like behaviors in mice with experimental neuropathy. Mice were subjected to spared nerve injury to induce neuropathy and tested in 2 operant behavioral tests to measure ongoing mechanical and cold pain hypersensitivities. Systemic administration of an AT2R antagonist provided effective analgesia in these behavioral measures of mechanical and cold pain in spared nerve injury mice, suggesting its effectiveness in neuropathic pain.

Improving outcomes in ambulatory anesthesia by identifying high risk patients
Purpose of review Currently, outcome data in ambulatory anesthesia are somewhat limited though results are quite good with low reported rates of mortality and major morbidity. As patient comorbidities and surgical invasiveness increase, identifying those patients at higher risk will help to focus quality improvement energy and research where most effective. Better data collection and analysis will refine patient and procedure selection and improve outcomes going forward. Recent findings Complications after ambulatory surgery are associated with age, higher American Society of Anesthesiologists physical status, obstructive sleep apnea, and obesity. Frailty has recently been linked to increased complications in ambulatory surgery as well. Newer ambulatory procedures such as spine and total joint arthroplasty require careful patient selection. Summary Identifying high-risk ambulatory patients can help facilitate development of a strategy to triage these patients, optimize their conditions prior to surgery, and manage their care and disposition postoperatively. Inpatient surgery or admission should be considered for higher risk patients having high invasive surgery. Correspondence to Michael T.

Pretarsal roll augmentation with dermal hyaluronic acid filler injection
Abstract
Pretarsal roll augmentation with dermal hyaluronic acid filler injection focuses on restoring pretarsal fullness. This study aimed to introduce a method of pretarsal roll augmentation with dermal hyaluronic acid filler injection and establish the level of difficulty, safety, and effectiveness of this method. Eighty female patients were enrolled in this study. Hyaluronic acid filler was used to perform pretarsal roll augmentation. Physician and patient satisfaction at 1 month and 4 months after surgery was investigated. The level of satisfaction was graded from points 1 to 5.

Improving outcomes in ambulatory anesthesia by identifying high risk patients
Purpose of review Currently, outcome data in ambulatory anesthesia are somewhat limited though results are quite good with low reported rates of mortality and major morbidity. As patient comorbidities and surgical invasiveness increase, identifying those patients at higher risk will help to focus quality improvement energy and research where most effective. Better data collection and analysis will refine patient and procedure selection and improve outcomes going forward. Recent findings Complications after ambulatory surgery are associated with age, higher American Society of Anesthesiologists physical status, obstructive sleep apnea, and obesity. Frailty has recently been linked to increased complications in ambulatory surgery as well. Newer ambulatory procedures such as spine and total joint arthroplasty require careful patient selection. Summary Identifying high-risk ambulatory patients can help facilitate development of a strategy to triage these patients, optimize their conditions prior to surgery, and manage their care and disposition postoperatively. Inpatient surgery or admission should be considered for higher risk patients having high invasive surgery. Correspondence to Michael T.

A Case of Diprosopus Tetraophthalmos: Ocular Findings and Surgical Treatment of Exposure Keratopathy
Diprosopus is a rare variation of conjoined twinning. In this report, ophthalmic findings in an infant with diprosopus tetraophthalmos are presented. A male infant who was born at 33 weeks of gestation to a nonconsanguineous 42-year-old mother and 47-year-old father was examined for orbital abnormalities. The infant had a large head, 2 faces, and 4 eyes, of which 2 were placed laterally and 2 were fused in the midline. In the laterally placed eyes, the pupils were unresponsive to light, and the optic discs were hypoplastic. In the fused eyes, the lower and upper eyelids were also fused, horizontally wide, vertically short, and immobile, resulting in a progressive exposure keratopathy. On the 33rd day of life, a modified total tarsorrhaphy was performed with the use of inhalational mask anesthesia. The patient died due to pneumonia and septicemia on the 45th day of life.

Nontraumatic Orbital Hemorrhage During Uncomplicated Labor
Socket Reconstruction With Bleomycin, Gentamicin, and Gelatin Sponges Following Eyelid-Sparing Orbital Exenteration for a Colobomatous Macrocyst in an Infant
Microphthalmia is defined by a globe axial length greater than or equal to 2 standard deviations below the age-adjusted mean and can occur as part of a broader syndrome. The presence of a colobomatous cyst with microphthalmia signifies failure of the embryonic neuroectodermal fissure to close appropriately during development of the globe, creating a protuberant globular appendage that inhibits normal growth and development of the eye itself. Cystic reaccumulation of fluid is common after aspiration or surgical removal. Here, the authors describe a case of a young boy with a colobomatous cyst who underwent eyelid-sparing orbital exenteration followed by reconstruction with absorbable gelatin sponge (Gelfoam, Pfizer, Inc.) and the chemotherapeutic agent bleomycin to promote scarring, achieving the equivalent of a biointegrated implant and facilitating satisfactory placement of an ocular prosthesis. A 2-year follow-up MRI revealed adequate volume in the posterior orbit. Accepted for publication August 23, 2018. All authors attest that they meet the current ICMJE criteria for Authorship.

Septic Cavernous Sinus Thrombosis Associated With Orbital Cellulitis: A Report of 6 Cases and Review of Literature
Purpose: To describe risk factors, clinical parameters, treatment, and prognosis for patients with septic cavernous sinus thrombosis presenting with orbital cellulitis. Methods: Retrospective case series of 6 patients identified with septic cavernous sinus thrombosis and orbital cellulitis confirmed by magnetic resonance imaging at a tertiary care center from January 1980 to December 2016. Medical records were reviewed for demographics, risk factors, symptoms, etiology, radiographic diagnosis, complications, treatments, and outcomes. In addition, a literature review was performed from 2005 to 2018, and 119 cases of septic cavernous sinus thrombosis confirmed by imaging were included for aggregate comparison. This study adheres to the tenets of the Declaration of Helsinki, and institutional review board approval was obtained. Results: All 6 cases presented with headache, fever, ocular motility deficit, periorbital edema, and proptosis. The primary source of infection included sinusitis (n = 4) and bacteremia (n = 2). Identified microorganisms included methicillin resistant Staphylococcus aureus (n = 3) and Streptococcus anginosus (n = 1). All cases were treated with broad-spectrum intravenous antibiotics and anticoagulation, and one case underwent endoscopic sinus surgery. The mean time between initial presentation to diagnosis of cavernous sinus thrombosis was 2.8 days, and the average length of hospital admission was 21 days. The mortality rate was 0%, but 4 cases were discharged with neurological deficits including vision loss (n = 1) and ocular motility disturbance (n = 3). Literature review produced an additional 119 cases. Conclusions: Early diagnostic imaging with contrast-enhanced CT or MRI should be initiated in patients with risk factors and ocular symptoms concerning for cavernous sinus thrombosis. Treatment entails early administration of broad-spectrum intravenous antibiotics, anticoagulation, and surgical drainage when applicable. Accepted for publication July 31, 2018.

Pituitary Adenoma Apoplexy of the Orbit, Diagnosis, and Management With Presurgical Embolization
Orbital invasion of pituitary adenomas has been previously reported. In this report, the authors describe a 71-year-old female with a prolactinoma that presented with invasion of and apoplexy within the orbit. The patient underwent exenteration, followed by rapid tumor recurrence and growth. Given the hemorrhagic nature of the tumor, she subsequently underwent preoperative embolization and surgical resection. This case is notable in that it illustrates both apoplexy of a pituitary tumor within the orbit and the benefit of presurgical embolization. Accepted for publication August 15, 2018.

Orbitocerebral Mucormycosis in a Patient With Central Nervous System Lymphoma
A 61-year-old man with well-controlled diabetes mellitus type 2, cirrhosis from hepatitis C, alcohol abuse, and portal hypertension presented with painful vision loss and left orbital swelling. Imaging showed diffuse orbital, perineural, and pachymeningeal inflammation. He was initially diagnosed with neurosarcoidosis. However, cerebrospinal fluid analysis revealed central nervous system lymphoma, and lacrimal gland biopsy showed fungal organisms consistent with mucormycosis. The authors describe a case of Mucorales infection lacking sinonasal involvement and discuss the differential diagnosis and management of patients presenting with orbital and central nervous system inflammation from this uncommon fungal infection.

Nontraumatic Orbital Hemorrhage During Uncomplicated Labor
Septate Dermoid Cyst Mimicking Septate Lacrimal Sac Diverticulum
A Case of Hyaluronic Acid Induced Blindness With Ophthalmoplegia and Ptosis
Hyaluronic acid injection can lead to skin necrosis, visual loss, and other complications. The blindness with ophthalmoplegia and ptosis is a rare, but terrible and devastating complication. The disfigured appearance usually has significant impact on patient's social life. There is no standard treatment. A patient with hyaluronic acid induced blindness, ophthalmoplegia, and ptosis is reported. Six days after the onset, peribulbar/retrobulbar injections of high dosage hyaluronidase were performed. The orbital edema and ptosis immediately improved. The ophthalmoplegia and ptosis improved significantly within a month and resolved completely within 3 months, although the right vision remained blind. Peribulbar/retrobulbar injection of hyaluronidase is a potential rescue therapy for the hyaluronic acid induced ophthalmoplegia and ptosis. Accepted for publication August 9, 2018.

Study on the Aging Dynamics of the Periorbital Region: From Observation to Knowledge of Physiopathology
Purpose: Several anatomical and physio-pathologic studies of eyelid region have allowed the creation of theories on facial tissues aging dynamics, which have not been clarified yet. We assessed the signs of aging in the region over the time by observing the characteristics in the same person at different times of his/her life. Methods: We compared the position of the main anatomical landmarks of the eyelid region of 80 patients by overlaying their photographs when they were 20, 40, and 60 years old. Then we made comparisons in the group of men (40 people) and in the group of women (40 people) and between men and women. Results: The medial portion of the eyebrow was higher in the photograph taken at 60 years of age than in the one taken at 20 years old in 56.2% of cases; it was higher in 47.5% of cases when comparing the images at 20 and 40. The lateral portion of the eyebrow was seen higher in women in the 20 to 40 group, and it was seen lower in men at 60 years in statistical significance. In more than half of the patients observed, there was not a real descent of the eyebrow and the presence of a more or less accentuated form of upper eyelid's ptosis in the photograph at 60 (globally 47.5%, 55.0% of women and 40.0% of men). This condition was observed in 27.5% of the photographs at 40. There were changes in the horizontal dimension of the palpebral fissure (shortening in 53.7%, preserved in 33.7%, and increased in 12.5% of cases at 60 years old). The position of lateral canthus appeared lower in 40.0% of patients photographed at 60, but it was stable in those photographed at 40. The herniation of the upper eyelid bags was observed in 31.2% of the patients photographed at 60 years old but only in 13.7% at 40. Dermatochalasis of the upper eyelid was present in 67.5% of the people at 60 years old and in 55.0% of those seen when they were 40. Comparing men and women groups 20 to 40, dermatochalasis is more present in men than women at 40 years old with statistical significance. The eyelid-cheek junction was seen to be lower in 75.0% of cases at 60 and in 48.7% of cases at 40, and it is more represented in men than in women. Conclusion: We have highlighted some interesting elements, partly agreeing with the data already recorded by other authors', and our data suggest an important role of the eyelid structures senescence and its impact on the surrounding structures.

Pituitary Adenoma Apoplexy of the Orbit, Diagnosis, and Management With Presurgical Embolization
Orbital invasion of pituitary adenomas has been previously reported. In this report, the authors describe a 71-year-old female with a prolactinoma that presented with invasion of and apoplexy within the orbit. The patient underwent exenteration, followed by rapid tumor recurrence and growth. Given the hemorrhagic nature of the tumor, she subsequently underwent preoperative embolization and surgical resection. This case is notable in that it illustrates both apoplexy of a pituitary tumor within the orbit and the benefit of presurgical embolization. Accepted for publication August 15, 2018. The authors have no financial or conflicts of interest to disclose. Presented at Spring ASOPRS 2018, May 31 to June 2, 2018, Austin, TX. Address correspondence and reprint requests to Timothy J.

Study on the Aging Dynamics of the Periorbital Region: From Observation to Knowledge of Physiopathology
Purpose: Several anatomical and physio-pathologic studies of eyelid region have allowed the creation of theories on facial tissues aging dynamics, which have not been clarified yet. We assessed the signs of aging in the region over the time by observing the characteristics in the same person at different times of his/her life. Methods: We compared the position of the main anatomical landmarks of the eyelid region of 80 patients by overlaying their photographs when they were 20, 40, and 60 years old. Then we made comparisons in the group of men (40 people) and in the group of women (40 people) and between men and women. Results: The medial portion of the eyebrow was higher in the photograph taken at 60 years of age than in the one taken at 20 years old in 56.2% of cases; it was higher in 47.5% of cases when comparing the images at 20 and 40. The lateral portion of the eyebrow was seen higher in women in the 20 to 40 group, and it was seen lower in men at 60 years in statistical significance. In more than half of the patients observed, there was not a real descent of the eyebrow and the presence of a more or less accentuated form of upper eyelid's ptosis in the photograph at 60 (globally 47.5%, 55.0% of women and 40.0% of men). This condition was observed in 27.5% of the photographs at 40. There were changes in the horizontal dimension of the palpebral fissure (shortening in 53.7%, preserved in 33.7%, and increased in 12.5% of cases at 60 years old). The position of lateral canthus appeared lower in 40.0% of patients photographed at 60, but it was stable in those photographed at 40. The herniation of the upper eyelid bags was observed in 31.2% of the patients photographed at 60 years old but only in 13.7% at 40. Dermatochalasis of the upper eyelid was present in 67.5% of the people at 60 years old and in 55.0% of those seen when they were 40. Comparing men and women groups 20 to 40, dermatochalasis is more present in men than women at 40 years old with statistical significance. The eyelid-cheek junction was seen to be lower in 75.0% of cases at 60 and in 48.7% of cases at 40, and it is more represented in men than in women.

A Case of Hyaluronic Acid Induced Blindness With Ophthalmoplegia and Ptosis
Hyaluronic acid injection can lead to skin necrosis, visual loss, and other complications. The blindness with ophthalmoplegia and ptosis is a rare, but terrible and devastating complication. The disfigured appearance usually has significant impact on patient's social life. There is no standard treatment. A patient with hyaluronic acid induced blindness, ophthalmoplegia, and ptosis is reported. Six days after the onset, peribulbar/retrobulbar injections of high dosage hyaluronidase were performed. The orbital edema and ptosis immediately improved. The ophthalmoplegia and ptosis improved significantly within a month and resolved completely within 3 months, although the right vision remained blind. Peribulbar/retrobulbar injection of hyaluronidase is a potential rescue therapy for the hyaluronic acid induced ophthalmoplegia and ptosis. Accepted for publication August 9, 2018.

Aberrant gastroduodenal artery with splenic origin
Abstract
Purpose
Knowledge of the wide variability in celiac trunk branches is of paramount importance when planning an abdominal surgery.
Methods
We, hereby, report a previously undescribed origin of the gastroduodenal artery discovered on an abdominal angio-CT.
Results
CT-angiogram performed on a 33-year-old female randomly revealed a new variant of gastroduodenal artery arising directly from the splenic artery along with other vascular aberrations. The latter were previously described in medical literature.
Conclusion
High-quality preoperative imaging is crucial for identification of visceral artery variations, as those can technically modify the surgical or interventional procedure.

Outcomes of Surgical Repair of Skull Base Defects Following Endonasal Pituitary Surgery: A Retrospective Observational Study
Abstract
Skull base defects following endonasal surgery for pituitary macroadenoma need to be addressed during the surgery to prevent serious postoperative complications like cerebrospinal fluid (CSF) leak. The objective of this study is to assess the incidence of CSF leak following pituitary surgery and the methods of effective skull base repair. This is a retrospective observational study conducted in a tertiary care hospital after obtaining due clearance from the Institutional ethics committee. The charts of patients who underwent endonasal pituitary surgery between 2013 and 2018 were studied and details noted. Patients undergoing revision surgery or with history of preoperative radiotherapy were excluded from the study. 52 patients were included in the study. Based on the type of CSF leak, the patients were grouped into four. 19 patients (36.5%) had an intraoperative CSF leak. 3 patients developed a postoperative CSF leak. Based on the histopathology, 4 patients had ACTH secreting tumor. 8 patients had growth hormone secreting tumor, 22 had gonadotropin secreting tumor, 9 patients had a non-functioning tumour and 9 patients had prolactinoma. The type of skull base repair performed in these patients were grouped into 4.18 patients underwent type I repair, 21 patients underwent type II repair, 8 patients underwent type III repair and 5 patients underwent type IV repair. We have observed that the pedicled nasoseptal flap is particularly advantageous over other repair techniques, especially in low pressure leaks. The strategy for skull base repair should be tailored to suit each patient to minimise the occurrence of morbidity and the duration of hospital stay.

The Use of Dynamic Contrast-Enhanced Perfusion MRI in Differentiating Benign and Malignant Thyroid Nodules
Abstract
To investigate the efficacy of perfusion magnetic resonance imaging (MRI) in benign-malignant differentiation of thyroid nodules. Images from 24 patients with thyroid masses were obtained using dynamic contrast enhanced MRI (DCE-MRI) at 3-T MR. DCE-MRI images were evaluated by post-processing of selected regions of interest (ROIs) on software, thus eliciting quantitative data for each voxel within the ROI. Ktrans, Ve, Kep, iAUC and chi2 were calculated automatically. The DCE-MRI values of benign and malignant lesions were then compared. Mean Ktrans and iAUC values in malignant lesions were significantly lower than those in benign lesions (p = 0.028 and 0.049). Ktrans, Kep, and iAUC values in malignant lesions were statistically significantly lower than normal parenchyma values. In contrast to other tissues, the perfusion MRI findings of thyroid masses exhibit a decrease in Ktrans and iAUC values as malignancy increases. Perfusion MRI may be useful in differentiating benign and malignant thyroid nodules once a cut-off value has been determined by other studies.

Eosinophilia and reduced STAT3 signalling affect neutrophil cell death in autosomal-dominant Hyper-IgE syndrome.
This study was undertaken to functionally characterize neutrophils in STAT3-deficient HIES patients and to analyse whether the patients` eosinophilia affects the neutrophil phenotype in S. aureus infection. Neutrophil functions and cell death kinetics were studied in eight STAT3-deficient patients. Moreover, the response of STAT3-deficient neutrophils to S. aureus and the impact of autologous eosinophils on pathogen-induced cell death were analysed. No specific aberrations in neutrophil functions were detected within this cohort. However, the half-life of STAT3-deficient neutrophils ex vivo was reduced, which was partially attributable to the presence of eosinophils. Increased S. aureus-induced cell lysis, dependent on the staphylococcal virulence controlling agr-locus, was observed in STA...

A non-interventional multicenter study to document the implants success and survival rates in daily dental practices of the CONELOG screw-line implant
Abstract
Objective
This multicenter prospective non-interventional study evaluated the success and survival of the CONELOG implants inserted according to the standard protocol with one- or two-step surgery in daily practice three years after loading. Changes of soft tissue and bone level over time, esthetical outcome, and patient satisfaction were assessed.
Materials and methods
The study included patients in six centers. The implants were used in accordance with standard practice of each particular center, and the use was documented systematically. Failure rate, implant success, bone level changes, different clinical parameters, and patients' satisfaction were assessed.
Results
In total, 130 dental implants were placed in 94 patients (64 female, 30 male). Mean age of patients was 50.4 ± 13.7. At 3-year post-loading, 108 implants in 78 patients were available for evaluation. Success and survival rate were 98.4% after placement and 100% 36 months post-loading. Bone loss from surgery to loading was 0.52 ± 0.55 mm. From loading to 36 months post-loading, the bone level change remained stable. Patient assessments were performed for function, ability to chew, speech, esthetics, and general satisfaction. Patients were very satisfied (82.3%) or satisfied (16.1%). None of the patients was dissatisfied.
Conclusion
The 3-year results of this non-interventional multicenter study indicate that the CONELOG implants are reliable and effective over the course of the observation while used in standard conditions of daily environment and confirm the results obtained in controlled clinical trials.
Clinical relevance
Performance of CONELOG implants under daily routine is similar to controlled clinical trials.

Author(s): Gert Reiter, Clemens Reiter, Corina Kräuter, Michael Fuchsjäger, Ursula Reiter
Abstract
While an enormous number of studies have documented pathological alterations of the myocardial native longitudinal relaxation time (T1) and the fraction of the extracellular myocardial volume (ECV), it has also become clear that continuously evolving T1 mapping sequence, acquisition and evaluation techniques have a substantial impact on quantitative results, making the translation of reported findings into routine clinical use particularly challenging. To provide a basis for the discussion of pathological myocardial T1 and ECV alterations, the present review aims to summarize the methodological aspects of myocardial T1 mapping along with technical and physiological factors influencing results and normal ranges of myocardial native T1 and ECV reported across studies.

Use of Non-Invasive Measures to Predict Cochlear Synapse Counts
Publication date: Available online 13 October 2018
Source: Hearing Research
Author(s): Naomi F. Bramhall, Garnett P. McMillan, Sharon G. Kujawa, Dawn Konrad-Martin
Abstract
Cochlear synaptopathy, the loss of synaptic connections between inner hair cells and auditory nerve fibers, has been documented in animal models of aging, noise, and ototoxic drug exposure, three common causes of acquired sensorineural hearing loss in humans. In each of these models, synaptopathy begins prior to changes in threshold sensitivity or loss of hair cells; thus, this underlying injury can be hidden behind a normal threshold audiogram. Since cochlear synaptic loss cannot be directly confirmed in living humans, non-invasive assays will be required for diagnosis. In animals with normal auditory thresholds, the amplitude of wave 1 of the auditory brainstem response (ABR) is highly correlated with synapse counts. However, synaptopathy can also co-occur with threshold elevation, complicating the use of the ABR alone as a diagnostic measure. Using an age-graded series of mice and a partial least squares regression approach to model structure-function relationships, this study shows that the combination of a small number of ABR and distortion product otoacoustic emission (DPOAE) measurements can predict synaptic ribbon counts at various cochlear frequencies to within 1-2 synapses per inner hair cell of their true value. In contrast, the model, trained using the age-graded series of mice, overpredicted synapse counts in a small sample of young noise-exposed mice, perhaps due to differences in the underlying pattern of damage between aging and noise-exposed mice. These results provide partial validation of a noninvasive approach to identify synaptic/neuronal loss in humans using ABRs and DPOAEs.
