NSAID (nonsteroidal anti-inflammatory drugs) Induced Stevens Johnson Syndrome in a 50-year-old woman: A case study

Stevens-Johnson Syndrome (SJS) is a severe and rare adverse drug reaction associated with significant morbidity and mortality. Although SJS is commonly triggered by multiple drugs, non-steroidal anti-inflammatory drugs (NSAIDs), including diclofenac, have been frequently implicated. A middle-aged woman, who is 50 years old, has a prior medical record of high blood pressure, type 2 diabetes, and has recently suffered from a pulmonary embolism. She was later admitted to the intensive care unit (ICU), where she was ultimately diagnosed with Steven Johnson syndrome. Careful drug selection, close monitoring of patients with predisposing factors, and prompt identification of adverse events are crucial to prevent severe drug reactions.

The devastating impact of unresectable infectious undifferentiated pleomorphic sarcoma in the gluteal region: A case report

INTRODUCTION AND IMPORTANCE

Undifferentiated pleomorphic sarcoma (UPS), previously known as malignant fibrous histiocytoma (MFH), is a highly aggressive soft tissue sarcoma characterized by its pleomorphic histology and lack of differentiation.

CASE PRESENTATION

A 35-year-old man visited our oncology department with a complaint of a growing mass in his left buttock area. The mass had been increasing in size for the past six months, affected by local and systemic infection. While it was initially painless, the patient started feeling discomfort during sitting and physical activities a few weeks, but later the complication of tumor became more aggressive.

CLINICAL DISCUSSION

UPS can arise in various anatomical sites, including the extremities, trunk, retroperitoneum, and head and neck region. Clinically, UPS may present as a rapidly growing mass, often with pain and limited range of motion. However, the presentation may vary depending on the site of origin. Treatment for UPS typically involves surgical resection, aiming to remove the tumor completely. Depending on the size, location, and aggressiveness of the tumor, additional treatments such as radiation therapy or chemotherapy may be recommended.

CONCLUSION

Undifferentiated pleomorphic sarcoma (UPS) represents a rare and aggressive soft tissue sarcoma requiring prompt and accurate diagnosis for appropriate management. With its non-specific clinical presentation and histological features, UPS can be challenging to differentiate from other soft tissue tumors.

"Are They Listening, and Do They Find It Useful?"-Evaluation of Mid-Rotation Formative Subjective and Objective Feedback to Radiology Trainees

BACKGROUND

Residents commonly receive only end-of-rotation evaluations and thus are often unaware of their progress during a rotation. In 2021, our neuroradiology section instituted mid-rotation feedback in which rotating residents received formative subjective and objective feedback. The purpose of this study was to describe our feedback method and to evaluate if residents found it helpful.

METHODS

Radiology residents rotate 3-4 times on the neuroradiology service for 1-month blocks. At the midpoint of the rotation (2 weeks), 7-10 neuroradiology attendings discussed the rotating residents' subjective performance. One attending was tasked with facilitating this discussion and taking notes. Objective metrics were obtained from our dictation software. Compiled feedback was relayed to residents via email. A 16-question anonymous survey was sent to 39 radiology residents (R1-R4) to evaluate the perceived value of mid-rotation feedback. Odds ratios and 95% confidence intervals were computed using logistic regression.

RESULTS

Sixty-nine percent (27/39) of residents responded to the survey; 92.6% (25/27) of residents reported receiving mid-rotation feedback in ≥50% of neuroradiology rotations; 92.3% (24/26) of residents found the subjective feedback helpful; 88.4% (23/26) of residents reported modifying their performance as suggested (100% R1-R2 vs 70% R3-R4; OR: 15.4 CI:1.26, >30.0);59.1% (13/22) of residents found the objective metrics helpful (75% R1-R2 vs 40% R3-R4; OR: 3.92 CI:0.74, 24.39) and 68.2% (15/22) stated they modified their performance based on these metrics (83.3% R1-R2 vs 50.0% R3-R4; OR:4.2 CI:0.73, 30.55); and 84.6% (22/26) of residents stated that mid-rotation subjective feedback and 45.5% (10/22) stated that mid-rotation objective feedback should be implemented in other sections.

CONCLUSIONS

Majority of residents found mid-rotation feedback to be helpful in informing them about their progress and areas for improvement in the neuroradiology rotation, more so for subjective feedback than objective feedback. The majority of residents stated all rotations should provide mid-rotation subjective feedback.

Effect of spiritual care on the quality of life in patients who underwent intracranial hemorrhage surgery: a randomized controlled trial

INTRODUCTION

One of the most important complications of stroke after intracranial haemorrhage surgery is impaired quality of life. This study was conducted to determine the impact of spiritual care on the quality of life of stroke patients.

METHODS

This single-blind clinical trial with a pre-test and post-test design was conducted on 100 stroke patients. Participants were recruited and randomly assigned to a control group and an intervention group. The stroke-specific quality of life (SS -QoL) scale was used to assess the quality of life of stroke patients. The intervention group received four sessions of spiritual care.

RESULTS

The independent t -test showed no significant difference between the two groups in the mean quality of life score ( t =-0.120, P =0.281) and its dimensions before the intervention. However, after the intervention, the results showed a significant difference between the two groups in terms of the mean quality of life score ( t =1.984, P <0.001) and its dimensions. In addition, the results of the paired t -test showed that in the intervention group, the mean score of quality of life ( t =5.161, P <0.001) and its dimensions were significantly different before and after the intervention. Furthermore, the results showed that before and after the intervention in the control group, the mean score of quality of life ( t =1.109, P =0.614) and its dimensions were not significantly different.

CONCLUSIONS

Based on this results, the authors strongly recommend the use of spiritual care as a holistic care and complementary method to improve the symptoms and quality of life of stroke patients.

The effects of coadministration of curcumin and vitamin E on the reproductive system of diabetic male rats; An experimental study

Introduction

Diabetes causes testicular damage due to oxidative stress. Nowadays, the use of vitamins and antioxidants is one of the common methods to treat this disease. Therefore, the aim of this study is to investigate the effect of single and combined administration of these two substances on the reproductive system of male diabetic rats.

Method and materials

In this study, 48 adult male Wistar rats weighing 250-270 grammes were divided into 6 groups: Control group, diabetic group, vehicle group, vitamin E, curcumin group, and vitamin E and curcumin group. The control group was the healthy group, and in the other groups, the rats were made diabetic by streptozotocin (60 mg/kg/ip). The vehicle group received 1 ml of olive oil, the vitamin E group (100 mg/kg/ip) received Vit.E, and the curcumin group (50 mg/kg/ip) received Cu. The group of rats received vitamin E and curcumin. At the end of the sixth week after treatment, blood was taken from the rats and biochemical analysis was performed to check the amount of malondialdehyde (MDA), LH hormones and serum testosterone, then the rats were killed and their testes and epididymides were removed. The weight of the testes and sperm parameters, the maturity of sperm nuclei and the integrity of their DNA were checked. The number of spermatogenic cells was determined by histological examination.

Results

This study showed that diabetes caused a decrease in testicular weight, sperm count, motility, and viability, an increased percentage of sperm with immature nuclei, and an increased percentage of sperm with denatured DNA. In addition, diabetes decreased the average number of matogenic sperm, and biochemical results showed that diabetes increased the level of MDA and decreased the level of the hormones LH and testosterone. Treatment with vitamin E, curcumin and their combination improved all these parameters, and this improvement was significant in the Toam group.

Conclusion

Combined administration of vitamin E and curcumin in diabetic rats significantly improves sperm parameters, matogenic sperm count, and improves MDA levels, LH, and serum testosterone compared with separate treatment.

Assessing the Potential of a Deep Learning Tool to Improve Fracture Detection by Radiologists and Emergency Physicians on Extremity Radiographs

RATIONALE AND OBJECTIVES

To evaluate the standalone performance of a deep learning (DL) based fracture detection tool on extremity radiographs and assess the performance of radiologists and emergency physicians in identifying fractures of the extremities with and without the DL aid.

MATERIALS AND METHODS

The DL tool was previously developed using 132,000 appendicular skeletal radiographs divided into 87% training, 11% validation, and 2% test sets. Stand-alone performance was evaluated on 2626 de-identified radiographs from a single institution in Ohio, including at least 140 exams per body region. Consensus from three US board-certified musculoskeletal (MSK) radiologists served as ground truth. A multi-reader retrospective study was performed in which 24 readers (eight each of emergency physicians, non-MSK radiologists, and MSK radiologists) identified fractures in 186 cases during two independent sessions with and without DL aid, separated by a one-month washout period. The accuracy (area under the receiver operating curve), sensitivity, specificity, and reading time were compared with and without model aid.

RESULTS

The model achieved a stand-alone accuracy of 0.986, sensitivity of 0.987, and specificity of 0.885, and high accuracy (> 0.95) across stratification for body part, age, gender, radiographic views, and scanner type. With DL aid, reader accuracy increased by 0.047 (95% CI: 0.034, 0.061; p = 0.004) and sensitivity significantly improved from 0.865 (95% CI: 0.848, 0.881) to 0.955 (95% CI: 0.944, 0.964). Average reading time was shortened by 7.1 s (27%) per exam. When stratified by physician type, this improvement was greater for emergency physicians and non-MSK radiologists.

CONCLUSION

The DL tool demonstrated high stand-alone accuracy, aided physician diagnostic accuracy, and decreased interpretation time.

Self-esteem and optimism in patients with major depression disorder: a cross-sectional study

Background

Depressive disorders are common mental illnesses characterized by persistent feelings of sadness, hopelessness, and loss of interest in activities. Self-esteem refers to the appraisal of one's worth and personality, whereas optimism reflects a positive attitude and the expectation of positive outcomes. Therefore, the present study aims to determine the average self-esteem and optimism of patients with depression in 2022.

Methods

The present study is a single center and prospective descriptive-analytical study in which 121 patients out of 154 participants with major depression using convenience sampling were studied. Recruitment started on 10 June 2022 and ended on 12 July 2022. Data were collected using a demographic questionnaire, the Rosenberg Self-Esteem Scale (RSES), and the Revised Life Orientation Test (LOT -R). Data analysis was performed using statistical tests and the Pearson correlation coefficient with SPSS software version 21.

Results

The mean and SD of patients' self-esteem scores were 14.68±1.30, and the mean and SD for optimism scores were 9.90±1.68. Pearson correlation analysis showed that educational level had a significant inverse relationship with patients' self-esteem scores (r=-0.009, P=0.03), and sex had a significant relationship with patients' optimism scores (r=0.175, P=0.008).

Conclusion

Considering the importance of self-esteem and optimism in the recovery and return to society of patients with major depression, it is necessary to take measures to strengthen and increase self-esteem and optimism in these patients.

Decreasing Workflow and Educational Interruptions in the Reading Room: Working Smarter, Not Harder

OBJECTIVE

Disruptions in image interpretation lead to interrupted education and inefficiency, and ultimately delay patient care. In the academic reading room, time can often be spent rerouting phone calls. The objective of this study was to evaluate resident perception of current workflow, decrease interruptions, and improve patient care and resident education by implementing a cost-effective automated centralized phone tree.

MATERIALS AND METHODS

Phone call records were obtained between January 25 and February 23, 2021 and May 3 and June 30, 2021 prior to implementation of an automated centralized phone tree within the Emergency Radiology reading room. Calls during weekday business hours were evaluated. Postimplementation phone records were obtained over 4 weeks (August 20-September 16, 2021). Residents on rotation were surveyed prior to and after phone tree implementation regarding the qualitative impact.

RESULTS

The total number of phone calls decreased after phone tree implementation to 8 calls over a 19-day period from 100-200 phone calls over a 20-22 day period. There is a statistically significant difference (p-value < 0.017) in the median number of phone calls postimplementation for all compared preimplementation time points. Resident surveys also demonstrate a statistically significant improvement (p-value < 0.05) in the evaluated metrics.

CONCLUSIONS

Data demonstrate a quantitative decrease in the number of calls arriving at the Emergency Radiology reading room as well as qualitative improvements in resident workplace satisfaction, feelings of burnout, and burden of interruptions. These data suggest that a self-directed triage system (eg, phone tree) could provide a cost-effective and simple means of decreasing interruptions.

Anki Flashcards for Radiology Education

From online textbooks to educational social media posts, digital learning tools are transforming medical education. Spaced repetition programs are a popular tool, with 70% of first-year medical students reporting using the free, open-source flashcard application Anki.1 The Anki program pairs active recall and spaced repetition learning principles with a simple but versatile user interface.2 Spaced repetition flashcard programs such as Anki are uniquely suited to radiology education because they strengthen image-based recall, a necessary skill for radiology trainees to develop. In this review, we will describe the science behind active recall and spaced repetition programs, introduce the Anki platform, and describe future directions for its potential as an educational resource for radiology.

Play in the reading room: Utilizing soft modeling compound to teach musculoskeletal anatomy and pathology

PROBLEM DESCRIPTION

Musculoskeletal (MSK) anatomy and pathology from a radiology perspective can be difficult to conceptualize and understand due to the challenge of visualizing 3D structures in stacks of 2D imaging. Consequently, trainees may benefit from inexpensive methods that can help trainees better visualize MSK anatomy and pathology. The purpose of this study is to provide proof of concept for inexpensive methodology to help learners such as radiology residents quickly and inexpensively understand musculoskeletal anatomy and pathology. This can help trainees become better at applying musculoskeletal knowledge to clinical practice.

INSTITUTIONAL METHODOLOGY

Soft-modeling compounds such as Play-Doh® was utilized in a variety of colors with pottery tools to recreate 3D models of challenging MSK anatomy and pathology for trainees. Qualitative feedback from the residents was collected.

RESULTS

Eighteen different pathological conditions across six major bone structures were modeled with a soft modeling compound. Residents qualitatively identified the experience as educational in terms of helping them better understand MSK pathology and positive in terms of making learning fun, less stressful, and memorable due to uniqueness of the learning modality. Residents report challenges modeling complex anatomical features and pathology via this methodology.

CONCLUSION

Radiology residents and other learners can enhance their knowledge of musculoskeletal anatomy and pathology via utilization of inexpensive soft modeling compounds. This may offer a cheaper and more time sensitive alternative to current 3-dimensional hardware and software technologies being developed for educational purposes. Additional work needs to be done to examine the utility of this methodology across larger and diverse groups of learners.

Maggot therapy, alginate dressing, and surgical sharp debridement: Unique path to save unresponsive diabetic foot ulcer

INTRODUCTION AND IMPORTANCE

Diabetic foot ulcers are a severe complication of diabetes mellitus, affecting a significant proportion of the diabetic population. In some cases, ulcer progression and infection can lead to the need for amputation.

CASE PRESENTATION

An 84-year-old male with a history of poorly controlled type 2 DM and HTN presented with an infected DFU on the plantar aspect of his right foot. This case report illustrates the successful management of an 84-year-old patient with a DFU amputation candidate, emphasizing the effectiveness of a combined treatment approach.

CLINICAL DISCUSSION

Conventional treatment options, including antibiotic therapy, often fail to provide adequate healing in these high-risk patients. Alternative approaches, such as maggot therapy, which involves the application of sterile maggots to the wound bed, have shown promising results.

CONCLUSION

This case highlights the potential therapeutic benefits and clinical efficacy of such a combined treatment approach, particularly in challenging cases with limited response to conventional therapies. Further studies and randomized trials may be warranted to support the incorporation of this therapy combination into clinical practice guidelines for DFU management.

What Is the Prevalence of Clinically Important Findings Among Incidentally Found Osseous Lesions?

BACKGROUND

Patients with incidentally found musculoskeletal lesions are regularly referred to orthopaedic oncology. Most orthopaedic oncologists understand that many incidental findings are nonaggressive and can be managed nonoperatively. However, the prevalence of clinically important lesions (defined as those indicated for biopsy or treatment, and those found to be malignant) remains unknown. Missing clinically important lesions can result in harm to patients, but needless surveillance may exacerbate patient anxiety about their diagnosis and accrue low-value costs to the payor.

QUESTIONS/PURPOSES

(1) What percentage of patients with incidentally discovered osseous lesions referred to orthopaedic oncology had lesions that were clinically important, defined as those receiving biopsy or treatment or those found to be malignant? (2) Using standardized Medicare reimbursements as a surrogate for payor expense, what is the value of reimbursements accruing to the hospital system for the imaging of incidentally found osseous lesions performed during the initial workup period and during the surveillance period, if indicated?

METHODS

This was a retrospective study of patients referred to orthopaedic oncology for incidentally found osseous lesions at two large academic hospital systems. Medical records were queried for the word "incidental," and matches were confirmed by manual review. Patients evaluated at Indiana University Health between January 1, 2014, and December 31, 2020, and those evaluated at University Hospitals between January 1, 2017, and December 31, 2020, were included. All patients were evaluated and treated by the two senior authors of this study and no others were included. Our search identified 625 patients. Sixteen percent (97 of 625) of patients were excluded because their lesions were not incidentally found, and 12% (78 of 625) were excluded because the incidental findings were not bone lesions. Another 4% (24 of 625) were excluded because they had received workup or treatment by an outside orthopaedic oncologist, and 2% (10 of 625) were excluded for missing information. A total of 416 patients were available for preliminary analysis. Among these patients, 33% (136 of 416) were indicated for surveillance. The primary indication for surveillance included lesions with a benign appearance on imaging and low clinical suspicion of malignancy or fracture. A total of 33% (45 of 136) of these patients had less than 12 months of follow-up and were excluded from further analysis. No minimum follow-up criteria were applied to patients not indicated for surveillance because this would artificially inflate our estimated rate of clinically important findings. A total of 371 patients were included in the final study group. Notes from all clinical encounters with orthopaedic and nonorthopaedic providers were screened for our endpoints (biopsy, treatment, or malignancy). Indications for biopsy included lesions with aggressive features, lesions with nonspecific imaging characteristics and a clinical picture concerning for malignancy, and lesion changes seen on imaging during the surveillance period. Indications for treatment included lesions with increased risk of fracture or deformity, certain malignancies, and pathologic fracture. Diagnoses were determined using biopsy results if available or the documented opinion of the consulting orthopaedic oncologist. Imaging reimbursements were obtained from the Medicare Physician Fee Schedule for 2022. Because imaging charges vary across institutions and reimbursements vary across payors, this method was chosen to enhance the comparability of our findings across multiple health systems and studies.

RESULTS

Seven percent (26 of 371) of incidental findings were determined to be clinically important, as previously defined. Five percent (20 of 371) of lesions underwent tissue biopsy, and 2% (eight of 371) received surgical intervention. Fewer than 2% (six of 371) of lesions were malignant. Serial imaging changed the treatment of 1% (two of 136) of the patients, corresponding to a rate of one in 47 person-years. Median reimbursements to work up the incidental findings analyzed was USD 219 (interquartile range USD 0 to 404), with a range of USD 0 to 890. Among patients indicated for surveillance, the median annual reimbursement was USD 78 (IQR USD 0 to 389), with a range of USD 0 to 2706.

CONCLUSION

The prevalence of clinically important findings among patients referred to orthopaedic oncology for incidentally found osseous lesions is modest. The likelihood of surveillance resulting in a change of management was low, but the median reimbursements associated with following these lesions was also low. We conclude that after appropriate risk stratification by orthopaedic oncology, incidental lesions are rarely clinically important, and judicious follow-up with serial imaging can be performed without incurring high costs.

Pyknodysostosis: A case report of an 8-year-old male with a rare genetic disorder

INTRODUCTION AND IMPORTANCE

Pyknodysostosis is a rare genetic disorder characterized by skeletal and craniofacial abnormalities. It is an autosomal recessive disorder caused by mutations in the gene encoding cathepsin K. Pyknodysostosis is associated with short stature, brittle bones, and distinctive facial features.

CASE PRESENTATION

This case report presents the clinical manifestations, diagnostic challenges, and management strategies of an 8-year-old male with pyknodysostosis, an extremely rare genetic disorder characterized by skeletal and craniofacial abnormalities. The patient's clinical presentation, radiographic findings, genetic testing results, and treatment approach are discussed. Additionally, the importance of genetic counseling and multidisciplinary care in managing this condition is emphasized.

CLINICAL DISCUSSION

A multidisciplinary approach involving orthopedics, genetics, dentistry, and psychological support is crucial for managing patients with pyknodysostosis. Regular follow-up visits, careful monitoring of fractures, and appropriate interventions can improve the patient's quality of life and reduce complications.

CONCLUSION

The importance of early recognition, genetic testing, and multidisciplinary care is emphasized for effective treatment and support. Further research is needed to enhance our understanding of this rare genetic disorder and develop targeted therapies.

Asymptomatic Bone Marrow Edema in Weight-bearing Bones in Athletes and Military Trainees: A Systematic Literature Review

Asymptomatic bone marrow edema (aBME) is a non-specific radiographic finding often found in athletes. Although aBME may represent the body's physiological response to training load, the etiology, MRI characteristics, and natural history of aBME remain unknown. To better characterize aBME in the lower extremities of military trainees and athletes. A systematic literature review in accordance with PRISMA guidelines was performed to identify primary research articles reporting on aBME in the lower extremities of athletes and military trainees. We identified 347 unique articles and after applying inclusion and exclusion criteria, 10 articles were included for qualitative synthesis. There were a total of 444 patients with an average age of 28.4±9.6 included. The most commonly used MRI sequences were proton-density with fat-saturation and T1-weighted imaging. The pattern of BME was inconsistently described, with various classification schemas used. The changes in aBME during longitudinal follow-up were dynamic and demonstrated both radiographic progression and regression. aBME is a highly prevalent and radiographically dynamic entity observed in high-level athletes and military trainees. Although follow-up was limited in the included studies, aBME may represent a natural, non-pathologic, reaction in response to specific biomechanical stressors.

Surgical management on a rare type of vertical liner fracture of tibia: A case report study

INTRODUCTION AND IMPORTANCE

The vertical liner fracture of the tibia is an infrequent and intricate injury that presents considerable difficulties in terms of its diagnosis, treatment, and long-term consequences. This particular fracture pattern is distinguished by a vertical line of fracture along the length of the tibial shaft, spanning from the proximal to the distal end.

CASE PRESENTATION

The 31-year-old female patient, who had no prior medical conditions, presented to the emergency department with complaints of intense pain and impaired ambulation in her right lower limb. She reported an accidental fall while descending a staircase, resulting in substantial impact and pressure on her right leg.

CLINICAL DISCUSSION

While fractures of the tibia are frequently encountered, there exist exceptional instances of vertical liner fractures within this category. A vertical long liner fracture of the tibia denotes a distinct fracture type in the elongated bone of the lower limb, characterized by a vertical fracture line that extends along the length of the bone.

CONCLUSION

Vertical liner fractures of the tibia, although rare, are distinct from more common tibial fracture patterns. Accurate diagnosis and thorough evaluation using various imaging methods are crucial for assessing the extent of the fracture and any associated injuries.

Diabetic foot ulcer: Successful healing with combination therapy, including surgical debridement, maggot therapy, and negative pressure wound therapy

INTRODUCTION AND IMPORTANCE

Diabetic foot ulcers (DFUs) are a common and serious complication of diabetes. A variety of treatments available to help heal diabetic foot ulcers, including sharp debridement, maggot therapy, and negative pressure wound therapy.

CASE PRESENTATION

This case report presents the case study of a male patient with an 8-year history of diabetes who developed a diabetic foot ulcer. The patient was undergoing treatment with metformin and insulin. Despite the severity of the ulcer, a combination therapy approach, including surgical debridement, maggot therapy, and negative pressure wound therapy, was implemented, leading to successful healing.

CLINICAL DISCUSSION

DFUs are caused by various pathological mechanisms, the single therapy would lead to a very low level of recovery. Therefore, DFU management requires multimodal care and interdisciplinary treatment.

CONCLUSION

This case study highlights the effectiveness of a multimodal treatment strategy for diabetic foot ulcers, emphasizing the importance of individualized care and combining evidence-based practices.

Decoding Program Signals: A Radiology Residency Program's Experience With the ERAS Supplemental Application

The ERAS supplemental application has had a profound impact on the interview selection process. At our institution, we found the information in the supplemental application, particularly program signals, especially useful when inviting applicants for interviews. Applicant data was reviewed from this application cycle and the previous cycle and was subcategorized according to various demographic variables. Our analysis revealed that we were able to invite more geographically diverse candidates compared to last year. Program signaling was also beneficial for applicants in demonstrating interest in our program. 47% of interview offers were sent to those who had signaled, despite only 5% of total applications containing a program signal to our institution. Overall, we viewed the supplemental application favorably and reaffirmed its value in the interview selection process.

Scheduling Musculoskeletal MRI for Patients With Metallic Hardware: Initial Observations on Decreasing Nondiagnostic and Repeat Examinations at a Multisite Academic Medical Center

OBJECTIVE

As healthcare delivery systems expand to include multiple imaging centers, the process of scheduling patients at the site which best meets their needs continues to become more complex. This quality improvement study aims to create a protocol for patients with metallic hardware at sites with metallic artifact reduction sequences (MARS), increasing the proportion of exams that are diagnostic and reducing the need for repeat imaging.

MATERIALS AND METHODS

The study population included 322 patients with metallic hardware receiving an MRI at a large multisite healthcare system, divided into a pre-intervention and postintervention cohort. A retrospective PACS query was performed using several keywords in musculoskeletal MRI reports indicating the presence of metallic hardware. This cohort was studied to better understand the existing system failures. An intervention was then implemented by meeting with the departmental RIS and scheduling teams to discuss workflow when scheduling exams for patients with metallic hardware System changes were implemented and results were again studied retrospectively.

RESULTS

Before protocol implementation, 134/244 (55%) of exams were performed at sites with metallic artifact reduction sequences which improved to 54 of 78 (69%) in the postintervention cohort (P = 0.02). Additionally, the number of exams performed on 3T MRI machines pre-intervention was 14 of 244 (5.7%) compared to 1 of 78 (1.2%) postintervention (P = 0.13). The rate of nondiagnostic exams in the preintervention cohort was significantly higher at 41 of 244 (16.8%) when compared to the postintervention cohort at 4 of 78 (5.1% P = 0.01).

CONCLUSIONS

The implementation of this quality improvement protocol reduced the rate of nondiagnostic MSK MRI exams and reduced the inappropriate use of 3T scanners, ultimately saving time and cost for both patients and the health care system.

Deep excision surgery of face due to cruel invasion of basal cell carcinoma: A case report study

INTRODUCTION AND IMPORTANCE

The predominant variant of skin cancer is Basal cell carcinoma (BCC), constituting about 80 % of all non-melanoma skin cancers on a global scale. Typically, it manifests on skin surfaces that are frequently exposed to sunlight, such as the neck, face, and ears.

CASE PRESENTATION

A 65-year-old man presented to a specialized cancer hospital with a large pigmented lesion on the left cheek that had gradually increased in size for about a year. The tumor had become raised and ulcerated, which necessitated deep surgery on his face due to extensive invasion of BCC was done.

CLINICAL DISCUSSION

Basal cell carcinoma is a slow-growing, locally invasive cancerous tumor of the basal cells of the skin, which line the deepest layer of the epidermis. BCC often occurs on areas of the body that are exposed to the sun. It develops in response to cumulative UV irradiation and sporadic UV irradiation, as occurs with sunburns.

CONCLUSION

BCC is a common and potentially devastating skin cancer that primarily affects fair-skinned people over the age of 50. Lesions on the face can be particularly challenging. Early detection and treatment is critical to minimize the need for extensive excision and reconstruction.

Surgical excision for gigantic bilateral pulmonary hydatid cyst in a 14-year-old adolescent: A case report study

INTRODUCTION AND IMPORTANCE

Bilateral pulmonary hydatid cysts in adolescents are rare and present unique diagnostic and treatment challenges. Adolescents with pulmonary hydatid disease often present with nonspecific symptoms such as cough, abdominal pain, nausea, vomiting, and hepatosplenomegaly.

CASE PRESENTATION

This case is about 14-year-old adolescent who reported feeling a mass in his chest and experienced a loss of appetite. Imaging studies were performed which showed the presence of bilateral hydatid cyst in the lung. The cyst contents were sent for histopathological analysis, which confirmed the diagnosis of hydatid cysts.

CLINICAL DISCUSSION

The clinical presentation of hydatid cysts varies depending on the organs involved. Bilateral hydatid cysts may occur in various organs such as liver, lung, brain, spleen, kidney, bone and other sites. Diagnosis of bilateral hydatid cysts in adolescents is difficult because symptoms may be nonspecific and the cysts may not be apparent until they reach a sufficient size. The type of surgical approach depends on the location, size, and number of cysts.

CONCLUSION

Bilateral pulmonary hydatid cysts have become an increasingly important diagnosis in adolescent patients. Imaging plays a critical role in prompt diagnosis, and surgical intervention remains the mainstay of management. There are limited studies regarding the management of such rare cases, but through a multidisciplinary approach, improved outcomes can be achieved.

Ectopia cordis with multiple ventricular septal defect and sternal cleft in a newborn: a case report

Ectopia cordis is a rare type of malformation where the heart is not located normally. It may be partially or completely located outside the thoracic cavity and can be associated with other congenital abnormalities.

Case presentation

This case report is of a 34-week- and 6-day-old female fetus with a birth weight of 2040 g, a height of 41 cm, and a head circumference of 32 cm. The initial physical examination revealed a responsive newborn with an externalized heart outside the chest, with pericardium protection. In addition, a thoracic wall defect was detected suggesting incomplete formation of the septum bone. Moreover, in this case, the echocardiography report showed a multiple ventricular septal defect.

Conclusion

The management of ectopia cordis is a challenge for any obstetrician and pediatric surgeon due to its rarity. It causes mental agony and anxiety to the parents. With an early diagnosis, termination of pregnancy can be one of the options. Once it is diagnosed late, it needs a multidisciplinary approach, and the services of a very experienced pediatric surgeon to improve the prognosis.

A cruel invasion of Ewing's sarcoma of the skull: A rare case report

INTRODUCTION AND IMPORTANCE

Ewing's sarcoma, a highly malignant bone tumor, typically affects the pelvis and long bones of the lower extremities in children and young adults; primary involvement of the skull is rare. Primary Ewing's sarcoma arising from the skull is very rare. In most cases, this disease is fatal, although the prognosis of Ewing sarcoma improves with radiation and chemotherapy after surgery.

CASE PRESENTATION

This case is about 25-year-old woman who was referred to Omid Hospital in Urmia because of frequent headaches, where a tumor mass was found according to the results of CT scan. Biopsy confirmed small round cell sarcoma as the diagnosis. Chemotherapy was ineffective and tumor growth was unstoppable, causing the patient to die after 3 months.

CLINICAL DISCUSSION

Ewing's sarcoma can affect various parts of the human body, including bone and soft tissue, but rarely the skull. Ewing's sarcoma typically grows extradural and often reaches a very large size before invading the skull or being detected clinically.

CONCLUSION

In most cases, Ewing's sarcoma is fatal, although the prognosis of this disease improves with radiation and chemotherapy after surgery.

Invasion of undifferentiated pleomorphic sarcoma (UPS) in breast tissue; a case report study

INTRODUCTION AND IMPORTANCE

Breast sarcomas are scarce, histologically heterogeneous with nonepithelial malignancies that originate from the connective tissue within the parenchyma of breast. They can develop primarily, after radio-therapy (RT), or secondary due to chronic condition, including metastatic cancers.

CASE PRESENTATION

The present case report concerns 58-year-old women which was unbeknown to her malignancy in the early stages, until the mass became substantial in size. Chemotherapy and also radiotherapy were not effective, and the growth of tumor could not be prevented which the patient eventually died, due to respiratory complications.

CLINICAL DISCUSSION

Breast sarcomas are categorized in very rare malignancies, and the mortality of these types of cancers are significantly high as they often are not diagnosed in early stages. Based on the location and condition of the malignant tumor, therapeutic methods considered as chemotherapy, radiotherapy, and surgery.

CONCLUSION

In advance stages of breast sarcoma, chemotherapy, radiotherapy, and even surgery cannot be effectual. Therefore, periodical evaluation of breast wellness by diagnostic methods are recommended to all adult women.

Prevalence of Asymptomatic Talar Bone Marrow Edema in Professional Ballet Dancers: Preliminary Data From a 2-Year Prospective Study

Background

Compared with symptomatic bone marrow edema (BME) associated with stress fractures, asymptomatic BME seen on magnetic resonance imaging (MRI) is a phenomenon that has been described in high-level athletes and is thought to be related to bone adaptation to biomechanical loading unique to each sport. However, the prevalence, natural history, and management of these lesions remain poorly understood, particularly in dance, which places tremendous stress on the feet and ankles.

Purposes/Hypothesis

The purposes of this study were to (1) determine the prevalence of asymptomatic BME in the talus before the start of the performance season, (2) identify contributing demographic and training factors, and (3) compare the radiological evidence of talar BME with validated functional foot and ankle scores. We hypothesized that talar BME would be highly prevalent among asymptomatic professional dancers.

Study Design

Case series; Level of evidence, 4.

Methods

A total of 14 professional ballet dancers (6 female and 8 male; mean age, 24 years) were included in this 2-year prospective study. For each participant, we recorded complete medical and surgical history along with scores on the Foot and Ankle Ability Measure (FAAM) and the Foot and Ankle Disability Index. Bilateral foot and ankle 3.0-T MRI scans without contrast were completed before the start of the performance season and were evaluated for BME of the talus using the Fredericson criteria.

Results

Evidence of talar BME was seen in 15 of the 28 (54%) ankles examined and in 9 of 14 (64%) dancers. We found that 6 dancers demonstrated bilateral talar BME, 3 dancers demonstrated unilateral BME, and 5 dancers demonstrated no evidence of BME. The most common location of BME was the posterior talus, seen in 8 of 15 (53%) ankles. No statistically significant differences were noted in dancers with versus those without talar BME with regard to functional scores, demographic characteristics, or weekly training hours.

Conclusion

Asymptomatic talar BME was highly prevalent (64%) in professional ballet dancers and tended to occur posteriorly. Long-term clinical and radiographic follow-up is necessary to determine the natural history of these lesions.

Undifferentiated soft-tissue sarcoma (STS) in a 34-year-old woman: A case report

INTRODUCTION AND IMPORTANCE: soft tissue sarcoma (STS) is a type of cancer that can affect connective tissue. Diagnosis of this malignant tumor is difficult, and complications are related to the pressure it can exert on surrounding body organs. Up to 50 % of STS patients develop metastatic disease, which greatly affects the prognosis and is challenging for the treating physician.

CASE PRESENTATION

This case report is about a 34-year-old woman who was found to have significant growth of malignant tumor in her lower back due to misdiagnosis and negligence about her disease. After the cancer invaded the abdominal cavity, she died from related complications.

CLINICAL DISCUSSION

STS are among the rare malignant tumors, and the mortality rate of these cancers is very high because they are often not properly diagnosed.

CONCLUSION

Educating medical personnel, especially primary care physicians, about the symptoms and manifestations of STS can make a significant contribution to successful treatment. Due to the complexity of treatment, any soft-tissue swelling suspected of malignancy is best referred directly to a sarcoma center, where therapeutic management is carefully planned by an experienced multidisciplinary team.

Large wound surgery of diabetic foot ulcer with Split-thickness skin graft (STSG), and maggot debridement therapy (MDT): A case report

INTRODUCTION AND IMPORTANCE

Diabetic foot ulcers (DFUs) as one of the complications of diabetes mellitus (DM) can lead to death.

CASE PRESENTATION

The present case reports a 56-year-old woman with an 11-year history of type 2 diabetes who has had left DFUs for two years. The patient had antibiotic-resistant DFUs her left foot, which were completely gangrenous and a superficial ulcer up and under her left foot. Despite the routine DFU care, the patient did not recover from DFU using standard methods. The patient was referred to our wound management team. DFU was treated and managed using split-thickness skin graft (STSG) and surgical debridement, maggot debridement therapy (MDT). After two months, the patient's DFUs healed, and he was discharged from our service in good condition.

CLINICAL DISCUSSION

DFU can lead to infection, amputation, and even patient death. Therefore, effective treatment methods are very important for managing DFUs.

CONCLUSION

This case report study was shown that the combined use of STSG, surgical debridement, and MDT is a safe and effective approach to improve the healing of DFUs and prevent foot amputation.

Surgical debridement and maggot debridement therapy (MDT) bring the light of hope to patients with diabetic foot ulcers (DFUs): A case report

Introduction and importance

Management of diabetic foot ulcers (DFUs), one of the complications of diabetes mellitus, can lead to death and amputation, and it is one of the most critical challenges for the patients and their families.

Case presentation

The present case report concerns a 72-year-old man with a 5-year history of uncontrolled type 2 diabetes mellitus. The patient had antibiotic-resistant DFUs on two phalanges of his left foot, which were completely gangrenous, and a superficial ulcer of 1 × 1 cm under his left foot. Despite the routine DFU care, the phalanges of his DFU were amputated. The patient was moved to our wound management team. DFU was treated and managed using surgical debridement and maggot debridement therapy. Ten sessions of Maggot Debridement Therapy (MDT) were conducted (one therapy session every 48 h). After three months, the patient's DFUs healed, and he was discharged from our service in good condition.

Clinical discussion

DFU can lead to infection, amputation, and even patient death. Therefore, effective treatment methods are very important for managing DFUs.

Conclusion

Using surgical debridement and MDT is a safe and effective approach to facilitate the healing of DFUs.

•

Management of diabetic foot ulcers (DFUs) is one of the most critical challenges for the patients.

•

Diabetic foot ulcers do not respond to standard drug therapies.

•

Surgical debridement and Maggot Debridement Therapy (MDT) can manage diabetic foot ulcers.

Abdominopelvic MR to CT registration using a synthetic CT intermediate

Accurate coregistration of computed tomography (CT) and magnetic resonance (MR) imaging can provide clinically relevant and complementary information and can serve to facilitate multiple clinical tasks including surgical and radiation treatment planning, and generating a virtual Positron Emission Tomography (PET)/MR for the sites that do not have a PET/MR system available. Despite the long‐standing interest in multimodality co‐registration, a robust, routine clinical solution remains an unmet need. Part of the challenge may be the use of mutual information (MI) maximization and local phase difference (LPD) as similarity metrics, which have limited robustness, efficiency, and are difficult to optimize. Accordingly, we propose registering MR to CT by mapping the MR to a synthetic CT intermediate (sCT) and further using it in a sCT‐CT deformable image registration (DIR) that minimizes the sum of squared differences. The resultant deformation field of a sCT‐CT DIR is applied to the MRI to register it with the CT. Twenty‐five sets of abdominopelvic imaging data are used for evaluation. The proposed method is compared to standard MI‐ and LPD‐based methods, and the multimodality DIR provided by a state of the art, commercially available FDA‐cleared clinical software package. The results are compared using global similarity metrics, Modified Hausdorff Distance, and Dice Similarity Index on six structures. Further, four physicians visually assessed and scored registered images for their registration accuracy. As evident from both quantitative and qualitative evaluation, the proposed method achieved registration accuracy superior to LPD‐ and MI‐based methods and can refine the results of the commercial package DIR when using its results as a starting point. Supported by these, this manuscript concludes the proposed registration method is more robust, accurate, and efficient than the MI‐ and LPD‐based methods.

Extensive excisional surgery; the last hope for a patient with human papillomavirus-associated severe head and neck squamous cell carcinoma: A case report

Introduction and importance

Cutaneous squamous cell carcinoma (CSCC) is one of the most common malignant tumors of skin cancer. Most of these cancers occur on the head and neck. CSCC makes up the seventh most common type of cancer worldwide. The incidence of human papillomavirus (HPV)-associated head and neck squamous cell carcinoma became more prevalent, and HPV infection is mainly linked to head and neck squamous cell carcinoma (HNSCC).

Case presentation

A 57-year-old non-smoking man was admitted to Omid Hospital in Urmia, West Azerbaijan, Iran; there were extensive bleeding masses on his head and neck due to squamous cell carcinoma (SCC), and he has been diagnosed with HPV infection so accidentally. The operation room had prepared for excisional treatment and the masses had been removed as much as possible. Patient was referred to the wound care team to receive advanced treatment interventions.

Clinical discussion

Incidence of HPV-associated HNSCC has been more noticeable recently, and HPV infection alone can be a distinct risk factor for metastatic HNSCC. Most patients with HPV positive have peripheral lymph node involvement. Radiation therapy and surgery can offer equally good long-term results in small initial head and neck tumors. Traditionally, advanced head and neck tumors managed surgically more advantageous.

Conclusion

This case illustrates that history of HPV positive can be associated with a more severe and resistant type of HNSCC with poor treatment outcomes. Patients with HPV should be monitored regularly for HNSCC, and treatment should be started as soon as possible for a better result.

•

Cutaneous squamous cell carcinoma (CSCC) is one of the most common malignant tumors of skin cancer.

•

Approximately 80% of cutaneous squamous cell carcinoma (CSCC) occur on the head and neck.

•

The human papillomavirus (HPV) is a third risk factor for head and neck carcinogenesis.

•

Advanced head and neck tumors are managed surgically is more advantageous.

Radiographic Templating for Calcaneus Operative Fixation: How Similar Is Side-to-Side Comparison?

OBJECTIVES

Calcaneal fractures often require contralateral, uninjured calcaneus radiographs as a template. The purpose of this study was to establish mean values for calcaneal radiographic parameters in an uninjured urban American population and perform side-by-side comparison with respect to age, sex, laterality, and radiograph obliquity (XRO).

DESIGN

Retrospective analysis of consecutive patients.

SETTING

Fourteen hospitals including Level 1 trauma center.

PATIENTS/PARTICIPANTS

Retrospective review of >800 uninjured patients with bilateral foot and calcaneus radiographs obtained between June and December 2019 was performed. Inclusion criteria were the following: age 18-89 years without fracture; previous foot surgical procedures; radiographic evidence of arthrosis in ankle, hindfoot, or midfoot; osteomyelitis; tumor; or foot deformities.

INTERVENTION

The lateral radiographs were independently reviewed by 3 observers, measuring Böhler angle (BA), crucial angle of Gissane (CAG), calcaneal length (CL), calcaneal height (CH), calcaneotalar ratio (CTR), and XRO.

MAIN OUTCOME MEASUREMENTS

The mean values of BA, CAG, CL, CH, and CTR were established. Side-by-side comparisons were completed with respect to age, sex, laterality, and XRO.

RESULTS

There were no statistically significant differences in side-by-side measurements of the BA, CAG, CL, or CH. XRO had significant effects on the measurements of BA, CAG, CH, and CTR. Side-by-side comparisons showed greater intersubject variability than within-subject differences.

CONCLUSIONS

We did not observe any differences in commonly measured calcaneal radiographic parameters. CAG is not a reliable parameter for diagnostic and operative planning purposes. We conclude that the use of contralateral calcaneus radiographs as templates for calcaneus fractures is a valid technique.

Cyclopia, a newborn with a single eye, a rare but lethal congenital anomaly: A case report

Introduction and importance

Cyclopia is a rare congenital disorder characterized by facial abnormalities. In this condition, the orbits of the eye are not properly divided into two cavities so that they can be seen either as a single eye field or two bilateral fields that are very close to each other. This syndrome affects the embryos that are either aborted or stillborn upon delivery or, at best, die shortly after birth.

Case presentation

This case report is of a 37-week- and 5-day-old female fetus with a birth weight of 2300 g, a height of 43 cm, and a head circumference of 31 cm. She was born to a 44-year-old mother through normal vaginal delivery at Mahzad Hospital, Urmia, Iran. In the physical examination, an eye and a 4-cm proboscis were seen in the middle of the forehead. The newborn also had no nose, and his outer ears were normal. No cleft lip or cleft palate was observed. Unfortunately, the newborn expired 13 h after birth.

Clinical discussion

Cyclopia leads to a stillbirth since the brain and other parts of the body do not grow normally in fetuses with this disorder. Moreover, it can be diagnosed using ultrasonography while the fetus is growing inside the uterus.

Conclusion

Early diagnosis during pregnancy using diagnostic methods and proper management of this abnormality should be emphasized to prevent further harm to the newborn and the mother with this syndrome. Moreover, many of these newborns should be offered early neonatal palliative care.

•

Cyclopia is a rare congenital disorder with life-threatening complications.

•

Cyclopia mostly affects the embryos that are either aborted or stillborn.

•

Early diagnosis during pregnancy should be emphasized to prevent its complications.

•

Prenatal palliative care emphasizes the importance of planning for the experience of losing an infant.

•

Parental involvement in end-of-life care for their infant is an important aspect of neonatal palliative care.

Ozone therapy as an alternative method for the treatment of diabetic foot ulcer: a case report

Background

Diabetic foot ulcer (DFU) is one of the most important complications of diabetes that can lead to amputation. Treatment of DFUs is a major challenge and places a heavy economic and social burden on patients and their families.

Case presentation

The present case report is of a 52-year-old kurdish male patient with a 7-year history of type 2 diabetes. While on a bike ride, he sustained a traumatic injury to his right leg, which caused a deep gash measuring 14 × 5 cm on the tibia. During the hospital stay, no improvement was observed after routine wound care including suturing, antibiotic therapy, and dressing change. The patient was referred to our wound-care team. In the first step, the necrotic tissues of his foot ulcer were irrigated and then debrided using mechanical debridement and saline. Next, the patient underwent a 70 μg/dL dose of ozone therapy over a 30-day period in 10 sessions (one 20-minute session every 3 days). Between each session, the patient's wound was wrapped in silver-containing gauze bandages. After 1 month of wound-care using ozone therapy, the patient's foot ulcer had healed and he was discharged from our wound-care service with a stable and good general condition.

Conclusion

Considering the effectiveness of ozone therapy along with silver-containing dressing in the treatment of DFUs, wound-care teams can utilize it as an adjunct to the standard methods of DFU treatment.

Hyaline fibromatosis syndrome: A rare case of multifocal intra-articular involvement

Hyaline fibromatosis syndrome (HFS) is a rare, progressive, autosomal recessive disorder that presents with connective tissue deposition of amorphous hyaline material within the musculocutaneous tissue and/or visceral organs. HFS presents clinically in infancy or early childhood and can result in severe disability and life threatening complications. Given the rarity of the disorder, the imaging characteristics of HFS are seldom described in the literature. We describe a case of a 25-year-old patient presenting with bilateral knee pain, limited range of motion in her extremities, and lower extremity weakness with detailed MR imaging demonstrating the first case of multifocal intra-articular deposition of hyaline material within several joints.

Multidisciplinary approach for repeat musculoskeletal lesion biopsy after nondiagnostic initial sampling: A 10-year single-center experience

BACKGROUND AND OBJECTIVES

Success rates for initial image-guided biopsy of musculoskeletal (MSK) lesions have been well documented; evidence regarding success rates for repeat biopsy following initially nondiagnostic (ND) image-guided biopsy of MSK lesions is more limited. This study evaluates the outcomes of repeat computerized tomography-guided MSK biopsies following ND biopsies using a multidisciplinary approach.

MATERIALS AND METHODS

Electronic medical record search covering a 10-year period identified patients that received two or more biopsies for an MSK tumor or tumor-like process. The decision for initial and repeat image-guided biopsy of each lesion was made following multidisciplinary MSK tumor board review. Lesion location, histopathology results, size of biopsy needle when available, and change in technique between biopsy attempts was documented.

RESULTS

Repeat biopsy rate was 1.6%. 23 patients with repeat MSK biopsy were identified. A total of 17 of 23 (74%) repeat biopsy attempts were diagnostic. A total of 22 of 23 (96%) repeat biopsy attempts were clinically useful. Diagnostic repeat biopsies were described as employing one or more of five technical differences compared to the first biopsy attempt, the most common being improved targeting of the lesion itself.

CONCLUSIONS

A multidisciplinary approach may yield improved repeat-biopsy rates and clinical utility of repeat MSK biopsies compared to prior reports.

Appendicular skeleton MRI in multiple myeloma: Utility and clinical implications

e19527

Background: Skeletal MRI plays an integral role in diagnosing Multiple Myeloma and, in many cases, dictates need for treatment. While axial skeleton MRI is performed with established clinical utility, appendicular MRI is performed sparingly with utility not fully ascertained. We aim to assess the utility of appendicular MRI while establishing clinical factors which may predict outcomes. Methods: 107 appendicular skeleton MRIs were included for retrospective analysis over 15 years. No statistically significant age or gender related variability was noted. Variables including patient age, diagnosis, disease stage/activity, indication, transplant status, MRI result, treatment course, and survival were analyzed via Likelihood Ratio Chi-Square test or logistic regression. Results: Patient age, disease stage, presence of active marrow disease, history of relapse, and presence of axial or appendicular osseous disease were found to have a statistically significant correlation with MRI result. Disease stage and presence of active hematologic disease correlated with post MRI management alterations. Additionally, presence of active hematologic disease at time of MRI demonstrated a correlation with post MRI management strategy. Furthermore, MRI result was a predictor of downstream development of additional skeletal lesions. Interestingly, MRI result was not a predictor of survival. Conclusions: Several parameters may be used to determine a clinical pre-test probability of appendicular disease at the time of MRI. In addition, these clinical parameters and MRI results correlate with trends in subsequent patient treatment strategies. [Table: see text]

MRI of acquired Brown syndrome: a report of two cases

Brown syndrome is characterized by upward gaze impairment while the eye is in adduction. It is caused by abnormalities involving the superior oblique tendon-trochlea complex. Imaging can help confirm the diagnosis, shed light on its etiology, and determine the best course of treatment. However, reports of magnetic resonance imaging findings of acquired Brown syndrome are scarce in the literature. Here, we describe magnetic resonance imaging features of 2 cases of acquired Brown syndrome.

Nanoscale electromechanical and electronic properties of free-standing ZnO nano- and microstructured platelets

The piezoelectric response, conductivity and surface potential of individual grains and grain boundaries in free-standing polycrystalline ZnO nano- and microstructured platelets is studied using scanning probe based techniques on the nanoscale. We find that applied dc electric fields can alter the piezoresponse in individual grains, as well as the local nanoscale conductivity, and invert the relative surface potential at grain boundaries. This can be attributed to defect accumulation at the grain surfaces and at grain boundaries and the associated density of carriers. Together with recently observed below-bandgap photoconductivity at grain boundaries, the presented observation opens new venues for potential nanoelectronic applications that rely on grain and grain boundary engineering and functionality in a wide-bandgap transparent material.
