Abstract:

Purpose. Intracavernosal self-injection (ICI) was first described in 1982, and remains a viable therapy for erectile dysfunction. However, intracorporal needle breakage can be a rare complication of therapy. We report a rare complication of intracorporal needle breakage and a retention of a 30-gauge needle in a 42-year-old paraplegic man. We discuss our experience in using portable high-frequency ultrasound intraoperatively to visualize and guide removal of a retained ICI needle.Materials and Methods. Review of case and ultrasound technique are presented.Results. Using intraoperative ultrasound imaging, the retained intracorporal needle was successfully removed from the patient's penis without any complications. Follow-up ultrasonography and X-ray confirmed complete removal of the needle.Conclusions. We report on the successful implementation and use of a portable high-frequency ultrasound probe to visualize a retained intracorporal needle inside the penis and its use to guide removal. Given the rapid proliferation of portable ultrasound machines in the operating room and out in the field, we expect these imaging techniques to become routine, especially in urological emergencies.

Abstract:

Introduction An increasing quantity of data is required to guide precision medicine and advance future healthcare practices, but current analytical methods often become overwhelmed. Artificial intelligence (AI) provides a promising solution. Plastic surgery is an innovative surgical specialty expected to implement AI into current and future practices. It is important for all plastic surgeons to understand how AI may affect current and future practice, and to recognise its potential limitations. Methods Peer-reviewed published literature and online content were comprehensively reviewed. We report current applications of AI in plastic surgery and possible future applications based on published literature and continuing scientific studies, and detail its potential limitations and ethical considerations. Findings Current machine learning models using convolutional neural networks can evaluate breast mammography and differentiate benign and malignant tumours as accurately as specialist doctors, and motion sensor surgical instruments can collate real-time data to advise intraoperative technical adjustments. Centralised big data portals are expected to collate large datasets to accelerate understanding of disease pathogeneses and best practices. Information obtained using computer vision could guide intraoperative surgical decisions in unprecedented detail and semi-autonomous surgical systems guided by AI algorithms may enable improved surgical outcomes in low- and middle-income countries. Surgeons must collaborate with computer scientists to ensure that AI algorithms inform clinically relevant health objectives and are interpretable. Ethical concerns such as systematic biases causing non-representative conclusions for under-represented patient groups, patient confidentiality and the limitations of AI based on the quality of data input suggests that AI will accompany the plastic surgeon, rather than replace them.

"Acetabular Subchondral and Cortical Breach During Labral Repair with Suture Anchors: Influence of Portal Location, Curved vs Straight Drill Guides, and Drill Starting Point." Orthopaedic Journal of Sports Medicine 7, no. 7_suppl5 (July 2019): 2325967119S0037. http://dx.doi.org/10.1177/2325967119s00373.

Abstract:

Objectives: Acetabular labral tears are commonly treated with arthroscopic repair using suture anchors. Iatrogenic chondral injury has been cited as one of the more common complications during hip arthroscopy, and can occur while pre-drilling for suture anchors. Proposed factors contributing to penetration of the articular subchondral bone or the far cortex of the acetabulum include the portal utilized for drilling; the position of the drill guide relative to the acetabular rim (on rim, ON; off rim, OFF); and the use of straight (ST) versus curved (CU) drill guides. The purpose of this study was to evaluate the relative impact of these variables on drill penetration of the acetabular subchondral bone or the far cortex of the acetabulum. Methods: Sixty sawbone acetabula models were marked at the 3, 2, 1, 12, and 11 o’clock position. A Simulated anterior (AP), anterolateral (AL), and distal anterolateral accessory (DALA) portals were created. Twelve groups of five acetabula were drilled at each clock face position: ST/AP/ON; ST/AL/ON; CU/AP/ON; CU/AL/ON; ST/AP/OFF; ST/AL/OFF; CU/AP/OFF; CU/AL/OFF; ST/DALA/ON; ST/DALA/OFF; CU/DALA/ON; CU DALA/OFF. Perforations of the articular subchondral bone and far cortex of the acetabulum were recorded. Results were tabulated and analyzed to assess the relative impact of each variable both in aggregate and at each position on the clock face. Results: A total of 300 acetabular suture anchor drill holes were created on 60 acetabula 12 combinations of portal utilized (anterior, anterolateral, distal anterolateral accessory), drill guide type (curved or straight), and rim position (on rim, off rim). A total of 38/300(12.7%) drillings perforated the subchondral bone, and 45/300(15%) breach the far cortex. Drilling from the AP, AL, and DALA portal breached the articular subchondral bone 21/100 (21%), 17/100(17%), and 0/100(0%) respectively; and breached the far acetabular cortex 36/100(36%), 1/100(1%), and 8/100(8%) respectively. Drillings using a curved drill guide penetrated the subchondral bone on 14/150(9.3%) attempts and drillings using a straight drill guide penetrated the subchondral bone 33/150(22%) attempts (p=0.0025). Drillings with an “On Rim” start point breached the articular subchondral bone 29/150(19.3%) versus 9/150(6%) for drillings with an “Off Rim” start point; and breached the far acetabular cortex 21/150(14%) times versus 24/150(16%) times. Articular surface penetrations were most frequent at the 2 and 3 o’clock positons, and far cortex perforations were most frequent at the 11 and 12 o’clock positions. Conclusion: This study quantifies the relative impact of portal location, drill guide, and starting point on the acetabular rim on acetabular subchondral bone and far cortex penetration. Portal location had the highest impact, with the DALA portal noted to be the safest. Curved drill guides also reduced the number of acetabular subchondral bone penetrations. These findings can be used to influence arthroscopic technique during acetabular labral repair.

Abstract:

BackgroundTraining nurses in ultrasound-guided peripheral intravenous catheter placement might reduce the use of more invasive venous access devices (peripherally inserted central catheters (PICC) and midline catheters).MethodsWe implemented an abbreviated training in ultrasound-guided peripheral intravenous catheter placement for nurses on an inpatient medical unit and provided a portable ultrasound device for 10 months.ResultsNurses on this unit placed 99 ultrasound-guided peripheral intravenous catheters with a high level of success. During the implementation period, PICC and midline catheter placement decreased from a mean 4.8 to 2.5 per month, meeting criteria for special cause variation. In the postimplementation period, the average catheter use reverted to 4.3 per month on the intervention unit. A comparison inpatient medical unit without training or access to a portable ultrasound device experienced no significant change in PICC and midline catheter use throughout the study period (mean of 6.0 per month).ConclusionsThese results suggest that an abbreviated training in ultrasound-guided peripheral intravenous catheter placement for nurses on an inpatient medical unit is sufficient to reduce PICC and midline catheters.

Abstract:

We describe a case report and technique for using a portable ultrasound scanner and a curvilinear transducer (4-5MHz) (SonoSite Micromaxx SonoSite, Inc. 21919 30th Drive SE Bothwell W. A.) to guide sacroiliac joint (SIJ) injection. A 42-year-old male presented with chronic lower back pain centered on his left SIJ. His pain averaged 7 out of 10 (numerical rating scale). For the ultrasound-guided SIJ injection the patient was placed in the prone position. The ultrasound transducer was oriented in a transverse orientation at the level of the sacral hiatus. Here the sacral cornuae were identified. Moving the transducer laterally from here, the lateral edge of the sacrum was identified. This bony edge was followed in a cephalad direction with the transducer maintained in a transverse orientation. A second bony contour, the ileum, was identified. The cleft between both bony contours represented the sacroiliac joint. This was found at 4.5 cm depth. Real-time imaging was used to direct a 22G spinal needle into the SIJ, where solution was injected under direct vision. The patient’s pain intensity decreased to a 2 out of 10 (numerical rating scale). Function improved and the patient was able to return to work. These improvements were maintained at 16 weeks. Ultrasound guidance does not expose patients and personnel to radiation and is readily accessible. Ultrasound-guided SIJ injections may have particular applications in the management of chronic lower back pain in certain clinical scenarios (e.g. pregnancy). Future studies to demonstrate efficacy and reproducibility are needed. Key words: Technique, visualization, real-time, ultrasound, sacroiliac joint.

Abstract:

Purpose: This article is the first of 2 that present basic guidelines for audiologists to provide clinical management of tinnitus. The method, termed audiologic tinnitus management (ATM), was developed to incorporate management strategies that can be implemented most efficiently by audiologists. Method: Development of ATM has been drawn from the clinical and research experience of the authors and numerous audiologists. Certain elements of ATM are adapted from the methods of tinnitus masking and tinnitus retraining therapy. Procedures are described in the present article for performing the intake assessment, while the companion article (J. A. Henry, T. L. Zaugg, & M. A. Schechter, 2005) describes treatment methodology. Results: Development of ATM has resulted in defined procedures to conduct a basic tinnitus assessment that includes written questionnaires, an intake interview, audiologic evaluation, and a psychoacoustic assessment of tinnitus perceptual characteristics. If patients report a sound tolerance problem (hyperacusis), loudness discomfort levels are measured at audiometric frequencies. There are special procedures for selecting hearing aids, ear-level noise generators, combination devices (noise generator and hearing aid combined), and personal listening devices (i.e., portable radios and tape, CD, and MP3 players). Conclusions: This article explains each of these assessment components in detail. Adoption of the ATM assessment protocol by audiologists can contribute to the establishment of uniform procedures for the clinical management of tinnitus patients.

Abstract:

Mobile and handheld mapping systems are becoming widely used nowadays as fast and cost-effective data acquisition systems for 3D reconstruction purposes. While most of the research and commercial systems are based on active sensors, solutions employing only cameras and photogrammetry are attracting more and more interest due to their significantly minor costs, size and power consumption. In this work we propose an ARM-based, low-cost and lightweight stereo vision mobile mapping system based on a Visual Simultaneous Localization And Mapping (V-SLAM) algorithm. The prototype system, named GuPho (Guided Photogrammetric System), also integrates an in-house guidance system which enables optimized image acquisitions, robust management of the cameras and feedback on positioning and acquisition speed. The presented results show the effectiveness of the developed prototype in mapping large scenarios, enabling motion blur prevention, robust camera exposure control and achieving accurate 3D results.

Abstract:

This paper reports the results of a multi-national survey in several different countries on the attitudes, requirements and preferences of blind and visually impaired people for a robotic guide. The survey is introduced by a brief overview of existing work on robotic travel aids and other mobile robotic devices. The questionnaire comprises three sections on personal information about respondents, existing use of mobility and navigation devices and the functions and other features of a robotic guide. The survey found that respondents were very interested in the robotic guide having a number of different functions and being useful in a wide range of circumstances. They considered the robot's appearance to be very important but did not like any of the proposed designs. From their comments, respondents wanted the robot to be discreet and inconspicuous, small, light weight and portable, easy to use, robust to damage, require minimal maintenance, have a long life and a long battery life.

Abstract:

With the merge of digital television (DTV) and the exponential growth of broadcasting network, an overwhelmingly amount of information has been made available to a consumer's home. Therefore, how to provide consumers with the right amount of information becomes a challenging problem. In this paper, we propose an electronic programming guide (EPG) recommender based on natural language processing techniques, more specifically, text classification. This recommender has been implemented as a service on a home network that facilitates the personalized browsing and recommendation of TV programs on a portable remote device. Evaluations of our Maximum Entropy text classifier were performed on multiple categories of TV programs, and a near 80% retrieval rate is achieved using a small set of training data.

Methods Breast cancer detection by IP was performed to guide biopsy, in particular open biopsy, or help fine-needle or core-needle positioning when the main guidance method was ultrasonography or digital radiography. 99mTc Sestamibi (MIBI) was injected 1 h before imaging and biopsy to 14 patients with suspected or known breast cancer. Scintigraphic images were acquired before and after biopsy in each patient. The surgeon was allowed to take into account scintigraphic images as well as previously performed mammograms and ultrasonography. Results High-resolution IP images were able to guide biopsy toward cancer or toward washout zones of cancer, which are thought to be chemoresistant, in seven patients out of 10. Four patients in whom IP and MIBI were unable to guide biopsy were found not to have cancer. Conclusions Our study confirms the ability of IP to guide breast biopsy even when our minicamera has to be handled manually by trained physicians during surgery.

Abstract:

Inspired by the fundamental mechanics of an ancient whirligig (or buzzer toy; 3300 BC), a hand-driven rotational triboelectric nanogenerator (HDR-TENG) was designed and optimised, guided by our recently reported mathematical modelling. This modelling indicates that the power generated by HDR-TENG is a function of the number of segments, rotational speed, and tribo-surface spacing with different weighting sensitivities. Based on the simulation results, additive manufacturing technology was combined with commercially available components to cost-effectively fabricate the HDR-TENG. The fabricated HDR-TENG can provide stable and adjustable rotational speed up to 15,000 rpm with a linear hand stretching. The output voltage of HDR-TENG maintains a constant value within 50,000 cycles of testing when using Nylon 66 and PTFE as the triboelectric material. It can charge a 47 μF capacitor to 2.2 V in one minute. This study provides a cost-effective portable HDR-TENG device with adjustable high rotational speed, high power output, and long durable life, creating opportunities to provide a power supply for point-of-care devices in remote or resource-poor settings and applications in science and engineering education.

Abstract:

Aims and Background When removal of osteoid osteoma is performed with open biopsy, the surgeon can be guided by radioactivity of 99mTc-MDP (methylene D- phosphonate) acquired by a probe. Material and methods We compared the performance of a commercially available ZnCdTe probe (Neoprobe 2000) and a one-square-inch-field-of-view imaging probe (IP) on two patients undergoing open biopsy for osteoid osteoma. Triphasic bone scintigraphy was performed before operation and Neoprobe as well as IP were used in the operating room by two nuclear physicians. When the surgeon asked for guidance, each nuclear physician had to indicate a precise direction. Results The surgeon asked for guidance once in the first operation, on a patient with osteoid osteoma of the femur, and four times in the second operation, for osteoid osteoma of the acetabulum. The indications provided by IP were correct 5/5 times, whereas the commercial probe was correct 3/5 times. Both devices were able to assess the surgical radicality. After biopsy, bone samples were divided into high-count and low-count samples. Pathological examination confirmed the presence of osteoid osteoma in high-count samples. Conclusions IP has already been used to guide biopsy, but only in breast disease. The present work confirms its good performance also in orthopedics as a portable mini gamma camera that can be used in the operating room.

Abstract:

Photodynamic therapy (PDT) has been commonly used in treating many diseases, such as cancer and infectious diseases. We investigated the different effects of PDT on three main pathogenic bacteria of periodontitis — Prevotella melaninogenica (P.m.), Porphyromonas gingivalis (P.g.) and Aggregatibacter actinomycetemcomitans (A.a.). The portable red light-emitting diode (LED) phototherapy device was used to assess the exogenous PDT effects with different light doses and photosensitizer concentrations (Toluidine blue O, TBO). The portable blue LED phototherapy device was used to assess the endogenous PDT effects with the use of endogenous photosensitizers (porphyrin) under different light doses. We found out that both exogenous and endogenous PDT were able to restrict the growth of all the three bacteria significantly. Moreover, the optimal PDT conditions for these bacteria were obtained through this in vitro screening and could guide the clinical PDT on periodontitis.

Abstract:

An 81-year-old woman who underwent percutaneous endoscopic gastrostomy (PEG) a year before, after cerebral infarction was receiving home medical care. The first accidental PEG tube removal occurred after clinic hours, and the home-care doctor visited her home to quickly reinsert the tube. After the narrowed fistula was dilated, the tube was reinserted with a guide wire. An X-ray taken with a CALNEO Xair, which is an easily portable X-ray system launched in 2018, confirmed that the tip of the PEG tube was successfully placed in the stomach. A similar accidental removal occurred 2 months later, and we managed it in the same way. Both events were resolved with a single radiograph without significant difficulty. With in-home medical care, PEG tube replacement can be performed easily and safely with a handy portable X-ray system.

Abstract:

Background. Intraoperative imaging for endourologic procedures is generally limited to single-plane fluoroscopic X-ray. The O-arm™ is a mobile cone-bean CT scanner that may have applications in urologic surgeries. Case Presentation. We present a case of an 85-year-old male with radiation cystitis and recurrent gross hematuria who was identified to have a bladder perforation on cystoscopy during emergent clot evacuation. Single-view fluoroscopic evaluation was inconclusive as to whether an intraperitoneal bladder perforation occurred. A portable cone-beam CT scan was used to acquire a 3-D CT cystogram, which demonstrated intraperitoneal contrast extravasation, confirming the diagnosis of an intraperitoneal bladder perforation. Conclusion. We report the first use of a portable cone-beam CT scanner to perform an intraoperative CT cystogram to diagnose an intraperitoneal bladder perforation and guide surgical management.

Abstract:

Point-of-care ultrasound (POCUS), realized by recent developments in portable ultrasound imaging systems for prompt diagnosis and treatment, has become a major tool in accidents or emergencies. Concomitantly, the number of untrained/unskilled staff not familiar with the operation of the ultrasound system for diagnosis is increasing. By providing an imaging guide to assist clinical decisions and support diagnosis, the risk brought by inexperienced users can be managed. Recently, deep learning has been employed to guide users in ultrasound scanning and diagnosis. However, in a cloud-based ultrasonic artificial intelligence system, the use of POCUS is limited due to information security, network integrity, and significant energy consumption. To address this, we propose (1) a structure that simultaneously provides ultrasound imaging and a mobile device-based ultrasound image guide using deep learning, and (2) a reverse scan conversion (RSC) method for building an ultrasound training dataset to increase the accuracy of the deep learning model. Experimental results show that the proposed structure can achieve ultrasound imaging and deep learning simultaneously at a maximum rate of 42.9 frames per second, and that the RSC method improves the image classification accuracy by more than 3%.

Abstract:

Patients with acute cholangitis require emergent biliary decompression. Those who are hemodynamically unstable on vasopressor support and mechanical ventilation are too critically ill to move outside of the intensive care unit. This prohibits performing Endoscopic Retrograde Cholangiopancreatography (ERCP) in the endoscopy unit. Fluoroscopic guidance is required to confirm deep biliary cannulation during ERCP. There are a few reported cases of bedside ERCP using portable C-arm fluoroscopy unit or ultrasound guided cannulation. We present a unique case of life-saving emergent bedside ERCP in a severely ill patient with cholangitis and septic shock, using simple portable X-ray to confirm biliary cannulation.

Abstract:

There is currently no objective portable screening modality for narrow angles in the community. In this prospective, single-centre image validation study, we used machine learning on slit lamp images taken with a portable smartphone device (MIDAS) to predict the central anterior chamber depth (ACD) of phakic patients with undilated pupils. Patients 60 years or older with no history of laser or intraocular surgery were recruited. Slit lamp images were taken with MIDAS, followed by anterior segment optical coherence tomography (ASOCT; Casia SS-1000, Tomey, Nagoya, Japan). After manual annotation of the anatomical landmarks of the slit lamp photos, machine learning was applied after image processing and feature extraction to predict the ACD. These values were then compared with those acquired from the ASOCT. Sixty-six eyes (right = 39, 59.1%) were included for analysis. The predicted ACD values formed a strong positive correlation with the measured ACD values from ASOCT (R2 = 0.91 for training data and R2 = 0.73 for test data). This study suggests the possibility of estimating central ACD using slit lamp images taken from portable devices.

Abstract:

Electrical grounding is an indispensable part of the power system network. The grounding system is mainly affected by grounding resistance and the nature of the soil. High ground resistance produces the phenomenon of soil ionization, surface arching, and back flashover. A conventional grounding system requires the deep digging of electrodes, thus creating maintenance difficulties. This research work focuses on the safe operation of an electric power system from external and internal impulses arising due to lightning strikes or short circuits. The study proposes an application of mineral samples as grounding materials, and bentonite is used as backfilling material in portable grounding systems. A detailed experimental analysis was conducted under controlled conditions to evaluate the performance of selected materials in high-resistance soil. The problem of a deeply driven electrode is addressed by designing the portable grounding system. The study results demonstrate that the proposed portable grounding system could be installed in troubled environments such as forests, deserts, and rocky terrains. To measure the breakdown voltages of the proposed samples, X-ray Diffraction (XRD) analysis and other laboratory tests were conducted. The electric field intensities are extracted through Finite Element Analysis (FEA). The experimental and simulation findings show the expected performance of mineral samples under various operating conditions. The findings of this study can guide the practitioners for safe and efficient operations of portable electrical grounding systems.

The author discusses key findings of a series of video walks developed as part of her practice-based PhD research (2011–2014). Four video walks were produced for handheld projectors and tested in four different public spaces. The first video walks ( The Surface Inside, 2011; I-Walk, 2012) were guided, and only one handheld projector was available. The latter ( Walk-itch, 2013; (wh)ere land, 2014) were created for multiple handheld projectors, offering participants a cocreative role. Onsite observations revealed a shift in participant engagement between earlier and later video walks. A threefold method for analyzing audiovisual documentation also emerged during the research.
