Detecting the corneal neovascularisation area using artificial intelligence.

Aims: To create and assess the performance of an artificial intelligence-based image analysis tool for the measurement and quantification of the corneal neovascularisation (CoNV) area.

Methods: Slit lamp images of patients with CoNV were exported from the electronic medical records and included in the study. An experienced ophthalmologist made manual annotations of the CoNV areas, which were then used to create, train and evaluate an automated image analysis tool that uses deep learning to segment and detect CoNV areas.

Promoting Less Complex and More Honest Price Negotiations in the Online Used Car Market with Authenticated Data.

Online peer-to-peer (P2P) sales of used and or high-value goods are gaining more and more relevance today. However, since potential buyers cannot physically examine the product quality during online sales, information asymmetries and consequently uncertainty and mistrust that already exist in offline sales are exacerbated in online markets. Authenticated data platforms have been proposed to solve these problems by providing authenticated data about the negotiation object, integrating it into text-based channels secured by IT.

Comparing Reasons for Starting and Stopping Methadone, Buprenorphine, and Naltrexone Treatment Among a Sample of White Individuals With Opioid Use Disorder.

Objectives: Despite their efficacy, medications for opioid use disorder (MOUD) are underutilized in the United States. Nonetheless, few studies have explored reasons why individuals choose to start MOUD or discontinue MOUD after starting, especially extended-release naltrexone. We sought to identify reasons why individuals start and stop MOUD, including the differences between starting and stopping the 3 most common formulations: methadone, sublingual buprenorphine, and extended-release naltrexone.

The role of 18F fluorodeoxyglucose positron emission tomography (18F-FDG-PET) in children with rheumatic carditis and chronic rheumatic heart disease.

Background: We report the use of positron emission tomography (PET) using 18F-FDG for the diagnosis of carditis in children with rheumatic heart disease (RHD).

Material And Methods: Thirty-six children aged 6-17 years (seventeen males and nineteen females) with isolated rheumatic significant mitral regurgitation (MR) underwent FDG-PET scanning of the heart after fasting for 6 h within a period of 2 years. They were divided into two groups based on Jones criteria - acute rheumatic carditis and chronic RHD.

Current developments in French ethnopsychoanalysis.

French ethnopsychoanalytic approaches to therapy with immigrants combine the psychoanalytical interest in subjectivity with a specific concern for cultural factors and with the role migration plays as a crucial life event. Recent approaches consider culture as profoundly hybrid and use the notions of ''métissage'' and ''décentrage'' as central concepts. This article presents extracts from a qualitative study of ethnopsychoanalytic therapies with immigrant families.

Usefulness of 99mTc-pertechnetate single-photon emission computed tomography in remnant mass estimation of postsurgical patients of differentiated thyroid cancer during internal dosimetry.

Objective: No satisfactory methods exist for postsurgical remnant mass estimation required for dosimetric calculations in differentiated thyroid cancer patients undergoing I-131 remnant ablation. We estimated the remnant mass by Tc-99m pertechnetate single-photon emission computed tomography to calculate the radiation dose delivered.

Hepatobiliary scintigraphy in detecting lesser sac bile leak in postcholecystectomy patients: the need to recognize as a separate entity.

Cholecystectomy is one of the most commonly performed abdominal surgeries in which bile duct injury and bile leaks are the most important complications. Imaging plays an important role in the prompt diagnosis and management of bile leaks. The more common sites of bile leak are the gallbladder bed, subhepatic, in a bilioma, right paracolic gutter, or diffusely in the peritoneal cavity.

Evaluation of dysfunction and malformations of the urinary tract in patients with meningomyelocele, by renal dynamic scintigraphy and direct radionuclide cystography. An Indian perspective.

Meningomyelocele (MMC) is the most common form of neural crest closure defect and may be associated with dysfunction and malformations of multiple organs including urinary tract. It affects as many as 2-4 in 1000 live births, however there are no epidemiological studies available from India. Anatomical and neurogenic abnormalities of the urinary tract are known to occur in these patients.

Comparison between dobutamine stress and combination of handgrip exercise with dobutamine stress in myocardial perfusion SPECT.

Aim: We compared the efficacy, side effects of combined handgrip exercise and dobutamine stress with dobutamine stress alone during myocardial perfusion imaging in patients unable to exercise, and in whom vasodilator stress was contraindicated.

Methods: We studied 126 consecutive patients (89 male, 37 female; mean age 63+/-8 years) referred for dobutamine stress myocardial perfusion SPECT. Patients were divided into Group A (n=63), who underwent only dobutamine stress and group B (n=63) who were subjected to combined handgrip exercise and dobutamine infusion.

The ability of positron emission tomography to study various biologic processes opens up new possibilities for both research and day-to-day clinical use. Positron emission tomography has progressed rapidly from being a research technique in laboratories to a routine clinical imaging modality becoming part of armamentarium for the medical profession.

Adrenal and renal metastases from follicular thyroid cancer.

Patients with differentiated thyroid cancer may have asymptomatic involvement of renal and/or adrenal gland, particularly if they are elderly and have associated metastases to other organs, which may remain undetected if these patients are not subjected to radioiodine treatment. Our experience also emphasises the role of routine post-radioiodine therapy whole body scan with high degree of clinical suspicion, which may reveal lesions otherwise not discernable in low dose whole body scan. All suspicious lesions should be subjected to structural imaging like ultrasound, CT or MRI for confirmation.

Double epidural catheter with ropivacaine versus intravenous morphine: a comparison for postoperative analgesia after scoliosis correction surgery.

Background: Major spine surgery with a dorsal or ventrodorsal approach causes severe postoperative pain. The use of continuous epidural analgesia through one or two epidural catheters placed intraoperatively by the surgeon has been shown to provide efficient postoperative pain control. In this prospective unblinded study, the authors compared the efficacy of continuous intravenous morphine with a continuous double epidural catheter technique with ropivacaine after scoliosis correction.
