A new 3D CT image acquisition, visualization and measurement application software for interventional radiology procedures called SmartCT has been given clearance by the FDA. SmartCT that works with  Philips’ guided therapy system, Azurion, makes possible the removal of structures from the images that obstruct the region of interest and the selection and storage of optimum projection angles for recall during procedures.

A single-center, randomized, sham-controlled trial has demonstrated that endoscopic full-thickness plication performed with the new GERD-X device improved both symptoms and quality of life in patients with PPI–dependent GERD. The procedure also has the advantages that it has fewer side effects and a short procedure time. Improvements in GERD-HRQL score, heartburn symptom score and regurgitation symptom score were reported in the subjects who underwent the procedure. Over 60% of the subjects could discontinue the use of PPIs at 12 months.

Accelerated approval has been granted to pembrolizumab to be used in combination with trastuzumab and fluoropyrimidine- and platinum-containing chemotherapy for the first-line treatment of locally advanced unresectable or metastatic HER2-positive gastric or gastroesophageal junction adenocarcinoma. The recommended dosage for the same is 200 mg every 3 weeks or 400 mg every 6 weeks. The approval is based on the interim results of a trial involving 264 patients that saw an overall response rate of 74% and a median duration of response of 10.6 months in patients who received pembrolizumab 200 mg every 3 weeks with trastuzumab and either fluorouracil plus cisplatin or capecitabine plus oxaliplatin.

Jooae Choe et al. conducted a retrospective study to find out features on preoperative CT that could predict pathologic lymphovascular invasion (pLVI) in stage IA non-small cell lung cancer (NSCLC) and to determine the prognostic value of these features in patients who undergo sublobar resection. The study included 904 patients who underwent lobectomy or sublobar resection. It was observed that pLVI was present only in solid-dominant part solid nodules (PSNs) and solid nodules with solid portion diameter >10 mm. Among these peritumoral interstitial thickening and pleural contact were independent predictors of pLVI.

Srishti Saha et al. conducted a prospective survey-based study to determine the short-term and long-term safety of fecal microbiota transplantation (FMT) for recurrent Clostridioides difficile infection (CDI). The study involved periodic follow-up of 609 patients who underwent FMT. Although 73 new diagnoses (gastrointestinal, weight gain and new infections) were made overall, they were unrelated to FMT. Hence it was concluded that FMT is safe and effective with a low risk of transmission of infections.

Abhiram Duvvuri et al. conducted a systematic review and meta-analysis to compare incidence rates of metachronous colorectal cancer (CRC) and CRC-related mortality in patients with no adenomas, low-risk adenomas (LRAs), or high-risk adenomas (HRAs), detected at index colonoscopy. Twelve studies with 510,019 patients were analyzed and it was found that the risk of metachronous CRC and mortality is significantly higher for patients with HRAs but only low for those with LRA.

Low-intensity transcranial focused ultrasound or tFUS is a noninvasive, precise and fully reversible neuromodulation technology that shows promise in the treatment of a multitude of neurological and psychiatric diseases and conditions. It involves the transmission of pulsed mechanical energy through the skull, with high spatial resolution and selectivity, at highly targeted brain regions. Researchers have found that excitatory neurons showed high sensitivity to ultrasound pulse repetition frequency, whereas inhibitory neurons did not and this property of focused ultrasound facilitates precise targeting of brain circuits.

The aim of the proof-of-concept study conducted by Sergio Grosu et al. was to establish a noninvasive, radiomics-based machine-learning differentiation of benign and premalignant polyps in CT colonography data sets. CT colonography detected polyps were classified as benign or premalignant according to the histopathologic reference standard. A training set consisting of 107 colorectal polyps in 63 patients were used to fit the random forest model. The machine learning based image analysis allowed differentiation of benign and premalignant colorectal polyps.

Daniel G. Whitney et.al. conducted a study to determine prevalence of major noncommunicable diseases in young adults with pediatric-onset disabilities and compared it in adults without pediatric onset disabilities. The researchers found that young adults with pediatric onset disabilities showed an early onset of several noncommunicable diseases. They were contributors to global and national burden of disease and mortality.

This study investigates whether 1) Silver diamine fluoride (SDF) application using Super Floss can arrest and/or reverse initial interproximal caries on primary molars and 2) whether SDF applied with Super Floss is more effective in arresting or remineralizing initial interproximal lesion in comparison to SDF applied without Super Floss or fluoride varnish applied alone.

The purpose of this study is to compare standard occupational therapy to a combination of conventional (standard) and robotic therapy. The Reo Go device will provide robotic therapy that gives therapists a tool that could make stroke treatment faster and better by helping patients practice more accurate arm movements with help from the device.

Georgios Tsakonas et.al. conducted a study to understand the alterations in gene expression in brain metastasis versus primary tumour as it may increase aggressiveness and impair therapeutic efforts. The researchers concluded  identified a unique gene downregulation pattern in brain metastases compared with primary tumours. This finding may explain the lower intracranial efficacy of systemic therapy, especially immunotherapy, in brain metastasis of patients with non–small-cell lung cancer.

A 30-year-old female presented with rapid onset of acute dysarthria and left oculomotor paralysis. The MRI showed ruptured anterior midbrain cavernoma. A conservative approach was adopted as the patient was stable. However, one month later she experienced a new bleed with right hemiparesis, diplopia and severe dysarthria. The haemorrhage extended to the surface of the midbrain anteriorly and extended posteriorly without reaching the surface of the safe entry zone. The approach to a cavernous malformation via safe zones are not always feasible due to the proximity of several critical neural structures as in this case. The resection via a posterolateral route using the supracerebellar infratentorial approach was performed successfully.

As many as half of patients diagnosed with metastatic HER2-positive breast cancer will see their cancer spread to their brain. Though brain metastases, or "Brain Mets," are rare, they are exceedingly difficult to treat, so these patients experience poor outcomes. At this year’s ASCO meeting, Dr. Nancy Lin of Dana-Farber Cancer Institute presented promising results from the HER2CLIMB trial for these patients. In this video BCRF talks with Dr. Lin about her research focus, Brain Mets, and HER2CLIMB’s findings.

Case Studies

May 14, 2021

Dominik Reinert et al. report the case of a 61-year-old male who presented with paraparesis due to bilateral subdural bleeding as seen in cranial CT. His blood work revealed elevated CRP and leukocytosis and a chest X-ray demonstrated pleural effusion with pulmonary consolidation in the left lower lobe of the lung. Despite the administration of antibiotics, his flu-like symptoms and increase in the inflammatory parameters persisted. His SARS-CoV2-RNA and SARS-CoV2 E-gene tests were negative. However, consolidation and patchy ground glass opacity in the left lower lobe of the lung and hyperdensity in the left pulmonary artery of the left upper and lower lobe indicating pulmonary embolism were seen in the CT.

Ekmektzoglou K. et al report the case of a 79-year-old male who underwent a programmed ERCP session for a mid-CBD stricture. The patient’s vital signs and hemodynamic parameters were stable during the procedure. After the procedure,  he developed marked desaturation and hypotension while repositioning the patient from the left lateral decubitus to the supine position. A bedside transesophageal echocardiogram bubble study revealed a patent foramen ovale and head computed tomography demonstrated an extensive ischemic infarction.

Four years after the diagnosis she presented with decreased consciousness and fever. Investigations demonstrated elevated levels of WBCs, CRP, ACTH and HbA1c. Her fever subsided with antibiotics but subsequently, erythematous vesicles appeared on her chest and she was diagnosed with herpes zoster.
