Marijuana smokers more likely to suffer emphysema than cigarette smokers

Time : 29th of November 2022 09:51:52 AM Radiology,Pulmonology,Physician/Medicine

About 75% of marijuana smokers suffered emphysema, a lung disease causing difficulty breathing, compared to 67% of tobacco smokers in a study. In comparison, only 5% of non-smokers suffered emphysema. Also, gynecomastia was more common in marijuana smokers (38% vs 11%). However, there were no differences in the rates of coronary artery calcification between the groups.

Why do people with autism have less eye contact?

Time : 11th of November 2022 12:35:29 PM Radiology,Psychiatry & Mental Health,Neurology & Neurosurgery

People with autism spectrum disorder had remarkably lower activity in the brain region known as the dorsal parietal cortex than people who do not have ASD, as per a study. The neural activity in this region was synchronous among typical people during eye-to-eye contact, but it was not synchronous in people with ASD, which is consistent with their social interactions.

Researchers uncover brain activity linked to dissociative symptoms

Time : 11th of November 2022 10:09:20 AM Radiology,Neurology & Neurosurgery

The functional MRI studies on women with and without a history of trauma, PTSD or certain levels of dissociative symptoms revealed that different dissociative symptoms were linked to connections of brain areas behind emotion and cognition processes. Dissociation due to PTSD and dissociation central to dissociative identity disorder also had unique brain signatures.

Cardiac CT after stroke could help identify cardioembolism

Time : 17th of October 2022 09:43:50 AM Radiology,Physician/Medicine,Neurology & Neurosurgery,Diagnostics & Pathology,Cardiology

Cardiac CT during initial ischemic stroke imaging protocol was superior to conventional transthoracic echocardiography in detecting high-risk sources of embolism, as per a study. Cardiac CT detected the cardioaortic embolism sources in 11.4% of patients compared to 4.9% with TTE. These findings suggest adding cardiac CT to stroke imaging protocol could be beneficial.

An ultrasound can move kidney stones in awake patients

Time : 11th of October 2022 01:09:50 PM Radiology,Physician/Medicine,Nephrology,Emergency Medicine

The new technique uses a handheld transducer that directs ultrasound waves towards the stones to move or pass them or even break them using burst wave lithotripsy, as per a report. Unlike the standard shock wave lithotripsy procedure, this technique does not need sedation and can be performed in an emergency room setting. Also, this procedure is nearly painless.

Research suggests new thresholds for risk stratification in NASH

Time : 4th of October 2022 01:55:22 PM Radiology,Gastroenterology

Investigators suggested that 16.6 kPa is the best liver stiffness threshold on vibration-controlled transient elastography to predict disease development from bridging fibrosis to cirrhosis. Also, 30.7 kPa predicted liver-related events like ascites, portal hypertension-linked gastrointestinal bleeding, hepatic encephalopathy, liver transplantation and death.

A case of breast cancer remission possibly due to magic mushrooms and cannabis

Time : 29th of September 2022 11:50:08 AM Radiology,Psychiatry & Mental Health,Physician/Medicine,Oncology,Nursing

A 49-year-old woman diagnosed with stage IV breast cancer in 2018 received chemotherapy and self-administered psilocybin and cannabis oil. Her tumors vanished in January 2019, but she continued taking them to avoid tumour recurrence. Her cancer returned in June 2020. She began chemotherapy and taking psilocybin and cannabis oil. Her tumours stabilized by October 2021.

Guidance for the use of cardiac CT in cancer patients

Time : 22nd of September 2022 02:56:01 PM Radiology,Oncology,Cardiology

SCCT's expert consensus statement includes advice from experts in radiology, cardiology, imaging, cardio-oncology, radiation-oncology, and CV imaging. The guidance stresses a baseline screening for underlying ASCVD risk factors in cancer survivors and patients. Patients with CAC on previous chest CT scans without ASCVD should be risk-stratified to lower the risk.

New technique may help detect early cancer signs in dense breasts

Time : 16th of September 2022 02:09:00 PM Radiology,Oncology

It was initially developed to image breast density in mice. It uses a computer program that allows sorting breast tissue for imaging using one of two techniques. It uses an imaging technique that is used to identify changes in the blood vessels of the retina. It is easy to use and available for free. Translating the approach from mice to humans could help detect breast cancer.

A case of relative afferent pupillary defect in a paediatric patient

Time : 6th of September 2022 11:30:06 AM Trending,Radiology,Physician/Medicine,Paediatrics,Nursing,Neurology & Neurosurgery,Diagnostics & Pathology

A 13-year-old girl presented to a hospital with blurry vision and painful eye movements in the left eye. The patient developed weakness and paresthesias in her left leg before 3 weeks. MRI of the brain and spine showed many hyperintense lesions on T2 weighted images. Based on the clinical and lab findings, she was diagnosed with multiple sclerosis with retrobulbar neuritis.
