Conformal coverage of liver tumors by the thermal coagulation zone in 2450-MHz microwave ablation.

Conclusion: The proposed method can be applied to computer-assisted MWA treatment planning of liver tumors, and is expected to guide clinical procedures in future. PMID: 31172824 [PubMed - in process]

AbstractA 39-year-old woman experienced dyspnea and progressive dysphagia for 1  year. Dysphagia appeared for solid foods at the beginning but advanced for liquids. She described 17 kg weight loss in the past 6 months and her current weight was 38 kg [body mass index (BMI) 16 kg/m2]. Dyspnea presented with effort and lying was included after 1  month. There was no disease or surgery except chronic hepatitis C in her medical history. Physical examination revealed hyponasal speech and a mass beside the tongue base. A smoothly surfaced 4 × 3-cm vascular mass in oropharynx was dete...

Abstract OBJECTIVE: We prospectively validated stereo-electroencephalography (EEG) electrical stimulation mapping (ESM) of language against a reference standard of meta-analytic functional magnetic resonance imaging (fMRI) framework (Neurosynth). METHODS: Language ESM was performed using 50 Hz, biphasic, bipolar, stimulation at 1-8 mA, with a picture naming task. Electrode contacts (ECs) were scored as ESM+ if ESM interfered with speech/language function. For each patient, presurgical MRI was transformed to a standard space and coregistered with computed tomographic (CT) scan to obtain EC locations. After...

AbstractPurposeTo identify a potential morphological marker of remodeling and electrophysiological dysfunction, we investigated if low wall thickness is associated with low-voltage areas (LVAs) in the left atrium.MethodsWall thickness was measured by computed tomography and LVA (% area with bipolar voltage  10% of segment surface area) was observed in 123 of 215 segments (57%). Segments in the low tertile of wall thickness (

ConclusionSG leaks can add long-term morbidity. Stent can be used successfully to treat SG leak if used judiciously. There should be low threshold for investigating patients with EWL of>  100% for anatomical complications like stricture, fistula or kink in the gastric sleeve. We wanted to make the bariatric fraternity aware of a rare late (>  12 weeks) complication of gastro-colic fistula after successfully treated SG leak. Limited literature is published about this rare complication and its management which ranges from conservative management to stent placement to surgical intervention (Asian Jour...

AbstractSurgical clipping of an internal carotid artery (ICA) –posterior communicating artery (ICPC) aneurysm is often difficult in cases involving limited space to insert a clip at the proximal aneurysm neck hidden by the tent. In such cases, we perform incision of the anterior petroclinoidal fold to secure the proximal space for clip insertion. Between Apr il 2013 and March 2018, we treated 89 ICPC aneurysm cases by clipping. Incision of the anterior petroclinoidal fold was performed in 15 of the 89 cases (16.8%). Fast imaging employing steady-state acquisition (FIESTA) magnetic resonance imaging (MRI) can indicate...

ConclusionThe video demonstrates the feasibility of simultaneous laparoscopic and cystoscopic approach for excision of a bladder endometriotic nodule. Marking the nodule by simultaneous cystoscopy and laparoscopy before excision helps in removing the disease completely and avoiding unnecessary normal bladder wall excision, thus reducing the risk of recurrence and resultant small bladder symptoms.

Could the advancement of machine and deep learning algorithms be harnessed meaningfully in the area of mental health? Could depression, bipolar disorder, schizophrenia, or any other mental disorder be quantified so that technology could somehow add positively to their diagnostics or treatment? We tried to explore the uses of artificial intelligence in mental health care, and stumbled upon smart algorithms that support clinicians with early detection and diagnostics of mental health issues, with the flagging of suicide risks, and other ones that help patients manage their condition through counselling and constantly being t...

Conclusion Taken together, evidence from animal and human studies demonstrates that the brain detects levels of circulating nutrients and hormones and consequently organizes an outward response that contributes to the regulation of whole-body glucose homeostasis. However, there are major knowledge gaps about the exact nature of this response and its relative importance compared to peripheral processes. As we have seen, animal studies have provided an anatomical map of CNS glucose regulation and have identified important neurons and neural circuits involved. Additionally, the CNS sensing of key nutrients and hormones has b...
