ABSTRACT Herein, we report the case of a 56-year-old male patient with acute myeloid leukemia (AML) in remission who had asymptomatic myocardial ischemia on myocardial perfusion imaging and transthoracic echocardiography. Angiography did not reveal any significant coronary artery disease. Although the etiology is not entirely clear, this case suggested that myocardial perfusion imaging should be considered in patients with AML who received idarubicin to screen for possible myocardial dysfunction.

The Role of Histogram-Based Textural Analysis of 18F-FDG PET/CT in Evaluating Tumor Heterogeneity and Predicting the Prognosis of Invasive Lung Adenocarcinoma

xlomafota13 shared this article with you from Inoreader The Role of Histogram-Based Textural Analysis of <sup>18</sup>F-FDG PET/CT in Evaluating Tumor Heterogeneity and Predicting the Prognosis of Invasive Lung Adenocarcinoma Via Mol Imaging Radionucl Ther Mol Imaging Radionucl Ther. 2022 Feb 2;31(1):33-41. doi: 10.4274/mirt.galenos.2021.79037. ABSTRACT OBJECTIVES: This study aimed to investigate the contributory role of histogram-based textural features (HBTFs) extracted from 18fluorinefluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) in tumoral heterogeneity (TH) evaluation and invasive lung adenocarcinoma (ILA) prognosis prediction. METHODS: This retrospective study analyzed the data of 72 patients with ILA who underwent 18F-FDG PET/CT followed by surgical resection. The maximum standardized uptake value (SUVmax), metabolic tumor volume, and total lesion glycolysis values were calculated for each tumor. Additionally, HBTFs were extracted from 18F-FDG PET/CT images using the software program. ILA was classified into the following five histopathological subtypes according to the predominant pattern: Lepidic adenocarcinoma (LA), acinar adenocarcinoma, papillary adenocarcinoma, solid adenocarcinoma (SA), and micropapillary adenocarcinoma (MA). Differences between 18F-FDG PET/CT parameters and histopathological subtypes were evaluated using non-parametric tests. The study endpoints include overall survival (OS) and progression-free survival (PFS). The prognostic values of clinicopathological factors and 18F-FDG PET/CT parameters were evaluated using the Cox regression analyses. RESULTS: The median SUVmax and entropy values were significantly higher in SA-MA, whereas lower in LA. The median energy-uniformity value of the LA was significantly higher than the others. Among all parameters, only skewness and kurtosis were significantly associated with lymph node involvement status. The median values for follow-up time, PFS, and OS were 31.26, 16.07, and 20.87 months, respectively. The univariate Cox regression analysis showed that lymph node involvement was the only significant predictor for PFS. The multivariate Cox regression analysis revealed that higher SUVmax (≥11.69) and advanced stage (IIB-IIIA) were significantly associated with poorer OS [hazard ratio (HR): 3.580, p=0.024 and HR: 7.608, p=0.007, respectively]. CONCLUSION: HBTFs were tightly associated with clinicopathological factors causing TH. Among the 18F-FDG PET/CT parameters, only skewness and kurtosis were associated with lymph node involvement, whereas SUVmax was the only independent predictor of OS. TH measurement with HBTFs may contribute to conventional metabolic parameters in guiding precision medicine for ILA. PMID:35114750 | DOI:10.4274/mirt.galenos.2021.79037 View on the web Inoreader.

Oculo-auriculo-vertebral spectrum: new genes and literature review on a complex disease

xlomafota13 shared this article with you from Inoreader Oculo-auriculo-vertebral spectrum: new genes and literature review on a complex disease Via oto-rhino-laryngologie J Med Genet. 2022 Feb 2:jmedgenet-2021-108219. doi: 10.1136/jmedgenet-2021-108219. Online ahead of print. ABSTRACT Oculo-auriculo-vertebral spectrum (OAVS) or Goldenhar syndrome is due to an abnormal development of first and second branchial arches derivatives during embryogenesis and is characterised by hemifacial microsomia associated with auricular, ocular and vertebral malformations. The clinical and genetic heterogeneity of this spectrum with incomplete penetrance and variable expressivity, render its molecular diagnosis difficult. Only a few recurrent CNVs and genes have been identified as causatives in this complex disorder so far. Prenatal environmental causal factors have also been hypothesised. However, most of the patients remain without aetiology. In this review, we aim at updating clinical diagnostic criteria and describing genetic and non-genetic aetiologies, animal models as well as novel diagnostic tools and surgical managemen t, in order to help and improve clinical care and genetic counselling of these patients and their families.

Prognostic scores in laryngeal cancer

xlomafota13 shared this article with you from Inoreader Prognostic scores in laryngeal cancer Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Feb 2. doi: 10.1007/s00405-021-07233-2. Online ahead of print. ABSTRACT PURPOSE: To evaluate the utility of various pre-treatment prognostic scoring systems for overall survival (OS) in laryngeal cancer, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), modified Glasgow Prognostic Score (mGPS) and systemic immune-inflammatory index (SIII). METHODS: We undertook a retrospective 5-year study of 220 patients with laryngeal squamous cell carcinoma undergoing active treatment. RESULTS: On multivariate analysis, low NLR (≤ 2.415, p = 0.001, OR 3.851), low PLR (≤ 269.855, p = 0.002, OR 5.520), high LMR (> 2.225, p < 0.001, OR 0.458) and low SIII (≤ 1144.465, p = 0.003, OR 3.673) were significantly associated with improved OS, accounting for confounding factors of tumour subsite, T-stage and performance status. C-reacti ve protein (CRP) alone (p = 0.264) and mGPS (p = 0.350) were not significantly associated with OS. CONCLUSIONS: NLR, PLR, LMR and SIII represent inexpensive, easily obtainable adjuvant decision-making tools which could help tailor individualised treatment regimes. Further investigation into the utility of combination scores and the role of different laryngeal subsites may be of interest. PMID:35112153 | DOI:10.1007/s00405-021-07233-2 View on the web Inoreader.

Association Between Clinical Symptoms, Electrodiagnostic Findings, Clinical Outcome, and Prodromal Symptoms in Patients With Bell's Palsy

xlomafota13 shared this article with you from Inoreader Association Between Clinical Symptoms, Electrodiagnostic Findings, Clinical Outcome, and Prodromal Symptoms in Patients With Bell's Palsy Via otol rhinol Ann Otol Rhinol Laryngol. 2022 Feb 3:34894221075107. doi: 10.1177/00034894221075107. Online ahead of print. ABSTRACT OBJECTIVE: This study aimed to determine which prodromal symptoms frequently occur in patients with Bell's palsy and evaluate the association between these symptoms and clinical severity of paresis or the severity of facial nerve injury. MATERIALS AND METHODS: The study included 86 patients with Bell's palsy between August 2018 and April 2020. Severity l evels of Bell's palsy and facial nerve damage were evaluated using the House-Brackmann (H-B) grading scale and electrodiagnostic study, respectively. Subsequently, a self-reported questionnaire on prodromal symptoms was administered. To assess the degree of recovery, the H-B grade was reported at 9 weeks and 6 months after the onset of paralysis. RESULTS: The most common prodromal symptoms were postauricular pain, sensory decline in the tongue, headache on the affected side, myalgia, facial sensory decline on the affected side, taste impairment, and dry eye. Taste impairment was significantly correlated with severe facial paralysis reported at 9 weeks after onset (P < .05) and was not related to the severity of paresis assessed at initial examination or 6 months after onset or on electrodiagnostic findings. CONCLUSIONS: The prodromal symptoms of Bell's palsy were not associated with the severity of facial nerve injury in an electrodiagnostic study. Taste impair ment was related to clinical severity of paralysis at subacute stage, 9 weeks after onset, but it was not associated with long-term prognosis.
