Rapid and accurate diagnosis of various lung changes caused by SARS-Co V-2 is extremely important and relevant, as it will allow timely action to take the necessary measures to treat and stop the spread of lesions. Ultrasound diagnosis allows you to quickly, non-invasively, and cheaply conduct research that is accurate and effective enough to make or confirm a diagnosis. The article highlights the main structural changes in the lungs found in 86 patients with a positive PCR test for coronavirus virus. The following sonographic signs were observed during the study: B-line (in 54% of patients), white lung effect (in 20.6% of patients), consolidation (11 people – 17.5%), of which 6 patients with consolidation less than 1 cm and 5 patients had consolidations greater than 1 cm, pleural effusion was observed in 7 patients. Our research is important both in terms of increasing the informativeness of the diagnosis for physicians and patients, for whom it is important to quickly, non-invasively, and economically compare, detect disease and begin treatment promptly.

Pleural effusion is a condition characterized by the accumulation of excessive pleural fluid in pleural cavity as a result of transudation and exudation. The most commonly reported cause of exudative pleural effusion is Mycobaterium tuberculosis. This study was aimed to identify Mycobacterium tuberculosis in pleural fluid through PCR test and to examine the relationship between PCR test and MGG staining of pleural fluid in patients with suspected tuberculous pleural effusion, which was performed in Clinical Pathological Laboratory Installation of dr. Wahidin Sudirohusodo hospital in Makassar and Faculty Research Unit Laboratory in Hasanuddin University from March to November 2012. This study was a cross sectional study. Subjects in this study consisted of 75 patients (41 males and 34 females[AA1] ) with average age of 40-49 years (30.7%). Pleural effusion patients with suspected tuberculosis who had a positive PCR result was 58.7%, negative PCR result was 41.3% and positive rivalta result in 82.7%, negative rivalta result in 17.3%. Statistical analysis using independent T-test indicated a non-significant relationship between PCR test and average MN and PMN cell percentage in MGG staining (P > 0.005). This study concluded that in MGG staining, average MN cell percentage was higher in PCR TB (+) group compared to PCR  (-) group, but the difference was not significant.

ABSTRACTBackgroundThe lung CT images of COVID-19 patients can be characterized by three different regions – Ground Glass Opacity (GGO), consolidation and pleural effusion. GCOs have been shown to precede consolidations. Quantitative characterization of these regions using radiomics can facilitate accurate diagnosis, disease progression and response to treatment. However, according to the knowledge of the author, regional CT radiomics analysis of COVID-19 patients has not been carried out. This study aims to address these by determining the radiomics features that can characterize each of the regions separately and can distinguish the regions from each other.Methods44 radiomics features were generated with four quantization levels for 23 CT slice of 17 patients. Two approaches were the implemented to determine the features that can differentiate between lung regions – 1) Z-score and correlation heatmaps and 2) one way ANOVA for finding statistically significantly difference (p<0.05) between the regions. Radiomics features that show agreement for all cases (Z-score, correlation and statistical significant test) were selected as suitable features. The features were then tested on 52 CT images.Results10 radiomics features were found to be the most suitable among 44 features. When applied on the test images, they can differentiate between GCO, consolidation and pleural effusion successfully and the difference provided by these 10 features between three lung regions are statistically significant.ConclusionThe ten robust radiomics features can be useful in extracting quantitative data from CT lung images to characterize the disease in the patient, which in turn can help in more accurate diagnosis, staging the severity of the disease and allow the clinician to plan for more successful personalized treatment for COVID-19 patients. They can also be used for monitoring the progression of COVID-19 and response to therapy for clinical trials.

Ultrasound Features

Fetal neck masses are rare and may not be apparent during the second trimester fetal anomaly screening scan. It is essential to distinguish the different pathologies as it influences prenatal counseling, antenatal, and postnatal management. Furthermore, some causes may be amenable to in utero treatment. Others have a poor prognosis due to their association with congenital syndromes and aneuploidies. Differentiating the various neck masses and reaching an accurate diagnosis are a challenge. This requires a systematic approach, time and patience, together with an experienced sonographer. Ancillary investigations like karyotyping and magnetic resonance imaging may be used as well. It is important to attain an accurate diagnosis and to follow up the fetus with serial scans as this affects antenatal counselling and prognosis as well as the mode of delivery. Here, we present four cases of fetal neck masses that were seen at our antenatal diagnostic centre and highlight the distinguishing ultrasound features of each. This will enable one to approach the ultrasound diagnosis of fetal neck masses in a methodical and logical manner.
