Childhood masturbations (CM) is stimulation of genital by pre-adolescent children with accompanying symptoms including sweating, tachycardia, blushing, muscle contraction and increase rate of breathing. We are presenting case series of three patient, who presented with history of vague symptoms and ultimately diagnosed and managed as case of CM. A 2 years old girl presented with history of to and fro movements. A 3 years old girl presented with history of rubbing of inner thighs and 3 years old boy presented with history of holding and rubbing genitalia with forward bending and symptoms of increase breathing, flushing and sweating. Video recording was available with two patients, which helped in making final diagnosis. Parents were counselled and patients referred for behavioural therapy.
Conclusion: In young child CM should be considered in differential diagnosis whenever history is not fully suggestive of seizures.
Background: The cancer of colon is one of the important cause of morbidity and mortality in adults. For the management of colonic carcinoma, the definitive diagnosis depends on the histological examination of biopsy specimens. With the development of whole slide imaging, the convolutional neural networks are being applied to diagnose colonic carcinoma by digital image analysis.
Aim: The main aim of the current study is to assess the application of deep learning for the histopathological diagnosis of colonic adenocarcinoma by analysing the digitized pathology images.
Materials & Methods: The images of colonic adenocarcinoma and non neoplastic colonic tissue have been acquired from the two datasets. The first dataset contains ten thousand images which were used to train and validate the convolutional neural network (CNN) architecture. From the second dataset (Colorectal Adenocarcinoma Gland (CRAG) Dataset) 40% of the images were used as a train set while 60% of the images were used as test dataset. Two histopathologists also evaluated these images. In this study, three variants of CNN (ResNet-18, ResNet-34 and ResNet-50 ) have been employed to evaluate the images.
Results: In the present study, three CNN architectures(ResNet-18, ResNet-30, and ResNet-50) were applied for the classification of digitized images of colonic tissue. The accuracy (93.91%) of ResNet-50 was the highest which is followed by ResNet-30 and ResNet-18 with the accuracy of 93.04% each.
Conclusion: Based on the findings of the present study and analysis of previously reported series, the development of computer aided technology to evaluate the surgical specimens for the diagnosis of malignant tumors could provide a significant assistance to pathologists.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
