Bloody tears (Haemolacria) are a rare symptom that can be caused by local or systemic pathology. It is one of the most alarming symptom in ophthalmology. Besides those, idiopathic cases have been reported. A case of hyperthyroidism where haemolacria was secondary to the condition has also been reported. Haemolacria are also reported as secondary to epistaxis. Psychogenic causes are described including Munchausen Syndrome by proxy. Here we describe a series of four cases of haemolacria along with bleeding from other sites, found as associated features of dissociative disorders. In this series, patients with age ranging from 14-17 years, three of them are female and one male have been included. Examination excluded local ocular and nasal pathology, coagulopathy and hyperthyroidism. In course of their illness, two of these cases met the DSM 5 criteria for both dissociative disorders and conversion disorders, rest of them have been diagnosed as mixed dissociative disorders. After appropriate intervention, three patients recovered completely and in one patient symptoms (also bleeding) recurred on re-exposure to the previous stress factors.We report three cases of Dissociative disorders and one with both dissociative and conversion disorder where bloody tears were one of the feature. To the best of our knowledge this is the first official report of its kind in Bangladesh. (J Bangladesh Coll

The method of fault diagnosis based on dissolved gas analysis (DGA) is of great importance to detect possible failures in the transformer and to improve the safety of the electrical system. The DGA data of the transformer in the smart grid has the characteristics of a large amount, different types and a low density of values. Since the power transformer is an important type of power supply in the electrical network, this document provides a complete overview of the power transformer and describes how to diagnose faults. Furthermore, on-line monitoring, the method of fault diagnosis and condition-based maintenance strategy decision-making method as also have been described. The paper presents detailed literature on the recent advancements and methods being adopted by various authors on fault detection.
