Trichotillomania is a common form of obsessive and compulsive behavioural disorder which results in traumatic hair loss because of recurrent pulling of one's own hair, preceded by increase in sense of tension before pulling out the hair, followed by sense of relief after pulling out the hair. We present a case series of 09 patients with clinical, dermoscopic and/ or histopathologically conrmed cases of Trichotillomania in a tertiary care centre in Western India with female to male ratio 2:1 and mean age 30.78. All patients presented with alopecic patches on the scalp with dermoscopic ndings of broken hair shafts of variable lengths, ame hair, coiled hair and tulip hair (polarized light using Dermlite DL4 , USA 10X polarized). The most common histopathological nding was increased number of hair follicle and pigmented cast. The patients were treated with combination of psychotropic medications and psychological intervention. Out of 9 patients 03 patients had recurrent disease and poor response to the treatment over a period of more than one year of follow up.
Placebo effect is considered as an effect which improves patient's health because of his belief in the treatment or drug but has no medical effects. This is mostly related with psychology of the patient and results in improvement of health even on using non clinical treatment. On the other hand, nocebo effect deteriorates the health of the patient due to the negative belief system. In this review paper, we have considered different theories and how placebo effect is beneficial in treatment of various health conditions arising due to psychological factors. Placebo effect has proved to be useful in curing depression, pain, insomnia, fatigue and most recently it has shown positive results in treatment of Corona patients too.
In recent few decades interest has been developed and research has been carried out to study aggressive behaviour. It is known that neurotransmitters control aggression but the mechanisms involved are still not clear. The current pandemic led to many psychological issues. In this study, we did a small online survey and used online reports (newspapers, digital publications) to analyze the psychology of the person because of novel COVID-19 lockdown in India and many psychological health issues experienced by society. This study focuses on aggressive behavior of the person, chemistry & factors related to neurotransmitters with respect to serotonin. Studies suggest that people with low serotonin concentration are aggressive in nature)
