Such psychosis (when diagnosed as such), is often considered "premenstrual exacerbation" or "menstrual psychosis", or postpartum psychosis. Childbirth may trigger the disorder in some women. Approximately 1 in 10,000 women experience brief psychotic disorder shortly after childbirth. Diagnosis
The symptoms must not be caused by schizophrenia, schizoaffective disorder, delusional disorder, or mania in bipolar disorder. They must also not be caused by a drug (such as amphetamines) or medical condition (such as a brain tumor). Differential diagnosis
There are general medical causes of brief psychosis that should be considered during evaluation, including postnatal depression, HIV and AIDS, malaria, syphilis, Alzheimers disease, Parkinsons disease, hypoglycaemia (an abnormally low level of glucose in the blood), lupus, multiple sclerosis, brain tumor, SARS-CoV-2 (COVID-19) infection and pediatric autoimmune neuropsychiatric disorders (PANS). Epidemiology
The exact incidence and prevalence of brief psychotic disorder is not known, but it is generally considered uncommon. Internationally, it occurs twice as often in women than men, and even more often in women in the United States. It typically occurs in the late 30s and early 40s. Approximately 1 in 10,000 women experience brief psychotic disorder shortly after childbirth. History
Otto Fenichel noted how such short psychotic breaks were more common in World War II than in World War I, in the wake of traumatic shocks: he considered in such cases that "enough preconscious attention remains to re-establish the contact with reality as soon as it becomes bearable again". BPD in Film/TV/Media
BPD and its symptoms were featured in the Kevin Spacey and Daniel Wu-starring film Inseparable.
S. mansoni was first noted by Theodor Maximillian Bilharz in Egypt in 1851, while discovering S. haematobium. Sir Patrick Manson identified it as unique species in 1902. Louis Westenra Sambon gave the name Schistosomum mansoni in 1907 in honour of Manson. Structure
Adult
Schistosomes, unlike other trematodes, are long and cylindrical worms and are sexually dimorphic. The male S. mansoni is approximately 1 cm long (0.6–1.1 cm) and is 0.1 cm wide. It is white, and it has a funnel-shaped oral sucker at its anterior end followed by a second pediculated ventral sucker. The external part of the worm is composed of a double bilayer, which is continuously renewed as the outer layer, known as the membranocalyx, and is shed continuously. The tegument bears a large number of small tubercules. The suckers have small thorns in their inner part as well as in the buttons around them. The male genital apparatus is composed of 6 to 9 testicular masses, situated dorsally. There is one deferent canal beginning at each testicle, which is connected to a single deferent that dilates into a reservatory, the seminal vesicle, located at the beginning of the gynaecophoric canal. The copula happens through the coaptation of the male and female genital orifices.The female has a cylindrical body, longer and thinner than the males (1.2 to 1.6 cm long by 0.016 cm wide). It has the general appearance of a roundworm. The female parasite is darker, and it looks gray.
