In 1898, a detailed psychiatric case history was published about a 13-year-old that met Jean-Pierre Falret and Jules Baillargers criteria for folie circulaire, which is congruent to the modern conception of bipolar I disorder.In Emil Kraepelins descriptions of bipolar disorder in the 1920s, which he called "manic depressive insanity", he noted the rare possibility that it could occur in children. In addition to Kraepelin, Adolf Meyer, Karl Abraham, and Melanie Klein were some of the first to document bipolar disorder symptoms in children in the first half of the 20th century. It was not mentioned much in English literature until the 1970s when interest in researching the subject increased. It became more accepted as a diagnosis in children in the 1980s after the DSM-III (1980) specified that the same criteria for diagnosing bipolar disorder in adults could also be applied to children.Recognition came twenty years after, with epidemiological studies showing that approximately 20% of adults with bipolar disorder already had symptoms in childhood or adolescence. Nevertheless, onset before age 10 was thought to be rare, below 0.5% of the cases. During the second half of the century misdiagnosis with schizophrenia was not rare in the non-adult population due to common co-occurrence of psychosis and mania, this issue diminishing with an increased following of the DSM criteria in the last part of the 20th century.

The follicular cyst of the ovary is a type of functional simple cyst, and is the most common type of ovarian cyst. Signs and symptoms
Its rupture can create sharp, severe pain on the side of the ovary on which the cyst appears. This sharp pain (sometimes called mittelschmerz) occurs in the middle of the menstrual cycle, during ovulation. About a fourth of women with this type of cyst experience pain.Usually, these cysts produce no symptoms and disappear by themselves within a few months. Pathophysiology
This type can form when ovulation doesnt occur, and a follicle doesnt rupture or release its egg but instead grows until it becomes a cyst, or when a mature follicle involutes (collapses on itself). It usually forms during ovulation, and can grow to about 7 cm in diameter. It is thin-walled, lined by one or more layers of granulosa cell, and filled with clear fluid. Diagnosis
Ultrasound is the primary tool used to document the follicular cyst. A doctor monitors these to make sure they disappear, and looks at treatment options if they do not. References
