These include breast tenderness or swelling, joint pain, muscle pain, gaining weight, or feeling bloated.Because of the broad variety in clinical presentation, the onset of symptoms only during or around the luteal phase is key for diagnosing someone with PMDD rather than any other mood disorders. PMDD follows a predictable, cyclic pattern. Symptoms begin in the late luteal phase of the menstrual cycle (after ovulation) and end or are markedly reduced shortly after menstruation begins. On average, the symptoms last six days but can start up to two weeks before menses, meaning symptoms can be felt for up to three weeks out of a cycle. Severe symptoms can begin and worsen until the onset of menstruation, with many not feeling relief until a few days after menstruation ends. The most intense symptoms occurring in the week and days leading up to the first day of menstrual blood flow. The symptoms usually cease shortly after the start of the menstrual period or a few days after it ends. Various symptom and severity tracking questionnaires exist to document presence and severity of symptoms throughout consecutive menstrual cycles.The International Society for the Study of Premenstrual Disorders (ISPMD) defines two categories of premenstrual disorders: core PMD and variant PMD. Core PMD has six characteristics, all mainly focusing on the cyclical nature of PMDD and its typical onset pre-menses tracked over the course of more than two menstrual cycles.
A chylothorax is an abnormal accumulation of chyle, a type of lipid-rich lymph, in the space surrounding the lung. The lymphatics of the digestive system normally returns lipids absorbed from the small bowel via the thoracic duct, which ascends behind the esophagus to drain into the left brachiocephalic vein. If normal thoracic duct drainage is disrupted, either due to obstruction or rupture, chyle can leak and accumulate within the negative-pressured pleural space. In people on a normal diet, this fluid collection can sometimes be identified by its turbid, milky white appearance, since chyle contains emulsified triglycerides. Chylothorax is a rare but serious condition, as it signals leakage of the thoracic duct or one of its tributaries. There are many treatments, both surgical and conservative. About 2–3% of all fluid collections surrounding the lungs (pleural effusions) are chylothoraces. It is important to distinguish a chylothorax from a pseudochylothorax (a pleural effusion that happens to be high in cholesterol), which has a similar appearance visually but is caused by more chronic inflammatory processes and requires a different treatment. Signs and symptoms
The symptoms of a chylothorax depend its size and the underlying cause. A small chylothorax may not cause any symptoms and only be detected on a chest X-ray performed for another reason.
