Fallopian tube tumor

Blepharospasm refers to involuntary spastic contractions of the orbicularis oculi muscles of the eyelids and periorbital area, manifesting as frequent blinking or progressively worsening difficulty opening the eyes in one or both eyes. According to the etiology, it can be divided into primary blepharospasm and secondary blepharospasm.

View detailsChalazion
A chalazion, also known as a meibomian cyst or meibomian gland lipogranuloma, is an idiopathic chronic non-suppurative inflammation of the meibomian gland. The meibomian glands in the eyelids secrete oil to keep the eyes moist, but when their ducts become blocked, it can lead to the formation of a cyst, known as a chalazion. A chalazion presents as a red, swollen lump on the eyelid, and the cyst can range in size from a grain of rice to a soybean.
Constipation
Constipation is a condition characterized by reduced frequency of bowel movements, decreased stool volume, hard stools, and straining during defecation. It can occur in various acute and chronic diseases. Constipation can be classified based on the presence of organic lesions: Organic constipation: Refers to constipation caused by intestinal diseases such as rectal or anal lesions, extra-intestinal diseases such as those affecting the neuropsychiatric or endocrine systems, or the use of certain constipation-inducing medications. Functional constipation: There are no organic lesions in the organs. It refers to constipation mainly caused by poor lifestyle habits, such as defecation habits, dietary habits, and mental stress. Based on different pathophysiological mechanisms, it can be classified as: Defecatory disorders: Refers to the accumulation of stool in the rectum due to pelvic floor dysfunction or discoordinated pelvic floor muscle movement, preventing its smooth expulsion from the anus. Slow-transit constipation: Refers to the slower-than-normal movement of intestinal contents from the proximal colon to the distal colon and rectum. Mixed constipation: Possesses the causes and characteristics of both of the above types.
View detailsEndocrine disorders
The endocrine system is a humorally regulated system composed of endocrine glands, endocrine tissues, and endocrine cells. It primarily regulates hormone secretion under the control of the nervous system and feedback from material metabolism, thereby regulating various human activities and maintaining human health. Endocrine imbalance, literally, can be understood as an abnormality in the function of the human endocrine system. It is not a disease but a general concept, referring to a series of symptoms caused by abnormal hormone action due to various endocrine diseases. The peak age for endocrine system diseases is concentrated in young and middle-aged adults, with a trend towards younger onset. The incidence in women is significantly higher than in men.

A bursa is a small, fluid-filled sac, and there are over 150 of them in the human body. They are located between bones, tendons, joints, and muscles, acting as cushions to prevent friction between these structures. Bursitis is the inflammation of a bursa due caused by friction, traumatic injury, or bacterial infection. It is primarily characterized by localized swelling, pain, and restricted movement.
View detailsNocturnal enuresis in children
Infants urinate approximately 20 times a day during their first year. As they grow older, bladder capacity increases, and by age 3, they urinate about 11 times a day, with 0-1 nocturnal urinations, which are voluntary. If urination is involuntary, occurs more than twice a week, and persists for over three months, it is considered enuresis. Statistics show that approximately 16% of 5-year-olds, 10% of 7-year-olds, and 5% of 11-12-year-olds suffer from enuresis.
