Pediatric Gynecology
Pediatric gynaecology or pediatric gynecologySee American and British English spelling differences. ''Gynecology'' is the American spelling, but it is also common in international contexts, e.g. International Federation of Gynecology and Obstetrics anInternational Society of Ultrasound in Obstetrics and Gynecology is the medical practice dealing with the health of the vagina, vulva, uterus, and ovaries of infants, children, and adolescents. Its counterpart is pediatric andrology, which deals with medical issues specific to the penis and testes. Etymology The word "gynaecology" comes from the Greek γυνή ''gyne''. "woman" and ''-logia'', "study." History Examination Assessment of the external genitalia and breast development are often part of routine physical examinations. Physicians also can advise pediatric gynecology patients on anatomy and sexuality. Assessment can include an examination of the vulva, and rarely involve the introduction of instruments into the vagina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Female Reproductive System
The human female reproductive system is made up of the internal and external sex organs that function in the reproduction of new offspring. The reproductive system is immature at birth and develops at puberty to be able to release matured ova from the ovaries, facilitate their fertilization, and create a protective environment for the developing fetus during pregnancy. The female reproductive tract is made of several connected internal sex organs—the vagina, uterus, and fallopian tubes—and is prone to infections. The vagina allows for sexual intercourse and childbirth, and is connected to the uterus at the cervix. The uterus (or womb) accommodates the embryo by developing the uterine lining. The uterus also produces secretions which help the transit of sperm to the fallopian tubes, where sperm fertilize the ova. During the menstrual cycle, the ovaries release an ovum, which transits through the fallopian tube into the uterus. If an egg cell meets with sperm on its way t ...

Swyer Syndrome
XY complete gonadal dysgenesis, also known as Swyer syndrome, is a type of defect hypogonadism in a person whose karyotype is 46,XY. Though they typically have normal vulvas, the person has underdeveloped gonads, fibrous tissue termed " streak gonads", and if left untreated, will not experience puberty. The cause is a lack or inactivation of an SRY gene which is responsible for sexual differentiation. Pregnancy is sometimes possible in Swyer syndrome with assisted reproductive technology. The phenotype is usually similar to Turner syndrome (45,X0) due to a lack of X inactivation. The typical medical treatment is hormone replacement therapy. The syndrome was named after Gerald Swyer, an endocrinologist based at London's University College Hospital, who first reported two cases in 1955. Signs and symptoms Those with Swyer syndrome develop phenotypes typical of females and nonfunctional gonads. Individuals are most commonly diagnosed during adolescence after puberty fails to occu ...

Seborrhoeic Dermatitis
Seborrhoeic dermatitis (also spelled seborrheic dermatitis in American English) is a long-term skin disorder. Symptoms include flaky, scaly, greasy, and occasionally itchy and inflamed skin. Areas of the skin rich in oil-producing glands are often affected including the scalp, face, and chest. It can result in social or self-esteem problems. In babies, when the scalp is primarily involved, it is called cradle cap. Mild seborrhoeic dermatitis of the scalp may be described in lay terms as dandruff due to the dry, flaky character of the skin. However, as dandruff may refer to any dryness or scaling of the scalp, not all dandruff is seborrhoeic dermatitis. Seborrhoeic dermatitis is sometimes inaccurately referred to as seborrhoea. The cause is unclear but believed to involve a number of genetic and environmental factors. Risk factors for seborrhoeic dermatitis include poor immune function, Parkinson's disease, and alcoholic pancreatitis. The condition may worsen with stres ...

Dermatitis
Dermatitis is a term used for different types of skin inflammation, typically characterized by itchiness, redness and a rash. In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened. The area of skin involved can vary from small to covering the entire body. Dermatitis is also called eczema but the same term is often used for the most common type of skin inflammation, atopic dermatitis. The exact cause of the condition is often unclear. Cases may involve a combination of allergy and poor venous return. The type of dermatitis is generally determined by the person's history and the location of the rash. For example, irritant dermatitis often occurs on the hands of those who frequently get them wet. Allergic contact dermatitis occurs upon exposure to an allergen, causing a hypersensitivity reaction in the skin. Prevention of atopic dermatitis is typically with essential fatty acids, and may be treated with moistu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaginal Foreign Body
In mammals and other animals, the vagina (: vaginas or vaginae) is the elastic, muscular reproductive organ of the female genital tract. In humans, it extends from the vulval vestibule to the cervix (neck of the uterus). The vaginal introitus is normally partly covered by a thin layer of mucosal tissue called the hymen. The vagina allows for copulation and birth. It also channels menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle. To accommodate smoother penetration of the vagina during sexual intercourse or other sexual activity, vaginal moisture increases during sexual arousal in human females and other female mammals. This increase in moisture provides vaginal lubrication, which reduces friction. The texture of the vaginal walls creates friction for the penis during sexual intercourse and stimulates it toward ejaculation, enabling fertilization. Along with pleasure and bonding, women's sexual behavior with other people c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menarche
Menarche ( ; ) is the first menstrual cycle, or first menstruation, menstrual bleeding, in female humans. From both social and medical perspectives, it is often considered the central event of female puberty, as it signals the possibility of fertility. Girls experience menarche at different ages, but the most common age is 12. Having menarche occur between the ages of 9–14 in the West is considered normal.US National Health Statistics Report September 2020 The timing of menarche is influenced by female biology, as well as Genetics, genetic, environmental factors, and nutritional factors. The mean age of menarche has declined over the last century, but the magnitude of the decline and the factors responsible remain subjects of contention. The worldwide average age of menarche is very difficult to estimate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dysmenorrhea
Dysmenorrhea, also known as period pain, painful periods or menstrual cramps, is pain during menstruation. Its usual onset occurs around the time that menstruation begins. Symptoms typically last less than three days. The pain is usually in the pelvis or lower abdomen. Other symptoms may include back pain, diarrhea or nausea. Dysmenorrhea can occur without an underlying problem. Underlying issues that can cause dysmenorrhea include uterine fibroids, adenomyosis, and most commonly, endometriosis. It is more common among those with heavy periods, irregular periods, those whose periods started before twelve years of age and those who have a low body weight. A pelvic exam and ultrasound in individuals who are sexually active may be useful for diagnosis. Conditions that should be ruled out include ectopic pregnancy, pelvic inflammatory disease, interstitial cystitis and chronic pelvic pain. Dysmenorrhea occurs less often in those who exercise regularly and those who ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaginal Septum
A vaginal septum is a vaginal anomaly that is partition within the vagina; such a septum could be either longitudinal or transverse. In some affected women, the septum is partial or does not extend the length or width of the vagina. Pain during intercourse can be a symptom. A longitudinal vaginal septum develops during embryogenesis when there is an incomplete fusion of the lower parts of the two Müllerian ducts. As a result, there may appear to be two openings to the vagina. There may be associated duplications of the more cranial parts of the Müllerian derivatives, a double cervix, and either a uterine septum or uterus didelphys (double uterus). A transverse septum forms during embryogenesis when the Müllerian ducts do not fuse to the urogenital sinus. A complete transverse septum can occur across the vagina at different levels. Menstrual flow can be blocked, and is a cause of primary amenorrhea. The accumulation of menstrual debris behind the septum is termed cryptomeno ...

OHVIRA Syndrome
Herlyn–Werner–Wunderlich syndrome, also known as OHVIRA (obstructed hemivagina and ipsilateral renal anomaly) is an extremely rare syndrome characterized by a congenital birth defect of the lower abdominal and pelvic organs. It is a type of abnormality of the Müllerian ducts. In most cases, OHVIRA presents as a double uterus–either bicorunate or didelphys– with unilateral obstructed (or blind) hemivagina and ipsilateral renal agenesis (or renal anomalies). It can also affect the urethra, urethral sphincter, ureters, bladder and spleen Although the true incidence is unknown, it has been reported to be between 0.1% and 3%. Development During gestation, the Müllerian ducts fuse laterally with each other and vertically with the urogenital sinus. Incomplete lateral fusion of the upper Müllerian duct segments causes a bicornuate uterus, whereas complete lack of lateral fusion can lead to uterine didelphys (ie, double uterus and cervix). In addition, failed vertical fus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hymen
The hymen is a thin piece of mucosal tissue that surrounds or partially covers the vaginal opening. A small percentage of females are born with hymens that are imperforate and completely obstruct the vaginal canal. It forms part of the vulva and is similar in structure to the vagina. The word is from the Greek ''ὑμήν'' meaning a thin skin or membrane. In children, a common appearance of the hymen is crescent-shaped, although many shapes are possible. Each shape in the natural range has a Latinate name. During puberty, estrogen causes the hymen to change in appearance and become very elastic. Normal variations of the post-pubertal hymen range from thin and stretchy to thick and somewhat rigid. Very rarely, it may be completely absent. The hymen can rip or tear during first penetrative intercourse, which usually results in pain and, sometimes, mild temporary bleeding or spotting. Minor injuries to the hymen may heal on their own, and not require surgical intervention. His ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
