Carl Siegmund Franz Credé
Carl Siegmund Franz Credé (23 December 1819 – 14 March 1892) was a German gynecologist and obstetrician born in Berlin. In 1842 he received his doctorate from the University of Berlin. In 1852 he became director of the "Berlin School of Midwives" and chief physician of the maternity division at the Berlin Charité. Later he was appointed professor of obstetrics and director of the maternity hospital in Leipzig. In Berlin and Leipzig, Credé established out-patient gynecology clinics. He was the father of surgeon Benno Credé (1847–1929) and a father-in-law to gynecologist Christian Gerhard Leopold (1846–1912). Among his better known students at Leipzig was gynecologist Johann Friedrich Ahlfeld (1843–1929). Carl Credé is famous for introducing the use of silver nitrate eyedrops as an antiseptic for the prevention of ophthalmia neonatorum in newborns. He used a 2% silver nitrate solution, and first demonstrated its effectiveness in the early 1880s. During a three-y ...

Antiseptic
An antiseptic (from Greek ἀντί ''anti'', "against" and σηπτικός ''sēptikos'', "putrefactive") is an antimicrobial substance or compound that is applied to living tissue/skin to reduce the possibility of infection, sepsis, or putrefaction. Antiseptics are generally distinguished from ''antibiotics'' by the latter's ability to safely destroy bacteria within the body, and from ''disinfectants'', which destroy microorganisms found on non-living objects. Antibacterials include antiseptics that have the proven ability to act against bacteria. Microbicides which destroy virus particles are called viricides or antivirals. Antifungals, also known as antimycotics, are pharmaceutical fungicides used to treat and prevent mycosis (fungal infection). Surgery The widespread introduction of antiseptic surgical methods was initiated by the publishing of the paper ''Antiseptic Principle of the Practice of Surgery'' in 1867 by Joseph Lister, which was inspired by Louis Pasteur's ...

1892 Deaths
Year 189 ( CLXXXIX) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Silanus and Silanus (or, less frequently, year 942 ''Ab urbe condita''). The denomination 189 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Placenta
The placenta is a temporary embryonic and later fetal organ that begins developing from the blastocyst shortly after implantation. It plays critical roles in facilitating nutrient, gas and waste exchange between the physically separate maternal and fetal circulations, and is an important endocrine organ, producing hormones that regulate both maternal and fetal physiology during pregnancy. The placenta connects to the fetus via the umbilical cord, and on the opposite aspect to the maternal uterus in a species-dependent manner. In humans, a thin layer of maternal decidual (endometrial) tissue comes away with the placenta when it is expelled from the uterus following birth (sometimes incorrectly referred to as the 'maternal part' of the placenta). Placentas are a defining characteristic of placental mammals, but are also found in marsupials and some non-mammals with varying levels of development. Mammalian placentas probably first evolved about 150 million to 200 million years ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Credé's Prophylaxis
Credé procedure is the practice of washing a newborn's eyes with a 2% silver nitrate solution to protect against neonatal conjunctivitis caused by ''Neisseria gonorrhoeae''. The Credé procedure was developed by the German physician Carl Siegmund Franz Credé who implemented it in his hospital in Leipzig in 1880. Between 1881 and 1883, Credé published three papers in '' Archiv für Gynäkologie'', each titled "Die Verhütung der Augenentzündung der Neugeborenen" (Prevention of inflammatory eye disease in the newborn), describing his method and its results. The original procedure called for a 2% silver nitrate solution administered immediately after birth; however, this was eventually reduced to a 1% silver nitrate solution to reduce chemical irritation to the newborn's eyes. In the 1980s, silver nitrate was replaced by erythromycin and tetracycline Tetracycline, sold under various brand names, is an oral antibiotic in the tetracyclines family of medications, used t ...

Silver Nitrate Solution
Silver nitrate is an inorganic compound with chemical formula . It is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides. It was once called ''lunar caustic'' because silver was called ''luna'' by ancient alchemists who associated silver with the moon. In solid silver nitrate, the silver ions are three- coordinated in a trigonal planar arrangement. Synthesis and structure Albertus Magnus, in the 13th century, documented the ability of nitric acid to separate gold and silver by dissolving the silver. Indeed silver nitrate can be prepared by dissolving silver in nitric acid followed by evaporation of the solution. The stoichiometry of the reaction depends upon the concentration of nitric acid used. :3 Ag + 4 HNO3 (cold and diluted) → 3 AgNO3 + 2 H2O + NO :Ag + 2 HNO3 (hot and concentrated) → AgNO3 + H2O + NO2 The structure of silver nitrate has been examined by X-ray crystallography sev ...

Ophthalmia Neonatorum
Ophthalmia (also called ophthalmitis) is inflammation of the eye. It results in congestion of the eyeball, often eye-watering, redness and swelling, itching and burning, and a general feeling of irritation under the eyelids. Ophthalmia can have different causes, such as infection from bacteria, viruses, fungi, or may result from a physical trauma to the eye, chemical irritation, and allergies. A bacteria infection can result in a mucus and [pus] secretion. Severe cases of ophthalmia can cause blindness if not treated, especially in newborns, who contract it from the environment in the womb. Treatments vary according to the nature of the cause, with minor irritations going away on their own. Types Types include sympathetic ophthalmia (inflammation of both eyes following trauma to one eye), Neisseria gonorrhoeae, gonococcal ophthalmia, trachoma or "Egyptian" ophthalmia, ophthalmia neonatorum (a conjunctivitis of the newborn due to either of the two previous pathogens), photophthalmi ...
