Salpingitis Isthmica Nodosa
Salpingitis isthmica nodosa (SIN), also known as diverticulosis of the Fallopian tube, is nodular thickening of the narrow part of the uterine tube, due to inflammation. Signs and symptoms SIN is associated with infertility and ectopic pregnancy, and may present as either. Pathology It is characterized by nodular thickening of the tunica muscularis of the narrow (isthmic) portion of the Fallopian tube. In severe cases, it leads to complete obliteration of the tubal lumen. It is uncommonly bilateral. Gross Findings: # One or more nodules 1–2 mm, spanning up to 2 cm # Smooth serosa Microscopic Findings: # Glandular epithelium within tubal muscularis propria, in continuation with mucosa or (more commonly) discontinuous # Haphazard distribution (akin to adenomyosis) or pseudoinfiltrative # Banal epithelium with tubal differentiation Diagnosis Hysterosalpingography, a common technique in the work-up of infertility, is reliable in the diagnosis of SIN, which is seen as small globu ...

Micrograph
A micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times. Micrography is the practice or art of using microscopes to make photographs. A micrograph contains extensive details of microstructure. A wealth of information can be obtained from a simple micrograph like behavior of the material under different conditions, the phases found in the system, failure analysis, grain size estimation, elemental analysis and so on. Micrographs are widely used in all fields of microscopy. Types Photomicrograph A light micrograph or photomicrograph is a micrograph prepared using an optical microscope, a process referred to as ''photomicroscopy''. At a basic level, photomicroscopy may be performed simply by connecting a camera to a microscope, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tubal Obstruction
Fallopian tube obstruction, also known as fallopian tube occlusion is a major cause of female infertility. Blocked fallopian tubes are unable to let the ovum and the sperm converge, thus making fertilization impossible. Fallopian tubes are also known as oviducts, uterine tubes, and salpinges (singular salpinx). Types Approximately 20% of female infertility can be attributed to tubal causes. Distal tubal obstruction (affecting the distal tubal opening (towards the ovary) is typically associated with hydrosalpinx formation and often caused by ''Chlamydia trachomatis''. Pelvic adhesions may be associated with such an infection. In less severe forms, the fimbriae may be agglutinated and damaged, but some patency may still be preserved. Midsegment tubal obstruction can be due to tubal ligation procedures as that part of the tube is a common target of sterilization interventions. Proximal tubal obstruction can occur after infection such as a septic abortion. Causes Most commonly a tube ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gynaecologic Disorders
Gynaecology or gynecology (see spelling differences) is the area of medicine that involves the treatment of women's diseases, especially those of the reproductive organs. It is often paired with the field of obstetrics, forming the combined area of obstetrics and gynecology (OB-GYN). The term comes from Greek and means "the science of women". Its counterpart is andrology, which deals with medical issues specific to the male reproductive system. Etymology The word "gynaecology" comes from the oblique stem (γυναικ-) of the Greek word γυνή (''gyne)'' semantically attached to "woman", and ''-logia'', with the semantic attachment "study". The word gynaecology in Kurdish means "jinekolojî", separated word as "jin-ekolojî", so the Kurdish "jin" called like "gyn" and means in Kurdish "woman". History Antiquity The Kahun Gynaecological Papyrus, dated to about 1800 BC, deals with gynaecological diseases, fertility, pregnancy, contraception, etc. The text is divided into thir ...

Salpingitis
Salpingitis is an infection causing inflammation in the Fallopian tubes (also called ''salpinges''). It is often included in the umbrella term of pelvic inflammatory disease (PID), along with endometritis, oophoritis, myometritis, parametritis, and peritonitis. Signs and symptoms The symptoms usually appear after a menstrual period. The most common are: an abnormal smell and colour of vaginal discharge, fever, nausea, vomiting, bloating, and frequent urination. Pain may be felt during ovulation, during periods, during sexual intercourse, on both sides of the abdomen, and lower back. Causes The infection usually has its origin in the vagina and ascends to the Fallopian tube from there. Because the infection can spread via the lymph vessels, infection in one Fallopian tube usually leads to infection of the other. Risk factors It's been theorized that retrograde menstrual flow and the cervix opening during menstruation allows the infection to reach the Fallopian tubes. Other ...

Vasitis Nodosa
Vasitis nodosa is a complication experienced in approximately 66% of men who undergo vasectomy. It is a benign nodular thickening of the vas deferens, in which small offshoots proliferate, infiltrating surrounding tissue. It can be mistaken for low-grade adenocarcinoma by pathologists, and is implicated in late vasectomy failure.

Chromopertubation
Chromopertubation is a method for the study of fallopian tube patency (a state of being open or unobstructed) for suspected infertility in women caused by fallopian tube obstruction. Occlusion or pathology of the fallopian tubes is the most common cause of suspected infertility. Chromopertubation is sometimes commonly referred to a "laparoscopy and dye" test. It is currently one of the standard procedures in this field. In most cases, chromopertubation is performed to assess and determine the cause of someone's difficulties in getting pregnant. Procedure Chromopertubation is a medical procedure in which blue dye is injected into the fallopian tubes to detect if there are any blockages. It is performed as a laparoscopy, a minimally invasive procedure with small incisions. A laparoscope, a long, fine instrument is inserted into the abdomen close to the umbilicus in order to see one's internal organs, in particular the fallopian tubes. There is also a device called a uterine manipulat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrosalpinx
A hydrosalpinx is a condition that occurs when a Fallopian tube is blocked and fills with serous or clear fluid near the ovary (distal to the uterus). The blocked tube may become substantially distended giving the tube a characteristic sausage-like or retort-like shape. The condition is often bilateral and the affected tubes may reach several centimeters in diameter. The blocked tubes cause infertility. A Fallopian tube filled with blood is a hematosalpinx, and with pus a pyosalpinx. Hydrosalpinx is a composite of the Greek words ὕδωρ (hydōr – "water"Liddell, H.G. & Scott, R. (1940). ''A Greek-English Lexicon. revised and augmented throughout by Sir Henry Stuart Jones. with the assistance of. Roderick McKenzie.'' Oxford: Clarendon Press.) and σάλπιγξ (sálpinx – "trumpet"); its plural is ''hydrosalpinges''. Signs and symptoms Symptoms can vary. Some patients have lower often recurring abdominal pain or pelvic pain, while others may be asymptomatic. As tubal f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hysterosalpingography
Hysterosalpingography (HSG), also known as uterosalpingography, is a radiologic procedure to investigate the shape of the uterine cavity and the shape and patency of the Fallopian tubes. It is a special x-ray using dye to look at the womb (uterus) and Fallopian tubes. It injects a radio-opaque material into the cervical canal, and usually fluoroscopy with image intensification. A normal result shows the filling of the uterine cavity and the bilateral filling of the Fallopian tube with the injection material. To demonstrate tubal rupture, spillage of the material into the peritoneal cavity needs to be observed. Hysterosalpingography has vital role in treatment of infertility, especially in the case of fallopian tube blockage. Uses HSG is considered a diagnostic procedure. It is used in the workup of infertile females to assess the patency of fallopian tubes, assess the competency of the cervix or congenital abnormality of the uterus in multiple miscarriages, assess the patency o ...

H&E Stain
Hematoxylin and eosin stain ( or haematoxylin and eosin stain or hematoxylin-eosin stain; often abbreviated as H&E stain or HE stain) is one of the principal tissue stains used in histology. It is the most widely used stain in medical diagnosis and is often the gold standard. For example, when a pathologist looks at a biopsy of a suspected cancer, the histological section is likely to be stained with H&E. H&E is the combination of two histological stains: hematoxylin and eosin. The hematoxylin stains cell nuclei a purplish blue, and eosin stains the extracellular matrix and cytoplasm pink, with other structures taking on different shades, hues, and combinations of these colors. Hence a pathologist can easily differentiate between the nuclear and cytoplasmic parts of a cell, and additionally, the overall patterns of coloration from the stain show the general layout and distribution of cells and provides a general overview of a tissue sample's structure. Thus, pattern recogniti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunica Muscularis
The muscular layer (muscular coat, muscular fibers, muscularis propria, muscularis externa) is a region of muscle in many organs in the vertebrate body, adjacent to the submucosa. It is responsible for gut movement such as peristalsis. The Latin, tunica muscularis, may also be used. Structure It usually has two layers of smooth muscle: * inner and "circular" * outer and "longitudinal" However, there are some exceptions to this pattern. * In the stomach there are three layers to the muscular layer. Stomach contains an additional oblique muscle layer just interior to circular muscle layer. * In the upper esophagus, part of the externa is ''skeletal muscle'', rather than smooth muscle. * In the vas deferens of the spermatic cord, there are three layers: inner longitudinal, middle circular, and outer longitudinal. * In the ureter the smooth muscle orientation is opposite that of the GI tract. There is an inner longitudinal and an outer circular layer. The inner layer of the muscul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ectopic Pregnancy
Ectopic pregnancy is a complication of pregnancy in which the embryo attaches outside the uterus. Signs and symptoms classically include abdominal pain and vaginal bleeding, but fewer than 50 percent of affected women have both of these symptoms. The pain may be described as sharp, dull, or crampy. Pain may also spread to the shoulder if bleeding into the abdomen has occurred. Severe bleeding may result in a fast heart rate, fainting, or shock. With very rare exceptions the fetus is unable to survive. Overall, ectopic pregnancies are very rare, annually affecting less than 2% of pregnancies worldwide. Risk factors for ectopic pregnancy include pelvic inflammatory disease, often due to chlamydia infection; tobacco smoking; prior tubal surgery; a history of infertility; and the use of assisted reproductive technology. Those who have previously had an ectopic pregnancy are at much higher risk of having another one. Most ectopic pregnancies (90%) occur in the fallopian tube, whic ...
