Squamous Cell Carcinoma Of The Vagina
Squamous cell carcinoma of the vagina is a potentially invasive type of cancer that forms in the tissues of the vagina. Though uncommonly diagnosed, squamous cell cancer of the vagina (SCCV) is the most common type of vaginal cancer, accounting for 80-90% of cases as well as 2% of all gynecological cancers. SCCV forms in squamous cells, which are the thin, flat cells lining the vagina. SCCV initially spreads superficially within the vaginal wall and can slowly spread to invade other vaginal tissues. Because of its slow growth, this cancer may cause no symptoms, or it may present with signs like irregular bleeding, pain, or a vaginal mass. This carcinoma can metastasize to the lungs or less frequently to the liver, bone, or other sites. SCCV has many risk factors in common with cervical cancer and is similarly strongly associated with infection with oncogenic strains of human papillomavirus (HPV). Diagnosis of SCCV is done by pelvic exam and biopsy of the tissue. Treatment and progno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oncology
Oncology is a branch of medicine that deals with the study, treatment, diagnosis, and prevention of cancer. A medical professional who practices oncology is an ''oncologist''. The name's Etymology, etymological origin is the Greek word ὄγκος (''ónkos''), meaning "tumor", "volume" or "mass". Oncology is focused on the diagnosis of cancer in a person, therapy (e.g., surgery, chemotherapy, radiotherapy and other modalities), monitoring of patients after treatment, palliative care of people with advanced-stage cancers, Ethics, ethical questions surrounding cancer care, Screening (medicine), screening of patients, and the study of cancer treatments through clinical research. An oncologist typically focuses on a specialty area in cancer treatment, such as surgery, Radiation therapy, radiation, gynecology, gynecologic oncology, geriatrics, geriatric oncology, pediatrics, pediatric oncology, and various organ-specific disciplines (breast, brain, liver, among others).

Constipation
Constipation is a bowel dysfunction that makes bowel movements infrequent or hard to pass. The Human feces, stool is often hard and dry. Other symptoms may include abdominal pain, bloating, and feeling as if one has not completely passed the bowel movement. Complications from constipation may include hemorrhoids, anal fissure or fecal impaction. The normal frequency of bowel movements in adults is between three per day and three per week. Babies often have three to four bowel movements per day while young children typically have two to three per day. Constipation has many causes. Common causes include slow movement of stool within the colon, irritable bowel syndrome, and pelvic floor disorders. Underlying associated diseases include hypothyroidism, diabetes, Parkinson's disease, celiac disease, non-celiac gluten sensitivity, Vitamin B12 deficiency, vitamin B12 deficiency, colon cancer, diverticulitis, and inflammatory bowel disease. Medications associated with constipation in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (PET) scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy. MRI is widely used in hospitals and clinics for medical diagnosis, staging and follow-up of disease. Compared to CT, MRI provides better contrast in images of soft tissues, e.g. in the brain or abdomen. However, it may be perceived as less comfortable by patients, due to the usually longer and louder measurements with the subject in a long, confining tube, although ...

CT Scan
A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists. CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry (medical), gantry to measure X-ray Attenuation#Radiography, attenuations by different tissues inside the body. The multiple X-ray measurements taken from different angles are then processed on a computer using tomographic reconstruction algorithms to produce Tomography, tomographic (cross-sectional) images (virtual "slices") of a body. CT scans can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is Contraindication, contraindicated. Since its development in the 1970s, CT scanning has proven to be a versatile imaging technique. While CT is most prominently used in medical diagnosis, i ...

Chest Radiograph
A chest radiograph, chest X-ray (CXR), or chest film is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures. Chest radiographs are the most common film taken in medicine. Like all methods of radiography, chest radiography employs ionizing radiation in the form of X-rays to generate images of the chest. The mean radiation dose to an adult from a chest radiograph is around 0.02 mSv (2 mrem) for a front view (PA, or posteroanterior) and 0.08 mSv (8 mrem) for a side view (LL, or latero-lateral). Together, this corresponds to a background radiation equivalent time of about 10 days. Medical uses Conditions commonly identified by chest radiography * Pneumonia * Pneumothorax * Interstitial lung disease * Heart failure * Bone fracture * Hiatal hernia * Pulmonary tuberculosis Chest radiographs are used to diagnose many conditions involving the chest wall, including its bones, and also structures contained ...

Vaginal Cytology
Vaginal cytology is a microscopic examination of cells from the vaginal epithelium. In veterinary medicine, it helps differentiate the stages of the mammalian estrous cycle because the vaginal epithelium changes in response to Sex steroid, sex hormone levels; practically, it is used to distinguish when a female Canidae, canine is at a particular point in the estrous cycle. In a normal vaginal Cytopathology#Exfoliative cytology, smear, lactational cells, navicular cells, endocervical cells, endometrial cells, trophoblastic cells, and White blood cell, leucocytes may be present. The equipment needed for vaginal cytology includes a Speculum (medical), vaginal speculum, cotton-tipped applicators, frosted Microscope slide, microscope slides, commercial Romanowsky stain, and Optical microscope, light microscope. Types of cells *Stratum basale, Basal cells - produce all the different epithelial cell types that are observed in a vaginal smear. Basal cells are comparatively small, have a r ...

Colposcopy
Colposcopy ( + ''skopos'' 'look at') is a medical diagnostic procedure to visually examine the cervix as well as the vagina and vulva using a colposcope. The main goal of colposcopy is to prevent cervical cancer by detecting and treating precancerous lesions early. Human Papillomavirus (HPV) is a common infection and the underlying cause for most cervical cancers. Smoking also makes developing cervical abnormalities more likely. Other reasons for a patient to have a colposcopy include assessment of diethylstilbestrol (DES) exposure in utero, immunosuppression, abnormal appearance of the cervix or as a part of a sexual assault forensic examination. Colposcopy is done using a colposcope, which provides a magnified and illuminated view of the areas, allowing the colposcopist to visually distinguish normal from abnormal appearing tissue, such as damaged or abnormal changes in the tissue (lesions), and take directed biopsies for further pathological examination if needed. Colposc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pap Test
The Papanicolaou test (abbreviated as Pap test, also known as Pap smear (AE), cervical smear (BE), cervical screening (BE), or smear test (BE)) is a method of cervical screening used to detect potentially precancerous and cancerous processes in the cervix (opening of the uterus or womb) or, more rarely, anus (in both men and women). Abnormal findings are often followed up by more sensitive diagnostic procedures and, if warranted, interventions that aim to prevent progression to cervical cancer. The test was independently invented in the 1920s by the Greek physician Georgios Papanikolaou and named after him. A simplified version of the test was introduced by the Canadian obstetrician Anna Marion Hilliard in 1957. A Pap smear is performed by opening the vagina with a speculum and collecting cells at the outer opening of the cervix at the transformation zone (where the outer squamous cervical cells meet the inner glandular endocervical cells), using an Ayre spatula or a ...

Rectovaginal Examination
A rectovaginal examination is a type of gynecological examination used to supplement a pelvic examination. In the rectovaginal examination, a doctor or other health care provider places one finger in the vagina and another in the rectum to assess the rectovaginal septum. The examiner will look for any scarring or masses that may indicate cancer or another disease. Typically, a rectovaginal examination is performed to assess pelvic pain, rectal symptoms, or a pelvic mass. It can also provide a sample for fecal occult blood testing, but is controversial for this purpose (see below). Usage as a screening test in asymptomatic women * The rectovaginal examination has marked limitations despite the controlled circumstances of the operating room including general anaesthesia, an empty bladder and ideal patient positioning. As suspected, the specificity of the rectal examination is high due to the low prevalence of disease. However, the sensitivity of the rectovaginal examination is ve ...

Pelvic Examination
A pelvic examination is the physical examination of the external and internal female pelvic organs. It is frequently used in gynecology for the evaluation of symptoms affecting the female reproductive and urinary tract, such as pain, bleeding, discharge, urinary incontinence, or trauma (e.g. sexual assault). It can also be used to assess a woman's anatomy in preparation for procedures. The exam can be done awake in the clinic and emergency department, or under anesthesia in the operating room. The most commonly performed components of the exam are 1) the external exam, to evaluate the vulva 2) the internal exam with palpation (commonly called the ''bimanual exam'') to examine the uterus, ovaries, and structures adjacent to the uterus (adnexae) and 3) the internal exam using a speculum to visualize the vaginal walls and cervix. During the pelvic exam, sample of cells and fluids may be collected to screen for sexually transmitted infections or cancer (the Pap test). Some clinici ...

Medical History
The medical history, case history, or anamnesis (from Greek: ἀνά, ''aná'', "open", and μνήσις, ''mnesis'', "memory") of a patient is a set of information the physicians collect over medical interviews. It involves the patient, and eventually people close to them, so to collect reliable/objective information for managing the medical diagnosis and proposing efficient medical treatments. The medically relevant complaints reported by the patient or others familiar with the patient are referred to as symptoms, in contrast with clinical signs, which are ascertained by direct examination on the part of medical personnel. Most health encounters will result in some form of history being taken. Medical histories vary in their depth and focus. For example, an ambulance paramedic would typically limit their history to important details, such as name, history of presenting complaint, allergies, etc. In contrast, a psychiatric history is frequently lengthy and in depth, as man ...
