Macrobiopsy of breast lesions is a complicated procedure when performed with vacuum assisted biopsy tools. The Spirotome is a hand-held needle set that doesn’t need capital investment, is ready to use and provides tissue samples of high quality in substantial amounts. In this way quantitative molecular biology is possible with one tissue sample. The Coramate is an automated version of this direct and frontal technology

The average time from symptom onset to diagnosis has been reported to be approximately 2 years. Despite recent attempts at increasing the awareness of pulmonary arterial hypertension (PAH), especially associated PAH (APAH), this delay in diagnosis has not changed appreciably in recent years. Early symptoms are nonspecific. Often, neither the patient nor the physician recognizes the presence of the disease, which leads to delays in diagnosis. Complicating matters, idiopathic PAH (IPAH) requires an extensive workup in an attempt to elucidate an identifiable cause of the elevated pulmonary artery pressure. The most common symptoms and their frequency, reported in a national prospective study, are as follows: Dyspnea (60% of patients) Weakness (19%) Recurrent syncope (13%) Additional symptoms include fatigue, lethargy, anorexia, chest pain, and right upper quadrant pain. Cough, hemoptysis, and hoarseness are less common symptoms. Women are more likely to be symptomatic than men.
Diabetic retinopathy is classified into two types: Non-proliferative diabetic retinopathy (NPDR) is the early stage of the disease in which symptoms will be mild or nonexistent. In NPDR, the blood vessels in the retina are weakened. ... Proliferative diabetic retinopathy (PDR) is the more advanced form of the disease.

Bone marrow examination refers to the pathologic analysis of samples of bone marrow obtained by bone marrow biopsy (often called a trephine biopsy) and bone marrow aspiration. Bone marrow examination is used in the diagnosis of a number of conditions, including leukemia, multiple myeloma, anemia, and pancytopenia. The bone marrow produces the cellular elements of the blood, including platelets, red blood cells and white blood cells. While much information can be gleaned by testing the blood itself (drawn from a vein by phlebotomy), it is sometimes necessary to examine the source of the blood cells in the bone marrow to obtain more information on hematopoiesis; this is the role of bone marrow aspiration and biopsy.
Hepatitis B is a serious disease caused by a virus that attacks the liver. The virus, which is called hepatitis B virus (HBV), can cause lifelong infection, cirrhosis (scarring) of the liver, liver cancer, liver failure, and death. Hepatitis B vaccine is available for all age groups to prevent HBV infection.
At one time, women who had delivered by cesarean section in the past would usually have another cesarean section for any future pregnancies. The rationale was that if allowed to labor, many of these women with a scar in their uterus would rupture the uterus along the weakness of the old scar. Over time, a number of observations have become apparent: Most women with a previous cesarean section can labor and deliver vaginally without rupturing their uterus. Some women who try this will, in fact, rupture their uterus. When the uterus ruptures, the rupture may have consequences ranging from near trivial to disastrous. It can be very difficult to diagnose a uterine rupture prior to observing fetal effects (eg, bradycardia). Once fetal effects are demonstrated, even a very fast reaction and nearly immediate delivery may not lead to a good outcome. The more cesarean sections the patient has, the greater the risk of subsequent rupture during labor. The greatest risk occurs following a “classical” cesarean section (in which the uterine incision extends up into the fundus.) The least risk of rupture is among women who had a low cervical transverse incision. Low vertical incisions probably increase the risk of rupture some, but usually not as much as a classical incision. Many studies have found the use of oxytocin to be associated with an increased risk of rupture, either because of the oxytocin itself, or perhaps because of the clinical circumstances under which it would be contemplated. Pain medication, including epidural anesthetic, has not resulted greater adverse outcome because of the theoretical risk of decreasing the attendant’s ability to detect rupture early. The greatest risk of rupture occurs during labor, but some of the ruptures occur prior to the onset of labor. This is particularly true of the classical incisions. Overall successful vaginal delivery rates following previous cesarean section are in the neighborhood of 70 This means that about 30of women undergoing a vaginal trial of labor will end up requiring a cesarean section. Those who undergo cesarean section (failed VBAC) after a lengthy labor will frequently have a longer recovery and greater risk of infection than had they undergone a scheduled cesarean section without labor. Women whose first cesarean was for failure to progress in labor are only somewhat less likely to be succesful in their quest for a VBAC than those with presumably non-recurring reasons for cesarean section. For these reasons, women with a prior cesarean section are counseled about their options for delivery with a subsequent pregnancy: Repeat Cesarean Section, or Vaginal Trial of Labor. They are usually advised of the approximate 70successful VBAC rate (modified for individual risk factors). They are counseled about the risk of uterine rupture (approximately 1in most series), and that while the majority of those ruptures do not lead to bad outcome, some of them do, including fetal brain damage and death, and maternal loss of future childbearing. They are advised of the usual surgical risks of infection, bleeding, anesthesia complications and surgical injury to adjacent structures. After counseling, many obstetricians leave the decision for a repeat cesarean or VBAC to the patient. Both approaches have risks and benefits, but they are different risks and different benefits. Fortunately, most repeat cesarean sections and most vaginal trials of labor go well, without any serious complications. For those choosing a trial of labor, close monitoring of mother and baby, with early detection of labor abnormalities and preparation for

Have you ever wondered what happens to a painkiller, like ibuprofen, after you swallow it? Medicine that slides down your throat can help treat a headache, a sore back, or a throbbing sprained ankle. But how does it get where it needs to go in the first place? Céline Valéry explains how your body processes medicine.

The term subarachnoid hemorrhage (SAH) refers to extravasation of blood into the subarachnoid space between the pial and arachnoid membranes. SAH constitutes half of all spontaneous atraumatic intracranial hemorrhages; the other half consists of bleeding that occurs within the brain parenchyma. Subarachnoid hemorrhage occurs in various clinical contexts, the most common being head trauma. However, the familiar use of the term SAH refers to nontraumatic (or spontaneous) hemorrhage, which usually occurs in the setting of a ruptured cerebral aneurysm or arteriovenous malformation (AVM).
