Barbed sutures first received US Food and Drug Administration approval for soft tissue approximation in 2005 and early adopters readily embraced this device to develop new techniques. It has become apparent that the advantages are more than just "skin deep." Superficial and deep fascia, cartilage, tendon, joint capsule, and fibrous periprosthetic capsules can also be manipulated. Barbed sutures have revolutionized our approach to facial rejuvenation and body contouring by enhancing our ability to quilt and powerfully lift tissue. The elimination of surgical drains and shorter surgical times has made this a true boon for plastic surgeons as well as many other surgical specialists. This article summarizes some of the current and evolving applications of this exciting new tool.
Is it possible to prevent cytomegalovirus infection? Is there a CMV vaccine? Cytomegalovirus (CMV) infection facts CMV is a common virus in the same family as herpesvirus, and it can infect anyone. CMV is spread by direct contact of body fluids, such as saliva, blood, urine, semen, vaginal fluids, and breast milk. Thus breastfeeding, blood transfusions, organ transplants, and sexual contact are possible modes of transmission. Most healthy people do not experience any symptoms when infected with CMV, and it does not pose a serious health concern. A majority of adults have antibodies consistent with past infection. Most healthy children and adults who do have symptoms will recover from CMV infection without complications and do not require antiviral treatment.
Bronchiectasis is an abnormal dilation of the proximal and medium-sized bronchi (>2 mm in diameter) caused by weakening or destruction of the muscular and elastic components of the bronchial walls. Affected areas may show a variety of changes, including transmural inflammation, edema, scarring, and ulceration, among other findings. Distal lung parenchyma may also be damaged secondary to persistent microbial infection and frequent postobstructive pneumonia. Bronchiectasis can be congenital but is most often acquired.[9] Congenital bronchiectasis usually affects infants and children. These cases result from developmental arrest of the bronchial tree. Acquired forms occur in adults and older children and require an infectious insult, impairment of drainage, airway obstruction, and/or a defect in host defense. The tissue is also damaged in part by the host response of neutrophilic proteases, inflammatory cytokines, nitric oxide, and oxygen radicals. This results in damage to the muscular and elastic components of the bronchial wall. Additionally, peribronchial alveolar tissue may be damaged, resulting in diffuse peribronchial fibrosis.[12] The result is abnormal bronchial dilatation with bronchial wall destruction and transmural inflammation. The most important functional finding of altered airway anatomy is severely impaired clearance of secretions from the bronchial tree. Impaired clearance of secretions causes colonization and infection with pathogenic organisms, contributing to the purulent expectoration commonly observed in patients with bronchiectasis. The result is further bronchial damage and a vicious cycle of bronchial damage, bronchial dilation, impaired clearance of secretions, recurrent infection, and more bronchial damage
Nasal polyps are linked to allergic rhinitis, asthma, aspirin allergy, sinus infections, acute and chronic infections, something stuck in the nose, and cystic fibrosis. But many times the cause is unknown. Sometimes, people get them before they develop asthma or sinusitis
Respiratory syncytial virus (RSV) is a virus that causes infections of the lungs and respiratory tract. It's so common that most children have been infected with the virus by age 2. Respiratory syncytial (sin-SISH-ul) virus can also infect adults. In adults and older, healthy children, the symptoms of respiratory syncytial virus are mild and typically mimic the common cold. Self-care measures are usually all that's needed to relieve any discomfort. Infection with respiratory syncytial virus can be severe in some cases, especially in premature babies and infants with underlying health conditions. RSV can also become serious in older adults, adults with heart and lung diseases, or anyone with a very weak immune system (immunocompromised).
Possible causes are a blocked milk duct or bacteria entering the breast. It usually occurs within the first three months of breast-feeding. Symptoms include breast pain, swelling, warmth, fever, and chills. Antibiotics are required. Mild pain relievers can help with discomfort.
Thalassemia is an inherited blood disorder characterized by less hemoglobin and fewer red blood cells in your body than normal. Several types of thalassemia exist, including alpha-thalassemia, beta-thalassemia intermedia, Cooley's anemia and Mediterranean anemia. Hemoglobin is the substance in your red blood cells that allows them to carry oxygen. The low hemoglobin and fewer red blood cells of thalassemia may cause anemia, leaving you fatigued. If you have mild thalassemia, you may not need treatment. But, if you have a more severe form of thalassemia, you may need regular blood transfusions. You can also take steps on your own to cope with fatigue, such as choosing a healthy diet and exercising regularly.
