The edge of the nails cannot be seen clearly; it seems as though the end of the nail has grown into the flesh of the finger or the toe. The nail, which is fully grown, first loses its shiny look and then shrinks before dropping off. Occasionally, the nail loses its shape too and pus can even grow beneath it. The condition when the nail deteriorates is also known as atrophy. While most cases of onychatrophia are attributed to the nail matrix being damaged, onychatrophia can also be caused by injury and internal diseases.
Staphylococcus aureus and Vibrio vulnificus can also cause very similar infections considered to be Gas Gangrene (Vorvick 2012). Diagnostic Characteristics. The doctor will look for discoloration of the affected area, a yellowing of the skin or a red or brown blister. Also any foul smelling discharge from the area is a positive sign of Gas Gangrene, the discharge can be sampled and tested for a definite conformation that it is an anaerobic, gram positive rod. There is a possibility of a crackling under the skin when compressed slightly, and an inability to contract the muscle in the affected area.
These fluids collect in and around the alveoli, and the alveolar walls thicken. Both events seriously reduce gas exchange and lead to hypoxemia, interfering with oxygenation and possibly leading to death. The capillary leak spreads the infection to other areas of the lung. If the organisms move into the bloodstream sepsis occurs. (3) Etiology: Pneumonia develops when the immune system cannot combat the virulence of the invading organisms.
Also mentioned, is the increased risk of localized hypothermia and risk for infection as wet gauze to the wound can cause vasoconstriction and in theory, also decrease leukocyte mobility and efficiency of phagocytes. Gauze fibers may also be retained in the wound bed further increasing risk of infection. Lastly, the author suggests that the use of wet to dry dressings are not cost effective since they are labor intensive, require secondary dressings to contain exudate, and usually require nursing care within the community. The article closes by saying that further research is needed to fully understand the impact that dressing selection has in wound healing but suggests that practitioners should question the continued use of wet to dry dressings. Currently, Greenville Hospital System’s policy for healing of wounds by second intention is best met with the use of wet to dry dressings.
Infections of the Eye BIO 1015 March 11, 2011 South University Online Eye infections can occur at any time. Eye infections are contagious. Hand washing is a important in prevention of spreading infections. Some eye infections include sty (stye), conjunctivitis, and keratitis. A sty (stye) is a bump on the eyelid (hordeolum).
Ringworm skin lesions normally begin as distinctive, reddish round areas of hair loss, which may progress to reddening, thickening and loss of pigmentation to other skin areas. The Centers for Disease Control and Prevention notes that rash can be dry and scaly or wet and crusty. Treatment • Infected areas must be kept clean. Treat with an over-the-counter fungal product, such as Lamasil. Prescription topical products or pills can be used to treat ringworm in severe cases.
Some people actually confuse their mild outbreaks with other skin conditions such as “eczema”. Early after infection, some people experience prodrome, a tingling, itching feeling that occurs in an area where blisters will shortly develop. Contrary to popular belief, both types can cause genital herpes (Osondu). Transmission is made during contact with a sore or fluid from an infected person, including fetal infection during birth when sores are present on the mother. The reservoirs of the virus are typically ocular, oral, or genital epithelial cells (Hodge).
Also the sheer weight of the uterus pressing down can make emptying the bladder completely difficult so this can help bacteria build up over time until an infection erupts out. Your doctor will be able to diagnosis a UTI from a simple urine test. They will normally prescribe antibiotics to help treat the infection. 2) Bacterial vaginosis This is a common disease that women of child bearing age suffer. It is caused by the imbalance of bacteria in your vagina.
(i) What is the organism involved? Write a short paragraph describing its characteristics and pathogenic potential. What is the challenge to be discussed? Athlete’s foot, also known as tinea pedis, is a fungal infection of feet. It is caused by anthropophilic dermatophytes such as Trichophyton rubrum, Trichophyton interdigitale or Epidermophyton floccosum.
People who are healthy usually recover quickly; however, people who are elderly or people with other medical illnesses are most at risk for a more severe, prolonged infection. There is no specific treatment for Norovirus because it is a virus, and therefore does not respond to antibiotics. It is important to be sure the patient gets enough fluids to avoid dehydration. Noroviruses are found in the feces and vomit of infected people and can spread very quickly in schools, daycares and medical facilities. It is spread through person to person contact, eating food or
